[Current approach to solving the problem of urolithiasis].

The article analyses experience in the management of about 1,500 patients with urolithiasis who underwent in- and out-patient treatment at the Urological Clinic of the Moscow Regional Scientific Research Clinical Institute in 1990-1993. Indications were determined for applying lithotripsy in patients with stones in anomalous kidneys, in cases of a solitary kidney, and children with urolithiasis. The tactics of management of large kidney stones is described. The use of endoscopic methods of treatment (percutaneous and transurethral) is evaluated. Modern methods of urolithiasis treatment were applied instead of an open operation in 90% of patients.

[Maxaquin and ciprofloxacin in the treatment of complicated and recurrent urinary infections in adults].

Clinical efficacy of maxaquin versus ciprofloxacin against complicated or/and recurrent urinary infections (62 patients primarily with chronic pyelonephritis with nephrolithiasis) proved higher (92.3% vs 80.0%) in equal microbiological activity (73.2% vs. 73.4%) of the drugs. Maxaquin was less active in enhancing the culture resistance. Both quinolones had no negative effects on the studied systems of the body's antiinfectious resistance and promoted partial correction of dysbiotic manifestations on the colon mucosa. Side effects of both drugs occurred with similar frequency and severity, starting earlier in administration of maxaquin. The authors offer to manage urinary infections in adults effectively with maxaquin in a dose 400 mg once a day and ciprofloxacin in a dose 500 mg twice a day by 7-14-day courses.

[The functional assessment of the renal parenchyma and perirenal fatty tissue during electropiezolithotripsy by x-ray computed tomography].

Computed tomography was performed before and after telelithotripsy to evaluate changes in renal parenchyma induced by the procedure in 34 patients with nephroliths. Piezolith-2300 lithotriptor ("Wolf", FRG) was employed. The images showed no serious parenchymal injuries or paranephric hematomas, on the one hand, but density changes in the parenchyma, on the other hand. These were of 3 types: focal reduction in 3, diffuse reduction in 4 and diffuse increase of the density in 2 patients. As shown by comparison with literature data, telelithotripsy on "Piezolith-2300" causes minimal changes in renal parenchyma and perirenal fat. In view of this, the procedure is recommended for wide clinical and outpatient practice.

[Use of extracorporeal shockwave lithotripsy for kidney calculi].

278 patients with coral nephrolithiasis were examined in 1990-2003. Extracorporeal shock-wave lithotripsy was made in 46 (16.5%) patients with 48 coral stones (mean age 48.2 +/- 18.3 years) as a basic treatment. The length of the concrement was 4.9 +/- 1.8 cm, width 3.8 +/- 1.4 cm, a relative area 19.72 +/- 13.01 cm2. All the patients have initially undergone internal drain of the kidney by a catheter (n = 13) or stent (n = 33). Each lithotripsy session included, on the average, 2882 +/- 318 impulses (17-19 kV). The number of high-energy impulses per a session comprised 342 +/- 23. A total number of the sessions reached 3.4 +/- 1.55. Initial destruction of the concrement requires 1.6 +/- 0.6 sessions in 10144 +/- 1081.2 impulses per one patient including 1436 +/- 96.6 high-energy impulses. One procedure comprises 2-3 sessions of lithotripsy with a 5-7 day interval. The results were assessed at discharge after the first session and 6 months later, the degree of stones elimination from the kidney, complications, manipulations to manage the complications. At discharge after 3 lithotripsy sessions recovery was achieved only in 3 out of 46 (6.52%) patients. Six months later the fragments eliminated in 26.1% (12 of 46 patients). Monolithotripsy caused complications in 13 patients. Additional manipulations made up 65.2%. Inefficacy of explorative treatment necessitated conversion to open intervention in 6 (13.1% 0 patients. The use of extracorporeal lithotripsy as a monotherapy in coral nephrolithiasis is now limited.

[Ureterocele and urolithiasis].

