Renal tuberculosis secondary to systemic disease, it must attach importance to the treatment of local and systemic treatment of lesions comprehensive consideration, if it is satisfied with the results.
(1) systemic treatment of systemic therapy including proper rest and full medical and sports nutrition and necessary medication (including renal tuberculosis of the body other than the treatment of TB lesions).
(2) drug treatment as local lesion of renal tuberculosis and the scope of the extent of the damage are very different, for the treatment of localized lesion in all cases are also different. In the discovery of streptomycin and other anti-TB drugs before clinical diagnosis of renal tuberculosis Once established, the only treatment is nephrectomy. In the 1940s, the streptomycin, Liu ammonia acid have been transformed, many clinical cases of renal tuberculosis drug treatment alone can be cured. After the 1950s, high efficiency, low toxicity and low cost of isoniazid there has taken a combination, the efficacy of renal tuberculosis has greatly improved, almost all early TB can be cured change. 1966 rifampicin to clinical application because the results significantly, and fewer side effects, and the shared use of other drugs, the efficacy of renal tuberculosis raise more. At present due to renal tuberculosis and the need to nephrectomy cases has been greatly reduced. But in some poor sanitary conditions, inadequate medical conditions, there are still the occurrence of renal tuberculosis, and even some advanced patients found. The diagnosis of renal tuberculosis patients, regardless of their degree of disease, whether or not they will need surgery, anti-TB drugs must be taken by certain programmes.
1. Indication of the anti-tuberculosis drug
(1) clinical stage renal tuberculosis.
(2) limitations in a large group within the renal calyceal unilateral or bilateral renal tuberculosis.
(3) isolated renal tuberculosis.
(4) with the activities of other parts of the body tuberculosis temporarily unfit renal tuberculosis surgery.
(5) double focus of renal tuberculosis is not the surgery.
(6) both renal tuberculosis other parts of the serious illness temporarily unfit surgery.
(7) with surgical treatment, as a pre-operative medication.
(8) the post-operative renal tuberculosis conventional medication.
2. Commonly used anti-TB drugs for a variety of types of anti-tuberculosis drugs has its pharmacological characteristics of the drug application requirements and also pay attention to different points. Is a brief introduction commonly used anti-TB drugs is as follows:
(1) Streptomycin: Mycobacterium tuberculosis have bactericidal effect, the concentration in the range of 1.0 μ g / ml effective. Intramuscularly one hour after the largest concentration of the serum, three hours after a decrease of 50 percent, about 60 ~ 90% of the urine from the kidney. PH7.7 role in the system of ~ 7.8, the strongest, lower than the 5.5 ~ 6.0 role decreased significantly. At the same time as the urine alkaline sodium bicarbonate can be taken to enhance its efficacy. Ordinary daily adult dose of 1.0 g, intramuscular injection at 2 with other anti-TB drugs combined, 2 g weekly injection, or every 1 g on the 3rd injection. The treatment allows TB lesions streptomycin fibrosis. If Baixiejitong lesions in the urinary tract, such as the ureter, etc., it could easily lead to shrinkage local fibrosis, the formation of obstruction, should be noted. Streptomycin injection after weeks of mouth numbness, if not serious continue to apply, and often in use gradually disappear. The main side effects of the eighth cranial nerve vestibular-effects. A few cases, there may be allergic shock.
(2), isoniazid (1 NH, Jérémie letters): Mycobacterium tuberculosis suppress and kill role. Daily serving 200 to 300 mg can be satisfactory bactericidal concentration. Oral 1 ~ 2 hours of peak serum concentration. Half-life of six hours, 24 hours can be measured in blood effective inhibitory concentration. General dose to 300 mg daily, a suitable use. This little dose of adverse reactions, it may take a long time, even several years. After taking isoniazid rapid absorption infiltration, fibrosis and cheese of the lesions also easy to infiltrate through the TB lesions promote angiogenesis will enable easier access to anti-TB drugs lesions. The main side effects of the spirit of excitement and multiple peripheral neuritis, it is believed that with increased vitamin B6 or interference from Pyridoxine metabolism and therefore should be combined with isoniazid served vitamin B65 ~ 10mg, to prevent the occurrence of side effects. Serum transaminase medication can be increased, but not to cause liver damage.
