[Bladder stones caused by spontaneous migration of surgical staples after cloacal repair: a case report].
An 11-year-old female consulted our department with complaints of urinary incontinence and pyuria. She had had a cloacal repair 7 years ago. The radiograph showed four stones in the pelvis. Magnetic resonance imaging showed two diverticula next to the urethra and several low intensity masses in one diverticulum were regarded as stones. Voiding cystourethrography showed normal urinary bladder contraction, although there were residual urine in the diverticula. Preoperatively, these stones were thought to be formed as a result of the long-standing residual urine. Cystourethroscopy showed that the two diverticula existed within the proximal area of the urethral sphincter and four white stones were found in them. Transurethral cystolithotripsy was performed and a surgical staple was found in the core of each stone. The surgical staples had been used for the cloacal repair and they had migrated into the bladder resulted in stone formation. To the best of our knowledge, this is the first report of bladder stones caused by the migration of surgical staples into the bladder after cloacal repair.
