Urinary diversion by implantation of the ureters into an isolated segment of jejunum was evaluated in eight clinically normal male dogs. Total cystectomy and subtotal intracapsular prostatectomy were performed, and the intestinal loop was sutured to the prostatic remnant. General health, renal function, acid-base balance, urinary tract infection, and urinary continence were monitored during observation periods of 4 to 30 weeks. All dogs survived the observation period and seven were in excellent general health at the time of euthanasia. Six of the 16 ureterointestinal anastomoses were complicated by complete ureteral obstruction. Absorption of urea from the intestinal loop was speculated as the reason for significant increases in serum urea nitrogen concentrations in all of the dogs. Serum creatinine concentrations generally remained within the normal range, but were significantly increased from preoperative baseline values by week 30. There was dilation of 12 renal pelves and ureters in seven dogs. Urine bacterial cultures were positive in six dogs, but histologic evidence of pyelonephritis was present in only five kidneys. Ejaculation was not affected by the procedure, but epididymitis was present in five dogs. The dogs could urinate consciously and did not dribble urine continuously; however, they urinated hourly. While the procedure was well tolerated by the dogs, the frequency of urination makes this technique unacceptable for most household pets.

Structural aspects of copper chloride crystallization of the urine of patients with pyelonephritis and glomerulonephritis were studied by electron microscopy. It was found that admixtures of urea, creatinine, potassium and, possibly, sodium contained in the urine of patients initiate the formation of copper chloride crystals of different sizes, their shape changes, dendritic and spherolithic crystallization occurs. Results may be used as supplementary differential diagnostic signs of glomerulonephritis and pyelonephritis.

Corynebacterium group D2 (CGD2) is a slow-growing, urea-splitting, multiantibiotic-resistant microorganism that is frequently isolated from urine samples and that, in certain circumstances, produces infection of the lower urinary tract (acute and chronic cystitis) and the upper urinary tract (pyelonephritis). This paper analyzes (by means of a retrospective and partially prospective clinical protocol) our experience with 82 patients with CGD2 bacteriuria. The infection was symptomatic in 62% of cases, and the clinical diagnoses included acute and chronic cystitis and pyelonephritis with or without bacteremia. Because CGD2 infection of the urinary tract may require specific antimicrobial treatment and because CGD2 is a fastidious microorganism, we recommend prolonged incubation of urine cultures (up to 48-72 hours), especially if the routine culture is negative, when patients are symptomatic, have alkaline urine, or have struvite crystals in the urine sediment.

Diagnostic potentialities of the crystallo-optic++ analysis of cupric chloride crystallographs++ were studied in 76 children with pyelonephritis and in 50 children with glomerulonephritis. The structural and morphological characteristics of cupric chloride crystallization under the influence of the urine from children with pyelo- and glomerulonephritis may serve as the additional differential-diagnostic signs of the diseases. The use of raster electron microscopy widens the diagnostic potentialities of the crystallographic method. Different dimensions of the little crystals formed as a result of isomorphic replacement of copper atoms by potassium ions (and, possibly, by sodium ions) and in the presence of urea and creatinine underlie the differences in cupric chloride crystallographs.

The ability of bacteria to adhere to the epithelial cells of hosts has been shown to be mediated by adhesins. Many of these show readily demonstrable haemagglutinating activity. Of 109 Escherichia coli strains isolated from patients with symptomatic urinary tract infection, 11 (10.1%) were identified by their haemagglutinating properties as being P fimbriated, which was confirmed by the latex bead test. Other classes of adhesins, termed X and "other", were found in mannose resistant haemagglutinating E coli strains, which represented 4.6% (5) and 0.9% (1), respectively, of all the strains. Type 1 fimbriae were found in 40.4% (44/109) of E coli strains grown on colonising factor agar (CFA) medium. This incidence was 12.8% higher (53.2%, 58/109) when the strains were grown on CFA supplemented with urea, which suggested that urea may modulate the expression of type 1 fimbriae. Conversely, this phenomenon was not seen in P fimbriated E coli. Assays using trypsinised and non-trypsinised human erythrocytes showed no difference in the percentage of strains that haemagglutinated. Regarding the clinical correlation of fimbriated E coli strains, the X mannose resistant haemagglutinating adhesins were also found to be of clinical relevance. P fimbriated E coli strains were isolated from five out of the eight patients with pyelonephritis.

Fifty-one cases of bovine pyelonephritis were investigated. The annual prevalence rate for 2089 cows was 1.6% in 1987 with a mean interval from calving to onset of cases of 82.9 days. Multipara were at higher risk. Loss from pyelonephritis was 33.3% of all affected cows, and relapse occurred in 9.4% of apparently recovered animals. Serum creatinine and urea concentrations were of high prognostic values. Odds ratios being culled for cows with levels of creatinine above 1.5 mg/dl (132.6 mumol/l) and of urea above 100.0 mg/dl (16.7 mmol/l) were 104.0 and 60.0 respectively compared with those with lower values. Haematological results were of no diagnostic value. Odds ratio for cows with no post-parturient uterine diseases having pyelonephritis was 8.9 compared with infected cows treated at calving with antibiotics.

