RESUMO
INTRODUCTION AND HYPOTHESIS: To study the surgical outcomes and risk factors for failure of three types of mid urethral slings(MUS) surgeries in elderly and old age women with urodynamic stress incontinence(USI). METHODS: Three different types of MUS surgeries [single incision sling(SIS), trans-obturator tape(TOT), retro-public mid-urethral sling-tension-free vagina tape (TVT)]were performed among three age groups of women (young <64 yr, elderly 65-74 yr and old >75 yr) with USI. They were followed up for 1 year. RESULTS: Complete postoperative data was available for 688 women. After 1 year, overall objective cure rate was 88.2% and subjective cure rate was 85.9%. Among the young, elderly, and old age women objective cure rates were 91.0%, 80.6%, 66.7% and subjective cure rates were 89.2%, 77.6%, 58.3% respectively. Urodynamic parameters demonstrated flow rate, higher post-void bladder residual, smaller cystometric capacity, and lower maximum urethral closure pressure were significantly lower among old and elderly group. Subjectively, urinary distress inventory-6 (UDI-6) and incontinence impact questionnaire-7(IIQ-7) improved significantly in all groups with significant changes from baseline only in older women. Intrinsic sphincter deficiency(ISD) was found to be significantly associated with failure in older women. Other preoperative comorbidities were equally distributed among all the three age groups. The operative time, perioperative complications, and length of hospital stay showed no difference between the study groups. CONCLUSIONS: MUS surgery is safe for the young and aging patients with USI and demostrated significant improvement in its outcomes, but objective and subjective cure rates decreases with age. ISD was also found to be significantly associated with failure.

STUDY OBJECTIVE: To evaluate the clinical outcome and identify risk factors for failure of the Solyx (Boston Scientific Corporation, Marlborough, MA) single-incision sling (SIS) in the treatment of urodynamic stress incontinence (USI). DESIGN: A retrospective observational study (Canadian Task Force classification II-2). SETTING: A tertiary referral center. PATIENTS: Patients diagnosed with USI without needing concurrent procedures that underwent continence surgery using the Solyx SIS from February 2015 to May 2017. INTERVENTIONS: Anti-incontinence surgery. MEASUREMENTS AND MAIN RESULTS: The primary outcome of this study was the rate of objective cure defined as the absence of demonstrable leakage of urine on the cough stress test and a 1-hour pad test weight of less than 2g. The secondary outcome was the rate of subjective cure defined as a negative response to Urinary Distress Inventory question 3 (no leakage on coughing, sneezing, or laughing) and the identification of the different risk factors of cure failure. A total of 113 patients were evaluated in the study. Postoperative USI and the 1-hour pad test significantly improved from 24.2 ± 26.9 gm (range, 19.1-29.3) to 2.5 ± 8.7 gm (range, 0.9-4.2); p <0.001 through 1 year. Data analysis showed an objective cure rate of 90% (102/113) and a subjective cure rate of 86% (97/113). USI recurred in 11 patients with no repeat surgery done becausesymptoms were tolerable to the patients. No patient had bladder outlet obstruction. Peak flow rates 23.7 ± 9.1 ml/s (20.0-27.4) and residual urine volume 38.5 ± 25.8 ml (29.8-47.2) were within normal limits with no significant changes. Previous anti-incontinent surgery, previous prolapsed surgery, intrinsic sphincter deficiency, maximum urethral closure pressure <40cm H2O, and neurogenic disease were significant risk factors for sling failure. Subjective assessment on the quality of life significantly improved (p <0.001). CONCLUSION: The Solyx SIS is an effective and safe treatment option for women with USI, showing high objective and subjective cure rates with a low incidence of complications 1 year after treatment. The identified independent risk factors forfailure are related to poor urethral function and previous pelvic reconstructive surgery.

INTRODUCTION AND HYPOTHESIS: The objective of this study was to identify the predictors of postoperative voiding dysfunction in women following extensive vaginal pelvic reconstructive surgery. METHODS: We enrolled 1,425 women who had pelvic organ prolapse of POP-Q stage III or IV and had undergone vaginal pelvic reconstructive surgery with or without transvaginal mesh insertion from January 2006 to December 2014. All subjects were required to complete a 72-h voiding diary, and the IIQ-7, UDI-6, POPDI-6 and PISQ-12 questionnaires. Urodynamic study was performed preoperatively and postoperatively. RESULTS: Of the 1,425 women, 54 were excluded due to incomplete data, and 1,017 of the remaining 1,371 (74.2 %) had transvaginal mesh surgery and 247 (18 %) had concurrent midurethral sling insertion. Of 380 women (27.7 %) with preoperative voiding dysfunction, 37 (9.7 %) continued to have voiding dysfunction postoperatively. Of the remaining 991 women (72.3 %) with normal preoperative voiding function, 11 (1.1 %) developed de novo voiding dysfunction postoperatively. The overall incidence of postoperative voiding dysfunction was 3.5 % (48/1,371). Those with concurrent midurethral sling insertion were at higher risk of developing voiding dysfunction postoperatively (OR 3.12, 95 % CI 1.79 - 5.46, p < 0.001). Diabetes mellitus, preoperative detrusor pressure at maximal flow (Dmax) <10 cm H2O and postvoid residual volume ≥200 ml were significant risk factors for the development of postoperative voiding dysfunction (OR 3.07, 1.84 and 2.15, respectively; 95 % CI 1.69 - 5.60, 1.39 - 2.91 and 1.10 - 3.21, respectively). CONCLUSIONS: Diabetes mellitus, concurrent midurethral sling insertion, preoperative Dmax <10 cm H2O and postvoid residual volume ≥200 ml in patients with advanced pelvic organ prolapse were risk factors for the development of postoperative voiding dysfunction after vaginal pelvic reconstructive surgery. Therefore, counseling is worthwhile before considering vaginal pelvic reconstructive surgery.
