feasibility study of a voro urologic scaffold (arid)

Conditions: Stress Urinary Incontinence; Radical Prostatectomy

Summary: the objective of this study is to evaluate the safety and performance of the voro urologic scaffold as a prophylactic treatment for post-prostatectomy stress urinary incontinence. the study is a prospective, multicenter, single arm study. up to 40 subjects will be treated at up to 3 investigational sites in panama. subjects will be followed up post-treatment at catheter removal, 6 weeks post prostatectomy, 3 months, 6 months, 12 months and 2 years.

approximately 300,000 men undergo radical prostatectomy (rp) worldwide for the treatment of prostate cancer. rp has favorable oncology outcomes but carries risks of erectile dysfunction and urinary incontinence. urinary incontinence after rp has negatively affects patient quality of life. the bioresorbable voro urologic scaffold is designed to be placed over the anastomotic site during an rp procedure, between the bladder neck and urethral stump, to constrain the urethra immediately proximal to the urinary sphincter. the device is designed to relieve the load on the urinary sphincter. as the anastomosis heals, connective tissues form in the scaffold geometry while the scaffold material resorbs and hence potentially reduce the risk of acute and chronic stress incontinence. the objective of this study is to evaluate the safety and performance of the voro urologic scaffold as a prophylactic treatment for post-prostatectomy stress urinary incontinence. the study is a prospective, multicenter, single arm study. up to 40 subjects will be treated at up to 3 investigational sites in panama. subjects will be followed up post-treatment at catheter removal, 6 weeks post prostatectomy, 3 months, 6 months, 12 months and 2 years.
