Background: Male urethral stricture is a common and challenging urological disease.Optical urethrotomy is a promising treatment option for short-segment bulbar strictures. The present study aimed to predict the outcome of optical internal urethrotomy for short-segment bulbar urethral strictures by measuring the percentage of lumen narrowing at the stricture site using retrograde urethrogram (RGU). Methods: This prospective observational study was conducted at King George Hospital/Andhra Medical College, Visakhapatnam, from January 2019 to December 2020. The study involved analysis of radiological films of patients with short bulbar urethral stricture who underwent optical internal urethrotomy. A high-quality RGUmeasuredthe site of the maximal lumen narrowing andpatients were followed for symptom recurrence. Results: The study included 40 patients with a mean age of 46.61 years. Most patients fell into the age groups of >30-≤40 and >40-≤50 years (30% each). Idiopathic strictures were the predominant etiology in 45.0% of patients. Overall, 16 patients achieved successful treatment, while 24 experienced treatment failure. The lumen narrowing of ≤70% within both RGU (68.18% vs 31.82%) and outcome (93.75% vs 29.16%) was significantly higher among patients with treatment success than those with treatment failure (P<0.0001). Conversely, the lumen narrowing of >70% within both RGU (94.5% vs 5.5%) and outcome (70.83% vs 6.25%) was significantly higher among patients with treatment failure than those with treatment success (P<0.0001). Conclusion:The percentage narrowing of the urethral lumen at the stricture site serves as a valuable predictor of the outcome of optical internal urethrotomy.
