Large bladder diverticulum causing direct extrinsic compression of the left ureter.

Area of Science:

• Urology
• Anatomy

Background:

• Bladder diverticula are outpouchings of the bladder mucosa, often linked to bladder outlet obstruction.
• While typically asymptomatic, they can manifest as lower urinary tract symptoms, hematuria, or infections.

Observation:

• A 37-year-old male presented with left flank pain and hydronephrosis.
• This was caused by a large bladder diverticulum leading to extrinsic compression of the left ureter.
• The patient also had a high bladder neck, contributing to voiding dysfunction.

Findings:

• A bladder neck incision was performed to address the voiding symptoms.
• This procedure successfully decompressed the bladder diverticulum.
• The decompression led to the resolution of the ureteric obstruction and hydronephrosis.

Implications:

• Bladder diverticula, though uncommon, can cause significant complications like ureteric obstruction.
• Bladder neck incision is an effective treatment for resolving voiding symptoms and associated complications.
• This case highlights the importance of considering bladder diverticula in patients with unexplained urinary symptoms and hydronephrosis.