(3) ammonia Liu acid (PAS, ammonia acid): Mycobacterium tuberculosis have antimicrobial effect. Medication after 1 to 2 hours up to the peak plasma concentration, 4 to 6 hours after the last trace of blood. Daily dose of 8 ~ 12 g, three to four times taking. The drug less effective alone, but to strengthen isoniazid and streptomycin resistance of Mycobacterium tuberculosis, drug-resistant and can delay occurred. Therefore, in clinical use two or three anti-TB drugs combined to play a role in its treatment. Main side effects are nausea, vomiting, diarrhea and gastrointestinal reactions, it now has been rifampicin, ethambutol replace trend. The goods should not be combined with rifampicin.
(4) rifampicin (RifamPin, RFP): Semi-synthetic broad-spectrum oral antibiotics, the strong growth of cells inside and outside there are strong Killing of Mycobacterium tuberculosis, streptomycin than the ammonia Liu acid, the role of ethambutol stronger, resistant Mycobacterium tuberculosis also effective. Medication 2 ~ 4 hours after drug concentration peak, 12 hours after the serum concentration remains high. Daily dosage of 600 to 900 mg, 1 to 2 minutes, taking fasting. And other non-cross-resistance to anti-TB drugs, isoniazid and ethambutol or combination can be mutually reinforcing role. Few side effects, gastrointestinal reactions and the occasional rash. In recent years have found a few cases of liver damage, increased serum transaminase, such as jaundice.
(5) ethambutol (Ethambutol, EMB): For all types of Mycobacterium tuberculosis have antimicrobial effect. Oral 2 to 4 hours after the peak plasma concentration, and 24 hours after kidney from 50 percent, a small portion of the stool from. Normal renal function had no role in stock. Drug absorption and tissue penetration better, the cheese fiber lesions can also penetrating. Its toxicity is the major role of the ball after optic neuritis, a blurred vision and can not distinguish colors (especially on the green) or a narrow field of vision, severe cases can cause blindness. Optic neuritis is reversible, and more can resume after treatment. The incidence of toxicity and dose. General daily dosage of 600 mg, three times or an oral dose, in this context, less toxic reaction. In the course of treatment should be regularly checked and colour recognition of the vision.
(6) kanamycin: Department of broad-spectrum antibiotics is the main inhibitory effect of Mycobacterium tuberculosis. Oral not absorbed by the gastrointestinal tract, the general amount of 0.75 to 1.0 g daily intramuscular injection. After injection of 30 to 60 minutes of peak blood concentration can maintain about six hours, from the urine within 24 hours from about 90%. Of streptomycin, isoniazid and ammonia Liu acid-resistant Mycobacterium tuberculosis application kanamycin still inhibited. Individual use of easily generate resistance. Streptomycin between unidirectional and cross-resistance, that is, streptomycin-resistant strains can be sensitive to kanamycin, and kanamycin-resistant strains of streptomycin is not sensitive. Therefore, not only with streptomycin or resistant Mycobacterium tuberculosis has been and will be considering applications. Its toxicity is the eighth cranial nerve damage, to permanent deafness may also degeneration of nerve fibers. Slight damage to the kidneys, urine may be a type of protein.
(7), Cycloserine (Cycloserine, Seromycim): broad antibacterial spectrum, a system of Mycobacterium tuberculosis bacteria. But only effective human tuberculosis, TB and to the animals in the test tube tuberculosis is very limited. Of isoniazid, streptomycin, Liu ammonia acid-resistant Mycobacterium tuberculosis by Cycloserine effective. Its role equivalent to ammonia Liu acid, worse than streptomycin. A daily oral dose of not more than 500 mg, general and isoniazid, streptomycin combination. More serious side effects, mainly affecting the central nervous system, such as dizziness, depression, seizures, such as epileptic seizures.
(8) pyrazinamide (Pyrazinamide, PZA): is a new use of old drugs. 1970s found after the oral absorption Pyrazine acid, the effective man-TB can be hidden in the cell to kill the stubborn bacteria. Resistance is expressed very quickly, usually in the medication after one to three months can happen. And rifampin, isoniazid combination treatment can be shortened. For the toxic side effects on the liver, can cause serious acute liver yellow atrophy. Commonly used dose of 1.5 to 2.0 g per day.
