Röntgenzystographie

Röntgenzystographie is a medical imaging technique used to visualize the urinary bladder. It involves introducing a contrast medium into the bladder through a catheter and then taking X-ray images. This procedure allows for the detailed examination of the bladder's shape, size, and lining, as well as the detection of abnormalities such as stones, tumors, or structural defects. The contrast medium, which appears white on X-rays, fills the bladder, highlighting its internal contours and any irregularities.

The procedure is typically performed by a radiologist or urologist. Before the examination, the patient's bladder is usually emptied. A local anesthetic may be used to minimize discomfort during catheter insertion. The contrast agent is then slowly injected into the bladder. Once the bladder is adequately filled, a series of X-ray images are taken from different angles. In some cases, images may also be taken after the contrast medium has been drained to assess the bladder wall for residual abnormalities.

Röntgenzystographie is valuable for diagnosing a range of bladder conditions. It can help identify the presence and location of bladder stones, evaluate for urinary tract infections, assess congenital abnormalities, and investigate sources of hematuria (blood in the urine). It is also used to monitor the effectiveness of treatments for bladder diseases. While generally safe, potential risks include infection and allergic reaction to the contrast medium, though these are uncommon. The information obtained from a Röntgenzystographie guides further diagnosis and treatment planning.
