title: Extensive, obstructing sodium urate deposition on wall of isolated ileum for replacement of entire ureter.
abstract: We report a rare case of obstructing sodium urate stones occurring in the form of extensive deposition on the wall of isolated ileum for replacement of the entire ureter. The stones were disintegrated and removed with a rigid ureteroscope and an electrohydraulic lithotriptor. Hyperuriaciduria, excessive alkalization of urine and urinary stagnation due to reflux, mucous retention, and prostatic hyperplasia were considered as the etiologic factors in the stone formation.
