Comparison of complications and short term results of conventional technique versus new technique during graft ureteral stent insertion in bari technique at Emam Khomeini Hospital, Urmia.

INTRODUCTION

There is debate on renal graft stenting during ureteroneocystostomy, patients with ureteral stents may encounter several complications such as encrustation, stent crustation which can lead to loss of kidney, and complications related to stent extraction: pain and UTI increasing related to cystoscopy for stent extraction accompanying excess expenses. This study designed to reduce complications related to stent extraction.

MATERIALS &

METHODS

90 patients prepared for renal transplantation during 1 year randomly classified to groups, study group: patients with attached stent to Foley catheter, control group: patients with conventional technique (stent separated from Foley) then in their follow up; UTI, stent crustation, luts severity compared to each other.

RESULTS

Second week and fourth week UTI reported 25.6%, 2.3% in study group versus 34.9%, 4.7% in control group (P.value:0.48 and 0.5). Urinary leakage was 3.3% overall, that all of them occurred in separate stent group, 37.5% vs. 0% in the linked stent group. Stent crustation in separate stent was 25% compared with 0% in the linked stent.

CONCLUSION

Low complications rate in linked stent group, despite the lack of significant statistical differences, but indicate the effectiveness and success of the new technique.
