“…It is also noteworthy that in horses, kidney disease is typically associated with digestive and respiratory problems and may also be related to the nephrotoxicity of some medications administered at length (BAYLY; PARADIS; REED, 1980;DIVERS et al, 1987;1992;CUNILLERAS;HINCHCLIFF, 1999;BAYLY, 2000). Tabet et al (2005) reported that renal biopsy is a technique used to identify the injury, evolution and severity of renal diseases but may cause complications, such as subcapsular and retroperitoneal hematomas, renal lacerations and bleeding in the renal arteries and veins.…”

In equines, kidney diseases are typically associated with respiratory and digestive problems, but surgical intervention is not common. The study of kidney blood vessels of domestic and wild animals are of fundamental importance for understanding many aspects of their physiology and nutrition. The current study used 30 pairs of kidneys from English Thoroughbred horses being 15 males and 15 females of different ages. The organs were donated by the Jockey Club of Sao Paulo. During the animal necropsies, the kidneys and their arteries and veins were removed together. The organs were fixed in formalin 10% for about 48 hours, for dissection and individualization of the components of the renal pedicle. After dissecting the material, the components of the renal pedicle were individualised. To analyse the results, the cranioventral, craniodorsal, caudoventral and caudodorsal quadrants were defined using two lines: craniocaudal and dorsoventral. Overall, the following results were obtained: in the hilar region, two arterial branches occurred in the right kidney in 50% of cases and two in the left kidney (33.3%); in the juxtahilar region, the number of arterial branches ranged from four to five in the right kidney in 20% of cases, whereas six occurred in the left kidney (16.7%); and regarding the extrahilar region, three branches occurred in the right kidney (26.7%) and three in the left kidney (20.0%).Keywords: Equine.

ResumoAs doenças renais em equinos, geralmente estão associadas a problemas respiratórios e digestórios, entretanto não são frequentes as intervenções cirúrgicas neste órgão para estes animais. O estudo dos vasos sanguíneos relativos aos rins nos animais domésticos e selvagens é de fundamental importância para o entendimento de diversos aspectos de sua fisiologia e nutrição. Neste trabalho, foram utilizados 30 pares de rins de equinos Puro Sangue Inglês, dos quais 15 machos e 15 fêmeas, de diferentes faixas etárias, provenientes de doação do Jockey Club de São Paulo. Durante a necropsia dos animais, os rins unidos por meio de suas artérias e veias renais foram retirados em bloco. Em seguida, foram fixados em solução de formol a 10%, por aproximadamente 48h, para a dissecação e individualização dos componentes dos pedículos renais. Para a análise dos resultados foram demarcados os quadrantes cranioventral, craniodorsal, caudoventral e caudodorsal, com duas linhas uma craniocaudal e a outra dorsoventral. Os resultados obtidos revelaram que: os ramos arteriais da região hilar são observados no rim direito em número de dois em 50%, no esquerdo em número de dois (33,3%), os ramos arteriais na região justahilar são computados no rim direito em número de quatro a cinco em 20% e no rim esquerdo em número de seis (16,7%), e nos ramos dispostos na região extrahilar são registrados no rim direito em número de três (26,7%) e no esquerdo em número de três (20%).

“…Wichtige Parameter zur Einschätzung der funktionellen Integrität des proximalen Tubulus sind die Größen der fraktionellen Clearance der einzelnen Elektrolyte (Divers 1987) und das Verhältnis von Urin-Gammaglutamyltransferase (GGT) zu Urin-Kreatinin. Die mit dem Harn ausgeschiedene GGT stammt aus dem Bürstensaum des proximalen Tubulus.…”

“…Diese wird beim Pferd hauptsächlich durch Hypovolämie bei Kolik oder Diarrhoe hervorgerufen (Grossman et al 1982;Seanor et al 1984;Divers et al 1987) und ist oft reversibel. Jedoch kann eine lang anhaltende Hypoperlusion schließlich zu einem irreversiblen ischämischen intrinsischen (renalen) ANV führen.…”

“…Akute lokale Hypoperfusion und Hypoxie können auch durch Verlegung der Tubuli mit Myoglobinausfällungen bei Myopathien bzw. mit Zelldetritus bei Pyelonephritis verursacht werden (Divers et al 1987;Divers et al 1992). Weiterhin kann das renale ANV auch im Zusammenhang mit Intoxikationen entstehen.…”

ZusammenfassungDie Nierenfunktionsanalyse nach Btckhardt et al. (1996) Examination of renal function (Bickhardt et al. 1996) gives extensive information on renal disfunctions, This can be determined from a voided urine and a blood sample. Furthermore a transendoscopic, selective collection of urine from each ureter allows a differentiated assessment of the right and left kidney's function, Benal function of 38 patients of the clinic for horses were examined. Nine of them showed a deviation of the normal range. Fcur patients had acute renal diseases. ln h,vo cases there was a prerenal and in the other two an intrinsjc acute renal dysfunction. The horses were ln a severe bad general condition, Serum urea and creatinine levels were elevated, In two horses a serum electrollte disturbance could be seen. In examination of renal function a reduction of renal creatinine clearance was obvious. In three cases an enormous elevation of tubular enzyme excretion (U 7GT/Crea) was found, Five of nine horses showed chronic nephropathies. Poor performance and weariness were the most dominating clinical findings. The horses showed elevated serum urea and creatinine levels and in two cases a hyperkaliaemia occurred. In examination of renal function a reduction of renal creatinine clearance and in one case an elevation of fraclional lactate excretion could be found.
