The outcome of uni- or bilateral chronic pyelonephritis was retrospectively studied in 26 patients. The material consists of all positive intravenous urographies performed at the hospital during three years in the 1950s and the follow-up time was approximately 30 years. Development of uraemia or death owing to renal disease occurred in 15% of the patients. The majority of patients with unilateral pyelonephritic changes showed unchanged scarring during the years, while progressive scarring mainly occurred in younger patients. The development of renal failure was found in patients with extensive bilateral scarring, proteinuria and hypertension.

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.

During 1974-1984 altogether 481 patients were treated for end-stage renal disease (ESRD). Eight patients, five women and three men, with chronic pyelonephritis as the primary cause of ESRD, had staghorn urinary calculi as a predisposing factor for renal failure. These eight patients were studied retrospectively concerning epidemiological and bacteriological aspects, the treatment of the stone disease, and the development of uraemia. Anatomical and metabolic abnormalities such as bladder outlet disturbances, primary hyperparathyroidism, phenacetin abuse or metabolic stone disease were found in six patients. The women had all been infected with Proteus mirabilis, whereas the men had been infected with various microorganisms. The average time taken for the development of ESRD, estimated from the first sign of renal impairment, was 7.4 +/- 2.9 (SD) years. Five patients had died before this study commenced. One of the patients still alive was on dialysis treatment. Two patients who were doing well without dialysis were stone free and had sterile urine after successful pyelolithotomy. It is concluded that the prevalence of infectious urinary calculi as a cause of uraemia in patients with ESRD is low. The time taken for uraemia to develop is short in these patients and they often have anatomical abnormalities. Proteus is commonly found in this group of patients. Patients with staghorn calculi, urinary tract infection and impairment of renal function are at risk of developing uraemia.

Some neurophysiological techniques have been employed in clinical nephrology to record abnormalities of nervous conduction in central and peripheral pathways. The electrical monitoring on the peripheral and central nervous systems has allowed the detection of uremic neural injury, the diagnosis of specific electrophysiological abnormalities, the evaluation of various treatments employed and the identification of those abnormalities that uremia can induce. A group of 156 subjects subdivided into four groups were examined: 100 healthy subjects (64 M, 36 F); 56 patients (21 glomerulonephritis, 14 pyelonephritis, 5 nephrolithiasis, 5 polycystic kidney, 4 nephroangiosclerosis, 7 undetermined) with chronic renal failure treated with a conventional low nitrogen diet (CLND, 0.6 g/kg b.w./d. of proteins), 8 of whom passed from CLND to a very low nitrogen diet supplemented with alpha-keto-analogues; a group of 22 of these 56 underwent a regular dialysis treatment for 12 to 15 hours/weekly for 40.5 +/- 10.2 months. Three patients of the CLND group and 13 patients underwent renal transplantation after a variable period of RDT. In the uremic patients we found different populations of motor unit potentials; a decreased MNCV was found in 35% of the CLND patients, RDT patients had slowed MNCV in 42%. The SNCV was compromised more frequently than the MNCV. An increased duration of evoked potentials was sometimes observed in CLND and RDT patients inducing us to consider this a hallmark of uremic syndrome. The alpha-keto-analogues and HD/HP treated patients showed an improvement in several features.(ABSTRACT TRUNCATED AT 250 WORDS)

A 14-year-old Friesian breeding mare had strangury, depression, inappetence, neutrophilia and uraemia. Its urine had a low specific gravity and contained protein, blood cells and bacteria. Rectal examination showed that both kidneys and ureters were enlarged. Post mortem examination confirmed the diagnosis of pyelonephritis and revealed that small tumours in the vulva were probably the cause of the uropathy.

Three experimental models of vesico-sigmoidostomy are studied (model-1, end to side V-S plus urethral ligation, model-2, end to end V-S, in "Y of Rous" plus urethral ligation and model-3, vesico-sigmoidoplasty), with aim of reproducing chemical imbalance observed in human subjects with ureterosigmoidostomy. Authors have evaluated clinical biochemical (serum acido-base balance, Cl, Na+, K+, BUN, creatinine, ammonia and albumin), and histologic variables in the first, third and fifth month after operation in 225 rats. Animal of model-1 presented more frequently than model-2 and model-3, alterations (hyperchloraemic acidosis, uraemia, hyperammonemia and hypoalbumin) as well as affectation of upper urinary system for acute or chronic pyelonephritis.

The sodium and potassium concentrations of the red blood cells and the plasma in 38 children with pyelonephritis (19 acute, 10 chronic and 9 healed), 5 children with uraemia, and 20 children with nephrotic syndrome were compared with those of control children. The red blood cell sodium concentration was lower in patients with acute pyelonephritis, uraemia, and steroid-treated nephrotic syndrome, and higher in those with chronic pyelonephritis and nephrotic syndrome not treated with steroids. Except in uraemic cases, these alterations were not accompanied by plasma sodium and potassium changes. The results might be explained by pathological Na+ and K+ transport processes in the red cell membrane. The possible role of extracellular fluid volume changes, sodium loss and water retention are discussed.

Classic Graves' disease associated with thyroid-stimulating hormone receptor antibodies developed in a woman undergoing regular hemodialysis for uremia from chronic pyelonephritis. Her condition responded well to treatment initially with carbimazole and then an ablative dose of sodium iodide I 131 therapy. To our knowledge this is only the second documented case of hyperthyroidism in a patient with chronic renal failure, and it demonstrates that conventional forms of therapy are efficacious and safe.

Bladder washout (BWO) and antibody-coated bacteria (ACB) tests were performed on 25 patients with radiological and/or clinical evidence of chronic upper urinary tract infection (UTI) and 12 patients with asymptomatic bacteriuria. Using a traditional single-washout procedure, the BWO test gave equivocal results in many cases of chronic pyelonephritis; this seemed mainly due to the lack of complete bladder sterilization. A modified procedure, including double sterilization and irrigation, biochemical typing of isolated bacteria, and evaluation of temporal pattern of bacteriuria recurrence, was then introduced. Although preliminary results of the modified BWO test demonstrated a general improvement in the diagnosis of the infection site, it seemed rather difficult, at least in chronic UTI, to establish localizing criteria based on definite numeric changes in bacterial counts after washout.

An analysis of post-mortem examination data on 600 cases of cancer of the prostate showed that among the most frequent complications were ascending pyelonephritis (51.7%), focal pneumonia (42.8%) and cachexia (36.7%). Deaths were caused mainly by progression of cachexia (24.3%), uremia (24.3%) and focal pneumonia (19.5%). Only a small percentage of patients died from postoperative complications and concomitant pathology.
