The Treatment of Traumatic Urethral Strictures by One-stage Urethroplasty Techniques (Film)

Introduction. The problem of extended urethral strictures treatment remains relevant due to the complexity of the supervision of such patients and the high frequency of disease recurrence after surgical treatment.Purpose of the study. Evaluation of the effectiveness of one-stage buccal urethroplasty according to the Kulkarni technique using two flaps for extended anterior urethral strictures.Materials and methods. The study included 18 men with an extended anterior urethral stricture, who underwent buccal urethroplasty by perineal access using the Kulkarni dorsolateral onlay technique using two flaps from January 2018 to March 2020, and a postoperative follow-up period of at least 6 months. The study was prospective. Control examination was carried out 3, 6, 12, 18 and 24 months after surgery. The criteria for the recurrence of urethral stricture were the presence of complaints of deterioration in the quality of urination in combination with a decrease in the maximum urinary flow rate of less than 12 ml/sec and the presence of residual urine in an amount of more than 100 ml, as well as the need to perform any surgical intervention to restore the normal passage of urine.Results. The age of the patients ranged from 32 to 72 years (median 58 years). The length of the stricture ranged from 6 to 11 cm (median, 8 cm). The stricture was localized in the penile segment in 11 (61.1%) cases and the penile and bulbar urethra in 7 (38.9%) cases simultaneously. An iatrogenic cause of urethral stricture occurred in 11 (61.1) patients, idiopathic in 5 (27.8%) patients and inflammatory in 2 (11.1%) patients. The stricture was primary in 12 (66.7%) cases and recurrent in 6 (33.3%). Spontaneous urination was preserved in 6 (33.3%) patients, cystostomy existed in 12 (66.7%) patients. The follow-up period after surgery ranged from 3 to 24 months (median - 12 months). Recurrence of urethral stricture was noted in 3 (16.7%) cases. The use of this technique for recurrent forms of the urethral stricture (recurrence after the previous urethroplasty) is the most significant risk factor for treatment failure. 1 (5.6%) case of erectile dysfunction and stress urinary incontinence has taken place of the late postoperative complications.Conclusions. The Kulkarni operation using two buccal flaps for extended strictures of the anterior urethra allows to achieve high rates of efficacy and safety of a treatment, however, the risk of failure increases significantly when used for the treatment of recurrent types of strictures.

Introduction. Extended spongy urethral strictures require the use of plastic surgery techniques. In most cases, a one-stage urethral repair can be performed. However, staged urethroplasty and permanent urethrostomy are important in patients with extremely complex urethral strictures. Purpose of the study. To determine the clinical features of spongy urethral strictures, which cannot be cured by one-stage urethroplasty, but are subject to multistage plastic or permanent urethrostomy. Materials and methods. The study included 158 patients who underwent surgery for urethral strictures in 2010 − 2019. Inclusion criteria: spongy urethral strictures requiring staged urethroplasty or permanent urethrostomy. Exclusion criteria: age<18 years, proximal urethral strictures, urethra-vesical anastomosis and bladder neck stenosis, previously untreated congenital anomalies (hypospadias and epispadias), and history of any other urethral surgery not meeting the inclusion criteria. Results. The age of the patients ranged from 18 to 88 years. Iatrogenic (34.8%) and inflammatory (32.3%) urethral lesions predominate in the structure of etiological factors with the most common penile localization of narrowing (43.7%). The length of strictures in half of the patients exceeds 6 cm; a quarter of the sample has subtotal and total spongy urethral lesions. The proportion of recurrent urethral strictures is 56.3%. The average duration of the urethral stricture disease reaches 8 years. In 61.3% of cases, the disease is accompanied by complications from both local tissues and organs of the urinary and reproductive systems. Conclusion. Clinical evaluation of patients with spongy urethral strictures requiring multi-stage urethroplasty or permanent urethrostomy reveals a particular severity of urethral stricture disease. This category of patients has a high risk of unsuccessful outcomes with one-stage surgery. In these cases, patients require a multi-staged urethroplasty or a permanent urethrostomy.

Flap Repairs

Background: Reconstructive approaches for distal urethral strictures range from simple meatotomy to utilizing grafts or flaps depending on the etiology, length and location. We describe a contemporary cohort of distal urethral strictures and report a surgical technique termed distal one-stage urethroplasty developed to address the majority of distal urethral strictures encountered. Methods: Thirty-four patients were included. The mean age was 56.7 years (range 15.7–84.9 years), the mean stricture length was 1.1 cm (0.5–1.5) and the mean follow-up was 42.5 months (28–61.3). Results: The vast majority of distal strictures (27/34 (79.4%)) were treated with our hybrid one-stage approach combining a distal urethral reconstruction with excision of the scar tissue without the need to use grafts or flaps. The average stricture length was 0.68 cm and average operative time was 24.43 min. Post-operative spraying was reported in a minority of patients (4/27 (14.8%)). The length of stricture and surgery were significantly longer in those 7/34 (20.6%) patients in whom grafts or flaps were used (2.88 cm and 154.8 min, respectively, p < 0.001 for both when compared to the hybrid one-stage approach). We noted 6/34 (17.6%) recurrences of distal urethral strictures, all of which were treated successfully with graft and flap repairs. Conclusions: The vast majority of distal urethral strictures are amenable to a distal one-stage urethroplasty, avoiding the use of grafts and/or flaps while achieving reasonable outcomes. This limited approach, at least initially, is associated with shorter operative time and time of catheter placement and avoids morbidity associated with graft or flap harvesting. Spraying of urine is seldomly encountered and comparable to other approaches addressing distal urethral strictures.
