Early post-transplant urinary tract infection epidemiology and risk factor

Abstract

Background and objectives: Renal Transplantation became the most successful management for end stage renal failure; postoperative urinary tract infection is the most common complication. The aim is to evaluate the outcome and risk factors of posttransplant urinary tract infection. Methods: This is a prospective study for renal transplant patients between 2018-2019 in Hawler/ Rizgary and Paky hospital. Patients, who underwent renal transplant, with 1 year follow up. Variable risk factors assessment done including chronic renal failure etiology, preoperative dialysis duration, operation time, length of drain and Foley’s catheter, type of immune suppressive therapy used, time and numbers of hospitalization associated with posttransplant urinary tract infection were examined, the relation between the risk factors and urinary tract infection was evaluated. Results: Total of 63 patients was involved, 12 had a total of 24 urinary tract infection attacks; the most common isolated microorganisms were E-coli and Klepsiella. The infection frequently appeared during the first 120 days postoperatively. Among the analyzed variables, there was no significant difference. Assessing all the variables, number of hospitalization after discharge were significantly more frequent in the 12 patients with infection attacks, although 31 patients out of 63 had hospitalized, as compared to patients without infection, but this difference was statistically insignificant. Conclusions: The most significant period for infection in renal transplanted patients after 1 year follow up is the first 4 months postoperatively. Patients who were admitted to hospital for different reasons and those who had preoperative history of urinary tract infection, have a higher risk.
