“…All urine samples were analyzed by capillary electrophoresis as a reference method in Bioanalytical Laboratory CSU "Analytical Spectrometry" (St. Petersburg, Russia) according to the procedure described in [4]. Capillary electrophoresis system "Capel 105 M" (Lumex, Russia) with spectrophotometric detector with a wavelength range 190-400 nm was used for analysis of inorganic cations (calcium, magnesium, sodium, potassium, ammonium) and anions (chloride, sulfate, phosphate) in urine samples diluted in 400-800 times.…”

“…Capillary electrophoresis (CE) is considered to be one of the most accurate analytical techniques for urine analysis, offering a number of simple techniques for quantification of inorganic and organic cations and anions in urine. Direct and indirect UVdetection is used most often in CE [4][5][6][7][8][9][10]. Spectrophotometric techniques are applied for calcium, magnesium, phosphate, uric acid and creatinine quantification.…”

h i g h l i g h t s g r a p h i c a l a b s t r a c tDescription of two homemade platforms for the cheap quantification of creatinine level in urine. Image processing to extract absorption spectra and spectral fingerprints. PLS regression for creatinine evaluation in urine from digital camera images.Validation of results with capillary electrophoresis reference data.a r t i c l e i n f o . Good repeatability was observed for intra-day (1.7e2.9%) and inter-day (3.6e6.5%) measurements evaluated on three consecutive days. The performance of CDS and CSPT was also validated in real human urine samples (n ¼ 26) using capillary electrophoresis data as reference. Corresponding Partial Least-Squares (PLS) regression models provided for mean relative errors below 10% in creatinine quantification.

“…A iniciação da formação dos cálculos urinários envolve a excreção aumentada de solutos, a supersaturação urinária e precipitação de cristais, a presença de matriz orgânica, que pode organizar ou modificar o crescimento dos cristais, e a ação de moléculas que inibem ou promovem a formação e deposição de cristais (FINLAYSON, 1978). A excessiva concentração de promotores de cálculos urinários, como oxalato, urato, cálcio, fosfato, amônia e a concentração insuficiente de inibidores, como citrato, pirofosfato e magnésio, são importantes alterações e podem levar ao desenvolvimento de urólitos (SIDOROVA & GRIGORIEV, 2012).…”

RESUMOA urolitíase é comum na clínica de cães e os casos de recidivas são frequentes. Decorre do desenvolvimento de urólitos no trato urinário e pode levar a alterações graves, como obstruções do fluxo urinário. Diversos fatores, sejam hereditários, congênitos ou adquiridos, podem estar envolvidos no desenvolvimento dos cálculos urinários. Os urólitos que mais frequentemente acometem animais da espécie canina são aqueles formados de estruvita, oxalato de cálcio, urato, cistina, fosfato de cálcio, xantina e sílica. No entanto, cálculos urinários com outras composições como de 2,8-diidroxiadenina podem acometer menos frequentemente animais dessa espécie. O conhecimento dos mecanismos que ocasionam a formação e o desenvolvimento dos diferentes tipos de urólito permite a instauração de protocolos de tratamento específicos mais eficientes e que reduzam a possibilidade de ocorrência de recidivas. PALAVRAS-CHAVE: cálculo urinário, canino, patogenia ETIOPATHOGENESIS OF UROLITHIASIS IN DOGS ABSTRACTUrolithiasis are common in dogs and recurrences are frequent. This disease results from the development of uroliths in the urinary tract and may lead to important conditions, such as urinary flow obstructions. Many factors, hereditary, congenital or acquired may be involved in the development of urinary calculi. In dogs, the most common urolith compositions are struvite, calcium oxalate, urate, cystine, calcium phosphate, xanthine and silica. However, urinary calculi with different compositions, such as 2,8-dihydroxyadenine may less frequently affect these animals. Knowledge of the mechanisms involved in the formation and growth of each urolith type allow the establishment of specific treatment protocols that are more efficient and reduce the possibility of recurrences.
