Objectives: The short‐term results for the tension‐free vaginal tape procedure (TVT) and the transobturator tape procedure (TOT) for stress urinary incontinence (SUI) were compared using the preoperative maximum urethral closure pressure (MUCP). Methods: A total of 278 patients treated for SUI was considered: 165 who underwent TVT and 113 who underwent TOT retrospectively. The MUCP in a preoperative urodynamic study before and 3 months after surgery were evaluated. Results: At 3 months after TVT, 159 patients (96.4%) were cured and four patients failed. The mean MUCP of the patients who failed was 22.5 ± 5.3 cmH 2 O, which was significantly lower than that among the cured patients (P < 0.007). At 3 months after TOT, 100 patients (88.5%) were cured and seven patients failed. The mean MUCP of the patients who failed was 27 ± 6.3 cmH 2 O, which was significantly lower than that among the cured patients (P < 0.001). Furthermore, the mean MUCP among the patients who were cured after TOT was significantly higher than that among the patients who were cured after TVT (P < 0.01). A further analysis using a ROC curve indicated that the MUCP value in the successful patients after TVT was ≧ 24 cmH 2 O and that in the failures after TOT was ≦ 30 cmH 2 O with selection sensitivity at 80%. Conclusion: These results suggest that the failure cases after TVT or TOT are often found in SUI with a low MUCP and that TVT might be superior to TOT in SUI with a MUCP ≦ 30 cmH 2 O.
