Failure to void after transurethral resection of the prostate and mode of presentation.

Contemporary audits and reviews of outcome after transurethral resection of the prostate (TURP) make little reference to failure to void following catheter removal after this operation. There have been few reports of the likelihood of a successful trial without a catheter after TURP related to mode of presentation. We report the results of a retrospective review of outcome of TURP related to mode of presentation, age, and prostate histologic findings in a consecutive series of patients in a London Teaching Hospital.


A consecutive series of 379 patients (381 TURPs) was reviewed to document the incidence of and risk factors for failure to void following initial trial without a catheter after TURP.


Twelve percent of men failed to void after TURP on the initial trial without a catheter. In those patients presenting with lower urinary tract symptoms, there were no instances of failure to void. Ten percent of patients with acute retention (painful inability to void, urine volume less than 800 mL), 38% with chronic retention (maintenance of spontaneous voiding, bladder volume greater than 500 mL), and 44% with acute on chronic retention (painful retention, urine volume greater than 800 mL) failed to void after TURP. Only 1% of patients required management by long-term catheterization. Failure to void on catheter removal was not related to age or prostate histologic findings.


Bladder volume at initial presentation in patients with urinary retention provides important information about the likelihood of re-establishing spontaneous voiding catheter removal following TURP. Patients should be warned that there is a significant chance of failure to void after TURP, the exact risk depending on their mode of presentation, but that most will ultimately not require a permanent indwelling catheter.
