OBJECTIVE: To evaluate the degree of streptococcal colonization in Korean pregnant women. METHODS: The study comprised of 153 singleton pregnant women who visited Severance Hospital for delivery, and their neonates. Specimens for GBS culture were collected by a sterile cotton swab from lower vagina and cervix of pregnant women, and from ear canal and throat of neonates. They were first cultured for 48 hours in Todd-Hewitt broth and then subcultured onto Tryptose blood agar plates(Difco). Group B streptococci were confirmed by the presence of beta-hemolysis and a positive reaction with Phadebact group B Streptococci reagent(Karo Biodiagnostics AB, Huddinge, Sweden). RESULTS: The prevalence of positive cultures in pregnant women and neonates were 2.61%(4/153) and 0%(0/4), respectively. In the study population there was a case of suspicious group B streptococcual sepsis in an infant whose mother was colonized. CONCLUSIONS: In our study the GBS colonization rate in Korean pregnant women was significantly lower than that of other countries. The reason for this difference may be associated with a racial differences, or social factors such as socio-economic status or a life style.

Purpose: A laparoscopic radical nephrectomy is known to cause less morbidity than a traditional open radical nephrectomy. In our institution, the laparoscopic approach, with intact specimen removal, has become the standard technique for radical nephrectomies. Herein, we report the results and oncological outcome of the experience of a single center. Materials and Methods: We reviewed 68 transperitoneal laparoscopic radical nephrectomies, performed for suspected renal cell carcinoma between December 1999 and June 2006. All data were collected from the patient's medical records. Results: The mean tumor size, surgical time and estimated blood loss were 4.82cm (1.7-14), 228.5 min (120-480) and 409.1cc (32-1,312), respectively. Conversion to open surgery was required in one case due to Endo-GIA malfunction, and conversion to hand-assisted surgery was performed in one case. The histological findings were pT1, pT2 and pT3 in 40 (59.7%), 9 (13.4%) and 18 patients (26.9%), respectively. In one case, the histology confirmed a non-malignant disease. The follow-up period was from 3 to 80 months (median 18). Distant metastasis was observed in 2 cases, but there was no local recurrence or port metastasis. Conclusions: A laparoscopic radical nephrectomy is a safe and feasible treatment for localized renal cell carcinomas. Longer follow-up and large scale studies are necessary to evaluate the long-term survival and disease- free rates, and confirm the effectiveness of performing a radical laparoscopic nephrectomy.

3.Early Results after the Treatment with Total Hip Arthroplasty with Larger Diameter Femoral Head versus Bipolar Arthroplasty in Patients with Femoral Neck Fractures.
Journal of the Korean Hip Society 2007;19(4):463-467
PURPOSE: To study the short-term clinical outcomes of THA with a large diameter femoral head (36 mm) and BA in physiologically active elderly patients with displaced femoral neck fractures MATERIALS AND METHODS: This non-concurrent clinical trial included 40 patients with displaced femoral neck fractures, who had been treated with prosthetic replacement from February 2004 and December 2004. Twenty patients underwent either THA or BA. The mean follow-up period was 18 months(12~26). The clinical outcome was analyzed, and the latest follow-up radiographs were assessed to determine the number of complications, such as osteolysis, loosening, fracture, dislocation, etc. RESULTS: The clinical and functional results were better in the THA group than in the BA group. The mean operation time was significantly shorter in the BA group than in the THA group. The mean intra-operative blood loss was similar in the two groups. Despite there being no limitation of the range of motion in the early post-operative period, there was no dislocation encountered in either group. CONCLUSION: A THA with a large diameter femoral head is recommended for the management of patients with femoral neck fractures because THA produces a better result than BA.

