Risks and Benefits of Postoperative Double-J Stent Placement After Ureteroscopy (URS): Results From the Clinical Research Office of Endourological Society URS Global Study

Double-J stent placement following stone removal by URS is common and recommended in many cases but debatable in others. In this study the risks and benefits of postoperative double-J stent placement in URS stone treatment procedures undertaken in current clinical practice, are examined.

The CROES URS is a prospective, observational, international, multicentre study in which patients who were candidates for URS as primary treatment or after failure of prior treatment for ureteral stones and renal stones. Baseline, intraoperative and postoperative data were collected. Predictors and outcomes of post-operative stent placement were analysed by inverse probability weighted regression adjustment of the relationship between a Double-J stent placement and outcomes (Complications, readmission (including retreatment), and length of hospital stay) Results: Significant predictors of postoperative double-J stent placement in URS treatment of ureteral stones were intraoperative complications, impacted stones, operation time, stone burden, age, presence of a solitary kidney and stone free rate. In renal stone treatment the predictors identified included operating time, age, preoperative stent placement, anticoagulant use, presence of a solitary kidney and intraoperative complications. In both ureteral and renal stone treatment groups, postoperative placement of a double-J stent resulted in significantly fewer postoperative complications (p < 0.001) compared with patients who did not receive a stent.

Patient- and procedure-related variables were identified that may enable an individualised approach to postoperative stenting resulting in improved clinical outcomes in urological stone treatment by URS.
