Clinical profile and predisposing factors for the development of urinary tract infection during the first 3 months postrenal transplantation: A tertiary care hospital experience

Abstract

Background: Infections in renal allograft recipients, especially urinary tract infections (UTI), are an essential factor leading to an increase in morbidity, graft failure, and degrading the health-related quality of life. Aims and Objectives: Our objective is to assess the causes, risk factors, microbiological profile, and antibiotic sensitivity pattern of UTI in renal transplant recipients. Material and Methods: It was a prospective observational study, conducted at the Department of Nephrology, Sir Gangaram Hospital, New Delhi, India. Three hundred ten renal transplant recipients were enrolled. Results: Out of 300 transplant recipients, 107 (35.6%) had UTI. The mean age of patients with UTI was 32 ± 10.5 years. Females have a higher incidence of UTI than males. 64.5% of all diabetic patients had UTI. Escherichia coli (41%) was the most common causative agent. Gram-negative bacilli attributed the majority (88.5%) of cases. Klebsiella pneumonia was found to be multidrug-resistant in most cases. 61% of patients with reflux kidney disease before transplant suffered from UTI. Conclusion: On multivariate analysis in our study, diabetes (P=0.01), prolonged urethral catheterization (p=0.002), and double J stent kept in situ (p=0.03) and reflux kidney disease before transplant (p < 0.02) were independently associated with UTI prolonged.
