Kidney stone analysis: "Give me your stone, I will tell you who you are!".

Cloutier J, Villa L, Traxer O, Daudon M - World J Urol (2014)

Bottom Line: Stone analysis is an important part in the evaluation of patients having stone disease.Unfortunately, chemical methods often are inadequate to analyze accurately urinary calculi and could fail to detect some elements into the stone.Here, specific chemical types with their different crystalline phases are shown in connection with their different etiologies involved.

ABSTRACT

Introduction: Stone analysis is an important part in the evaluation of patients having stone disease. This could orientate the physician toward particular etiologies.

Material and methods: Chemical and physical methods are both used for analysis. Unfortunately, chemical methods often are inadequate to analyze accurately urinary calculi and could fail to detect some elements into the stone. Physical methods, in counterpart, are becoming more and more used in high-volume laboratories. The present manuscript will provide a review on analytic methods, and review all the information that should be included into an appropriate morpho-constitutional analysis.

Conclusion: This report can supply an excellent summarization of the stone morphology and give the opportunity to find specific metabolic disorders and different lithogenic process into the same stone. Here, specific chemical types with their different crystalline phases are shown in connection with their different etiologies involved.

COD stones subtype IIa. Top stone made of small octahedral crystals of weddellite as commonly observed in patients who form stones because hypercalciuria. Bottom stone made of both small and very large crystals (arrows) of weddellite as commonly found in patients who suffered hypercalciuria, hyperoxaluria and, often mild hypocitraturia

Fig13: COD stones subtype IIa. Top stone made of small octahedral crystals of weddellite as commonly observed in patients who form stones because hypercalciuria. Bottom stone made of both small and very large crystals (arrows) of weddellite as commonly found in patients who suffered hypercalciuria, hyperoxaluria and, often mild hypocitraturia

Mentions: Weddellite stones correspond to type II of the classification. Subtypes IIa to IIc are often related to hypercalciuria either associated or not with other conditions favoring stones growth. For example, we found that IIa or IIb subtypes made of large COD crystals were frequently related to hypercalciuria associated with hyperoxaluria and relative hypocitraturia (Fig. 13).Fig. 13
