Hemorrhagic fever with renal syndrome (HIFRS), scrub typhus, murine typhus and leptospirosis have been the principal acute febrile diseases in Korea. To evaluate the seroepidemiologic patterns of acute febrile illness, sera collected from 2,423 patients in 1996 were examined for antibodies against Hantaan virus, Orientia tsutsugamushi, Rickettsia typhi, and Borrelia burgdorferi by indirect immunofluorescent antibody technique (IFA) and macroscopic agglutination test for Leptospira interogans. Seropositive cases against O. tsutsugamushi, Rickettsia typhi, Leptispira interogans and Hantaan virus were 192 (7.9%), 193 (8.0%), 12 (0.5%) and 324 (13.4%), respectively. Male was more affected in HFRS and murine typhus contrasting to scrub typhus and leptospirosis in female. Most positive cases occurred during October and November for scrub typhus, and during November and December for HFRS. These results showed similar patterns with previous epidemical data for recent couple of years, and possibly implied no significant changes occurred in ecologic situations for acute febrile diseases in Korea.

There is controversy regarding the survival benefits of eliminating primary tumors via cytoreductive radical prostatectomy (CRP) in patients with metastatic prostate cancer (mPCa). The purpose of this article is to review the theoretical background of and rationale for CRP, and the current knowledge base. The Scopus and PubMed databases were searched for studies investigating CRP published between January 2000 and October 2019. The retrieved articles were nonsystematically reviewed. Based on preclinical data, retrospective patient case studies, retrospective population-based studies, and prospective studies, CRP has been reported to afford benefits for the treatment and prevention of local symptoms through the removal of primary tumors, and the management of neo-metastatic disease and overall survival. However, despite the results from these studies, the current review mostly addresses small case studies and uncontrolled population-based studies with weak evidence. Based on this weak evidence, therefore, clinical use has not yet been recommended. Further research investigating the role and timing of CRP in patients with mPCa is needed, in addition to studies screening the most suitable populations for CRP.

Purpose: An acute ureteral obstruction during pregnancy presents both diagnostic and therapeutic challenges. When conservative therapy fails, temporary measures, such as ureteral stenting, are often chosen as a first- line intervention, which postpones definitive management until delivery. The usefulness of ureteral stenting was evaluated as an emerging strategy for the symptoms of an acute ureteral obstruction during pregnancy. Materials and Methods: Between 1996 and 2005, a retrospective analysis was performed on 53 pregnant patients with an acute ureteral obstruction. Eighteen of the patients were treated by ureteral stenting, as they failed to improve with conservative management. They were followed up until the removal of the ureteral stent. Results: Seventeen patients (95%) experienced significant pain relief within at least 2 days, but one patient (5%) did not. On ultrasound, 16 patients (88%) had resolution of hydronephrosis. Twelve patients (66%) continued to have problems with post-therapeutically irritative voiding symptoms, but 11 (61%) experienced relief of symptoms within 10 days. One patient (5%) had the ureteral stent removed due to the continuous complaint of irritative voiding symptoms. After delivery, all patients were taken intravenous pyelography (IVP). Fourteen patients showed normal findings, but 4 were diagnosed with a ureteral stone. Three patients were treated by extracorporeal shock wave lithotripsy (ESWL) for a stone in the upper and lower urinary tract. One patient, with a mid ureteral stone, was treated by ureteroscopic lithotripsy. Conclusions: Ureteral stents were usually placed without any major problems, and well tolerated, with only minor and short post-therapeutic discomfort. We concluded that ureteral stenting is a simple, safe and effective first-line therapeutic option in case of symptomatic and acute ureteral obstruction during pregnancy.

PURPOSE: We compared prophylactic effects and complications of intravesical instillation of the Connaught and Tice strains bacillus Calmette-Guerin (BCG) in patients with stage pT1 bladder cancer. MATERIALS AND METHODS: A total of 98 patients with stage pT1 bladder cancer were treated with transurethral resection (TUR) between January 1992 and April 1998. Of the 98 patients, 51 received the Connaught strain BCG (81mg), 27 the Tice strain BCG (12.7mg) and 20 patients underwent TUR alone. The patients were followed-up for 18-78 months (mean 42.5months). The recurrence and progression rates, mean months to tumor recurrence, recurrence free survival rate, using Kaplan-Meier curve, and complications, were compared between the two BCG strain groups. RESULTS: The overall recurrence rate was 27.5% in the Connaught strain BCG group, 29.6% in Tice strain BCG group and 65% in TUR alone group. The mean months to tumor recurrence, and the recurrence free survival rate, showed that both BCG strain drugs were superior to TUR alone. Although the prophylactic efficacy of the Connaught strain BCG was a little higher than that of the Tice strain BCG, there were no significant differences in the recurrence rates and recurrence free survival rates between the two drugs. The incidences of complications were 94.1 and 85.2% in the Connaught strain BCG and Tice strain BCG groups, respectively. CONCLUSIONS: Both the Connaught and Tice BCG strains were superior to TUR alone in the prophylaxis of the recurrence in stage pT1 bladder cancer. There was no significant difference in the complication rates between the two groups. Therefore, both the Connaught and Tice BCG strains may be regarded as alternative treatments.

