Objective: To find out the incidence of acute appendicitis leading to acute abdominal pain and necessitating appendectomy in the follow-up of patients after radical cystectomy and urinary diversions. Methods: A prospective 160 consecutive radical cystectomy patients with urinary diversion in whom appendectomy was not done between January 1991 and June 2001 were reviewed for the incidence of acute appendicitis. Ages ranged between 26 and 73 years. There were 143 males and 17 females. 120 patients had ileal conduit, 20 sigmoid neobladder, 5 continent urinary diversion, and 15 ureterosigmoidostomy as urinary diversion. Each patients was followed up regularly till death or last follow-up. The follow-up ranged between 4 months and 10 years (mean 6 years). Results: Intestinal obstruction (11%) and acute pyelonephritis (16%) were the most common causes of acute abdominal pain. The remaining causes include sigmoid neobladder perforation (0.6%), parastomal hernia (0.6%), urinary retention due to mucus (1.8%) and renal colic (1.8%). In all patients, diagnosis was easily made and they were managed accordingly. None of the patients had acute appendicitis requiring appendectomy on follow-up. Conclusion: Incidental appendectomy is not required during radical cystectomy as the risk of subsequent appendicitis is extremely low.
