[Functional dynamics of obstructive ileal conduits in children (author's transl)].

Bad late results following ileal conduit are usually caused by stomal obstruction. Poor emptying of the conduit, ureteric reflux and infection all combine to produce a pathological result. A manometric procedure to assess the functional performance of the conduit is presented. This allows for the diagnosis of early obstruction and decompensation. The most important measurements are a resting pressure of 1.2 kPa and the emptying pressure of 1.7 kPa and a compliance varying from 10 ml per kPa to 71 ml per kPa. The conduit must be isoperistaltic.
