Summary

This trial is testing how well ultrasound works to find kidney stone fragments, compared to the current standard (fluoroscopy).

Who is the study for?
This trial is for adults over 18 with diagnosed renal or ureteral stones scheduled for retrograde intrarenal surgery (RIRS). It's not suitable for patients having bilateral stone removal, those who refuse consent, pregnant women, kidney transplant recipients, individuals with ectopic kidneys, or if pain can't be managed in the ER.
What is being tested?
The study aims to compare the effectiveness of ultrasound versus traditional fluoroscopy in detecting remaining stone fragments during RIRS. The goal is to reduce radiation exposure and enhance care quality for patients and healthcare teams.
What are the potential side effects?
While the trial focuses on imaging techniques rather than medications, potential side effects may include discomfort from ultrasound application or complications related to incorrect detection of residual stones.

Trial Design

2Treatment groups
Experimental Treatment
Active Control
Group I: UltrasoundExperimental Treatment1 Intervention
Before completing retrograde intrarenal surgery, a complete endoscopic examination will be performed along with ultrasound by the same endourologist to determine the size of the largest residual fragment.
Group II: FluoroscopyActive Control1 Intervention
Standard of care, control Before completing retrograde intrarenal surgery, a complete endoscopic examination will be performed along with fluoroscopy by the same endourologist to determine the size of the largest residual fragment.
