OBJECTIVE: To evaluate the effect of tumor necrosis factor-alpha (TNF-alpha)gene transduced bladder tumor cells on survival of C3H/He mice. MATERIALS AND METHODS: The complete cDNA of TNF-alpha was introduced to mouse bladder tumor cell line(MBT-2) using a retroviral vector. Gene transfer and expression were confirmed by polymerase chain reaction(PCR) and reverse transcription polymerase chain reaction(RT-PCR). Produced TNF-alpha was measured by ELISA. TNF-alpha gene transduced and parental cells were xenografted in C3H/He mice. Implantation and growth rate and survival of experimental animals were analysed. RESULTS: Successful gene transfer and expression were confirmed. TNF-G gene transduced MBT-2 cells secreted TNF-alpha at the concentration of 47.4pg/106cells/24hours. The implantation and growth rate of TNF-t gene transduced MBT-2 cells were much lower than those of parental cells and survival of experimental animals was different between TNF-t gene transduced MBT-2 and parental cells(P<0.05). CONCLUSION: This study shows potential advantages of localized TNF-a secretion to induce potent antitumorigenic response. Tumor cell targeted TNF-a gene therapy could become a useful tool in treatment of bladder cancer.

PURPOSE: To evaluate clinical characteristics of ileal neobladder as orthotopic bladder substitution, we examined the urodynamic characteristics, clinical symptoms and radiologic findings of 11 patients who had undergone ileal nobladder substitution following cystectomy or cystoprostatectomy. MATERIALS AND METHOD: From February 1993 to July 1996, 11 patients underwent lower urinary tract reconstruction with ileal neobladder. Cystectomy or cystoprostatectomy was done, and reservoirs were connected to the proximal urethra or urethrovesical junction. Urodynamic and radiologic studies were performed to evaluate neobladder function and upper tract. Clinical symptoms were evaluated via a detailed patient questionaire. RESULTS: Mean cystometric capacity was 434m1(293-640m1). All patients voided by Valsalva maneuver and achieved good peak flow rates(mean value was 22.6m1/sec). Of the patients 10 emptied bladder to near completion with a mean post-void residual of 30m1, while 1 had post-void residuals of 110m1 The neobladder demonstrated good compliance for the storage of urine Phasic neobladder contractions were present during filling cystometrography. While the number of phasic contractions increased at higher neobladder volumes, the mean length and mean pressure of phasic contractions were not Increased a higher neobladder volumes. Daytime continence was obtained in all patients(100%), while nighttime continence was achieved in 8 patients (73%). Of these 8 nighttime continent patients, 4 patients(50%) had to void at least once a night to keep dry. No difference was found in any urodynamic parameter between nighttime continent and incontinent patients. There was no difference in any important urodynamic parameter between patients who had and had not received post-operative chemotherapy. Renal function, based on serum creatinine levels, had remained stable and no significant electrolyte or acid-base imbalance was found in all patients. Voiding cystourethrograms obtained in 9 patients revealed 3 patients(33%) had grades ll-lll/V reflux IVP in 9 patients revealed hydronephrosis in 1/18(5.5%) of renal units. CONCLUSIONS: Neobladder constructed from detubularized ileum achieves adequate capacity at low pressures with a satisfactory continence rate. We conclude that neobladder may be the best choice of urinary diversion after cystectomy in the aspect of quality of life.

Purpose: To assess awareness of prostate cancer and prostate cancer screening in high risk Korean men 40 years and older.
Materials and Methods: The Korean Urological Oncology Society implemented an online survey of 600 men aged 40 years or older from July 30 to August 6, 2019 to ask questions about prostate cancer and screening.
Results: Of the 600 respondents, 96.5% (579 of 600) were aware of prostate cancer and 49.8% (299 of 600) thought they were at risk. Men in their 60s, men with a family history and men with urological conditions were more concerned about prostate cancer. Most respondents (83.3%, 500 of 600) had never received prostate cancer screening. When asked why they had not, (multiple choices: first, second and third priority), the most common responses were: “They had no symptoms of prostate cancer”; “They were in good health”; “Cost burden of screening”; and “They thought screening was included in the National Health Examination Program.” Only 9.7% (58 of 600) were aware of prostate-specific antigen (PSA). After being informed about PSA, 97.7% (586 of 600) wanted it to be included in national cancer screening.
Conclusions In this survey, 96.5% of respondents were aware of prostate cancer, and 44.2% recognized the need for early screening. However, only 16.7% had received screening. Awareness of prostate cancer risks tended to be high in elderly people, people with a family history and people with urological conditions. The results also indicate that there is support for national-level management and early screening programs for prostate cancer. (Korean J Urol Oncol 2020;18:40-46)

“Clinical Practice Guideline for Stroke Rehabilitation in Korea 2016” is the 3rd edition of clinical practice guideline (CPG) for stroke rehabilitation in Korea, which updates the 2nd edition published in 2014. Forty-two specialists in stroke rehabilitation from 21 universities and 4 rehabilitation hospitals and 4 consultants participated in this update. The purpose of this CPG is to provide optimum practical guidelines for stroke rehabilitation teams to make a decision when they manage stroke patients and ultimately, to help stroke patients obtain maximal functional recovery and return to the society. The recent two CPGs from Canada (2015) and USA (2016) and articles that were published following the 2nd edition were used to develop this 3rd edition of CPG for stroke rehabilitation in Korea. The chosen articles' level of evidence and grade of recommendation were decided by the criteria of Scotland (2010) and the formal consensus was derived by the nominal group technique. The levels of evidence range from 1++ to 4 and the grades of recommendation range from A to D. Good Practice Point was recommended as best practice based on the clinical experience of the guideline developmental group. The draft of the developed CPG was reviewed by the experts group in the public hearings and then revised. “Clinical Practice Guideline for Stroke Rehabilitation in Korea 2016” consists of ‘Chapter 1; Introduction of Stroke Rehabilitation’, ‘Chapter 2; Rehabilitation for Stroke Syndrome, ‘Chapter 3; Rehabilitation for Returning to the Society’, and ‘Chapter 4; Advanced Technique for Stroke Rehabilitation’. “Clinical Practice Guideline for Stroke Rehabilitation in Korea 2016” will provide direction and standardization for acute, subacute and chronic stroke rehabilitation in Korea.
