Time series: pathologic determinants of cytobiochemical urinalysis and urinary infections at the University Clinics in Kinshasa

cytobiochemical analysis of urine samples is the most requested complementary laboratory tool along with blood count. It has high predictive value in patients with urinary tract infections when it is properly done and scrupulously interpreted. The purpose of this study was to assess the rate, progression, determinants and cytobiochemical comorbidities of urinary tract infections. we conducted a documentary, descriptive, analytical and comparative study of patients referred for cytobiochemical examinations of urine to the laboratories of the University Clinics in Kinshasa (UCK) between 2011 and 2014. a total of 8926 cytobiochemical tests were requested, with less than 2% of biochemical tests. The study involved more women than men (6426 women vs 2500 men), with a sex ratio of 3F: 1M. Cytobiochemical tests were more requested in the 30-39-year age group (17%; n=1517) mand during the rainy seasons 72% (n=3511), with a peak in May. Urinary tract infections accounted for 54,8% [adjusted estimates n=4892 including E. coli (n=1937), Klebsiella (n=993)] and were mainly diagnosed over the period 2012-2014. There was an independent and significant association between female sex (adjusted OR = 3.5; CI = 95%; 3.1-3.8; P
