INTRODUCTION
Radical cystectomy is the standard treatment for muscle-invasive bladder cancer. A neobladder is created as part of urinary diversion; however, the formation of bladder stones is often a late complication-related concern.
CASE PRESENTATION
A 56-year-old man underwent radical cystectomy and neobladder construction for bladder cancer 25 years ago. A huge neobladder stone was diagnosed when the patient developed a strangulated ileus. Open surgery was performed to remove the bladder stone. The stone's size was 21.6 × 15.5 × 18.5 cm and its weight was 5 kg.
CONCLUSION
To the authors' knowledge, this is the largest case of bladder calculus reported to date.
引言
根治性膀胱切除术是肌层浸润性膀胱癌的标准治疗方法。新膀胱作为尿流改道的一部分被构建；然而，膀胱结石的形成往往是一个与晚期并发症相关的问题。

结论
据作者所知，这是迄今为止报道的最大膀胱结石病例。
