Urodynamics in Men

There are three main clinical scenarios in which urodynamics (UDS) might commonly be considered in a male patient: lower urinary tract symptoms (LUTS); post-prostatectomy incontinence (PPI); and neurogenic lower urinary tract dysfunction. Male LUTS constitutes one of the bedrocks of urological practice, while PPI is fast emerging as a major part of subspecialist practice in functional urology, due to the increasing use of radical treatments for prostate cancer. The suspicion of Bladder Outlet Obstruction is the most frequent reason for performing UDS in men. Urodynamic studies have provided alternative explanations for certain symptoms, and they have contributed to our understanding of some of the common disorders. For voiding LUTS, the post-operative complaints of slow stream and hesitancy have in the past often led to repeated transurethral resections, leading to increased likelihood of damage to the intrinsic urethral sphincter mechanism.
