Bladder wall mechanics and micturition before and after subtotal and total hysterectomy

Twenty-two women were assigned at random to subtotal (n = 11) or total (n = 11) hysterectomy. The frequency of micturition was recorded and urodynamic investigation was performed before, and 6 weeks and 6 months after the operation. After hysterectomy the frequency of diurnal micturition decreased and the urethral conductance increased in all patients. After total hysterectomy an increased bladder volume was found. The two operative methods did not differ with respect to pre- and postoperative changes of urinary frequency or urodynamics. The bladder function was not altered by either operation.
