MATERIALS AND METHODS: Records of 688 women between January 2004 and July 2017 were retrospectively reviewed. Patients received urodynamic studies, 1-hour pad test, Urogenital Distress Inventory-6 and Incontinence Impact Questionnaire-7, and were divided into normal weight, overweight and obese. Objective cure at 1 year was defined as no involuntary urine leakage during filling cystometry and pad test less than 2 gm. Subjective cure was established by negative response to question 3 on Urogenital Distress Inventory-6. McNemar's test, chi-square test, Mann-Whitney U and Fisher's exact test were used for paired categorical variables. Independent samples t-tests and paired t-test were used for continuous parametric variables. Multivariate logistic regression was used to identify risk factors for failure.

RESULTS: Objective and subjective cure in normal, overweight and obese patients was 91.4% and 89.1%, 87.5% and 86%, and 76% and 70.1%, respectively. There was no difference in surgical complications. Obese patients had worse quality of life scores preoperatively and postoperatively. Risk factors in obese patients with failed mid urethral sling included 66 years old or older (OR 2.02, 1.56-3.98), menopause (OR 4.21, 1.21-14.22), previous prolapse surgery (OR 4.57, 2.36-8.52), diabetes (OR 2.79, 1.61-5.99) and intrinsic sphincter deficiency (OR 5.06, 3.08-9.64).

MATERIALS AND METHODS: A prospective cohort study, 139 women, underwent transvaginal surgery for anterior and/or apical POP > stage 2, 69 patients had SIM A and 70 patients had SSF. The objective cure was defined as POP ≤ stage 1 anterior, apical according to POP-Q. Subjective cure is patient's negative feedback to question 2 and 3 of pelvic organ prolapse distress inventory 6 (POPDI-6). Patient's satisfaction was reported using validated quality of life questionnaires. Multi-channel urodynamic study was used to report any voiding problems related to the prolapse surgery 6 months after surgery.

RESULTS: 119 patients completed a minimum of 3 years follow-up. 89.8% is the overall prolapse correction success rate for SIM A and 73.3% for SSF group (p = 0.020), and 96.6% versus 73.4% at the anterior vaginal compartment respectively (p ≤ 0.001). Statistically significant difference was noticed in apical compartment with 98.3% with SIM A and 85.0% with SSF (p = 0.009). The subjective success rate, 86.4% in the SIM A and 70.0% in the SSF arm (p = 0.030) was significantly noted. Only, Pelvic Organ Prolapse Distress Inventory-6 (POPDI-6) showed significant improvement. Operation time and intra-operative blood loss tend to be more with SIM A.
