Acquired nonobstructive urinary bladder diverticulum: A case report

Abstract

Introduction: Urinary bladder diverticula are frequently resulting from obstructions. Our literature review did not reveal any cases of acquired urinary bladder diverticulum caused by long-term transurethral catheterization. Case Presentation: We report a rare case of a nonobstructive big urinary bladder diverticulum developed after a long-term urethral catheterization in a 62-year old male diabetic patient with normal subvesical urinary tract. The diverticulum was demonstrated by ultrasonography. Its formation was associated with the decubital changes of the bladder wall when the Foley catheter stayed for a longer period. Conclusion: Ultrasonographic examination of the urinary bladder is necessary to exclude such complication after a long-lasting catheterization as well as to maximally restrict the catheter's stay in the urinary bladder. © 2009 Yovchevski and Kostov; licensee BioMed Central Ltd.
