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.

Trigonal-colonic anastomosis for diversion of urine into the colon was performed in 12 clinically normal dogs and in 10 incontinent dogs with diseases of the urinary bladder or urethra. Dogs were studied from 1 to 30 months after surgery. The surgical procedure was technically satisfactory. Fifteen of 22 dogs were studied with intravenous urography, and only 1 case of hydronephrosis was found. Pyelitis was a common histopathologic finding in both groups of dogs. Pyelonephritis developed in 30% of dogs, regardless of duration of anastomosis. Glomerular filtration rate was reduced in all dogs studied, but renal failure was infrequent. Values for blood urea nitrogen and serum inorganic phosphorus were elevated due to intestinal recycling of nitrogenous products and phosphate. Electrolyte imbalances were not a problem, but gastrointestinal disturbances developed in 3 of the 10 diseased dogs. Six of 10 diseased dogs survived from 9 months to more than 3 years. Trigonal-colonic anastomosis appears to be a satisfactory salvage procedure for incontinent dogs with diseases of the urinary bladder or urethra that do not respond to other forms of therapy.

Corynebacterium renale type I (strain 115), 1.7 X 10(7) to 4.5 X 10(7) organisms, introduced intravenously into mice disappeared from the blood less than 24 h after inoculation and did not produce pyelonephritis. The same strain, 1 X 10(7) to 5 X 10(7) organisms, inoculated into the urinary bladder of mice was not recovered from the blood in any of the mice, but caused pyelonephritis accompanied by ureteritis and cystitis in 16 of 21 (76%) mice. Pyelonephritis and cystitis in mice were histopathologically similar to those found in cows. The antibody response was observed only in the mice with pyelonephritis or pyelitis, but not in those with only cystitis or in those without lesions, as found in cows. Similar diseases were produced in mice by C. renale types II and III but less frequently than by type I. It is suggested, therefore, that mice may be useful in the study of bovine C. renale infection.

In 17 girls and 5 women with urinary tract infection and low-pressure reflux we performed 23 bladder-washout-tests. 12 were interpreted as supravesical, 11 as vesical bacteriurias. All patients with vesical bacteriurias had a normal IVP. The majority of patients with supravesical bacteriurias had clubbing and scarring. The possibility of interpreting the supravesical bacteriurias as a sign for pyelitis rather than pyelonephritis is discussed.

During the clinical trial of N1-(4,5-dimethyl-2-oxazolyl)-sulfanilamide (sulfamoxole) and 2,4-diamino-5-(3,4,5-trimethoxy-benzyl)-pyrimidine (trimethoprim) (CN 3123, Nevin, Supristol) results from 925 treated cases of bacterial infections of the urinary organs were documented. The analysis revealed the following conclusions: 1. On the basis of all the assessable cases, there was no clinical effect in less than 10% of patients and no bacteriological effect in only 13% of patients. The therapeutic response was clinically good in 76% and bacteriologically good in 68% of the patients. The rest of the patients showed a fair clinical response, that is to say they showed a definite improvement in the clinical picture, or some bacteriological response, i.e. a definite reduction in the organism counts or, in mixed infections, not all the strains of pathogen were eradicated. 2. There was a higher success rate in acute urinary tract infections which had not previously been treated than in chronic or previously treated cases. 3. The therapeutic results in the principal indications were as follows: Pyelonephritis: 73.9% good and 16.5% fair effect clinically; 63.6% good and 21.6% some effect bacteriologically. Pyelitis: 81.1% good and 18.9% fair effect clinically; 70.4% good and 25.9% some effect bacteriologically. Cystitis: 81.3% good and 8.6% fair effect clinically; 68.9% good and 17.6% some effect bacteriologically. Postoperative urinary tract infections: 98% good effect clinically and bacteriologically. Infections of the urinary organs (not specified in more detail): 71.8% good and 16.1% fair effect clinically; 65.0% good and 18.8% some effect bacteriologically.

