The use of urea for dissolution of urinary mucus in urinary tract reconstruction

Abstract

Increased urinary mucus is common after urinary tract reconstruction involving the use of bowel segments. This mucus can prove troublesome when it interferes with emptying of the bladder reservoir, particularly in the prepubertal boy, in whom a small catheter must be be used. We report a rapidly effective, nontoxic, inexpensive method of dissolving urinary mucus by periodic instillation of a concentrated urea solution.
