[A case of fused pelvic kidney (lump kidney) with invasive bladder tumor].

A case of fused pelvic kidney, in a 67-year-old woman is presented. The patient also had a bladder tumor that had invaded the bladder wall. The renal anomaly was confirmed by drip infusion pyelography, computed tomography scanning, (CT-scan) and angiography. The CT-scan showed lump kidney with an aplastic right kidney anterior to the sacrum. Two renal arteries derived from the right common iliac artery were demonstrated by pelvic-angiography. The right ureter was not identified during the total-cystectomy. The left ureter was fixed firmly to the surrounding tissues and its free portion was less than 7 cm long. Thus left ureterocutaneostomy was selected for the formation of the urinary diversion.
