PURPOSE: While performing clean intermittent catheterization(CIC), atraumatic and non-infecting techniques are important in preventing long-term complications secondary to CIC. The aim of this study is to characterize several essential technical aspects of CIC in patients with neurologically stable spinal cord injury or diseases(SCI/D). MATERIALS AND METHODS: Between July 2002 and March 2003, a prospective questionnaire survey was undertaken in 106 neurologically stable SCI/D patients who were performing CIC as primary bladder emptying methods. Structured questionnaire was administered with the interview. Questionnaire items included key technical CIC steps and related questions. RESULTS: Mean age of the patients(74 males and 32 females) were 35.9(+/-1.3, SE) years and the duration of CIC was 17.3(+/-2.3) months. Levels of SCI/D were: cervical in 45 patients(42.4%), followed by thoracic in 43(40.6%), lumbar in 16(15.1%), and sacral in 2(1.9%). Omitting hand washing before CIC was found in 16 patients(15.1%), meatal cleansing before CIC in 13(12.3%), using lubricants in 12(11.3%), and performing CIC as a timed basis in 36(34.0%). The most preferred posture to perform CIC were: sitting(63.0%), followed by lying(19.1%) and standing(14.6%) in men, while sitting(45.6%), followed by the squatting(33.3%) and lying(15.8%) in women. Majority of the patients performed CIC five times a day with spending about ten minutes for each CIC. Omitting key elements were not significantly associated with the sex, age, level of SCI/D, duration of CIC, level of education, socioeconomic status. However, omitting meatal cleaning before CIC were significantly associated with the patients with shorter duration of performing CIC, lower educational level, and lower socioeconomic status(p<0.05). 57.6% of the patients were satisfied with the current CIC methods. CONCLUSION: Our results showed that some patients do omit key elements of the CIC steps. These elements should be emphasized during the initial CIC education and also must be screened during long-term followup in the SCI/D patients performing CIC.

PURPOSE: We evaluated the long-term outcomes of the tension-free vaginal tape (TVT) procedure for the treatment of female urinary incontinence (UI). MATERIALS AND METHODS: We included 141 patients who underwent the TVT procedure for UI and responded to a questionnaire at the 6-year follow-up. The questionnaire included selected questions of the Korean version of the Bristol Female Lower Urinary Tract Symptom (BFLUTS) questionnaire and questions on patients' satisfaction with the procedure. Subjects were characterized as having been cured if they answered 'never' to the questions about any episodes of urine leakage. RESULTS: The mean follow-up was 85.5 months. The overall long-term cure rate for UI was 83.0% with a satisfaction rate of 80.1%, whereas the 1-year cure rate was 93.4%. The 1-year vs. 6-year cure rates in patients with urodynamic stress UI (SUI group; n=107) and with mixed UI (MUI group; n=34) were 94.1% vs. 84.1% and 89.8% vs. 79.4%, respectively, with no significant difference between the two groups. Also, long-term satisfaction rates in the SUI and MUI groups were 83.2% and 70.6%, without a significant difference between the two. In the MUI group, the 1-year and 6-year cure rates of urgency UI were 81.9% and 58.8%, respectively. There were no serious long-term complications related to the procedure. Most patients (85.9%) would likely recommend the TVT procedure to others. CONCLUSIONS: After 6 years of follow-up, the TVT procedure showed a somewhat decreased cure rate for the treatment of female UI. However, most patients were satisfied with the procedure.

