WUHAN, CHINA — A man in China was shookt to discover that he'd basically amassed a massive ostrich-sized bladder stone inside him.<br /><br />According to KanKan News, 55-year-old Mr. Zhou from Wuhan liked to stay up all night playing mahjong, with no bathroom breaks. He also didn't hydrate enough.<br /><br />Back in June, Zhou felt a painful bulge in his lower abdomen, and found it difficult to pee, so he decided to get medical help.<br /><br />Doctors at a local hospital found a huge mass as big as an ostrich egg lodged inside his bladder, and recommended immediate surgery.<br /><br />The giant stone was fished out during the open cystostomy and later shown to their maker, who will probably think twice before he holds in his pee again.<br /><br />At 13 centimeters long and weighing nearly a kilo, the hospital said it's the biggest they've ever removed.
