Comparison and Evaluation of USSQ, OABSS, and the Drainage/Anti-reflux Effect Between Three Kinds of Ureteral D-J Stents in Patients Who Underwent URL

Indwelling double-J ureteral stent (D-J stent) are routinely placed in patients who received ureteroscopic lithotripsy (URL) in Xinhua Hospital Urology Department. At present, three types of D-J stents, namely Cook/Kang Yi Bo(KYB)/Urovisionare are used, and usually removed in the day ward four weeks after surgery. This study intends to randomly divide patients with urolithiasis based on the preoperative OABSS (overactive bladder symptom score) questionnaire into three groups, namely Cook D-J stent group, KYB anti-reflux D-J stent group, Urovision trigonal D-J stent group, with corresponding D-J stent indwelled for 4 weeks respectively. The patient's USSQ ureteral stent symptom questionnaire）scale and OABSS scale were collected at 1 week, 4 weeks (before the removal of D-J stents), and 5 weeks (1 week after removal of D-J stents) after URL operation, and the D-J stents removed from the patients were collected, and their drainage and anti-reflux effects were measured in vitro.
