Review Case Reports
[Complete avulsion of ureter caused by abdominal blunt injury: a case report].
A 21-year-old woman who had been injured in a traffic accident appeared with abdominal pain and macroscopic hematuria. Computed tomography (CT) performed 6 hours after the injury showed extravasation of contrast medium in the right retroperitoneal space. ⋯ We observed a completely separated right ureter at the ureteropelvic junction, and performed an end to end anastomosis. The patient was discharged three weeks after surgery, and has not had any problems for three years.

Review
[Two cases of ammonium acid urate urinary stones related to anorexia nervosa and laxative abuse].
We report two cases of urolithiasis related to anorexia nervosa and laxative abuse. Case 1: A 21-year-old woman was referred to our hospital because of left flank pain. A left ureteral stone, 10 x 6 mm in size, was successfully fragmented by extracorporeal shock-wave lithotripsy (ESWL), but she experienced repetitive formation of bilateral urinary stones and double J stent encrustation which required 13 sessions of ESWL, one session of transurethral ureterolithotripsy and one session of cystolithotripsy over a period of 5 years. ⋯ She was later diagnosed with anorexia nervosa and it turned out that she had suffered from an eating disorder and laxative abuse (bisacodyl, 200 mg/day) since the age of 15 years. Both patients had marked decrease in urine volume, hyponatremia and hypokalemia. Anorexia nervosa and laxative abuse should be suspected whenever a woman has an ammonium acid urate stone in sterile urine because the treatment of these disorders is crucial to the prevention of repetitive formation of urinary stones.
