There has been anecdotal evidence that patients undergoing abdominoplasty have had improvements in their voiding dysfunction postoperatively. To date, there have been three case reports in which correction of urinary incontinence (UI) following abdominoplasty has been described (Widgerow 1992, Mast 1999 & Guneren 1999). However no study has evaluated the influence of abdominoplasty on voiding dysfunction. This prospective study aimed to confirm the anecdotal reports, objectively substantiate the subjective improvements and attempt to explain why abdominoplasty may result in resolution of UI.Methodology: Twenty consecutive abdominoplasty patients were assessed by a standardised questionnaire pre and postoperatively. Pelvic floor measurements (resting tone & maximal strength) were also obtained. Procedures included either radical or sub‐umbilical abdominoplasty.Results: The study involved 20 patients aged between 25 and 62 years. 14 were found to have stress urinary incontinence. Postoperatively 10 patients described improvement in their symptoms, 3 had no change, whilst 1 patient had worsening of her symptoms. 16 patients were found to have improved pelvic floor strength, 2 remained unchanged and 2 had reduced pelvic floor strength.Conclusion: Improvement in UI following abdominoplasty was clearly demonstrated. We suggest that this may be attributable to a better bladder neck and urethral angle position, as well as increased pelvic floor tone secondary to reflex contraction of the pelvic floor muscles. Patients reporting UI should be carefully assessed preoperatively. Aim for the future is to predict who simply requires an abdominoplasty to solve the problem and who requires a combined procedure with a urologist.
