MIP Versus PCNL for Kidney Stone Disease
NCT04767919 · View on ClinicalTrials.gov ↗
Study Summary
The decision to use standard percutaneous nephrolithotomy (PCNL) versus mini-percutaneous nephrolithotomy (MIP) has been a subject of much debate in the urological community. The investigators propose a randomized controlled trial to compare the operative outcomes and complications of mini-percutaneous nephrolithotomy (mini-PCNL) versus standard PCNL for renal stones. The results of this study will help guide the decision making regarding these two procedures in the US population and provide further insight into the utility and safety of these procedures. A cost analysis will be performed, and it is hypothesized that the reusable components of the Storz MIP set will result in lower costs of the mini-PCNL procedure compared to standard PCNL.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT04767919
The ClinicalTrials.gov registry entry for NCT04767919 describes a study currently listed as completed. It is categorized as NA, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 75 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is University of California, San Diego, which has 823 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Kidney Stone appearing as the primary indexed condition, and to 2 interventions — of which Standard Percutaneous Nephrolithotomy (sPCNL) is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT04767919 reports 6 study locations spanning 5 distinct geographic areas — top geographies include Ohio, Arizona, California. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
