Purpose: We studied the effect of repeat detrusor botulinum neurotoxin type A injections on urinary symptoms, health and quality of life in patients with refractory neurogenic detrusor overactivity secondary to multiple sclerosis. Materials and Methods: This was a prospective, open label, single center study in 137 patients with multiple sclerosis treated with detrusor injections of botulinum neurotoxin type A with observations made from 2002 to 2009. A minimally invasive outpatient technique was used for injection. Patients were asked to contact the department if and when they required repeat treatment. Recurrent detrusor overactivity was then identified on urodynamics. The primary outcomes measured were the change in symptoms and quality of life, as assessed by the Urogenital Distress Inventory, Incontinence Impact Questionnaire and EuroQol-5 Dimensions questionnaires (www.ion.ucl.ac.uk/departments/repair/ themes/uroneurology) before and 4 weeks after botulinum treatment. Continence status, the need for clean intermittent self-catheterization before and after injections, and interinjection intervals were also analyzed. Results: Mean Urogenital Distress Inventory and Incontinence Impact Questionnaire 7 scores showed considerable improvement 4 weeks after each treatment even when repeated 6 times. Almost all patients relied on clean intermittent self-catheterization after treatment. Before the first treatment 83% of patients were incontinent but 4 weeks after the first treatment 76% (104 of 137) became completely dry. This efficacy was sustained with repeat injections. The median interval between re-treatments remained constant at 12 to 13 months. Conclusions: Repeated detrusor botulinum neurotoxin type A injections for refractory neurogenic detrusor overactivity in patients with multiple sclerosis have a consistent effect on bladder control, resulting in sustained improvement in quality of life. © 2011 American Urological Association Education and Research, Inc.

Objective: To compare GnRH agonists and antagonists in oocyte-donation IVF treatment cycles by a systematic review and meta-analysis of trials. Design: Systematic review and meta-analysis of randomized clinical trials (RCT). Systematic literature searches were conducted, and all randomized trials that compared GnRH agonists with antagonists in oocyte-donation IVF treatment cycles were included. Study selection, quality appraisal, and data extractions were performed independently and in duplicate. Setting: Tertiary fertility center. Patient(s): A total of 1,024 oocyte donors treated in eight RCTs. Intervention(s): Comparison of GnRH agonists versus antagonists in oocyte-donation IVF treatment. Main Outcome Measure(s): Ongoing pregnancy, oocytes retrieved, duration of stimulation, gonadotropin consumption, and ovarian hyperstimulation syndrome incidence (OHSS) per randomized oocyte donor. Result(s): Meta-analysis of these studies showed no significant difference in ongoing pregnancy rate between the GnRH agonists and antagonists (risk ratio [RR] 1.15, 95% confidence interval [CI] 0.97 to 1.36). The duration of stimulation was significantly lower with the GnRH antagonist protocol (weighed mean difference [WMD] -0.90 days, 95% CI -1.61 to -0.20). No significant differences were observed in the number of oocytes retrieved (WMD -0.60, 95% CI -2.26 to +1.07), gonadotropin consumption (WMD -264 IU, 95% CI -682 to +154), or OHSS incidence (RR 0.62, 95% CI 0.18 to 2.15). Conclusion(s): No significant differences were observed in ongoing pregnancy rate or the number of retrieved oocytes after donor stimulation with GnRH agonist or antagonist protocols. © 2011 American Society for Reproductive Medicine, Published by Elsevier Inc.

Purpose: To report 1-year results of a single-center randomized controlled trial comparing paclitaxel-coated balloon (PCB) versus high-pressure plain balloon angioplasty for the treatment of failing arteriovenous fistulae (AVFs). Materials and Methods: Forty patients (26 men; mean age, 61 y ± 14.63) were randomized at 1:1 to undergo PCB (n = 20) or high-pressure balloon (HPB; n = 20) angioplasty of dysfunctional AVFs. There were no significant differences in baseline demographics between groups. Enrollment required a clinical diagnosis of a dysfunctional AVF attributed to a single stenotic lesion verified with digital subtraction angiography. Primary endpoints included device success, anatomic success, clinical success, and target lesion revascularization (TLR)-free survival. Secondary endpoints included dialysis circuit primary patency and procedure-related complication rates. Results: Device success rates were 100% in the HPB group and 35% in the PCB group (P < 0001): further dilation with an HPB was needed to achieve anatomic success in 13 of 20 cases in the PCB group (65%). Anatomic and clinical success rates were 100% in both groups. TLR-free survival (PCB, 308 d; HPB, 161 d; hazard ratio [HR], 0.478; 95% confidence interval [CI], 0.236-0.966; P = .03) and access circuit primary patency (PCB, 270 d; HPB, 161 d; HR, 0.479; 95% CI, 0.237-0.968; P = .04) were significantly in favor of PCB angioplasty. No minor or major procedure-related complications occurred. Conclusions: In this single-center study, the use of PCBs resulted in superior TLR-free survival and dialysis access circuit primary patency of dysfunctional AVFs. However, additional HPB postdilation was required in the majority of cases.& SIR, 2015.
