Calcification of the cyst wall of a renal cyst is a limited calcified focus of the cyst wall of a renal cyst that develops after healing of inflammation in the intrarenal tissue. Renal cysts with cyst wall calcification are usually detected by CT examination and are usually due to localized infection of the renal cyst. For renal cysts with calcification of the cyst wall, if there is no other clinical manifestation, no special treatment is usually needed. It is recommended to review the examination every six months to one year. If renal cysts larger than 4 centimeters in diameter are found to be accompanied by calcification of the cyst wall, or if the renal cysts compress the ureter, resulting in low back pain, hematuria, hydronephrosis, etc., laparoscopic renal cysts can be performed. Laparoscopic decapitation and decompression of renal cysts can be performed, or renal cyst puncture sclerotherapy can be performed to reduce the local compression of renal cysts, and the changes of renal cysts should be monitored regularly after the operation. When the renal cyst cyst wall calcification should be taken seriously, if other discomfort occurs, timely medical treatment.
