“…The urine-specific gravity varies with body hydration, fluid intake, and serum osmolarity. In agreement with the results of this study, the presence of proteinuria and marked glycosuria, urinary density can be increased, leading to the interpretation that the renal tubules have a greater capacity for urine concentration in the presence of those molecules [14]. The chemical analysis of the animals' urine showed a significant difference in qualitative proteinuria after intervention between groups (Table 3).…”

“…Essas são células epiteliais que revestem a mucosa da pelve renal, ureter, bexiga e uretra. Existem também células epiteliais escamosas associadas à próstata, vagina e útero, que geralmente não têm importância diagnóstica (REINE; LANGSTON, 2005).…”

“…Os cilindros são classificados com base no componente predominante (REINE; LANGSTON, 2005). Cilindros hialinos são precipitados proteináceos puros de mucoproteína que geralmente têm significância patológica mínima e podem ter breve formação em situações como febre, exercícios e congestão renal passiva.…”

Testes de avaliação de injúria renal precoce em cães e gatos

ResumoA identificação de injúrias renais é uma medida importante que tem como objetivo evitar a instalação de alterações irreversíveis, tal como a doença renal crônica, problema de incidência elevada em cães e gatos. As concentrações séricas de ureia e de creatinina são os parâmetros rotineiramente avaliados, quando se busca a identificação de insuficiência renal. Porém, estes valores só se encontram alterados quando 66 a 75% dos néfrons apresentam incapacidade de função excretora. Em muitas situações, uma agressão desta magnitude pode ser suficiente para causar a morte do animal. Avaliações que identifiquem a agressão, antes mesmo que as funções encontrem-se alteradas vêm sendo estudadas, mostrando serem importantes avaliadores precoces de possíveis danos irreversíveis. A quantificação das enzimas urinárias, proteína urinária, fração de excreção de eletrólitos, taxa de filtração glomerular e a observação do sedimento urinário têm grande valor como exames sensíveis de injúria renal precoce. Há a necessidade do emprego de testes que auxiliem, não somente na identificação precoce, mas também na determinação da progressão da doença e da eficácia do tratamento. A presente revisão objetiva descrever os testes laboratoriais que podem ser realizados para a avaliação precoce de injúria renal de cães e gatos. Palavras-chave: Injúria renal, diagnóstico precoce, taxa de filtração glomerular, proteinúria AbstractThe identification of kidney injury is an important measure that aims to prevent the installation of irreversible changes, such as chronic kidney disease, seen most frequently in dogs and cats. Serum urea and creatinine parameters are routinely assessed, when searching renal failure. However, these values are only changed when 66 to 75% of glomerular filtration rate has been lost. In many situations, an attack of this magnitude may be enough to cause the animal's death. Evaluations that identify the aggression, even before the functions themselves are altered, have been studied and shown to be important early evaluators, signaling prior to possible irreversible damage. The quantification of urinary enzymes, urinary protein, fractional excretion of electrolytes, glomerular filtration rate and urinary sediment, have shown great value as sensitive tests of renal injury. There is the need of the use of tests that assists in early diagnosis and also determines the progression of disease and efficacy of the treatment. The present review aims to describe the laboratory tests that may be performed to evaluate early kidney injury in dogs and cats.

“…A complete urine analysis includes physical examination, chemical tests, sediment examination and enzyme estimation (1). Urinalysis is considered as a main indicator in the estimation of the kidneys physiology, and liver function based on bilirubin measurement, metabolic disorder such as diabetes mellitus by detecting of urine glucose level and ketone bodies, and intravascular hemolysis as indicated by increased hemoglobin urine (2).…”

SummaryThe study was designed to determine the abnormal urine components such as red blood corpuscles, protein, bilirubin, nitrites, specific gravity, glucose, hydrogen ion, ketones, urobilinogen and leukocyte abnormality in k9 dogs urine.The present study was carried out on 135 asymptomatic dogs (65 males and 70 females) with age (2 -8 years) in Al-Najaf governorate between February 2016 and April 2016. At morning, urine specimens were collected from dogs and tested via method of dipstick. Mass urinary screening is a suitable tool to detect dogs with asymptomatic progressive renal diseases, however the urinalysis can deliver to us information not merely about the kidneys and bladder, but also the liver, pancreas, and other organs, as well as, helping to make a diagnosis, in addition to determining a prognosis (a prediction of the consequence of the disease) and response to treatment. Results showed that 46 (34%) dogs were with urinary abnormalities, hematuria was the most frequent abnormality showed 28(60.9%), nitrituria 10(21.7%), proteinuria 4(8.7%), bilirubinuria in 2(4.3%) and decreased specific gravity 2(4.3%) respectively, pH (0%), glucose (0%), ketones (0%), urobilinogen (0%) and leukocyte (0%).
