CONTEXT: Urethral stricture is a pathology involving the anterior urethra. The parameters to the surgical approach are precise measurement of stricture length and spongiofibrosis. Retrograde urethrography (RGU) is considered as the gold standard investigation. Its limitations are poor definition of stricture length and the detection of spongiofibrosis. Sonourethrography (SUG) detects stricture and accurately measures length and spongiofibrosis. AIM: The aim of this study is to compare the efficacy of SUG in the evaluation of anterior urethral strictures. SETTINGS AND DESIGN: The study design involves hospital-based 1-year observational study. SUBJECTS AND METHODS: One-year prospective observational study was conducted in the Department of Radio-Diagnosis at the KLE'S Dr. Prabhakar Kore Hospital and MRC, Belagavi. Thirty patients underwent RGU and SUG. Sensitivity, specificity, positive, and negative predictive values of SUG were calculated. Unpaired t-test was used to determine the length of the anterior urethral stricture. The values were compared with RGU and intra-operative results. The percentage of patients detected to have spongiofibrosis was computed. STATISTICAL ANALYSIS USED: Mean, standard deviation, and unpaired t-test were used for statistical analysis. RESULTS: The sensitivity and specificity of sonourethrogram as compared to retrograde urethrogram was found to be 92% and 100%, respectively, with positive and negative predictive values of 100% and 71.43%, respectively. Intra-operative stricture length correlated better with SUG with the determination of spongiofibrosis being an advantage. CONCLUSION: RGU is the best imaging modality, but SUG also provides similar results with benefits such as precise measurement of stricture length and degree of spongiofibrosis.
