Giant Vesical Calculus Formation as a Complication of Augmentation Cystoplasty.

A 44-year-old female presented with the history of recurrent UTI and intermittent hematuria. She underwent augmentation ileocystoplasty for small capacity bladder 19 years back. Patient was on clean intermittent catheterization (CIC) since then. Abdominal radiograph and ultrasonography showed the large vesical calculus. Open cystolithotomy was done, and a yellowish brown hard stone weighing 1025 g was removed. Chemical analysis revealed struvite stone. Postoperative period was uneventful. Regular bladder wash, lifelong surveillance and follow-up is advisable.
