Long-Term Survival Rate of ATOMS Implant for Male Stress Urinary Incontinence and Management of Late Complications

BACKGROUND: stress urinary incontinence (SUI) still represents a major drawback of prostate surgery. The aim of this study is to evaluate long term efficacy, safety and survival of ATOMS system implant in a single center. METHODS: we retrospectively included al consecutive patients treated with ATOMS implant for SUI from October 2014 to July 2019. Patients received anamnesis, urodynamic evaluation, pre- and postoperative 24 h pad test and count. Patients were considered "continent" when dry or when wearing a security pad (social continence). RESULTS: we treated99 patientswith median age 77.98 years (IQR 72.7-82.52). Most of the patients had undergone radical prostatectomy. Median follow-up was 62.9 months (IQR 47.5-75.9). At last follow-up 74 (74.7%) patients reported continence. We had 21 early (<30 days) postoperative complications, all Clavien-Dindo (CD) grade 1 [11 temporary perineal pain, 4 urinary retention, 3 scrotal edema, 2 superficial wound dehiscence, 1 dysuria]. We had late postoperative complications in 28 patients [7 port dislocations requiring surgical repositioning (CD 3a), 6 device removals (CD 3a) due to port erosion (2), inefficacy (2), cushion leakage (1), mesh detachment (1), perineal pain (5), 2 cases of port extrusion solved with port removal leaving the device in place (CD 3a), 2 superficial wound dehiscence (CD 1), 2 UTI (CD 1), 1 scrotal edema (CD 1), 1 cushion deflate (CD 1), 1 dysuria (CD 1), 1 perineal pain (CD 1)]. The survival of the device was 97% at 12 months, 93% at 24 months, 91% at 36 months, 90% at 48 months and 87.9% at 60 months. CONCLUSIONS: This study demonstrates the good safety and efficacy of ATOMS implant for the treatment of SUI.