PURPOSE: We aimed to identify microbiological characteristics in patients with acute prostatitis after transrectal prostate biopsy to provide guidance in the review of prevention and treatment protocols. MATERIALS AND METHODS: A retrospective analysis of medical records was performed in 1,814 cases who underwent prostate biopsy at Seoul St. Mary's Hospital and St. Vincent's Hospital over a 5 year period from 2006 to 2011. Cases in which acute prostatitis occurred within 7 days after the biopsy were investigated. Before starting treatment with antibiotics, sample collections were done for culture of urine and blood. Culture and drug susceptibility was identified by use of a method established by the Clinical and Laboratory Standards Institute. RESULTS: A total of 1,814 biopsy procedures were performed in 1,541 patients. For 1,246 patients, the procedure was the first biopsy, whereas for 295 patients it was a repeat biopsy. Twenty-one patients (1.36%) were identified as having acute bacterial prostatitis after the biopsy. Fifteen patients (1.2%) had acute prostatitis after the first biopsy, and 6 patients (2.03%) experienced acute prostatitis after a repeat biopsy. Even though the incidence of acute bacterial prostatitis was higher after repeat biopsy than that after the first biopsy, there was no statistically significant intergroup difference in terms of incidence (chi2=1.223, p=0.269). When the collected urine and blood samples were cultured, Escherichia coli was found in samples from 15 patients (71.4%), Klebsiella pneumoniae in 3 patients (14.3%), Enterobacter intermedius in 1 patient (4.8%), E. aerogenes in 1 patient (4.8%), and Pseudomonas aeruginosa in 1 patient (4.8%). A fluoroquinolone-resistant strain was confirmed in 5 cases (23.8%) in total. Three cases of E. coli and 1 case of Klebsiella had extended-spectrum beta-lactamase activity. CONCLUSIONS: Empirical treatment of acute prostatitis should be done with consideration of geographical prevalence and drug resistance. This study will provide meaningful information for the management of acute prostatitis after transrectal prostate biopsy.

PURPOSE: A prospective multi-center study was conducted to evaluate the safety and efficacy of alfuzosin (10 mg), for male lower urinary tract symptoms (LUTS) associated with benign prostatic hyperplasia (BPH) in primary care clinics. MATERIALS AND METHODS: Three hundred twenty-four patients with complaints of LUTS associated with BPH were enrolled from 17 clinics. Patients received a 12-week course of 10 mg alfuzosin (Bearxat(R)XL Tablet) once daily, and underwent follow-up at 2~4 and 12 weeks post-treatment. The maximum flow rate (Qmax) and residual urine volume (RUV) were measured at each visit. The International Prostate Symptom Score (IPSS), Quality of Life (QoL), and International Index of Erectile Function (IIEF-5) were evaluated at baseline and post-treatment. During the study period, the presence of orthostatic hypotension was evaluated by blood pressure measurement before and after a postural change. Any adverse effects of alfuzosin including retrograde ejaculation were assessed. RESULTS: Of the 324 enrolled patients, 62 (19.1%) patients dropped out and a total of 262 patients were evaluated. Each value of Qmax, RUV, IPSS, QoL, and IIEF-5 was significantly improved from 14.19+/-8.85 ml/sec, 41.10+/-81.44 ml, 18.04+/-7.36, 3.81+/-0.86, and 11.75+/-6.91, respectively, at baseline, to 15.68+/-6.25 ml/sec, 24.29+/-29.46 ml, 12.19+/-5.59, 2.54+/-0.91, and 12.33+/-7.55, respectively, at end-point. Retrograde ejaculation was found in 2 patients (2/255, 0.78%) at 2~4 weeks and 1 patient (1/152, 0.66%) at 12 weeks. The frequency of orthostatic hypotension was 13.27% (30/226) at baseline, 13.11% (27/206, p=0.8658) at 2~4 weeks, and 14.29% (19/133, p=0.8348) at end-point. The number of patients with adverse events was 36 where the number of adverse events was 60. Among those 60 adverse events, 8 events were related to treatment, which consisted of headache (2), dizziness (2), palpitation (1), voiding difficulty (1), erectile dysfunction (1), and arthralgia (1). CONCLUSIONS: Treatment with alfuzosin (10 mg) once daily led to significant improvements in LUTS associated with BPH and QoL in primary care clinic patients. alfuzosin (10 mg) use resulted in few hypotensive events, no deleterious effect on sexual function, and no drug related SAEs during the study. The study findings suggest that alfuzosin (10 mg) can be safely prescribed in primary care clinics for male LUTS with efficacy.

Every year 150 million new cases of sexually transmitted infection are expected to occur around the world with high occurrence and morbidity rates in both males and females. To respond to dramatically changing social and cultural environments, clinical treatment guidelines for diagnosis, treatment, and prevention of sexually transmitted infections have been developed in many countries, and South Korea has also prepared treatment guidelines which can be used in medical institutions treating primarily these diseases. Against this background, this study conducted a 31-item questionnaire survey by mail and e-mail to investigate the actual clinical practices of physicians treating sexually transmitted infections. In total, 250 and 1,068 questionnaires were distributed through mail and e-mail, respectively, and 274 of them were completed and returned for a response rate of 20.8%. According to the results, physicians' actual clinical practices were found to be different from textbook guidelines to some degree. Therefore, treatment guidelines that take into account the current situation for sexually transmitted infections should be developed in Korea, and a foundation for national management of the diseases should be established through active advertisements.