Historically, digital rectal examination (DRE) had been the only method available to evaluate the prostate gland for malignant tumor. Recently, serum prostate specific antigen (PSA), transrectal ultrasonography (TRUS) and magnetic resonance imaging (MRI) using endorectal coil have been added to the methods used to detect prostate cancer. But the roles of these tests in detecting cancer are currently undefined. Because of its low specificity, some reports have suggested the routine use of TRUS be discouraged. The present study was undertaken to evaluate the value of TRUS in the detection of prostate cancer. In a retrospective study, 123 BPH patients were examined by TRUS and PSA measurement. All patients were planned for prostatectomy and they had no evidence for prostate cancer at DRE. Of 123 patients with pathologically proven diagnosis, 10 patients had prostate cancer and 113 patients had BPH. Among the patients with prostate cancer, 6 patients had elevated PSA level ( >10ng/mL), while a patient had normal PSA level. Of 66 patients whose PSA levels were between 4 and 10ng/mL, only 3 patients had prostate cancer. Among 10 patients with prostate cancer, one patient had positive finding in TRUS, while 9 patients had negative finding. Among 113 patients with BPH, 17 patients had positive findings in TRUS and 96 patients had negative findings. Over all TRUS sensitivity and specificity for prostate cancer detection was 10% and 84.9% respectively. From our data we conclude; 1. The use of TRUS in BPH patients with negative DRE and PSA less than 10ng/mL seems to be questionable. 2. For the patients with negative DRE and PSA higher than 10ng/mL, sono-guided biopsy should be done regardless of the result of TRUS.

PURPOSE: Penile fracture is a rare but serious urological condition. Immediate surgical repair is widely accepted as the treatment of choice in penile fracture. The aim of this study is to investigate the long-term outcome of immediate surgical treatment of penile fracture. MATERIALS AND METHODS: This is a retrospective study of 12 men with penile fracture who were treated in the Department of Urology, Sanggyepaik Hospital, Seoul, Korea from January 2000 to June 2005. Diagnosis was made clinically and was confirmed by cavernosography in all our patients. All patients underwent immediate surgical repair, within two days after trauma, using a degloving incision. The long term results of the immediate surgical repair were evaluated using questionnaire on outpatient department visiting or telephoning. RESULTS: The median patient age was 43 years (range, 18 to 57 years). The median follow-up was 32 months (range, 14 to 60 months). Of these patients, 8 (66.7%) patients were injured during sexual intercourse, whereas 4 (33.3%) patients were injured during masturbation. All patients were treated by immediate surgery. All patients reported satisfactory, painless erectile function; two developed penile curvature and one had a penile nodule. CONCLUSIONS: Immediate surgical repair of penile fracture is effective, restores erectile function, and the incidence of complications is low.

PURPOSE: There has been considerable controversy regarding the treatment of urinary incontinence(UI). The aim of our study was to investigate the efficacy and safety of the suprapubic arch(SPARC) procedure for the management of UI in elderly women. MATERIALS AND METHODS: A retrospective analysis was conducted on 301 women who underwent the SPARC procedure for SUI. The patients were divided into two groups: group A(<65 years) and group B(> or=65 years). Among these patients, women with mixed urinary incontinence(MUI) were assigned to either group C(<65 years) or group D(> or=65 years). The objective and subjective SPARC success rates were evaluated postoperatively. RESULTS: There were 258 patients in group A, 43 patients in group B, 44 patients in group C, and 11 patients in group D. The objective surgical success rates for groups A and B were 97.7% and 95.3%, respectively (p=0.304). The subjective success rates for groups A and B were 97.3% and 95.3%, respectively(p=0.311). Recommendation rates for the SPARC procedure were 93% in group A and 93% in group B(p=0.5). In patients with MUI(groups C and D), the objective success rates were 93.2%(group C) and 81.8%(group D)(p=0.286). The subjective success rates were 93.2% (group C) and 81.8%(group D)(p=0.286). The complication rates were similar between the two study groups: 5.4%(group A) vs 7.0%(group B) (p=0.359). CONCLUSIONS: The SPARC procedure is effective and safe, and it offers a satisfactory success rate in elderly women with UI.

PURPOSE: The aim of this study was to evaluate possible predictive variables for the outcome of shock wave lithotripsy (SWL) of renal stones in a single center. MATERIALS AND METHODS: Between March 2008 and March 2010, a retrospective review was performed of 115 patients who underwent SWL for solitary renal stones. The patients' characteristics and stone size, location, skin-to-stone distance (SSD), and Hounsfield units (HU) of stone were reviewed. The impact of the possible predictors on the disintegration of the stones was evaluated by logistic regression analysis. Receiver operator characteristic (ROC) curves were generated to compare the predictive powers of the variables. RESULTS: Seventy-nine patients (68.7%) had successful outcomes, whereas 36 patients (31.3%) had residual stones. Significant differences were found in the mean size and mean HU of the stones (size: 8.34+/-3.58 mm vs. 13.57+/-5.41 mm, p<0.001; HU: 675.29+/-254.34 vs. 1,075.00+/-290.41, p<0.001). In the unadjusted model, age, stone size, and stone density were significant predictors. In the reduced model, stone density and size were significant predictors for the outcome of SWL. The area under the ROC curve (AUC) was significantly higher for stone density and size than for the other parameters, but the AUC between stone density and size did not differ significantly (stone density: 0.874, stone size: 0.827, p=0.388). CONCLUSIONS: Stone density and size were significant predictors of the outcome of SWL for renal stones less than 2.0 cm in diameter. We should consider HU and stone size when making decisions on the treatment of renal stones.
