NCT04593407
EMR and ESD are both effective and safe and are associated with a very low risk of procedure related mortality when performed for colorectal laterally spreading lesions (LSL). Some kind of LSLs have a low risk of submucosal invasive carcinoma (SMIC) or these foci are found in well demarcated areas of the tumor. This is the case of the non-granular flat elevated (LSN-NG-FE) and the LSLs-G mixed subtypes. The investigators aim to assess if piecemeal EMR (the older technique) for LSLs-G mixed type \> 30 mm and LSLs-NG FE type \> 20 mm is not inferior to ESD (the new treatment) for the need of additional surgery in the mid-term.

This is a prospective pilot study examining the couple's dyadic attitudes from diagnosis to 24 months later when one member is affected by illness and the adaptive strategies the couple employs when stressful events occur.
NCT02075684
The purpose of this research study is to create a prospectively maintained, multicenter database of patients undergoing renal biopsy for renal masses performed percutaneously (through skin), via an 18 gauge biopsy needle (.048 inches). In this database, the investigators will collect and maintain the data from the biopsy procedure. This will allow us to evaluate our experience with this procedure as well as to participate in multi-institutional collaborative studies in the future. At University of California Irvine, the investigators routinely biopsy patients with renal masses under real-time ultrasound control. Percutaneous renal biopsy under ultrasound guidance is a routine procedure performed to diagnose renal mass histopathology. The safety and efficacy of this procedure has been well documented in the literature. The indications for percutaneous renal biopsy have expanded as there has been a substantial increase in the number of renal masses that are being diagnosed, and the acceptance of percutaneous biopsy continues to expand in parallel. The biopsy procedure is part of your normal standard of care and if not being done for this research project.
