RESUMEN
As the routine use of ureteral stents [US] remain controversial. A recent met-analysis of ureteral stenting concluded that the routine use of US resulted in improved outcomes. In contrast, the indiscriminate use of US can lead to adverse complications. To better define this question, we reviewed our single center experience in which US were placed selectively. 301 patients were eligible to be enrolled. 55 living donor and 246 deceased-donor charts were analyzed for donor and recipient clinical characteristics, immunosuppressive therapy and outcomes. 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 urinary leaks, 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 urinary leaks included dual and en-bloc pediatric donor kidney transplants, extended criteria donors and the use of single U stitch technique for ureteral anastomoses. Our results demonstrate that the majority of patients can be successfully transplanted without the routine use of US. Selective use of US should be reserved for high-risk situations
