CT urography combines a noncontrast phase to diagnose hydronephrosis and urinary calculi, a nephrogenic phase to evaluate the renal parenchyma for pyelonephritis or neoplastic lesions, and an excretory phase to detect urothelial disease.

Radiation doses for 2-phase CT urography (median DLP 882 mGy.cm, IQR 821) were significantly lower than for exams with inappropriate phases (median DLP 1014 mGy.cm, IQR 1009) (p = 0.02) ( Figs. 5, 6 ).

Optimization of computed tomography urography protocol

This exam has been largely replaced by CT urography. Terminology MATERIAL AND METHODS: The study was based on 102 patients (mean age 66.1+/-14.8 years, range 31-89 years; 30 female, 72 male) divided into five groups (groups A-E) corresponding to the time points at which changes were made to the CT urography protocol. The mean effective doses were estimated using the ImPACT CT Patient Dosimetry Calculator. the CT urography protocol for investigating sus-pected urinary tract malignancy between the years 1997 and 2008, and how these changes have influenced the effective dose.

The French Society of Genitourinary Imaging organised a Delphi consensus conference with a two-round Delphi survey followed by a face-to-face meeting. Consensus was strictly defined using a priori criteria. Forty-two expert uro-radiologists completed both survey rounds with no attrition between the rounds.

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). CT urography is defined as CT examination of the kidneys, ureters and bladder with at least one series of images acquired during the excretory phase after intravenous contrast administration.
