Embolization of renal arteries before transplantation in @entity1 with XXXX : a single institution long-term experience.

@entity1 @entity7971 @entity8 @entity887 @entity703
PURPOSE: We aimed to retrospectively assess the long-term safety and efficacy of embolization of renal arteries ( @entity7971 ) in @entity1 with @entity8 ( @entity8 ) before renal transplantation. MATERIAL AND METHODS: Between January 2008 and November 2013, 82 @entity7971 procedures were performed on 76 kidneys in 73 @entity1 (mean age 53 years, range: 34-72). All @entity1 had @entity703 and were under dialysis and on the renal transplant waiting list with a temporary contraindication due to excessive renal volume. RESULTS: @entity7971 was considered successful in 89.5% (68/76) of embolized kidneys, meaning that the temporary contraindication for transplantation could be withdrawn for 65 @entity1 (on average 5.6 months, range: 2.8-24.3, after @entity7971 ). Mean volume reduction was 40 (range: 2-69) at 3 months and 59% (35-86) thereafter (both p   <   0.001). @entity887 occurred after 15 of 82 procedures (18.3%). The severe complication rate was 4.9%. Forty-three (67.7%) transplantations were successfully conducted after @entity7971 , with a mean follow-up of 26.2 months (range: 1.8-59.5), and the estimated 5-year graft survival rate was 95.3% [95% CI: 82.7-98.8]. CONCLUSIONS: @entity7971 is a safe and effective alternative to nephrectomy before renal transplantation in @entity1 with @entity8 . KEY POINTS:     Embolization of non-functioning polycystic kidneys allowed transplantation in 89.5% of cases.     Technical failure rate was 7.9% after embolization, irrespective of the technique used.     @entity887 occurred after 18.3% of the procedures.     A low rate of severe complications (4.9%) was observed after renal embolization.
