[Experiences with Depo-Provera (medroxyprogesterone) in the treatment of kidney tumors]. / Erfahrungen mit Depo-Provera (Medroxyprogesteron) bei der Behandlung von Nierentumoren.

30 patients with renal tumours were treated with Depo-Provera (Medroxyprogesterone). Among the 21 patients operated on without metastases and with an parallel metastasis (fibrous capsule, adipose capsule, peritoneum) in the course of 6 to 15 months no one died of a tumour progression. Among the 9 patients with a distant metastasis in one case the regression of the metastasis could be achieved, whereas in another case progesterone stopped the progression of the intraoperatively observed liver metastasis.

Resection in renal tumour patients.

Nine cases (two of them bilateral) of renal resections for renal tumour are reviewed. The survival results of patients with bilateral renal tumours are considered particularly favourable, one of them has survived for 72, the other for 37 months. Of the patients with solitary renal tumour, one was lost 25 months postoperatively, after the development of a distant metastasis. The other patient has been free of recurrence and metastases after 31 months. The above results have proved the outdatedness of the old concept, i.e. to remove the tumorous kidney. As supported by the authors' cases, their patients have had a high survival rate after resection for renal tumour. The clear-cell tumours are well demarcated by a fibrous capsule and they can easily be resected. The granular-cell renal tumours are localized more centrally, they often infiltrate the kidney. In cases cautiously considered, the resection of the tumorous kidney can be performed under the present technical conditions by strict 6 monthly postoperative urographic, ultrasound, and angiographic examinations.

[Prevention of pyelonephritis]. / Prophylaxe der Pyelonephritis.

The possibilities of the prophylaxis of pyelonephritis in the intrauterine life, in infancy and childhood, in internal medicine, gynaecology and urology are described. After explanation of the causes of pyelonephritis it is referred to the importance of the asymptomatic, significant bacteriuria and it is emphasized that there is no primary pyelonephritis, but every pyelonephritis is secondary.

[Hair loss following chronic hemodialysis]. / Haarausfall nach chronischer Hämodialyse.

Attention is drawn to the frequent occurrence of loss of hair in chronically dialysed patients. No examinations were undertaken to find the cause of this phenomenon. However it is possible that, besides insufficiently eliminated toxins, hypothyrosis is also involved.

[An operated case of bilateral kidney tumor]. / Operierter Fall eines zweiseitigen Nierentumors.

In a case of bilateral kidney tumour, contralateral tumour resection was performed after unilateral nephrectomy. One and a half years later the patient has no complaints. The importance of partial nephrectomy in such cases is stressed.

Real-time ultrasonography: a new tool for the intraoperative localization of renal calculi (preliminary communication).

A B-scan real-time ultrasonic equipment providing three-dimensional information was used for intraoperative localization of renal calculi. Simplicity, non-invasiveness and ability to demonstrate radiolucent calculi or matrix are stress as the main advantages of the method. Its current use on a larger scale is expected and regarded as desirable.

Ten years of diagnostic ultrasound in renal disease.

Observations with diagnostic ultrasound in renal disease over a 10-year period are reviewed. The advantages of diagnostic methods involving the least possible discomfort to the patient are emphasized. Ultrasonography is regarded as a reliable non-invasive method for the diagnostic differentiation between renal tumours and cysts. It was used by the authors for this purpose in 740 cases. Renal tumours were found by this method in 622, and renal cysts in 118 cases. Of the 740 patients, 726 underwent surgery. The preoperative ultrasonic diagnosis of renal tumour proved to be correct in 91.8 per cent, that of renal cyst in 88.9 per cent of the respective surgical cases. Ultrasonography also lends itself to the follow-up of polycystic disease of the kidney, being suited for its early diagnosis, as well as to its identification in the stage of renal failure when the traditional diagnostic methods are no longer practicable.

[Clinical value of immunologic studies in patients with bladder tumors]. / Der klinische Wert immunologischer Untersuchungen bei Patienten mit Blasentumoren.

By means of mathematical calculations the authors tried to find correlations between the clinical and histological stages of vesical tumours and the results of immunological tests. Density calculation showed what parameters follow the degrees of malignity. Moreover the significance of the chain and basic proportional factors of the parameters calculated for diagnosis and follow-up is pointed out.
