Twenty‐seven patients with symptomatic bladder outlet obstruction secondary to benign prostatic hyperplasia (BPH) were evaluated preoperatively by standard urodynamic investigation and by rapid filling cystometry (RFC). Rapid filling cystometry was performed by injecting a maximum of 120 ml saline into the empty bladder through a catheter at a constant flow rate over 4 seconds. Twenty‐three patients were reexamined 3 months after transurethral prostatic surgery. Three patients had not improved symptomatically. None of these three had uninhibited detrusor contractions (UDC) by RFC, but medium filling cystometry revealed UDC in 2 of the patients, both pre‐ and postoperatively. Rapid filling cystometry, as used in this study, correlated poorly with medium filling cystometry and failed to identify the patients that will not benefit from prostatic surgery due to persistent postoperative UDC.
