Abstract
We report two hemodialysis patients who required treatment for hydronephrosis after total cystectomy. Case 1 complained of left lumbago due to huge hydronephrosis 10 months postoperatively. Percutaneous needle drainage under ultrasonography was performed. The drained urine was bloody but negative for cytology. Case 2 had residual tumor in the left upper urinary tract. One month postoperatively, he complained of severe left lumbago probably due to hemorrhage from the residual tumor, which required nephrectomy. These two cases imply the importance, of the indication of total cyctectomy with bilateral nephro-ureterectomy and of periodical check up for upper urinary tract after cystectomy, in hemodialysis patients.
