A Case of Bilateral Renal Cancer in a Dialysis Patient With Enlarged ACDK Treated With Staged Laparoscopic Nephrectomy

Introduction End‐stage renal disease (ESRD) patients have a high risk of Acquired Cystic Disease‐associated Renal Cell Carcinoma (ACD‐RCC) due to chronic inflammation and cystic renal atrophy. Although laparoscopic radical nephrectomy (LRN) is standard, massively enlarged kidneys may increase surgical difficulty. Case Presentation We describe a long‐term dialysis patient with bilateral ACD‐RCC. Each kidney weighed over 1200 g. Despite the extreme size and cystic architecture, LRN was completed without conversion, transfusion, or major postoperative complications. Conclusion This case demonstrates that LRN can be safely and effectively performed in ESRD patients even when ACD‐RCC involves unusually large kidneys.
