Dr. Zhao Xinju
The left kidney cyst may be a simple renal cyst or an acquired renal cyst. Simple renal cysts are usually caused by congenital incomplete development of lymphatic vessels or infection, leading to lymphatic obstruction and subsequent lymphatic edema. Acquired renal cysts typically occur in patients with kidney failure who undergo dialysis, resulting in a reduction of effective nephrons.
