OBJECTIVE: To evaluate the safety and efficacy of modified Prolift pelvic floor reconstruction with improving the placement of Prolift-A in treatment of severe pelvic floor dysfunction and stress urinary incontinence (SUI).

METHODS: From July 2008 to September 2010, 170 cases with severe pelvic organ prolapse (POP) treated by modified Prolift pelvic floor reconstruction surgery in Fuzhou General Hospital were enrolled in this study. The Prolift-A was laid tension-free under the mid-urethra with the position of Prolift-A displaced from the neck of bladder to the mid-urethra. No concomitant tension-free urethra suspender via vagina was performed. Primary outcomes were assessed with POP quantitation (POP-Q) system to evaluate the postoperative anatomical replacement stage. Secondary outcome measure were: urogenital distress inventory 6 (UDI-6), the incontinence impact questionnaire 7 (IIQ-7) and the pelvic floor incontinence questionnaire 7 (PFIQ-7) to evaluate the impact on life quality at the follow-up of 1, 6, 12 months.

RESULTS: At 6 and 12 months after surgery, 168 cases and 163 cases were followed up. The anatomical cure rates were 98.8% (166/168) at 6 months and 97.5% (159/163) at 12 months, respectively. One case with bladder injury and 1 case with rectum injury were observed. Five cases with recurrence were observed, including 2 cases with anterior vagina prolapse, 2 cases with uterine prolapse and 1 case with posterior vagina prolapse. Meanwhile, 3 cases with hematoma and 7 cases with mesh erosion were observed. Quality of life of all patients were improved significantly by UDI-6, IIQ-7 and PFIQ-7 scoring system evaluation. Among 79 POP patients with SUI, the cure rate of SUI was 93.7% (74/79). Of 5 cases with symptomatic SUI, 2 cases were needed surgical intervention. Twenty-three cases were found with minimal SUI symptoms and subjective satisfaction without objective influence on quality of life. Seven patients presented dysuria after surgery, 5 cases recovered urination with 10 days, 1 case recovered with 1 months, and 1 case with 6 months by bladder drainage. Eleven cases with discomfort urination and 3 cases with slow urination were found.

CONCLUSIONS: The modified Prolift pelvic reconstructive surgery was safe and efficacy intervention in treatment of POP and prevention of SUI.
