Inclusion criteria

Inclusion criteria: 1. Meets the diagnostic criteria for clinically isolated kidney: (1)Congenital isolated kidney;(2) Acquired isolated kidney (contralateral kidney has been removed for reasons including but not limited to kidney tumor or renal pelvis ureteral tumor, kidney injury, kidney donation, etc.); (3) Solitary functional kidney refers to the condition of contralateral kidney dysfunction, including but not limited to congenital non functional kidney malformation, chronic pyelonephritis, glomerulonephritis, polycystic kidney disease, multiple kidney stones with hydronephrosis, etc. 2.The clinical diagnosis is a patient with ureteral tumor, and the pathological diagnosis of the lesion tissue biopsy or urine cytology is urothelial carcinoma. The pathological diagnosis was made within 3 months before the screening period; 3. Imaging examination and/or pathological staging T2-3; 4.Single lesion = 3cm, or (and) number of ureteral lesions >= 3; 5.I have a strong desire to protect my kidneys; 6.Age range: 18-80 years old, male or female not limited; 7.The patient's general condition is good, with an ECOG score of 1-2 points (Karnofsky score>40); 8.The patient or authorized representative understands and signs the informed consent form.

Preoperative imaging suggests peripheral organ invasion, pelvic or abdominal wall involvement, or lymph node metastasis (N1) and distant metastasis (M1) stage; 2.Preoperative imaging or endoscopic examination suggests the presence of urothelial carcinoma lesions in the renal pelvis and calyx cavity, and complete resection of the upper urinary tract tumor cannot be achieved with simple total ureteral resection; 3.Previous intestinal diseases, abdominal surgery history, etc. make it impossible to perform ileal ureteral replacement surgery; 4.The patient has received infusion chemotherapy, systemic chemotherapy, or immunotherapy in the 6 months prior to enrollment; 5.
