Objective: Urolithiasis could be caused by urinary tract infection (UTI). UTI in patients with urolithiasis need to be diagnose and manage as soon as possible. This study was aim to determine the diagnostic value of urinalysis examination to diagnose urinary tract infection (UTI) in patients with urolithiasis.Material & method: This study was an observational analytic with cross sectional study design, comparing one diagnostic tool with the gold standard tool to diagnose UTI. Total samples collected were 186 patients at Sardjito General Hospital, Yogyakarta. Urine culture and urinalysis were performed in patients with urinalysis and UTI. The results of urine culture and urinalysis were then compared by 2x2 table.Results: The sensitivity results on leukocyte esterase, eritrocyturia, bacteriuria, and nitrite respectively were 82.7%, 57.14%, 37.59%, and 13.53%. The specificity results on nitrite, bacteriuria, eritrocyturia, and leukocyte esterase respectively were 63.26%, 56.60%, 50.94%, and 33.96%. The highest level of accuracy was leukocyte esterase with 68.81% accuracy.Conclusion: This study showed that leukocyte esterase had good sensitivity with an accuracy of 68.81%. Examination of nitrite had the highest specificity compared to the other variables in urinalysis examination.

Background: Determination of contributing factors for jaundice would result in better programming for prevention. This study was performed to determine the prevalence rate of Urinary Tract Infection (UTI) among neonates with jaundice admitted in Arash Hospital from October 2013 to October 2014. Methods: In this descriptive cross-sectional study, term neonates with non-hemolytic jaundice admitted in Arash Hospital from October 2013 to October 2014 were evaluated for UTI by urine culture and the data were recorded by checklist using medical documents. Results: A total of 436 term infants were enrolled in the study. Mean age at the time of admission was 6.03±3.355 days with age range of 3-18 days including 291(0.66%) males and 145(0.33%) females. Urine culture was positive in 32 neonates (7.3%).The most common germs were Klebsiella in 37.5%, Escherichia coli (E. coli) in 21.9%, Staphylococcus in 9.4%, Pseudomonas in 3.1%, Enterococcus in 15.6%, Enterobacter in 9.4%, and Group B Streptococcus (GBS) in 3.1%. Conclusion: Urine culture should be a part of routine clinical evaluation for all icteric neonates at the age of 5-6 days or more who have no risk factors to exclude the possibility of coincidental UTI.

Background Urinary tract infection (UTI) is the most commoncause of fever in children. Less frequent disposable diaper changingis thought to be a cause ofUTI in children. While wearing a diapei;the perinea! area becomes damp with urine allowing bacteria tomigrate from the anus to the external urethral orifice.Objective To assess for an association between the frequencyof disposable diaper changing and urinary tract infections inchildren.Methods This cross-sectional study was conducted in thechildren's outpatient clinic of Haji Adam Malik Hospital fromApril to June 2010. Urine culture was performed in children withsuspected UTI who wore disposable diapers every day. Subjects'ages ranged from 2 months to 2 years 6 months, with samplesmatched and collected by consecutive sampling. Diagnosis ofUTIwas based on urine cultures with bacterial count 2:: 105/mL. Eightychildren were followed in this study and divided into two groups:positive (n=40) and negative (n=40) urine cultures. Chi squaretest was use d to analyze the association between the frequency ofdaily disposable diapers changing during a one week period andthe urine culture results.Results The frequency of daily disposable diapers changing in80 subjects was as follows: < 4 times (22.5%), 4-5 times (40%),and 2::6 times (37.5%) . The frequency of daily disposable diaperchanging in children with positive urine culture was as fo llows:< 4 times (1 8 out of 40), 4-5 times (22 out of 40), and 2::6 times(O out of 40); (P < 0.0001). The most common bacterial speciesfound in urine cultures was Escherichia coli.Conclusion Lower frequency of daily disposable diaper changingis significantly associated with higher UTI incidence in children.

In young sexually active male patients, clinical differentiation between non-gonococcal urethritis (NGU) and urinary tract infection (UTI) can be difficult. UTI as a cause of NGU has been suggested before, but the prevalence of UTI among acute NGU patients has not been evaluated. We conducted a prospective cross-sectional study of 156 male patients with clinical features of acute urethritis. The prevalence of UTI among acute NGU patients was 6.4% (CI: 1.5–11.3%). There was a possible association between UTI and NGU but this was not statistically significant. The sensitivity and specificity for combining leucocyte esterase and nitrite tests were 83.3% and 89.8% respectively, with a negative predictive value of 98.8%. We conclude that a mid-stream urine specimen should routinely be collected in patients with symptoms of urethritis. This should be analysed by dipsticks incorporating nitrite and leucocyte esterase tests. Those with a positive dipstick should then be confirmed by culture.
