Abstract

Objective: To determine if urodynamic findings other than high-pressure voiding influence the decision to perform a transurethral resection of prostate (TURP).

Methods: Four clinical scenarios were created featuring a healthy 65-year-old man. An electronic survey was distributed to members of the International Continence Society and the Society for Urodynamics, Female Pelvic Medicine and Urogenital Reconstruction.

Results: Eighty-six urologists responded (median age was 45-54 years, 62% described their practice as academic). Scenario 1: an incidental residual urine >1 L with detrusor underactivity. The majority (76%) would offer a TURP; however, the estimated chance that the residual volume would improve was only 57%. Scenario 2: retention with detrusor overactivity but no voluntary voiding contraction. The majority (72%) would offer a TURP; however, the average chance quoted that he would void was only 48%. Scenario 3: catheter-dependent retention and an underactive detrusor. The majority (89%) would offer a TURP; however, the average chance quoted that he would void was only 53%. Scenario 4: a man with only frequency and urgency, but urodynamic bladder outlet obstruction. The majority (90%) would offer him a TURP; however, the average chance that his frequency and urgency would improve was only 64%, and the average estimated postoperative risk of urgency incontinence was 33%. Willingness to offer TURP did not correlate with physician characteristics.

Conclusion: Urodynamic findings other than bladder outlet obstruction were associated with modest perceived outcomes after TURP; however, despite this, urologists are still willing to offer this intervention.
