Here, we assessed the diagnostic accuracy of fluorescence in situ hybridization (FISH) for detecting aggressive upper tract urothelial carcinoma (UTUC). A total of 210 UTUC patients from a single hospital in China were enrolled in this retrospective study between 2012 and 2016. Patients were classified as FISH-positive or -negative based on FISH analysis of voided urine, and the clinicpathologi...
BACKGROUND Up to half the residents of nursing homes for the elderly have asymptomatic bacteriuria (ABU), which should not be treated with antibiotics. A complementary test to discriminate between symptomatic urinary tract infections (UTI) and ABU is needed, as diagnostic uncertainty is likely to generate significant antibiotic overtreatment. Previous studies indicate that Interleukin-6 (IL-6) ...
The diagnosis of ASB is the most important step in managing ASB. As stated at the article the most important point for diagnosis is microbiological tests. In this context the number of specimens for culture is crucial. In guidelines ASB in men is defined as the isolation of ≥ 105 cfu/mL bacteria in a single cleancatch voided urine specimen. On the other hand in women, two consecutive urine spec...
Bladder cancer is diagnosed by cystoscopy, a costly and invasive procedure that is associated with patient discomfort. Analysis of tumor-specific markers in DNA from sediments of voided urine has the potential for non-invasive detection of bladder cancer; however, the sensitivity is limited by low fractions and small numbers of tumor cells exfoliated into the urine from low-grade tumors. The pu...
Reference ranges for -amylase in serum, spontaneously voided urine, and 24h urine were determined, using 4,6-ethylidene-(G7)-l-4-nitrophenyl-(Gl)-a,£)-malthoheptaoside äs the Substrate (EPS method), at 25, 30, and 37 °C. The measured values were evaluated with and without the use of a factor which converts the results of the -amylase EPS method into values comparable to those obtained with the ...
The pterins xanthopterin (2-amino-4:6-dihydroxypteridine) (Koschara, 1936) and biopterin (2amino 4 hydroxy-6-[1: 2-dihydroxypropyl (L-erythro)]-pteridine) (Patterson, Saltza & Stokstad, 1956) have been isolated from human urine. It has been suggested that the pterins 2-amino-4-hydroxypteridine-6-carboxylic acid, 2-amino-4-hydroxypteridine and isoxanthopterin (2-amino-4:7-dihydroxypteridine) are...
BACKGROUND The cause of acute uncomplicated cystitis is determined on the basis of cultures of voided midstream urine, but few data guide the interpretation of such results, especially when gram-positive bacteria grow. METHODS Women from 18 to 49 years of age with symptoms of cystitis provided specimens of midstream urine, after which we collected urine by means of a urethral catheter for cul...
