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.

We report the results of field operation of TELEACE system between Kyung-Pook National University Hospital and Ul-Jin Goon Health Care Medical Center from December, 1990 to September, 1991, which had been operated as a kind of Integrated Services Digital Nework projects by KOREA TELECOMMUNICATION Inc. Ul-Jin Goon Health Care Medical Center transmitted 414 plain radiographs to our hospital in speed of 9600BPS. Each image was composed of 1024X1024 pixelsX8 bits/pixel. In our hospital, the image files were displayed on high resolution monitor (1280×1024 pixets). Text files of image interpretations were transmitted to the health care medical center. The two radiologists who had interpreted the transmitted images, went to the health care medical center and read radiographic film with blind test method. We obtained the following results: false negative rate of 6.3%, false postitve rate of 2.4%, mean sensitivity of 81.4%, mean specificity of 96.3%, and mean accuracy of 91.3%. In predictive value of 0.05, there was no significant difference between results of these two types of radiographs. In conclusion, TELEACE system was valuable to the clinicians isolated from services of radiologists.

Tissues obtained by transurethral prostatectomies were evaluated histologically and correlated with the clinical findings and the transrectal ultrasonographic pictures of 104 patients with benign prostatic hyperplasia (BPH). The patients were divided into 3 groups according to the following histology. predominantly glandular types (30 patients), predominantly stromal types (35 patients) and mixed types which have equal proportions of glandular and stromal hyperplasia (39 patients). The average age was highest in the glandular group. Postoperative obstructive symptom scores were significantly lower in the stromal type as compared to the glandular and the mixed type. The maximal flow rates at three months following the operations were highest in the stromal type. In comparison of the histologic findings with preoperative transrectal echographic pictures, the transverse and the longitudinal diameter of the transitional zone were significantly lower in the stromal type than in the glandular and the mixed type. The weight of transitional zone was significantly smaller in the stromal type than in the glandular and the mixed type. The echogenicity showed hyperechoic and isoechoic pattern in the stromal and the mixed type and hypoechoic and isoechoic pattern in the glandular type. The echographic homogeneity, the frequency of prostatic calculi and cyst formation, and the margination of the transitional zone did not show any significant difference among each group. In conclusion, the histologic types of BPH have correlations with the clinical findings and the transrectal ultrasonographic pictures. Furthermore precise interpretation of the histologic types of BPH by transrectal ultrasonography will be helpful in decision making about the treatment modality and in prediction of the clinical progress after some treatment for the patients with BPH.

PURPOSE: There are ample experimental and clinical data showing that if the bladder does not receive a significant urine input for a prolonged period it suffers a reduction in capacity and develops hypertonicity. We investigated the urodynamic changes before and after renal transplantation in the patients of chronic renal failure(CRF) under dialysis. MATERIALS AND METHODS: Urodynamic evaluations were performed in 47 CRF patients(25 males and 22 females, average age : 39 years) prior to renal transplantation and 4 weeks after renal transplantation. The clinical notes of each of the patients were reviewed to ascertain the cause of renal failure, duration and type of dialysis. RESULTS: The maximal flow rate , voiding volume, voiding time, volume of first sensation of fullness and the volume of urge sense were abnormally low in the patients of CRF, and the degree of deterioration was more remarkable in the patients of longer duration of dialysis, but the voiding detrusor pressure was within normal range in the patients of CRF irrespective of duration and type of dialysis. The maximal flow rate, voiding volume, voiding time, volume of first sensation of fullness and the volume of urge sense were increased significantly after successful renal transplantation, but the change of voiding detrusor pressure was not significant. CONCLUSIONS: The bladder capacity of CRF patients under dialysis is decreased to physiologic disuse state because of decreased urine input into the bladder for a prolonged period, but the contractility is well preserved irrespective of duration of dialysis, and the bladder capacity is recovered in the course of time after successful renal transplantation.

Until recently almost exclusively clinicochemical urine parameters have been used to determine the risk of urinary stone formation, because the urinary stone disease is considered as one of metabolic disorders. But the morpholgy of renal pelvocalyceal system also affects on the formation of stone particle and its growth, mainly by establishing urinary stasis. We reviewed 163 excretory urograms retrospectively, and pelvocalyceal systems of healthy persons and urinary stone formers were compared with regard to their morphology. In summary of the study, the majority of pelvocalyceal systems of urinary stone formers showed (1) an increased number of papillae; (2) a greater cranial and caudal exlension of pelvocalyceal sysrem:(3) an increased circular radius of the pelvocalyceal system and hence an increased pelvocalyceal system volume ;(4) an increased pelvic area, especially an enlarged total calyx area and hence a larger total area. (5) a higher degree of ramification and a higher number of branches in the calyx groups ; (6) a more sharp angle between the most caudally situated calyx neck and the direction of pelvic outlet :(7) a highly situated origin or the ureter more frequently ;(8) more frequent ampullary patterns of pelvocalyceal system. But the number of major calyx, the total calyx angle and the angle between the direction of pelvic outlet and the main direction of the ureter showed no statistically significant difference between the urinary stone formers and the healthy persons. The results indicate that the study on the morphology of the renal pelvocalyceal system by excretory urography may be used as a screening test to determine the risk of urinary stone formation.
