Bilateral urothelial carcinoma of the renal pelvis

Urothelial carcinoma is the 4^th most prevalent malignant tumor after prostate (or breast), lung and colorectal cancers. Urothelial carcinoma of the upper urinary tract is quite rare and accounts for 5–10 % of all cases of this type of cancer. Tumors of the renal pelvis are 2 times more common than tumors of the ureter. A clinical case of a 69-year-old patient diagnosed with urothelial carcinoma of the left renal pelvis T2N0M1, stage IV and metastases into the bladder, right renal pelvis is presented. On 08.06.2023, the patient underwent transurethral resection of the bladder tumor, ureteric orifice, nephroureterectomy on the left, retroperitoneal lymphadenectomy. Between 07.2023 and 10.2023, the patient received 6 cycles of chemotherapy according to the following scheme: gemcitabine 1000 mg/m² intravenously on the 1^st and 8^th days ++ carboplatin AUC 5 intravenously on the 1^st day. Since 11.2023, the patient in receiving maintenance therapy with avelumab.
