Kidney Injury due to Ureteral Obstruction Caused by Compression from Infected Simple Hepatic Cyst

Area of Science:

• Hepatology
• Urology
• Radiology

Background:

• Simple hepatic cysts are common, usually asymptomatic.
• Symptomatic complications include hemorrhage, rupture, and infection.
• Urinary tract obstruction from hepatic cysts is exceptionally rare.

Observation:

• An 82-year-old male with a history of nephrectomy presented with an infected giant hepatic cyst.
• The cyst caused right hydronephrosis due to ureteral compression.
• The patient had impaired renal function.

Findings:

• Ultrasound-guided percutaneous drainage and minocycline sclerotherapy were performed.
• Successful treatment led to cyst regression.
• Right hydronephrosis resolved, and renal function improved.

Implications:

• This is the first reported case of hydronephrosis caused by ureteral obstruction from a hepatic cyst.
• Highlights the importance of considering hepatic cysts in the differential diagnosis of obstructive uropathy.
• Demonstrates the efficacy of percutaneous management for complex hepatic cysts.
