PURPOSE: The Lima constrictor was described in 1996 as a less complex and less expensive alternative to the artificial urinary sphincter for use in cases of pediatric neuropathic sphincter incontinence. The device provides a fixed periurethral resistance which creates continence, yet allows urethral catheterization without the need to deflate the cuff. We report our multicenter experience, and continence, revision and erosion rates. MATERIALS AND METHODS: We performed a retrospective review of 14 consecutive patients who underwent insertion of the periurethral constrictor (Silimed, Rio de Janeiro, Brazil) between 2005 and 2011. Data are presented as medians (range). RESULTS: A total of 14 patients (13 male, 1 female) with spina bifida (10), sacral agenesis (3) and Hirschsprung disease (1) underwent insertion of the constrictor at a median age of 12 years (range 8 to 20). All patients were wet despite clean intermittent catheterization, medical therapy and/or previous surgery. Eleven patients underwent simultaneous bladder augmentation and/or Mitrofanoff formation. The constrictor was activated a median of 8 weeks (range 2 to 99) after the procedure in 11 patients whereas 3 became dry without activation. Complications occurred in 4 patients (29%), including spontaneous bladder perforation and constrictor erosion (1), tubing disconnection requiring revision (2) and wound infection (1). At a median of 23 months of followup (range 7 to 77) 13 patients were dry and 1 was damp. All patients performed urethral or Mitrofanoff clean intermittent catheterization. The continence rate with the device in situ was 92%. CONCLUSIONS: At a median followup of 23 months the Lima constrictor provided a 92% continence rate with erosion and revision rates of 7% and 14%, respectively. Interim results suggest that the constrictor provides a safe and effective surgical option, particularly in patients who are unable to void to completion.
