[Extracorporeal shock-wave lithotripsy of bladder stones in patients with benign prostatic hyperplasia].

In urological department of Moscow Regional Research Clinical Institute, extracorporeal shock-wave lithotripsy (ECSWL) or bladder stones in patients with benign prostatic hyperplasia (BPH) has been made prior to TUR from 1991. This treatment was given to 52 patients aged 54-79 years with prostatic volume 40-120 cm3. Complete or partial fragmentation of the vesical calculi was achieved after 1 to 3 ECSWL sessions (a total of 105 sessions, 2000-3000 impulses a session). Pretreatment with ECSWL of bladder stones significantly facilitates TUR in BPH patients with vesical calculi of big size (2.5 cm and more in diameter). Extracorporeal fragmentation of large stones prior to TUR makes surgery of such patients less traumatic and reduces the risk of intraoperative complications compared to endoscopic cystolithotripsy or cystolithotomy. ECSWL of cystolithes expands indications for drug therapy or thermal non-endoscopic BPH treatment in aged patients with poor somatic status and in young sexually active males rejecting surgery.

[Algorithms of diagnostic radiation methods in current urological pathology].

Based on the results of 3600 studies using all basic methods of modern radiation diagnosis, the authors show it necessary to develop diagnostic algorithms applicable to certain groups of urological diseases (urolithiasis, inflammatory processes and bulky masses in the kidney). This necessity has recently stemmed from the advent of new technologies of radiation diagnosis and from the expediency of using a certain method at the specific stage of examination. At the same time, the authors underline the importance of using standardized examination programmes (algorithms) in practice, which is also due to the fact that unreasonable use of the whole set of new radiation techniques that are of highly diagnostic value may bear great material costs.

[Comparative analysis of open and endoscopic operative procedures outcomes for posterior urethra obliteration in males].

Endoscopic recanalization of posterior urethra (PU) obliteration (a novel method) was compared to open reconstructive-plastic operations. 242 patients with PU and vesicular cervix obliterations entered the study. 93 patients of group 1 have undergone open reconstructive-plastic operations, 149 patients of group 2 were operated endoscopically (endoscopic recanalization under transrectal ultrasonic control). Before surgery the patients were examined using standard tests, sonourethrography and intraoperative transurethral ultrasonic investigation were added. Recurrence rate in group 1 and 2 was 29.1 and 16.8%, respectively. The following complications were observed in group 1: acute pyelonephritis (22.5%), enuresis (14%), orchoepididymitis (9.7%), urinary fistulas (5.4%). The patients needed long-term postoperative immobilization (10-16 days, mean 14.8 +/- 1.1 days). After endoscopic recanalization under transrectal ultrasonic control, group 2 patients developed acute pyelonephritis (4.8%), orchoepididymitis (4%), orthostatic enuresis (4%), short-term urethral fever (85.9%). Bed regime in this group was necessary for 1-2 days (1.3 +/- 0.4 days). Mean postoperative hospital stay was 2.5-fold less in group 2. The conclusion is made that endoscopic recanalization under transrectal ultrasonic control has advantages over open reconstructive-plastic surgery: less frequent pyoinflammatory complications, enuresis, the absence of such complications as impotence, short penis, formation of urinary fistulas.

[The TVT operation in injury of the pelvic ring].

The authors report a case of a woman with combination of stress urinary incontinence (SUI) with posttraumatic rupture and divergence of the pubic joint. The latter led to relaxation of the pelvic base and urethral ligaments resultant in SUI. The patient was treated surgically (a modified TVT operation). This rare case demonstrates possibility of SUI development consequently to trauma of the pelvic ring and a TVT operation efficacy made in non-standard setting.

[Reconstruction of long recurrent strictures of the anterior urethra with a free transplant of buccal mucosa].

