Fistulograms: An Advanced Diagnostic Tool
When it comes to obtaining a comprehensive image of a fistula, a fistulogram proves to be an invaluable tool. This specialized x-ray procedure involves the injection of a dye into the fistula, enhancing its visibility in x-ray images. Depending on the location of the fistula, the dye is administered either through a catheter if it connects to the exterior of the body or via the anus if it is located in the rectum. By capturing x-ray images from various angles, doctors are able to gain a multi-dimensional understanding of the fistula’s structure and location.
Intravenous Pyelogram: A Diagnostic Tool for Bladder Fistulas
An intravenous pyelogram is a commonly used X-ray procedure for diagnosing bladder fistulas. Prior to the procedure, patients may be instructed to adhere to a clear liquid diet or fast completely. This precaution is taken to ensure that the colon is free from any stool that may obstruct the surgeon’s visualization of the bladder during the X-ray. The process involves the injection of a dye into a blood vessel, typically in the arm, followed by the capture of several X-ray images from various angles to obtain a clear and comprehensive view.