Purpose:
To develop a rat model of bladder calculi in the neurogenic bladder following spinal cord injury (SCI) and assess bacterial communities within the biofilm of bladder calculi using denaturing gradient gel electrophoresis (DGGE).
Methods:
The silk tied to a small segment of the Teflon IV catheter was implanted through the urethra into the bladder of rats with SCI induced by T9 laminectomy. After 6 months, the rats were sacrificed and their bladder calculi were collected by opening the bladders through the low-midline incision. Genomic DNA was extracted from the biofilm of bladder calculi followed by DGGE to obtain bacterial DNA. The DNA sequences were compared and analyzed using BLAST (Basic Local Alignment Search Tool) to identify bacteria.
Results:
After placing silk nidus in the bladder for 6 months, all 6 rats developed bladder calculi. According to DGGE analysis, Pseudomonas aeruginosa was the most dominant strain, while Clostridium sp. and Lactobacillus sp. were relatively dominant strains within the biofilm of bladder calculi in the rats with SCI.
Conclusions
DGGE analysis showed various microorganisms in the biofilm of calculi arising from a neurogenic bladder rat model. This research design can be the basis for clinical studies and may be applied to calculi in patients with neurogenic bladder following SCI.

Purpose:
To investigate the effect of dapagliflozin, a sodium-glucose cotransporter 2 inhibitor, on inflammatory cytokines of urogenital tissue in a rat model of type 2 diabetes (T2DM) to infer pharmaceutical influence of dapagliflozin on genitourinary infection or inflammation.
Methods:
Study animals were divided into the following 4 groups of 10 animals each: (1) the Otsuka Long-Evans Tokushima Fatty (OLETF)-DA group treated with dapagliflozin at 1.0 mg/kg/day, (2) the OLETF-VO group treated with voglibose at 0.6 mg/kg/day, (3) the control group (OLETF-CO) given water, and (4) the Long-Evans Tokushima Otsuka (LETO) rats were included as nondiabetic control group. Changes in blood glucose, 24-hour urine volume, and urine glucose were measured. The interleukin-1β (IL-1β) and interleukin-18 (IL-18) levels in the bladder and the urethra were quantified, respectively.
Results:
The urine glucose level and the 24-hour urine volume at 12 weeks of treatment were significantly higher in the OLETF-DA group than that in any other group (P<0.05). The cytokine analysis of the bladder and urethra showed higher IL18 and IL-1β in the OLETF-DA and the OLETF-CO groups than that in the OLETF-VO and LETO groups (P<0.05). The cytokine levels did not differ between the OLETF-DA and the OLETF-CO groups, and the level of IL-18 in the OLETF-DA group was higher in the urethra than in the bladder.
Conclusions
This study revealed that dapagliflozin increased the urine glucose concentration, resulting in an inflammatory response remain in the urogenital tract as the untreated diabetic rats. Therefore, when treating patients with T2DM with dapagliflozin, careful attention should be paid to genitourinary infection or inflammation.

PURPOSE: We performed this study to estimate the correlation of serum testosterone and lower urinary tract symptom (LUTS) in adult hypogonadism patients. MATERIALS AND METHODS: Medical records of ninety men over forty years old who have LUTS, International Prostate Symptom Score (IPSS) above 7 were reviewed. The correlations of serum testosterone level withage, International Prostate Symptom Score (IPSS), prostate volume, prostate specific antigen (PSA) and maximal flow rate were assessed using Spearman test. The statistical differences of IPSS, prostate volume, PSA and maximal flow rate in 3 groups of patients divided by serum testosterone levels(<2.0, 2.0-3.5, >3.5 ng/ml). RESULTS: Serum testosterone level decreased according to increase of age (r=-0.28, p=0.07). Serum testosterone has no significant correlation with IPSS, prostate volume, PSA and maximal flow rate. There was no significant difference of IPSS, prostate volume, PSA and maximal flow rate according to the levels of testosterone. CONCLUSIONS: Emerging from this analysis, clinical indexes of LUTS may not be connected with testosteronelevel and LUTS may not be affected by hypogonadism. Further more objective and sophisticated studies with large number of subjects are requested for the understanding of pathophysiology of LUTS in hypogonadism.
