Filter by:To compare the outcome of thulium beam coagulation versus suture renorrhaphy for hemostasis of the tumor bed in laparoscopic partial nephrectomy.
The goal of this clinical trial is to better tell apart whether kidney tumors are benign (not cancer) or malignant (cancer) based on a biopsy or imaging tests and ask patients how they feel about decisions they make about treatment of their kidney tumor. The main objectives are: To estimate and compare the diagnostic accuracy of renal mass biopsy alone, PEER (with renal mass biopsy), and 99mTc-sestamibi SPECT/CT (with renal mass biopsy for hot tumors) to differentiate malignant and benign renal tumors. To estimate and compare the diagnostic accuracy of renal mass biopsy, PEER (with renal mass biopsy), and 99mTc-sestamibi SPECT/CT (with renal mass biopsy for hot tumors) to differentiate oncocytoma from chromophobe RCC. Participants will be asked to complete survey questions related to their health and kidney tumor at the start and end of the study. These can be done on paper, electronically, or by telephone.
The investigators aimed to evaluate the role of some findings that can be detected in preoperative radiological imaging of kidney masses in predicting locally advanced disease.
This study evaluates novel surgical approach in treating small renal masses. Half of participants will undergo hypotonic zero-ischaemia partial nephrectomy (standard of care), while the other half will undergo normotonic zero-ischaemia partial nephrectomy (experimental method).
In this trial the investigators want to examine and compare oncological and surgical outcomes of two surgical techniques in a prospective, randomised, single-blind trial. Therefore the investigators are going to include 30 patients with a renal mass who need surgical treatment. When they fulfill the inclusion criteria they get randomised either for robot-assisted partial nephrectomy or laparoscopic partial nephrectomy. Primary endpoint is the oncological outcome (residual tumor classification, TNM classification), secondary endpoints are operation time, time of ischemia, blood loss, pain after surgery, kidney function, complications and hospital stay.
Patients with renal lesions suspicious for renal cell carcinoma (RCC) have a variety of different treatment pathways available to them. Imaging surveillance is being used frequently on smaller renal masses, and radiologists are being asked to biopsy more renal lesions to better guide decision making by urology. This is in large part due to the pathologic grade of renal masses having been shown to correlate with patient outcomes. The World Health Organization (WHO) or Fuhrman grade is the standard grading scale used by pathologists for RCC. The goal of this study will be to correlate contrast enhanced ultrasound findings with the pathologic grade of RCC. Specifically, the investigators hypothesize that tumors with different pathologic grades will show different patterns of qualitative enhancement, as well as different perfusion kinetics.
The aim of this study is to evaluate whether Hemostatic Agents (HA) make a significant clinical difference in patient outcomes when used for Robotic-Assisted Laparoscopic Partial Nephrectomy (RALPN). The result of this trial will determine whether HAs are necessary for use during RALPN or if they can be omitted from the surgical tools available during this procedure. This study has a direct clinical implication on a patient's outcomes following RALPN, specifically whether patients will have better, worse, or unchanged outcomes with RALPN if HAs are used.
