Study Summary

This trial is testing two different ways to do a nephrostomy on patients with urolithiasis to see which is better, and what characteristics predict success for each approach.

Who is the study for?
This trial is for individuals with large kidney stones (>10 mm) located in the renal pelvis or upper ureter, as confirmed by CT scans. It's not suitable for those who've had previous stone removal from the same kidney, have a current kidney infection, are pregnant, or have an abnormally shaped kidney like Horseshoe or Ectopic kidneys.Check my eligibility
What is being tested?
The study compares two techniques of creating a channel to reach and remove kidney stones: one where access is made going backwards (retrograde) into the urinary system versus another where access is made going forwards (antegrade). The goal is to see which method leads to better outcomes.See study design
What are the potential side effects?
Potential side effects may include discomfort at the site of entry, bleeding, possible injury to surrounding tissues or organs during the procedure, and risks associated with anesthesia.
