[Improved interpretation of renal-vein-renin-ratio by simultaneous determination of renal 131I-hippuric-acid-clearance-ratio in patients with renovascular hypertension (author's transl)].

In patients with unilateral vascular kidney disease and hypertension, ratio of renal-vein-renin was compared with 131I-Hippuric-acid clearance and change in blood pressure during Saralasininfusion. The ratio of renal-vein-renin was positively correlated with the ratio in renal plasma flow between the kidneys in all patients studied. The ratio of renins therefore is a result of two factors: The difference in renin secretion and the difference in blood flow in the two kidneys. In patients with angiotensin independent hypertension renin-ratios up to 2.0 were found without relevance to elevated blood pressure. When the difference in renal blood flow between both kidneys was small, even a slight difference in renal vein renin indicated hypertension related to increased renin secretion. Renin-ratios in the critical range between 1.5 and 2.5 should only be interpreted in respect to a similar ratio in renal blood flow.

[Early diagnosis of cancer of the prostate by rectal palpation (author's transl)].

Transrectal biopsy was performed on 173 unselected patients, aged 45-85 years, with disease of the prostate, who had previously had a screening examination. The findings on palpation by the referring doctor and the authors' own assessment were compared with the histological findings. Of 37 histologically confirmed cases of carcinoma of the prostate 16 (44%) had been correctly diagnosed by the referring doctor and 28 (76%) after examination at hospital. On the other hand, of 136 histologically negative cases the referring doctor's diagnosis had been correct in 112 (81%) instances and at hospital 94 (69%).

[Cholesteatoma of the renal pelvis (author's transl)].

A 63-year-old male experienced pain in the epigastric region and a septic fiver. X-ray examinations showed a tumor-like process in the lower part of the left kidney with some concrements. Upon operation a nodular inflammatory tumor was found, occupying more than two-thirds of the left kidney. Histologic examination revealed a typical cholesteatoma of the renal pelvis and calyces with some concrements among the abundant keratin material.

[Adrenal gland cysts. Case reports and potential complications--review of the literature (author's transl)].

Adrenal cysts are rare, mostly harmless, processes, either congenital inborn or acquired by regression, bleeding, infection and tumor. In the case of endocrine dysfunction with arterial hypertension and local expansion with perforation into the retroperitoneal, peritoneal and pleural cavity, purulence, bleeding and vasal obstruction complications are serious. In the differential diagnosis carcinoma of the kidney and the adrenal gland should be excluded.

[Macrohematuria associated with ruptured abdominal aneurysm (author's transl)].

Macrohematuria associated with rupture abdominal aneurysm is caused by renal infarction due to renal arterial compression or dissection, by renal congestion due to renal venous perforation, by urinary bladder congestion due to aortocaval fistula, possibly by hydronephrosis due to ureteral obstruction, and by urinary bladder perforation. Also in the case of a simultaneous urologic finding treatment of the aneurysm is urgent.
