Hanging bladder stone due to misplaced surgical suture several years after hysterectomy: A case report

Urinary bladder calculi are rarely seen in women and any history of previous pelvic surgery must, therefore, raise suspicion of an iatrogenic etiology. The incidence of iatrogenic foreign bodies rise recently due to increasing number of surgical procedure. According to the literature, fewer than 2% of all bladder calculi occur in female subjects and, thus, their presence should provoke careful assessment of the etiology. There have been a number of reports on bladder calculi in women with a history of gynecologic procedures. We report a case of bladder calculus after hysterectomy that was treated successfully by open surgery_. CASE PRESENTATION: A 54 year old lady with dysuria, had a history of urinary stone for one last year. She was complaining hematuria. She had radical hysterectomy 20 years ago and cystoscopy Lithotripsy because of bladder stone a year ago. Physical examination was unremarkable. Abdominal CT scan with contrast had revealed multiple vesicolithiasis and irregular calcifications attached to the superior aspect of vesical urinary.

Cystoscopic evaluation was performed and confirmed presence of calculi forming around several surgical sutures fixed to the bladder wall. The intravesical calculus had developed from non-absorbable sutures and hung on the dome of the urinary bladder. The stone and residuum of the suture were retrieved by performing an open surgery.

The presence of an intravesical stone should be suspected in patients with a history of hysterectomy who have symptoms in the lower urinary tract. A hanging stone on the dome of the urinary bladder implies that non absorbable suture materials intrusion into the urinary bladder. The complication can be prevented by the routine use of absorbable material and doublechecking with cystoscopy.