We studied 51 patients with true ureterocele (primarily, orthotopic and unilateral--84.3 and 82.3%, respectively) combined with urolithiasis. Mean age of the patients was 41.9 +/- 2.0 years, size of ureterocele--20.7 +/- 1.3 mm and mean concrement area--1.4 +/- 0.2 cm2. In adult patients with orthotopic or heterotopic disease surgery consisted of perforation (n = 5) or dissection of ureterocele wall (n = 38). Endoscopic operations were indicated in small and middle sized ureterocele (less than 30 mm in size), unaffected contractility of terminal ureter, moderate urodynamic disorders of the upper urinary tracts, normal function of the kidney and no pyelonephritis exacerbation. Endoscopic section of ureterocele wall combined with ureterolithoextraction (n = 26), contact ureterolithotripsy using Ho:YAG laser or ultrasound (n = 19). Open surgery (ureterocystoneostomy by Politano-Leadbetter was made in orthotopic ureterocele over 30 mm in size and in marked urodynamic disturbances of the upper urinary tracts (n = 6). At discharge, a complete elimination of the stones in ureterocele patients was 81.6%. Effective use of extracorporeal shock-wave lithotripsy of nephroliths within 2 months after removal of ureterocele raised this percent to 87.7. Thus, choice of surgical policy in ureterocele complicated by urolithiasis depends on its size, variant of combination of this defect with the concrement, anatomofunctional state of the upper and lower urinary tracts, age of the patient and presence of pyelonephritis.

[Extracorporeal shock-wave lithotripsy in the treatment of urolithiasis of dystopic kidneys].

The 10-year experience of the urological clinic of M.F. Vladimirsky Research Clinical Institute included treatment of 219 patients (age 21-68 years, mean age 52.3 +/- 12.4; 59.2% females, 40.8% males) with urolithiasis which developed in the presence of anomalies of the kidneys and upper urinary tract. Uroliths were detected in the kidneys with homolateral (n = 51, 23.7%), lumbar (n = 49), iliac (n = 1), pelvic (n = 2) dystopia. Chest and heterolateral dystopia of the kidneys were not detected. Extracorporeal shock-wave lithotripsy (ESWL) was used in 38 (77.6%) patients, 11 (22.4%) patients were treated by other methods. A short-term effect of ESWL consisted in elimination of most of the concrement fragments while the residual fragments had no clinical symptoms being maximally 4-5 mm in size. It was noted in 23 of 38 (60.5%) patients. Six months after ESWL elimination of the concrement from lumbar-dystopic kidney occurred in 27 (71.05%) of 38 patients. Residual fragments 6-10 mm in size were registered in 26.35% patients, more than 10 mm--in 1 (2.6%). Complications after ESWL monotherapy of the concrements of the lumbar-dystopic kidney were seen in 26.3% (acute pyelonephritis 10.6%, stone track--7.9%, total hematuria--2.6%, acute prostatitis--2.6%, renal colic--2.6%). Mean treatment duration was 15.4 +/- 3.3 days. Thus, most effective therapy ofdystopic kidneys urolithiasis is ESWL the total efficacy of which reached 71.05%.

[Reasons for the late diagnosis of Reiter's disease].

The main causes of the delay in reaching the appropriate diagnosis of Reiter's disease were analysed. It was concluded that even if the only sign from the disease symptomatic triad (mainly slowly progressing nonspecific urethritis or prostatitis) was observed, Reiter's disease should be suspected and its verification include immunological techniques. Tetracycline antibiotics were found to be mandatory indicated as an etiotropic treatment.

[Endourethral phonophoresis of lipase in the combined treatment of strictures of the urethra].

Poor results of surgical treatment of posttraumatic and inflammatory urinary strictures have urged the authors to the search and introduction into clinical practice of a multimodality conservative treatment combining conventional urethroplasty, transurethral manipulations with following local endourethral lydase phonophoresis. The treatment has been conducted in 104 men aged 15-78. The final analysis of the trial demonstrated the advantages of the proposed method as to the duration of the treatment and prevention of the strictures recurrences. Detailed consideration is given to the indications, technique, long-term response. The objective approach has been achieved by tracing dynamic changes in the low urinary tract.

[Treatment of strictures of the urethra in men].

Treatment of urethral strictures was conducted in 84 male patients, aged 15 to 78 years. Combined treatment included optical (retrograde and antegrade) urethrotomy and transurethral electroresection (TUR) of scar tissues, combined with postoperative endourethral phonophoresis with lidase (64 units) and an antibiotic. Retrograde urethrotomy was performed under visual control. Scar tissues were dissected layer by layer until the resectoscope could be introduced. Antegrade urethrotomy was performed after bougies were passed through the stricture. To improve the results of endourethral surgery, all patients underwent endourethral lidase and antibiotic phonophoresis, using "C" irradiator of the Soviet Sterzhen' device, on postoperative day 3. The duration of phonophoretic session was 6 to 12 min at 0.1-0.3 kW. There were 8 to 10 sessions to a course of physiotherapy. This combined treatment stabilized urodynamic parameters at 1 to 1.5 years' follow-up, as evidenced by significantly increased mean and peak urinary flow rate and shorter bladder evacuation time. There were basically no postoperative relapses in 92.1% of the patients.
