paraneoplastic syndrome Oncology A co-morbid condition due to the indirect–remote or 'biologic' effects of malignancy, which may be the first sign of a neoplasm or its recurrence; PSs occur in > 15% of CAs, are caused by hormones, growth factors, biological response modifiers, and other as-yet unidentified factors, and may regress with treatment of the primary tumor. See Ectopic hormone.

pertaining to the kidney. See also kidney
results from infected emboli and infarcts. Usually without localizing signs unless they are very large and palpable, or when they extend into the renal pelvis and cause pyelonephritis.
rare, incidental necropsy finding.
failure of the renal tissue to develop; unilateral agenesis causes compensatory hypertrophy in the single kidney; bilateral is fatal. Commonly accompanies genital tract malformation.
avian renal hemorrhage
sporadic unexplained disease of turkeys; sudden death is common.
is conducted usually with a biopsy needle introduced percutaneously through the flank. In food animals it is possible to fix the left kidney via a rectal manipulation, but the right kidney can be impossible to reach.
renal capsular cyst
see feline perirenal cysts.
commonest in old male dogs. They are very large, spread locally and metastasize widely.
renal clearance tests
laboratory tests that determine the ability of the kidney to remove certain substances from the blood. See also phenolsulfonphthalein
clearance test, inulin
renal cortical fissures
external fissures created by the lobar structure of the large ruminant kidney.
renal cortical hypoplasia
see renal dysplasia (below).
renal cortical necrosis
results from patchy or complete renal ischemia and is part of the terminal state of many diseases, e.g. severe metritis, grain overload in cattle, azoturia in horses.
renal countercurrent system renal cyst
incidental necropsy finding except for polycystic kidney
disease. See also feline perirenal cysts
inherited as an autosomal dominant trait in middle-aged German shepherd bitches with generalized nodular dermatofibrosis.
the application of the principles of dialysis for treatment of renal failure (below). See also hemodialysis
diverticuli of the renal pelvis.
reduced capacity to excrete metabolic products which accumulate systemically and are detectable clinicopathologically by renal function tests. The early stage of uremia.
small, misshapen kidneys at birth. May be caused by intrauterine infection of the fetus by virus, but numerous inherited renal dysplasias occur in dogs. They occur in several breeds and are manifested by signs of chronic renal insufficiency, e.g. polyuria, polydypsia, poor growth and weight gain, pale mucous membranes, and renal secondary osteodystrophia fibrosa, from an early age.
renal erythropoietic factor
inability of the kidney to maintain normal function. Impairment of kidney function affects most of the body's systems because of its important role in maintaining fluid balance, regulating the electrochemical composition of body fluids, providing constant protection against acid-base imbalance, and controlling blood pressure. See also kidney
renal function tests
include blood urea nitrogen and serum creatinine estimations, tests of concentrating ability, tests of ability to excrete test substances, e.g. phenolsulfonphthalein (PSP) clearance test. Of the urine tests, only specific gravity (SG) has any significance in terms of a function test but abnormalities of urine should lead to a function test being conducted.
a fissure on the medial border of the kidney through which arteries, veins and ureter enter.
renal hypophosphatemic rickets
inherited as an X-linked dominant trait in children and mice; characterized by hypophosphatemia and normocalcemia due to failure of phosphate resorption in renal tubules, and skeletal deformities. Called also vitamin-resistant rickets.
results from embolic or thrombotic occlusion of renal arteries or branches. Clinical signs are those of renal colic initially followed by toxemia if the infarct is infected.
see renal dysfunction (above).
a significant cause of renal dysfunction and cortical and medullary necrosis. Is usually part of a general state of shock, dehydration and severe toxemia.
a large mass of a kidney, comprising the tissue contributing to each pyramid; kidneys may be unilobar (unipyramidal), e.g. cats, dogs, small ruminants, horses, or multilobar (multipyramidal), e.g. cattle, pigs.
small masses of kidney tissue comprising a medullary ray and its associated nephrons.
renal medullary necrosis
necrosis of the renal medulla due to restriction of blood flow in medullary vessels, usually due to venous occlusion.
renal osteodystrophy, renal osteitis fibrosa, renal osteitis fibrosa cystica renal oxalosis
deposition of oxalate crystals in renal tubules of patients poisoned by dietary oxalate, usually in poisonous plants.
renal papillary necrosis
necrosis of renal papillae due usually to obstruction to urinary flow or poisoning or dehydration.
the chamber in the kidney into which the collecting tubules discharge urine and from which urine is voided into the ureter.
renal plasma flow
the effective rate of blood flow through the kidneys; the determining factor relative to the rate of glomerular filtration.
renal portal system
a system unique to birds; half to two thirds of the blood supply to the kidney comes from the hindlimbs via veins and terminates in peritubular capillaries where it is mixed with arteriolar blood coming from the glomeruli.
cessation of the excretory function of the kidney; oliguria.
renal spongiform encephalopathy
spongiform encephalopathy associated with renal failure.
renal vein thrombosis
commonly associated with renal amyloidosis in dogs.
Patient discussion about renal
Q. what cause pain around kidney uncomfortable pressure swelling right side back
A. thanx....the pain is dull and there's no fever: muscular pain perhaps? If it worsens, persists or fever developes; I will head to the Doctor. thamx again....
Q. experiencing sharp pain in my right kidney region... pain is acute and doesnt radiate... recently PE left lung have been taking warfrin, panadiene forte, two kinds of cholesterol/triglycerine reducing meds and champix quit smoking medication... recently tests showed the hight cholesterol and triglys' levels and also a swollen liver... pain is not in my liver area... past pain in this kidney recurrent but never as bad. always dull.. many years ago had a uti, which caused high protiene levels.. very bad at finishing anti-biotics... recently had tonsilitis.. This hurts and is tender to touch but does not bring on sharp pain when touched, sharp pain comes and goes after taking pain relief
A. Go to see a doctor - although its tempting to make the diagnosis over the net (I have several ideas about what it might be), it sounds like serious, especially if you had a PE lately - it could be a thrombus in the vein of the kidney, or maybe a stone (sounds like that according to the description of the pain). However, as I said, making the diagnosis without even seeing you isn't the wisest thing to do.More discussions about renal
