[Non-transecting anastomotic urethroplasty for strictures of the bulbar urethra. Systematic review].

The results of using non-transecting anastomotic urethroplasty in men with bulbous urethral strictures are presented in the review. A total of 25 original publications were found, including 20 foreign and 5 Russian articles. The studies included from 1 to 358 patients who underwent anastomotic urethroplasty without transection of the corpus spongiosum (average number of patients in a study was 54). Etiological factors were indicated in 17 articles. Most studies (10 out of 17) indicated idiopathic etiology as the predominant one. There was no correlation between the results of the procedure and the etiology of urethral stricture. The mean length of urethral stricture in the vast majority of studies was less than 2 cm, and only in a few studies it was larger, with a maximum mean value of 3.9 cm. Postoperative complication rates were reported in 20 studies and ranged from 0% to 23.9% within one study (median 8.4%). In general, mild complications occurred, corresponding to category I-II according to the Clavien-Dindo classification. The incidence of erectile dysfunction was evaluated in 18 studies and ranged from 0% to 23% (average value of 6.5%). The success of non-transecting anastomotic urethroplasty averaged 94.7% (82-100%) with a median postoperative follow-up of 24.5 months (3-150 months). In 9 out of 25 studies, an additional comparison with transecting technique was done. In 6 studies, the superiority of the non-transecting technique in terms of treatment success and preservation of sexual function was found. The obtained results showed the high efficiency and safety of non-transecting anastomotic urethroplasty in case of short strictures of the bulbous urethra.

[Giant prostate stones: case report].

Small prostate stones are often found incidentally during clinical and radiological examination. Large stones, however, also may develop, replacing completely the prostate tissue and causing various symptoms. Such a large stones are commonly formed due to chronic urine reflux. There are 20 publications in the literature devoted to the patients with giant prostate stones. Open as well as endoscopic procedures can be performed. In our clinical case both approaches were done simultaneously. Such tactic was chosen in order to carry out a single-stage intervention, immediately solving two problems, i.e., urethral stricture and a giant prostate stone.

[Perineal urethrostomy: results, clinical, statistical and terminological aspects].

The analysis of the results of perineal urethrostomy for urethral stricture in men for the period from 2000 to 2020 is presented in the article. We identified 29 original articles devoted to this technique, including 4 Russian and 25 foreign publications. In two studies, there were more than 100 patients, four studies included from 51 to 77 men, and in remaining studies less than 50 patients were analyzed. Complete data on all pre- and postoperative aspects of perineal urethrostomy were provided only in a few studies. In the overwhelm of cases, perineal urethrostomy was performed after one or several unsuccessful reconstructive procedures and only in few patients it was done prior to various types of urethroplasty. It was not possible to establish any association between etiological factors and localization of urethral stricture among these patients. The incidence of pan-urethral stricture ranged from 28.6% to 100%. Only in one study the average stricture length was 2 cm, while in all other studies it was 5 cm or more. Postoperative follow-up was on average 14 to 62 months. Treatment success with perineal urethrostomy ranged from 0% to 100%, but in most studies it was 75% or more. The most common perineal urethrostomy technique used included Blandy technique, and Johanson and 7-flap techniques.

[Non-transecting anastomotic urethroplasty].

The review analyzes the results of using non-transecting anastomotic urethroplasty in men with urethral strictures. Identified 14 original studies using this technique: 13 foreign and 1 Russian. In total, this technique was applied in 704 patients. This technique was used in 85% of cases with bulbar urethral stricture, in 15% - with posterior stricture.The average length of the urethral stricture in all studies was less than 2 cm, except for two works, where the average stricture length was 2.3 cm and 3.9 cm, respectively. This technique is equally successfully applied in all etiological variants of urethral stricture. The incidence of postoperative complications in all studies using non-transecting anastomotic urethroplastyaveraged 13.7%.Postoperative complications were mostly mild and corresponded to G1 according to Clavien-Dindo classification.According to 10 out of 14 studies that evaluated the effect of surgical treatment on the occurrence of erectile dysfunction (ED), the incidence of ED de novo was on average 13.4%. The success of treatment with the use of non-transecting anastomotic urethroplastyaveraged 95% (82-100%) with a median postoperative follow-up of 27 months (6-64 months). In 4 out of 14 studies, an additional comparison was transecting versus non-transecting techniques. Non-transecting technique was not inferior to transecting technique by any criterion, but, on the contrary, exceeded it in a number of indicators, including the dynamics of sexual function after surgery.On the basis of available studies on the use of non-transecting anastomotic urethroplasty, this technique should be recognized as a highly efficient and reasonably safe method for treating short urethral strictures and recommended for widespread clinical use.

