Why are continent catheterizable channels continent? A stomal pressure profilometry feasibility study

A continent catheterizable channel (CCC) may be a solution for patients with impaired bladder emptying and difficult transurethral access. Leakage of the CCC is a common complication. To prevent leakage, the pressure in the CCC has to be higher than the reservoir (bladder/pouch) pressure in at least one location. It has not been clearly defined through which mechanism(s) the CCC achieves continence. In this feasibility study, we measured the CCC pressure profile in adult patients with various types of CCC's with and without stomal leakage.
