The significance of kidney cancer diagnosis

The significance of kidney cancer diagnosis: kidney cancer examination and diagnosis: It is not difficult to diagnose kidney cancer based on the clinical data of kidney cancer, but false positive and false negative diagnoses also occur from time to time. Comprehensive and careful analysis is the basis for accurate diagnosis. Next, let us learn more about the common knowledge related to kidney cancer examination and diagnosis.

Kidney cancer testing and diagnosis
1. Patients with typical symptoms such as hematuria, back pain, and masses in medical history and physical examination are not difficult to diagnose, but this type of tumor is often in the late stage. Some patients have very atypical clinical manifestations, and the symptoms are not in the urinary system. In a few patients, the symptoms of metastatic cancer may appear earlier than the symptoms of kidney cancer itself, making diagnosis more difficult.
2. Laboratory examinations include hematuria, anemia and elevated erythrocyte sedimentation rate.
3. Ultrasound scanning is currently the simplest and most non-invasive examination, and can detect renal tumors with a diameter of more than 1 cm.
4. X-ray examination
X-ray examination is the main examination method for renal cancer. Urinary tract plain film can show that the renal shadow on the affected side is enlarged, and calcification may be seen in the tumor. Excretory urography can show that the renal calyx and renal pelvis are compressed, deformed, elongated, and twisted, and can also understand the state of renal function, especially the function of the healthy kidney. When intravenous urography is contraindicated or unclear, retrograde urography can be considered.
