All cases of persistent renal failure in infants less than 1 year of age were reviewed to determine whether the prognosis has improved equally for infants as for adults. During a ten-year period, 52 infants were treated by applying uniform therapy; 28, more than half, were less than 4 weeks old. All cases were separated into two groups; 19 infants without and 33 infants with congenital renal or urinary tract anomalies. In 20 patients of the latter group, additional serious anomalies of other organs were present. The age distribution was strikingly different: in 18 of 21 infants, renal anomalies were present, as diagnosed on the first day of life. In contrast, only 3 of 11 infants, 4 to 12 months old, had urinary tract anomalies. In infants without renal anomalies, renal failure was caused by hypotension or shock in 10 of 19 cases, by
pyelonephritis
or sepsis un 6 of 19. Of this group, eight infants (42%) recovered completely, nine (47%) died. Death occurred within one to two days of hospitalization in all but three cases, caused by shock or sepsis. In this group medical problems that are amenable to therapy have caused either renal failure or contributed to the infant's death. In infants with renal or urinary tract anomalies, renal failure was caused by renal dysplasia or agenesis in 16 of 33 infants, by urinary tract obstruction in 12 of 33. Only three patients (9%) recovered, all older than 4 months, 20 (61%) died, and 10 are living with signs of
chronic renal failure
. Death usually occurred within one week of hospitalization and, in 16 of 20, it was caused by renal failure and multiple additional anomalies. The multiplicity and complexity of the congenital anomalies in most instances precluded effective, lifesaving therapy. Renal failure in infants is still a serious disease accompained by a high mortality rate in which therapeutic possibilities are limited. No improvement in prognosis can be expected in the near future. Pediatrics, 59:987-994, 1977, RENAL FAILURE, CONGENITAL RENAL ANOMALIES, INFANT, ISCHEMIC RENAL DAMAGE.

The erythrocyte cholesterol, total phospholipid and individual phospholipids content have been determined in patients with
chronic renal failure
, resulting from glomerulonephritis and
pyelonephritis
. The rise in total phospholipid, confined predominantly to the sphingomyelin and lecithin classes was found. It was often accompanied by decrease in the phosphatidylethanol-amine content. The cholesterol/phospholipid ratio was found to be reduced. The excessive lipid loss during incubation of erythrocytes in glucose-rich medium has been observed in some patients.

Vesicoureteric reflux was found unexpectedly during routine investigations before renal transplantation in 12 patients with chronic glomerulonephritis and in one with hypertensive nephrosclerosis. They had all received long term hemodialysis treatment for nine to 106 months (mean 47 months) at the time of micturating cystourethrography (MCU). Four of the patients had previously had a normal MCU indicating that reflux developed after onset of
end stage renal failure
. The cause of reflux is obscure. It was not related directly to defunctioning of the urinary tract as several patients had daily urine volumes in excess of 300 ml. Infection, another potential cause, was uncommon in patients with reflux. Histology of the excised ureters showed abnormality in most cases with loss of the normal mucosal folds and submucosal cellular infiltrate and fibrosis. These changes are also unexplained. In this group of patients nephroureterectomy for reflux in anticipation of renal transplantation was associated with considerable morbidity. A minimal estimate of the incidence of reflux in chronic glomerulonephritis was 11%. We suggest that in this group and in patients with renal diseases other than chronic
pyelonephritis
reflux alone does not constitute sufficient indication for nephroureterectomy before transplantation to warrant the risks of major surgery.

Vesicoureteral reflux was observed in 19 of 180 patients (10.5%) with end-stage
chronic renal failure
. The underlying disease in the patients with reflux was chronic glomerulonephritis in 8.3%, chronic
pyelonephritis
in 28.5% and renal hypoplasia in 40%. Reflux was bilateral in 13 patients and unilateral in six. Most likely bladder dysfunction due to uremia may have been the cause of the reflux.

