By elucidating the risk factors that influence the success rate of mixed UI, which generally demonstrates a lower success rate compared to pure stress urinary incontinence, the objective of our study was to identify predictive clinical factors associated with the postoperative cure rate and satisfaction in female patients with equal severity of SUI and UUI.

90 patients diagnosed with an equal severity of SUI and UUI underwent trans-obturator tape (TOT) in single center. Cases with stress-predominant or urge-predominant mixed UI were excluded. Also, the study excluded patients with intrinsic sphincter deficiency (ISD) and other complications (neurogenic bladder, comorbidities such as multiple sclerosis or diabetes, concurrent surgeries, or uterovaginal prolapse). The postoperative cure rate was categorized into three groups: (1) cure, (2) improve, and (3) fail [4]. The postoperative cure status was divided into the cure group (CG) and the fail group (FG). Postoperative satisfaction was classified into four groups: very satisfied, satisfied, no change, and dissatisfied. Furthermore, postoperative satisfaction was divided into the satisfied group (SG) and the dissatisfied group (DG).

There were 66 patients (73.3%) in the SG and 24 patients (26.7%) in the DG. For the postoperative cure rate, 84 patients (93.3%) were classified in the CG, while 6 patients (6.7%) were in the FG. There were significant differences between the satisfaction groups (SG and DG) in VLPP (P = 0.041), BMI (P = 0.028), and OABSS (P < 0.001). significant differences were observed between the cure groups (CG and FG) in VLPP (P = 0.011) and OABSS (P < 0.001). Univariate analysis revealed that BMI, total capacity, and OABSS were associated with postoperative satisfaction, while VLPP and OABSS were related to the postoperative cure rate. In the multivariate analysis, OABSS (adjusted odds ratio = 0.15, P = 0.001) and BMI (adjusted odds ratio = 0.86, P = 0.032) were identified as independent predictors of postoperative satisfaction, while VLPP (adjusted odds ratio = 1.047, P = 0.023) was the only independent factor for the postoperative cure rate.

Higher VLPP was associated with higher postoperative cure rates, while lower BMI and OABSS scores were associated with higher postoperative satisfaction.
