Infective complications associated with ureteral stents in renal transplant recipients.
OBJECTIVE
Stenting of the ureter is commonly performed during renal transplantation to avoid early complications. However, it predisposes to infections that may pose a significant threat to the graft and patient. Our study sought to investigate the incidence of infections associated with stents in renal transplant recipients.


METHODS
A retrospective analysis of 100 consecutive renal transplant recipients performed over 1 year with 6 months follow-up.


RESULTS
The median recipient age was 46 years (range, 19-71 years). Among the study group, 75 patients received an organ from deceased donor and 25 from live donor. In our study, there were 79 patients with a stent (ST) and 18 without a stent (WOST); 3 patients who required nephrectomy were excluded from the study. There were 2 ureteric stenoses that occurred following stent removal: 1 required surgical correction and 1 was treated radiologically. There were no cases of urinary leak. The incidence of urinary tract infection (UTI) was significantly greater among ST compared with WOST subjects (71% vs 39%; P = .02). New episodes of UTI following removal of the stent were more common among patients who had experienced infections while having a stent compared with infection-free stented patients (54% vs 30%; P = .04).


CONCLUSIONS
A ureteric stent may help to reduce early postoperative complications (leak and stricture), but increased the likelihood of UTI. Infection while having a ureteric stent was associated with a high recurrence rate of UTI even after stent removal.
