Nephrectomy in patients with Caroli's and ADPKD may be associated with increased morbidity

Autosomal dominant polycystic kidney disease (ADPKD), characterized by multiple bilateral renal cysts, is the most common inherited disorder of the kidney and an important cause of end-stage renal disease (ESRD). Caroli's disease is a much less frequent condition with ectasia of the intrahepatic biliary system. A clear association between autosomal recessive and Caroli's disease has been described, but only 4 cases of ADPKD and Caroli's disease have been reported with 2 postoperative mortalities. The aim of this case is to increase the awareness of intra-operative and postoperative complications. A 66 year-old male was diagnosed with ADPKD and Caroli's disease with hepatosplenomegaly and 4 episodes of ascending cholangitis. After 3 years of hemodialysis for ESRD, he received a cadaveric renal allograft. Subsequently, he developed paroxysmal atrial fibrillation. Upon anticoagulation, he developed multiple episodes of gross hematuria from the left native kidney. After the anticoagulation therapy was discontinued, he underwent bilateral nephrectomies of his native kidneys. Intra-operatively, a splenic laceration could not be managed conservatively. Therefore, splenectomy was performed. In addition, he developed ascending cholangitis post-operatively that was treated with antibiotics. He was discharged on postoperative day 18. Genetic testing revealed that the patient is heterozygote for a large deletion in PKD1 gene, which encompasses all tested exons (exons 1-44).
