Abstract
Although optical internal urethrotomy is popular among the urologists due to its simplicity and safety, urethroplasty is considered the gold standard treatment for urethral strictures. This study aims to determine the 1-year recurrence rate of urethral strictures after optical urethrotomy and identify predictors of recurrence in a tertiary center in Ethiopia. A prospective observational cohort study was conducted on 80 male patients who underwent optical urethrotomy from November 2019 to August 2020 in a tertiary center in Ethiopia. Logistic regression was used to analyze the association between dependent and independent variables, with a P-value of <0.05 considered statistically significant. The mean and median age (±SD) of patients at the time of the procedure were 54.76 (±14.74) and 58 years with a range [20-78], respectively. Urethral discharge was the most common etiology identified in 39 (48.75%) of patients. Eleven (13.75%) patients had no identifiable etiology for their urethral stricture disease.The majority of patients presented with at least one voiding lower urinary tract symptoms.Sixty-eight (85%) patients out of the total had a single stricture and 12 (15%) had multiple strictures. The location of the stricture was in the bulbar urethra on cystourethrography in 83% of the patients. The 1-year recurrence rate of urethral stricture after optical urethrotomy was 35% in our study.The number of strictures and the presence of hypertension were independent predictors of recurrence of urethral stricture within 1-year after treatment with optical urethrotomy (AOR=15.35, 95% CI: 2.92-80.61, P=0.00; AOR=19.47, 95% CI: 2.11-178.98, P=0.01, respectively). Our study identified that multiple strictures, and the presence of hypertension are associated with an increased recurrence rate in the first postoperative year.
