PURPOSE: We compared functional outcomes in patients who received an artificial urinary sphincter in the space of Retzius vs the same device placed at a high submuscular location.

MATERIALS AND METHODS: We reviewed a prospectively maintained database of patients who received an artificial urinary sphincter between July 2007 and December 2014. After cuff placement was completed via a perineal incision, a 61 to 70 cm H2O pressure regulating balloon was placed through a separate high scrotal incision in the space of Retzius or in a high submuscular tunnel. Demographics, perioperative comorbidities and functional outcomes were compared between the groups.

RESULTS: A total of 294 consecutive patients underwent artificial urinary sphincter placement. Mean followup was 23 months. Space of Retzius and high submuscular placement was performed in 140 (48%) and 154 patients (52%), respectively. Functional outcomes were similar between the groups, including the continence rate (defined as 0 or 1 pad daily) in 81% vs 88% (p = 0.11), the erosion rate in 9% vs 8% (p = 0.66) and the explantation rate in 10% vs 11% (p = 0.62). Artificial urinary sphincter revision for persistent incontinence was required in a similar proportion of the 2 groups (13% vs 8%, p = 0.16) with a comparable mean followup (24 vs 23 months, p = 0.30). Kaplan-Meier analysis revealed no difference between the groups in the rate of explantation (p = 0.70) or revision (p = 0.06).

CONCLUSIONS: High submuscular placement of a pressure regulating balloon at artificial urinary sphincter surgery is a safe, effective alternative with functional outcomes equivalent to those of traditional placement in the space of Retzius.
