[Xanthogranulomatous pyelonephritis associated with pregnancy, in ex-transplant donor with single kidney]. / Pielonefritis Xantogranulomatosa asociada a embarazo, en riñón único de antigua donante para trasplante.

We present the first case, up to our knowledge, of XGP in pregnant woman, in solitary kidney (related living kidney donor). Therapeutic abortion was not resolutive and nephron sparing surgery (espeleostomy) was successfully performed. Fourteen years later the renal function is still normal and 2/3 of renal parenchima are preserved. Literature review is pointed out.

[Ureteral complications of retroperitoneal prosthetic vascular surgery]. / Complicaciones ureterales de la cirugía vascular protésica retroperitoneal.

OBJECTIVE: Ureteral obstruction following retroperitoneal vascular by-pass has rarely been reported in the international world literature (only 169 cases). That's why we present three new cases to contribute at best knowledge of this iatrogenic disease. MATERIAL AND METHOD: Our cases were diagnosed by symptoms (number 2 and 3) and incidentally (number 1). The case 3 is exceptional because only 6 cases were previously described. RESULTS: Three different treatments were applied in our cases. The urinary fistula resulted into nephrectomy and the others were treated by endourological and reconstructive methods. We noted that the added comorbidity factors in all these cases make the pronogstic hazardous.
