A 78-year-old woman presented with macroscopic hematuria. We diagnosed giant hydronephrosis with a left ureteral stone and multiple renal pelvic carcinoma cT3N0M0 tumors.
Open nephroureterectomy proceeded via a peritoneal approach, and 8,600 mL of urine were collected from the renal pelvis. The pelvic carcinoma was histologically confirmed as a rare giant cell variant with high malignant potential. The same variant was found in the upper ureter where a 15-mm stone had lodged. We considered that this was due to rapid progression of the renal pelvic giant cell carcinoma and hydronephrosis during the month before surgery.
Multiple lung and bone metastases occurred after three courses of gemcitabine/cisplatin combination chemotherapy as postoperative adjuvant therapy. Therefore, radiotherapy for bone metastasis and gemcitabine/paclitaxel combination chemotherapy were performed concurrently.
