PURPOSE: Climacturia is involuntary loss of urine during orgasm. The mechanism of climacturia in men who undergo radical prostatectomy (RP) is not fully understood, while deficiency in bladder neck coaptation during orgasm may be the cause. We evaluated the prevalence and risk factors of climacturia after RP. MATERIALS AND METHODS: We retrospectively reviewed the medical records of prostate cancer patients who underwent RP from 2002 to 2013 and was able to have a vaginal intercourse postoperatively. RP was conducted using open or robot-assisted approach. We analysed the symptoms of climacturia, relationship between climacturia and several clinical factors. Also, we tried to find factors to predict the presence of climacturia. RESULTS: Total of 123 patients were analyzed in this study. The median age of the men was 65 year and postoperative follow-up period for the interview was 37 months. Of the total 123 patients, 29 (23.6%) complained of the climacturia. In climacturia group, robot-assisted RP (p=0.018), nerve-sparing (p=0.046) and penile rehabilitation (p=0.012) were significantly less frequent, and more pad were comsumed (p=0.001) compared to non-climacturia group. On multivariable analysis, post-prostatectomy incontinence (PPI) (OR 6.49, p=0.004) and penile rehabilitation (OR 0.22, p=0.036) were significant factors to predict the presence of climacturia. CONCLUSIONS: Climacturia occurs in more than 20% patients who were potent enough after RP in our study. PPI and penile rehabilitation were positive and negative factor to predict an occurrence of climacturia, respectively. Therefore, in addition to PPI and erectile dysfunction, patients must be informed of this complication before undergoing RP.

PURPOSE: The factors that predict prostate cancer detection on repeat biopsy were evaluated in patients with atypical small acinar proliferation (ASAP) on the initial biopsy. MATERIALS AND METHODS: From 2003 to 2008, 3,130 men with suspected prostate cancer underwent a prostate needle biopsy, and 244 (7.8%) were diagnosed as having ASAP. One hundred seventy of 244 patients were rebiopsied at least once more. They were classified into a prostate cancer group and a noncancer group according to the final pathological diagnosis. The database of rebiopsied patients included age, initial prostate-specific antigen (PSA), PSA density (PSAD), PSA velocity (PSAV), total prostate volume (TPV), and transitional zone volume of the prostate (TZV). We compared differences in the aforementioned parameters between the 2 groups. RESULTS: A total of 57 patients (33.5%) with ASAP were ultimately shown to have prostate cancer. Univariate analysis showed that PSAD (p=0.002), PSAV (p=0.001), TPV (p=0.035), and TZV (p=0.005) differed significantly between the cancer and noncancer groups. The results of the multivariate analysis showed that PSAD (p=0.022), PSAV (p<0.001), and TPV (p=0.037) had a statistically significant correlation with cancer detection. CONCLUSIONS: PSAD, PSAV, and TPV are predictive factors of prostate cancer in patients with an initial diagnosis of ASAP of the prostate. Although repeat biopsy is mandatory irrespective of PSA values, the follow-up of PSA may help to estimate the probability of cancer in these men.

PURPOSE: We studied the results of urine cultures and antimicrobial sensitivity tests according to the voiding method used by spinal cord injury (SCI) patients over a recent 10-year period. MATERIALS AND METHODS: We retrospectively analyzed 1,236 urine samples and their antimicrobial sensitivity tests for 112 patients who had used only one voiding method between January 2000 and December 2009. The voiding methods were classified into four groups: clean intermittent catheterization (CIC), suprapubic catheterization, urethral Foley catheter, and spontaneous voiding. RESULTS: Of the 1,236 urine samples, 925 (74.8%) were positive and 279 (30.2%) had more than one bacteria. The CIC group showed the lowest rate of bacteriuria, colony counts, and polymicrobial infection (p<0.001). Causative organisms were mostly Gram-negative bacteria (84%), including Pseudomonas aeruginosa (22.9%), Escherichia coli (21.1%), Klebsiella species (6.7%), and Citrobacter species (6.3%). The rate of Gram-positive bacterial infection was 13.6%, and major pathogenic organisms were Streptococcus species (8.6%) and Staphylococcus species (2.6%). Major pathogenic organisms and the results of antimicrobial sensitivity tests differed according to the voiding method. CONCLUSIONS: Although the patient's condition and preferences are important when choosing the method of bladder management, CIC is the best voiding method for reducing urinary tract infections in SCI patients. When immediate use of antibiotics is needed for treatment of urinary tract infections, an appropriate antibiotic can be chosen according to the voiding method on the basis of our study and can be administered before the results of an antimicrobial sensitivity test are available.

