Comprehensive comparative investigations between HugeMed HU30M 6.3 Fr f-URS and traditional approach f-URS devices in RIRS are lacking in an American population. The investigators aim to compare the outcomes of using the 6.3 Fr f-URS versus traditional approach (other f-URS present in our institution) to treat patients with stone burden ≤ 2.5 cm. The findings of this study will expand on the potential advantages and drawbacks of HU30M in enhancing surgical outcomes and patient safety in RIRS procedures. We hypothesize that the use of the HU30M will result in increased cost savings while providing similar stone free rates when compared to traditionally used f-URS devices.
Males or females ≥ 18 years of age
Patients with ureteral or kidney stones undergoing primary flexible ureteroscopy for retrograde intrarenal surgery
Total stone burden ≤ 2.5 cm
Undergoing bilateral stone treatment during the same procedure
Patients with known genitourinary anatomical abnormalities that would complicate the procedure as determined by the treating investigator
Uncorrected coagulopathy
Patients with urinary diversions
Single group
Ureteroscopy using the 6.3 Fr f-URS hugemed
DeviceAll patients will be counseled on standard treatment options. Treatment options and subsequent care will not deviate from routine care. If they do not enroll in the study, the HU30M may still be used during routine surgery and care. The only intervention specific to the research will involve the use of patient information in describing the results. Participants will undergo RIRS in standard fashion, without deviation from the standard of care. Patients will be brought to the operating room, positioned, and placed under general anesthesia. RIRS will be performed using HU30M 6.3 Fr f-URS. Laser platform (ex: HoYAG or TFL) as well as laser settings will be at the treating investigator's discretion and may be changed during the procedure at their discretion as well, all per standard of care. The initial laser settings and changes that occurred to the settings after the first minute of the case will be recorded.
