Hypothesis

The study investigates the correlation between renal structural parameters and renal function in pigs.

Conclusion

The study suggests that while structural parameters correlate with renal function, precise prediction of renal function from a single parameter is challenging.

Supporting Evidence

  • The correlation between structural parameters and skGFR was above 0.60 and highly significant.
  • The best correlation was found between cortical volume and skGFR.
  • Prediction of skGFR from structural parameters was shown to be imprecise.

Takeaway

The study looked at how the structure of pig kidneys relates to their function, finding that while they are connected, it's hard to predict kidney function just from structure.

Methodology

Twenty-four pigs underwent skGFR measurements and nephrectomies, with structural parameters estimated using stereological procedures.

Limitations

The study faced challenges in precise prediction of renal function from structural parameters due to biological and methodological variances.

Participant Demographics

Danish Landrace female pigs, n = 24, weighing approximately 29.5 kg.
