Native Nephrectomy in Patients With Autosomal Dominant Polycystic Kidney Disease Evaluated for Kidney Transplantation

Native nephrectomy (NN) in patients with autosomal dominant polycystic kidney disease (ADPKD) is indicated in cases of recurrent urinary tract infections and hematuria, neoplastic degeneration, and encumbrance. Timing, indication, and surgical approach of NN depends on the symptoms or policy of the center. The aim of our study is to evaluate our experience. In our retrospective study, we included 130 patients with a diagnosis of ADPKD from 530 patients evaluated for renal transplantation from 2011 to 2017. We analyzed the etiologic indication, the timing, and the complications of NN. In our cohort, 53 patients underwent open NN, 85% pre-kidney transplantation (KT), 13% post-KT, and only 1 case simultaneous with KT. In the pre-KT group, indications included: major indication was encumbrance in the. In the post-KT group, the major indication was infection followed by encumbrance, which developed after KT. Complications were: 3 cases of bleeding (1 required relaparotomy, 2 evolved into hematoma and radiological derange); 1 iatrogenic iliac artery injury, which was contextually repaired, and 5 cases of incisional hernia. At 35 +/- 7.2 months follow-up, patients' survival was 96%; 1 patient died at the induction of anesthesia and 1 patient from sepsis after double NN and removal of nonfunctional transplanted kidney. NN is not without complications and should be performed when clearly indicated. In our experience, we preferred to perform NN before KT.