In a total of 110 patients with
chronic renal failure
, 46.4% of the cases had a serum lipase activity exceeding 200 IU, the upper limit of the norm. The degree of reduction of renal function is positively correlated to the frequency of hyperlipasaemia as well as to the elevation of the lipase activity in serum. At a glomerular filtration rate (GFR) of less than 20 ml/min, hyperlipasaemia in chronic glomerulonephritis was found in 75%, significantly more frequent than in chronic
pyelonephritis
(46.8%). The frequency and degree of hyperlipasaemia was not influenced by haemodialysis. Significantly elevated serum lipase activities were also observed in experimentally produced
chronic renal failure
in the rat.

In a 38-year-old woman the process of developing
chronic renal failure
in Bournevill-Pringle's disease is described. The diagnosis is based on the typical skin lesions as well as the familiary affliction concerning four generations. Only in the fourth generation a brain involvement is detectable. In the presented case cystic mixed tumors of the kidneys are responsible for the renal insufficiency, combined with consecutive
pyelonephritis
. According to the changing clinical expressivity of this congenital disease it can be deduced, that Pringle's disease is in this case an abortive form of tuberous sclerosis. The basic lesion of tuberous sclerosis is hamartomatous tissue change. The brain, skin, bones and kidneys are the most commonly affected sites.

With the purpose of establishing the clinicopathologic correlation in
pyelonephritis
and to discard other interstitial nephrites, with present day morphologic criteria we analysed 63 casos that had been diagnosed as
pyelonephritis
, following Weiss and Parker's histologic criterion. The clinicopathologic diagnosis of
pyelonephritis
was confirmed in 12 cases; all of them showed obstructive uropathy and in most of them, there was
chronic renal failure
. Interstitial nephritis was established in 27 cases, all of them showing septicemia and almost half of the cases showed acute renal failure. Other 20 cases showed tubulointerstitial nephritis secondary to different types of glomerulopathies, fetal glomerulosclerosis, dysplasias, nephrophthisis, radiation nephritis and renal infarct. In 4 cases, the study of sections finer than the original, showed absence of histopathologic lesions. The results of the present study point out the main causes of confusion with the pathological diagnosis of
pyelonephritis
, the necessity to investigate predisposing uropathy in patients with urinary infection and stresses the importance to establish correlation with clinical and laboratory findings in cases with tubulointerstitial lesions.

The native kidneys in patients on dialysis or after transplantation tend to be overlooked until problems occur in relation to them. Their appearance can be variable and does not bear any consistent relationship to the cause of the renal failure; although in some cases, such as polycystic kidney disease, there are specific changes to be seen. Size can also be variable with little correlation to pathology in most cases. Acquired cystic disease of the kidneys is seen in up to 92% of long-term dialysis patients and also can be seen in patients with
chronic renal failure
. Proliferative changes occur in the kidneys which result in the development of cysts, adenomas and, in approximately 1% to 2% of dialysis patients, malignant lesions. It is probable that these changes are caused by a combination of factors, including circulating agents which are not cleared adequately by dialysis. There is some evidence that these changes are halted, or even reversed following a successful transplant. Problems with infection and hemorrhage may occur in patients with polycystic kidney disease. Problems with infection may also occur in patients with calculi, with longstanding
pyelonephritis
, or reflux.

Pathogenic bacteria coexist with their hosts in a relationship which most frequently allows persistence of the bacteria without causing disease. In a small proportion of colonised individuals the complex mutual interaction between microbe and host is upset, leading to disease in the host. The investigation of bacterial virulence determinants and their genetic control at the molecular level is an important facet of the development of strategies to combat disease. This review focuses on the investigation of a single pathogenic organism as a means of illustrating modern approaches to the investigation of bacterial virulence. The importance of uropathogenic Escherichia coli in causing acute and recurrent
pyelonephritis
with the consequent morbidity of
chronic renal failure
is well established.
Pyelonephritis
-associated (Pap) pili are likely to be critical virulence factors in uropathogenic E. coli. The evidence for their role in pathogenicity and the control of their expression at the molecular genetic level is discussed.

A 26 year old female, a case of
chronic renal failure
secondary to chronic
pyelonephritis
with renal osteomalacia, came with dimunition vision as the presenting complaint. She was found to have bilateral cataracts. All other known causes of cataract were excluded. Cataracts due to hypocalcaemia in
chronic renal failure
are a rare phenomenon.
