Acquired cystic kidney disease.

Area of Science:

• Nephrology
• Oncology
• Radiology

Background:

• Acquired cystic kidney disease (ACKD), or acquired renal cystic disease (ARCD), is a condition affecting patients with end-stage renal disease, often developing during chronic renal failure or after dialysis initiation.
• The development of ACKD is associated with sustained uremia, and its prevalence increases with the duration of dialysis treatment.
• The influence of immunosuppression, particularly in kidney transplant recipients, on ACKD development requires further investigation.

Purpose of the Study:

• To review the current understanding of the pathophysiology of acquired cystic kidney disease.
• To discuss the implications of ACKD for medical imaging.
• To highlight the association between ACKD and increased cancer risk.

Main Methods:

• Literature review of existing studies on acquired cystic kidney disease.
• Analysis of the relationship between dialysis duration, cyst presence, and cancer risk.
• Synthesis of current knowledge on ACKD pathophysiology and imaging.

Main Results:

• ACKD prevalence correlates directly with dialysis duration.
• The presence of cysts in ACKD is linked to an elevated risk of cancer.
• Pathophysiological mechanisms and imaging findings of ACKD are discussed.

Conclusions:

• ACKD is a significant complication in patients with end-stage renal disease.
• The duration of dialysis and the presence of renal cysts are key factors in ACKD.
• Further research is needed to fully understand ACKD's pathophysiology and its impact on cancer risk and imaging.
