Chronic renal failure associated with hypercalcemia and hypophosphatemia was diagnosed in 6 horses. The renal lesions in 5 of the horses were classified as chronic glomerulonephritis and in the sixth, as chronic interstitial nephritis/pyelonephritis. There was no evidence of primary hyperparathyroidism or pseudohyperparathyroidism, thus suggesting that hypercalcemia associated with advanced renal failure in horses is related to a unique role of the equine kidney in calcium homeostasis.

The causes of the high incidence of vesicoureteral reflux in 161 patients with end stage renal disease was studied. In about half of these patients with pyelonephritis, reflux in combination with urinary tract infections is the cause of renal failure. Reflux is therefore found more often in this specific group. The incidence of reflux correlates with the duration of uremia. Reflux also is more common in patients with little or no diuresis. Theories of reflux into the "unused ureter" are discussed.

A 55-year-old woman in an advanced stage of chronic renal failure due to pyelonephritis developed severe hyponatraemia after receiving 400 mg/day of ibuprofen for 3 days. The typical symptoms and the hyponatraemia disappeared when the drug was withdrawn. The likely mechanism involved and the clinical implications are discussed.

Eight cases of acquired cystic disease of the kidney (ACDK) associated with chronic renal failure and hemodialysis are described. No patient had a family history or clinical evidence of congenital adult polycystic kidney disease (CAPKD). Glomerulonephritis was the cause of renal failure in 6, and pyelonephritis in 2. Massive renal and perirenal hemorrhage necessitated 3 nephrectomies in 2 patients. Single kidney weights did not exceed 280 Gm., a major feature in the distinction of ACDK from CAPKD. Morphologically, in addition to the usual stigmata of end-stage kidneys, 40 to 80 per cent of the renal parenchyma was replaced by small cysts. Continuity of cysts with tubules was established by nephron dissection.

Gross vesico-ureteric reflux is the essential pathogenetic factor in the etiology of the small, scarred kidney of non-obstructive, chronic pyelonephritis (reflux nephropathy). 18 (12.5%) of 144 patients entering a dialysis-transplant programme had end-stage reflux nephropathy. The majority of patients initially presented with severely impaired renal function, hypertension and significant proteinuria. Documented urinary tract infections had only occurred in one-third of the patients. 8 of the 12 women presented during a pregnancy, usually with a presentation resembling toxaemia of pregnancy. Reflux nephropathy is a significant cause of end-stage chronic renal failure.

A 68-year-old female on two-year chronic hemodialysis for chronic renal failure due to chronic pyelonephritis, was admitted to hospital for weakness, dulled sensorium and dizziness. On examination the patient was in a state of circulatory collapse, the electrocardiogram showed an accelerated idioventricular rhythm and laboratory analysis revealed extreme hyperkalemia (K+ 10.1 mmol/l). There were no common causes of shock, such as hypovolemia, sepsis, heart failure and presence of vasodilator drugs. The patient was treated with calcium gluconate, sodium bicarbonate and sodium chloride (to oppose the effects of hyperkalemia on the cell membrane to minimize cardiac and neuromuscular toxicity), insulin and dextrose (to increase the transport of K+ from the extracellular to the intracellular compartment), and hemodialysis (to remove K+ from the body). At the end of the hemodialysis session, the patient was in a clinically good condition, blood pressure was 160/90 mm Hg and the serum K+ concentration was normal. The case appeared to suggest that extreme hyperkalemia may have direct effects on vascular resistance, causing hypotension and shock.

