A New Index of Voiding Dysfunction in Men with Benign Prostatic Hyperplasia Undergoing Transurethral Resection of The Prostate Adds Superior Information to the Traditional Maximum Flow Rate (Q_(max))

摘要

Introduction: To compare Q_(max) and a new index of voiding dysfunction (D) obtained from free flow (FF) and intubated flow (IF) in men before and after trans-urethral resection of prostate (TURP). Material and Methods: Preoperative FF and IF of benign prostatic hyperplasia patients with bladder outlet obstruction were studied for Q_(max) and D, and compared to a series of post-TURP FF in the same patients obtained at interval follow-ups. Analysis was done in a blinded fashion. D was computed with the VBN~R software. Results: From 24 fully studied patients, preoperative D values were similar (p = 0.61) for FF (25.6 +- 7.4) and IF (26.8 +- 7.1).