[Diagnostic performance of 68GA-PSMA PET/CTin patients with prostate cancer].

INTRODUCTION: and aim. Most of the patients with biochemical recurrence after radical prostatectomy undergo salvage radiotherapy without guidance from imaging. In recent years, there has been an increasing role of Gallium-68 prostate specific membrane antigen (68Ga-PSMA) positron emission tomography/computed tomography (PET/CT) imaging in the management of prostate cancer. This study aimed to investigate diagnostic performance of 68Ga-PSMA PET/CT in patients with biochemical recurrence after radical prostatectomy. MATERIALS AND METHODS: From 2016 to 2017, 19 prostate cancer patients were evaluated by 68Ga-PSMA PET/CT at the Urology Clinic of S.P Botkin City Clinical Hospital; 17 of them had a biochemical recurrence and needed restaging of the disease. The age, prostate specific antigen (PSA) values, therapy at the time of the study, and maximum standard uptake value (SUVmax) were evaluated. RESULTS: The median age of patients was 65 years (interquartile range (IQR) 58.5-70.5), the median total PSA level was 2.36 ng/mL (IQR 1.5-4.19). In 8 of 17 patients, the PSA values did not exceed 2 ng/ml. The median time after radical prostatectomy was 33.2 months. (IQR 12-54.5). Positive PET/CT sites of recurrence were detected in 15 of 17 patients. Nine patients had only one positive site, and in six patients several positive sites were detected. Four patients with PET/CT positive pelvic lymph nodes and/or retroperitoneal space underwent salvage lymphadenectomy. Histological findings confirmed the presence of malignant growth in 3 out of 4 cases. CONCLUSION: 68Ga-PSMA PET/CT is an effective tool for the early detection of oligometastatic lesions in recurrent prostate cancer.

[HYPERBARIC OXYGEN THERAPY IN THE TREATMENT OF MALE INFERTILITY ASSOCIATED WITH INCREASED SPERM DNA FRAGMENTATION AND REACTIVE OXYGEN SPECIES IN SEMEN].

The aim of this study was to explore the potential of hyperbaric oxygenation (HBO) for reduction of sperm DNA fragmentation level and reactive oxygen species (ROS) in semen. The study included 90 men with idiopathic infertility. Patients of the treatment group (n = 60) underwent HBO before the vitro fertilization (IVF) procedure. In the control group (n = 30) IVF was carried out without prior cours of HBO. Sperm DNA fragmentation analysis was carried out using the TUNEL assay, the level of ROS in the ejaculate was measured by chemiluminescence. HBO treatment resulted in a significant decrease in the mean level of sperm DNA fragmentation from 33.2 ± 7.5 to 11.9 ± 5.9%, and the median ROS in sperm from 0.89 to 0.39 mV/s (p < 0.05). In the control group these changes were not statistically significant. Pregnancy after IVF occurred in 63.3% (38/60) of sexual partners of the treatment group men and in 36.7% (11/30) of the control group (p < 0.05). The high efficiency of HBO in overcoming the adverse effects of oxidative stress on sperm parameters allows us to consider it as a promising method for the treatment of men with idiopathic infertility.

[Modified method of retropubic prostatectomy (RMAPE method)].

The article presents the results of the examination and treatment of 125 patients with benign prostatic hyperplasia who underwent surgery in the urological clinic of RMAPE. Retropubic adenomectomy according to the method proposed by the Clinic of Urology and Surgical Andrology of RMAPE was performed in 83 patients, and 42 patients underwent transvesical adenomectomy. In accordance with a number of parameters (timing of surgery, frequency of intra- and postoperative complications, extent of blood loss, duration of bladder drainage, length of hospital stay), a modified method of retropubic prostatectomy demonstrated significantly better results than transvesical adenomectomy.

[Retropubic adenomectomy in patients with a high level of prostate-specific antigen after prostatic biopsy].

