Mannitol Use During Partial Nephrectomy Prior to Renal Ischemia and Impact on Renal Function Outcomes
NCT01606787 · View on ClinicalTrials.gov ↗
Study Summary
The purpose of this study is to determine if a medication called mannitol, can help the kidney maintain its function after kidney surgery. Mannitol is used to cause an increase in urine production (it is a diuretic). For many years, mannitol has been given to patients in the hope it would improve the kidney's circulation, and in doing so reduce the impact of the surgery on the kidney. Mannitol is given during the surgery before the blood supply to the kidney is stopped. The blood supply to the kidney is stopped in order to minimize any blood loss during the removal of the tumor, and also to assist the surgeons view of the kidney anatomy. Once the tumor is removed the blood supply to the kidney is resumed. Sometimes a side effect of this temporary reduction in blood supply to the kidney is the loss of some kidney function. This may happen either in the short term (right away) or long term (months or years later). In studies done on animals, mannitol was able to lessen this damage to kidney function. However, no human study has ever confirmed that mannitol has the same helpful effect in humans. There is some suggestion that it may have no effect. Because sufficient research has yet to be done on humans, many surgeons do not give mannitol. A recent study, conducted at Memorial Sloan Kettering which looked back at patients who had undergone partial nephrectomies, an operation where only the portion of the kidney that contains the tumor is removed and enables the normal, unaffected portion of the kidney to be preserved. The results of this study demonstrated no significant difference in kidney function when the investigators compared patients who were given mannitol to those who were not. The investigators hope that this study will help clarify the effectiveness or not of mannitol on kidney function. During the surgery to remove the kidney tumor, patients will receive either mannitol or a placebo. A placebo, is a harmless medication that has no effects. The impact of ma

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT01606787
The ClinicalTrials.gov registry entry for NCT01606787 describes a study currently listed as completed. It is categorized as Phase 3, 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 210 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Memorial Sloan Kettering Cancer Center, which has 2,280 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 Renal Cancer appearing as the primary indexed condition, and to 2 interventions — of which placebo 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: NCT01606787 reports 1 study location spanning 1 distinct geographic area — top geographies include New York. 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.
