Conservative surgery for transitional cell carcinoma of the renal pelvis

From 1972 to 1986, 14 patients underwent a conservative operation for transitional cell carcinoma of the renal pelvis. Most of these patients had low grade (12), noninvasive (10) tumors involving a solitary functioning kidney (12). The operations performed were open pyelotomy with tumor excision and fulguration (8 patients), partial nephrectomy (5) and percutaneous nephroscopic fulguration (1). There was 1 operative death. Of the 13 surviving patients 8 (62 per cent) remained free of transitional cell carcinoma postoperatively, while 5 (38 per cent) had recurrent disease. Six patients (46 per cent) presently are free of tumor 6 months to 5 years postoperatively. Conservative surgical techniques can provide satisfactory treatment for selected patients with renal pelvic transitional cell carcinoma when preservation of functioning renal parenchyma is necessary to avoid kidney failure.
