Renal stone in transplanted kidney is uncommon. Renal stone is seen in less than %1 of transplanted kidneys. In our hospital there were 400 renal transplantation in 9 years, of whome, 3 (%7) developed renal stone in transplanted kidney 3,2.5 and 1.5 years after transplantation. The stone was passed in first patient spontaneously. The renal stone of second patient was treated with ESWL. In third patient two sessions of ESWL was unsuccessful and the stone was treated with PNL. Stone in transplanted kidney can produce severe hydroureter and anuria in some cases. It may be few clinical symptom initially. We recommended non invasive procedures (hydration and ESWL) in stones of transplanted kidney.
PNL and open surgery are reserved for refratory cases.
