Injury to the urinary or gastrointestinal tract is rare in the course of cesarean section. The most common is laceration of the bladder with an incidence of 2 in 1000 cesarean sections. Less common are injuries to the colon with the least common being ureteric injury. In all cases, a history of previous surgery, usually prior cesarean section, is the most significant risk factor. However, any condition that predisposes to adhesion formation may be a factor.
