The Dissolution of Urinary Mucus after Cystoplasty

Abstract
Three agents have been tested for mucolytic activity to prevent or treat difficulties in bladder emptying following augmentation and substitution cystoplasty, particularly in patients emptying by intermittent self-catheterisation. Carbocysteine produced precipitation of mucus, which was found not to be helpful. N-acetylcysteine and urea both dissolved mucus, but urea proved to be more effective.
