Criteria for DJ Stent Omission Following Retrograde Intrarenal Surgery Using Flexible and Navigable Suction Sheath: A Prospective Cohort Study
Sponsor: Ain Shams University
Summary
Retrograde intrarenal surgery is widely used for the treatment of upper urinary tract stones. Traditionally, ureteral stents are placed postoperatively to prevent complications such as pain and stone obstruction. On the other hand, it leads to patient discomfort and additional procedures or readmission .This study aims to evaluate whether routine postoperative DJ stenting can be safely omitted following RIRS in appropriately selected patients, without increasing postoperative complications or the need for additional interventions.

flexible ureteroscopy using flexible and navigable suction sheath
This study evaluates the safety of omitting routine postoperative DJ stenting after RIRS in uncomplicated cases, while reserving stenting for patients with predefined risk factors such as ureteric injury or significant residual stones. This selective approach aims to reduce stent-related discomfort and unnecessary procedures without increasing postoperative complications.
