To report an unusual case of inferior vena cava obstruction secondary to urinary retention.
METHODS/RESULTS: A 72-year-old male patient with a history of bilateral inguinal hernia and a recent hip surgery, presented with deep venous thrombosis in the left leg. A CT scan disclosed significant thickening of the bladder wall and grade III-IV hypertrophy of the prostate. Abdominal ultrasound disclosed a cystic mass compressing the vena cava and moderate ureterohydronephrosis. Edema spontaneously resolved following insertion of a urethral catheter and renal function returned to normal.
Obstruction of the inferior vena cava secondary to an enlarged bladder is rare. To our knowledge only two such cases have been reported in the literature. In the case described herein, urinary retention may have been exacerbated by prostatic hypertrophy, anesthesia and bed confinement due to hip surgery.
报告一例因尿潴留继发下腔静脉梗阻的罕见病例。
方法/结果：一名72岁男性患者，有双侧腹股沟疝病史且近期接受过髋关节手术，出现左腿深静脉血栓形成。CT扫描显示膀胱壁明显增厚，前列腺III - IV级肥大。腹部超声显示一个囊性肿块压迫下腔静脉，伴有中度输尿管肾盂积水。插入导尿管后水肿自行消退，肾功能恢复正常。
膀胱增大继发下腔静脉梗阻较为罕见。据我们所知，文献中仅报道过两例此类病例。在本文所述病例中，前列腺肥大、麻醉以及髋关节手术导致的卧床限制可能加剧了尿潴留。
