A remote controlled intraurethral insert for artificial voiding: A new concept for treating women with voiding dysfunction

Abstract

Purpose: Many patients with voiding dysfunction find clean intermittent catheterization unsatisfactory. We evaluated the efficacy of the new remote controlled intraurethral In-Flow Catheter insert for treating women with voiding dysfunction. Materials and Methods: We evaluated the efficacy of the intraurethral insert in 92 women with a mean age of 56 years. The insert is available in various sizes to adapt to individual urethras. It comprises a valve and pump assembly. A remote control unit is operated to open the valve and activate the pump, generating active urine flow. Results: In 45 patients (49%) the device was removed after a mean of 7.1 days due to local discomfort or urinary leakage around the insert. At a mean followup of 7.6 months (range 2 to 26) 47 women (51%) continued to use the device, and all are dry with complete bladder emptying. The insert was replaced periodically at a mean of 38 days to prevent salt deposits in and around it which lead to urine leakage. Asymptomatic bacteriuria developed in 22 patients (46.8%). Clinical urinary tract infections resolved in 3.9% of all patients-months with oral antibiotics. No dyspareunia was reported. All patients were satisfied with the insert and preferred it to previous treatment modalities. Conclusions: This new remote controlled intraurethral insert is safe and effective in women with voiding difficulties.
