Abstract

Purpose: We studied the feasibility, safety and efficacy of daily intravesical instillation of 1 mg of the endogenous peptide nociceptin/orphanin FQ in a selected group of patients who perform clean intermittent self-catheterization for neurogenic detrusor overactivity incontinence. Materials and Methods: A total of 18 patients with neurogenic detrusor overactivity incontinence and on clean intermittent self-catheterization were prospectively randomized to receive 1 mg nociceptin/orphanin FQ in 10 cc saline (9) or placebo (saline) solution (9) at the first morning catheterization for 10 days. All patients completed a voiding diary using a frequency/volume chart according to International Continence Society guidelines, and reported daily incontinence frequency. Mean changes in incontinence episode frequency and voiding diary mean bladder capacity from baseline throughout treatment were the primary outcome variables. Urodynamic parameters (cystomanometric bladder capacity, maximum bladder pressure) were also recorded at baseline and during the study. Results: The 2 groups were well balanced and all patients completed the study. The urodynamic parameters recorded during the study showed an increase in cystomanometric bladder capacity and a decrease in maximum bladder pressure compared to baseline only in patients assigned to the nociceptin/orphanin FQ group. Mean daily urine leakage episodes during nociceptin/orphanin FQ treatment were 0.94 vs a pretreatment baseline of 2.18 (p
