Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
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

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
kidneys with simple cysts
Patients involve from Citi Clinical Hospital with simple renal accidentally discovered cyst.
CT scan with contrast
CT scan with contrast is necessary to determine the position of renal cysts, their location, and size (determine volume of atrophic parenchyma will be calculated).
Nephroscintigraphy
Nephroscintigraphy is necessary to determine the renal function
contralateral kidneys without cyst
Рatients involve from Citi Clinical Hospital with simple renal accidentally discovered cyst.
CT scan with contrast
CT scan with contrast is necessary to determine the position of renal cysts, their location, and size (determine volume of atrophic parenchyma will be calculated).
Nephroscintigraphy
Nephroscintigraphy is necessary to determine the renal function
