The relationship between Staphylococcus aureus bacteremia and bacteriuria was studied over a five year period in three hospitals. In a Veterans Administration Hospital, 59 patients with Staph, aureus bacteremia had a urine culture within 48 hours of a positive blood culture. In 16 of 59 (27 per cent), greater than 10(5) Staph. aureus was recovered from the urine in pure culture. Six of these patients had apparent primary staphylococcal urinary tract infection. Clinical and laboratory parameters in the patients with staphylococcal bacteremia and bacteriuria were compared with those in 31 patients with staphylococcal bacteremia and sterile urine cultures. The two groups differed only in the more frequent occurrence of pyuria and proteinuria in the bacteriuric patients. In two other hospitals, staphylococcal bacteriuria occurred in 7 per cent of patients with Staph. aureus bacteremia and in 13 per cent of cases of staphylococcal endocarditis. Review of autopsy records for 33 patients who died within one month of their bacteremia failed to show a correlation between bacteriuria and the presence of renal abscess. Staphylococcal bacteriuria is a frequent and unexplained concomitant of Staph. aureus bactremia.

A clinical epidemiological study was conducted to determine the association, if any, between the incidence of urinary schistosomiasis and urinary tract infection. The urinary excretion of protein and cells was also studied. Data was collected from 2 rural Nigerian communities--1 with a low level of endemic urinary schistosomiasis and the other with a high level. Midstream urine specimens were collected from the 2 populations. The laboratory procedures are described and the findings are presented in detailed tables. Proteinuria, haematuria, pyuria and bacteriuria were found to occur at significantly higher levels in the area of high than low schistosomiasis endemicity.

Pyuria, proteinuria and haematuria have been shown to be unreliable parameters for the diagnosis of bacteriuria in 171 children with 455 recurrences of chronic urinary tract infection. Bacteriuria caused haematuria in 5%, proteinuria in 18% and even pyuria in only 47% of all instances. Pyuria has been also found in 11% of sterile urines. The incidence of pyuria increases with the age of the children and depends on the type of the organisms, but the latter was true mainly in children with obstructive lesions of the urinary tract. Children with repeated proteinuria during follow-up tend to have a higher incidence of pathologic findings on the i.v.-pyelogram.

Twenty-eight patients with demonstrated chronic renal vein thrombosis were studied. In seven, only small venous channels were involved; in 21, both small and large veins were thrombosed. A constellation of findings occurred with such frequency in these patients that we believe it virtually diagnostic of renal venous obstruction. These findings include the nephrotic syndrome, great variability in proteinuria and glomerular filtration rate, pulmonary embolization, sterile pyuria, hematuria, hyperchloremic acidosis, decreased renal tubular threshold for glucose and increased fibrin degradation products. These findings are an indication for definitive angiographic and biopsy procedures. Prolonged anticoagulant therapy was generally very effective.

This autosomal dominant disorder usually appears in middle life. The most common findings are proteinuria, abdominal pain and palpable kidneys, followed by hematuria, hypertension, pyuria, uremia and calculi. In 15% of patients, death is due to cerebral aneurysm. Family counseling and the detection of "at risk" family members are important elements of management. Statistically, half of the offspring of one affected parent will have the disease.

Diagnostic criteria of analgesic nephropathy with well-defined sensitivity and specificity are not available. During a 2-year period all new patients (n = 273) starting renal replacement therapy in 13 Belgian dialysis units were investigated aiming to select diagnostic criteria of analgesic nephropathy with acceptable performance. Using several interview techniques, a history of analgesic abuse was found in 31% of the patients. Analgesic abusers presenting a clear non-analgesic-related renal diagnosis were excluded from analysis (n = 25). Comparing the remaining abusers (n = 60) and patients without a history of analgesic abuse (n = 188) it was found that renal imaging investigations (sonography plus tomography), showing a decrease in length combined with bumpy contours of both kidneys, presented a sensitivity of 90% and a specificity of 95%. The additional finding of signs of renal papillary necrosis resulted in an overall sensitivity of 72% and a specificity of 97%, giving a positive predictive value of 92%. Other signs frequently mentioned in the literature (hypertension, anaemia, sterile pyuria, bacteriuria, proteinuria) showed insufficient sensitivity and/or specificity to be of help for diagnosing analgesic nephropathy in end-stage renal failure (ESRF) patients starting renal replacement therapy.

We report a case diagnosed as bilateral ureteritis cystica by ureteroscopic examination. A 51-year-old female was admitted with pyuria and proteinuria. Retrograde pyelography revealed multiple, small, smooth and round punched-out defects in the bilateral lower ureters. Ureteroscopic examination and punch biopsy were performed with a suspected diagnosis of ureteritis cystica. The histological examination revealed chronic ureteritis. This patient was given conservative treatment (chemotherapy) and careful follow-up.

The diagnosis of urinary tract infections were established on fifty children in our hospital in the last year. Most of the patients were between the age of 1-12 month (28 cases, 56%). The ratio of female/male was 3.5. Fever was the most common symptom (17 cases, 34%). In the routine urinalysis, proteinuria and pyuria were revealed in 11 cases (22%), and 44 cases (88%), respectively. E. coli was the most common microorganism isolated from urine cultures (70%). Twenty-two patients were regularly followed up and recurrence was observed in 7 patients (32%).

A 17-year old-male presented with a 6-week history of weight loss, lassitude and calf pains. On examination he was very pale. Laboratory tests showed a very high erythrocyte sedimentation rate (155 mm in the first hour), anaemia (haemoglobin 10.1 g/dl), and a raised serum creatinine of 1.54 mg/dl. Microhaematuria (5-10 erythrocytes/microliter) and pronounced pyuria (500 leucocytes/microliter) were present, but the urine was sterile and there was no increase in albumin excretion. The serum IgG was raised to 75.7 g/l, suggesting an autoimmune disorder. Anti-nuclear antibodies (titre 1 : 1920) and anti-double-stranded DNA antibodies (31 U/ml) were present, while the serum complement C4 was decreased to 0.11 g/l. Renal histology showed an interstitial nephritis without glomerular involvement, while the bone marrow showed vasculitis accompanied by a prominent plasma-cell infiltrate. A diagnosis of interstitial nephritis associated with systemic lupus erythematosus was made, with asymptomatic cardiac and hepatic involvement. Renal function recovered rapidly with prednisolone therapy (initial dose 2 mg/kg.d). While glomerulonephritis is the most common lupus-associated renal disorder, isolated interstitial nephritis may occur in some cases, often with an absence of proteinuria.

One hundred and twenty six patients diagnosed as having AIDS had their urinalysis and electrolyte profiles studied. The commonest electrolyte abnormalities were a low serum bicarbonate in 56% of the patients and hyponatraemia in 48%. Possible aetiological factors are discussed. Significant pyuria was found in 10% of the patients and significant bacteriuria in 13%. Escherichia coli was the commonest isolated organism (56% of all the culture positive cases). Proteinuria above the upper limit of normal was detectable in 13% of the patients; of these, 25% had proteinuria in the nephrotic range. Of the patients 3% had clinical and biochemical evidence of renal insufficiency. It is concluded that significant bacteriuria occurs commonly in AIDS and that renal insufficiency and nephrotic syndrome may be associated with the disease. It is also noted that other electrolyte and acid-base abnormalities, in particular hyponatraemia and low bicarbonate levels may contribute to the morbidity and mortality in patients suffering from AIDS.
