“…Calculi composed of matrix or excreted medications, such as Indinavir, are not radio-opaque on CT. These appear as soft tissue density filling defects (15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30), and therefore can be missed on unenhanced CT KUB; CT urogram with intravenous contrast may be necessary for their identification.…”

In this article we review the computed tomography imaging features of renal and ureteric calculi, the secondary signs of renal tract calculi and their possible complications. Most calculi appear as high-density foci due to their composition, whereas other signs that may be appreciated include the soft-tissue rim sign in the ureter, upstream renal tract dilation and peri-ureteric or peri-renal stranding. The most accurate means of measuring a calculus is in the coronal plane on bone windows. We also provide a systematic approach to interrogating computed tomography of the kidneys, ureter and bladder for the urologist, with examples of other conditions that may present as renal colic and are apparent on computed tomography. Level of evidence: Not applicable as no original research is being proffered.

“…However, ultrasound is inadequate in quantifying the stone burden and generally does not permit differentiation on intact stones from fragmented stones. " ( 7 ) Magnetic resonance imaging avoids the hazards associated with ionizing radiation. However, calcium generates minimal signal and visualization refl ects secondary effects such as edema or obstruction rather than the calculus itself.…”

Acute renal colic is an incapacitating condition. Advances in understanding the pathogenesis of calculi and their detection and treatment require a new approach to aeromedical risk assessment. Can this new information support the stratification of aeromedical risk into "High" and "Low" categories, and fulfill the paramount responsibility of the Civil Aviation Safety Authority, Australia's aviation regulator, which isthe maintenance of aviation safety? This article reviews the epidemiology of calculi and finds 2-10% annual risk of a symptomatic event following incidental detection of a calculus. While calculi 4 mm or less in size may not require surgical intervention, this does not equate to a pain-free passage. Similarly, calculus recurrence rates may vary in different anatomical locations, but no location can be considered "safe." The recognition of parenchymal calcification and Randall's plaques as precursors to the development of calculi places such individuals at elevated risk of developing calculi. More recently evidence has supported a link between metabolic syndrome and calculus formation. In an occupational group where there is potential for elevated radiation exposure, appropriate imaging is of particular importance. CT, X-ray, and ultrasound modalities are reviewed with recommendations presented for aeromedical assessment and surveillance based on identification of those at high risk of colic and minimization of investigational radiation exposure.

“…The degree of retropulsion varies depending on the severity of stone impaction and the location of the stone in the ureter . Retrograde migration results in increased operating time . Previous AUA guidelines reported an average of 1.33 procedures per patient for ureteroscopy of ureteric stones .…”
