Biomechanical aspect of supravesical urine derivation by Bricker's method

The findings obtained by excretory urography in 15 patients of various age and occupation confirmed the study premise that in the upright position after the procedure of supravesical urine derivation as described by Bricker, the isolated segment of the ileum does not function as a conduit but forms a siphon-like receptaculum which, according to the laws of liquid mechanics, prevents or reduces the ascent of gases and bacteria into the upper urinary ducts. This also appears to be a logical explanation for a decreased incidence of infection of proximal urinary ducts in Bricker's method of supravesical urine derivation as compared to other mechanically comparable surgical procedures.
