More than ten years experience with the enteroclysis technique have shown that frequently disappointing results are achieved, always due to technical faults in the performance of the technique. In this article the most important factors for proper technique and the most frequently occurring causes of bad results are mentioned.

Introduction of the thin flexible needle (Chiba or Okuda needle) has revived percutaneous transhepatic cholangiography, even though there are more recent methods of investigating the biliary tract. Personal results in 65 patients demonstrate that the needle can be successfully introduced in all instances, as long as the biliary tracts are dilated, the success rate being 68% if they are not. The complication rate was 9.2%, but there was no death.

Neurofibromas and phaeochromocytomas derive ultimately from ectodermal tissue. It is therefore not surprising that there is an increase in the incidence of phaeochromocytomas in Recklinghausen's neurofibromatosis. When investigating hypertension in patients with neurofibromatosis one must therefore consider the possibility of a phaeochromocytoma as well as vascular involvement by neurofibromatosis. Two patients with neurofibromatosis and phaeochromocytomas are described.
The article discusses the y-ray diagnosis of the Zollinger-Ellison syndrome, including 13 with multiple endocrine adenomatosis, Type I. This syndrome is governed by complex pathophysiological processes determining the x-ray symptoms. Besides the predisposition to ulcers, which will persist despite partial gastrectomy, changes at the duodenum (hypertrophy of Brunner's glands) and proximal jejunum (bulging of folds) are relatively typical. However, the final diagnosis of the Zollinger-Ellison syndrome is a clinical one. The syndrome is caused by non-beta islet cell tumors of the pancreas, associated with hypergastrinemia. Since these tumors are often multiple and small, angiography is not very rewarding. It is frequently impossible to distinguish the benign from the malignant tumors on the grounds of histological findings, the only criterion being their biological behaviour, if the exclusion or identification of metastases.
In 110 patients 119 renal transplantations were performed from 1968 until May 1, 1975. In this survey data are given on the recipients and the transplanted kidneys. For the following papers on different complications with renal transplantation the X-ray pictures taken until May 1, 1976 were reviewed and correlated with clinical findings.
The uroradiological changes and complications with 110 patients who did undergo a total of 119 renal transplantations are discussed under the following 4 topographical headings: perirenal and intrarenal, ureter including the anastomosis, bladder, urethra. In our material we found a lymphocele in 1 patient, papillary necrosis in 3, ureteral obstruction in 6, urinary leakage in 23, reflux in a total of 23, renal calculi in 1 and bladder concrements in 1.
The article describes the authors' experience in their Department in Nijmegen (Holland) with the various types of x-ray equipment: in gastroenterology--especially in the examination of the small intestine, colon, and the bile ducts--and also within the framework of a general roentgenology diagnostics section. Problems of cost are also considered, relating on the one hand to the equipment required in an examination room, and on the other hand to gastroenterological examination. In conclusion, the authors suggest the most suitable type of apparatus to be acquired for a particular purpose.
Bifid ureter with blind-ending branch must fulfill the criterias of Culp. Retardation of ureter growth or degeneration of a ureteral segment after fusion with the metanephrogenic tissue are to be considered as the cause for this anomaly. Infrequently other, preferably congenital lesions of the kidneys or other organ systems are combined. The bifid ureter with blind-ending branch can be a casual finding. But it may cause symptoms which make resection necessary. The diagnosis is possible by excretory urography. Two cases are added to the known 66 patients in the literature.
Successful embolisation with Gelfoam of renal hemorrhage caused by surgery. Embolisation was made easier by the fact that bleeding originated from the smaller of the three arteries for the right kidney. No persistence of hypertonia. Formation of intrarenally localised renorenal collaterals.
When performing the enteroclysm according to Sellink, the barium suspension and subsequently water or air is infused, respectively insufflated, directly into the intestine by means of a Bilbo-Dotter tube. This method allows good morphological diagnosis.
A case is reported where postoperative hemorrhage from the kidney was successfully managed by selective transcatheter embolization of the bleeding vessel. A review of the literature reveals that only three papers have been published dealing with selective embolization for controlling hemorrhage from the kidney. Our case is another illustration of the possibilities and usefulness of this method of treatment in the management of persistent postoperative hemorrhage.
Vascular involvement in von Recklinghausen's neurofibromatosis has been known since the work of Reubi (1944, 1946). We found 72 cases of neurofibromatosis with renovascular hypertension reported in the literature. We have observed three female patients, of whom two had unilateral renal artery abnormalities consisting of stensoses and small aneurysms. The third patient, who had a right-sided nephrectomy for probable occlusion of the renal artery, had a coarctation of the abdominal aorta and complete occlusion of the left renal artery and of the coeliac-mesenteric trunk. There were, in addition, large, bilateral aneurysms in the circle of Willis.
One of the two main branches of the left renal artery was slowly occluded in four dogs. Repeated angiography was carried out from 45 to 61 days postoperatively; this made it possible to observe the development of collaterals between the normal and constricted branches of the renal artery, i.e. intrarenal renorenal collaterals. These collaterals developed predominantly from preexisting vessels of the extraglomerular system in the vicinity of the renal pelvis and calyces and, to a lesser extent, from medullary vessels and from forating capsular arteries.

Pseudoxanthoma elasticum is an hereditary disease of elastic fibres affecting the skin, eyes and the cardio-vascular system. The radiologist should be familiar with this disease; the vascular changes can lead to bleeding from the gastrointestinal tract, which can be elucidated angiographically. There may also be circulatory disturbances in the extremities associated with early and pronounced calcification of the media and intima.
