BACKGROUND: Periprostatic artificial urinary sphincter implantation (pAUSi) is a rare yet relevant indication for male neurogenic stress urinary incontinence (SUI).
OBJECTIVE: To describe the surgical technique of robot-assisted pAUSi (RApAUSi) and compare the long-term functional results with the open pAUSi (OpAUSi).
DESIGN, SETTING, AND PARTICIPANTS: Data of 65 consecutive men with neurogenic SUI undergoing pAUSi between 2000 and 2022 in a tertiary centre were collected retrospectively.
SURGICAL PROCEDURE: Thirty-three patients underwent OpAUSi and 32 underwent RApAUSi. OpAUSi cases were performed by a single surgeon, experienced in functional urology and prosthetic surgery. RApAUSi cases were performed by the same surgeon together with a second surgeon, experienced in robotic surgery.
MEASUREMENTS: Outcome measures were achievement of complete urinary continence, intra- and postoperative complications, and surgical revision-free survival (SRFS).
RESULTS AND LIMITATIONS: RApAUSi showed superior results to OpAUSi in terms of median (interquartile range) operative time (RApAUSi: 170 [150-210] min vs OpAUSi: 245 [228-300] min; p < 0.001), estimated blood loss (RApAUSi: 20 [0-50] ml vs OpAUSi: 500 [350-700] ml; p < 0.001), and median length of hospital stay (LOS; RApAUSi: 5 [4-6] d vs OpAUSi: 11 [10-14] d; p < 0.001). Clavien-Dindo grade ≥3a complications occurred more frequently after OpAUSi (RApAUSi: 1/32 [3%] vs OpAUSi: 10/33 [30%]; p = 0.014). Achievement of complete urinary continence (zero pads) was comparable between the groups (RApAUSi: 24/32 [75%] vs OpAUSi: 24/33 [73%]; p = 0.500). The median follow-up periods were 118 (50-183) and 56 (25-84) mo for OpAUSi and RApAUSi, respectively (p < 0.001). A tendency towards longer SRFS was observed in the RApAUSi group (p = 0.076). The main study limitation was its retrospective nature.
CONCLUSIONS: RApAUSi is an efficient alternative to OpAUSi, resulting in shorter operative times, less blood loss, fewer severe complications, and a shorter LOS with similar functional results and need for revision surgery.
PATIENT SUMMARY: Compared with open periprostatic artificial urinary sphincter implantation (pAUSi), robot-assisted pAUSi leads to faster recovery and similar functional results, with fewer postoperative complications.
