| Popis: | Background: Despite significant advancements in renal transplantation, certain basic surgical practices suchas the routine use of ureteral stents (US) remain controversial. A recent met-analysis of ureteral stentingconcluded that the routine use of US resulted in improved outcomes. In contrast, the indiscriminate useof US can lead to adverse complications.Objective: To better define this question, we reviewed our single center experience in which US wereplaced selectively.Methods: 301 patients were eligible to be enrolled. 55 living donor and 246 deceased-donor charts wereanalyzed for donor and recipient clinical characteristics, immunosuppressive therapy and outcomes.Results: 28 US were placed for either small bladder capacity (n=7), unhealthy appearing bladder tissue(n=8) or for an uncertain vascular supply to the ureter (n=13). Patients with US did not develop urinaryleaks, 8 (28%) developed complications including obstruction, encrustation, and urinary tract infections.12 (4.3%) non-stented patients developed a clinically significant urinary leak. Risk factors for urinaryleaks included dual and en-bloc pediatric donor kidney transplants, extended criteria donors and the useof single U stitch technique for ureteral anastomoses.Conclusion: Our results demonstrate that the majority of patients can be successfully transplanted withoutthe routine use of US. Selective use of US should be reserved for high-risk situations. |
