PURPOSE: Transitional cell carcinoma is the most common urinary tract cancer in Taiwanese patients on dialysis. It is a unique finding compared within Western countries. Due to this geographic difference and a higher recurrence rate a more extensive operation and aggressive followup protocols should be refined for these patients on dialysis. MATERIALS AND METHODS: We retrospectively reviewed the medical records of all patients with transitional cell carcinoma who had end stage renal disease and underwent hemodialysis. Records were reviewed for hemodialysis duration, initial tumor location, tumor grade, stage, operative method, operative complication and final surgical status. Tumor grade and stage was determined by the WHO and proposed Jewett systems. Six patient groups were classified according to final surgical status for comparative analysis. RESULTS: A total of 30 patients were included in this study. Painless gross hematuria and urethral bloody discharge were the most common complaints. Tumor in 25 of the 30 cases was high grade and all were early stage. Of the patients 11 (36.7%) had undergone bilateral nephroureterectomy and radical cystectomy in as a 1 or multiple step procedure. Six patients (20%) had undergone bilateral nephroureterectomy at 1 or 2 sequential operations. Seven of the 13 patients (53.8%) in whom low urinary tract transitional cell carcinoma was initially treated with transurethral resection unfortunately had recurrent transitional cell carcinoma of the upper urinary tract. Ten of the 14 patients (71.4%) with upper urinary tract transitional cell carcinoma who underwent nephroureterectomy and bladder cuff excision had subsequent transitional cell carcinoma within the bladder. CONCLUSIONS: Patients with transitional cell carcinoma on dialysis had a higher recurrence rate in the upper urinary tract than patients not on dialysis. Most cases were at an early stage but with high grade tumor behavior. In 11 patients (36.7%) total exenteration of the urinary tract except the urethra was eventually done. The final bilateral nephroureterectomy rate was 56.7%. Since the rate of total exenteration and bilateral nephrectomy was abnormally high at such a short followup, 1-step bilateral nephroureterectomy and radical cystectomy are a recommended treatment for patients with transitional cell carcinoma on dialysis.
