Percutaneous (Endo) Infundibulotomy

Abstract
Infundibular stenosis often results in hydrocalix and caliceal diverticulum and stone formation. If not corrected, stenosis will lead to deterioration of the renal parenchyma. Percutaneous infundibulotomies through a nephrostomy tract were successful in 14 patients. Direct puncture into the involved calix provides the best access for stone removal and incision or dilatation of the infundibular stenosis.
