Brief Summary

The objective of the study is to compare the stone free rates with ureteroscopy utilizing the ClearPETRA suction ureteral access sheath, and mini-PCNL; both procedures and ClearPETRA sheaths are standard of care and are used regularly for stone treatment. Our primary objective is to assess the complete stone free rate with both procedures.

Eligibility Criteria

Inclusion Criteria: * Patients 18 years or older * Have a CT scan showing renal stones 1-3cm in length * Patients who will be able to read, understand, and complete patient questionnaires Exclusion Criteria: * Pregnant individuals * Those with anomalous renal anatomy * Patients with a urinary diversion (ex: Ileal conduit, reservoir, bladder substitute, etc.) * Any condition rendering patient medically unfit to undergo either procedure (Bleeding diasthesis) * Patients who lack decisional capacity * Patients who are non-english speakers\* * Non-recruitment of non-english speakers is due to the study being a small pilot study that is used to assess the stone free rate for patients treated with a ureteroscopy or mini-PCNL using ClearPETRA suction access sheaths in a small portion of our patient population seeking treatment for stones. The team also does not possess the bandwidth or personnel to consent patients who are non-English speaking.
