Increased urinary mucus production: a sequela of cystography following enterocystoplasty.

Early postoperative urinary mucus secretion was evaluated in 13 consecutive patients who underwent lower urinary tract reconstruction with incorporation of bowel segments, and the effect of intravesical infusion of sodium diatrizoate and meglumine diatrizoate in aqueous solution (Urografin 30%) was assessed. The mean volume of urinary mucus extracted before and immediately after cystography increased from 1.4 to 9.6 ml., respectively (p less than 0.0001). We conclude that mucus excretion increases significantly immediately following cystography during the early postoperative period. During that critical time cystography may cause potential hazards of mucus retention and catheter obstruction, which should be anticipated and treated promptly.
