The divergent ray sign is a pathological sign that can be detected with retrograde urethrography. This means that when conducting an X-ray examination of the urethra using a contrast agent, narrow shadows may be detected that diverge from one point. This symptom may indicate the presence of perforation of the urethral wall, which can be caused by urethrovenous reflux - the reverse flow of blood from the bladder into the urethra.
The radiating ray symptom can be caused by a variety of reasons, such as infection, injury, cancer, and some urinary tract diseases. For example, a urinary tract infection may cause swelling and inflammation of the urethral wall. In this case, the contrast agent may not pass through the dead tissue and form a narrow shadow that will diverge from one point.
If the urethra is injured, the wall may rupture, which can lead to the symptom of divergent rays. Also, urethral cancer can cause the formation of a narrow canal and the appearance of a symptom of diverging rays during retrograde urethrography.
To diagnose the symptom of divergent rays, it is necessary to perform retrograde urethrography. During this test, the patient is injected with a contrast agent into the bladder and then monitored using an X-ray machine as it passes through the urethra. If a radiating ray sign is observed, this may indicate perforation of the urethral wall and the need for further evaluation and treatment.
In general, the diverging ray symptom is an important diagnostic sign that can help identify various diseases of the urinary tract and take measures to treat them.
The dehiscence sign (shadow migration or Lehmann's sign) is a sign that can be detected when diagnosing early stages of penile cancer or bulbourethral cancer. A sign of dehiscence means that there are signs within the pelvic floor that indicate a possible delay
