Urethral overdilation for women with voiding dysfunction

Abstract

  • © 2014. Objective: This was a retrospective study of the efficacy of urethral overdilation (UOD) for women with voiding dysfunction. Materials and methods: Thirty-six patients diagnosed with voiding dysfunction were enrolled. The main indications for UOD included women with poor compliance (30 patients, 83.3%) and obstructive symptoms with high residual urine (6 patients, 16.7%). We utilized a method called UOD (wide caliber), dilating the urethra up to 54 Fr. Patients were re-evaluated every 3 months with serial free flow rate and ultrasound residual in the first year and then as scheduled. Outcome measure was based on the change in videourodynamic parameters, Urogenital Distress Inventory-6 (UDI-6) questionnaire, and International Prostate Symptom Score (IPSS). Results: Mean follow up period of 33.2 months (range: 13-61 months). Failure or success depended on the change in videourodynamic parameters, UDI-6 score, and IPSS. The mean age with the Success Group (. n=22, 61.1%) and Failure Group (. n=14, 39.3%) was 52.8 years and 54.1 years, respectively. Our data showed significant improvements in mean UDI-6 score and IPSS after treatment (11.5-5.7, p=0.032 and 14.8-5.2, p=0.006, respectively). By analyzing multiple parameters (age, parity, body mass index, videourodynamics parameters, anesthesia bladder capacity, UDI-6 score, and IPSS) between the success and failure groups, we found only anesthesia bladder capacity reached statistical significance (536mL vs. 418mL, p=0.005). Conclusion: The present study provides evidence that UOD, as a minimally invasive procedure, achieves a satisfactory cure rate on short-term follow-up for women with voiding dysfunction.
