The degree of renal mobility was measured in patients with and without hypertension to evaluate a suggested causal relation between nephroptosis and hypertension. In contrast to men, women often showed pronounced renal mobility and the degree of renal mobility correlated positively with the blood-pressure. Fibromuscular dysplasia of the renal artery was always accompanied by a considerable degree of renal mobility on the side involved. The results of this study indicate that in women there may be an association between abnormal renal mobility and the development of high blood-pressure.

Scintigrams in prone and standing positions were done in 11 hypertensive women. All had nephroptosis with ventral rotation. On the basis of the renograms, seven patients were identified as suffering from orthostatic hypertension. Nephropexy resulted in normalization of blood pressure in six of the seven patients and normalization of the renograms of all seven. We believe that sequence scintigrams in prone and standing positions offer a simple method of identifying patients with orthostatic hypertension.

Vertical and medial nephroptosis was assessed on 60 consecutive excretory urographic examinations. Ptosis, both vertical and medial, was seen more commonly in females, and vertical ptosis was more frequent than medial ptosis. In our series there was no significant evidence of predominance on the right side. Dietl crisis, nausea, vomiting, hypotension, oliguria, or orthostatic hypertension were not encountered. Nephroptosis was mostly asymptomatic. In those patients with symptoms, lumbar pain was common and could be either aggravated or relieved by change in position. A new sign, paradoxic displacement, is described. This could be of value to the surgeon and radiotherapist in evaluating enlargement of a huge abdominal mass - a difficulat task to assess clinically.

The results of 76 selective renal angiographies in 33 patients with the use of adrenalin and acetylcholine are presented (17 cases of renovascular hypertension, 7-chronic pyelonephritis, 5-essential hypertension, 2-nephroptosis, 1-kidney tumor). The pecularities of the method essential for the success of the examination and prevention of complications are described. The importance of pharmacoangiography with adrenalin for the determination of the length of renal vessels lesion in cases of fibrous dysplasia was demonstrated, as well as that of the acetylcholine test for examining the state of the vascular bed of the contralateral kidney, the same procedures being applied in cases of chronic pyelonephritis. Typical pharmacoangiographic symptoms of different forms of nephrogenic hypertension are described.

Forty three patients with nephroptosis, complicated by hypertension were examined (4 males and 39 females), aged from 18 to 60. Permanent hypertension was found in nine of them (21%), and renovasographically--organic renal-arterial stenosis at the nephroptosis side was established. After the failure of the conservative treatment, those patients had all the indications for operation. Seven of the patients underwent the operation and only in one woman patient--nephrectomy was performed, and in all the rest six patients--reconstructive revascularization and nephropexy. The follow-up of the operated patients so far reveals a very favourable effect upon the hypertension syndrome after the operation.

The results of the examination and nephropexy operation in 11 patients with arterial hypertension and nephroptosis are presented; a hypotensive effect was achieved in 5 of the operated patients; the follow-up period was up to 3 years. The recordings included the elevation of the arterial pressure in orthostasis, the changes in the urine sediment, the activity of plasma renin at rest and after 1-hour's orthostasis; excretory urography and the Seldinger abdominal aortography in a lying and upright position of the patient were conducted, as well as intraoperative biopsy of the renal tissue. Patients with a hypotensive effect exhibited a regular elevation of the arterial pressure in orthostasis, an increased plasma renin activity, congestive features in the descended kidney. The above symptoms permit to distinguish groups of patients with a hypotensive effect achieved after nephropexy, and those without effect. On the basis of the obtained results it was concluded that in some cases nephroptosis may be the cause of symptomatic arterial hypertension. In such cases it seems rational to recommend the nephropexy operation taking into account, when determining the indications for surgery, the degree of the orthostatic elevation of the arterial pressure and of the renin activity, and the symptoms of disorders in the renal evacuation function.

The influence of postural changes on renal function was determined in 13 patients with nephroptosis and in 5 normal subjects by measuring GFR in the erect and supine positions. The result indicate that GFR was reduced in the erect position in 10 of 13 patients with either unilateral or bilateral nephroptosis whereas GFR was increased in the erect position in 4 of 5 patients without renal disease. One patient with bilateral nephroptosis and renovascular hypertension was studied before and after surgical correction of his disease. The observations indicate that patients with nephroptosis may have significant reductions in renal function when they assume an upright position, and suggest that GFR measurements in the supine and erect position in patients with nephroptosis can be helpful in evaluating this disease.

Renal artery aneurysms were diagnosed in 11 patients (9 boys) aged 1 to 14. The examinations were carried out for vasorenal hypertension in 4 cases, for bladder-ureter reflux, hematuria, nephroptosis in 4, ureterohydronephrosis in 2 cases, and for interstitial nephritis. Aneurysms of the major trunk of the renal artery, mostly oval-shaped, 11 x 14 to 25 x 28 mm in size, were detected in 4 patients, intrarenal aneurysms 2 x 3 to 5 x 6 mm in size in 7 cases. The share of aneurysms among uronephrologic conditions in children was found to be 1.54%, among vasorenal hypertension cases, 4.3%. Vasorenal hypertension is the main optional sign of aneurysms of the main trunk of the renal artery, whereas for intrarenal aneurysms such sign is hematuria.

The prevalence and patterns of the hypertension syndrome (AH) in young subjects require further study. An examination of 879 young subjects revealed AH in 14.6 per cent; in 84 inpatients borderline AH was found in 20.2, essential hypertension in 17.9 and symptomatic AH in 61.9 per cent, in 22.6 per cent AH was attended by signs of connective-tissue dysplasia and minor developmental abnormalities (mitral valve prolapse, nephroptosis, pathology of cervical spine, structural disorders of the lid slit and floor of the auricle, etc.). Manifestations of connective-tissue dysplasia and minor developmental abnormalities have a bearing on the AH formation and course in this group of patients. Further detailed study of the AH course in young subjects with these manifestations is required.

A 42-year-old woman presented with orthostatic hypertension. Increased plasma renin activity was noted and blood pressure rose gradually with standing. Selective renal arteriography indicated narrowing of the distal portion of the right renal artery and poststenotic dilatation and signs of arterial stenosis due to fibromuscular dysplasia. Greater arterial narrowing resulted from tortion due to nephroptosis brought about by excessive renin secretion. Thus, both renal arterial stenosis and nephroptosis were considered responsible for the present orthostatic hypertension. Percutaneous transluminal renal angioplasty was found very effective for normalizing standing blood pressure and renal blood flow.
