Introduction

• Cause: rare sequela to chronic low grade urethral obstruction Urethra: obstruction and tenesmus.
• Bladder mucosa herniates through muscularis.
• Signs: dysuria, hematuria, asymptomatic.
• Diagnosis: positive contrast cystography Radiography: cystography.
• Treatment: affected areas should be excised surgically if associated with a clinical problem.

• Low grade urethral obstruction → tenesmus → herniation of mucosa.
