Background: We report the multicentre comparison of the different port types of the adjustable transobturator male incontinence system (ATOMS, A.M.I., Austria). Methods: Between 10/09 and 10/16, 383 patients received an ATOMS.
Of these, 63% received the inguinal port (IP, 2009-2013), 23% the intraoperative manually connectable scrotal port (SP, 2013-2015), and 14% the pre-connected fully silicone-covered scrotal port (SSP, 2014-2016). During the follow-up period, continence parameters, pain and quality of life ratings and postoperative port-associated complications were evaluated and compared.
Statistical analysis was performed with GraphPad Prism 7(R), p < 0.05 considered as significant. Results: Regarding preoperative parameters (BMI, ASA score, previous radiotherapy/incontinence surgery, and preoperative 24-h pad count/24-h pad test), no significant differences were found.
Regarding perioperative parameters, the mean operative time was significantly shorter for the SP and SSP (IP vs. SP p < 0.0001, IP vs.
SSP p = 0.0048, SP vs. SSP p = 0.697).
Comparison of the postoperative 24-h pad count, 24-h pad test and uroflowmetry data revealed no significant differences. However, the postoperative ICIQ-SF score was significantly better for the SSP (p = 0.0232) than the SP.
A significant difference was also observed in postoperative port-associated complications. According to the Clavien-Dindo classification, we identified one grade I and 29 grade IIIb complications for the IP, 1 grade I and 6 grade IIIb complications for the SP, but only 2 grade IIIb complications for the SSP (IP vs.
SP p = 0.0231, IP vs. SSP p = 0.0189 and SP vs.
SSP p = 0.0453). Conclusion: The SSP shows fewer complications while retaining comparable efficacy.
