Staghorn özellikte dev üreter taşı

Geyik boynuzu (staghorn) şeklindeki taşlar, böbrek içinde görülebilen taşlardır. Böbrek fonksiyonlarını, oluşum ve büyüme süreleri boyunca kendilerinin oluşumunu engelleyecek dereceye kadar bozmayan ve zaman içinde toplayıcı sistemin şeklini alarak büyüyen taşlar bu gruptandır.Sol üreterinde 54 x 24 mm dev boyutlara ulaşmış staghorn şeklinde bir taş bulunan olgumuzu, direkt üriner sistem (DÜS) radyografisi, intravenöz pyelografi (İVP), retrograd pyelografi ve ultrasonografi (US) bulgularıyla sunmayı amaçladık.

Staghorn like giant uretral stone

Staghorn stones are urinary stones that have the possibility to disturb the normal kidney physiology, though they do not reduce the renal functions to such a level that will prevent their formation, at least during the course of their progression. During the formation process, staghorn stones take the shape of renal pelvicaliceal system. Staghorn stones may develop in kidney in pathologic conditions, but it is unusual to find a staghorn shaped stone in the other parts of the urinary system. In literature, a urinary staghorn stone in extrarenal location was reported in a bifid ureter and called as giant ureteral staghorn stone.We report a case of a huge, staghorn like, left ureteral stone measuring 54 x 24 mm, with abdominal radiography, intravenous pyelography, retrograd pyelography and ultrasonography findings.
