| renal tubular acidosis | <nephrology> A rare sometimes familial disorder of the renal tubule characterised by the inability to excrete urine of normal acidity. This leads to a hyperchloraemic acidosis which is often associated with one or more secondary complications such as hypercalcinuria with nephrolithiasis and nephrocalcinosis, rickets, or osteomalacia and severe potassium depletion. (25 Jun 1999) |

| renal tubular transport, inborn errors | Genetically determined disorders of the reabsorptive functions of the kidney with regard to specific nephron segments responsible for specific transport functions, classifiable by proximal nephron function, loop of henle function, and distal nephron function. The transport defects can be selective or nonselective. (12 Dec 1998) |
| Pick's tubular adenoma | A neoplasm of the ovary, arising from the ovarian stroma, mimicking to a greater or lesser extent derivatives of the sex cord mesenchyme of the testis, and sometimes causing defeminization and virilization. (12 Dec 1998) |
| primary renal tubular acidosis | A metabolic defect in the mechanism of urinary acidification that may be either the transient type, with onset in infancy, or the persistent type, with onset in childhood or adult years; both types are familial. (05 Mar 2000) |
| secondary renal tubular acidosis | Renal tubular acidosis that may occur as a complication of hypercalcaemic states, hyperglobulinaemic disorders, and in some other chronic renal conditions; a regular component of De Toni-Fanconi syndrome. (05 Mar 2000) |
| osteopetrosis with renal tubular acidosis | <syndrome> An inherited deficiency of carbonic anhydrase II that results in osteopetrosis and metabolic acidosis. Synonym: osteopetrosis with renal tubular acidosis. (05 Mar 2000) |
| ovarian tubular adenoma | <oncology, tumour> A type of ovarian tumour whose sells secrete a male sex hormone (testosterone) causing virilisation in women. (27 Sep 1997) |
| testicular tubular adenoma | A neoplasm of the ovary, arising from the ovarian stroma, mimicking to a greater or lesser extent derivatives of the sex cord mesenchyme of the testis, and sometimes causing defeminization and virilization. (12 Dec 1998) |
| tubular | <anatomy> Shaped like a tube, of or pertaining to a tubule. Origin: L. Tubularis (18 Nov 1997) |
| tubular adenoma | <tumour> A benign neoplasm composed of epithelial tissue resembling a tubular gland. (05 Mar 2000) |
| tubular aneurysm | The uniform dilation of an artery along a considerable distance. Synonym: cylindroid aneurysm. (05 Mar 2000) |
| tubular carcinoma | <tumour> A well-differentiated form of ductal breast carcinoma with invasion of the stroma by small epithelial tubules. (05 Mar 2000) |
| tubular cyst | A cyst formed by the dilation of any occluded canal or tube. Synonym: tubular cyst. (05 Mar 2000) |
| tubular excretory mass | The mass of functioning excretory tubules of the kidney determined from the excretion of iodopyracet, or other compounds processed in the kidney primarily by tubular secretion, when large doses are used. (05 Mar 2000) |
| tubular forceps | A long slender forceps intended for use through a cannula or other tubular instrument. (05 Mar 2000) |
