Diagnostic Accuracy of Sonourethrography for Anterior Urethral Stricture Taking Retrograde Urethrogram as Gold Standard

Background: Diagnostic accuracy can be improved by using sonourethrography (high-resolution ultrasound) for male anterior urethra. Aim: To find the diagnostic accuracy of sonourethrography for diagnosis of anterior urethral stricture taking retrograde urethrogram as gold standard. Study design: Cross-sectional study. Methodology: Patients (n=102) presented with lower urinary tract symptoms. All enrolled patients had first retrograde urethrogram followed by sonourethrography in the Department of Radiology, Family Care Diagnostic Center Multan-Pakistan for 6 months by keeping confidence interval 95%. Informed consent was taken from all of them. Data analyzed by SPSS 24.0v. Mean +/- SD for age whereas frequency and percentages were given for stricture and site of stricture. Significant p-value was of <= 0.05. Results: The mean age of patients was 37.41 +/- 10.96 years with range (20-66 years). Stricture was observed in 23.5% (24 patients) by SUG whereas it was in 24.5% (25 patients) by RUG. Sensitivity of sonourethrography as a diagnostic tool of anterior urethral stricture among males in our study was 96% whereas specificity was 100%. Conclusion: It gives more accurate information about periurethral fibrosis associated with strictures and other abnormalities thus it can be a useful as well as effective modality for diagnosis of anterior urethral pathologies.
