Durability of Urethral Bulking Agent Injection for Female Stress Urinary Incontinence: 2-Year Multicenter Study Results

Two-thirds of patients were dry at 24 months. The durability of Macroplastique shows its effectiveness as a viable long-term therapy for female stress urinary incontinence primarily due to intrinsic sphincter deficiency.
