|---|---|
| segmental arteries of kidney | The branches of the renal artery that supply the anatomical segments of kidney. Usually five in number, they are end arteries and give off interlobar, arcuate and interlobular arteries in sequence. The latter send afferent arterioles to the glomeruli as well as branches to the kidney capsule. The segmental arteries of the kidney are identified as: anterior inferior (arteriae segmenti anterioris inferioris renis ); anterior superior (arteriae segmenti anterioris superioris renis ); inferior (arteriae segmenti inferioris renis ); posterior (arteriae segmenti posterioris renis ); and superior (arteriae segmenti superioris renis ). Synonym: arteriae renis, arteries of kidney. (05 Mar 2000) |
| pulpy kidney disease | An enterotoxaemia of sheep caused by the bacterium Clostridium perfringens type D and characterised by sudden death preceded in some cases by excitement, incoordination, and convulsions; also occurs in goats and rarely in cattle. (05 Mar 2000) |
| horseshoe kidney | <radiology> 50% most likely to be other GU anomaly, duplication, cryptorchidism, urethral anomaly, increased kidney tumours, Wilms -- in kids, adenocarcinoma -- later in life (12 Dec 1998) |
| putty kidney | A kidney containing caseous material trapped by stricture of the ureter due to tuberculous granulations in renal tuberculosis. Synonym: mortar kidney. (05 Mar 2000) |
| pyelonephritic kidney | <nephrology> A kidney deformed by multiple scars as a result of chronic or recurrent renal infection. (05 Mar 2000) |
| sigmoid kidney | Upper pole of one kidney fused with the lower pole of the other. (05 Mar 2000) |
| straight venules of kidney | Venules that drain the medullary pyramids of the kidney; they open into arcuate veins. Synonym: venulae rectae renis. (05 Mar 2000) |
| nonrotation of kidney | A developmental anomaly in which the hilum of the kidney retains its original position, facing ventrally. (05 Mar 2000) |
| superior pole of kidney | The superior end of the kidney. Synonym: extremitas superior renis. (05 Mar 2000) |
| superior segmental artery of kidney | Origin, anterior branch of renal. See: segmental arteries of kidney. Synonym: arteria segmenti superioris renis, artery of superior segment of kidney. (05 Mar 2000) |
| supernumerary kidney | A kidney, in addition to the two usually present, developed from the splitting of the nephrogenic blastema or from a separate metanephric blastema, into which a partial or complete reduplication of the ureteral stalk enters to form a separate, capsulated kidney; in some cases, the separation of the reduplicated organ is incomplete. (05 Mar 2000) |
| diabetic kidney disease | Kidney disease and resultant kidney function impairment due to the long standing effects of diabetes on the microvasculature (glomerulus) of the kidney. Features include increased urine protein and declining kidney function. Severe diabetic nephropathy can lead to kidney failure and end-stage renal disease. (27 Sep 1997) |
| disease, polycystic kidney | Genetic (inherited) disorders characterised by the development of innumerable cysts in the kidneys filled with fluid that replace much of the mass of the kidneys and reduce kidney function leading to kidney failure. (12 Dec 1998) |
| disk kidney | A disk-shaped organ produced by fusion of both poles of the contralateral kidney anlagen. Synonym: disk kidney. (05 Mar 2000) |
