Massive vesical calculi formation as a complication of augmentation cystoplasty

Here we report an unusual case of massive stone formation in augmented urinary bladder.

A 25-year-old man presented with recurrent urinary tract infection ten years after augmentation cystoplasty after a complex pelvic fracture urethral distraction defect. On evaluation by ultrasonography, X-ray, and computed tomography of abdomen showed large burden of stones in the urinary bladder. Patent underwent an open cystolithotomy and forty stones weighing about 1400 g were removed. It was one of the largest reported stone burdens following augmented cystoplasty until now.

Even though stone formation is a common complication after augmentation cystoplasty, it can be prevented by regular bladder wash and good follow-up.
