“…Investigators have concluded that samples positive for pyuria should be cultured to confirm a UTI. 12 , 13 Oikonomou and Alhaddad 14 reported that there was no association between pyuria and fever, sepsis in hemodialysis-dependent ESRD patients, urinalysis was not a reliable diagnostic tool in febrile and/or septic hemodialysis-dependent ESRD patients, and a urine culture was needed. Our study revealed that the positive predictive value of pyuria screening for UTI was 45.6% (26/57).…”

Introduction The aim of this study was to analyze urinalysis findings and urinary bacterial culture in hemodialysis-dependent end-stage renal disease patients. The research goal was to understand the proportion, risk factors, and the causative organisms of urinary tract infection in hemodialysis-dependent end-stage renal disease patients. Materials and Methods Between May 2020 and June 2021, this study included 100 hemodialysis-dependent end-stage renal disease patients (50 male patients and 50 female patients). The urine underwent microscopic examination, pyuria was defined as ≥5 white blood cells per high-power field, and urinary bacterial cultures were conducted for patients with pyuria. Bacteriuria was defined as ≥10 4 colony-forming units/mL in men and ≥10 5 colony-forming units/mL in women. Daily urine output was investigated by oral listening. Postvoiding residual urine volume was measured. Results Fifty-six percent of male patients and 30% of female patients had normosthenuria, 24% of male patients and 38% of female patients had pyuria, and 20% of male patients and 32% of female patients had a urinary tract infection. A comparison of normosthenuria and urinary tract infection revealed no statistically significant difference in age, time on dialysis, daily urine output, and postvoiding residual urine volume. The proportion of female patients among those with normosthenuria was 34.8%, whereas the proportion of female patients among those with UTI was 61.5%. Urinary bacterial cultures showed that the major causative organisms were Escherichia coli (45%; 18/40 cultures) and extended spectrum beta-lactamase-producing Escherichia coli (17.5%; 7/40 cultures). Conclusion The incidence of urinary tract infection was higher in female patients than in male patients. The proportion of resistant bacteria as the causative organisms was high in hemodialysis-dependent end-stage renal disease patients. Urinary bacterial culture should be checked while patients are able to void urine.