In addition to the drugs, there are purple adriamycin (viomycin), B sulfur Isonicotinic amine (ethionamide, 1314), the amount of 0.5 to 0.8 g per day, at 2 to 3 times taking. Ammonia thiourea (P-acetyl aminobenzaldebyde, thiosemica-rbazone, TB1) daily dosage of 500 mg oral dose of 2 points. Tendril adriamycin (capromycin). TB release actinomycin, and other anti-TB drugs and, if necessary, could consider selection.
3. Use of anti-tuberculosis drugs in the clinical application of anti-TB drugs early, generally a single-drug treatment, and now that two or more anti-TB drugs combined. Alone in the treatment of the biggest drawbacks is easy to become drug resistant, but also prone to toxicity. If the combination of two drugs, the emergence of drug resistance time can be extended twice, and can be extended by three drugs three to four times.
(1) anti-TB drugs combined with the choice: a wide range of anti-tuberculosis drug, the ideal should be sensitive to Mycobacterium tuberculosis, in the blood or to be a system of the concentration of sterilization, and the body can endure. The past will streptomycin, isoniazid, as the first-line drugs, ammonia Liu acid as a second-line drugs, others as a third-line drugs. When medication is the preferred first and second-line drugs, and only three drugs in the first line, second-line drugs ineffective or some of them resistant to drugs, before considering the use of. But now the various anti-tuberculosis drugs in-depth study of effect of that isoniazid, rifampin, pyrazinamide, and streptomycin is the first line anti-tuberculosis drugs. Isoniazid strong kill Mycobacterium tuberculosis, Mycobacterium tuberculosis cells both inside and outside the breeding kill, and to thoroughly dry acid into the lesions and macrophages. Rifampin can be split in the short term in the killing of Mycobacterium tuberculosis, and access to renal empty cells and macrophages. Pyrazinamide in the acidic environment of a stronger bactericidal effect can thoroughly into macrophages. Macrophages in the low pH, which is pyrazine amine kill bacteria play a role of the establishments. Streptomycin on tuberculosis split exuberant have a good kill, it thoroughly into TB Vomica.
On the specific application of anti-TB drugs, are now using two or three anti-TB drugs combined. Application abroad streptomycin, isoniazid, Liu acid ammonia three important anti-TB drugs gradually the era of the past, replaced by the new drugs, the new joint. These three drugs in the country is still often used, but also the trend was replaced by rifampin, isoniazid, however in the position of anti-tuberculosis drugs did not change. Now the general isoniazid and rifampicin the two joint, or combined with rifampicin and ethambutol. And streptomycin, rifampicin, pyrazinamide or isoniazid, streptomycin, rifampicin, or isoniazid, streptomycin, ethambutol or isoniazid, rifampicin, ethambutol, etc. the three combined are usually chosen for the clinical.
(2) the application of anti-TB drug treatment: With new and effective anti-TB drugs continue to emerge. Clinical anti-tuberculosis drug treatment has also noticeably changed. In the treatment must adhere to the early, combination, adequate, and adequate period of the Five Principles of medication to obtain the best therapeutic effect. Now used in treatment programmes are as follows:
Long-term therapy: on the application of anti-TB drugs, domestic and international long-term therapy were powered by continued use 18 to 24 months. At least in more than a year. Recognized the efficacy of this method reliable, less opportunity recurrence. Lattimer renal tuberculosis in accordance with the classification of anti-tuberculosis drug treatment, in clinical stage renal tuberculosis medication treatment 1, the lights in a single renal lesions typical of TB medication to two years, and three or more renal calyceal changes to a wide range of tuberculosis require medication for more than three years. Petkovio advocated unilateral renal tuberculosis treatment should last for two years, bilateral renal tuberculosis drug efficacy and the longer the better, it was recommended to last for four to five years, or even more than six years. Now Toman that rifampin and ethambutol composed of “two therapy programme,” and to strengthen the pre-start phase 1 ~ 3, the application of isoniazid, rifampicin and ethambutol or streptomycin three - Joint TB drug use later to continue to stage every four to 12 months of isoniazid and rifampicin, ethambutol or two between the use of anti-tuberculosis drugs, such use, the effects can be significantly enhanced, even if delivery period of 12 months can be achieved within a good effect. Long-term therapy is the main shortcomings of medication for too long, which patients can not adhere to the rules of medication, and often Youlou clothes, and clothes, clothes, and other phenomena of chaos, resulting in bacterial resistance, reduced drug efficacy, positive or urine Mycobacterium tuberculosis sustained TB control After another relapse. According to reports the rules of anti-TB treatment success rate was 90.3%, instead of the rules of treatment success rate of 43.7%.
