Abstract
During the last 7 years we have managed more than 100 cases of bladder rupture, the majority owing to blunt trauma. Of these ruptures 62 were extraperitoneal, including 59 (95 per cent) with associated pelvic fractures. Twelve patients had an associated urethral injury and 5 had a concomitant intraperitoneal bladder rupture. Complex injuries with extravasation outside the confines of the perivesical space were noted in 42 per cent of the patients. Extravasation extended into the scrotum, thigh, anterior abdominal wall and penis, and through the obturator foramen. The 41 patients who were treated with catheter drainage alone did well.
