title: Effectiveness of a urinary control insert in the management of stress urinary incontinence: early results of a multicenter study.
abstract: OBJECTIVE
  The purpose of this study was to test the safety and effectiveness of a urethral insert for managing stress or mixed urinary incontinence.
  
  
  METHODS
  We performed a prospective, multicenter study of 135 female patients who were treated for 4 months with the Reliance Urinary Control Insert. The effectiveness of the insert was measured objectively at the time of first use and after 4 months' use by standardized pad weight studies. Insert effectiveness was also measured by reports of symptom improvement during patient interviews and on patient diaries. Urine microscopy and culture were obtained monthly; cystoscopy and urodynamics were conducted at study entry and at 4 months.
  
  
  RESULTS
  Significant improvement in involuntary urine loss was observed. Objective measurement of urine loss revealed that 80% of the patients were completely dry, and 95% of the patients achieved greater than an 80% decrease in urine loss. In addition, patients' perceptions of acceptability, incontinence symptom improvement, ease of learning, comfort, and time to habituation also showed improvements. Untoward events reported during the study included hematuria, bacteriuria, and bladder irritation. These events did not require significant medical intervention and did not result in any long-term clinical sequelae.
  
  
  CONCLUSIONS
  These preliminary results indicate that the Reliance Urinary Control Insert may be a safe, effective, and well-tolerated alternative to other available methods for the management of stress or mixed incontinence in women. Additional long-term follow-up will be required to substantiate this conclusion.