PURPOSE: To assess the usefulness of breath-hold fast MR imaging of liver with fat suppression (FS) by application of chemical saturation technique in the diagnosis of regional fatty changed suspected in sonography. MATERIALS AND METHODS: Thirteen patients who had focal lesions with diffuse, homogeneous signal changes after FS through chemical saturation technique without additional changes of imaging parameter during MR imaging of liver were selected. T1-weighed fast low-angle shot and T2-weighted turbo spin-echo sequences were obtained with or without FS during each single breath-holding session. Subjective changes of signal intensity between the pre-FS and the FS images were compared with the sonographic findings in each lesion. RESULTS: Seven lesions of decreased signal intensity after FS on T1 or T2-weighted images, including three lesions only at FS T1 images, were regarded as focal fat infiltration. All seven lesions had compatible sonographic findings as homogenously echogenic areas. Another six lesions of subjectively increased signal intensity including two lesions only at FS T2 images were regarded as focal fat sparing. All six lesions had sonographic findings as homogenous echo poor areas suggesting focal fat sparing. In cases regarded as fat infiltration, score changes were more prominent at FS T1 images than FS T2 images(p=0.0002). In cases regarded as fat sparing, score changes were more prominent at FS T2 images than FS T1 images(p=0.042). CONCLUSION: Breath-hold fast T1 and T2-weighted MR imaging with and without chemical saturation pre-pulse may be sufficient for characterization of regional fatty changes in the different ferential diagnosis of focal hepatic lesion found at sonography.

PURPOSE: With the aim of objectively assessing the symptoms' severity and treatment outcomes of urinary incontinence in the Korean population, the King's Health Questionnaire (KHQ) instrument was translated into Korean, with subsequent linguistic validation. MATERIALS AND METHODS: Between May 2002 and December 2002, two bilinguists independently translated the original English version of the KHQ into written Korean. A panel consisting of the aforementioned translators and three authors (SJO, HGP and SHP) reviewed the translations to form a single reconciled forward translation of the Korean version. Another bilingual translator, who had never seen the original KHQ, translated the draft Korean version of the KHQ back into English and subsequently assessed for equivalence to the original. Discrepancies between the original English form and the first draft Korean translation were reviewed by the panel. Cognitive debriefing interviews with five incontinent patients were performed to test the interpretation of the translation. A summary of the changes from the patient interviews were then reflected in the final Korean version. The document was finally proofread to check the spelling, grammar, layout and formatting. RESULTS: The multi-step process of forward translation, reconciliation, back-translation, cognitive debriefing and proofreading of the Korean version of the KHQ was completed. Conclusions: Translation and linguistic validation of the Korean version of the KHQ instrument were completed. Further tests for its psychometric performance will be required.

PURPOSE: Percutaneous fine needle aspiration biopsy is known to be a useful diagnostic method for the diagnosis of various pulmonary diseases. Its diagnostic yield is high, and it is safe, but complications such as pneumothorax can occasionally occur. We reviewed the complications arising after needle aspiration biopsy and analyzed the risk factors of pneumothorax. MATERIALS AND METHODS: The medical records and radiographic studies of 157 patients with various pulmonary diseases who underwent needle aspiration biopsy of the lung between 1990 and 1996 were retrospectively reviewed. The clinical features, treatment, and courses of complications were reviewed, and risk factors of pneumothorax such as depth and size of lesion, diameter of needle, number of punctures, and obstructive pulmonary abnormalities were analyzed. RESULTS: Complications occurred in 40 of 157 cases (25.5%), namely pneumothorax in 26 (16.6%), hemoptysis in 11 (7%), hemothorax in two (1.3%), and recurrence of malignancy at the site of aspiration in one (0.6%). When the patients were divided into three groups according to depth of lesion, there were significant difference in the incidence of pneumothorax ; the results were as follows : less than 2cm, 12.9% ; between 2 and 4cm, 24.1% ; and larger than 4cm, 57.1% (p<0.05). In pulmonary function testing, FVC (forced vital capacity) of patients with pneumothorax was less than that of patients without (2.6+/-0.9L vs 3.1+/-0.8L, p<0.05), but FEV1 (forced expiratory volume in 1 second), FEV 1% (percentage of predicted FEV1), FEV1/FVC,and FVC%(percentage of predicted FVC) were not different between the two groups. The incidence of pneumothorax in patients with pleura-attached lesion (9%) was lower than that of those with non-attached lesion (26%, p=0.01). The age of patients, size of lesion, diameter of the needle, guidance methods and number of aspirations showed no significant relationship with pneumothorax. CONCLUSION: In needle aspiration biopsy of the lung, depth of lesion and passage of a needle through aerated lung are significant risk factors of pneumothorax.

