The aim of this study was to evaluate the effect of two types of suprapubic ureteric stents on the number of urological complications after kidney transplantation.

Data were retrospectively collected from 366 consecutive kidney transplantations performed between January 2013 and January 2015 in our hospital, in which a suprapubic externalized ureteral stent was placed during surgery. Urological complications were defined as urinary leakage or ureteral stenosis requiring PCN placement.

A total of 197 patients received a straight stent with two larger side holes, introduced without a guidewire (type A ;8 Fr ‘Covidien’ tube) and 169 patients received a single J stent with 7 smaller side holes introduced with a guidewire ‘(type B;7 Fr ‘Teleflex’ single J stent). We found a significant higher incidence of PCN placements in type A stenting: 34 (17%) PCN interventions versus 16 (9%) in type B stenting (p= 0.030). No significant difference was found between the indications for PCN placement in both groups (p= 0.423). Stent dysfunction and early removal (< 8 days) was equally distributed in both groups (p= 0.397) while incidence of rejection and urinary tract infection (UTI) were higher in type B stenting. Patient and graft survival did not differ between the groups.

In conclusion, ‘stent type B’ is associated with less urological complications compared to ‘stent type A’. The type of stent does not affect patient and graft survival.
