Magnesium transport in the nephron

American Journal of Physiology-Renal Physiology, 1980
Magnesium is filtered at the glomerulus to the extent of 70-80%, of which about 80-95% is reabsorbed by the various nephron segments. Recent evidence from micropuncture and microperfusion experiments has characterized the tubular handling of magnesium. The proximal convoluted tubule reclaims 20-30% of the filtered magnesium, considerably less than the

Conserving Nephrons in Cholesteatoma

Journal of Urology, 1980
A case of cholesteatoma, clearly delineated by preoperative air contrast retrograde pyelography, was treated like stone disease by removal of the obstructing material from the renal pelvis and pelvic ureter. A 7-year followup suggests that conservative surgical management may be the preferred treatment, since there is no evidence to date that ...

Urate transport in the nephron

American Journal of Physiology-Renal Physiology, 1979
This paper summarizes the literature on the sties of urate transport, secretory and reabosrptive, in the nephron. In the animals studied thus far the bulk of urate transport occurs in the proximal tubules. Two patterns of transport have been uncovered. In one, urate is secreted and reabsorbed throughout the convoluted tubule (perhaps the pars recta as

Calcium transport in the nephron

American Journal of Physiology-Renal Physiology, 1979
Ionized and complexed calcium are filtered at the glomerulus and more than 95% of the filtered load is reabsorbed along the length of the nephron. In the proximal convoluted tubule calcium is absorbed in proportion to sodium and water, suggesting a passive mechanism.

Distal nephron neoplasms

Seminars in Diagnostic Pathology, 2015
Tumours of the distal nephron are uncommon but can create diagnostic difficulties. They may be divided into three groups-tumours of intercalated cell phenotype, those of principal cell phenotype and others with an unconfirmed distal nephron origin. Oncocytomas, chromophobe carcinoma and hybrid oncocytoma chromophobe carcinoma, all show features of ...

Principles of nephron differentiation

American Journal of Physiology-Renal Physiology, 1978
Differentiation of cell function should be studied in homogeneous cell populations. The differentiating mammalian kidney is a thoroughly heterogeneous organ. Consequently, the single epithelial segment was studied in situ and, particularly, by in vitro analysis of physical, chemical, and ultrastructural phenomena in perfused and nonperfused dissected ...

[Nephron sparing surgery].

Minerva urologica e nefrologica = The Italian journal of urology and nephrology, 2004
The role of nephron sparing surgery in patients with a solitary kidney, bilateral kidney tumors or an impaired renal function has been widely accepted. Partial nephrectomy in patients with a normal contralateral kidney is still under discussion.We evaluated the effectiveness and safety of the nephronsparing surgery in the treatment of low stage renal ...
