title: Voiding function in patients with the prune-belly syndrome after Monfort abdominoplasty.
abstract: OBJECTIVE
  We reviewed our experience with patients with the prune-belly syndrome who had undergone Monfort abdominoplasty to assess whether our clinical impression of improved voiding efficiency could be demonstrated objectively.
  
  
  METHODS
  From 1990 to 1993, 12 patients with the prune-belly syndrome underwent Monfort abdominoplasty with or without concomitant genitourinary reconstruction. All patients completed questionnaires on voiding before and after abdominoplasty, incontinence, bladder sensation, urinary flow, history of urinary tract infections and the ability to defecate. Urodynamic testing was performed in 8 patients before and after abdominoplasty.
  
  
  RESULTS
  Subjective changes that occurred after abdominoplasty included resolution of or less double voiding in 9 patients, improved urinary continence in 7, improved bladder fullness sensation in 11, improved urinary flow in 10 and improved defecation in 5. The incidence of urinary tract infections decreased from a preoperative average of 5.7 per patient per year to 1.2 per patient per year postoperatively. Urodynamics demonstrated no significant changes in the measured urinary flow, capacity or maximal detrusor pressure. Compliance decreased on average but it remained in the compliant range. However, post-void residual volumes did significantly decrease from a preoperative average of 40.3% of bladder capacity to 13% after abdominoplasty. If the 5 patients who underwent concomitant urinary reconstruction were excluded, the reduction in average post-void residuals remained approximately the same, which was 40% of bladder capacity preoperatively to 14.3% after abdominoplasty. These data suggest that abdominoplasty alone was responsible for improved micturition.
  
  
  CONCLUSIONS
  In addition to the cosmetic benefits and exposure provided for genitourinary reconstruction Monfort abdominoplasty seems to improve voiding efficiency.
