- Primary Outcome Measures
Name Time Method Overall operative time, defined as the time from induction of anesthesia to the placement of nephrostomy tube in minutes
- Secondary Outcome Measures
Name Time Method <br> 1. Track formation time defined as the time from pelvicalyceal puncture till Amplatz sheath fixation in minutes<br> 2. Fluoroscopy time defined as the time of fluoroscopic x-ray exposure during all steps of the procedure in minutes<br> 3. The stone-free rate (SFR) measured using abdominal NCCT at 2 weeks postoperatively. Stone free status is defined as no visualized stone or residual fragments <3 mm on abdominal NCCT.<br> 4. Re-treatment rate measured from patient notes at 2 years. Defined as the need for more than one session of PNL procedure to treat the renal stone during the trial period.<br> 5. Hospitalization duration in days assessed from the patient notes at discharge<br> 6. Incidence of bleeding and other perioperative complications assessed from patient notes at discharge. PNL complications will be classified and graded according to the modified Clavien classification system<br>
