Urodynamic evaluation prior to total hysterectomy: indications and incidence of abnormality

Although it is recognized that total hysterectomy may be associated with subsequent urinary symptoms, many women are symptomatic prior to operation. However, only objective rather than subjective analysis can provide an accurate assessment of the preoperative state of the lower urinary tract. This study determined the incidence of preoperative, urodynamically-proven, vesicourethral dysfunction in women undergoing total hysterectomy. The incidence of urinary symptoms in 30 women awaiting hysterectomy was assessed and compared with the urodynamic findings. Sixteen (53%) of these patients had preoperative urinary symptoms, although bladder dysfunction was present in only 8 (27%). The presence of marked urinary symptoms in women awaiting hysterectomy warrants preoperative urodynamic investigation to identify any underlying bladder dysfunction.
