Written by Ana María García Cano | Alejandro José Ravelo Marrero | Alba Arroyo Vega

ASPECTO ATÍPICO EN CÁLCULO URINARIO DE OXALATO CÁLCICO MONOHIDRATADO
Figure 1. Set of kidney stones of the same patient (a), examined individually according to their appearance (b, c and d). Typical calcium oxalate monohydrate kidney stone (e). Several kidney stones of 388.5 mg corresponding to the same patient (a). Depending on their appearance three kidney stones are distinguised: the first is brown, smooth, rounded surface and hard fracture consistency (b). The second is light brown, smooth, rounded surface and hard fracture consistency (c). The third is grayish, with a rough surface, and intermediate hardness (d).

Kidney stones belong to a 54-year-old patient with surgical history of multiple renal lithiasis, who presents an episode of left obstructive uropathy with infection due to a new event of lithiasis. She required a double J stent placement.

SIALOLITHIASIS: ANALYSIS AND CHEMICAL COMPOSITION

Written by María del Mar Rodríguez Rodríguez | Lucía Jiménez Mendiguchía | Ana María García Cano , Posted in Volumen 3

SIALOLITIASIS: ANÁLISIS Y COMPOSICIÓN QUÍMICA
In Figure 1 the sialolith of 93 mg obtained by maxillofacial surgery is shown. The macroscopic characteristics of this calculus were the following: honey colour, hard consistency and rough surface, typical features described in the literature. This sialolith corre sponds to a 46 years old patient, who presents an episode of right submandibular inflammation with suppuration by Wharton ́s duct caruncula. Sialoliths are most common within the body of the submandibular gland or Warton ́s duct (80 - 92%). From 6% to 20% of sialoliths occur in the parotid gland, and the remaining 1 - 2% are located within the sublingual or minor salivary glands.
