Graft Survival in Patients With Polycystic Kidney Disease With Nephrectomy of Native Kidney Pretransplant.

Introduction: Autosomal-dominant polycystic disease (ADPKD) represents 5%-10% of cases of end-stage renal failure. However, management of these patients in terms of whether or not to perform a transplant and optimal timing remains controversial. The objective of our analysis was to evaluate graft survival in patients with ADPKD in which we conduct pretransplant nephrectomy.
Methods: This retrospective study including renal transplant patients secondary to ADPKD in our hospital between January 2000 and December 2012. Pretransplant native kidney nephrectomy was indicated in cases of need for space or repeated complications (cysts). We compared the initial function and graft survival between groups of transplanted based on whether nephrectomy had been performed or not.
Results: Eighty-seven patients underwent a kidney transplant owing to ADPKD; 62% (n = 54) were male, with an average age of 55.22 years. Twenty-seven patients (30%) underwent nephrectomy native kidneys before transplantation. There were no serious postoperative complications. Patients who underwent nephrectomy (group 1) showed values of creatinine of 1.57 and 1.50 mg/dL at 3 and 6 months, respectively. In the no nephrectomy group, these values were 2.03 and 1.83 mg/dL, respectively. Graft survival after the first year was of 98% for group 1 and 95% for group 2. The 5-year implant survival was 95% and 80%, respectively.
Conclusions: Native kidney nephrectomy before transplantation in ADPKD is safe in an experienced center, both in terms of surgery-related morbidity and mortality and graft survival and function.
