Among a series of 3100 patients with urologic disease, treated over a period of 7 years, chronic renal failure (CRF) had 161. In rank order CRF was most common in patients with prostate adenoma (36.02 per cent), followed by patients with renal calculosis (27.33 per cent) and renal cancer (10.56 per cent). The causes of CRF and its dynamics, depending on the underlying disease, the therapeutic approach and the principles of treatment are discussed in detail. The inferences from the experience gained at the clinic point to the need of accentuating the attention of urologists and nephrologists for early diagnosis and adequate treatment of urologic diseases, which might cause CRF. The principles of its treatment are outlined.

We describe a case of advanced chronic renal failure with persisting hypokalemia. The clinical study revealed the simultaneous presence of a salt and potassium loosing nephropathy associated with aldosterone-producing adenoma. This late pathology was revealed as electrolytic changes characteristic of primary hyperaldosteronism became evident as the renal function progressively deteriorated.

A 48-year-old man was admitted for treatment of Cushing's syndrome due to right adrenal adenoma, associated with chronic renal failure (CRF) with a blood urea nitrogen level of 64.2 and serum creatinine level of 3.9 mg/dl. After removal of the adrenal adenoma, the CRF deteriorated with progressive symptoms of anorexia, vomiting and hypertension, and the patient was placed on hemodialysis. Prior to adrenalectomy, the 17 OHCS and 17 KGS in the urine were not so high. However, the urinary 17 KS was high with an elevated 11-oxy fraction. In comparison with 2 patients suffering from adrenal Cushing's syndrome with normal renal function, there were no large accumulated quantities of glucuronic conjugated and unconjugated metabolites in the plasma of the CRF Cushing's syndrome, with confirmation ascribable to the radioimmunoassayable cross-reactivity of the cortisol antiserum used in the radioimmunoassay kit. In the Cushing's syndrome with CRF, almost all the cortisol, which was hypersecreted from the adenoma, was presumed to be converted to the 11-oxy fraction of 17 KS, possibly by activation of hepatic enzymes.

Successful renal transplantation may be complicated by persistent hyperparathyroidism due to diffuse parathyroid hyperplasia remaining from a prolonged period of pretransplant chronic renal failure treatment. Posttransplant hyperparathyroidism is distinct from primary hyperparathyroidism, being characterized by multiple gland involvement and diffuse hyperplasia rather than a single adenoma. The gross pathologic anatomy of the parathyroid glands was assessed in 17 successful renal transplant recipients. Individual and total gland volumes were measured at the time of total parathyroidectomy and forearm reimplantation. Parathyroid hyperplasia was heterogenous in both location and gland size. Right-sided glands were enlarged more than left-sided ones. Subjects with primary tubulointerstitial disease exhibited greater hyperplasia than patients with glomerular disorders. Clinicians should be aware of the heterogeneity of the gland enlargement in patients with diffuse parathyroid hyperplasia, so that these patients are not misdiagnosed as suffering from adenomatous parathyroid disease.

A 45-year-old Japanese woman who has been receiving haemodialysis for 13 years suffered from an ectopic calcifying nodule and deformity of the thorax. She was diagnosed as hyperparathyroidism secondary to chronic renal failure. Total parathyroidectomy was performed, and the excised parathyroid glands showed hyperplasia in four and an adenoma in the left upper gland. On the electron microscopic study, the adenoma was composed of oxyphil cells and transitional oxyphil cells, the latter predominating in number. It was revealed from immunohistochemical study that the oxyphil cells in adenoma were strongly stained for parathyroid hormone (PTH). Continuous stimuli to secrete PTH seemed to generate the functioning oxyphil cell adenoma with an ability of PTH production, as well as hyperplasia of parathyroid chief cells. It seems to be the first case of tertiary hyperparathyroidism caused by an oxyphil cell adenoma. Functions of oxyphil cells and transitional oxyphil cells are briefly discussed.

The metabolic bone disease associated with chronic renal failure has been described collectively by the terms "renal osteodystrophy" or "renal-glomerular-osteodystrophy" and consists of osteomalacia, osteitis fibrosa, and osteosclerosis. The skeletal abnormalities may occur either alone or in combination with one another. An increased concentration of circulating immunoreactive-parathyroid hormone (i-PTH) is a recognized feature of patients with chronic renal failure, and the values are usually much higher than those found in patients with primary hyperparathyroidism associated with a parathyroid adenoma. It must, however, be recognized that the high circulatory concentrations of parathyroid hormone found in patients with chronic renal failure are of immunoassayable material which may or may not be of biological significance in respect of activity. A disturbance in the homeostatic control mechanism governing parathyroid hormone, the secretion rate, its metabolism, and target organ resistance to its action are of major importance in the pathogenesis of some aspects of the metabolic bone disease in patients with chronic renal failure. The pathogenesis of the secondary hyperparathyroidism of chronic renal failure, however, also involves disturbances in cholecalciferol metabolism, phosphate retention, and the uremic state per se.

ACTH and lipotropins (beta- and gamma-LPH) are synthesized from a common precursor by the pituitary corticotropic cell. We have measured LPH plasma levels under physiological and pathological conditions and we have compared them with ACTH plasma levels in the same circumstances. Spontaneous variations (nycthemeral rhythm) in LPH, ACTH and cortisol plasma levels were parallel, while responses to Dexamethasone freination test and stress (Insulin induced hypoglycemia) or more specific stimulation (Metopirone, lysine-vasopressin) were parallel and superimposable. LPH levels were always higher than ACTH levels in two pathological circumstances: chronic renal failure and Cushing's syndromes with ectopic ACTH producing tumors. The determination of both ACTH and LPH levels assists the diagnosis of corticotropic insufficiency and etiologic investigation of Cushing's syndrome, after hypercorticolism had been established. Although unable to confirm the presence of corticotropic adenoma in patients with Cushing's disease, or the predict effectiveness of pituitary surgery, these determination bring good arguments for treated Cushing's diseases follow up.

Intense diffuse uptake of Tc-99m-labeled methylene diphosphonate was seen in both lungs of a patient submitted to surgery for a primary parathyroid adenoma. Five scans performed over the 3 yr following the operation showed persistence of lung uptake despite restoration of normal blood calcium concentration. Mild chronic renal failure caused by the hypercalcemia also persisted postoperatively. The present case confirms that pulmonary uptake of bone tracer can occur asymptomatically when both hypercalcemia and renal failure are present. Lung uptake of a bone tracer probably reflects tissue deposition of hydroxyapatite rather than of amorphous structures. Correction of the hypercalcemia failed to resolve the abnormal scan pictures.

An aldosterone-producing adenoma (APA) was associated with chronic renal failure. Following treatment with Trilostane (a 3 beta-hydroxysteroid dehydrogenase inhibitor), furosemide and continuous ambulatory peritoneal dialysis (CAPD), a left adrenal adenoma was successfully removed. This patient, still being treated with CAPD, is a unique example of primary aldosteronism without showing suppressed plasma renin activity.

A 49-year-old woman at recent climacterium was admitted to our hospital for a dyspeptic-type symptomatology, weight loss, bone pain, moderate polyuric-polydipsic syndrome and in a marked astheno-depressive state. Paraclinical explorations revealed constant hypercalcemia with hypophosphoremia, calciuria, chronic renal failure in the polyuric phase with retention of nitric bases. X-ray films showed diffuse osteoporosis, right nephrocalcinosis and diffuse calcifications of the galactophorous ducts in both breasts. Computerized tomography revealed and surgery confirmed the presence of tumoral tissues on the anterior aspect of the trachea. Histopathologic examination revealed a parathyroid adenoma.
