3.A Clinical Observation on Cystoscopic Manipulation of Distal Ureteral Stones with Dormia Stone Dislodger.
Korean Journal of Urology 1982;23(4):511-514
The cystoscopic manipulation was done in 52 cases of ureteral stones who visited the Department of Urology, Soon-Chun-Hyang College Hospital during the period of 18 months from May. 1979 to August. 1980 using Dormia stone disloger and the following results were obtained. 1. With the Dormia stone dislodger, 27 cases of ureteral stone were removed successfully. 2. The ureteral stone passed in 8 cases within 72 hours after manipulation. 3. Of the 27 cases, 2 cases were middle ureteral stone and 25 cases were lower ureteral stone. 4. The largest stone measured 6.5 x 13 mm. 5. There were no major complication but minor complication occurred such as fever, pain and gross hematuria.

4.The value of diagnostic cystoscopy in early detection of ureteral injury at the time of total laparoscopic hysterectomy (TLH).
Korean Journal of Obstetrics and Gynecology 2007;50(8):1125-1131
OBJECTIVE: To estimate the effect of diagnostic cystoscopy in early detection of ureteral injury at the time of total laparoscopic hysterectomy. METHODS: Retrospectively 598 women who received total laparoscopic hysterectomy from August 2004 to August 2006 were included. They were divided into two groups : no cystoscopic examination (n=398) group (Group A) and routine intraoperative diagnostic cystoscopic examination after intravenous indigo-carmine injection (n=200) group (Group B). The rates of ureteral injury after total laparoscopic hysterectomy were compared between both groups. RESULTS: Postoperative ureteral injury was observed in 3 case of Group A (3/398 : 0.75%) and in no case of Group B. In 2 cases of group B (2/200 : 1.00%), Intraoperative ureteral injury was detected by cystoscopy. CONCLUSION: Routine intraoperative diagnostic cystoscopy allows for early recognition and treatment of obstructive ureteral injuries, and reduces the rate of late postoperative ureteral complications during advanced laparoscopic procedures.

The need for film recording in endoscopic practice is important with the present demand for documentation and teaching (legal problem). The electronic endoscopy which has a very small charge coupled device (CCD) at the distal end of an endoscope yields several times more resolving power than conventional optical endoscopes. However the system has not been utilized in Urologic field because there has not enough space for CCD at the end of the telescope comparing to the endoscope in Gastroenterology field. However the video converter with CCD could be adapted to the eyepiece of the telescope, and the automatic monitor photo unit (CVP 600, SAMSUNG, KOREA), video system and monitor were used for imaging, which is so called Urologic Video Information System (UV1S). The image processing was done by instantaneous system (CCD color camera, EC-202 II, ELMO, Japan) with conventional optical light source. From September 1992 to August 1996, we did cystoscopic examination with CCD in 1079 cases.

Recently, primary ureteral tumors are more frequently reported in urological field even though considered as rare. We have observed a case of primary ureteral tumor confirmed with the cystoscopy and retrograde pyeloureterogram. Choice of operation is nephro-ureterectomy with removal of a cuff of bladder wall around the ureteral orifice. It is necessary for a physician to make the early diagnosis and removal of the tumor as soon as possible.

