We report a case of xanthogranulomatous pyelonephritis in a cadaver kidney allograft. The patient had diabetic glomerulosclerosis. The predisposing factors that led to this condition included hyperglycemia, a previous rejection reaction and Escherichia coli urinary infection. Persistent fever, pyuria, bacilluria and a nonfunctioning allograft resulted in allograft nephrectomy. The diagnosis was made on histological examination. Diagnostic criteria for xanthogranulomatous pyelonephritis in the allografted kidney are similar to those in the native kidney.

The significance of Gardnerella vaginalis in urine was studied by comparing urine culture results, urinalysis data, and clinical findings. Over a two-year period, G vaginalis was reported in 2.3% of all urine cultures. Of 72 patients with pure cultures (greater than 10(4) cfu/mL), 43 patients (59.7%) were found to have G vaginalis urinary tract infections. Furthermore, four of the infected patients had pyelonephritis. Symptoms associated with G vaginalis urinary tract infections varied, and pyuria was detected in only 58% of the cases. Conditions associated with G vaginalis urinary tract infection included a history of recurrent urinary tract infections and/or instrumentation and upper urinary tract disease.

A 66-year-old female with bilateral ureteral tumors associated with chronic renal failure is presented. She received pan-hysterectomy due to uterine cancer in 1957. She was first referred to our clinic to make internal shunt under a diagnosis of chronic renal failure. In 1979, the diagnosis of neurogenic bladder and bilateral vesicoureteral reflux (rt; grade 3, lt; grade 1) was made. She was admitted to our clinic with complaints of macroscopic hematuria and a temperature of 39 degrees C on April 28, 1983. Cystoscopically, pyuria from the right ureteral orifice was found. Right retrograde pyelography revealed severe dilatation of the right ureter and renal pelvis with some filling defects. For drainage of pus retaining in the right renal pelvis, right percutaneous nephrostomy was made under the guidance of ultrasonography. After her general condition improved, right nephroureterectomy was performed under the diagnosis of right pyonephrosis on June 8, 1983. Right pyelonephritis and right ureteral tumor, grade 3, were pathologically demonstrated. After the operation, an invasive bladder tumor was detected on cystoscopy and ultrasonography, subsequently a total of 3,900 rad irradiation was given to the bladder tumor. She died of pulmonary edema 7 months later. Autopsy demonstrated a transitional carcinoma, grade 3, of the left ureter. Bilateral urothelial tumors of the upper urinary tract is rare, and to our knowledge only 29 cases have been reported in Japan.

In caring for women with acute dysuria, clinicians traditionally have relied on clinical findings to distinguish between acute pyelonephritis and "cystitis"; they have ordered urinalysis and urine culture regularly for patients with suspected acute pyelonephritis and ordered these tests inconsistently for patients with suspected "cystitis." Recent evidence indicates that "cystitis" may actually be any of six different clinical conditions, each of which is managed differently; subclinical pyelonephritis, lower urinary tract bacterial infection, chlamydial urethritis, other forms of urethritis, vaginitis, or dysuria without any urinary tract or vaginal infection. The distinction between these entities is made primarily from clinical findings. Urinalysis is also of great value in symptomatic patients; the presence of pyuria (and possibly indirect quantitation of pyuria by the leukocyte esterase test) is a reliable indicator of treatable infection, and its absence indicates infection is not present. In contrast, urine culture is of clear value only in patients with acute pyelonephritis or subclinical pyelonephritis.

Except for infections (pyelonephritis, abscess of the kidney), which cause symptoms such as pyuria, pain and fever, most diseases of the renal parenchyma were unknown in Greek and Roman antiquity. Even in the Renaissance they were not yet properly identified. Edema was generally thought to be related to liver disease. Proteinuria was discovered at the end of the 18th century. In 1827 Bright provided the first, almost complete clinical description of the various forms of acute and chronic glomerulonephritis and showed that they were accompanied by macroscopic changes in the kidneys. Between 1850 and 1885, Frerichs, Klebs and Langhans described the primary glomerular lesions. The amount of new knowledge acquired during the 20th century has been tremendous, and covers the mechanism of urine formation, the role of sodium retention in edematous states, the physiology and physiopathology of the renin-angiotensin-aldosterone system, the glomerular origin of the nephrotic syndrome, new methods of investigation, progress in histology and immunology, the discovery of many tubular syndromes, the introduction of antibiotics and antihypertensive drugs, and the development of dialysis and transplantation.

