[Internal urinary drainage by double J stent in pediatric urology]

We used double pigtail ureteral stent in 16 children (aged 15 days to 13 years old). Indications included: pyeloplasty (12 cases with 2 anastomotic leakages and 1 acute postoperative renal retention), renal trauma (1 case), difficult ureterocystoneostomy (1 case), urinary ascites (1 case), and abdominal tumor compression (1 case). This drainage procedure provides a useful alternative to an external tube diversion (standard ureteral stent or nephrostomy). In pediatric urology, the double pigtail stent offers the advantages of exceptional patient tolerance, drainage security and efficiency, and short hospital stay. In our experience, stents were removed in an outpatient basis under general anesthesia but non endoscopic removal will be possible when smaller magnetic retrievers become available in urologic armamentarium.
