不论自发的或术后的尿外渗,均需立即诊断处理。有尿渗漏的术后病人,需要一系列的尿路检查包括瘘管造影以确定尿外渗的部位。作者分析了用CT及一般X线检查的各种尿外渗病人共15例;膀胱、肾、输尿管外科手术后尿漏11例,输尿管阻塞自发尿外渗3例,脓肾尿漏1例。15例均为CT确诊。有7例CT比尿路X线片更好地显示了尿积聚的情况,2例在平片上未看到的残余或复发癌为CT发现,在一例病人CT发现了第二个原来未料到的尿外渗部位。结合有代表性的病例,作者提出输尿管阻塞造成的自发性尿外渗用排泄性尿路造影常可诊断,但症状不典型者则诊断有困难;泌尿科病人术后自引流处漏尿是术后并发症的早期征象,造影检查时可因肾功能损害或造影剂稀释而显影不好;有些术后尿外渗是复杂的外科问题,一般X线检查可能找不到准确的漏尿部位。以上问题用CT
Regardless of spontaneous or postoperative urine extravasation, require immediate diagnosis and treatment. Postoperative patients with urinary leakage require a series of urinary tract examinations including fistula imaging to determine the site of extravasation. The authors analyzed a total of 15 patients with various types of extravasation by CT and general X-ray examination; 11 cases of urinary leakage after bladder, kidney and ureter surgery, 3 cases of spontaneous ureteruria with ureteral obstruction, and 1 case of urinary leakage from pus. 15 cases were confirmed by CT. 7 cases of CT showed better urinary accumulation than urography, 2 cases of residual or recurrent cancer not seen on plain film were found by CT, and in the case of one patient, a second unrecognized Urine extravasation site. Combined with a representative case, the authors suggest that ureteral obstruction caused by spontaneous urinary excretion with urinary tract urography often diagnosed, but atypical symptoms are difficult to diagnose; urinary tract leakage after surgery is from the drain Early signs of postoperative complications, angiography may be due to renal damage or contrast agent dilution and development is not good; some postoperative urinary extravasation is a complex surgical problems, the general X-ray examination may not find the exact location of leakage of urine. The above problem with CT
