The diagnosis of renal cyst

First, the basic inspection
1. Urine normal urine routine inspection, if capsule of oppression associated with renal parenchyma or intracapsular infection, urine, there will be a small amount of erythrocytes and leukocytes.
2. B-understand cyst number, size, wall situation. And renal tumor and substantive phase identification, as the preferred method. B-typical lesions showed no echo, smooth wall, the border clearly shows that when the wall or irregular echo echo enhanced limitations, should be vigilant against malignant transformation; secondary infection wall thickening, lesions district Fine echo, echo intracystic hemorrhage, increased. When there are multiple cysts imaging tips, and the room should be cysts, polycystic kidney disease with distinction.
3. IVP (ivp) can show parenchymal cysts the extent of oppression, and with the identification of hydronephrosis.
Second, further examination
CT, on the B-scan can identify those valuable, cyst with hemorrhage, infection, malignant, showed no heterogeneity, CT values increase, when CT showed characteristics of the cyst, the cyst can no longer be puncture.
Third, diagnosis
1. Early this disease generally asymptomatic, often in the physical overtime B was found, cyst diameter> 10 cm, caused symptoms. Lumbar mainly abdominal cramping pain intracapsular infection hemorrhage increase.
2. Even in the investigation of the abdomen to the lumbar cystic mass.
3. B extraordinary definitive diagnosis can be suspected when a malignant transformation could be further examination of the methods listed.
4. The disease should be kidney, hydronephrosis, renal cysts room, multi-cystic differential phase.
