Use of the ileum as a substitute for the ureter should be taken into consideration when urinary tract continuity cannot be restored by using urinary tract tissue. Another important indication for this procedure is recurrent renal calculi, to permit the free passage of stones. It is essential to reserve this operation for those patients whose renal function is relatively adequate. Chronic renal insufficiency with a serum creatinine level above 2.0--2.2 mg% is a contraindication for the operation. Another prerequisite for the operation is that the patient is able to empty his bladder; otherwise deterioration of renal kidney function may occur. The present article gives a review on the ileal ureter, with emphasis on the indications and operative technique.

Four patients with upper urinary tract transitional cell carcinoma were treated with bacillus Calmette-Guerin (BCG) via a percutaneous nephrostomy tube or a retrograde ureteral catheter. A 68-year-old female and an 80-year-old male had carcinoma in situ (CIS) in the left upper urinary tract (cases 1 and 2). A man aged 47 had CIS in the left upper urinary tract, bladder, and prostatic urethra (case 3). CIS in the left upper urinary tract was identified in a woman aged 63 with chronic renal insufficiency (case 4). Two patients (cases 1 and 2) responded to this therapy. In the other two patients nephrectomy was performed due to residual tumor. There were extensive tuberculous granulomas in the kidneys. In one resected kidney (case 4) carcinoma had invaded the renal parenchyma. The reviewed literature showed that BCG perfusion therapy was effective in 71% (27 of 38 renal units) for the upper urinary tract tumors and that there were 5 cases of severe complication, including sepsis in 2, high fever in 2, and ureteral stricture in 1. Based on the fact that the kidney receives a profuse blood supply and that the renal pelvis and ureter have a thin wall, careful management is mandatory to prevent severe adverse effects and insidious tumor progression.

Bilateral hydronephrosis identified by a local physician brought a 65-year-old man to our hospital. Emergency percutaneous nephrostomy was bilaterally established for obstructive renal failure. After recovering renal function, the patient underwent radical cystectomy under the diagnosis of invasive bladder cancer and the construction of an ileal conduit. The pathology reported well differentiated adenocarcinoma (pT2, pL1, pV1). Five years after the surgery, gross hematuria developed. A computed tomographic scan revealed right hydronephrosis with a solid mass in the upper calyx. The urinary cytology was negative. The patient underwent right nephrectomy in May, 1999. The pathology then revealed well differentiated adenocarcinoma in the renal pelvis and ureter (pT3, pL0, pV0 and pT1, pL0, pV0, respectively). He is alive with mild chronic renal insufficiency with evidence of tumor at ten months after surgery. To our knowledge, this is the first case of metachronous adenocarcinoma of the urinary bladder and the upper urinary tract reported in the Japanese literature.
