|---|---|
| renal impression | A hollow on the visceral surface of the right lobe of the liver, in which lies the right kidney. Synonym: impressio renalis. (05 Mar 2000) |
| renal infantilism | renal rickets |
| renal insufficiency | Defective function of the kidneys, with accumulation of waste products (particularly nitrogenous) in the blood. (05 Mar 2000) |
| renal labyrinth | Proximal and distal convoluted tubules and the associated renal corpuscles supplied by branches of the interlobular arteries. Synonym: labyrinthus, pars convoluta lobuli corticalis renis, labyrinth, Ludwig's labyrinth, renal labyrinth. (05 Mar 2000) |
| renal lobe | One of the subdivisions of the kidney, consisting of a renal pyramid and the cortical tissue associated with it. Synonym: lobus renalis. (05 Mar 2000) |
| renal masses in children | <radiology> Hydronephrosis, obstructed duplication, multicystic dysplastic kidney, 2nd most frequent abdominal mass in the neonate, ureteropelvic atresia during metanephric intrauterine phase, 40% contralateral involvement, mesoblastic nephroma, most common newborn solid renal tumour, Wilms tumour, multiloculated cystic nephroma, multiple noncommunicating cysts (12 Dec 1998) |
| renal medulla | The centre portion of the kidney. (27 Sep 1997) |
| renal nanism | Infantile renal osteodystrophy. (05 Mar 2000) |
| renal osteitis fibrosa | renal rickets |
| renal osteodystrophy | Generalised changes in the bone which resemble osteomalacia and rickets, occurring in those with chronic renal failure. (27 Sep 1997) |
| renal papilla | <anatomy> The apex of a renal pyramid that projects into a minor calyx; some 10 to 25 openings of papillary ducts occur on its tip, forming the area cribrosa. Synonym: papilla renalis. (07 Mar 2000) |
