Chu DI, et al. - Experts compared the operative success, operative time, hospitalization, and postoperative complications of externalized pyeloureteral (EPU) with double-J (DJ) ureteral stents following robotic-assisted laparoscopic pyeloplasty (RALP). Data demonstrated that particularly in younger patients, a viable alternative was provided by the use of EPU stents to DJ stenting with comparable success and complications while avoiding the need for an additional anaesthetic. At baseline, there was a difference in patients receiving EPU stents from those receiving DJ stents. After propensity score weighting balanced these covariates, an association of EPU stents with similar operative success, complications, and operative time to DJ stents was seen.
