10 patients with blunt renal trauma have been studied and compared by the excretory urography and renal angiography in the Department of Urology, National Medical Center, Seoul, during the period of January 1976 through June 1977. The following results were obtained: 1) Renal angiography is a more specific diagnostic procedure than the excretory urography in detailing the extent of injury. And it provides more opportunity of a high salvage rate of injured kidney. 2) In a normal excretory urography, renal angiography need not do in deciding surgical management of renal injury. 3) The result of positive renal angiograms was especially great in patients showing any of the following urographic abnormalities; non-or poor visualization and extravasation of contrast media. 4) Surgical intervention was done in only one patient of renal thrombosis.

Horseshoe adrenal gland is a rare congenital abnormality associated with multiple congenital anomalies that may involve the cardiovascular, central nervous, and genitourinary systems. In this report, we describe the sonographic findings of horseshoe adrenal gland in a newborn with right isomerism a frequently associated cardiovascular anomaly.

This rare venous congenital anomaly has been diagnosed preoperatively in a 24-year-old female with complaints of the right flank and low back pain, and urinary frequency. In the I. V. P. the dilated upper right ureter forms a reversed "J" appearance. The right R.G.P. shows the "S"-shaped course of the ureter. The vena cavogram discloses crossing with the right R. G. P. at L3-4 intervertebral space level. 2.5cm. of strictured, postcaval segment of ureter is excised and end-to-end oblique anastomosis is done over splinting ureteral catheter. 4 months after the operation, the I. V. P. shows marked improvement of hydronephrosis and satisfactory drainage of urine compared with the preoperative films.

One of the sequelae of spinal cord trauma which start soon after the onset of injury is the loss of the calcium from bone. Bone mineral and matrix resorption causes negative calcium balance, and eventually osteoporosis. Etidronate disodium(etidronate) is an oral diphosphonate compound known to reduce bone resorption through the inhibition of osteoclasic activity. Since continuous oral treatment with high doses of etidronate may lead to the impairment of bone mineralization and the cessation of bone remodeling, a ideal therapeutic regimen consist of the intermittent cyclical administration of the diphosphonate in a dose that inhibits bone resorption. To assess the effect of etidronate on bone metabolism and bone mineral density after spinal cord injury, we studied two groups of 7 spinal cord injury(SCI) patients with etidronate and 7 SCI patients without etidronate. Seven patients of treatment group received oral etidronate (5 mg/kg/day) for 2 weeks followed by a 10-week period in which no drugs were given. This sequence was repeated 4 times, for a total of 48 weeks. The results showed that the patients receiving etidronate had siginificant decrease in the serum osteocalcin(OC), urine deoxypyridinoline(D-PYD) level but no increase in their mean bone density. We can carefully conclude that intermittent cyclical therapy with etidronate siginificantly reduces bone metabolic rate and inhibit bone mineral loss on osteoporosis in spinal cord injury patients.

Purpose: This study aims to evaluate the incidence and management of venous ruptures after percutaneous transluminal angioplasty (PTA) for dysfunctional arteriovenous (AV) access. Materials and Methods: From January 1998 to December 2015, 13506 PTA, mechanical thrombectomy, and thrombolysis procedures were performed in 6732 patients. The venous rupture rate following PTA was obtained, and access circuit primary patency (ACPP) was compared according to the etiology (PTA, thrombotic occlusion, and treatment type) of the venous rupture present. Results: Venous rupture developed in 604 of the 13506 procedures. Venous ruptures were more frequent in female, AV graft cases, and in cases accompanied by thrombosis. Balloon tamponade was performed in 604 rupture cases, and stents were deployed in 119 cases where contrast extravasation and flow stasis persisted. ACPP was significantly better in the non-ruptured AV access circuits than in the ruptured group. However, AV access type and thrombosis was not associated with primary patency. In ruptured cases, ACPP is 8.4 months for prolonged balloon tamponade and 11.2 months for bare-metal stent insertion, showing statistically significant difference. Conclusion Balloon tamponade and bare-metal stent placement are effective treatment for PTA-induced venous ruptures. In particular, stent placement showed a similar ACPP to that of non-ruptured AV access circuits.
