Changes in bladder capacity under anesthesia at each surgery (A) and its ratio to the capacity at the first procedure (B). Bladder capacity under anesthesia at each surgery was gradually decreased although there were no significant differences in the comparison of bladder capacity at different time points of surgical procedures. Meanwhile, the ratio of bladder capacity to the capacity at the first procedure was significantly decreased to 80% at the fourth surgery. *P<0.05 vs. the first procedure.
