Original Article- Female Urology Does Preoperative Urodynamic Testing Improve Surgical Outcomes in Patients Undergoing the Transobturator Tape Procedure for Stress Urinary Incontinence? A Prospective Randomized Trial

Purpose: Urodynamic studies are commonly performed as part of the preoperative work-up of patients undergoing surgery for stress urinary incontinence (SUI). We aimed to assess the extent to which these urodynamic parameters influence patient selection and postoperative outcomes. Materials and Methods: Patients presenting with SUI were randomly assigned to two groups: one undergoing office evaluation only and the other with a preoperative urody-namic work-up. Patients with unfavorable urodynamic parameters (detrusor over-activity [DO] and/or Valsalva leak point pressure [VLPP]＜60 cm H2O and/or maximum urethral closure pressure [MUCP]＜20 cm H2O) were excluded from the urodynamic testing group. All patients in both groups underwent the transobturator midurethral sling procedure. Evaluation for treatment success (reductions in urogenital distress inventory and incontinence impact questionnaire scoring along with absent positive stress test) was done at 6 months and 1 year postoperatively. Results: A total of 72 patients were evaluated. After 12 patients with any one or more of the abnormal urodynamic parameters were excluded, 30 patients were finally re
