摘要:
The plasminogen activation system is considered to play an important role in cancer growth and metastasis. Both plasminogen activators (PAs) and their fast-acting inhibitors are produced in tumor cells and their surrounding tissues. In order to clarify the influence of the existence of malignant tumor in urinary tract on the systemic fibrinolytic activity, we designed a study in which we compared the plasma levels of PAs and their inhibitors between before and after radical resection of tumors. Fourteen patients with renal cell carcinoma and 14 patients with transitional cell carcinoma participated in the study. In both groups, plasma levels of tissue-type plasminogen activator and urokinase-type plasminogen activator before the operation were higher than those 15 days after operation. The plasma level of plasminogen activator inhibitor 1 (PAI-1), however, did not change after the operation in the renal cell carcinoma group, and it decreased slightly in the transitional cell carcinoma group although it was not significant. When these values of the groups with or without metastasis were compared to other organs or lymph nodes, the PAI-1 level before operation was significantly higher in the group with metastasis than that without metastasis. In the three groups divided by the degree of atypia, PAI-1 level in the most atypical group was the highest. These results suggest that the fibrinolytic system in the plasma of cancer patients may play an important role in tumor growth and metastasis.

摘要:
Epidermal growth factor (EGF) content in seminal plasma of 17 patients with androgen deficiency (12 Klinefelter’s syndrome and 5 hypogonadotropic hypogonadism) was determined before and after hormone replacement. No significant increase of plasma testosterone level was demonstrated after testosterone administration in Klinefelter’s syndrome, although the level in 4 of 5 patients with hypogonadotropic hypogonadism reached the normal range. In 16 patients, except 1 with hypogonadotropic hypogonadism with no increase of blood testosterone level, prostate volume increased after hormone therapy, and volumes after treatment were significantly larger than those before treatment. On the other hand, EGF concentration in seminal plasma remained at the pretreatment level in most patients. It is therefore concluded that although the prostate volume increases to almost normal after treatment, prostate function does not improve in most patients, indicating that in patients with hypogonadotropic hypogonadism fertility potential may remain low, even if they obtain normal seminal parameters after treatm

摘要:
One metabolic pathway for glycine leads to glyoxylate which is the precursor of oxalate. To investigate whether absorption of glycine solution in transurethral operations may promote precipitation of calcium oxalate stones, we collected urine for 24 h before and after an intravenous infusion of 22 g of glycine in 10 male volunteers. There were no significant changes in the urinary excretion of oxalate, calcium, or citrate. Urine volume and amino acid excretion increased, while the urine contained less potassium. These results provide no biochemical evidence of an increased risk of renal lithiasis due to glycine irrigation during transurethral operations.

摘要:
336 patients with urinary calculi were treated between June 1988 and October 1991 with extracorporeal shock wave lithotripsy using the Dornier MPL 9000 lithotriptor. Of 352 renal units (a kidney and its ureter), 286 had renal stones, 62 had ureteral stones and 10 had both. There were radiolucent stones in 6 units. The complete disintegration rate was 94%. The mean number of shock waves was 2,973, the range being from 300 to 16,131. In 310 of 447 (64%) sessions, treatment was done without any anesthesia. The rate of complete removal was 67.3% 3 months after the last treatment. Only 11 patients required supplementary treatment consisting of percutaneous nephrolithotripsy and transurethral lithotripsy. There were no severe complications except subcapsular hematomas observed in 2 patients. The Dornier MPL 9000 is a useful lithotriptor for the treatment of urinary calculi, except stag-horn calculi.

摘要:
Urinary risk factors and inhibiting factors for urolithiasis, such as oxalate, calcium, phosphate, uric acid, citrate, and magnesium, were examined in 12 patients receiving continent urinary diversion, neobladder, or augmentation cystoplasty using intestine. These data were compared with the incidence of pouch stone formation. Ten (83.3%) of 12 patients had at least one risk factor, and 5 (41.7%) of 12 had two or more risk factors. Pouch stone developed in 4 (80%) of 5 patients with two or more risk factors, and in none of 7 patients with one or zero risk factors. The incidence of pouch stone in the former group was significantly higher than in the latter group. These results suggest that urinary reservoir operations should not be performed in patients with two or more risk factors for urolithiasis.

摘要:
Five urinary bladder incisions were performed in 16 rabbits and the defects closed by plain catgut 4-0, chromic catgut 4-0, polypropylene 4-0, polyglactin 910 4-0 and polyglactin 910 8-0 in the form of an all-layer suture, thereby obtaining a total of 80 suture sites. The running sutures in 8 animals were reviewed by light microscopy after 1, 2, 7 and 15 weeks, and in 8 additional animals after 3 days, 1,2,7 and 15 weeks by scanning electron microscopy. Moreover, we analyzed and compared the autopsy findings on gross inspection, the urinary sediments and urinary cultures of the individual animals. Scanning electron-microscopic evaluations showed that epithelization of the intraluminal suture portions can be accomplished after 3 days already. Reduced suture strength and rapid absorption of the suture material prevent later postoperative incrustations. Light-microscopic inspection of the segments of the bladder wall bearing this suture material suggests that a minor inflammatory tissue response around the suture material – with polyglactin 910 8-0 in particular – is more likely to enhance regeneration of the tunica muscularis and to prevent formation of cysts than seen with a long-standing highly inflammatory tissue response around the suture site of catgut threads. In the animal experiment, the polyglactin 910 suture has shown sufficient firmness and proved to be superior to any other suture material as regards the reaction to foreign bodies and inclination to incrustation. A thinner thread used for sutures in the efferent urinary tract would thus have to be given preference over others. Plain catgut, chromic catgut and polyglactin 910 sutures, 4-0 in strength, were found to be disadvantageous in the animal model. The nonabsorbable propylene thread turned out to be inadequate in urinary bladder surg

摘要:
This study presents data on HLA phenotypes of 52 unrelated patients suffering from idiopathic Peyronie’s disease. This first investigation on HLA class II antigens detected an association of HLA-DR3 and -DQw2 in this disorder. HLA typing was done from ACD-stabilized peripheral blood using the modified lymphocytotoxicity test. Antigen frequencies of the patient group were compared with those of healthy individuals of the local population. There were no deviations of frequencies for antigens of the B7 cross-reacting group as described in earlier studies. In addition none of the other class I antigens (HLA-A, -B, -C) showed any significant deviation in frequencies after correction of p values. Regarding class II antigens HLA-DR3 was detected in the patient group in 33.3% compared with 16.0% of the control population (corrected p < 0.05). The closely linked antigen DQw2 was found in 58.8 compared with 31.2% (corrected p < 0.005). Not only genetic factors can be stated by these findings. As HLA-DR3 and -DQw2 are known to be the typical associated antigens of organospecific autoimmune disorders, this suggests possible autoimmunological factors in this disorder of otherwise unknown etiolog

摘要:
Spontaneous rupture of the urinary bladder is a rare entity. This is, in part, the cause for the low rate of correct preoperative diagnosis, the high rate of delayed diagnosis, morbidity and mortality. We report a case of spontaneous rupture of the urinary bladder in an adult patient, complicated by extensive fascitis of the abdominal wall. The stormy course and long hospitalization in the case described are characteristic of patients with spontaneous bladder rupture and warrant a high index of suspicion in order to achieve an early diagnosis.

摘要:
Two cases of colorenocutaneous fistula due to genitourinary tuberculosis are presented. They were successfully managed by single-stage surgery (nephrour-eterectomy, fistulectomy, and primary repair of the colon) and antitubercular treatment. The literature is briefly reviewed.