This is a case report of 3 patients who had a dramatic and long-term complete response after antiandrogen withdrawal. All 3 patients were diagnosed with advanced or metastatic prostate cancer with a high prostate-specific antigen (PSA) level. For all patients, we started combined androgen blockade as androgen deprivation therapy and the PSA concentration decreased to <0.1 ng/mL, but then started to increase. After discontinuation of antiandrogen the PSA concentration decreased again and has remained below the limit of sensitivity for more than 1 year in all 3 patients.

BACKGROUND: Infective endocarditis shows high surgical mortality and morbidity rates, especially for aortic endocarditis. This study attempts to investigate the clinical characteristics and operative results of isolated aortic endocarditis. MATERIAL AND METHOD: From July 1990 to May 2005, 25 patients with isolated aortic endocarditis (Group I, male : female=18 : 7, mean age 43.2+/-18.6 years) and 23 patients with isolated mitral endocarditis (Group II, male : female=10 : 13, mean age 43.2+/-17.1 years) underwent surgical treatment in our hospital. All the patients had native endocarditis and 7 patients showed a bicuspid aortic valve in Group I. Two patients had prosthetic valve endocarditis and one patientsdeveloped mitral endocarditis after a mitral valvuloplasty in Group II. Positive blood cultures were obtained from 11 (44.0%) patients in Group I, and 10 (43.3%) patients in Group II. The preoperative left ventricular ejection fraction for each group was 60.8+/-8.7% and 62.1+/-8.1% (p=0.945), respectively. There was moderate to severe aortic regurgitation in 18 patients and vegetations were detected in 17 patients in Group I. There was moderate to severe mitral regurgitation in 19 patients and vegetations were found in 18 patients in Group II. One patient had a ventricular septal defect and another patient underwent a Maze operation with microwaves due to atrial fibrillation. We performed echocardiography before discharge and each year during follow-up. The mean follow-up period was 37.2+/-23.5 (range 9~123) months. RESULT: Postoperative complications included three cases of low cardiac output in Group I and one case each of re-surgery because of bleeding and low cardiac output in Group II. One patient died from an intra-cranial hemorrhage on the first day after surgery in Group I, but there were no early deaths in Group II. The 1, 3-, and 5-year valve related event free rates were 92.0%, 88.0%, and 88.0% for Group I patients, and 91.3%, 76.0%, and 76.0% for Group II patients, respectively. The 1, 3-, and 5-year survival rates were 96.0%, 96.0%, and 96.0% for Group I patients, and 100%, 84.9%, and 84.9% for Group II patients, respectively. CONCLUSION: Acceptable surgical results and mid-term clinical results for aortic endocarditis were seen.

BACKGROUND: To maximize the histological advantage and minimize the physiological disadvantage, we have been using the skeletonized gastroepiploic artey (GEA) as a free graft for total arterial revascularization. The aims of the current study was to assess the efficacy of the skeletonized GEA as a composite or extended graft for total arterial revascularization. MATERIAL AND METHOD: Between January 2000 and Feburary 2005, 133 patients (43 female, mean age=61.8 yrs) undergoing coronary artery bypass grafting (CABG) with a skeletonized GEA as free graft (22 extended, 107 composite and 4 others) were enrolled in this study. Coronary angiograms were performed in the immediate (median 14 days, n=86), early (median 366 days, n=56) and midterm (median 984 days, n=29) postoperative periods. RESULT: There were 3 (2.2%) early and 4 (3.3%) late cardiac-related deaths. The mean number of distal anastomoses per patient was 3.34 for total graft and 1.92 for GEA graft. The immediate, early, and midterm GEA patency were 157/159 (98.7%), 106/112 (94.6%), and 53/56 (94.6%), respectively. During follow-up, four patients required percutaneous intracoronary intervention because of GEA and target coronary artery stenosis or competitive flow. CONCLUSION: These data demonstrate satisfactory clinical and angiographic results in the skeletonized GEA as free graft for total arterial revascularization. Although we need a careful longer follow-up, the skeletonized GEA as a free graft will be a valuable option 'to be' for CABG.

