Hypertension is a cause and consequence of chronic renal disease. Data from the United States Renal Data System USRDS identifies systemic hypertension as the second most common cause of end-stage renal disease, with diabetes mellitus being the first. Renal failure in patients with hypertension has many causes, including functional impairment secondary to vascular disease and hypertensive nephrosclerosis. Even in those in whom hypertension is not the primary process damaging the kidney,...

Screening for cancer. An active malignancy is an absolute contraindication to transplantation. Effective screening measures for patients at risk include chest radiograph, mammogram, PAP test, stool Hemoccult, digital rectal examination, and flexible sigmoidoscopy examination. Patients who have had a life-threatening malignancy but are potentially cured may be candidates for transplantation when there has been an appropriate disease-free interval. This interval generally is at least 2 years, and...

Hypertension and parenchymal disease of the kidney are closely interrelated. Most primary renal diseases eventually disturb sodium and volume control sufficiently to produce clinical hypertension. Both on theoretical and practical grounds, many authors argue that any sustained elevation of blood pressure depends ultimately on disturbed renal sodium excretion, ie, altered pressure natriuresis. Hence, some investigators argue that a clinical state of hypertension represents de facto evidence of...

A, The probability of end-stage renal disease in patients with proliferative lupus nephritis treated with different drug regimens. This update of the prospective trial by the National Institutes of Health NIH on the treatment of these patients clearly demonstrates that prednisone monotherapy, in a significantly greater proportion of patients, leads to the development of end-stage renal disease compared with patients on regimens containing cytotoxic drugs. The results between azathio-prine and...

A comparison of atherosclerotic renal artery disease and medial fibroplasia. The most common types of renal artery disease atherosclerotic renal artery disease ASO-RAD and medial fibroplasia are compared here. In general, ASO-RAD is observed in men and women older than 50 to 55 years of age, whereas medial fibroplasia is observed primarily in younger white women. Total occlusion of the renal artery and, hence, atrophy of the kidney beyond the stenosis are relatively common with ASO-RAD, but...

Autonomic neuropathy. Autonomic neuropathy accompanies advanced diabetic nephropathy. While an unvarying R-R interval may have minimal clinical importance, diabetic cystopathy and reduced bowel motility, including gastroparesis, may seriously impede quality of life. Questioning to discern the presence of travel-limiting diarrhea, obstipation, and gastroparesis should be included in each initial evaluation of a diabetic kidney patient.

Patient with hepatosplenic schistosomiasis, complicating intestinal mansoniasis. Note the shrunken liver and very large spleen, surface marked on the abdominal wall by black ink. Of these patients, 15 develop clinically overt glomerular lesions. Half of the 15 become hypertensive, most become nephrotic at some stage, and almost all progress to end-stage disease 54 .

The kidney possesses a remarkable capacity for restoring its structure and functional ability following an ischemic or toxic insult. It is unique as a solid organ in its ability to suffer an injury of such magnitude that the organ can fail for weeks and yet recover full function. Studying the natural regenerative process after an acute renal insult has provided new insights into the pathogenesis of acute renal failure ARF and possible new therapies. These therapies may limit the extent of...

Predominant distributions of renal vascular involvement. This diagram depicts the predominant distributions of renal vascular involvement by large, medium-sized, and small vessel vasculitides 2 . Note that all three categories may affect arteries, although arteries are least often affected by the small vessel vasculitides and often are not involved at all by this category of vasculitis. By the Chapel Hill definitions, glomerular involvement ie, glomerulonephritis is confined to the small vessel...

Urinalysis in acute renal failure ARF . A normal urinalysis suggests a prerenal or postrenal form of ARF however, many patients with ARF of postrenal causes have some cellular elements on urinalysis. Relatively uncommon causes of ARF that usually present with oligoanuria and a normal urinalysis are mannitol toxicity and large doses of dextran infusion. In these disorders, a hyperoncotic state occurs in which glomerular capillary oncotic pressure, combined with the intratubular hydrostatic...

Hemodialysis is a life-sustaining procedure for the treatment of patients with end-stage renal disease. In acute renal failure the procedure provides for rapid correction of fluid and electrolyte abnormalities that pose an immediate threat to the patient's well-being. In chronic renal failure, hemodialysis results in a dramatic reversal of uremic symptoms and helps improve the patient's functional status and increase patient survival. To achieve these goals the dialysis prescription must ensure...

Several inherited disorders have been described that result in isolated renal phosphate wasting. These disorders include X-linked hypo-phosphatemic rickets HYP , hereditary hypophosphatemic rickets with hypercalciuria HHRH , hypophosphatemic bone disease HBD , autosomal dominant hypophosphatemic rickets ADHR , autosomal recessive hypophosphatemic rickets ARHR , and X-linked recessive hypophosphatemic rickets XLRH . These inherited disorders share two common features persistent hypophosphatemia...

Potassium, the most abundant cation in the human body, regulates intracellular enzyme function and neuromuscular tissue excitability. Serum potassium is normally maintained within the narrow range of 3.5 to 5.5 mEq L. The intracellular-extracellular potassium ratio Kj Ke largely determines neuromuscular tissue excitability 1 . Because only a small portion of potassium is extracellular, neuromuscular tissue excitability is markedly affected by small changes in extracellular potassium. Thus, the...

Pathways for urea recycling. Urea plays an important role in the generation of medullary interstitial hypertonicity. A recycling mechanism operates to minimize urea loss. The urea that is reabsorbed into the inner medullary stripe from the terminal inner medullary collecting duct step 3 in Fig. 1-4 is carried out of this region by the ascending vasa recta, which deposits urea into the adjacent descending thin limbs of a short loop of Henle, thus recycling the urea to the inner medullary...
