Renal cyst is a general name of cystic masses with different sizes in the kidney. The common renal cysts can be pided into adult type polycystic kidney, simple renal cyst and acquired renal cyst. If renal cyst symptoms are large cysts, renal parenchymal compression, can be percutaneous drainage, or laparoscopic decompression. Simple renal cysts may originate from retention cysts in immature glomeruli, or from inflammation and ischemia induced obstruction of the tube system.
Kidney stones and calcification within the kidney: if the patient does not pay attention to their diet, then it is easy to lead to kidney stones. The possibility of combined calculus should be considered when the patient is suffering from aggravated pain, twisting or internal hematuria.
Influence kidney function: if the patient cyst is small, also cannot ignore its existence, has the kidney cyst patient to have to check regularly, once discovered increases, immediately goes to the kidney disease hospital to seek the regular treatment. Otherwise, renal cysts will continue to increase, but also affect the kidney function, and accompanied by urinary protein, urine, car, hypertension, renal dysfunction, complications, severe cases will cause renal failure, even uremia.
Grow up into the renal sinus cyst wall: simple renal cyst by a thin layer of fibrous tissue covered with a layer of squamous epithelium, containing grass yellow liquid. A small number of cysts contain bloody fluid. After infection, the wall may thicken and contain viscous liquid. A cyst near the renal hilum and renal sinus, which grows into the renal sinus, is called a para renal cyst. It may be a cyst developed from lymphatic cyst or residual tissue of the renal embryo.
Urinary tract infection: This is one of the most common complications of renal cysts in female patients. Cystitis, pyelonephritis, cyst infection and perirenal abscess are included. The appearance of white tubular urine and rapid response to conventional anti infective treatment are beneficial to the diagnosis of pyelonephritis, while positive blood culture and tenderness of some sites are prone to cyst infection, and CT can find infectious cysts.
