Filter by:This randomized pilot clinical trial studies sildenafil citrate before surgery in improving kidney function in patients with kidney cancer. Sildenafil citrate may help protect the kidney from the side effects of surgery and improve kidney function after surgery.
We are the missing link in clinical trials, connecting patients and researchers seamlessly and conveniently using a mobile health platform to advance medical research. We make it easy for patients to contribute to research for medical conditions that matter most to them, regardless of their location or ability to travel.
Partial nephrectomy (kidney removal) is a standard therapy for clinical T1 renal (kidney) tumors. The goals of surgery are to accurately remove the tumor with no cancer cells at the edge of the remaining tissue, to limit blood loss, and preserve kidney function. The most common technique is to clamp the blood supply to the entire kidney during removal and to surgically repair the tumor bed with suture and agents to stop bleeding. This stops the blood supply to the entire kidney including the healthy tissue, which can cause damage to the remaining tissue due to a shortage of oxygen if left clamped too long. This study uses a microwave pre-coagulation technique using the Certus 140™ to facilitate a bloodless area near the tumor for accurate tumor removal and repair, while avoiding clamping the blood supply, but its effect on the function of kidney adjacent to tumor is unknown. If adequate stoppage of bleeding is achieved using the Certus 140™ with minimal heat spreading to the remaining tissue, clamping and a shortage of oxygen can be avoided. The hypothesis is that microwave pre-coagulation is a safe method for providing the stoppage of bleeding during partial kidney removal.
This clinical trial studies ultrasound elastography in diagnosing patients with kidney or liver solid focal lesions. New diagnostic procedures, such as ultrasound elastography, may be a less invasive way to check for kidney or liver solid focal lesions.
This randomized pilot clinical trial studies body warming in improving blood flow and oxygen delivery to tumors in patients with cancer. Heating tumor cells to several degrees above normal body temperature may kill tumor cells.
The goal of this clinical research is to learn how effective an ultrasound contrast agent, called DEFINITY, is when used during ultrasound-guided surgery to remove part of one or both kidneys.
The purpose of this study is to compare the efficacy and safety of the segmental artery clamping and main renal artery clamping during laparoscopic partial nephrectomy
The purpose of this study is to better understand how effective ablation is for destroying tumor cells in the kidney and whether quality of life is improved for patients. Participation in ARMOR may involve retrospective data collection only, combined retrospective and prospective data collection, or prospective data collection
It is a an open label, multicentric, phase II study assessing the efficacy of everolimus (given per os) as a first line treatment in kidney cancer of bad prognosis. 92 patients will be included (anticipated). The treatment by everolimus will continue until progression, significant toxicity or withdraw of consent
This randomized clinical trial studies the Family Caregiver Palliative Care Intervention in supporting caregivers of patients with stage II-IV gastrointestinal, gynecologic, urologic and lung cancers. Education and telephone counseling may reduce stress and improve the well-being and quality of life of caregivers of cancer patients.