In a racially mixed community in Gisborne, New Zealand, the prevalence of asymptomatic (covert) bacteriuria of pregnancy was 9.6%. The prevalence in Maori women was 17.1% and in non-Maori women 4.7%. There was a higher prevalence of bacteriuria in the younger women. Escherichia coli was the infecting organism in 58 of the 72 women with bacteriuria. Twenty-five (44%) of the E. coli were resistant to ampicillin and amoxycillin. Fifty-eight (81%) of the women with bacteriuria also had pyuria. In 37 of the 44 women (84%) who received antimicrobial therapy, the infection was cured. Single dose therapy was just as effective as a course of treatment. In 14 of the 28 untreated women, the infection cleared spontaneously. Four of the 28 (14%) patients in the untreated bacteriuric group developed acute pyelonephritis. More patients with bacteriuria had anaemia and a low fetal birth-weight.

We studied 182 patients with chronic renal failure by urinalysis and urine cultures. Of the patients 27 per cent had significant bacteriuria (more than 10(5) per ml.), 38 per cent had significant pyuria (more than 10 white blood cells per high power field), 19 per cent had urinary tract infection and 7 per cent had symptomatic urinary tract infection. All 12 patients with symptomatic urinary tract infection had significant bacteriuria and 11 had significant pyuria, while 1 had 5 to 10 white blood cells per high power field. Incidences of urinary tract infection differed depending on the primary renal disease (12, 13, 41 and 67 per cent for chronic glomerulonephritis, diabetic nephropathy, polycystic kidney and chronic pyelonephritis, respectively). Among the patients with chronic glomerulonephritis no significant differences were seen in frequencies of bacteriuria and urinary tract infection between male and female patients or between those who did and did not undergo hemodialysis. Also, no significant correlation was seen between bacteriuria and daily urine output but pyuria was significantly more frequent in oliguric patients or those on hemodialysis.

Initial antibiotic therapy should be based on Gram's stained urine. For the elderly patient with acute symptomatic bacterial pyelonephritis caused by gram-negative aerobic bacilli, an aminoglycoside is recommended, eg, gentamicin, tobramycin, or amikacin. Pathologic pyuria (greater than 10 WBC/high-power field) supports the clinical impression of acute symptomatic bacterial pyelonephritis. However, many factors can spuriously lower the number of bacteria in the urine: prior diuresis or antimicrobials; obstruction distal to the site of infection; and infection not directly accessible to the collecting system.

Clinical studies of aztreonam (AZT) were performed in 10 pediatric cases. One transient pyuria case with 10(3)/ml E. faecalis detected in urine was excluded from clinical evaluation, because the presence of infection was unclear. Results were as follows: AZT was effective on 1 patient with meningitis (causative organism: H. influenzae), who was treated with 41.7 mg/kg 4 times a day. Results of administration of 58.1-78.9 mg/kg 3 or 4 times a day by intravenous injection for 1 E. coli sepsis-and-pyelonephritis complication case and 7 pyelonephritis cases (causative organisms: E. coli in 1, E. coli + E. faecalis in 1, E. faecalis in 1, P. aeruginosa in 3 and unknown in 1) were excellent in 4, good in 2 and poor in 2 cases. The pathogens of the 2 poor cases were E. faecalis and P. aeruginosa, respectively. Six of the pyelonephritis cases had vesicoureteral refluxes as an underlying condition. Clinical and microbiological effects of AZT were considered to be closely correlated with its MIC values. No side effect was recognized. Though abnormal laboratory findings were obtained in 4 cases, including elevations of GOT X GPT in 2 cases, GPT elevation in 1 case and plateletcount increase in 1 case. All of these abnormalities were minor and transient. The serum concentrations of AZT for a two-month-old patient with pyelonephritis were 65, 50, 35, 22.8 and 12.4 micrograms/ml at 1/2, 1, 2, 4 and 6 hours, respectively and T1/2 was 2.42 hours after injecting AZT 20 mg/kg by intravenous injection.(ABSTRACT TRUNCATED AT 250 WORDS)

THE REASONS FOR THE RECURRENCE OF URINARY TRACT INFECTION AFTER ANTIBIOTIC THERAPY ARE: (1) underlying renal disease, (2) the short female urethra, and (3) bacterial resistance. Quantitative bacteriuria rather than pyuria is important in diagnosis. Radiologic changes are late manifestations of pyelonephritis. Treatment of lower urinary tract infection requires a high urinary drug level, whereas renal infection requires high tissue levels. Urinary pH adjustment increases antibiotic effectiveness. Therapy for recurrent infection should be continued for at least six months.
