- Public TitleTHE KIMONO-STUDY.
- Scientific TitleTHE KIMONO-STUDY: On the development of renal injury in children with a solitary functioning kidney.
- ACRONYMKIMONO (KIdney of MONofunctional Origin)
- hypothesisThe hyperfiltration hypothesis implies that children with a solitary functioning kidney are at risk to develop hypertension, (micro)albuminuria and chronic kidney disease. We aim to develop an individualized risk profile for children with a solitary functioning kidney based on renal parameters, genetics and epidemiological studies.

- Brief summaryCongenital anomalies of the kidney and urinary tract (CAKUT) are the major cause of end-stage renal disease in childhood. One important subgroup of CAKUT-patients consists of children with solitary functioning kidneys. A solitary functioning kidney from childhood can be of congenital origin or can also be acquired after unilateral nephrectomy. Both types of solitary functioning kidney have been associated with an increased risk to develop chronic kidney disease in later life. This risk may be caused due to glomerular hyperfiltration in the reduced number of nephrons following renal mass reduction, as described by Brenner. No new nephrons can be formed after the 34-36th week of gestation, which implies that glomerular hyperfiltration is present in a solitary functioning kidney. Another significant risk factor in the development of chronic kidney disease is the high prevalence of associated CAKUT found in patients with a solitary functioning kidney. Finally, genetic factors that play a role in renal development have incrementally been identified to underlie the solitary functioning kidney. THE KIMONO-STUDY aims to develop an individualized risk profile for children with a solitary functioning kidney by performing studies on the development of renal injury, genetics and epidemiologyl.
