Abstract
Purpose
To evaluate long-term (over 4 years) functional outcomes and quality of life of transobturator (TOR) and retropubic (RPR) routes in the cure of stress urinary incontinence (SUI).
Methods
Prospective, randomized multicentre study involving 88 women with SUI from March 2004 to May 2005 (RPR group (n = 42), TOR group (n = 46)). Long-term functional results and quality of life were evaluated using validated questionnaires and compared with those observed at the first year.
Results
Eight patients (19%) in the RPR group and 9 patients (19.5%) in the TOR group were lost to follow-up (NS). The mean follow-up in the RPR and the TOR groups was 52.7 months and 53.1 months, respectively. In intention to treat, the success rate at 4 years was 64.3% in the RPR group and 69.5% in the TOR group (NS). At 4 years, no significant differences in the IIQ scores were observed in either group compared to the preoperative scores with no difference between the groups (RPR group: 32 vs. 14.9 (NS), TOR group: 25.7 vs. 21.4 (NS)). Compared to 1 year UDIQ and IIQ scores, a decrease in quality of life was observed for both groups at 4 years (RPR group: 4.7 vs. 34 (P < 0.0001) and 2.6 vs. 14.9 (P < 0.001), TOR group: 1.2 vs. 38.7 (P < 0.0001) and 0 vs. 21.4 (P < 0.0001)) without difference between the groups.
Conclusions
This study shows similar relatively high long-term success rates for both the RPR and TOR procedures. Patients should be informed about a possible time-dependent alteration in functional results.
