Kidney Stones clinical trials at UCSF

4 in progress, 3 open to eligible people

Showing trials for
  • Accuracy of Ultrasound for Detecting Residual Fragments During RIRS

    open to eligible people ages 18 years and up

    The purpose of this study is to assess the accuracy of ultrasound and traditional fluoroscopy to find the residual fragments before retrograde intrarenal surgery is complete. This would ultimately limit the need for radiation exposure and improve the quality of clinical care given to patients and healthcare teams.

  • Ambulatory Versus Inpatient Percutaneous Nephrolithotomy

    open to eligible people ages 18 years and up

    The goal of the study is to determine if ambulatory tubeless PCNL is safe and effective compared to inpatient PCNL with a nephrostomy tube.

  • Break Wave(TM) Extracorporeal Lithotripter First-in-Human Study

    open to eligible people ages 18 years and up

    This is a prospective, open-label, multi-center, single-arm (non-randomized) study to assess the safety and effectiveness of breaking stones in the upper urinary tract using the SonoMotion Break Wave technology. Up to 30 subjects will be included. The procedure will be performed in a hospital surgical environment as an outpatient (without being admitted) or in a non-surgical environment such as a clinic or office procedure room. The procedure will be performed under varying levels of anesthesia ranging from no anesthesia to general anesthesia (fully asleep). Stones will be limited to ≤ 10 mm for lower pole stones and ≤ 20 mm everywhere else. Safety will be measured by the self-reported occurrences of adverse events, unplanned emergency department or clinic visits, and the need for further intervention. Fragmentation will be measured by self-reported stone passage and a comparison of computed tomography (CT) images before and after the procedure.

  • Video Home Visits for Dietary Counselling

    Sorry, not yet accepting patients

    This pilot study aims to develop a protocol for home video informed dietary counseling with the goal of reducing overall sodium consumption among kidney stone formers. To accomplish this the investigators will: 1)Assess which data available on video visits are most informative to convey patient sodium consumption, and 2) Administer virtual home visits with informed dietary counseling in our intervention arm and compare this to standard dietary counseling looking specifically at the outcome of 24-hour urine sodium excretion results over time. This study will benefit dramatically from the rapid growth of telehealth medical visits as a consequence of the SARS-CoV-2 pandemic, with the ultimate goal to improve and adapt patient dietary counseling for the prevention of kidney stone disease in the new and evolving era of telehealth.
