Recognizing What to Order - Genitourinary Imaging Flashcards
Recurrent stone symptoms?
Either CT abdomen + pelvis WITHOUT contrast or US kidneys and bladder.
Acute scrotal pain without trauma?
US scrotum with Doppler.
Acute pyelonephritis with complications (diabetes, immunocompromised, prior stones)?
Either CT abdomen + pelvis WITHOUT and WITH contrast or US kidneys and bladder.
Hematuria?
CT abdomen + pelvis WITHOUT + WITH contrast - Study is known as CT urogram.
Hematuria with known parenchymal disease?
US kidneys + bladder.
Renal trauma, blunt with hematuria?
CT abdomen + pelvis WITH contrast.
Renal trauma, penetrating, with or without hematuria?
CT abdomen + pelvis WITH contrast.
Pelvic trauma, blunt?
Abdominal radiographs - Then retrograde cystography or CT pelvis with bladder contrast (CT cystography).
Pelvic trauma, penetrating?
Either retrograde cystogram or CT pelvis with bladder contrast (CT cystography) - Equivalent studies, if already doing CT, then do CT cystogram.
Renovascular HTN?
MRA abdomen WITH contrast or CTA abdomen.
–> If diminished renal function, also can use US kidney with Doppler.
Obstructive voiding symptoms from enlarged prostate?
US pelvis (bladder + prostate) transabdominal. --> If BUN is elevated, then US of kidneys to evaluate for hydronephrosis.
Renal mass of indeterminate benignancy?
Either CT abdomen WITHOUT and WITH contrast or MRI abdomen WITHOUT and WITH contrast.
–> Either CT or MRI is appropriate.
Acute flank pain, suspicion of stone?
CT abdomen + pelvis WITHOUT contrast - Stone search study.
