Examination contents confirmed for kidney cancer

People may be a little afraid when talking about kidney cancer, because this disease is a malignant tumor disease. The occurrence of the disease not only brings pain to the patient, but also brings great health hazards to the patient. Therefore, for kidney cancer, people must pay attention to timely examination and treatment after the disease.

1. X-ray examination
X-ray examination is one of the main examination methods for kidney cancer and is a major basis for early diagnosis. In particular, with the continuous updating of equipment technology, the accuracy of X-ray examination has also been significantly improved. When using X-ray examination to examine the kidney, the vast majority of renal cancers can be seen as space-occupying lesions on the pyelogram. Only a very small number of tumors that are very small or close to the renal capsule and do not cause the renal pelvis and calyces to be compressed and deformed cannot be displayed. SKINNER et al. observed that among renal space-occupying lesions with symptoms such as hematuria, renal cancer is the most common cause; and among 940 cases of asymptomatic renal space-occupying lesions, renal cancer accounted for only 2%, and other malignant tumors accounted for 3%, most of which were renal cysts.
(II) Laboratory tests Hematuria is an important symptom. The initial diagnosis of renal cancer is based on clinical manifestations. It has typical symptoms such as hematuria, back pain, and lumps. A completely normal urine routine test cannot rule out renal cancer. Among the 64 cases of renal cancer with more complete data, 28 cases had completely normal urine routine tests. Unless renal cancer has invaded the renal pelvis, urine cytology has little diagnostic value for renal cancer. Because its positive rate is not high. Although most renal cancer patients have elevated or positive results in erythrocyte sedimentation rate, urine lactate dehydrogenase, serum alkaline phosphatase, serum C-protein reaction, etc., they are all non-specific tests and have little diagnostic value for renal cancer.
