Urinary problems: A retrograde urethrogram is when a tiny catheter is put into the opening of the urethra (penis in males) and pictures are taken as the dye is injected backwards. A voiding study is the opposite, contrast is put into the bladder with a catheter and pictures are taken as the patient pees the contrast out.
