The role of preoperative urodynamics in urogynecologic procedures.

Urodynamic studies refer to any tests that provide objective information about lower urinary tract function with the goal of evaluating bladder and urethral function. Pre-operative urodynamic testing is commonly performed prior to urogynecologic procedures for urinary incontinence and pelvic organ prolapse. Although the utility of preoperative urodynamics testing before urogynecologic procedures have been challenged in the literature, the preoperative utilization of urodynamic testing in women with complex voiding dysfunction or associated conditions such as prolapse or urethral diverticulum is still considered important for surgical planning and pre-operative counseling.
