Creatinine clearance and kidney size in Balkan endemic nephropathy patients.

Abstract

BACKGROUND/AIMS:

Symmetrically shrunken kidneys have been considered as one of the characteristics of Balkan endemic nephropathy (BEN), but there is no agreement when the shrinking does occur in the course of the disease. In the present study, the relation between creatinine clearance (Ccr) and kidney length was compared between the patients in the early phase of BEN and other renal diseases.

METHODS:

The study included 84 patients with BEN (39 males, aged 54 +/- 12 years), 31 patients with other renal diseases (15 males, aged 54 +/- 14 years) and 15 healthy subjects as controls. Only the patients with Ccr above 90 ml/min were included into the study. The kidney length was measured by sonography using sector sound of 3.5 MHz.

RESULTS:

In healthy controls and patients with renal disease other than BEN, Ccr varied between 90 and 177 ml/min, and only 3 patients had Ccr above 150 ml/min. On the contrary, 15 (18%) BEN patients had Ccr between 90 and 120 ml/min, and 37 (44%) BEN patients had Ccr above 150 ml/min. Sonographically measured kidney length of all healthy subjects and patients with renal diseases other than BEN was above 10.5 cm. Out of 84 BEN patients, 21 (25%) patients had kidney length less than 10.5 cm.

CONCLUSION:

BEN patients in the early phase of the disease had significantly higher Ccr and smaller kidney in comparison to the patients with other renal diseases.
