Organ-sparing treatment of kidney cancer in the context of autosomal dominant polycystic kidney disease

Autosomal dominant polycystic kidney disease is the most common hereditary kidney disease, but the combination of this pathology with renal cell carcinoma is a rare clinical observation. The main treatment method in this situation is nephrectomy. The article presents a clinical case of a 69-year-old patient diagnosed with left kidney cancer pT1bN0M0, stage I with autosomal dominant polycystic kidney disease and chronic kidney disease. Due to severe concomitant kidney pathology, the patient underwent organ-preserving surgery in November of 2024 which included resection of the left kidney with fenestration and excision of renal cysts. The early and late postoperative periods were uneventful with preservation of renal function.
