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.
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.
Bladder+urethra xray: Vcug is a fluroscopic xray stud to demostrate bladder + urethra during filling + voiding. Catheter is introduced into the bladder which is slowly filled with xray contrast material, ideally with antibiotic to avoid causing a uti. Subject can hopefully urinate when bladder is full. Study demonstrates bladder + urethral abnormalities such as bladder reflux, outpouching diverticula, +voiding dynamics.
Xray of bladder and: Urethra. Performed by passage of small catheter into bladder which is filled urographic contrast medium (like a dye) until it is full. Subject then urinates and entire study is monitored by xray fluoroscopy. Will demonstrate bladder reflux or diverticula or any 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.
More uncomfortable: Than painful. Involves passage of a small caliber catheter via urethra into bladder. Bladder will then be filled with xray contrast (dye). She will be asked to urinate when her bladder is full and the study will be monitored by fluoroscopy. Hopefully staff will let you hold her hand whilst catheter is passed and during study. Not as bad as many parents think it will be. Good luck.

Medical, IUI or IVF: Retrograde ejaculation can be caused by injury to the nerves through surgery or from diabetes. Medical treatments can sometimes be used to increase the sphincter pressure of the bladder so sperm will come out instead of back. Otherwise, ejaculating, voiding afterward then quickly processing the sample for use with insemination or ivf is necessary.
