A clinical observation was made on 261 cases of transurethral resection of benign prostatic hyperplasia (TURP) by the same operator, admitted during the period of 10 years from January 1984 to December 1993. The objective cases were divided by every 50 cases into 5 groups, and the operation results were compared in each group respectively. The results showed the tendency of increasing weight of resected prostatic tissue and decreasing operating time, consumed time for the resection of l gm of prostatic tissue, blood loss during operation, duration of postoperative gross hematuria and incidence of postoperatively complicated cases, as experiencing more TURP cases. The operation results were markedly improved and stabilized after experience of 150 cases of TURP. Our study suggests that TUR technique of the operator is improving step by step by accumulating experiences of TURP and the expert and stabilized skillful technique will be achieved after experience of more than 150 cases of TURP but the improvement of TUR technique may be accelerated by aid of better TUR instrument and teaching system.

Clinical significance of flow cytometric DNA ploidy and proliferating cell nuclear anrigen (PCNA) was evaluated in terms of clinical stage. histological grade and tumor markers. using the materials obtained from paraffin embedded blocks of 47 patients with prostatic adenocarcinoma. The incidence of DNA aneuploidy in total population was 51.1 %. Although no significant correlation between histological grade or clinical stage and DNA ploidy pattern was demonstrated, the frequency or aneuploidy was shown to increase as the poorer the histological grade and the higher the clinical stage. All patients in aneuploidy group and 66.7% of the patients in diploidy group had PSA levels of more than 4ng/ml, and 57.1% of those in aneuploidy group and 50% of those in diploidy group had PAP levels of more than 3.2ng/mI. Overall, the difference in survival curves for diploidy and aneuploidy group was not significant. But. in patients of stage D with intermediate histological grade, the survival difference between diploid and aneuploidy tumors was obvious. The PCNA related proliferating index was significantly increased with the progression of the clinical stage. And the proliferating index was inversely related to the degree of glandular differentiation. but without statistical significance. Although proliferating index of prostatic adenocarcinoma didn`t have any significant correlation with the survival, the statistically significant difference was shown in survival between PCNA score+/-group and PCNA score + to +++ group.

Radiologic chain cystourethrography for stress urinary incontinence (SUI) has several disadvantages including the risk of excessive radiation, the time required for the test, and the discomfort of the patients. Nowadays it is widely accepted that transrectal ultrasonography for evaluating bladder and urethra provides similar information about SUI comparing with the conventional radiographic examination. We evaluated the effectiveness of transrectal ultrasonography in the diagnosis of SUI in 30 women with SUI and in normal 20 women as a control. The results of evaluation were as follows: 1. Mean age was 52.9 in SUI group and 48.5 in control group, and mean parity was 2.8 in SUI group and 3 In control group. 2. According to the symptom grading by Stamey, 8 patients (27%) were Grade I and 22 (73%) were Grade II. 3. The mean value of posterior urethrovesical angle (PUVA) at resting state was 139 +/- 14.7 degrees in control group and 145 +/- 15.2 degrees in SUI group (p>0.05). 4. The mean value of PUVA at strain state was 146 +/- 7.9 degrees in control group and 169 +/- 12.1 degrees in SUI group (p<0.05). 5, Bladder neck descent was 7.3 +/- 2.7 mm (mean+/-SD.) in control group and 13.7+/-6.2 mm in SUI group (p<0.05). 6. Diagnostic criteria of SUI in transrectal ultrasonography are more than 149.5 degrees in PUVA at strain state, and more than 9.1 millimeter in bladder neck descent. 7. Sensitivity and specificity of transrectal ultrasonography in the diagnosis of SUI were 86% and 80% in PUVA at strain state, 80% and 80% in bladder neck descent, respectively. 8. There was significant change of transrectal ultrasonographic finding in pre and post-bladder neck suspension (p<0.05). In conclusion, transrectal ultrasonography is simple, non-invasive, not shameful, and free of radiation, so might be a useful diagnostic method in female SUI.

BACKGROUND: Clinical and experimental studies have suggested that brain death may cause hemodynamic, electrocardiographic, functional or histopathologic changes of the heart. METHODS: Brain death was induced by increasing intracranial pressure(ICP) abruptly by intermittent bolus injection of saline(model ) or gradually by continuous infusion of saline(model ) to the epidural catheter in 5 mongrel dogs, respectively. Hemodynamic and biochemical changes during the process of brain death and histopathologic changes of the myocardium were analyzed and compared in two brain death models, and the association of apoptosis was also evaluated. RESULTS: 1) Two predominant subsets of acute contraction band lesion were produced in both brain death models : paradiscal and holocystic contraction band lesions. Both contraction band lesions were more prevalent in brain death model . 2) The frequency of both contraction band lesions was lowest in the epicardial layer and highest in the endocardial layer in both models, but no correlation was observed between the degree of contraction band lesions and ICP, LV maximum +dp/dt or catecholamine levels. There was no statistical difference between any of the LV circumferential blocks and either type of contraction band lesion, and transaxial distribution was not also different in both models. 3) There was no remarkable histopathologic changes in the analysis of major epicardial coronary arteries. Apoptotic cells were suggested in the scattered myocytes in the light microscopy and apoptosis was detected by in situ nick end labeling method. Electron microscopy revealed a condensation of nuclear chromatin and convolution of nuclear membrane in those myocytes. CONCLUSIONS: Myocardial changes due to brain were observed frequently, and few apoptotic cells were found in the brain death heart. Studies on the treatment strategy to minimize damages of myocardial structure and function caused by brain death should be followed in the near future.

PURPOSE: To investigate the efficacy of age, International Prostate Symptom Score(I-PSS), quality of life(QOL) score, various parameters obtained by transrectal ultrasonography(TRUS) as predictors of the onset of acute urinary retention in patients with benign prostatic hyperplasia(BPH). MATERIALS AND METHODS: From January 1996 to December 1997, 101 men(mean age 70years, range 52-92) with symptoms of BPH were enrolled in this study. Among them, 36 patients had suffered from acute urinary retention. TRUS was used to calculate the total prostate(TP) volume, the transitional zone(TZ) volume, the transitional zone index(TZ index=TZ volume/TP volume). To compare the usefulness of various indices, the area under the receiver-operator characteristic(ROC) curve was calculated for each index. RESULTS: There were significant differences in age, TP volume, TZ volume, TZ index between patients with and without acute urinary retention, but no significant differences in I-PSS and QOL score. In patients with acute urinary retention, the area under the ROC curve was 0.911 for the TZ index, 0.892 for the TZ volume, 0.769 for the TP volume and 0.660 for the age. CONCLUSIONS: The TZ index is a useful predictor of acute urinary retention in patients with BPH and may be a useful parameter for decision of surgical intervention.
