This study is planned to include patients from S.I. Spasokukotskiy Citi Clinical Hospital with simple renal accidentally discovered cyst. The aim of the study is to evaluate the impact of simple renal cysts on renal function and explore the correlation between cyst's size, parenchymal atrophy, and renal function. After receiving the results, the analysis of the data obtained is carried out. 1. The symmetry of the function of both kidneys is analyzed 2. The relationship between the presence of a simple kidney cyst and a decrease in its function in comparison with a healthy kidney is analyzed. 3. The relationship between the maximum size of a kidney cyst and a decrease in its function in comparison with a healthy kidney is analyzed. 4. The relationship between the volume of the atrophied kidney parenchyma and a decrease in its function as compared with a healthy kidney is analyzed. 5. Correspondence of GFR indices obtained by scintigraphy and by calculation using the Schwartz formula
