Chronic pyelonephritis is the most common renal disease of old age. The number of registered cases of this disease is below current diagnostic possibilities, since chronic urinary tract infection and chronic pyelonephritis still too rarely play a role in differential diagnostic considerations. Because of the insecure reliability of anamnesis and complaints reported by the patients the uroscopic examination of the urine and bacteriologic diagnostics are of special importance. These examinations can be carried out in general medical practice and they will lead to a diagnosis of chronic pyelonephritis with relatively high probability.

The adhesion of Escherichia coli to human urinary tract epithelial cells was inhibited by commercial gamma globulin, the total immunoglobulin fraction of human breast milk and urine, as well as the isolated immunoglobulin G and secretory immunoglobulin A fractions of urine from patients with acute pyelonephritis. Urinary anti-O6 antibodies reduced the adhesion of several O6 strains. Absorption of antibodies to the lipopolysaccharide of the adhering strain markedly decreased the antiadhesive capacity of all the immunoglobulin preparations, whereas elimination of antibodies to the capsular polysaccharide antigen consistently had a small but not significant effect. When urine was absorbed with whole, live bacteria of the patients' infecting strains, the antiadhesive effect completely disappeared. Absorption with bacteria lacking pili only partially reduced this effect.

An ultrasound examination performed on a young woman with a long history of urinary tract infection demonstrated multiple subcapsular sonolucencies suggestive of multiple abscesses. The combination of the ultrasonic appearance, the clinical history, and a large nonfunctioning kidney with calculi on intravenous pyelography allowed us to suggest the diagnosis of xanthogranulomatous pyelonephritis. Ultrasound plays an even greater role in patients who are allergic to iodinated contrast material in whom intravenous pyelograms and arteriograms may be contraindicated.

The present paper is an investigation into the diagnostic value of renal phlebography for differentiating between arteriographically hypo- and avascular malignant lesions in the kidney and benign renal masses. In three examinations carried out on eight patients with renal masses, phlebography was of crucial diagnostic importance. In ten renal cysts a presumptive diagnosis made by arteriography was confirmed by phlebography. In another eight renal cysts, a case of haemorrhagic pyelitis and in two cases of unilateral pseudotumerous pyelonephritis, phlebography was of no value.

A case of an unusual type of granulomatous lymphadenitis, initially suspected of being a malignant lymphoma, is reported. Histologically, this lesion shows a striking xanthomatous appearance, due to collections of foamy histiocytes interspersed with chronic inflammatory cells, and resulting in a storage-like aspect. Evidence indicates that this process merely represents the reabsorption and healing phases of an acute suppurative lymphadenitis, with histopathologic features comparable to those of xanthogranulomatous pyelonephritis. The term xanthogranulomatous lymphadenitis is suggested for this previously inadequately described lesion, and the likely non-specific degenerative character of the xanthomatous response is stressed.

Hypertension in children has been reported with increasing frequency because of increased awareness of its occurrence by clinicians. Renovascular lesions have been stressed in the past. However, in recent years, a number of nonrenovascular renal lesions have received attention and form the basis for this report. Unilateral chronic atrophic pyelonphritis, segmental unilateral pyelonephritis, the Ask-Upmark kidney, and unilateral renal hypoplasia have been associated with curable hypertension. The subject of juxtaglomerular cell hyperplasia, which has variably been reported in these cases, is reviewed. Ureteral obstruction, in the form of uretero-pelvic or ureterovesical junction obstruction, solitary renal cysts, the unilateral multicystic kidney, renal trauma, and renal tumors (Wilms' tumor and juxtaglomerular cell tumors) may also be associated with hypertension in children. Pheochromocytoma must be ruled out in all cases. Because of renewed interest, these nonrenovascular renal causes of hypertension are now likely to be diagnosed with increased frequency.

The basic non-invasive investigation of renal space occupying lesions by excretion pyelography was coupled with ultrasonic scanning. Forty-one patients who have undergone isotopic section scanning as part of their investigative assessment were studied. The conditions investigated included solitary cysts, polycystic kidneys, renal tumours, tumefactive xanthomatous pyelonephritis, renal infarct and non-functioning kidneys. An analysis of the accuracy of isotopic section scanning in these different pathological states was made. Computerised isotopic section renal scanning offers a new non-invasive renal investigative technique.

Urinary tract infections can be found in either sex at any age. While the majority occur in adult females as acute cystitis, recurrent symptomatic bacteriuria, or asymptomatic bacteriuria, adult males with prostatitis or acute pyelonephritis and children with symptomatic urinary tract infections comprise a considerable portion of patients seen. Management in pregnant females or in males with indwelling catheters or before prostatic surgery presents special problems. The choice of drug and dosage schedule should vary according to the infecting agent and the clinical state of the patient.

We herein describe 2 cases of emphysematous pyelonephritis, which can be added to the 42 cases previously reported. Both female patients were diabetic and had Escherichia coli infections. Both had ureteral obstruction and underwent nephrectomy to survive septic and/or azotemic crises. Timely surgical intervention after unsuccessful antibiotics and conventional medical measurements is life-saving.

Amongst the various methods suggested for the topographical diagnosis of urinary tract infection, the study of various fractions of lactico-dehydrogenase in the urine would appear to be particularly valuable. Study of 44 subjects with a significant urinary infection, compared with an identical group of subjects free of urinary infection, showed that in those with pyelonephritis fraction 5 was significantly (p less than 0.001) higher than in those with a lower urinary tract infection. However this was valid only in the absence of renal insufficiency. Combined study of immunological techniques (urinary antibodies revealed by immunofluorescence and serum antibodies) shows that these techniques are complementary and make it possible to exactly localise the site of a urinary tract infection. In relation to immunology, enzymology has the advantage of being suitable for use during periods at which bacteriological examination of the urine is negative, and hence is useful in following the influence of treatment.
