Bellini duct (collecting duct) carcinoma of the kidney
Urology, 1996Bellini duct (collecting duct) carcinoma of the kidney is a rare entity often misinterpreted as renal or transitional cell carcinoma on histologic examination. Immunohistochemical identification of specific antigens is needed for the differential diagnoses. We describe a case of Bellini duct carcinoma that arose from the collecting ducts of Bellini and

Collecting duct carcinoma is a rare form of renal tumour. Its recognition is important both clinically and histopathologically since it can mimic other renal neoplasms in appearance. Nephrectomy is the treatment of choice and, as the tumour usually pursues an aggressive course, adjuvant chemotherapy or immunotherapy may also be considered appropriate ...

Collecting duct carcinoma: cytogenetic characterization
Histopathology, 1992Most renal cell carcinomas are assigned to either the papillary or clear cell, non‐papillary type by morphological and cytogenetic criteria. In rare cases, papillary carcinomas of the kidney have been classified as collecting duct carcinoma because of their medullary localization and the associated hyperplastic and dysplastic epithelial lesions of ...

Morphology of rabbit collecting duct
American Journal of Anatomy, 1979AbstractRecently the assumed structural and functional homogeneity of the collecting duct (CD) has been questioned. The objective of this study was to determine if heterogeneity occurs in luminal surface membrane structure or in cytoplasmic configuration of cells in the collecting duct or both.

Cortically located collecting duct carcinoma
Urology, 2005Collecting duct carcinoma is a rare, highly aggressive, renal tumor arising from the distal collecting ducts. Various histologic patterns can be found in the same tumor but most demonstrate duct-like or papillary architecture surrounded by desmoplastic stroma.

The collecting duct is the terminal segment of the mammalian renal tubule, operating as the conduit for urine flow from several different nephrons to the renal calyces, and therefore is the final site for converting glomerular filtrate into urine. Two characteristics of the collecting duct are particularly germane to this major homeostatic function ...

Collecting duct renal cell carcinoma
Actas Urológicas Españolas (English Edition), 2011Bellini's renal cell collecting duct carcinoma is a rarely prevalent renal tumour, with low cancer-specific survival, although its rate of response to antiangiogenic therapies is unknown.We retrospectively revise a series of collecting duct tumours, with special emphasis on the indication of target therapies and on their results.Retrospective analysis ...

Adenosine Biosynthesis in the Collecting Duct
The Journal of Pharmacology and Experimental Therapeutics, 2003Adenosine regulates tubular transport in collecting ducts (CDs); however, the sources of adenosine that modulate ion transport in CDs are unknown. The extracellular cAMP-adenosine pathway refers to the conversion of cAMP to AMP by ectophosphodiesterase, followed by metabolism of AMP to adenosine by ecto-5'-nucleotidase, with all steps occurring in the ...

Collecting Duct Function and Sodium Balance
Annual Review of Medicine, 1982Our purpose is to review the role of the collecting tubule in sodium homeo stasis.2 Present understanding of collecting duct function is based primarily on work published in the last ten years. Because of its inaccessibility, little was known about the collecting tubule until the introduction of new investi gative techniques.

Kidney collecting duct acid-base “regulon”
Physiological Genomics, 2006Kidneys are essential for acid-base homeostasis, especially when organisms cope with changes in acid or base dietary intake. Because collecting ducts constitute the final site for regulating urine acid-base balance, we undertook to identify the gene network involved in acid-base transport and regulation in the mouse outer medullary collecting duct ...
