[Urethroplasty technological changes for the treatment of male urethral stricture]

Urethroplasty is an important method to treat male urethral stricture. Nowadays, urethroplasty mainly includes two types: anastomotic urethroplasty and substitution urethroplasty. Anastomotic urethroplasty mainly includes primary anastomosis urethroplasty and non-transecting anastomotic urethroplasty. Substitution of urethroplasty mainly includes staged urethroplasty and one-stage urethroplasty. Substitution materials always are chosen by pedicle skin flap and free mucosal graft. Anastomosis urethroplasty has shown good results in short bulbar urethral stricture and posterior urethral stricture after pelvic fracture. Among them, non-transecting anastomosis urethroplasty has become a new surgical method for iatrogenic, single, short or non-occluded stenosis. At present, the one-stage substitution urethroplasty is the most widely used. However, there are still many complicated cases that must be solved by staged urethroplasty. Pedicle skin flap and oral mucosa are widely used as substitutes at present. How to select the best surgical procedure and substitute materials individually would be the problem worthy of attention in the future. Accumulating more long-term follow-up data is helpful for objective comparison of various surgical procedures and grafts.

[Application of patient-reported outcome measures in the diagnosis and treatment of male urethral stricture: An update]

Urethral stricture is a common and recurrent male disease, and its treatment has been shifted from endoscopic management to urethroplasty, which has greatly improved the success rate of treatment. However, patients and doctors often have different evaluations of the sexual function and lower urinary tract symptoms after urethroplasty, which has attracted the attention of researchers. In recent years, specific questionnaires or scales have been used to evaluate the effects of preoperative and postoperative treatment, laying more stress on the subjective feelings of the patients. Such questionnaires or scales are called patient-reported outcome measures (PROM). This article reviews the application of PROM in recent studies of urethral stricture, focusing on sexual function and lower urinary tract symptoms, aiming to provide some reference for the development and application of PROM in the diagnosis and treatment of male urethral stricture.
