What is question? Cath in bladder, filled with contrast, urinate and get x-rays. Can show reflux and urethral abnormalities.
Uncomfortable. Passage of catheter is not very pleasant. Radiologist can use Lidocaine anesthetic gel. Voiding during and first void after study may sting a little. Essentially not painful. Request addition of antibiotic like gentamicin to the xray contrast fluid used to reduce risk of introducimg a uti.
My take. .. VCUG is a special X-Ray exam to visual if one has bladder-to-ureter / kidney reflux (backflow) or urethral stricture while voiding. For details of its current or evolving indication, techniques, alternatives, etc. Over the past 2-3 decades, ask the radiologist timely.
Cystografin contrast. Is the "dye" used, it is introduced through a catheter and is not medication. I personally have gentamicin 80mg added to the cystografin before instillation into bladder to reduce the mild risk of causing a UTI to virtually nil.
Urethrogram 2 ways. Urethra filled by retrograde instillation of x-ray contrast, in males, through a Foley catheter inflated just inside urethral opening or with a special retrograde urethrogram device attached to a syringe filling urethra and bladder until bladder full & patient voids. Or in both sexes bladder filled via a catheter which is then removed & urethra then filled from below by syringe. Best urethral pics.
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.
Dye to &from bladder. Retrograde urethrogram performed be retrograde instillation of urographic contrast medium (dye) from urethral meatus (opening) backwards up the bladder. Voiding cystourethrogram is performed by having a small catheter passed up urethra into th bladder which is then filled with contrast until full and subject then urinates whilst entire study is monitored by xray fluoroscopy.
Fluoroscopic study. Fluoroscopic imaging of bladder and urethra. Usually small catheter is placed through urethra into the bladder. This hurts slightly for a few seconds. Contrast material is placed by gravity via catheter into bladder filling up bladder until patient gets urge to void. Patient then is also imaged voiding.
Test bladder functio. Test for bladder function, done typically with contrast to evaluate for ureteral reflux or other neurogenic bladder issues.
VCUG. Voiding cystourethrograms is an xray test of the bladder taken during peeing (voiding)...It evaluates the bladder and urethra for conditions like reflux and other bladder conditions.
Lower UT X-Ray. Voiding cysto-urethrogram or VCUG is an xray study of bladder and urethra. Performed by instilling radio-opaque contrast medium, via a small caliber catheter, into the bladder. Subject then empties their bladder as the catheter is removed or around the catheter. Study is monitored by fluoroscopy. Anatomy of bladder and urethra, as well as ureter if reflux present, is demonstrated.
