In a comparative period of 20 years is reported on the frequency of diabetes mellitus in urological diseases. It was found that 0.87% of the patients suffer from a concomitant diabetes. The peak of the disease is between the 60th and 70th year. As to the distribution of sex was established that the concomitant diabetes is to be found more frequently in males (ratio 2.4: 1). The lethality in diabetics with a urological disease is with 9.4% more than twice as high as in the other urological patients (4.3%). At the top of the immediate causes of death is the cardiovascular failure (30.7%), followed by the pulmonary blood clot embolism and the uraemic coma with 15.4% each. A diabetic coma never appeared. In the analysis of the urological diseases with concomitant diabetes the lithiasis (34.4%) is in the first place; then follow the adenoma of the vesical cervix (32.4%), the chronic relapsing pyelonephritis (12.9%), and the malignant tumours (7.1%). Many urological forms of diseases appeared combined. In the investigation of the complications without lethal exitus which appeared in 25.1% of all cases with concomitant diabetes the cardiovascular failure is again in the first place, then follow thrombotic diseases, urea-nitrogen disturbances. Peculiarities in conduction and treatment of the diabetes mellitus are shown and a close collaboration between several specialities is considered necessary.

In order to identify prolactin-producing tumours in human pituitary glands, 45 chromophobe adenomas, obtained from unselected necropsies, have been studied by various staining procedures including the immunoperoxidase technique for the demonstration of prolactin. The presence of immunoreactive prolactin was revealed in the cytoplasm of the tumour cells in six cases (13%), indicating that the occurrence of prolactin-producing adenomas is not rare. No correlations were established between tumours and clinical history. Two adenomas were detected in female and four in male patients. The age of the patients at necropsy ranged from 28 to 75 years. Three adenomas were associated with disseminated carcinoma, two with fatal liver disease, and one with diabetes mellitus, atherosclerosis, and pyelonephritis. Manifest endocrine symptoms were not disclosed, and endocrine investigations, including measurements of blood prolactin levels, were not undertaken. Thus, direct evidence is lacking as to whether or not these tumours were actively secreting prolactin. In the non-tumorous parts of the anterior lobes the number of prolactin cells was decreased in two cases, suggesting that prolactin released from the adenoma cells suppressed prolactin production in the non-tumorous pituitary. However, the number of prolactin cells of the non-tumorous adenohypophysis seemed to be unchanged in two and increased in another two cases. The present findings conclusively proved the existence of the prolactin-producing adenomas as a distinct entity. These tumours do not stain with acid or basic dyes, they are PAS or thionin negative, and do not contain immunoreactive growth hormone. Thus, by conventional staining procedures they are indistinguishable from other chromophobe adenoma types. Herlant's erythrosin and Brookes' carmoisine methods, claimed spedifically to stain prolactin cells, failed to provide reliable results, hence their use cannot be recommended in tumour identification. Immunoperoxidase staining of prolactin is the only technique which conclusively reveals the presence of immunoreactive prolactin in the cytoplasm of the tumour cells and permits diagnosis. It is proposed that this technique be introduced in pituitary morphological studies. Its application may lead to a better understanding of problems related to prolactin-producing tumours and their secretory activity.

The AgNOR argyrophil technique was applied to clear cut examples of renal adenoma (n = 7), clear cell carcinoma (n = 9), and xanthogranulomatous pyelonephritis (n = 5). There was no significant difference between mean AgNOR counts per cell in adenomas and carcinomas, supporting the idea that there is a continuous spectrum of kidney tumours. Xanthogranulomatous pyelonephritis and clear cell carcinoma showed significant differences in mean AgNOR counts per cell, suggesting that the technique may be of use in distinguishing between these conditions, although further cases may need to be examined to confirm this.

150 patients dying from renal cell carcinoma are studied in order to reveal the background disease, incidence and character of the nephrosclerosis and the possible morphogenetic link between nephrosclerosis and carcinoma. Renal cell carcinoma is found to develop in 82.7% of cases in the kidneys with signs of nephrosclerosis. The diffuse nephrosclerosis developing in connection with the hypertension disease, atherosclerosis, diabetes mellitus, chronic pyelonephritis, nephrolithiasis is the most important. Proliferation of the canaliculi epithelium with the appearance of undifferentiated cells are regularly found in the nephrosclerotic areas. The disturbance of the epithelium differentiation is followed by the development of dysplasia the phenotypical variants of which are similar to those of renal cell carcinoma. Adenomas are found in 11.3% of cases of renal cell carcinoma which may originate from the adenomas developing against the background of nephrosclerosis.

