Purpose: Bladder outlet obstruction (BOO) commonly causes detrusor overactivity (DO). In this study, a post hoc analysis of previous obtained data, we investigate if DO occurring in initial phases of BOO is associated with changes in urinary adenosine triphosphate (ATP) levels. Methods: Adult female Wistar rats were submitted to partial BOO (pBOO) or to sham obstruction. Cystometry was performed at 3 or 15 days after pBOO and saline voided was collected for ATP determination. Normality was tested using Shapiro-Wilk test. The mean frequency of voiding contractions (VCs) of the sham-operated animals at 15 days after surgery, plus or minus 3 standard deviations, was used to represent the normal range. Statistical analyses were performed using the chisquare and Mann-Whitney tests. Results: DO was indicated by a VC frequency greater than or equal to 0.9 VCs/min. DO was observed in 63% of animals at 3 days and in 33% at 15 days following pBOO. ATP levels were significantly higher in rats with DO compared to those without DO. Conclusions: The DO phenotype, occurring in the initial phases of BOO, is associated with comparatively high urinary ATP levels.

Purpose: To evaluate the safety and efficacy of a surgical polypropylene mesh for correction of anterior vaginal prolapse, with or without apical defects, by providing simultaneous reinforcement at the anterior and apical aspects of the vagina with a single- incision approach. Methods: This was a prospective, multicenter, single-arm study involving women with baseline stage ≥2 anterior and/or apical vaginal wall prolapse according to the Pelvic Organ Prolapse Quantification (POP-Q) system. The primary endpoint was defined as achievement of POP-Q stage ≤1 status. Additionally, patient-reported outcomes were assessed using the International Consultation on Incontinence Questionnaire-Vaginal Symptoms (ICIQ-VS). The device under evaluation was Calistar A, which is fixed posteriorly to the sacrospinous ligaments with a novel tissue-anchoring system (TAS) and anteriorly to the obturator internus muscles. Postoperative follow-ups were scheduled at 7 days and at 6, 12, and 24 months. Results: Ninety-seven women were treated and assessed for the primary outcome. They were followed for up to 2 years (n=43), with a median of 12 months. Objective cure was achieved in 86 of the 97 patients (88.7%) (P<0.0005). The mean reduction in the ICIQ-VS scores was in the range of 70%–90% for every time point (P<0.05). No bleeding or surgical revision was reported. Mesh exposure occurred in 7 patients (7.2%), urinary retention in 5 (5.2%), de novo dyspareunia in 3 (3.1%), and urinary tract infections in 7 (7.2%). Conclusions: This midterm follow-up showed that apical and anterior vaginal reinforcement with a polypropylene implant fixed with a TAS provided good anatomical correction, with no major complications.
