[Urinary lithiasis after renal transplantation. 9 cases (author's transl)].

Nine cases of urinary lithiasis following renal transplantation are reported. They differ from 15 cases in the literature in their development late after transplantation and in that no relation with hyperparathyroidism could be clearly demonstrated. We emphasise the difficulty of the clinical and radiological diagnosis of this little-known complication. The course is essentially similar to that in non-transplant patients with lithiasis.
