The use of a dipstick to detect leucocyte esteraseuria (Chemstrip L) was compared with the visualisation of leucocytes in a Gram stained smear for the detection of pyuria. The sensitivity and specificity of the two systems using the predictive value theory were similar. The use of a dual screening procedure (automation plus dipstick) allowed reliable 4 h screening of urine specimens for the det...

DURING the last few years attention has been focussed largely on streptococcal infections in the puerperium. I wish to discuss infections with coliform organisms, with special reference to the urinary tract, for although much less serious they are very common and contribute largely to puerperal morbidity. I use the term " pyuria " to mean the presence of both pus cells and organisms in the urin...

A review of rapid urine screens for detection of bacteriuria and pyuria demonstrates a number of available alternatives to the culture method. Selection of one or more of these systems for routine use is dependent upon the laboratory and the patient population being tested. The laboratory approach to the diagnosis of urinary tract infection should consider the clinical diagnosis of the patient ...

Urinary tract infection is a serious problem in diabetic patients, and asymptomatic bacteriuria (ASB) in these patients is a risk factor for pyelonephritis and renal dysfunction. In the present study, we investigated the relationships between age, body mass index, duration of diabetes, HbA1c level, glucosuria, glomerular filtration rate and microalbuminuria in type 2 diabetic patients with ASB....

An 82-year-old female patient presented with fever and chills of two weeks’ duration. Because of pyuria on dipstick, sulfamethoxazole and trimethoprim had been empirically initiated. On admission, temperature was 38.5◦C. Blood tests showed increased C-reactive protein and creatinine serum levels (Figure A). White blood cell count was normal. Urinalysis confirmed leucocyturia (350/hpf) but urine...
