Objective:

To report a unique case of urinary obstruction caused by a chicken bone in an elderly patient.

Approach:

• Intervention: After conservative antibiotic management failed, an antegrade nephroureteric stent was placed, relieving the obstruction.

Key Findings:

• The chicken bone caused severe hydroureteronephrosis and renal parenchymal atrophy.
• This case represents the first reported instance of obstructive uropathy due to an ingested foreign body.

Interpretation:

The case illustrates the potential for unusual causes of urinary obstruction in elderly patients.

Limitations:

• The prior CT findings from 3 years earlier did not identify the chicken bone as the cause of obstruction.

Conclusion:

The case highlights the importance of considering atypical causes of urinary obstruction.
