Unilateral nephrectomy patients maintained stable kidney function and blood pressure long-term. However, proteinuria and tubular injury markers increased over time, indicating potential late effects of kidney removal.

Area of Science:

  • Nephrology
  • Urology
  • Clinical Medicine

Background:

  • Unilateral nephrectomy (removal of one kidney) is performed for various conditions.
  • Long-term effects on remaining kidney function and blood pressure require thorough investigation.

Purpose of the Study:

  • To assess the long-term impact of unilateral nephrectomy on renal function and blood pressure.
  • To identify factors influencing kidney function post-nephrectomy.

Main Methods:

  • Longitudinal study of 139 patients following unilateral nephrectomy.
  • Assessment of serum creatinine, creatinine clearance, beta 2-microglobulin clearance, and blood pressure.
  • Analysis of correlations between time since nephrectomy, patient age, and renal parameters.

Main Results:

  • Renal function and blood pressure remained stable in most patients during a mean follow-up of 13 years.
  • Proteinuria and N-acetyl-beta-D-glucosaminidase excretion increased over time post-nephrectomy.
  • Lower creatinine clearance was observed in elderly patients or those nephrectomized at an advanced age.

Conclusions:

  • Unilateral nephrectomy is generally safe, with stable kidney function and blood pressure in the long term.
  • Late development of proteinuria and tubular injury markers warrants continued monitoring.
  • Age at nephrectomy may influence long-term renal reserve.
