Filter by:The primary objective is to determine if 3D modelling shortens total console operation time as a surrogate endpoint for clinical outcomes like perioperative complications and morbidity in robotic-assisted partial nephrectomy.
To engineer immune organoids from pediatric patient tissues using induced-pluripotent stem cells (iPSC)
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 objective of this study is to understand how patients make decisions about treating their kidney masses, and to identify key values and preferences for treating their kidney masses. The study team will develop a decision aid (DA) using the decision-analytic model to communicate personalized benefit/harm estimates to patients and promote patient-centered treatment of renal tumors.
The aim of our study was: a) to evaluate the usefulness of the MR model for renal pedicle exposure and identification of the tumor's exact location during LPN, and b) to evaluate the subjective utility of the MR model as an intraoperative reference tool. Investigators prospectively enrolled 47 patients with LPN between June 2020 and February 2021. Patients were randomly assigned into two groups: the control group (24 patients), who underwent operation with an intraoperative ultrasound (US) control and the experimental group (23 patients), who underwent operation with the aid of the MR model. Randomization was performed using a computerized randomization program and sealed envelopes. Patients were included in the study if they were 18 years of age or older, were able to sign informed consent, and had T1a renal tumors amenable to LPN. Patients were excluded if they were unwilling to participate or did not meet the inclusion criteria. For each patient, investigators prospectively collected demographic data including age, body mass index, clinical tumor size, side, location, and complexity score according to the PADUA scoring system; perioperative data (including time for renal pedicle exposure and time for renal tumor detection and duration of ischemia); pathological data; data on postoperative functional outcome and complications, classified according to the Clavien-Dindo system.
Purpose: The purpose of this study is to evaluate the role of renal mass biopsy on decision-making for patients presenting with clinical T1 kidney tumors. This study also incorporates integrated biomarker study to compare the genomic data obtained through biopsy tissue to genomic information from surgical data.
The aim of the study is the evaluation of the ablation efficiency of the percutaneous irreversible electroporation (IRE) as primary ablation therapy of locally confined renal cell carcinoma (≤4cm, see inclusion and exclusion criteria). The ablation success will be proofed by magnet resonance imaging (MRI) and histologically after partial kidney resection or nephrectomy 4 weeks after IRE. Hypotheses: Kidney tumors ≤4cm can be ablated completely by percutaneous IRE. Surrounded structures and renal tissue can be preserved.
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.
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 pilot clinical trial studies imaging during surgery in diagnosing patients with prostate, bladder, or kidney cancer. New diagnostic imaging procedures, may find prostate, bladder, or kidney cancer
