How to diagnose kidney cancer, renal cell carcinoma is the typical clinical manifestations of hematuria, mass and back pain, but generally only to the three symptoms of advanced disease only when the same time. Therefore, patients over the age of 40, there any of the above symptoms should attach great importance, especially painless gross hematuria often throughout the first symptom of kidney cancer, it should first be considered and ruled out the possibility of renal tumors. In addition to physical examination together with both hands without mass consultation note kidney area, the common kidney cancer diagnostic measures are:
lB ultrasound examination can be detected in tumor diameter of lcm or more, and the use of non-invasive, can repeat the examination, can accurately distinguish cystic lesions or is solid lesions.
2.CT CT scan not only the correct scanning resolution of cystic lesions is still solid, it is still capable of diseased tissue by measuring the density of the diagnosis, to better reflect the anatomic image of the variation, after application of control agents are still capable of understanding two- renal function, renal cell carcinoma is currently the project has been listed as a routine examination before surgery.
3. Angiography renal pelvis by intravenous excretory urography, not only can see the renal pelvis caused by renal, calyceal pressure situations, such as Talon malformations, petal-like distortion, defects do not develop and so on, and understand the contralateral cases of renal function, which decided to remove kidney disease is an important prerequisite.
4. MR This is the second CT scan after another of new diagnostic techniques. According to statistics, clinical stage renal cell carcinoma magnetic resonance for the correct rate can reach 90%.
5. Renal artery angiography and embolization of renal arteriography in renal cysts and renal tumors have an important role in the identification of the former cyst without blood vessels, small blood vessels around the cyst and neat, often has bow shift; and renal vascular rich, thick, arranged in disorder. Renal artery angiography is currently the general arterial embolization of renal tumors before the diagnosis of a complementary measure, once diagnosed kidney cancer, renal angiography at the same time that line artery embolization. Artery embolization can reduce the tumor, surgery to reduce bleeding and thrombosis proliferation, but also reduce the difficulty of operation.
6. A large number of laboratory tests in patients with renal cell carcinoma after the onset of gross hematuria, usually microscopic red blood cells in urine more or less, some patients can be found in urine cytology cancer cells, but the positive rate is low. Developed in recent years the diagnosis of tumor markers is important to check.
How to diagnose renal cell carcinoma 7. Cystoscopy other attack in the urine can get a glimpse of where the side from hematuria, retroperitoneal inflatable renal angiography and for understanding the circumstances surrounding tissue adhesions also help, select applications.
