Nephrostomy or ureterostomy has been widely accepted as a fairly effective method of urine diversion. Many uremic patients with carcinomas originating from intrapelvic organs such as the urogenital tract or the colon showed a favorable response to this procedure, although some died postoperatively.
Correlation between the preoperative clinical examinations and their postoperative courses in our 96 cases was analysed in detail. Nephrostomy or ureterostomy brought a succesful result even in patients under poor conditions. However, the procedure should not be recommended in cases with BUN elevated over 150mg/dl, serum potassium over 8.0mEq/l, RBC over 5×10⁶ or under 2×10⁶ and WBC over 3×10⁴ or under 2×10³. For such cases, other procedures such as artificial dialysis must be tried first of all.
