Randomized Controlled Trial Comparing Relapse Rates Between Standard Ureteroscopic Removal Of Ureteral Stone And Standard Removal With Additional Ureterorenic Clearing Of Non-Symptomatic Stones In The Kidney

Patients with a ureteral (the tube that leads from the kidney to the bladder) stone often
also have small stones in the kidney (frequently visible on CT). If these small kidney stones
are determined to be asymptomatic (not causing any problems or pain), then most urologists
will simply remove the symptomatic ureteral stone and leave the additional stones in the
kidney above. However, the investigators know that the ureteral stone started in the kidney.
This means that the small stones remaining in the patient's kidney may cause problems later.
The purpose of our research is to test if removing small stones from the kidney prevents
future stone episodes

Inclusion Criteria:

- Patients scheduled to undergo ureteroscopic removal of ureteral stone(s) that are
visible on KUB (x-ray) or CT (i.e., calcium stones)

- Current CT scan within the 90-day pre-operative period

- Recurrent (having had previous stones) or multiple stones (simultaneous bilateral
stones)

- Able to give informed consent

- Age 21 years or older

Exclusion Criteria:

- Inability to give informed consent

- Age less than 21 years

- Stones not visible on KUB or CT

- Patients with systemic disease or renal anatomical disorders (RTA, primary
hyperparathyroidism, sarcoidosis, enteric hyperoxaluria, medullary sponge kidney)
