Introduction: There are several options for vessel-sparing anastomotic procedures that allow one to avoid disturbances in the normal blood supply to the spongy body and successfully perform plastic surgery of distal urethral strictures. Aim: To perform a comparative analysis of the effectiveness of reconstructive surgical treatment of strictures of the bulbo-membranous urethra with anastomotic surgery with and without vessel-sparing. Material and methods: A prospective study was carried out on 28 patients with a diagnosis of stricture of the bulbo-membranous urethra who underwent treatment in the period 2012-2018 in the conditions of a urological hospital of Irkutsk City Clinical Hospital No. 1. Anastomotic urethroplasty was performed using one of two methods: with full mobilization of the spongy body bulb and a vessel-sparing method when the spongy body does not intersect. Results: The effectiveness of the classical method of anastomosing EPA-TWW ((excision and primary anastomosis urethroplasty (Turner-Warwick) and excision and Jordan's technique of vessel sparing excision and primary anastomosis)) was comparable with the method of anastomosing without crossing the (spongy body of EPA-J). Postoperative changes in the parameters of the functional status of patients based on the International Prostate Symptom Score (IPSS), International Index of Erectile Function, and Quality of Life were comparable in patients undergoing EPA-TWW and EPA-J. The final data indicate a statistically equivalent risk of developing complications such as urinary incontinence, shortening of the penis, and decreased erectile function. Conclusions: The study did not demonstrate a statistically significant difference in the effectiveness of the treatment and the risks of complications during anastomotic surgery with or without vessel-sparing. However, an unformalized assessment demonstrates the best state of erectile function in patients after vascular-preserving surgery.
Introduction Urethral stricture is a partial or complete narrowing of the urethra, caused by damage to the urethral epithelium. This disease leads to a persistent urination dysfunction, the elimination of which is a difficult task. The aim of this study was to perform a comparative analysis of the immediate and long-term narrowing treatment results of the proximal part of the bulbar and membranous urethral parts using the developed magnifying and anastomotic methods. Material and methods A total of 102 patients with a confirmed diagnosis of stricture of the bulbomembranous urethral part of the urethra who underwent treatment in the urological hospital in Irkutsk City Clinical Hospital No. 1 during the period 2012–2018 participated in this prospective study. Urethroplasty operations were performed in two ways, using the anastomotic and intra-urethral substitution techniques. Through the assessment of preoperative parameters, statistical homogeneity of comparison groups was established. Results The final data analysis showed relapse for 4 patients from Group I and for 2 patients in Group II. The absence of relapse during the entire observation period was equal in both groups and after 2 years amounted to 83.0 ±7.9% in Group I and 92.5 ±5.1% in Group II. Conclusions In both groups, the desired result was achieved – adequate independent urination was restored. The anastomotic method of urethroplasty should be used with caution in patients at risk groups, as well as with the presence of predictors of complications: previous transurethral surgeries on the urethra and prostate, anastomotic urethroplasty, radical prostatectomy. The developed minimally invasive substitution technique has a similar effectiveness with a lower risk of complications.
Introduction. The Buschke — Loewenstein tumour was described for the first time in 1925 as a rare giant condyloma. The main cause of this pathology is the human papillomavirus, which is introduced into the body under certain conditions. This pathogen can be transmitted sexually. The neoplasm is usually localised in the anogenital region. Malignant transformation and its spread to the penis are even more rare.Aims. The Buschke — Loewenstein tumour is a rare pathology, whose course and treatment features are of considerable interest to urologists.Materials and methods. This article presents a clinical case of the malignant giant Buschke — Loewenstein tumour with primary localisation on the anterior abdominal wall and spreading to the genitals of a 42-year-old man without accompanying immunodeficiency or urogenital infections. The anamnesis of the gradually progressive disease in the absence of any treatment was more than 10 years. When preoperative cytological examination of the biopsy did not reveal signs of malignant transformation, the patient underwent simultaneous removal of all neoplasm foci and reconstructive plastic surgery using skin grafts.Results and Discussion. The foci of the tumour were removed entirely without disturbing surgical boundaries. A postoperative histological examination revealed small foci of squamous cell carcinoma in remote tissues. A postoperative observation conducted six months following surgery revealed no signs of recurrence of the disease.Conclusion. Buschke-Loewenstein tumours are rarely accompanied by malignancy. Nevertheless, oncological vigilance forms a necessary element of postoperative procedures. Following removal of a large neoplasm, the choice of reconstructive plastic surgery is of particular significance for postoperative quality of life. For the prevention of relapse, it is advisable to conduct immunotherapy in the postoperative period.
Introduction: The standard treatment for prostate cancer is radical prostatectomy (RP). This surgical technique results in typical complications such as intraoperative blood loss, urethral strictures (vesicourethral anastomosis), urinary incontinence, erectile dysfunction, lymphocele, and the ureter or rectum injury. The study aims to analyze the development of complications after radical prostatectomy. Materials and methods: The article presents a retrospective analysis of clinical cases with an established diagnosis of prostate cancer from 2012 to 2018 in Irkutsk, Russian Federation. During this period, 52 patients met the study criteria. A multivariate analysis established Non-Nerve-sparing RRP (OR-0.9; 95% CI-1.9; -0.07; p=0.035) as a significant incontinence predictor after 2 years. Results: Multivariate analysis also established previous transurethral operations as a significant predictor of the vesicourethral anastomosis stricture (OR 6.09; 95% CI 0.71; 11.4; p=0.026), which indicates a six times risk of developing a vesicourethral anastomosis stricture if the patient already had one or more transurethral surgery. Obesity (OR 0.12; 95% CI 0.03; 0.21; p = 0.008), diabetes (OR 2.3; 95% CI 0.45; 4.2; p = 0.015) and coagulopathy (OR 3.1; 95% CI 0.5; 5.7; p = 0.019) became independent predictors of lymphocele development. Conclusions: The study revealed some new information on the possible predictors of such complications as urinary incontinence in the late period, the lymphocele, and stricture of the vesicourethral anastomosis. Some of the results require further study and confirmation.
