Effects of Obesity Surgery on Renal Function

Imperial College London·observational·Posted Jan 10, 2012·Updated Nov 19, 2020

In Brief

An observational study for Impaired Renal Function. Completed, enrolled 9 participants across 1 site.

Detailed Summary

Increasing risk of impaired renal function as a result of obesity is well known. Early data has postulated that weight loss might improve kidney function, but the evidence is rather limited due to the difficulties in measuring glomerular filtration rate(GFR) after weight loss. Cystatin C, GFR measurement using Cockcroft-Gault (CCG) and Modification of Diet in Renal Disease (MDRD) equations, have all yield conflicting results after weight loss surgery. The study aim to assess: 1. use of 51Cr-EDTA Clearance as the methodological gold standard in evaluating changes in renal function before and after weight loss surgery. 2. the reliability of using MDRD, CCG and Cystatin C in measuring GFR after weight loss surgery 3. the differences in alterations in renal function dependent on the surgical procedures( gastric bypass, gastric band, sleeve gastrectomy). 4. the use of urine albumin/creatinine ratio in detecting alterations in microalbuminuria.
