Extended double-J ureteral stent

Continent forms of urinary diversion using intestinal segments are becoming increasinglycommon. As this new treatment modality evolves, our instruments and mechanical devices are likewise evolving and adapting to the changing needs placed on them. We have used a new type of double-pigtail ureteral catheter in patients requiring continent urinary diversion. It allows stenting of the ureteral-intestinal anastomosis and safeguards against urinary leak or extravasation; at the same time the catheter is accessible to the outside for easy replacement, manipulation, and radiographic evaluation. The catheter has also shown to be useful for other purposes such as uretero-neo-cystostomy. This is particularly important in the pediatric population where repeated cysstoscopy for stent removal or manipulation can be a significant drawback.