Haematogenous pyelonephritis was induced in rabbits using Escherichia coli 06:K13:H1 bacteria and the amounts and avidities of antibodies to the 06 antigen were analysed by the ammonium sulphate precipitation technique of Farr. In a group of six animals preimmunized with E. coli 02:K2ab:H1, five developed pyelonephritis and one pyelitis, as determined by histological examination. All aminals showed a considerable antibody response to E. coli 06 antigen during the infection. The animal with pyelitis gave a slightly smaller response than the others. The antibody avidity showed a pronounced variation. In a second group of six rabbits not preimmunized, five animals developed pyelonephritis. The titres of antibodies against E. coli 06 antigen increased during the infection inall of the six animals. However, the increase was significantly smaller than for the animals preimmunized with E. coli 02:K2ab:H1 (P smaller than 0.01). The pattern of the antibody avidities in this group was also heterogenous. The results are consistent with previous findings that exposure to serologically heterologous E. coli bacteria can enhance the development of the homologous antibody titres. This could be of relevance for serological diagnostic work as well as in the determination of the protective capacity of the antibody.

Renal emphysema is a rare and severe infection, that constitutes two clinical entities: emphysematous pyelonephritis and emphysematous pyelitis. We report a case in which the gas is localized both in the collecting system and in the parenchyma of the kidney. In our experience the percutaneous renal drainage has revealed to be able to dominate the infection but not to preserve renal function.

To clarify the usefulness of histopathology in evaluating invasiveness during acute cystitis and pyelonephritis in a mouse model of urinary tract infection, findings from bladder and kidney sections of mice inoculated transurethrally with Escherichia coli were compared with results of bladder, kidney, spleen, and blood cultures and with changes in peripheral blood leukocyte counts. All of the 14 bladder histopathologic abnormalities evaluated were significantly associated with a positive bladder culture, and 7 were associated with splenic infection. Histopathologic features of cystitis were present in some culture-negative bladders. Eleven of 12 renal histopathologic abnormalities evaluated were significantly associated both with a positive kidney culture and with splenic infection, and two correlated with the development of peripheral leukocytosis. Histopathologic features of pyelitis and nephritis permitted culture-positive kidneys to be categorized as exhibiting colonization only, pyelitis only, or pyelitis plus frank nephritis and demonstrated that some culture-negative kidneys exhibit signs of pyelitis and nephritis. These findings suggest that detailed, semiquantitative histopathologic evaluation can add to quantitative cultures in the assessment of bacterial urovirulence in the mouse model of ascending urinary tract infection.

We report three cases of emphysematous pyelonephritis, all of them associated with perinephric emphysema, and one case of emphysematous pyelitis to demonstrate the value of computerized tomography (CT) in both diagnosis and patient management. The differentiation between air in the collecting system (emphysematous pyelitis), air within the parenchyma (emphysematous pyelonephritis), and air in the perinephric space (perinephric emphysema) may have significant prognostic (survival) and therapeutic (medical vs surgical) implications. Computerized tomography is currently the best method for demonstrating intrarenal air and for characterizing the location of that air (intracalyceal, intraparenchymal, perinephric, or pararenal).

Different strains of E. coli, that were isolated during years 1986-1990 from 217 urine samples in patients with asymptomatic bacteriuria, cystitis, cysto-pyelitis and pyelonephritis, appeared to be more frequently haemolytic (34.5%) than strains of E. coli isolated from faecal samples in patients with acute enteropathy. It was confirmed that the haemolysin production occurs during log -phase of bacterial growth. The degree of haemolysis can vary widely according to the strain involved. Agglutination tests, using 53 O-antiserum, showed a great variety of serogroups. Some of them (04, 018, 022) are prevalent among the haemolytic strains isolated from urine; some others (055, 0111, 075) are prevalent among the anhaemolytic strains isolated from urine and faeces.
