Ureteral stent encrustation

Abstract

尿管狭窄に対するステントカテーテルの留置は腎機能の保全に有効である.とくに, 悪性腫瘍にともなう尿路閉塞症例では外科的尿路変更術の代用法として十分にその機能を示す, ステントカテーテル留置中に問題がないわけではない.合併症, 副作用の中で3例のステントカテーテル閉塞は感染および出血によるものであった

Palliative ureteral stent placement is effective in relieving obstructive renal impairment, especially that precedent to malignant spreading, and can take the place of surgical intervention. Furthermore, cutaneous antegrade and/or endoscopic retrograde stenting can be indicated for other pyelo-ureteric operations and prevent their complications, but is has its consequences: We experienced three cases in which stenting had to be repeated because of its obstruction. The stent catheter blockage is discussed.
