Objectives: Determine the role of perineal ultrasound in the diagnosis of anterior urethral strictures andassessment of peristenotic fibrosis.Material and Method: Thirty healthy adult male and thirty patients with suspected urethral stricture havehad urethral ultrasound after distension of urethra with a normal saline. The thirty patents also underwentretrograde urethrogram (RUG).Results: Average diameters healthy urethra were 11.6 +/- 3.1 mm at penile level, 11.2 +/- 2.7 mm at thebulbar level, and 9.7 +/- 2.88 mm at the bulbomembranous level. The periurethral tissue thickness averaged2.7 +/- 0.5 mm at penile level, from 3.5 +/- 0.65 mm to bulbar level and 3.8±0.6 mm at the bulbomembranouslevel. Ultrasound made the diagnosis of 31 stenosis or 96.87%. On ultrasound, the length of the stenosiswas significantly longer than that seen on retrograde urethrogram with a significant difference between thetwo techniques (P = 0.045). There is also a significant difference in diameter of urethral strictures betweenthe two techniques. The thickness of the periurethral tissue at the level urethral stenosis was more thanthat measured in a healthy zone in all cases, whatever the urethral portion concerned. There was not nocorrelation between periurethral tissue thickness and degree of stenosis.Conclusion: Urethral ultrasound is a method that allows us to make the diagnosis of urethral stricture andto assess periurethral fibrosis. It could validly replace retrograde urethrogram in diagnosing anterior urethralstricture.