Results of examination and treatment were analysed for 58 patients after retropubic adenomectomy performed from February 2008 to June 2010. The examination protocol included assessment of a total score of the scales IPSS and QoL, parameters of uroflowmetry, total PSA, the size of the prostate, number of prostatic biopsies in a high PSA level. The removed adenomatous tissue was examined histologically. By a PSA level, all the patients were divided into 3 groups. Group 1 - 18 patients with a preoperative PSA level above 10 ng/ml, group 2 - 23 patients with a PSA level from 4 to 10 ng/ml, group 3 - 17 control patients with PSA under 4 ng/ml. Mean age of the examinees was 67.7 +/- 7, 68.7 +/- 7.7, 67.9 +/- 8.9 years (p>0.05), respectively. A mean PSA level was 20.9 (10.3-53), 6.6 (4.1-9.9) and 2.4 (1.3-3.9) ng/ml (p<0.01), respectively. A mean size of the prostate was larger in group 1 patients than in the controls: 127.3 (82-185) cm3 versus 100.7 (81-134) cm3 (p<0.05). Median of the number of transrectal multifocal biopsies was 2 (1-7), 1 (1-2) and 0 in groupl, 2 and 3, respectively. Histological examination of the adenomatous tissue detected prostatic adenocarcinoma in 0, 1(4.3%) and 1(5.9%) patients, respectively, while chronic prostatitis at different stages was diagnosed in 6(33.3%), 7(30.3%) and 7(41.2%) patients, respectively. Thus, the above protocol of examination of patients with prostatic adenoma including measurement of a PSA level, conduction of finger rectal examination followed by prostatic biopsy (transrectal saturation procedure is preferable) provides performance of adenomectomy without a risk to miss a clinically significant prostatic cancer even in a PSA level above 10 ng/ml.

[Benefit of primary saturational biopsy in detection of localized prostatic cancer after radical prostatectomy].

We studied diagnostic potential of saturational technique of prostatic biopsy in 1018 males with suspected prostatic cancer (PC). Primary transrectal multifocal prostatic biopsy under ultrasound control was made in all the examinees including 453 procedures with use of saturational technique. The age of the patients varied from 43 to 77 years (median 60 years). A total of 159 patients with diagnosed prostatic cancer have undergone retropubic radical prostatectomy. Saturational biopsy has detected prostatic cancer in 35.1% cases. This technique was employed in hard for PC diagnosis parameters: age median 60 years, PSA 11.9 ng/ml, PSA density 0.23 ng/ml/cm3, prostatic volume 59.7 cm3. The above variant of biopsy detects the highest proportion of localized PC stages, minimal incidence of positive surgical margin, perineural and perivascular invasions, minimal score by Glison/s scale. Thus, the saturational technique of biopsy can be the method of choice in patients under 65 years of age, in a PSA level under 10 ng/ml, PSA density under 0.25 ng/ml/sm3 and prostatic volume over 60 cm3.

[Laparoscopic and microsurgical varicocelectomy: comparison of the results].

Laparoscopic and microsurgical varicocelectomy were compared by clinical and cost efficacy results. Microsurgical subinguinal varicocelectomy was performed in 129 patients, laparoscopic - 167 patients. Median of the patients' age was 27 years (16-38 years). Median of follow-up in microsurgical operation was 26 months (13-60 months), in laparoscopic method - 62 months (28-71 months). By clinical criteria (time of surgical intervention, amount of analgetic drugs in the postoperative period, stay in hospital, rate of varicocele recurrence and postoperative complications), the results of microsurgical varicocelectomy proved significantly better than those of laparoscopic operations. The rate of all complications after microsurgical ligation of the testicular veins was 8 times less than after laparoscopic intervention, the rate of varicocele recurrence - 2.4 times less. Microsurgical operations were financially more effective (by 20%) than laparoscopic varicocelectomy. Thus, microsurgical varicocelectomy is more effective than laparoscopic one both clinically and financially.

[Anastomotic urethroplasty in posttraumatic strictures of bulbomembraneous urethra].

