What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Presence of ureterohydronephrosis | Ureterohydronephrosis represents the augmentation of the diameter of the ureter (more than 10 millimeters) and the renal pelvis (more than 30 millimeters), which can be measured on imaging such as abdominal ultrasound, CT scan, or MRI. Whenever the ureter and the renal pelvis meet these criteria on preoperative imaging, the patient will be labeled as having ureterohydronephrosis. | Before surgery | 
| Presence of abdominal pain | Flank pain (pain in the upper abdomen or back) | Before surgery | 
| Presence of urinary calculi | Urinary calculi can be diagnosed on an abdominal X-Ray, an abdominal Ultrasound or an abdominal CT scan | Before surgery | 
| Presence of abnormal nuclear renal scans | Nuclear renal scans are abnormal when there is a difference of filtration of more than 40% between the kidneys | Before surgery | 
| Presence of urinary tract infection | Urinary tract infection associated with ureteropelvic junction | Before surgery | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Postoperative pain | Mean Digital Pain scale | After surgery and before discharge home, up to 20 days | 
| Postoperative complications | Pyelonephritis | Through study completion, an average of 2 years | 
| Operation time | anesthetic and operating time | During surgery | 
| hospitalization length | hospitalization length | From admission to discharge home, up to 20 days |
