A review of the literature involving the rupture or perforation of urinary reservoirs made from the bowel indicates that this complication is perhaps not as rare as commonly perceived. It is a severe complication for which a high index of suspicion needs to be maintained. Physicians attending to patients with such urinary reconstructions should be aware that the diagnosis is often difficult to confirm without resorting to exploratory laparotomy and in particular that a negative cystogram can be misleading. A practical suggestion to help alert these physicians to the possibility of a ruptured urinary reconstruction is that such patients should carry a medical card stating the type of reservoir they have along with their special circumstances. From the reported experiences, it is, however, clear that in carefully selected cases and with vigilant monitoring, some patients may be managed non-operatively. [ABSTRACT FROM AUTHOR]
