Large infectious bladder stone after long delay in removing ureteral stent

Area of Science:

• Urology
• Nephrology

Background:

• Indwelling urinary catheters, such as double pigtail catheters, are common in managing various urological conditions.
• Prolonged use of these devices can predispose patients to complications, including infection and stone formation.

Observation:

• This case highlights the formation of a large, infectious bladder calculus.
• The calculus developed secondary to the prolonged placement of a double pigtail catheter.

Findings:

• The patient presented with a significant bladder stone attributed to the indwelling catheter.
• Coexisting poor function of the ipsilateral renal unit complicated the clinical picture.

Implications:

• The findings underscore the risk of bladder stone formation with long-term catheterization.
• Nephroureterectomy became the unavoidable treatment option due to the stone burden and renal impairment.
