A typical CT urographic protocol has three phases that allow complete evaluation for the most common urologic causes of hematuria, that is, calculi, renal masses, and urothelial tumors (Fig. 1A, 1B ). The optimal combination of unenhanced, corticomedullary phase and nephrographic phase imaging depends on the context; suggestions of protocols are provided for eight different clinical situations. Conclusion: This expert-based consensus conference provides recommendations to standardise the imaging protocol for computed tomography urography.

1A, 1B ). Just prior to scanning the patient, give 1-2 cups of water in order to distend the stomach. Split bolus technique: The patient is given 35 mL of intravenous contrast and 100 mL saline after the non-contrast exam, but prior to the imaging of the mixed nephrographic/exretory ("Urogram") phase.

In the most general sense, complete CT urography includes a nonenhanced phase, a contrast-enhanced phase, and an excretory phase . studies that CT Urography (CT abdomen and pelvis without and with intravenous contrast) may not be warranted in specific patient cohorts, particularly young individuals without risk factors for urinary tract malignancy, who may be evaluated with a CT exam without contrast only (CT renal stone protocol). CT urography (CTU or CT-IVU) has now largely replaced traditional IVU in imaging the genitourinary tract. It gives both anatomical and functional information, albeit with a relatively higher dose of radiation. A Computed tomography urography (CT urography or CT urogram) is a computed tomography scan that examines the urinary tract after contrast dye is injected into a vein.

CT UROGRAM / HEMATURIA PROTOCOL: NOTES: • Use at least 22g needle • Follow GFR and Metformin protocols for contrast studies • LMP on pts of child-bearing age The optimal combination of unenhanced, corticomedullary phase and nephrographic phase imaging depends on the context; suggestions of protocols are provided for eight different clinical situations. Conclusion: This expert-based consensus conference provides recommendations to standardise the imaging protocol for computed tomography urography. During a CT urogram.

It also is important to determine whether CT urography is the appropriate imaging modality. Depending on the clinical scenario, multiple phases may not be required, and therefore the radiation dose can be reduced . For example, single-phase nonenhanced CT (not CT urography) is generally adequate to diagnose stones in the acute clinical setting. “The CT urogram is most commonly performed as a three- phase computed tomography technique used to evaluate the kidneys and urinary collecting system. The three phases most commonly include a non-contrast phase, a nephrographic phase scanned at 80 to 120 s delay, and an excretory phase scanned at 10–15 min delay.” studies that CT Urography (CT abdomen and pelvis without and with intravenous contrast) may not be warranted in specific patient cohorts, particularly young individuals without risk factors for urinary tract malignancy, who may be evaluated with a CT exam without contrast only (CT renal stone protocol).
