Huge urinoma caused by spontaneous ureteral rupture secondary to ureteral obstruction due to prostate cancer

Dear editor,Spontaneous ureteral rupture(SUR)due to prostate cancer is very rare.The most common cause is calculus.To the best of our knowledge,SUR secondary to ureteral obstruction caused by prostate cancer was first reported by Deng et al.[1],so this case may be the second report.We report a case of a huge urinoma caused by SUR secondary to prostate cancer that was difficult to treat.This case is significant because the long-term presence of urinomas has never been reported.
