## TL;DR

A 40-year-old man with a history of bladder augmentation had six large, uniquely shaped bladder stones surgically removed.

## Contribution

This case report highlights the rare occurrence of multiple giant bladder stones with unusual geometric shapes.

## Key findings

- Six giant bladder stones, including pyramid and cube-shaped stones up to 7 cm in diameter, were successfully removed.
- The patient had no postoperative complications and was discharged on the 10th day after surgery.
- The case is notable for the high stone burden and unusual stone morphology.

## Abstract

Bladder stones are a common finding in urology practice although they are less common when compared to kidney and ureteral stones. This case report involves a male patient in his 40s with multiple giant bladder stones. The patient had neurogenic bladder disease due to spina bifida and had a history of bladder augmentation with continent urinary diversion when he was a child. He presented with difficulty in emptying bladder with clean intermittent catheterization. Open cystolithotomy was performed and six giant stones, five pyramid-shaped stones and a cube-shaped stone with a maximum diameter of 7 cm, were removed from the bladder. In our opinion, the rare occurrence of a high stone burden, stone weight and size, and geometric shapes of stones makes this case interesting. The patient was discharged from the hospital on the 10th day after the surgery and there were no postoperative complications.
