ABSTRACT

Various foreign bodies have been reported in the literature. Foreign bodies in the urinary bladder may occur through the urethra or migration from the neighboring organs. Here, we report a case of bladder stone formation because of the retained Foley catheter balloon in the urinary bladder. A 45-yearold woman was referred to our clinic with right flank pain by an obstetrics and gynecology clinic. Urinary system ultrasonography revealed a bladder stone with a diameter of 25 mm, and cystolithotripsy was planned. Cystoscopy revealed a bladder stone approximately 3 cm in diameter, and cystolithotripsy was performed. The latex material was detected at the end of lithotripsy, and it was removed via endoscopic foreign body forceps. An examination of the foreign body revealed a retained Foley catheter balloon. Retained catheter fragments can potentiate many complications such as bladder stone, recurrent urinary tract infections, irritative voiding symptoms, bladder tumors, fistula formation, bladder perforation, and periurethral abscess. It has been well documented that catheter fragments frequently serve as nidus for calculus formation. In women, the potential intravesical foreign body must be considered in bladder stone cases because of which an intravesical obstruction is rarely seen. Our case is important in terms of being an example for this knowledge. In conclusion, presence of a foreign body must be considered in female patients with bladder stone. (JAREM 2015; 5: 131-3)
