Improved indication and followup in transurethral resection of the prostate using the computer program CLIM: a prospective study.

Analysis of preoperative and postoperative detrusor pressure-flow measurements with the aid of the IBM compatible software package CLIM in 29 patients who underwent transurethral prostatic resection indicated that CLIM supplies reliable obstruction parameters that are recommended for preoperative assessment and postoperative followup, and that approximately a third of the patients who present with prostatism are nonobstructed, suggesting that the indication for transurethral resection of the prostate is over assessed.
