Collecting Duct Carcinoma: A Rare Entity [PDF]
Collecting duct carcinoma is a rare and highly aggressive subtype of renal cell carcinoma. The incidence rate is less than 1-2% of all renal tumors and usually, affect middle-aged adult, commonly in men.

Altered collecting duct adenylyl cyclase content in collecting duct endothelin-1 knockout mice [PDF]
Background Endothelin-1 (ET-1) inhibition of vasopressin (AVP)-stimulated water reabsorption by the inner medullary collecting duct (IMCD) is associated with reduced cAMP accumulation.

Collecting duct carcinoma: A rare renal tumor [PDF]
The most common primary malignant renal tumor is renal cell carcinoma (RCC), which accounts for 3% of all adult malignancies. Bellini duct carcinoma or collecting duct carcinoma is an unusual rare variant of RCC.

Collecting duct carcinoma associated with oncocytoma [PDF]
Collecting duct carcinoma (CDC) is a rare, highly aggressive malignant neoplasm that arises from the collecting duct epithelium of the kidney. CDC was reported to coexist with renal cell and transitional cell carcinomas.

Renal Collecting Duct Carcinoma and Concomitant Bladder Urothelial Carcinoma: A Case Report [PDF]
The simultaneous occurrence of renal collecting duct (Bellini duct) carcinoma and bladder urothelial carcinoma is very rare. A 68-year-old female patient with bladder urothelial carcinoma first received transurethral resection of the tumor.

The role of the collecting duct in urinary concentration [PDF]
In summary, the three major segments of the collecting duct subserve three different functions in the urinary concentrating mechanism. The main function of the cortical collecting tubule is to raise the fractional solute contribution and absolute concentration of urea in fluid that it delivers to the outer medullary collecting duct. The function of the

Water channels in the kidney collecting duct [PDF]
The ability to concentrate the urine was an essential step in the adaptation of animals to life in a terrestrial environment. Only mammals and birds produce a urine which is hypertonic to plasma. A concentrated urine is formed in the kidney collecting duct in response to vasopressin by the massive reabsorption of water from luminal fluid.

Biology of endothelin receptors in the collecting duct [PDF]
The collecting duct endothelin (ET) system, involving ET-1 and its two receptors, is involved in the physiologic regulation of renal sodium (Na), water, and acid excretion. Based on in vitro studies and experiments using genetically engineered rodents, the physiology of this system in the collecting duct is being elucidated. Activation of endothelin B (

Metabolic support of collecting duct transport [PDF]
The present studies address the metabolic processes that support the reabsorption of sodium and the secretion of bicarbonate in the interspersed but distinct principal and intercalated cells of the cortical collecting duct (CCD). In microperfused rabbit CCD, sodium reabsorption was measured by lumen-to-bath 22Na flux, and bicarbonate transport was ...

Collecting Duct Carcinoma and Endemic Nephropathy – Case Reports and Literature Review
Although collecting duct carcinoma is a subtype of renal cell carcinoma, several studies implicate association with urothelial carcinoma. The coexistence of collecting duct carcinoma and another renal neoplasm is rare.
