Abstract OBJECTIVE: To evaluate treatment-related morbidity following cystectomy in a cohort of consecutive bladder cancer patients. The impact of age, comorbid condition, previous pelvic radiotherapy and type of urinary diversion was analysed. MATERIAL AND METHODS: Between 1992 and 1998 the treatment-related early (<30 days after cystectomy) and late morbidity was recorded in 268 consecutive bladder cancer patients (median age 65 years) undergoing cystectomy and the following types of urinary diversion: ileal conduit, n = 195; orthotopic neobladder, n = 36; continent reservoir, n = 33; and ureterocutaneous diversion, n = 4. Twenty-four patients had received previous pelvic radiotherapy and 79 had pre-existing morbidity. The median follow-up period was 5.4 years. RESULTS: The postoperative mortality rate was 2\%. Age >70 years and pre-existing morbidity (especially cardiovascular disease) significantly increased the mortality rate. No relationship was found between early complication (57\%) and re-exploration rates (17\%) and either age, previous radiotherapy, pre-existing morbidity or type of urinary diversion. Patients undergoing orthotopic neobladder or continent reservoir had a significantly increased risk of calculus formation as well as cystectomy-related surgical procedures compared to patients undergoing ileal conduit. Age had a significant impact on vitamin B12 deficiency and renal deterioration, whereas previous pelvic irradiation significantly increased the probability of ureteroenteric stricture and lost renal function. Age and urinary diversion had no impact on hernia, ureteroenteric stricture or pyelonephritis. CONCLUSION: The risk of treatment-related morbidity was high and careful patient selection before cystectomy seems important. The lack of standard criteria regarding how to report morbidity makes comparison with other studies difficult.