Short-term therapy: short course’s basic aim is to kill as soon as possible TB lesions in Mycobacterium tuberculosis, a disease tissue repair lasting clinical cure. In recent years the emergence of a new anti-tuberculosis drug sterilization, a range of anti-TB treatment can be. Short-term drug treatment of renal tuberculosis research began in 1970, to 1977 Gow, and other studies to determine short-term drug treatment programme laid the foundation. Now a short course of treatment for four months, two months early for pyrazinamide 25 mg / (kg d) (maximum daily dose of 2 g), isoniazid 300 mg / d, rifampicin 450 mg / d, such as serious kidney and bladder disease Streptomycin may increase by intramuscular injection, 1 g daily; after two months as isoniazid 600 mg three times a week, rifampicin 900 mg three times a week. Gow, in addition to the 140 cases, not one case of medication and relapse, have been cured, in the two months when the medication urinary tuberculosis are to negative, minor drug toxicity. It should be noted, isoniazid, rifampicin and pyrazinamide have liver toxicity, when there are jaundice and elevated liver transaminases should stop until the return to normal again after treatment. Dutt and Sfead application of short-term programme for September, the use of isoniazid and rifampin. For the first month of 300 mg isoniazid, rifampicin 600 mg daily for 1; after eight months to isoniazid and rifampicin 900 mg 600 mg, 2 times a week, results were very good. In short short-term therapy to be successful, needs at least two application modules bactericidal drugs, such as isoniazid, rifampicin, coupled with a semi-sterilization unit drugs, such as pyrazinamide, streptomycin and other. Broad range therapy has the following advantages: ① longer-therapy treatment cut by half or more the time. ② reduce total drug. ③ reduce the chance of chronic poisoning. ④ cost savings. ⑤ easy access to the patients, medication may be rules.
As Mycobacterium tuberculosis growth of a certain degree of regularity, and to 13 / 4 to 31 / 2 days, and Mycobacterium tuberculosis in contact with anti-tuberculosis drugs inhibited their growth, such as contact with streptomycin, pyrazinamide, rifamycin equality, After could delay were growing 8 to 10 days, 5 to 10 days, and 2 to 3 days, the application of anti-TB drugs under intermittent use these features will be intermittent administration in time more than one day, can be achieved Continuous long-term therapy with the same effect. General in the country in the first three months of therapy on long-term medication, later switching to intermittent drug treatment, but the amount of drug therapy with the same long-range, fewer side effects, as well as better efficacy.
(3) the withdrawal of anti-tuberculosis drugs in the standard anti-TB drugs in the course of treatment, must pay close attention to changes in condition, all regular inspection to disease has been cured, they may consider to stop medication. Think we can stop the current standards are as follows:
A. general condition improved significantly, the normal erythrocyte sedimentation rate, body temperature normal.
B. voiding symptoms completely disappear.
C. repeated urine routine examination normal.
D.24-hour urine concentration investigation AFB, long-term inspections are negative.
E. Training urinary tuberculosis, urinary animal inoculation View Mycobacterium tuberculosis were negative.
FX line of urinary performed stability or healed lesions.
G. thorough medical check-no other TB lesions.
After the cessation of medication, the sick need to continue to stress long-term follow-up study, regular urine and urinary inspection performed at least 3 to 5 years.
(C) Although the anti-tuberculosis drug treatment can now be treated in the majority of renal tuberculosis can be cured control, but there is still not part of the patient drug to be effective, and treatment remains to be done. Including full nephrectomy surgery, and some nephrectomy, such as removal of kidney lesions in several ways, depending on the scope of diseases, the extent of damage and the effects of drug therapy chosen.
1. Whole nephrectomy
(1) Full-nephrectomy indications: ① unilateral renal lesions of tuberculosis in the destruction of more than 50 per cent larger. ② destruction of the entire renal tuberculosis renal function has been lost. ③ tuberculosis renal abscess. ④ bilateral renal tuberculosis, and severely damaged the side and the other side for the very mild tuberculosis, with a need to serious side, mild lesions side by drug treatment. Since the cut-off plaster ⑤ renal calcification.
