Retrograde urethrocystography is a diagnostic imaging procedure used to assess the anatomical and functional characteristics of the bladder and urethra. This procedure is particularly important for evaluating the size, shape, and capacity of these structures, which can provide critical information regarding urinary tract health. During the procedure, the physician also investigates the presence of vesicoureteral reflux, a condition where urine flows backward from the bladder into the ureters and potentially the kidneys, which can lead to serious complications if left untreated. The process begins with the cleansing of the urethral orifice using an antiseptic solution to minimize the risk of infection. Following this, a sterile catheter is carefully inserted through the urethra and advanced into the bladder. Once in place, contrast media is instilled into the bladder to enhance the visibility of the structures during imaging. Radiographs, or X-ray images, are then taken as the bladder fills with the contrast material, allowing for the identification of any abnormalities in filling patterns. To further assess for reflux, the patient may be instructed to exert pressure or may have pressure applied to the abdomen. This helps to determine if any urine is refluxing into the ureters and kidneys. After the necessary images are captured, the catheter is removed, and additional radiographs are obtained while the bladder is emptied, providing further insights into the urinary system's function and structure.
