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.

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.

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.

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.

Forty eight patients with cervical cancer underwent cystoscopy, computed tomography and transrectal and transvaginal ultrasonography. Transrectal ultrasonography was as accurate as computed tomography in the evaluation of the bladder wall invasion in cervical cancer. Most patients with bullous edema in cystoscopy appeared to have invasive lesions in transrectal ultrasonography. Transrectal ultrasonography was superior to transvaginal one in the evaluation of the posterior well of the bladder. In conclusion. transrectal ultrasonography is an another good diagnostic method for the evaluation of the bladder wall invasion in cervical cancer.

BACKGROUNDVirtual reality (VR) has been recognized as a useful modality in the training of surgical skills. With respect to basic endoscopic skill training of urology, we sought to investigate the effectiveness of the UroMentor(TM) virtual reality simulator (VRS) in the skill acquisition of flexible cystoscopy.

METHODSUrologists familiar with rigid cystoscopy procedures were selected to take part in a virtual training course of flexible cystoscopy. Changes in total operating time, frequency of injury, number of digital markers inside the bladder, and the global rating scale (GRS) scores were assessed following eight repeated training sessions on the UroMentor(TM).

RESULTSEighteen urologists voluntarily took part in the study. Total operating time was significantly lower after eight sessions of training by comparison ((111 ± 10) seconds and (511 ± 67) seconds, respectively; P < 0.001). Additionally, the frequency of injury decreased with training from (12 ± 2) times to (5 ± 1) times (P < 0.001), while the number of digital markers observed increased from 9 ± 0 to 10 ± 1 (P = 0.005). Finally, training with the UroMentor(TM) resulted in a GRS increase from (1.3 ± 0.2) points to (3.9 ± 0.2) points (P < 0.001).

CONCLUSIONthe VRS UroMentor(TM) can improve urologists' ability to perform flexible cystoscopy and could be used as an effective training tool for trainees.

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.

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.
