Inclusion criteria

Inclusion criteria: 1. Informed consent of patients and voluntary participation in treatment research projects. 2. Patients diagnosed with unilateral upper urinary tract hydronephrosis (incomplete, with repeated infection and other complications, but with normal renal GFR on the affected side and the healthy side). 3. Patients who agreed to be randomly assigned. 4. Age 20 to 60. 5. No other disorders affecting renal excretion function at baseline. 6. Qmax > 15ml/s. 7. The patient's serum creatinine level is within the normal range.

Exclusion criteria

Exclusion criteria: 1. Life expectancy < 5 years. 2. To join or plan to join the research of other drugs or medical devices. 3. Patients with iatrogenic or anatomical upper urinary tract obstruction caused by clear etiology, such as calculi and tumors, and without surgical treatment and removal. 4. Tuberculosis, ureteral orifice malformation, pelvic lipomatosis, occlusion and extraluminal ureteral compression. 5. Patients with lower urinary tract stricture or bladder neck contracture. 6. Lower urinary tract dysfunction caused by neurologic bladder dysfunction or other neurologic lesions. Multiple neuropathy (e.g., diabetes). 8. History of lower urinary tract and pelvic surgery. 9. Stress incontinence patients requiring treatment or daily care or use of medical devices. 10. History of intermittent catheter insertion. Patients with acute myocardial infarction, cardiac surgery or cardiac arrest within 180 days did not sign an informed consent. 12. Immunodeficiency (e.g., organ transplantation, leukemia).