Microbial ureases hydrolyze urea to ammonia and carbon dioxide. Urease activity of an infectious microorganism can contribute to the development of urinary stones, pyelonephritis, gastric ulceration, and other diseases. In contrast to these harmful effects, urease activity of ruminal and gastrointestinal microorganisms can benefit both the microbe and host by recycling (thereby conserving) urea nitrogen. Microbial ureases also play an important role in utilization of environmental nitrogenous compounds and urea-based fertilizers. Urease is a high-molecular-weight, multimeric, nickel-containing enzyme. Its cytoplasmic location requires that urea enter the cell for utilization, and in some species energy-dependent urea uptake systems have been detected. Eucaryotic microorganisms possess a homopolymeric urease, analogous to the well-studied plant enzyme composed of six identical subunits. Gram-positive bacteria may also possess homopolymeric ureases, but the evidence for this is not conclusive. In contrast, ureases from gram-negative bacteria studied thus far clearly possess three distinct subunits with Mrs of 65,000 to 73,000 (alpha), 10,000 to 12,000 (beta), and 8,000 to 10,000 (gamma). Tightly bound nickel is present in all ureases and appears to participate in catalysis. Urease genes have been cloned from several species, and nickel-containing recombinant ureases have been characterized. Three structural genes are transcribed on a single messenger ribonucleic acid and translated in the order gamma, beta, and then alpha. In addition to these genes, several other peptides are encoded in the urease operon of some species. The roles for these other genes are not firmly established, but may involve regulation, urea transport, nickel transport, or nickel processing.

Serum gamma-glutamyltranspeptidase (GGTP) and alpha-amylase clearance were determined in a total group of 90 patients of whom 60 with renal diseases and 30 with extrarenal diseases. The renal patients were distributed, according to diagnosis in the following groups: acute glomerulonephritis, chronic glomerulonephritis, acute pyelonephritis, chronic pyelonephritis, nephrotic syndrome and manifest chronic renal failure. The 30 controls were hospitalized for different extrarenal diseases such as: pneumonia, gastroduodenal ulcer, arterial hypertension stage I and angina pectoris. Serum GGTP assay was performed in 60 patients (40 renal patients and 20 controls) using Boehringer monotest kits and in 30 patients (20 renal patients and 10 controls) using Romanian kits (I.C.C.F.). No changes suggesting a particular type of nephropathy were observed. The results obtained by using the two types of kits for the serum GGTP assay have proved to be very close. Alpha-amylase clearance was determined in all the patients with Spofa (R.S.C.) tablets concomitantly with the urea and creatinine clearance. Important decreases of alpha-amylase clearance in concordance with decreases of urea and creatinine clearances were observed in all the patients with severe renal failure. More moderate decreases of alpha-amylase clearance were observed in the patients with acute and chronic glomerulonephritis. The utility of this clearance as a test of glomerular filtration and sometimes as a prognostic test, is discussed.

In 19 urological patients with pyointoxication and urosepsis 49 plasmaphereses for the purpose of detoxication were performed in the complex with other therapeutic measures. The causes for the pyoseptic complications were as follows: urolithiasis in connection with acute pyelonephritis, acute pyelonephritis (among others in pregnancy, cystic renal dysplasia, carcinoma of the urinary bladder), renal insufficiency in the terminal stage. The treatment of these diseases with haemodialysis and haemoperfusion was complicated by a pyosepsis. Two methods of the plasmapheresis were used: the intermitting plasmapheresis with use of a refrigeration centrifuge K-70 (GDR) and the permanent membrane plasma separation with the device A2008 RG of the firm "Fresenius" (FRG). The plasma perfusion was experimentally proved and in 5 cases used on 5 columns with activated charcoal. The efficacy of the plasmapheresis and the plasma perfusion was apart from the clinical condition judged according to the values of the middle molecules in the blood, or urea, creatinine and the normalisation of the hypoproteinaemia as well as of the humoral immunity. To this are added the increase of diuresis, the normalisation of the haematological parameters and the bacteriological findings of blood and urine. Furthermore, several pathogenetic mechanisms of the positive effect of the plasmapheresis were analysed (mechanic removal of bacteria and their toxins, effect of "deplasmation" with tissue dehydration, improvement of the functional state of the kidneys within the first 3-4 days: reduction of the azotaemic intoxication, the DWS-syndrome, improvement of the rheological properties of the blood and of the microcirculation, increase of the antitoxic function of the liver).(ABSTRACT TRUNCATED AT 250 WORDS)

Ureterocolonic anastomosis (UCA) was performed in 10 dogs with transitional cell carcinoma of the urinary bladder trigone or the urethra, or both. All grossly visible tumor was excised. All of the dogs recovered from anesthesia and surgery and had anal continence with no urine leakage. One dog died of undetermined causes 7 days after surgery. Nine dogs survived 1 to 5 months. The owners of eight of the dogs considered their dog's quality of life to be acceptable. Four dogs were euthanatized because of neurologic disease, three of which also had nausea and vomiting. The neurologic and gastrointestinal signs may have been caused by hyperammonemia, metabolic acidosis, and uremia. Blood ammonia levels were elevated in two dogs with neurologic signs. Hyperchloremic metabolic acidosis that was reversible with bicarbonate therapy was diagnosed in five dogs. All of the dogs were azotemic because of intestinal recycling of urea. Serum creatinine concentrations increased in four dogs after surgery. Drug-induced renal disease may have developed in two dogs. Pyelonephritis developed in five kidneys, two of which had outflow obstruction and two had bilateral hydroureteronephrosis before the UCA. In this small number of dogs, surgical excision of transitional cell carcinoma was not curative with six dogs having confirmed metastatic lesions at the time of death.
