Therapeutic Efficacy of Urethral Sphincter Injections of Platelet-Rich Plasma for the Treatment of Stress Urinary Incontinence due to Intrinsic Sphincter Deficiency: A Proof-of-Concept Clinical Trial.

ABSTRACT:

Purpose

The aim of this study was to investigate the efficacy of autologous platelet-rich plasma (PRP) in the treatment of stress urinary incontinence (SUI) due to intrinsic sphincter deficiency (ISD) refractory to medical treatment.

Methods

Thirty-five patients with SUI due to urodynamically proven ISD were prospectively enrolled. Five milliliters of PRP (2.5-5 times the platelet concentration in peripheral blood) was injected into the external sphincter at 5 sites; all patients received 4 injections at monthly intervals. The primary end-point was the change in SUI severity as assessed by a visual analogue scale (VAS of SUI). The secondary-endpoints were the Global Response Assessment score and changes in urodynamic parameters from baseline to 3 months after treatment.
