INTRODUCTIONWe aimed to evaluate the local incidences of hydronephrosis and renal impairment in the presence of severe uterovaginal or vault prolapse, and determine whether treatment by surgery or ring pessary resulted in the resolution of hydronephrosis in these patients.

METHODSThis was a retrospective case study of 121 patients who presented with severe uterovaginal or vault prolapse. All patients who had fourth degree uterovaginal or vault prolapse, and underwent renal ultrasonography and renal function blood tests were included in the study. Follow-up imaging for hydronephrosis was performed to determine the outcome after patients received treatment.

RESULTSThe mean age of the study population was 66.1 years. The overall incidence of hydronephrosis was 20.6%. The incidence of hydronephrosis in patients with severe vault prolapse was 7.1%, while that in patients with severe uterovaginal prolapse was 22.4%. Of the 25 patients with hydronephrosis, 16 (64.0%) had complete resolution of hydronephrosis after treatment, 5 (20.0%) had residual but smaller degrees of hydronephrosis, and 4 (16.0%) were lost to follow-up. The incidence of renal impairment was 3.3%.

CONCLUSIONThe local incidence of hydronephrosis in patients with severe uterovaginal or vault prolapse was 20.6% in our study. We established that 3.3% of women with severe uterovaginal or vault prolapse had mild renal impairment. Treatment by vaginal surgery for severe uterovaginal or vault prolapse appears to result in either complete resolution or improvement of hydronephrosis in the majority of patients.

INTRODUCTIONThis retrospective study assessed the surgical outcomes of patients for whom the transobturator polypropylene mesh kit was used for the management of pelvic organ prolapse (Gynecare Prolift) in a tertiary urogynaecological centre in Singapore from January 1, 2006 to December 31, 2007.

METHODS169 patients (2006 n = 95; 2007 n = 74) with total (n = 76), anterior (n = 82) and posterior (n = 11) Prolifts were followed up for two years post-surgery.

RESULTSIntraoperatively, the incidence of haematoma, blood loss > 1,000 mL and blood transfusion was lower in 2007 than in 2006, although the difference was not statistically significant. One (1.4%) patient had rectal perforation in 2007. The mesh erosion rates were similar for all Prolift types (total 17.2%; posterior 14.5%; anterior 18.2%). Two patients, who had total Prolift in 2006, required mesh excision under anaesthesia for mesh extrusion. 138 (81.7%) patients were available for review at two years - nine (6.5%) patients had recurrent cystourethrocoeles and two (1.4%) had recurrent vault prolapse. Of the nine patients who had total Prolift with uterine conservation, two (1.4%) had recurrent uterine descent. The subjective cure rates two years after Prolift surgery were 98.7% for patients from 2006 and 100% for patients from 2007. The objective cure rates were 89.6% for patients from 2006 and 91.8% for patients from 2007.

CONCLUSIONProlift mesh surgery appears to have a very high success rate for pelvic reconstructive surgery. The learning curve of the surgeon may, however, be a factor determining surgical outcome in these patients.
