BSUS patients were prospectively enrolled in this study, and non-randomly treated with "balloon dilation +CMUS" and "balloon dilation + tandem DJ stent". Perioperative data of the patients were recorded to compare their efficacy and complications, and the ureteral stent symptom questionnaire was used to compare their impact on patients' quality of life. CMUS and tandem DJ stents were removed after ≥3 months of indwelling. After the removal of stents, the patients' serum creatinine and renal pelvis width were followed up to compare their curative effect on BSUS.
