A comparative study on two surgical procedures in treatment of stress urinary incontinence in old women / 中华老年医学杂志

ABSTRACT

Objective To evaluate the safety and efficacy of two surgical procedures including retropubic space pathway and obturator foramen pathway in treatment of the old women with stress urinary incontinence (SUI). Methods Intravaginal Slingplasty (IVS) procedure by retropubic space pathway was performed in 52 cases with simple SUI from June 2003 to June 2005. And the modified Transobturator Vaginal Tape Inside-Out (TVT-O) procedure was carried out in 112 cases with simple SUI from October 2005 to October 2008, using self-tailed polypropylene mesh and helical needles. The comparative retrospective study was performed between these two groups. Results The cure rate was 80.8% (42/52) and the improvement rate was 13.5% (7/52) in IVS group. And the corresponding data were 84.8% (95/112) and 11.6% (13/112) in modified TVT-O group. The 3 (5.8%) cases failed in IVS procedure and 4 (3.6%) cases failed in modified TVT-O procedure at 1 month's follow-up. All of the 7 patients received the 'Tong's hammock procedure' and no cases failed at 6 and 12 month's follow-up. One case of vaginal erosion was found in each group although good effect of continence was observed. Meshes were removed in these two patients and then the 'Tong's hommock procedure' was performed which turned out to be good outcome. Bladder injuries were found in 3 cases when route cystoscopy was performed. No significant difference in efficacy was found between these two groups(P＞0. 05). In modified TVT-O group, operative duration, blood loss and medical cost were significantly reduced as compared with IVS group (P＜0. 01). Conclusions Both of the two surgical procedures of modified TVT-O versus IVS are simple, safe and mini-invasive procedures with high efficacy. However, the modified TVT-O procedure is more easy to be adopted by patients due to short operative time and lower medical cost.
