摘要:

This study has been carried out in order to investigate the effects of a standard oral calcium load in 18 hypercalciuric and 18 normocalciuric recurrent stone formers. Following oral loading there was not a significant difference in the two groups studied, as far as serum calcium increment was concerned; however, urinary calcium excretion was significantly greater in hypercalciuric stone formers. The results obtained, although they do not exclude the presence of intestinal calcium hyperabsorption, seem to demonstrate the existence of a diminution of renal tubular calcium reabsorption in patients with idiopathic hypercalciuria.

摘要:

38 pure and 11 mixed seminomas were studied with the peroxidase-anti-peroxidase method for the presence of chorionic gonadotropin (β-HCG) and pregnancy-specific β1-glycoprotein (SP1). HCG was found in 8 of 49 cases, SP1 in 5 of 49 cases in syncytial and mononuclear giant cells. The 5 pure seminomas with positive tumor markers appear to have no worse prognosis than pure seminomas without HCG or SP1 production. None of the seminomas was found to contain carcinoembryonic antigen or alpha-fetoprotein.

摘要:

85 patients with prostate cancer and 20 patients with benign prostatic hypertrophy underwent DNA single-cell fluorescence photometry to investigate the possibility of DNA-related automatic diagnosis and grading of prostate cancer. The DNA histograms were analysed statistically by univariate data description, stepwise linear discriminant analysis and regression analysis. The accuracy for the malignancy diagnosis was 85.1 %, with 10.6% false-negative and 4.3% false-positive results. The accuracy of the malignancy grading, however, was very poor with only 39.5%.

摘要:

The urodynamic consequences of renal autotransplantation and pyelocystostomy were studied in 17 male and 3 female patients. The indications of the procedure were urothelial tumor of the upper urinary tract, remaining outflow obstruction after conventional pyeloplasty and recurrent stones. The mean observation time was 31 months (range 3–50 months). The micturition flow rate was unchanged. There was an insignificant increase in residual urine. No evidence of any clinically significant disturbance of the sensory or motor bladder innervation or reduction of the functional bladder capacity was found. Urethrocystography showed transient dilatation of calyces at micturition. Urinary tract infections, when present, had the same pattern as preoperatively. Thus, autotransplantation of the kidney with a wide, direct pyelocystostomy is consistent with essentially normal urodynamics of the transplanted renal pelvis and the bladder.

摘要:

85 patients with adenocarcinoma of the kidney were operated in 1982 and 1983. 9 patients showed a tumor thrombus extending into the renal vena and vena cava. Ultrasound examination of the retroperitoneal cava up to the liver veins was always able to diagnose the tumor thrombus and its cranial extension. If the end of the thrombus was visualised ultrasonographically below the diaphragma and confluence of the liver veins into the cava, no additional diagnostic procedure except intravenous urography was found to be necessary for planning operative treatment. Arteriography, cavography and computer scanning did not give additional information important for surgical intervention.

摘要:

Urinoma as a presenting sign of carcinoma of the bladder, as occurred in this case, is rare. Aspiration of the cystic mass under sonography and chemistry of the fluid confirmed the diagnosis. The inferior extension of the urinoma on CT scan confirmed the gradual fading of Gerota’s fascia into the retroperitoneum. Abdominal mass in the form of a urinoma is an uncommon presentation and only a few documented cases are reported in the literature. This case illustrates that the Gerota’s fascia fades inferiorly into the retroperitoneum.

摘要:

The tripeptidyl carboxypeptidase activity of angiotensin-converting enzyme (EC 3.4.15.1) has been determined in several human tissues of the urogenital tract. Benzoyl-glycyl-L-seryl-L-prolyl-L-phenylalanine was used as substrate. The cleaved benzoyl-glycine was measured by means of high-performance liquid chromatography. Results obtained showed a high enzymatic activity for seminal plasma, vesicula seminalis and benign prostatic hyperplasia. Normal prostate and in particular prostatic adenocarcinoma have low enzymatic activity. The activity of the enzyme is sensitive to inhibition by the angiotensin-converting enzyme inhibitor captopril.

摘要:

A clinical study of the adverse effects induced by the endocrine therapy with a high dose of estrogen in 45 patients with stage C or D prostatic carcinoma is conducted. Transient decreases of hemoglobin and serum protein values were observed after administration of estrogen. The levels of glutamine-oxaloacetic and glutamic-pyruvic transaminase showed a transient increase. The value of serum total cholesterol and electrolytes showed no changes. Serial evaluations of electrocardiograms have played a minor role in the observation of cardiovascular disease. Up to date we have not experienced cardiovascular death in our cases during the endocrine therapy.

摘要:

40 end-to-end anastomoses in dogs were made, partially under considerable tension, in the lower part of the ureter after transverse division and after resection of segments between 3 and 10 cm. In three operative modifications the influence of resection length, tension, and microsurgical technique on the function of anastomoses was examined. As an equivalent to tension the approximation distance of the ends of the ureter was measured after resection of segments. Controls prove the superiority of the microsurgical procedure. In our experiments the resection length lies far above the reported maximum resection length of 3–5 cm. The results are not dependent on the resection length. There is every reason to believe that even the tension that lies on the anastomosis is not very important for the results.