A case with multiple endocrine neoplasia was reported, including parathyroid adenoma, of the main cells of the gland, multiple small adenomas in the tail of pancreas, (cytologically and electron-microscopically determined as A cellular) and light-cellular adenoma of adrenal. The hyperfunction of parathyroid adenoma was manifested with hypercalcemia (3.75 mmol/l), and morphologically--with the multiple calcium metastases in lungs, kidneys and heart, established at necropsy. The cause for the death was the acutely advanced ischemic disease of myocardium, on the background of chronic pyelonephritis and renal insufficiency. The timely diagnosis of such morbid states is concluded to be important for the clinical practice and could lead to the saving of the patients by operative removal of the tumour.

The long-term results of surgical and specific drug therapy were compared in a group of 57 patients with primary aldosteronism (PA) (46 with aldosterone-producing adenoma (APA), 11 with idiopathic hyperaldosteronism (IHA) and bilateral adrenal hyperplasia). Unilateral adrenalectomy completely normalized blood pressure (BP) in 77.1% of surgically treated APA, evidently improving hypertension in remaining 22.9%. No recurrence of the adenoma in the remaining adrenal was seen in any of the surgical APA cases. In 19 of the non-surgical patients (11 with APA, 8 with IHA) monotherapy with spironolactone reduced blood pressure in 73%, though total BP normalization was an exception. The treatment normalized hypokalemia, low total exchangeable potassium, tendency to hypernatremia, and high total exchangeable sodium. Surgical as well as conservative therapy increased to normal or above-normal levels plasma renin activity suppressed prior to treatment. Pre-operatively high urine and plasma aldosterone levels normalized in all adrenalectomized patients, but remained above the normal range during spironolactone therapy in spite of a small decline in its absolute values. The disturbances of maximum renal concentrating capacity due to impaired nephron responsiveness to sufficiently high endogenous vasopressin concentrations were completely eliminated after kaliopenic nephropathy had been repaired. The other renal functions remained within normal values. Echocardiographically diagnosed left ventricular hypertrophy was seen less often than in the other types of arterial hypertension, tending to regress after APA management. Our longitudinal study (2-16 years) showed primary aldosteronism as a well curable, albeit rare, cause of hypertension. As regards BP and laboratory tests normalization, better results were achieved in surgical APA cases than in patients treated with spironolactone. Older age, longer history of hypertension and more frequent incidence of obesity, nephrosclerosis and pyelonephritis may be responsible for hypertension persisting after surgical treatment.

We report a case of bilateral metachronous xanthogranulomatous pyelonephritis (XGP) in a hemodialyzed patient with end-stage renal failure due to bilateral nephrolithiasis. The XGP was initially diagnosed by computed tomographic (CT) scan, and right nephrectomy was performed. The patient remained clinically stable for the next year. Involvement of the contralateral kidney was again confirmed by CT examination. Both kidneys showed histologic changes compatible with XGP. A coexisting nephrogenic adenoma of the bladder has been attributed to chronic urinary tract infection.

Three new cases of a rare benign proliferative lesion of the urothelium (nephrogenic adenoma) are hereby added to the existent 58 reported cases. All 3 lesions occurred in the bladder. Two of the 3 cases presented with a history of surgical interventions on the bladder, and the third patient had a history of chronic cystitis and pyelonephritis, and was on chronic dialysis. Diagnosis was made on histologic examination of cystoscopic biopsy of the lesions. Transurethral resection and/or fulguration was the treatment of choice. There was no recurrence of the lesions on follow-up cystoscopic examination.

Fever following operations on the vesical cervix was analysed in 167 patients, whereby the closing of the ostia was observed. Vesicoureteral reflux caused by lesion of the trigonal unit in the region of the inner vesical sphincter causes parenchymatous infection of the kidney to a lesser extent than expected. The specific conditions after the removal of an adenoma of the vesical cervix, with heavy bleeding, the necessity of urine drainage with all its weak points, the high level of bacteria in the urine combined with a delayed epithelization of the "inner wound" can be the starting point for a rise in temperature, whereby haematogenous pyelonephritis is of special significance. A decision on the expediency of antibiotic therapy should in any case only be made after obstructive and locally retentive processes have speedily been excluded as possible causes.

An etiological study on renal adenomas with specific references to dysplastic tubular lesions and adenocarcinomas was made, concentrating on histopathological and statistical surveys. Seventy-two unilateral kidneys obtained at random in autopsy cases were examined macro- amd microscopically on the consecutive sliced sections. Adenomas were found frequently in the cortex of 15 cases (20.8%), and particularly dysplastic tubular lesions were considerably associated with adenomas and detected even more frequently in 26 cases (36.2%), whereas fibromas in the medulla of 8 cases (11.1%). Most of the adenomas (86.7%) were found in nephrosclerotic kidneys; i.e., in vascular nephrosclerosis (53.4%), chronic pyelonephritis (13.3%), and in end-stage kidneys. The morphological feature of adenoma cells were also confirmed in the dysplastic tubular epithelial cells. These data imply that long-term renovascular and/or renostromal damages may induce dysplastic tubular lesions and further act as important enhancing or promoting factors on adult renal oncogenesis from the cortical tubular epithelium.
