Isolated rupture of the renal pelvis secondary to blunt trauma is rare, though there is increased incidence in the setting of a pre-existing renal abnormality that predisposes the kidney to injury. We report a case of post-traumatic hemorrhage into the renal collecting system leading to delayed rupture of the renal pelvis in the setting of suspected chronic ureteropelvic junction obstruction. This case illustrates the difficulty in diagnosis of acute hemorrhage into the renal collecting system. Special attention should be given to a kidney with a pre-existing abnormality in the setting of trauma to prevent complications. A literature review of hemorrhage into the collecting system along with appropriate imaging and management are discussed.
钝性创伤继发的肾盂孤立性破裂很少见，不过在存在使肾脏易受损伤的既往肾脏异常情况下，其发生率会增加。我们报告一例创伤后肾集合系统出血，导致在疑似慢性输尿管肾盂连接处梗阻的情况下肾盂延迟破裂。该病例说明了肾集合系统急性出血的诊断困难。对于创伤情况下存在既往异常的肾脏应给予特别关注，以预防并发症。本文讨论了关于集合系统出血的文献综述以及适当的影像学检查和处理方法。