7.Clinical Evaluation of the BTA TRAK assay and Comparison with Voided urine Cytology in Patients with Bladder Cancer.
Korean Journal of Urology 2001;42(1):47-50
PURPOSE: The purpose of this study was to evaluate the clinical performance of the BTA TRAK assay and to compare it with that of voided urine cytology in the detection of bladder cancer. MATERIALS AND METHODS: TRAK was evaluated two groups of patients. Bladder cancer group was comprised of patients wit histologically confirmed active bladder cancer. The second group of patients had a history of bladder cancers but were considered to have no evidence of disease on basis of cystoscopic evaluation of bladder and/or biopsy. Sensitivity was determined in urine samples from patients with histologically confirmed bladder cancer. Specificity was determined in samples from patients who had a history of bladder cancer but no current evidence of disease. RESULTS: BTA TRAK assay was positive in 21 of 24 samples from patients with diagnosed bladder cancer. The sensitivity of BTA TRAK assay (87.5%) was significantly higher than that of voided urine cytology (45.8%). According to grade, the sensitivity of BTA TRAK assay was significantly higher than that of voided urine cytology in urine samples from patients with grade 1 bladder cancer. The specificity of BTA TRAK assay was 80% in patients who had a history of bladder cancer but no current evidence of disease. CONCLUSIONS: The BTA TRAK assay is superior to voided urine cytology in the detection of bladder cancer. The difference of the sensitivity was statistically significant(p<0.05). The results of this study indicate that BTA TRAK assay is a useful adjunct to cystoscopy in the detection of bladder cancer and useful monitoring tool of bladder cancer.

8.Values of Urine Cytology in the Diagnosis of Urothelial Carcinomas.
Korean Journal of Urology 1982;23(8):1062-1066
In order to determine its accuracy the authors conducted cytologic examination on patients found to have urothelial carcinoma by cystoscopy, histopathologic and radiological examinations at the Department of Urology, Catholic Medical College, from January 1971 to August 1981. The results were as follows: 1. Age distribution of the urothelial carcinomas is from 33 to 80 years age and the most frequent age group is 40 to 59 years age. The male: female ratio is 4.3:1. 2. Of the 32 patients, 4 cases (12.4%) were negative, 14 (43.8%) suspicious and 14 (43.8%) positive reports. 3. No significant correlations were found between the urine cytology and histologic grade, but the higher cytologic class had tendency to have the higher histologic grade. 4. In the aspect of the tumor size and cytology, large sized tumor had showed positive findings more frequently than that of, smaller one, but it showed high accuracy rate (77.8%) when small sized tumors were multiple.

Urothelial neoplasms in patients younger than 20 years old are extremely rare, and there is no established etiology, treatment guidelines, or surveillance for urothelial carcinoma in the pediatric population. A 17-year-old boy who presented with gross hematuria showed a smooth, round mass on the left lateral wall of the urinary bladder on cystoscopy. Histologic examination showed low grade papillary urothelial carcinoma of the urinary bladder without muscle layer invasion. We report a case of papillary urothelial carcinoma of the urinary bladder in a pediatric patient treated with transurethral resection.

PURPOSE: Asymptomatic microscopic hematuria is a difficult problem faced at the offices of many urologists. This study was aimed at evaluating the ability for the detection of significant lesions, according to the grade of microscopic hematuria and the comparison of various diagnostic modalities. MATERIALS AND METHODS: Between March 1999 and December 2003, 755 adult patients that visited our hospital due to asymptomatic microscopic hematuria were examined according to the diagnostic algorithm. The male-to-female ratio was approximately 1:1.1 (366:389). Microscopic hematuria was divided into five grades. Lesions found at evaluation were categorized as either highly or moderately significant or insignificant lesions. RESULTS: 221 (29.3%) out of 755 patients were found to have lesions during evaluation. Of these 221 patients, 33 with highly significant lesions, including 4 urologic malignancies, 127 with moderately significant lesions and 61 with insignificant lesions, were detected. Correlation was shown between the degree of microscopic hematuria and the likelihood of detecting significant urologic diseases. The sensitivity and specificity for the detection of significant lesions by urine cytology, ultrasonography (USG), intravenous pyelography (IVP), cystoscopy, computed tomography (CT) and the combination of USG and IVP were 2.5/96.3%, 35.6/96.5%, 34.7/ 96.0%, 7.4/97.7%, 100/98.2% and 44.8/94.8%, respectively. CONCLUSIONS: The combination of USG and IVP for the detection of significant lesions at the initial examination was more beneficial than USG or IVP. Cystoscopy and CT are necessary additional diagnostic modalities for patients with abnormal findings at the initial examination and for those patients with asymptomatic microscopic hematuria who are at high risk.
