The hickman peel-away sheath: Alternative for pediatric percutaneous nephrolithotomy

Percutaneous nephrolithotomy presents a therapeutic challenge in children because of the disproportion between the sizes of the instruments and the kidneys, A technique for pediatric nephrolithotomy used on a 2-year-old female child is presented, The patient was born prematurely and developed kidney stones as a complication of furosemide therapy, She failed medical management with hydrochlorothiazide, and the stone did not disintegrate following extracorporeal shockwave lithotripsy (ESWL). A Chiba needle was used to access the renal collecting system percutaneously, Using a guidewire, sequential dilatation was performed to 16F. A 15F Hickman catheter introduction kit was then used, and the sheath was partially peeled away, A 10F pediatric cystoscope and grasper were inserted through the sheath to remove the stones. A 12F catheter was then placed through the sheath; the sheath was peeled away, and the catheter was left indwelling for 48 hours. No complications ensued, A postoperative nephrostogram showed free drainage and absence of residual stones, Utilization of the Hickman peel-away sheath constitutes an excellent alternative nephrolithotomy technique for children with stones unresponsive to more conservative treatment.
