Kidney stones are collections of microcrystals formed inside the kidneys, which affect 6% to 12% of the population worldwide, with an increasing recurrence (50%-72%) after the first episode. The most abundant type is calcium oxalate (66%), described as monohydrated (COM) and dihydrated (COD). An issue in their chemistry is the transformation process of the metastable specie (COD) into the stable one, which is chemically, and in appearance, monohydrated.

Imaging techniques play a critical role in the initial diagnosis, follow-up and urological management of urinary tract stone disease. The are many useful tools for diagnosing urolithiasis, including conventional plain radiography, intravenous urography, ultrasonography, computed tomography and magnetic resonance imaging.

- - A study was conducted to investigate if kidney stones (nephrolithiasis) cause changes in the density of renal papillae, comparing a stone-forming group (SFG) with a healthy control group (CG).
- - The results indicated that the papillae density in the SFG was significantly higher (43.9 HU) compared to the CG (33.9 HU), while no notable difference was found between the affected and unaffected sides in the SFG.
- - The findings support the theory of calcium deposits in the renal papillae, with a high accuracy rate in distinguishing between the two groups based on papillae density measurements (area under the curve of 0.91).
Objectives: To determine if calcium deposits in the papillae can be identified by unenhanced computed tomography (uCT) even before renal stones develop.
Methods: A retrospective review of 413 patients with calculi identified 31 patients (stone-forming group) with a history of urinary tract calculi with a calculus demonstrated by uCT and a stone-free uCT before calculi had developed. The control group (n = 31) was composed of live kidney donors with no history of calculi and a stone-free uCT.
