Filter by:60 patients ASA I-III, undergoing open nephrectomy will be randomly assigned into one of two groups, namely group A (n=30), where a thoracic paravertebral block will be performed preoperatively and a paravertebral catheter for continuous and patient controlled bolus local anesthetic (ropivacaine) doses will be inserted and group B (n=30) where morphine IV will be administered at the beginning and the end of operation and postoperatively through patient controlled IV doses. NRS scores in static and dynamic conditions, complications, patient satisfaction, oxidative stress (through lactic acid, superoxide dismutase, malondialdehyde) and NGAL pre- and postoperatively, will be recorded.
The investigators are interested in whether or not the use of a mobile health (mHealth) application increases the rate of follow-up compliance among living kidney donors. The investigators aim to test this by randomly assigning living kidney donors to the intervention (use of mHealth application to complete required living kidney donor follow-up at 6 months, 1 year, and 2 years) or control arm (standard of care) upon discharge from their initial donation hospitalization, and tracking follow-up compliance over time. The study population will be approximately 400 living kidney donors who undergo donor nephrectomy at Methodist Specialty and Transplant Hospital (200/year for 2 years). The investigators will also recruit patients from the Vanderbilt University Medical Center into the study, however, these study participants are not a part of the Pilot Randomized Clinical Trial (RCT).
The aim of this study is to determine whether intravenous acetaminophen compared to enteric acetaminophen offers increased efficacy in patients who are scheduled for laparoscopic donor nephrectomy and for patients scheduled for robot-assisted, laparoscopic nephrectomy for cancer at the University of Rochester Medical Center. The standard surgical and post-operative care, including post-operative pain management will not be altered.
Patients with respiratory disease have an increased risk of developing complications perioperatively. The use of regional anesthesia decreases this risk with better postoperative outcome. The aim of this study is to compare the safety and efficacy of thoracic spinal versus thoracic epidural anesthesia for open nephrectomy in patients with obstructive/restrictive lung disease.
This study evaluates the impact of nephrectomy in renal cancer on blood pressure and renal function. The patients will have a follow-up of their blood pressure and renal function until 6 months after their operation.
The purpose of the study is to evaluate patient-specific surgical simulation by permitting pre-operative rehearsals, in the form of the surgeon completing a dry run of the procedure on a model constructed from the patient's radiological studies that replicates every aspect of their organs. The investigators' aim is to evaluate the effectiveness of this form of practice in optimizing intraoperative and postoperative outcomes . The investigators hope eventually to use these rehearsals as a standard study tool for surgical training.
This study evaluates whether using small financial incentives increases patient compliance with nationally-mandated living kidney donor follow-up at 6-months, 1-year, and 2-years after donation. Half of participants will receive a financial incentive (mailed gift card) after completing required follow-up activities (brief questionnaire and lab draw), while the other half will be asked to complete the required follow-up activities but will not receive a financial incentive (current standard of care).
The perirenal fat may alter renal function by secreting fibrotic inflammatory agents when accumulates during obesity. Nephrectomy for renal tumor is a model that would provide tissue samples to test this hypothesis. Renal tumor could itself be responsible for inflammation and fibrosis in its environment. This study aims to measure the influence of the tumor on his kidney Environment and fat and define molecular markers not influenced by renal tumor. The main objective is to compare the inflammation of the perirenal fat taken in two locations in the same patient, in contact and 4 cm from the outer edge of the tumor, each patient as his own control. The secondary objective is to compare the degree of interstitial fibrosis of the renal cortex in the same sampling methods.
Surgery plays a central role in kidney cancer management being the only therapy that offers the possibility of healing the patients. Currently, the partial nephrectomy is a standard technique because it meets the principle of nephron sparing surgery. A partial nephrectomy requires a control of the renal blood flow using a clamp, which can be parenchymal or vascular (pedicular). In France, most of the centers use pedicular clamping. It is well established that this technique results in warm ischemia of the entire healthy parenchyma and can lead to permanent kidney damages. Currently, no study evaluated the impact of parenchymal clamping on the healthy parenchyma. The aim of the investigators study is to evaluate the nephrotoxicity of the healthy parenchyma due to parenchymal clamping during partial nephrectomy. This assessment will be done through a microdialysis technique. The microdialysis probe is directly implanted in the healthy unclamped parenchyma and will allow us to measure in real time, during the surgery, the biological changes related to anaerobic metabolism of renal interstitial space. All those measures will be completed by urinary and plasmatic assessments. Oxidative stress will be assessed using four markers of tubular viability : Interleukin 18 (IL18), Kidney Injury Molecule-1 (KIM-1), Neutrophil Gelatinase-Associated Lipocalin (NGAL) and cystatin C and four parameters of anaerobic metabolism : lactate, pyruvate, glycerol and glucose. This is a prospective pilot study limited to 10 patients included over 12 months. Depending on the results, it will be further developed by a second study comparing parenchymal with pedicle clamping.
Prospective, randomized trial comparing surgical, functional and oncological outcomes between clamp and clamp-less robot assisted partial nephrectomy.
