Abstract

Introduction. Circumcision is one of the most common surgical procedures for men. WHO programs aimed at reducing HIV transmission have led to the development of various circumcision devices designed to standardize surgical techniques, reduce operating time and the number of complications.Objective. To examine available data on the efficacy and safety of different methods of device-based circumcision.Materials & methods. The results of a search in scientific databases such as eLibrary and PubMed were analyzed using the keywords: "circumcision", "circumcision device", and "phimosis". The search was conducted without regard to date or language of publication. After reviewing the literature, 25 articles were selected that best reflect the topic of device-assisted circumcision for further analysis.Results. Device-based circumcision can significantly reduce surgical time, regardless of the type of device used. Device-based circumcision is the safe treatment method; however, it may have a higher incidence of adverse events compared to the standard circumcision technique. The use of self-suturing devices is preferred over ring devices due to fewer complications, better cosmetic results, and greater patient satisfaction. The article is supplemented with a description of the surgical technique of various options for device-based circumcision.Conclusion. Device-based circumcision is effective and safe treatment method on an outpatient basis, which successfully competes with conventional circumcision of the foreskin.

Abstract

Varicocele is one of the most common problems in modern reproductive medicine. The incidence of varicocele in the structure of the general male population is 15%, 40% of which have problems with fertility. Among the causes of male infertility, varicocele ranks second after idiopathic, thus being the most common curable cause of male infertility. While researching the pathophysiological mechanisms of infertility in varicocele, the question of the reasons for the varicocele relapses, both after surgical and endovascular methods of treatment remains open, as well as the tactics of managing such patients. The review aimed to systematize knowledge about the problem of recurrent varicocele, to analyze the frequency and etiology of relapses after various methods of primary treatment, as well as to select the optimal diagnostic and treatment option for varicocele recurrence.

Abstract

INTRODUCTION The recurrent course of the disease stricture is a complex problem for both the patient and the operating surgeon and requires an integrated approach to treatment only in expert centers. PURPOSE OF THE STUDY To assess the effectiveness of methods of surgical treatment of recurrent urethral strictures. MATERIALS AND METHODS At the University Clinic of Urology, Russian National Research Medical University named after N.I. Pirogov, an analysis of the results of surgical treatment of patients with recurrent urethral stricture from 2012 to 2020 was carried out. This work included patients who underwent surgical treatment for recurrent urethral stricture. A total of 120 men were involved in the work. The median length of the stricture was (min-max) - 2 (0.5-16 cm). In 95 (79.1%) patients, stricture of the bulbous urethra, in 15 (12.5%) - in the penile urethra, in 2 (1.7%) patients had panurethral stricture, in 6 (5.0%) - membranous urethra and in 2 (1.7%) - meatus. All patients were divided into two groups: with recurrent urethral stricture after primary DVIU (group I, n=77) and recurrent urethral stricture after primary urethroplasty (group II, n=43). Depending on the method of surgical treatment of recurrent urethral stricture, patients in group I were divided into 4 subgroups. Repeated DVIU + 3 months Autocatheterization - 16 (20.8%) patients; End-to-end urethroplasty - 37 (48.1%) patients; one-stage urethroplasty with a buccal graft or skin graft - 22 (28.6%) patients; multistage urethroplasty or perineostomy - 2 (2.5%) patients. Group II was also divided into 4 subgroups. DVIU - 17 (39.5%) patients; end-to-end urethroplasty - 6 (13.9%) patients; one-stage urethroplasty with a buccal graft or skin graft - 9 (20.9%) patients; multistage urethroplasty - 11 (16.7%) patients. Median Qmax - 4.68 ml/sec. Preoperative cystostomy was observed in 31 (25.8%) patients. RESULTS The median follow-up was 24 months (range 12 to 76 months). Depending on the method of surgical treatment of recurrent urethral stricture, the effectiveness of DVIU according to strict indications was 75.7%. End-to-end urethroplasty showed an efficiency of -88,4%. One-stage augmentation urethroplasty had an efficiency of -77,4%, and multi-stage urethroplasty showed an efficiency of 84.6%. The IPSS value for the observation period 2 years was 2.6+/-0.9 points. The average value of Qmax at the time of observation was 19.4+/-7.1 ml/sec. The effectiveness of the treatment was 82%. During the follow-up period, a relapse was noted in 22 (18%) patients. The overall effectiveness of the treatment of recurrent urethral stricture, taking into account the treatment of recurrent cases of disease recurrence, was 97.5%. CONCLUSIONS Urethroplasty is the treatment of choice for recurrent urethral strictures, which has been shown to be more effective than DVIU. However, the results of urethroplasty for recurrent strictures are worse than for primary strictures.
