“…First described in the 19th century, phleboliths generally present as layers of calcified fibrous tissue covered by a layer of endothelium which is continuous with the intimal layer of vein wall [ 19 ]. Differentiating characteristics include a central lucency, comet tail sign, and anatomical distribution [ 20 ]. Although advances in radiology have improved the landscape of differentiating phleboliths from ureteral calculi, they still present a diagnostic challenge particularly in the emergency setting, leading to unnecessary intervention and associated financial and resource burdens.…”

Radiomics is increasingly applied to the diagnosis, management, and outcome prediction of various urological conditions. Urolithiasis is a common benign condition with a high incidence and recurrence rate. The purpose of this scoping review is to evaluate the current evidence of the application of radiomics in urolithiasis, especially its utility in diagnostics and therapeutics. An electronic literature search on radiomics in the setting of urolithiasis was conducted on PubMed, EMBASE, and Scopus from inception to 21 March 2022. A total of 7 studies were included. Radiomics has been successfully applied in the field of urolithiasis to differentiate phleboliths from calculi and classify stone types and composition pre-operatively. More importantly, it has also been utilized to predict outcomes and complications after endourological procedures. Although radiomics in urolithiasis is still in its infancy, it has the potential for large-scale implementation. Its greatest potential lies in the correlation with conventional established diagnostic and therapeutic factors.

“…Calcification due to tubal tuberculosis usually takes the form of small linear streaks that can be straight, bent, or curved, and ovarian abscesses or granuloma may also be present ( 31 ). The “comet sign” is often seen in pelvic phleboliths; the head is phlebolith and the irregular tapering soft tissue attached to it is the comet tail ( 32 ). Pelvic phleboliths need to be differentiated from ureteral calculi.…”

“…Pelvic phleboliths need to be differentiated from ureteral calculi. High-density calculi are surrounded by ring-thickened soft tissue, namely the “rim sign” ( 32 ). Adnexal tumors with calcification that need to be identified include serous epithelioma, ovarian fibrothecoma, teratoma, and Brenner tumor.…”

Purpose of the Review This review article aims to show the actual role of Imaging, especially DECT (Dual Energy CT), in recognition of renal calculi. Recent Findings CT and in particular DECT have some implications in renal stone disease; CT is considered the gold-standard in the diagnosis in case of acute flank pain caused by nephrolithiasis, better than ultrasound, that represent the first approach, in some specific cases. DECT instead in these days, has increase a very particular role. Summary About 12% of the world’s population will experience urinary stones, and 50% of affected people experience a recurrence within 10 years after their first diagnosis. There are many different types of calculi, that could form and stay or could form and then goes to localize in different anatomical site in the urinary system: kidney, ureters, bladder, and urethra. Calculi, especially with high dimensions, cause the typical flank pain, also known as renal colic. The precise cause of their formation is still unknown, it is frequently believed that mineral deposition on a nidus of the mucoprotein matrix is what causes them to form. The preferred Imaging method for detecting urinary stones is ultrasonography (used like the first approach), and Computed Tomography (gold standard), more rapid if “low-dose CT”. In these days, Dual Energy Computed Tomography is useful to determine the composition of the calculation. In fact, it is more effective than single-energy CT; it creates a better separation of stones from iodine; and it allows better measures of stone composition with better differentiation of urate stones from others (even at low doses).
