Computed Tomography (CT) in Urology

- Kidney stones and urinary obstruction: A non-contrast CT can be used as an additional measure to detect kidney stones and assess urinary flow disorders.

- Tumor diagnostics and staging: Contrast-enhanced CT is used to diagnose urogenital tumors such as renal cell carcinoma, urothelial carcinoma, and testicular tumors, and to assess their spread.

- Trauma diagnostics: In cases of injuries to the kidneys or upper urinary tract, CT provides valuable information about the extent of the damage.

- Vascular imaging: CT angiography can provide detailed images of abdominal vessels, which is relevant for planning surgical interventions.

1. Preparation: In many cases, no special preparation is necessary. If a contrast agent is used, the patient should drink plenty beforehand and possibly remain fasting.

2. Procedure: The patient lies on a movable table that slowly passes through the CT machine. During this time, X-ray images are taken from different angles.

3. Duration: The examination usually only takes a few minutes and is completely painless.

4. After the examination: If a contrast agent was given, one should drink a lot afterward to quickly flush it out of the body.

A CT scan uses X-rays, which are applied in higher doses than in a normal X-ray. However, the radiation exposure is kept as low as possible. The doctor will carefully consider the necessity of a CT to ensure the best possible benefit for the patient.

• Fast and accurate diagnosis: A CT provides detailed images that help the doctor detect diseases early.
• Painless and non-invasive: No needles or surgical procedures are necessary.
• Real-time images: Particularly helpful for assessing blood flow or organ function.

Computed tomography is an important and modern examination method in urology. It helps to accurately diagnose conditions such as kidney stones or tumors and to initiate the correct treatment. The examination is painless, quick, and provides very accurate results.
