Ureteropelvic obstruction due to urinary calculi in transplanted kidney.

In chronic renal failure patients many factors may predispose to stone formation following renal transplantation. Urinary calculi occur in transplanted cases in 0.3 to 6.3%. ESWL, percutaneous nephrolithotomy or open surgical treatment is usually necessary to treat these patients. In this study we present a patient transplanted from a living donor at our centre. Stone formation developed 3 months after the operation and ureteropelvic obstruction was corrected by open surgical intervention.
