Results available when A few minutes to a few days. Interpretation A radiologist examines the flow of urine on the moving X-rays for signs of reflux. It is the only test that can diagnose reflux. It's a good way to determine how well the bladder empties. It requires insertion of a foley catheter.
Some patients are embarrassed about having to urinate in front of a radiology screen.
Factors affecting results Feces or gas in the bowels. Inability to urinate in a steady stream without muscle spasms. If there is a diagnosis of reflux, surgical correction may be recommended, especially for young children and kidney transplant patients. If the test indicates a problem with bladder contraction, further urologic testing may be recommended, or drugs such as urocholine may be prescribed to improve bladder function. In patients preparing for renal transplant, the presence of severe reflux may be an indication that the diseased kidney should be removed before the transplant.