Efficacy of surgical treatment of patients with strictures of the bulbomembraneous portion of the urethra by R. Turner-Warwick in G. Webster modification was studied in 30 patients operated in 2008-2009. Efficacy of the operation was assessed by uroflowmetry and urethrography findings. Follow-up covered 3 to 20 months (median 10 months). Posttraumatic urethral strictures arose after car accident in 89% cases. Mean length of the destruction defect was 2.7 cm (1.5-5.5 cm). Efficacy of surgical treatment reached 96.7%. Erectile dysfunction due to the operation developed in 2 of 23 (8.6%) patients. Thus, urethroplasty by Turner-Warwick in Webster modification is effective and safe in the treatment of posttraumatic strictures of the posterior urethra and can be used widely in specialized centers for urethral surgery.

[The role of combined treatment of prostatic gland after biopsy of the prostate for an elevated PSA level].

Benign prostatic hyperplasia and prostatic cancer have a significant effect of men's health, quality of life and death rate. Recent researches propose algorithms for treatment of benign prostatic hyperplasia which help determine optimal management of the disease using either alpha-adrenoblocker or combined therapy basing on factors of progression risk. Molecular-genetic, biological investigations reveal pathological prosesses leading to onset of the above pathological conditions thus opening prospects for prophylaxis of both benign and malignant prostatic hyperplasia. Further studies will specify efficacy and safety of 5-alpha reductase inhibitors in prevention of prostatic cancer.

[Efficacy and safety of doxazosine in combination with finasteride in the treatment of prostatic adenoma].

Clinical effects and safety of doxazosine + finasteride combination were studied in patients with obstructive and irritative symptoms due to prostatic adenoma (PA). Lower urinary tract symptoms according to IPSS, size of the prostatic gland, Qmax and Qmid, bladder capacity, residual urine volume, blood pressure, PSA level, sexual function, side effects were assessed before and after combined use of the drugs in 30 patients aged 58 to 83 years (mean age 70.5 years). A significant regression of both obstructive and irritative symptoms by IPSS occurred after the treatment. Quality of life has improved. Combined treatment of PA patients has improved quality of life, urination parameters, reduced volume of residual urine. Good tolerance of the treatment was observed. Combined therapy with doxazosine and finasteride can be recommended as a basic scheme of treatment for patients with risk of PA progression.

[Using doxasosine and finasteride combination in the treatment of prostate adenoma].

The study was made in 2005-2006 of efficacy and safety of combined use of doxasosine and finasteride in patients (n = 50, age 53-83) with symptoms of lower urinary tract dysfunction (LUTD) caused by prostatic adenoma. LUTD severity by IPSS, size of the prostate, maximal and mean urinary flow velocity, functional capacity of the urinary bladder, residual urine, blood pressure, a PSA level, sexual function, were assessed at baseline and after the treatment. Side effects were also registered. Combined treatment with doxasosine plus finasteride significantly lowered both obstructive and irritative LUTD symptoms by IPSS, quality of life improved from 3.4 to 2.3 scores (p < 0.01), maximal urinary flow and mean urinary flow velocity increased from 10.2 to 11.6 ml/s and from 5.4 to 6.1 ml/s, respectively, residual urine reduced from 35.2 to 7.7 ml (p < 0.01). The size of the prostate diminished from 55.8 to 46 cm(3) (p < 0.01). PSA decreased from 2.8 to 1.4 ng/ml. Erectile function did not worsen. Thus, the proposed scheme of combined treatment improves quality of life, voiding; lowers residual urine; is well tolerated; can be recommended as a basic scheme of treatment in patients with a risk of prostatic adenoma progression.

[Rehabilitation treatment of inveterate meta-epiphyseal deformities of the radius]. / Vosstanovitel'noe lechenie zastarelykh metaépifizarnykh deformatsii luchevoi kosti.

Unilateral separate anchor--wiring osteosynthesis of the forearm bones has essential advantages over the accepted methods for osteosynthesis of metaepiphyseal fractures of the radius. For adaptation to modern requirements an apparatus is suggested with external fixation of the radial diaphysis and the second metacarpal bone by means of bundles of short Kirschner wires with Y-shaped insertion of the pointed ends. The apparatus provides for longitudinal and transverse movement with fixation of the fragments at any level of the forearm and maintenance of rotational movements and movements at the interphalangeal joints. The method was applied in operations on 18 patients with neglected metaepiphyseal deformities of the radius; the outcome was positive.
