Our study aims to investigate the incidence of UI among patients undergoing different procedures for BPH.</p><p><strong>Methods: </strong>A retrospective analysis was conducted using a large national database, containing patient records between 2011 and 2022. The most employed surgical procedures for BPH were considered, including TURP, Transurethral Incision of the Prostate (TUIP), Holmium/Thulium Laser Enucleation of the Prostate (HoLEP/ThuLEP), Open Simple Prostatectomy (OSP), minimally invasive simple prostatectomy (Lap/Rob SP), Photoselective Vaporization of the Prostate (PVP), Prostatic Urethral Lift (PUL), Robotic Waterjet Treatment (RWT - Aquablation^®), Water Vapor Thermal Therapy (WVTT - Rezum^®) and Prostatic Artery Embolization (PAE). Rates of any type of UI, including stress UI (SUI), urge UI (UUI) and mixed UI (MUI) were assessed.

Open urethroplasty is the gold standard treatment. However, stricture recurrence (SR) remains a current subject of concern. The aim of the present review is to provide an updated literature summary on surgical urethroplasty techniques for bulbar US and prognostic factors for SR, comparing the different approaches. For short strictures, excision and primary anastomosis (EPA) is the preferred option, with success rates exceeding 90%. Substitution techniques are usually required for longer strictures (>2-3cm). Buccal mucosa graft (BMG) remains the first choice as it complies with ideal features, with no significant differences regarding the site of graft implantation. Stricture length, time since urethroplasty and number of previous urethral interventions are risk factors for failure. Also, surgeon's experience affects technique selection and future outcomes. There seems to be consensus on a higher SR rate following substitution techniques compared to EPA, which appears to be influenced by the stricture length, usually longer in the former group. Furthermore, there is a trend in favor of endoscopic management of SR, except for long and complex recurrences where grafts should be used. In conclusion, multiple urethroplasty techniques are available and selection must be carefully individualized, focusing on stricture characteristics, patient's history, and surgeon's experience. Well-designed studies with clear definitions and follow-up protocols are still necessary to develop standardized guidelines on the management of bulbar US.</p>","PeriodicalId":53228,"journal":{"name":"Minerva Urology and Nephrology","volume":" ","pages":"563-569"},"PeriodicalIF":4.9,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141753378","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