This study was carried out to determine the prevalence of hepatitis C virus (HCV) antibodies and the epidemiologic factors associated with HCV infection in patients with chronic renal failure before the onset of ESRD. Sex, age, type of renal disease, level of renal function, and history of blood transfusions and invasive procedures were analyzed in 226 patients with renal disease, compared with a population of 1,244 normal subjects and 124 patients with impaired immunity (patients having autoimmune diseases and receiving chemotherapy treatment). Eighteen seropositive patients with renal disease (prevalence, 7.9%) were found, which was significantly higher than the prevalence in the normal population (1.03% in blood donors, 0.98% in pregnant women; P < 0.001, chi 2). There was no significant association of sex, number of blood transfusions, or history of invasive procedures with the presence of HCV antibodies. The prevalence of HCV antibodies was higher (16.6%) in patients with glomerulonephritis compared with patients diagnosed with interstitial nephritis, pyelonephritis, nephrosclerosis, diabetes mellitus, polycystic kidney, and miscellaneous renal diseases (P < 0.01, chi 2). There was a higher prevalence of HCV antibodies in patients with creatinine clearance lower than 30 mL/min (13%) compared with patients with creatinine clearance higher than 30 mL/min (2.7%) (P < 0.01, chi 2). These data suggest that HCV infection may be associated with the pathogenesis of glomerulonephritis. Alternatively, glomerulonephritis or severe renal insufficiency may increase the likelihood of HCV infection.

Resistive index (RI) calculation on Doppler tracing of intrarenal arterial blood flow is a sensitive method for the early diagnosis of obstructive uropathy. However, the RI is not specific and can increase in a number of other conditions, e.g., old age, circulating endogenic factors or drugs, other nephropathies. The authors investigated RI usefulness and accuracy by measuring it both before and after the radiologic treatment of acute urinary obstruction in 21 patients, 9 of whom had chronic renal failure due to other causes, i.e., hypertension, diabetes and chronic pyelonephritis. The clinical conditions of the patients limited the feasibility of RI measurements before and after nephrostomy to 66%. In 22 kidneys in 17 patients examined before nephrostomy, the RI ranged 0.63 to 0.93 (mean: 0.80); when the obstruction was unilateral, the RI was always higher than in the contralateral kidney. In 25 kidneys in 18 patients examined after nephrostomy, the mean RI value was 0.68 (15% lower than before). Taking 0.7 as the cut-off value, RI sensitivity in detecting acute urinary obstruction was high (about 90%), while its specificity was low (about 50%); specificity increased (to about 80%) when other concomitant causes of increased intrarenal arterial resistance, e.g., other vascular or parenchymal nephropathies, were not considered. In some cases, the method was also useful in excluding the presence of recurrent obstruction after ureteral stent removal. In conclusion, Doppler US values of intrarenal arterial perfusion are indicative of acute urinary obstruction when they can be compared with those from the contralateral healthy kidney or when they can be measured, in the same patient, before and after decompressive nephrostomy. In other cases, other nephropathies and some technical limitations must be considered.

Red blood cells obtained shortly before and after a hemosorption session from 12 patients were studied in scanning electron microscope. The patients suffered from chronic renal failure and purulent intoxication consequent to urolithiasis and purulent pyelonephritis (10 cases), renal arteriosclerosis (1 case) and prostatic cancer (1 case). Before hemosorption number of discocytes measured 50.8%, while that of stomatocytes 37.3%. Spherocytes, echinocytes and knisocytes occurred in larger quantities. After hemosorption diskocytes amounted 67%, echinocytes and acanthocytes levels rose. The changes may be due to normalization of blood biochemistry after the hemosorption, and to sorbent effects on red cells.

From 1985 to 1991 the author operated on 21 bladder cancers, forming cross anastomoses on the upper urinary tracts. 19 patients underwent cystectomy. Stage T2, T3, T4 was diagnosed in 4.8%, 80.9% and 14.3% of the patients, respectively. Hydroureteronephrosis was detected in all the patients, chronic pyelonephritis developed in 16 (76.2%), chronic renal failure in 9 (42.9%). Upper and low transureteroureteronephrostomy (TUUN) was performed in 13 (61.9%), transureteropyelonephrostomy (TUPN) in 3 (14.3%), transureteropyelo-ureterosigmoidostomy in 5 (23.8%) patients. The latter technique implies successive connection of the kidneys with the sigmoid. This provided less exposure of one of the kidneys to the intestinal infection, urinary fistulas did not form. Two deaths in the postoperative period were due to metastases and thromboembolism. The authors believe that the best functional conditions for the kidneys are secured by upper TUUN, TUPN and transureteropyelo-ureterosigmoidostomy applicable in cystectomy and in normal tonicity of the upper urinary tracts.
