Short-term recurrence rate of male urethral stricture and its predictors after treatment with optical internal urethrotomy: Prospective Cohort Study at a tertiary center in Ethiopia.

Background: 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. Methods: 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. Results: 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). Conclusions: Our study identified that multiple strictures, and the presence of hypertension are associated with an increased recurrence rate in the first postoperative year.

Unilateral Giant Hydronephrosis Secondary to Ureteropelvic Junction Obstruction in a Middle-Aged Woman.

BACKGROUND: Giant hydronephrosis is a rare urologic problem defined as a collection of more than one liter of urine in the collecting system. The radiologic appearance may mimic benign cystic disease of the kidney. We report a case of giant hydronephrosis in a 32-year-old female who presented with progressive abdominal swelling of two-year duration, caused by ureteropelvic junction obstruction with more than nine liters of urine in the collecting system. CONCLUSION: Giant hydronephrosis is a rare differential diagnosis for cystic intra-abdominal mass in adults with progressively increasing abdominal swelling. CT and MRI are important in confirming the diagnosis by localizing the origin of the swelling. Management depends on the underlying cause and appearance of the diseased kidney.
