Is this trial a fit for you?

Likely a good fit

Ideal candidates are living kidney donors aged 18 and older with specific BMI and PRAT thickness measurements.

Probably not a fit

Patients who do not meet the BMI and PRAT thickness criteria or those with significant weight changes may not benefit from this study.

What this trial studies

This observational study aims to investigate whether perirenal fat thickness (PRAT) serves as a marker for visceral obesity and its effects on kidney function and blood pressure in living kidney donors. Participants will include individuals scheduled for nephrectomy, with specific BMI and PRAT thickness criteria. The study will assess PRAT morphology and inflammation, correlating these factors with renal outcomes and hypertension over a period of 4-6 months post-donation. Data will be collected through medical records and various health assessments during a screening visit.

Why it matters

Potential benefit: If successful, this study could improve the management of blood pressure and obesity in living kidney donors, enhancing their long-term health outcomes.

How similar studies have gone: While the specific approach of correlating PRAT thickness with renal outcomes in living kidney donors is novel, similar studies have explored the impact of obesity on kidney function with varying degrees of success.