PURPOSE: Patient-relevant outcomes are increasingly used as complementary evidence of effectiveness in the evaluation of treatment options. With the aim of utilization in objectively assessing the symptom's severity and the treatment outcomes of urinary incontinence in Korean population, we translated the Incontinence Quality of Life(I-QoL) instrument into Korean version which subsequently was linguistically validated. MATERIAL, METHODS AND RESULTS: Our study lasted for a period of about 8 months, between November 2001 and June 2002. Two native Koreans speakers, who were also fluent in English, translated the original U.S. English I-QoL into written Korean independently. A panel consisting of aforementioned translators and three bilingual authors reviewed the translations to form a single reconciled forward translation of the Korean I-QoL. Another translator, who had never seen the original I-QoL, back-translated this first draft to English. The back-translation was assessed for equivalence to the original by the Health Research Associates, Inc. (HRA). Discrepancies between the original U.S.-English form and the first draft Korean translation were reviewed by the panel. Cognitive debriefing interviews with five incontinent patients to test the interpretation of the translation were made. Summary of the changes was set to the HRA and the comments from patient interviews were then reflected in the final Korean version. Comparison of the Korean version of I-QoL with the original I-QoL was made to ensure conceptual equivalence during a meeting with professional translators representing many counties involved. Finally, it was proofread to check spelling, grammar, layout and formatting. CONCLUSION: Linguistic validation of Korean version of incontinence measure I-QoL was completed and was internationally approved. It is now ready to use in Korea and further test for psychometric performance of the Korean I-QoL is need.

PURPOSE: The objective of this study was to achieve a linguistic adaptation of the original version of the Pelvic Pain and Urgency/Frequency (PUF) Patient Symptom Scale into Korean. MATERIALS AND METHODS: Between June 2008 and December 2008, a linguistic adaptation was carried out by 2 native Korean speakers who were also fluent in English. First, the original English version of the PUF was translated into Korean. A panel, which included the 2 translators, reviewed the translations to form a single reconciled forward translation of the Korean version. Then, another bilingual translator, having never seen the original version, back-translated the first draft of the Korean version of the PUF into English, and this back-translation was subsequently assessed for equivalence to the original. The panel discussed all discrepancies and produced a second version. After revising the 2nd version, 10 participants [5 interstitial cystitis (IC) patients and 5 persons from the general population], stratified variously by age, sex, and educational level, answered the PUF and were systematically debriefed afterwards. A summary of the changes from the patient interviews were incorporated into the third version. After the spelling, grammar, layout, and formatting were checked, the third version was verified as the final Korean version of the PUF, without modifications. RESULTS: The multi-step process of forward translation, reconciliation, back-translation, cognitive debriefing, and proofreading of the Korean version of the PUF was completed. CONCLUSIONS: The Korean version of the PUF scale may be helpful for screening IC patients in the Korean population and can now be used in Korea.

PURPOSE: To document the usefulness of early image acquisition using the contrast-enhanced dynacic MR imagingfor characterization of various focal hepatic lesions during the arterial phase. MATERIALS AND METHODS:Seventy-nine patients with 145 focal liver lesions (71 hemangiomas, 59 hepatocellular carcinomas and 15metastases) underwent breathhold dynamic MR imaging using a fast low-angle shot sequence. After obtainingunenhanced T1-weighted images, four phase MR images were obtained 10, 35, 60 and 300 seconds after starting theinjection. Patterns of contrast enhancement were analyzed for each lesion, with an emphasis on first phase images. RESULTS: Forty-two of the 59 HCCs (71%) showed prominent contrast enhancement during the first phase. HCCssmaller than 2cm in diameter showed a more homogeneous enhancement pattern than those which measured 2cm ormore(24/25 vs 12/17;P<.05). Hemangiomas showed a globular enhancement pattern during the same phase in 51 of 71cases (72%), a finding which was more apparent in those whose diameter was 2cm or more(35/54 vs 16/17, p<.05).During the first phase of imaging, 12 of the 15 metastases showed peripheral enhancement of their thick rim. CONCLUSION: The use of early image acquisition on dynamic MR sequences is helpful in character-izing lesionsaccrding to their pattern of contrast enhancement.