(2) nephrectomy before and after the application of anti-tuberculosis drugs: As the body of renal tuberculosis is part of tuberculosis, TB is the secondary, urinary tuberculosis is a part of the period when nephrectomy can be a result of surgery Damage to reduce the resistance of the body, other than the result of renal tuberculosis or TB lesions caused Disseminated, in nephrectomy before and after the application of anti-TB drugs must be controlled.
1) nephrectomy before antituberculotics preoperative preparation: antituberculosis drugs before surgery by the preparations for the selection of varieties and medicinal doses, with the same general anti-tuberculosis treatment. But in the use of methods and the use of the time to be different. Such as isoniazid 100 mg three times daily oral, streptomycin 0.5 g, 2 times a day intramuscular injection, rifampicin 300 mg orally twice a day, every day for the application of application, sustained two weeks, and reoperation. If patients with systemic poor, or any other organ tuberculosis, as appropriate, should extend the preoperative preparation of anti-tuberculosis drugs, and sometimes preoperative medication may be extended to three to four months. Needed after such application until after physical rehabilitation, about two weeks after the turn around conventional anti-TB treatment.
2) nephrectomy after the application of anti-tuberculosis drugs: the urinary tuberculosis, renal tuberculosis is the primary lesion, when after resection of renal disease, urinary system will be only the original lesion resection, there are still remnants of tuberculosis after Variable presence of these residues ureter and bladder Tuberculosis Tuberculosis Tuberculosis other organs or body still needs the light of the choice of anti-TB drugs and long-term or short-term treatment of schedule until the complete urinary tuberculosis control and stop.
2. Part nephrectomy
(1) of nephrectomy indications: ① confined to the kidney to a pole in the 1 to 2 small renal calyceal the devastating disease, the long-term anti-tuberculosis drug treatment was ineffective. ② 1,2 small renal calyceal TB Department narrow funnel to poor drainage. ③ bilateral renal tuberculosis destruction轻而long-term drug therapy ineffective. If kidney function is the only required part of renal surgery, should be retained at least 2 / 3 of the renal tissue, so as to avoid postoperative renal insufficiency caused.
(2) of nephrectomy before and after the application of anti-tuberculosis drugs: As the anti-tuberculosis drug treatment often received good results, some less nephrectomy, the patients suitable for this operation should be a longer period of time antituberculotics prepared before implementation. General preoperative preparation to use 3 to 6 months. Preoperative angiography yet again, the decision to establish lesions after surgery.
I left after surgery because of the kidney and urinary organs TB, it will continue to use anti-TB drugs for at least one year to consolidate the effect.
3. Removal of kidney lesions
(1) removal of the kidney lesions indication: the essence of the kidney in renal calyceal confined formed by tuberculosis empty, and often filled with cheese - like substance. Antituberculosis drugs can not enter the hollow, empty and there are still activities in the presence of Mycobacterium tuberculosis. It is necessary to open empty, remove cheese - like tuberculosis, reuse antituberculotics cavity.
(2) before and after operation also required a longer period of application of anti-TB drugs, and to prevent disseminated tuberculosis treatment after the consolidation.
(D) the treatment of bladder contraction TB bladder contraction of cystitis serious consequences, often in serious bladder tuberculosis healing process gradually taking shape. Treatment methods as follows:
1. By nephrectomy in the treatment of tuberculosis, or TB control variable, seeking to expand the bladder. Contracture in a lesser individual cases, the patient gradually extended training time between urination, bladder capacity is gradually increasing. Can use this method of cases less serious contracture is not used.
2. Drug treatment due to serious inflammation of the bladder tuberculosis alternating with the healing process, in the urinary tract treatment of primary lesion, it should proceed with the treatment. The author has introduced a more Yu (guaiazulene), pyrazinamide (ZA), oxygen chlorine acid (clorpactin XCB), the treatment of bladder tuberculosis, and expand the capacity of the bladder to prevent the occurrence of contracture. Oxygen chlorine acid is an effective fungicide for use in the bladder irrigation water can be released from hypochlorite (hypochlorous acid) to achieve sterilization purposes, removal of bladder lesions in the necrotic tissue from expanding creative use of the normal mucosa without any damage, lesions can heal, bladder capacity increased. But now bladder scar contraction, despite washing can not increase capacity. Lattimer highlighted in the local irrigation, yet at the same time application in the treatment of systemic anti-tuberculosis.
