Transcatheter renal artery embolization in treatment of ureterocutaneous fistula.

We report a case of a critically ill patient who had a ureterocutaneous fistula develop after placement of a Dacron bypass graft from the aorta to the right popliteal artery and the left femoral artery. We describe a successful nonsurgical method to terminate renal function in this patient, who was a poor operative risk.

The caudad angle view: a helpful adjunct in excretory urography.

The caudad angle view is a useful ancillary projection for evaluating renal morphology during excretory urography. This view, easily obtained during routine urography, often adds important information about renal anatomy and patholgoy which is not apparent on conventional radiographs.

Radiographic manifestations of Japanese acupuncture.

The radiographic manifestations of Hari, a peculiar type of acupuncture currently practiced in Japan, are described. This acupuncture method consists of inserting multiple fine gold needles through the skin into the subcutaneous tissue. The needle is cut off at the skin surface and left in the subcutaneous tissue for the life of the patient. These multiple needles present curious, frequently unsuspected findings on radiographs obtained for reasons unrelated to acupuncture.

Evaluation of pelvic masses during infusion excretory urography.

Infusion excretory urography not only clearly delineates the urinary tract structures, but provides additional information about the type of pelvic mass present. Benign uterine fibroids show contrast enhancement in a significant number of cases, whereas endometrial and cervial malignancies give no specific pattern. Cystic and mixed ovarian neoplasms show rim opacification in over 50 per cent of cases, and the presence of this rim sign points strongly to an ovarian lesion. The opacification of solid ovarian tumors cannot be differentiated from that of uterine fibroids unless other identifying features such as specific calcification or visualization of a normal uterus are present. Pelvic inflammatory disease shows no specific type of opacification. Excretory urography is part of the preoperative evaluation in most patients with pelvic mass lesions. By utilizing the infusion method, high quality excretory urograms are obtained, and, in addition, helpful information is obtained regarding the type of pelvic mass present.

Abdominal computed radiography: evaluation of low-constrast lesions.

Computed radiography has proved useful as a localization device for computed tomography. In an attempt to evaluate computed radiography as a primary diagnostic device, 16 patients were evaluated with various degrees of gallbladder opacification following standard oral cholecystograms, and 15 patients were evaluated with renal masses, identified on standard excretory urography. Subjective evaluation of computed radiographs as compared to the standard radiographs demonstrated no diagnostic advantage to computed radiography. The poor spatial resolution of the computed radiographs was not overcome by the improvement in contrast resolution.

Reliability of Doppler and impedance techniques for the diagnosis of thrombophlebitis.

The accuracy of Doppler ultrasound and impedance diagnostic techniques for identifying deep venous thrombosis was determined by comparison with patient venograms. Those patients suspected of having deep venous thrombosis were tested by ultrasound, impedance, and venography, with venography the standard for establishing the accuracy of the noninvasive methods. The deep inspiration, the Valsalva and abdominal pressure maneuvers, and the pneumatic cuff technique were employed with the impedance tests. The incidence of false negative and false positive results were determined for each noninvasive method separately and for both methods used concurrently. When both methods were considered, the number of false positives was high; however, all cases with major thrombosis were detected in the group of patients examined. A positive result with ultrasound or impedance tests should be considered an indication to perform venography, or if venography is contraindicated, to perform other noninvasive tests.
