Successful Renal Transplantation in Patients with Polycystic Kidneys after Renal Contraction by Renal Artery Embolization: Report on 2 Cases / 대한이식학회지

ABSTRACT

Autosomal polycystic kidney disease is responsible for about 10% of the cases of end stage renal disease. The increase in kidney size is usually proportional to the degree of deterioration in renal function. At the time of transplantation, these nonfunctional kidneys can be massively enlarged and nephrectomy is required before renal transplantation. However, pretransplantation nephrectomy of polycystic kidneys has the potential risk of surgical complications, including ileus, hernias, infection, excessive bleeding and/or intestinal injury. We report here on two cases successful renal transplantation in patients with polycystic kidneys after renal contraction by renal artery embolization and without nephrectomy. The volume reduction was evaluated by CT before and 3 months after renal artery embolization and the reduction in volume was 48% and 44% in each case, respectively. The embolization was well tolerated in both cases without immediate or delayed complications except for fever and lumbar flank pain. Four months after renal artery embolization, both of the patients successfully received a transplant from living donors.
