[Traumatic injuries of the urethra: an echographic study].

: US in the lower urinary tract usually explores the bladder and the prostatic urethra. In this study we used US instead of x-rays to visualize the remaining urethra in 42 patients. US was useful in the presence of urethral trauma. The site and extent of injury, particularly peri-urethral lesions (hematomas, urinary collection and abscesses in relation to the urethra) were observed. Ultrasound's efficacy and reproducibility were also useful in post-operative follow-ups.
