Abstrakt: Surgical stapling devices to close the proximal end of the isolated loop of an ileal urinary conduit have been used since the early 1970s (Assadnia et al, 1972). However, the occasional development of calculi forming around the metal staples has deterred uniform acceptance of this technique in spite of its advantages of speed and decreased post-operative morbidity (Assadnia et al, 1972; Bergman et al, 1978).We describe two patients who presented to this hospital in recent months, in whom surgical staples migrated proximally into the renal pelvis, becoming the nidus for stone formation in one of the patients.
