tubular backleak

leakage of tubular fluid into the interstitium of the kidney is one of the factors in the pathogenesis of acute renal failure.

tubular maxima

the concentrations of solutes at which the renal tubules are working at full capacity and further increases in concentration will not increase the function. Called also T_m.

tubular necrosis

acute necrosis of the tubular epithelium caused usually by ischemia or exposure to a nephrotoxin; in most cases the patient succumbs to uremia in a few days. See also nephrosis.

tubular proteinuria

failure of the tubules to resorb small molecule proteins excreted by the glomerulus.

tubular reabsorption

reabsorption of solutes from the glomerular filtrate by the tubules, the conservation of protein, glucose and bicarbonate, and the conservation of the water that accompanies them.

tubular transport

refers to all processes which occur with renal tubular fluid during its transport from glomerular space to renal pelvis.

tubular transport maximum

when the tubular transport maximum for a renal tubular solute is exceeded the solute appears in the urine.
