| Summary: | Our objective was to determine incidence, predisposing factors, and microbiological profile of urinary tract infection (UTI) in renal transplant recipients in our center. This was cross-sectional observational study, conducted at the Department of Nephrology, Army Hospital Research and Referral, Delhi, India. Two hundred and ten renal transplant recipients were studied over one year. Out of 210 transplant recipients, 69 (32.86%) had UTI. Majority (59/69) had undergone live renal transplantation and 10 cases had received cadaveric grafts. Forty-nine patients had primary infection while 20 patients had recurrences. The mean age of patients with UTI was 38.63 ± 10 years. The incidence of UTI was higher in females (42.25%) than males (28.06%, P = 0.038). Majority of patients in younger age group (age <30 years) were female (58.82%). Males were predominantly affected in higher (>30 years) age group (61.54%). Most common causative agent was Escherichia coli (72.46%). Gram-negative bacilli accounted for 94.20% (65/69) while Gram-positive cocci for 5.8% (4/69) of positive cultures. Multidrug resistance was highest in Klebsiella pneumoniae (100%). Fifteen cases with UTI were detected to have underlying urinary tract abnormalities, most common being urethral stricture (60%). One patient was detected to have broken double J stent in the renal pelvis which led to recurrent E. coli infection. Forty-eight patients (69.57%) developed acute graft dysfunction secondary to UTI. Female sex (P = 0.038), urinary tract abnormality (P <0.01), prolonged Foley's catheterization (P <0.01), prolonged hospitalization after transplantation (P <0.01), new-onset diabetes after transplantation (P <0.01), and coexisting hepatitis C infection (P = 0.012) were statistically significant predisposing factors for UTI in renal transplant recipients.