The study included 18 patients with recurrent strictures of the anterior urethra. In 16 patients the recurrence arose after several endoscopic operations for inflammatory urethral strictures, in 2--after plastic repair of the stricture by loganson and plastic treatment of hypospadia. The strictures varied in length from 3 to 16 cm. Ventral flap of buccal mucosa was used for plastic reconstruction in 16 patients, dorsal flap--in 2 patients. Follow-up lasted from 1 to 15 months. All the patients were cured. The intubation drainage was removed 4-7 weeks after the operation. Qmax elevated, on the average, from 4.79 +/- 0.78 to 29.5 +/- 1.94 ml/s. The recurrence developed only in 1 patient 6 months after the plastic repair. The patient was successfully operated (internal optic urethrotomy). Thus, short-term outcomes of urethroplasty with buccal transplant showed this operation to be highly effective in correction of long recurrent strictures of anterior urethra in males.

[Hyperthermia as a method for treating prostatic adenoma].

Local microwave hyperthermia was used in 15 patients aged 60 to 76 years with prostatic adenoma on an inpatient (n = 8) and outpatient (n = 7) basis. Severe clinical symptoms of prostatic adenoma was considered indication and urinary and prostatic stones were contraindications. Every patient received 6 hyperthermia treatments (41 to 42 degrees C) with a 915 or 460 MHz device. Adenoma of the prostate was treated twice a week. An interval of 3-4 days was used to avoid thermic tolerance. The treatments were well tolerated. Prostatic size was reduced by 15.2 cm2 in 11 patients and unchanged in 1 patient. Three patients required surgery 2 weeks after treatment withdrawal because of adenoma distension with residual urine and 3 patients were operated on for cystostomes. The overall effect of microwave hyperthermia on prostatic adenoma was induction of focal sclerosis in adenoma. This treatment improved uroflowmetric findings and abolished residual urine. Hyperthermia is a reasonably safe conservative option for inoperable patients with prostatic adenoma.

[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.

[Extracorporeal lithotripsy in certain forms of urolithiasis].

Therapeutic results of remote lithotripsy have been analyzed for 1016 patients with urolithiasis. The authors also focus on specific features of remote lithotripsy in anomalous stones, in nephroliths on the single and transplanted kidney, in location of the stone in the ureter. The efficacy of the procedure is reviewed in pediatric patients. Satisfactory results were achieved in 962 patients (95%). Remote lithotripsy is considered to be a valuable component of combined treatment of urolithiasis replacing successfully open surgery in 95% of the cases.

[The international system of overall scoring assessment of the symptoms and quality of life of patients with benign prostatic hyperplasia].

The paper presents the International system of overall score estimation of symptoms and life quality for patients with benign prostatic hyperplasia and reviews the results of this system application for objective diagnosis and evaluation of the efficacy of the treatment (chemotherapy, transurethral resection, transvesicular adenomectomy, transrectal hyperthermia, YAG-Nd laser prostatectomy) in 250 patients with benign prostatic hyperplasia. The fault of the system is the absence of specific recommendations for rating objective test results. The authors propose their variant of estimation of prostatic volume, maximal urination rate, residual urine.

[Transurethral resection in patients with benign prostatic hyperplasia complicated by chronic calculous prostatitis].

Combination of benign prostatic hyperplasia (BPH) with chronic calculous prostatitis aggravates clinical symptoms of BPH and complicated its treatment. Pronounced dysuria, persistent pain are highly resistant to conventional chemotherapy. Prostatic stones promoted emergence of sclerotic and purulent complications impeding surgical treatment of BPH. Unsatisfactory results of transurethral resection (TUR) in BPH with chronic calculous prostatitis are attributed to impossibility to remove all the concrements. Visual control in TUR cannot localize the stones. Deep resection of the prostate at the site of expected stone location elevates the risk of enuresis and impairment of prostatic capsule. Surgical treatment of 16 patients has demonstrated that removal of all the concrements and prevention of the complications are possible under transrectal ultrasound control.

[The treatment of obliterations of the posterior urethra in men].

The paper presents the analysis of treatment results for 345 patients with posterior urethra obliteration treated in 1981-1996. Of the various methods used, endoscopic operations proved most effective and safe. Two-stage recanalization of the posterior urethra is more sparing than plastic surgery as it does not employ traumatic approach, is shorter, is accompanied but less blood loss, makes postoperative complications less frequent. A novel treatment (endoscopic recanalization of the urethra under transrectal control) is much less traumatic, makes complications rare. Open plastic operations on the urethra should be made only in cases when obliteration of the posterior urethra is combined with urinary fistulas and when femur bones deformation induces urethral deviation.
