The development of a left renal cyst may be due to the formation of small cavities in the patient's renal tubules during development, leading to the accumulation of urine within these cavities. This accumulation causes the cavities to expand and form simple cysts. Additionally, if the patient experiences infections or develops kidney stones in daily life, resulting in damage to the kidney's surface structure, this may also lead to the formation of a left renal cyst.
