The significance of uninhibited detrusor contractions in prostatism.
In an attempt to identify preoperatively patients who will not benefit from prostatectomy, 84 patients with prostatism about to undergo transurethral resection of the prostate were evaluated prospectively with preoperative and postoperative symptom analysis and urodynamic examination, including cystometrograms. Of the patients 67 were followed at 3 months and 54 again at 12 months. Preoperatively, 65 per cent of the patients had uninhibited detrusor contractions, while 38 had persistent postoperative uninhibited detrusor contractions at 3 months. Patients in whom uninhibited detrusor contractions persisted postoperatively more often had unacceptable postoperative symptoms. Of the patients 13 per cent believed the symptoms to be the same or worse at 3 and 12 months. The incidence of uninhibited detrusor contractions in these patients was 57 and 71 per cent, respectively. While this finding suggests that persistent postoperative uninhibited detrusor contractions are associated with an unfavorable surgical outcome, we could not predict which patients would have uninhibited detrusor contractions following prostatectomy by use of preoperative cystometric findings together with detailed symptom analysis. Thus, we failed to define a role for preoperative cystometric screening of patients with prostatism.
