Introduction. Many methods have been proposed for the surgical treatment of varicocele, the most of which is of historical significance. At present, there is no consensus in favor of one or another method of surgical treatment of varicocele, which determines the relevance of further research.Objective. To evaluate the effectiveness of a new minimally invasive method of surgical treatment of varicocele using the author's method.Materials & methods. The study enrolled 763 patients aged 18 – 46 years (mean age 26.3 years) with varicocele who underwent testicular vein subinguinal ligation according to the author's technique. Inclusion criteria: varicocele grades 1 – 3, aged ≥ 18 years, semen abnormalities according to semen analysis and dilated spermatic cord veins according to ultrasound, retrograde blood flow according to Doppler ultrasound. Exclusion criteria: previously operated patients with recurrent varicocele, patients with May-Thurner syndrome and bilateral varicocele. The examination included eight control points: before surgery and 3, 6, 12, 24, 36, 48, and 60 months after surgery. Physical scrotal examination with Valsalva test, semen analysis, and Dopper scrotal ultrasound were performed at the control dates.Results. The average surgery time was 15 min (10 – 30 min). All patients were discharged 1 to 2 days after surgery. At follow-up for 60 months, patients showed improvement in spermatogenesis / or no progression of semen abnormalities during follow-up after surgery based on clinical, laboratory and instrumental studies (semen analysis, ultrasound / Doppler ultrasound); no data on testicular hypotrophy, hydrocele were revealed. A scrotal haematoma was detected in one patient in the early postoperative period. Recurrent varicocele (1.4%) was detected in 11 patients during the follow-up period.Conclusion. The technique is effective, easily reproducible, characterised by a low rate of recurrence and postoperative complications.

Introduction. Urethroplasty is the “gold standard” treatment of urethral stenosis. However, often in connection with old and senile age, as well as due to the presence of concomitant diseases, it is not possible to carry out urethroplasty due to its certain invasiveness. In such cases, one of the methods of treatment is the installation of a urethral stent. But this method has not found practical application due to the frequent migration of stent and the high frequency of its incrustation. The approach developed by us avoids stent migration.Purpose of the study. To evaluate the immediate results of the placement of a urethral stent with fixation through the perineum.Materials and methods. A total of 18 patients with urethral stenosis aged 68 to 84 years have been operated on since February 2019. Ten patients had stenosis of the urethrocystoneoanastomosis after radical prostatectomy, 6 patients had iatrogenic stenosis of the prostatic urethra, 1 patient had post-radiation stenosis of the bulbo-membranous urethra. All patients in the preoperative and postoperative periods underwent: IPSS-QoL questioning, uroflowmetry, bladder ultrasound with residual urine volume evaluation, urethroscopy, ascending and micturition urethrocystography. The first stage was an internal optical urethrotomy according to the standard technique. Then, a urethral stent was installed in the area of dissected stenosis. The second stage was an incision in the perineum, the urethra was isolated, and under optical control, through the perineum, the stent was fixed to the urethra with non-absorbable suture material. The stent was removed endoscopically after 6 months.Results. The median surgery duration averaged 45 minutes. Patients were discharged 2 to 3 days after surgery. The maximum observation period was 20 months. During the observation period, not a single case of stent migration was recorded. All patients showed a persistent increase in Qmax and no residual urine. Six patients had a stress component of urinary incontinence, 4 patients had total urinary incontinence. According to control urethrocystoscopy 6 months after stent removal, clinically insignificant urethral stenosis was noted in all patients. In all cases, moderate signs of stent encrustation were identified. Dysuric phenomena disturbed 5 patients, who were stopped by rectal suppositories with NSAIDs, as well as taking herbal uroseptics. The data from the IPPS-QoL questionnaires confirm the positive effect of the treatment.Conclusions. Temporary placement of a urethral stent for urethral stenosis is an effective minimally invasive treatment. The technique of fixation through the perineum allows preventing migration in all cases. This approach to treatment significantly improves the quality of life of patients who were contraindicated for urethroplasty for one reason or another. However, the technique requires longer observation and analysis.
