[A cause of acute renal dysfunction: a giant bladder diverticulum]

Area of Science:

• Nephrology
• Urology
• Gastroenterology

Background:

• A 77-year-old male presented with acute kidney injury (AKI) superimposed on chronic kidney disease (CKD).
• Symptoms included gastric discomfort, vague urinary issues, and suspected ascites.
• Initial assessment revealed abdominal effusion.

Observation:

• Abdominal ultrasound identified a giant urinary bladder diverticulum.
• The diverticulum was associated with bilateral hydronephrosis.
• Preserved diuresis was noted despite the significant findings.

Findings:

• Giant urinary bladder diverticulum as a rare cause of obstructive uropathy.
• Bilateral hydronephrosis secondary to bladder diverticulum.
• Diagnostic challenges in differentiating from other causes of ascites.

Implications:

• Highlights the importance of comprehensive diagnostic workup in AKI and CKD.
• Underscores the need to consider rare bladder pathologies.
• Informs the diagnostic and therapeutic strategies for managing giant bladder diverticula and their complications.
