Introduction:

Renal cysts are mainly detected during ultrasound. They may be congenital (associated with genetic disorders or not) or acquired.

Material and methods:

The aim of the study was the retrospective analysis of patients hospitalized in two-years period (2015-2016) with suspicion/diagnosis of renal cysts.

Results:

In the analyzed time 1604 patients were hospitalized, among them 49 children (aged from 1 month to 17 years) met the inclusion criteria. In 30 cases, pateints were admitted to the clinic for the first time, in other cases - again. Among children hospitalized for the first time, there were 14 infants (mean age 4.2 months). Positive family history was noted in 2 children, renal cystic disease were suspected prenatally in 5 cases. Final diagnosis was: autosomal recessive polycystic kidney disease (ARPKD) in 3 children, autosomal dominant polycystic kidney disease (ADPKD) in 1, multicystic dysplastic kidney (MCDK) in 4, connected with ectopia of left kidney in 1, bilateral MCDK in 1, isolated renal cyst in 2, renal hypodysplasia with cysts in 2 children. In 16 older children (mean age 10.1) diagnosed for the first time due to hypertension or abnormality in abdominal USG, ADPKD was diagnosed in 11 children, right MCDK in 4 and left MCDK in 1. In 19 patients hospitalized again (mean age 9.5) the diagnosis was: ADPKD in 4, ARPKD in 6, MCDK right in 4, MCDK left in 3, ADTKD in 1 and medullary sponge kidney in 1. In cases of 23 (47%) described children, chronic kidney disease (CKD) in different stages was diagnosed, in 3 patients kidney transplantation was performed. Acquired cysts were not found.

Conclusions:

Renal cysts are not a common cause of hospitalization (3.1% of our patients), but they require early diagnosis and monitoring of patients due to the risk of CKD development in some cases.
