Insertion of an internal-external nephroureteral stent during pediatric laparoscopic pyeloplasty: description of the technique.
Urology 2008 June
OBJECTIVES: We present a technique for inserting an internal-external nephroureteral antegrade stent during a laparoscopic pyeloplasty.
METHODS: We describe the step-by-step technique for external-internal stent insertion during transperitoneal laparoscopic pyeloplasty: (1) Before completion of the ueretopelvic junction anastomosis, a 14-gauge angiocatheter is inserted and the external-internal stent is advanced under direct vision downward into the ureter. (2) A percutaneous access to the intrarenal collecting system is then performed by using another 14-gauge angiocatheter. (3) Once in the pelvis, a 1.9F stone basket is passed through the angiocath and the proximal arm of the stent is brought out through skin.
CONCLUSIONS: The key advantage of this internal-external stent is that it can be removed in the clinic, thus not exposing the patient to another general anesthetic or cystoscopy for removal.
