One rare case of spontaneous rupture of pyelocaliceal diverticulum is reported in a 31-year-old Japanese man presented with a severe left flank pain. Intravenous pyelography and computerized tomography demonstrated extravasation of contrast medium from his diverticulum which contained numerous calculi. As a possible cause of spontaneous rupture of pyelocaliceal diverticulum in this case, we suggest that the paper-thin parenchyma covering the diverticulum was not strong enough to tolerate the minimum elevation of intrapelvic pressure due to the obstruction of delivered stones.
本文报道了一例31岁日本男性肾盂肾盏憩室自发性破裂的罕见病例，该患者表现为严重的左侧腰痛。静脉肾盂造影和计算机断层扫描显示，其憩室内有大量结石，造影剂从憩室外渗。对于该病例中肾盂肾盏憩室自发性破裂的可能原因，我们认为覆盖憩室的薄壁实质组织不够坚韧，无法承受由于排出的结石阻塞导致的肾盂内压力的最小升高。
