Laparoscopic ureterocalicostomy in children: The technique and feasibility.

Ureterocalicostomy is a salvage technique commonly used for failed pyeloplasties; it has also been reported as a primary procedure in ureteropelvic junction obstruction (UPJO). This video describes the technique of laparoscopic ureterocalicostomy for primary UPJO in a child with a malrotated kidney and parenchymal thinning. A 13-year-old girl with symptomatic UPJO was found to have a malrotated kidney with a high posterior insertion of the ureter. A laparoscopic dependent ureterocalicostomy over a double-J stent was performed. The postoperative course was uneventful, with excellent clinical and radiological outcomes. Literature review revealed only two reports of this laparoscopic procedure as a primary surgery in children (one with intrarenal pelvis associated to urolithiasis and the other with a malrotated kidney). Laparoscopic ureterocalicostomy is a safe and feasible option in selected cases with parenchymal thinning due to atypical UPJ anatomy or failed pyeloplasty. Published by Elsevier Ltd.
