Endoscopic removal of staghorn calculi in patient with high urinary diversion

The treatment of recurrent renal calculi in patients after ureteroileal urinary diversion is difficult, especially when urinary stones are formed in the presence of urinary tract infection. In many cases, these patients already have undergone multiple renal operations and more surgery could pose difficult technical problems. We report on a patient with a high urinary diversion in whom bilateral staghorn renal calculi developed, and then were endoscopically removed. The conversion of ureteroileocutaneous diversion to a high pyeloileocutaneous diversion is recommended in selected cases as alternate treatment for patients with recurrent stone formation.