3. Surgery for a clear diagnosis of bladder contraction, in 50 ml capacity below, and not the conservative treatment of bladder capacity to expand, it should consider expanding bladder surgery. Bladder approach is to expand the use of free-intestinal and bladder anastomosis, free of the past is the application of the ileum, although free of the ileum of the activities of large, easy and bladder contraction for anastomosis, but because many of the ileum after expanding bladder patients will ileum of the expansion, loss of tension, to pass urine retention in the expanded bladder not emptying, so now basically have not adopted. Applications currently are generally free of the colon to expand the bladder. Colon to the merits of strong contraction. Colon applications within 12 cm in length. Bladder coincide with the approach adopted cat-tail anastomosis. If patients in bladder contraction while tuberculosis ureter stenosis or Lower Ureteral stricture tuberculosis, should be expanded in the bladder, ureter will narrow over the cut, top ureteral re-anastomosis with a free colonoscopy. If the bladder contraction of the urethral stricture of tuberculosis exist unless it can urethral stricture expansion to be resolved, otherwise it is not appropriate to expand the contracture bladder surgery, only to abandon the purposes of the bladder and urinary diversion suitable.
(5) the treatment of contralateral hydronephrosis contralateral hydronephrosis need to be addressed, the urinary system must have a comprehensive understanding of, such as the degree of hydronephrosis and ureter expansion of the state, lower ureter, the narrow whether ureteral orifice, bladder whether contracture, and the extent of contracture. Finally choose the right treatment options. General treatment options have the following categories:
1. Contralateral kidney ureter mild to moderate expansion of the merger water bladder contraction: in the treatment of bladder contraction in accordance with the surgical treatment of sigmoid colon and bladder, ureter and expand the colon for anastomosis.
2. Contralateral kidney ureter mild to moderate expansion without water bladder contraction (by water or ureteral orifice by the Lower Ureteral stricture): treatment for a cut or ureteral dilatation of the stricture of the distal ureter or expansion . If expansion can not succeed, they may consider a cut after the ureter and bladder re-anastomosis.
3. Contralateral kidney ureter expansion of water caused severe renal dysfunction: kidney should be held water drainage operation. There are two methods of operation:
(1) temporary kidney stoma surgery: kidney, ureter severe water can be used for renal stoma surgery. Stoma in the urine drainage for a considerable period of time, if the expansion narrow, water change or disappear, renal function returned to normal, can only expand further bladder surgery in the transplant ureter bladder wall in the expansion. Subsequent removal of the kidney stoma catheter.
(2) permanent drainage: If renal stoma after water has not changed, nor narrow the ureteropelvic expansion can be renal catheter permanent stoma remain in the pelvis, long-term drainage. If the renal pelvis and ureter expansion of water and there is no serious chance of urinary repair the original channel can be directly ostomy permanent kidney or ureter expansion of the purposes of the skin graft or bladder with ileum (Bricker surgery). Consider drainage and difficult to restore permanent normal urinary voiding following several conditions: ① urethra with severe tuberculosis, it is estimated that difficult to repair the urinary patency. ② bladder contraction extremely serious, it is estimated that difficult to expand the bladder. ③ merger intestinal tuberculosis, peritoneal tuberculosis or other gastro-intestinal diseases. ④ water renal serious obstacle to the resumption of operation is estimated to be competent minor electrolyte disordered. ⑤ The patient is in very poor and can no longer implement molding surgery.
(6) TB spontaneous rupture of the bladder because of the treatment of bladder tuberculosis spontaneous rupture of renal tuberculosis is a serious late complications. Often in the bladder rupture patients before symptoms of urinary tuberculosis, and often rupture after acute abdomen cases. If not diagnosed early exploratory laparotomy should be clear to avoid bungled rescue time. For TB spontaneous rupture of the bladder should be implemented as soon as possible surgery to repair the bladder perforation, and bladder ostomy. Before and after surgery should be routinely taking anti-TB drugs. According to subsequent renal tuberculosis lesions for further processing.
