Enhanced CT in the diagnosis of renal carcinoma and renal pelvis carcinoma

Enhanced CT in the diagnosis of renal carcinoma and renal pelvis carcinoma.  Renal cancer and renal pelvic cancer are enhanced with 128-slice spiral CT, which has high diagnostic accuracy and effective differential diagnosis, which is convenient for the formulation and implementation of the next treatment plan, and is worthy of promotion and use in the clinic.

In recent years, the incidence of renal tumor diseases has been increasing. Among them, renal cancer and renal pelvis cancer are more common, which have a direct impact on the health and life safety of patients. The surgical methods, preoperative staging, and prognostic evaluation of different types of diseases are different. Therefore, a reliable and feasible diagnosis method as soon as possible is the key to ensuring the treatment and prognostic effect.

In terms of disease diagnosis and identification, imaging examination methods are the main method. Spiral CT enhanced scanning has a certain role in the diagnosis of tumor diseases. Renal pelvis cancer is a oligovascular tumor, which is significantly different from renal cancer. Obvious characteristic manifestations can be seen through CT auxiliary examination. , Which is conducive to the identification of diseases and further development of effective treatment plans.

Renal cancer and renal pelvic cancer are common multiple diseases, which can occur in all age groups, and are mainly middle-aged and elderly. Renal cancer originates from the renal tubular epithelium and occurs in the renal parenchyma. The size of the tumor is closely related to the prognosis. Small renal cancer treatment The difficulty is small and the postoperative prognosis is good. In terms of disease treatment, surgical resection is the main treatment. However, early renal cancer is mostly without specific symptoms, and most patients are found accidentally during routine physical examination.

Renal pelvic cancer is mainly manifested by intermittent painless full-course hematuria, and can also be seen with low back pain, abdominal mass, and urinary tract irritation. Renal pelvic cancer exhibits intrarenal pelvic space occupying in the early stage, and it is slightly enhanced after enhancement. Reliable diagnosis methods are extremely important as soon as possible, and are directly related to disease treatment and prognosis.

128-slice spiral CT enhanced examination has the advantages of simple operation, non-invasive, reproducible, and high resolution, which can clearly show the lesions, which is beneficial to the clinical staging of the disease and the formulation of surgical methods [4-5], the extent of tumor invasion and CT signs of renal pelvic tumors It is directly related, and the inspection can also well show lymph node metastasis (peri-renal infiltration, regional lymph nodes).

Spiral CT enhanced scan showed that kidney cancer showed a gradual growth. It can directly invade the renal calyx, renal pelvis and ureter, and often invade the renal vein. Early blood metastasis can be seen, such as the contralateral kidney, bone marrow, lung, etc., most of which have high blood supply. The lesion, enhanced scan showed moderate to obvious enhancement, with calcification.

Renal pelvis cancer can occur in any part of the renal pelvis. Tumors of the ureter and bladder may also appear at the same time or successively, with fewer blood vessels. The enhanced scan showed mild enhancement and less calcification.

Renal cancer can be seen with round, round, irregular shaped lesions, iso-density, slightly higher density or slightly lower density, part of the renal calyx and renal pelvis are compressed and deformed, there are necrosis, cystic transformation, a few calcifications, and the early unevenness of the enhanced scan strengthen.

Among renal pelvic cancers, 72.22% were intrarenal pelvic masses, intracavitary masses, with clear or fuzzy boundaries, uneven or uniform density, and 27.78% infiltrating renal parenchyma, the masses invaded the renal parenchyma, the contours were moderate or slightly deformed, and some delayed scanning The filling defect of the contrast medium in the renal pelvis can be seen.

Therefore, renal cancer and renal pelvic cancer are enhanced with 128-slice spiral CT, which has high diagnostic accuracy and can effectively differentiate the diagnosis, which is convenient for the formulation and implementation of the next treatment plan, and it is worthy of promotion and use in the clinic.
