Study design: Single case report.
Objective: To report a case of urethral obstruction because of calculus in a subject with spinal cord injury (SCI).
Setting: Bangalore, India.
Case report: A 25-year-old man sustained complete SCI at C(6) level following a road traffic accident. After 14 months, while on self-intermittent catheterization he noticed difficulty in introducing catheter and acute retention of urine. X-ray examination revealed a calculus in the penile urethra at the level of the glans penis.
Conclusion: Impaction of calculi in penile urethra, although rare, can manifest with acute painless urinary retention in patients with SCI.
