Clean intermittent catheterization rates after initial and subsequent treatments with onabotulinumtoxinA for non-neurogenic overactive bladder in real-world clinical settings.

OBJECTIVE: Previous randomized controlled trials have reported a 6.1-6.9% incidence of clean intermittent catheterization (CIC) following treatment with onabotulinumtoxinA in non-neurogenic overactive bladder (OAB) patients who were inadequately managed by ≥1 anticholinergic. A multi-center retrospective chart review assessed the real-world rate of voiding dysfunction requiring catheterization. METHODS: Patients received onabotulinumtoxinA 100 U (approved dose) administered by experienced injectors between January 2013 and June 2015. Patients using CIC or an indwelling catheter for ≥24 hours for voiding dysfunction prior to onabotulinumtoxinA injections were excluded. The primary outcome was post-treatment CIC (lasting >24 hours; per individual physician's clinical judgment considering patient's voiding symptoms, post-void residual [PVR] urine volumes and patient bother). Potential baseline predictors of CIC (history of pelvic prolapse, cystocele, diabetes, PVR urine volume and age) were assessed using multivariable logistic regression. RESULTS: Overall, 299 patients received their first treatment with onabotulinumtoxinA 100 U. Mean age was 66.4 years; 98.3% were female. The incidence of CIC was 2.7% in the total study population after the first treatment with onabotulinumtoxinA. The de novo CIC rate in treatments 2 and 3 combined was similarly low (3.2%). None of the evaluated baseline characteristics were significant predictors of CIC initiation due to the low CIC incidence. CONCLUSIONS: This real-world study of non-neurogenic OAB patients treated with onabotulinumtoxinA suggests that the CIC rate is lower than the rates reported in previous studies. There were no significant correlations between baseline predictors and CIC initiation, although statistical significance may not have been reached because of the low incidence of CIC.

Minimally invasive therapies for female stress urinary incontinence: the current status of bioinjectables/new devices (adjustable continence therapy, urethral submucosal collagen denaturation by radiofrequency).

The aim of this review is to provide an update on the current status of evolving minimally invasive therapies for stress urinary incontinence. Bioinjectables have been available for some time and their current status is reviewed. The adjustable continence device has been used as a salvage procedure for females for a number of years in clinical trials, yet many are unfamiliar with it. Lastly, radiofrequency via a transurethral route has also been utilized in small numbers and will be updated. These later two emerging technologies need further exposure to better define their role in our clinical practice.

Adjustable continence therapy for treatment of recurrent female urinary incontinence.

PURPOSE: The Adjustable Continence Therapy (ACT) device has been developed for the treatment of recurrent stress urinary incontinence resulting from intrinsic sphincter deficiency (ISD) by increasing urethral coaptation. We critically evaluated the technique and its results. METHODS: The ACT device consists of two balloons each attached to an injectable port placed in the labia majora. The port enables postoperative adjustment in balloon coaptation pressure. All 49 patients had previously failed anti-incontinence surgery. Each patient was implanted with the ACT device and assessed by preoperative and postoperative overall impression, incontinence quality of life questionnaire, and visual analog scale; 38 of the 49 subjects had a minimum of 1 year of data collected, including pad use, number of adjustments needed, and complications. RESULTS: Mean operative time was 20.3 minutes (range 10-30 minutes), with 88% of implantations performed using local or regional anesthesia. Balloon adjustments were needed in 62%; 68% of patients reported being dry and 16% improved. Complications included migration (12%), balloon failure (3.6%), and erosion (4%). CONCLUSION: The ACT device provided significant improvement in at last 70% of patients with recurrent stress urinary incontinence.
