Infravesical obstruction results as giant bladder calculi

Area of Science:

• Urology
• Surgical Case Report

Background:

• Bladder stones (vesical calculi) can cause significant lower urinary tract symptoms.
• Pelvic trauma is a potential, though uncommon, predisposing factor for bladder stone formation.

Purpose of the Study:

• To report an unusual case of giant bladder stones causing complete outlet obstruction.
• To highlight the management of massive vesical calculi in a patient with a history of pelvic trauma.

Main Methods:

• Plain radiography for initial stone visualization.
• Cystolithotomy for the removal of a large bladder stone.
• Pneumatic lithotripsy for fragmenting a second large bladder stone.

Main Results:

• Identification of two giant bladder stones, measuring up to 6.0 × 5.0 cm.
• Surgical removal of one stone (400g) and fragmentation of the second.
• Complete resolution of bladder outlet obstruction post-operatively.

Conclusions:

• Giant bladder stones, while rare, can cause severe urinary obstruction.
• Prompt surgical intervention is crucial for managing obstructive vesical calculi.
• This case represents one of the largest bladder stones reported, emphasizing the importance of considering stone formation after pelvic trauma.
