Long Term Outcome of Congenital Solitary Kidney (CSKP)
Congenital solitary kidney (CSK) is a disorder caused by an abnormal development of one of the two kidneys. The reported incidence ranges between 1:450-3200. It is debated whether CSK is a benign condition or not. A variable risk of developing proteinuria (11-27%), hypertension (0-60%) and chronic kidney damage (3.5-30%) is described. This knowledge derives mainly from retrospective studies performed in tertiary medical centers which is difficult to compare for the following reasons: the number of individuals evaluated, the length of follow-up and the outcome studied.
The aim of this longitudinal study is to assess, in a cohort of children with congenital solitary kidney, during a 10 year follow-up period: 1) the rates of developing proteinuria, hypertension and chronic kidney disease and the corresponding potential prognostic factors. 2) the role of new biomarkers of glomerular (Cystatin C) or tubular damage (NGAL, NAG, B2-microglobulin) in predicting the appearance of chronic kidney damage.
