Efficacy and security of continent catheterizable channels at short and middle term for adult neurogenic bladder...

The objective of this study was to assess the effectiveness and the complications rate following continent cutaneous channels (CCC) procedures, at short and medium term follow-up (FU).

A continuous retrospective case series (2008-2018): all patients who have undergone a CCC for neurogenic bladder were included in our department. The primary outcome was the effectiveness of CCC defined by the status of catheterizability (by the patient or a care-giver), continence of the tube, and absence of reintervention at 3 and 12 months FU. The secondary outcome was the prevalence of postoperative complications at 3 and 12 months FU.

Fifty-three patients were included during the study period in our department. Median follow up was 3,3 years (1.5-6.1). The overall effectiveness of CCC was 67.9% (n=36/53) at 3 months FU and 45,3% (n=24) at 12 months FU. The global rate of complications was 60.4% (n=32/53) at 3 months, and 73.6% (n=39/73) at 12 months FU. The statistical analysis showed no statistical differences on efficacy and complications in the different subgroups of CCC.

In the current series, the effectiveness and the complications rates following CCC were comparable across the procedure types.
