Evaluation of Renal Injury After RIRS Using Shear-Wave Elastography

Starting soon · Not applicable

Conditions studied: Kidney Stone

In brief

This study aims to evaluate changes in renal parenchyma following retrograde intrarenal surgery (RIRS) using shear-wave elastography. Renal elastography measurements will be performed in patients undergoing RIRS for kidney stones on the preoperative day, on the first postoperative day, and on the seventh postoperative day. Postoperative pain scores, perioperative outcomes, stone-free status and complications will also be assessed.
