Urodynamics of post-radical perineal prostatectomy incontinence

A series of post-radical perineal prostatectomy patients was studied by carbon dioxide cystometry. Of 30 patients questioned 17 were available for urodynamic assessment. All patients had shortened functional urethral lengths and decreased maximal closure pressures and incontinent patients had changes in the standing position. A review of the pertinent literature is presented. We believe that such studies in these patients can be clinically contributory and are of academic interest but history and cystourethroscopy remain more important in the over-all patient evaluation and care. With the ever-growing enthusiasm for urodynamics it is important to reveal its limitations as well as its benefits.
