A 15 1/2-year-old girl with disseminated lupus erythematosus presented with acute flank pain and hematuria during oral anticoagulant therapy for thrombophlebitis of the lower extremities. The intravenous pyelogram demonstrated multiple filling defects of the renal collecting system interpreted as pyelocalyceal submocosal hemorrhage. This benign complication disappeared following adjustment of the anticoagulant therapy. An identical appearance has been described in a case of aplastic anemia, Henoch-Schonlein purpupa, and in renal truma. Submocosal hemorrhage of the renal collecting system is to be differentiated from pyeloureteritis cystca, uroepithelial tumor, vascular impressions from collateral circulation and submucosal edema.
一名15岁半患有播散性红斑狼疮的女孩，在接受下肢血栓性静脉炎口服抗凝治疗期间出现急性胁腹痛和血尿。静脉肾盂造影显示肾盂肾盏系统有多个充盈缺损，被解释为肾盂黏膜下出血。调整抗凝治疗后，这种良性并发症消失。再生障碍性贫血、过敏性紫癜和肾外伤的病例中也有类似表现。肾盂肾盏系统的黏膜下出血需与囊性肾盂输尿管炎、尿路上皮肿瘤、侧支循环的血管压迹和黏膜下水肿相鉴别。
