Detrusor underactivity in pelvic organ prolapse.

Our study showed a 40.9% prevalence of DU in POP patients. DU was associated with the presence of voiding symptoms and positive PVR. Moreover, cystocele showed to be more severe in DU group. After surgical repair of POP, voiding symptoms of DU patients became equal to non-DU ones, suggesting that obstruction removal might recover DU in these patients.
