title: Factors affecting transient urinary retention after transobturator tape mid-urethral sling surgery for female patients with stress urinary incontinence: a single center experience.
abstract: OBJECTIVE
  To identify the incidence and potential risk factors affecting postoperative transient urinary retention (TR) with transobturator tape (TOT) mid-urethral sling surgery for female patients with stress urinary incontinence (SUI).
  
  
  METHODS
  We reviewed the medical records of 305 patients with SUI who underwent the TOT procedure. Postoperative TR was defined as follows: (1) patients had still voiding difficulty after removing the Foley catheter postoperatively and (2) straining pattern of postoperative voiding with the post-void residual urine volume (PVR) larger than 100mL during 1st or 2nd trial of self-voiding and (3) these voiding problems are resolved within 48 h without any special treatment. The Foley catheter was removed routinely on the first postoperative day. Age, previous pelvic surgery history, co-existence of cystocele, number of vaginal deliveries and all urodynamic parameters were analyzed and compared between the TR group and control group.
  
  
  RESULTS
  The incidence of TR was 9.5%. Comparative analysis revealed concomitant prolapse surgery including anterior and posterior repair, Valsalva leak point pressure and preoperative PVR. In multivariate analysis, preoperative PVR proved to be a potential risk factor for TR.
  
  
  CONCLUSIONS
  TR was not a rare postoperative complication after TOT procedures. Potential risk factors for transient retention include preoperative PVR.
