Urodynamic evaluation of lower urinary tract function in relation to total hysterectomy

Although many women relate the onset of urinary symptoms to the operation of simple hysterectomy, many also have symptoms prior to surgery. Prospective study is therefore the most valid method of objective analysis of the effects of this operation upon micturition. To determine whether total hysterectomy is associated with increased postoperative vesicourethral abnormality, the incidences of urinary symptoms and urodynamic abnormality were assessed pre and postoperatively in 36 women undergoing hysterectomy. Preoperative symptoms were present in 58.3%, although urodynamically proven dysfunction was found in only 38.9%. After hysterectomy, 75% of women were symptomatic with a further 30.6% developing a urodynamic abnormality. The operation of total (simple) hysterectomy is associated with a significant increase in the subjective and objective incidence of vesicourethral dysfunction.
