Sonograms of 43 patients with intrinsic and perirenal infectious processes are reviewed. Fourteen had acute
pyelonephritis
; three, suppurative
pyelonephritis
; two, focal
pyelonephritis
; six, renal abscesses; three, infected cysts; six, perinephric abscesses; six, pyonephrosis; and three, chronic
pyelonephritis
. Sonography had little diagnostic value except for the patients with perinephric abscess. However, it proved valuable as a guide for a percutaneous approach to obtain cells for histologic diagnosis, to obtain fluid to determine chemotherapy, and to perform antegrade pyelography and percutaneous nephrostomy.

A total of sixteen patients with urethral stricture and/or perineal urinary fistulae (water-can perineum) complicating gonorrhoea were seen at the Special Treatment Clinic, University College Hospital, Ibadan, Nigeria. The patients were aged between 25 and 80 years, and the latent period between the time of original attack of gonococcal infection and the development of complications varied from 4 to 50 years. The rate of divorce or marital separation is high among these patients with late sequelae of gonorrhoea. The factors responsible for the present higher incidence of early and late complications of gonorrhoea among patients in Nigeria and other tropical countries compared with their counterparts in Europe and North American include: (a) Lack of medical facilities in most rural areas; (b) Inadequate treatment of veneral diseases, including the urban areas where self-medication is practised on a large scale by the general population; (c) Illiteracy and ignorance of venereal diseases. The cases of watering-can perineum reported here, and the subsequent chronic
pyelonephritis
and hypertension, reinforce the plea for early and energetic treatment of acute gonorrhoea in Africa as well as large-scale control measures by the health authorities.

The authors report a rare case of bilateral xanthogranulomatous
pyelonephritis

Prostaglandin concentrations of cerebrospinal fluid (CSF) of 38 febrile patients (from infants up to adults) were compared with those of 19 afebrile adult control persons. CSF samples were extracted and the prostaglandins groups of the extract separated by column chromatography. Concentrations of prostaglandins of the E and F series were estimated by radioimmunoassay. In CSF of all feverish patients with meningitis, pneumonia, or
pyelonephritis
about 2-fold higher concentrations of prostaglandin E (PGE) were found that in those of the afebrile control persons. In contrast, concentrations of prostaglandin F (PGF) in adults and infants remained largely unchanged during fever; Solely, in 4 of the 8 babies examined, concentrations of PGF were also increased besides those of PGE. Repeated estimations of prostaglandin concentrations in CSF from the same patients showed, that concentrations of PGE, which had been elevated during fever, normalized after defervescence. The height of fever and the concentrations of PGE in CSF tended to correlate in a dose related manner. In correspondence with the results of animal experiments prostaglandins of the E series seem to act as mediators of fever during infectious diseases also in man.

The authors describe 5 cases with a pathology peculiar to the superior calyces due to vascular compression, observed from 1969 to 1975 among 938 urographic tests performed in the Pediatric Clinic of Florence. Three of these cases have been checked up to this date. In every patient the urographic tests show clear evidence of a vascular compression at the level of the right upper calyces, associated with stasis and/or ectasis. In two cases there is a symptomatology of abdominal pains; in the remaining 3 patients haematuria is revealed. It is important, particularly in children, to follow the course of the clinical and urographic features, in order to carry out a surgical intervention at the right moment, according to the evolution of the process. The chronic segmental (upper pole)
pyelonephritis
is the most dangerous evolution.

Urinary excretion of lysozyme was investigated in a group of 66 patients with various renal diseases, nephrolitiasis and urinary tract infections. The results obtained demonstrate that the amount of the enzyme excreted is related to the entity of tubular damage whereas is not with glomerular damage. No correlation was found between lysozyme excretion neither to the degree of proteinuria neither to the amount of leukocytes and bacteria in the urine. In patients with urinary infections urinary lysozyme increases only when there is a tubular injury of some entity. In 90 pediatric patients with urinary infection and
pyelonephritis
lysozyme in the urine was found only in two cases. Therefore urinary lysozyme determination cannot be considered for the detection of early tubular injury and is not a helpful diagnostic tool in urinary tract infections.

The cellular activity of circulating lymphocytes and lymphocytes isolated from the infected kidney of animals with experimental haematogenous
pyelonephritis
was evaluated. The incorporation of [3H-methyl]thymidine into DNA by lymphocytes was studied with mitogens such as phytohaemagglutinin (PHA), pokeweek mitogen (PWM) and goat anti-rabbit IgG (GARIG). Lymphocytes from infected kidney had a high baseline DNA synthesis compared to circulating lymphocytes from days 5 to 27 of infection. Infected kidney lymphocytes failed to respond to PHA, PWM, or GARIG, whereas circulating lymphocytes did respond to these mitogens. Uropod-bearing lymphocytes, which were shown to be T lymphocytes, were present from days 5 to 77 of infection. B lymphocytes, as determined by surface immunofluorescent technique, were present by day 12, coincident with the onset of local synthesis of antibody. These studies reveal that in
pyelonephritis
, the cellular response goes through sequential changes and indicate a dynamic interrelationship between T and B lymphocytes at an infected site.

The response of circulating and kidney lymphocytes from rabbits with experimental haematogenous
pyelonephritis
to somatic (O) antigen (lipopolysaccharide) from the infecting organism was evaluated. Lymphocytes were cultured for 3 days in the presence and absence of lipopolysaccharide from the infecting organism, Escherichia coli O75 and a heterologous organism. Circulating lymphocytes showed a significant response to the homologous lipopolysaccharide by day 5 of infection, and kidney lymphocytes responded by day 19 of infection but failed to respond after day 33. The lipid moiety of somatic antigen was required for the stimulation of lymphocytes since antigen preparations in which lipid was low or absent did not activate lymphocytes. B lymphocytes from kidney were stimulated by this antigen whereas both T and B circulating lymphocytes responded. Thus,
pyelonephritis
in rabbits is associated with the activation of a subpopulation of circulating cells which have specific receptors for the homologous antigen. B lymphocytes that are specifically activated by the homologous or O antigen then localize to the infected site.

Within 4 years 1400 children were investigated for urinary-tract infection in a long-term study. Children with manifest infection were treated and followed-up. In 59 children with chronic
pyelonephritis
159 recurrences were observed: 146 were reinfections (change of organism) and 13 relapses (organism unchanged). Serotyping of 0-antigens showed differences between children with chronic
pyelonephritis
and children with a single exacerbation within the observation period. Reinfection with resistant bacteria mainly occurred shortly after cessation of therapy.

We present a case of nephrotic syndrome complicating acute
pyelonephritis
in a 45-year-old man. His first attack of acute bacterial
pyelonephritis
had two unusual features: transient nephrotic syndrome and chronic recurrent episodes of papillary necrosis. The former, which lasted for two weeks, was characterized by edema, excretion of 7.7 g of urinary protein per 24 hours and hypoproteinemia (1.8 g per 100 ml). A percutaneous renal biopsy two weeks after the height of the nephrotic state showed normal glomeruli by light and electron microscopy and immunohistologic studies. Interstitial changes were noted. Over two years the patient has passed approximately 50 fragments, characterized as necrotic tissue containing tubular structures. He has no evidence of diabetes mellitus, urinary-tract obstruction or ureteral reflux, analgesic abuse or atypical vasculitis. He is afebrile but has recurrent bacteriuria despite antibiotics. This case demonstrates that acute
pyelonephritis
must be added to the list of diseases causing the nephrotic state.