Prostate cancer is the most common type of male cancer worldwide. Although radical prostatectomy (RP) is advised for prostate cancer in patients with a life expectancy of more than 10 years by various guidelines, most elderly men still do not undergo the procedure regardless of increasing life expectancy. This study aimed to determine whether RP is suitable for patients with prostate cancer aged 75 years or older. A retrospective study of patients who underwent RP at 6 institutions between 2005 and 2012 was conducted. Patients were divided into 2 groups at the time of surgery: 65-69 years (younger group) and 75 years or older (older group). We compared clinical characteristics, pathological results, complication rates, and recurrence-free survival between the two groups. Compared with the younger group, the older group had significantly higher preoperative serum prostate-specific antigen level, pre- and postoperative Eastern Cooperative Oncology Group (ECOG) performance status grade, hypertension prevalence, and Gleason score at biopsy and RP. However, except urinary incontinence, there were no statistically significant differences in the peri- and post-operative complications. After median follow-up periods of 36 months (younger group) and 40 months (older group), the biochemical recurrence-free survival rates were not significantly different (P = 0.581). Although the urinary incontinence rate was higher in the older group, RP was a suitable option for selected Korean men aged 75 years or older with limited complication rates and excellent outcomes similar to those for patients aged 65-69 years.

PURPOSE: Single incision laparoscopic cholecystectomy (SILC) is generally performed with the use of inverse triangulation. In this study, we performed 3-channel or 4-channel SILC without the use of inverse triangulation. We evaluated the adequacy and feasibility of SILC using our surgical method. METHODS: We retrospectively reviewed our series of 309 SILCs performed between March 2014 and February 2015. RESULTS: Among 309 SILCs, male were 148 and female were 161 patients, mean age was 48.7 +/- 15.3 years old and mean body mass index was 24.8 +/- 3.8 kg/m2. Forty patients had previously undergone abdominal surgery including 6 cases of upper abdominal surgery. SILC after percutaneous transhepatic gallbladder (GB) drainage was completed in 8.7% of cases. There were 10 cases of emergency SILC. SILC was performed for noncomplicated GB including symptomatic GB stone and polyp in 66.7% of cases, acute cholecystitis in 33.3%. Overall, 96.8% of procedures were successfully completed without additional port. The reason for addition of an extra port or open conversion included technical difficulties due to severe adhesion and bleeding. The mean operating time was 60.7 +/- 22.3 minutes. The overall complication rate was 4.8%: 9 patients of wound seroma, 1 case of bile leakage from GB bed, 4 cases of intra-abdominal abscess or fluid collection, and 1 case of incisional hernia were developed. There was no case of common bile duct injury. CONCLUSION: Our surgical method of SILC without the use of inverse triangulation is safe, feasible and effective technique.

PURPOSE: To investigate the treatment outcome and the toxicity of helical tomotherapy (HT) in patients with metastatic colorectal cancer (mCRC). MATERIALS AND METHODS: We retrospectively reviewed 18 patients with 31 lesions from mCRC treated with HT between 2009 and 2013. The liver (9 lesions) and lymph nodes (9 lesions) were the most frequent sites. The planning target volume (PTV) ranged from 12 to 1,110 mL (median, 114 mL). The total doses ranged from 30 to 70 Gy in 10-30 fractions. When the alpha/beta value for the tumor was assumed to be 10 Gy for the biologically equivalent dose (BED), the total doses ranged from 39 to 119 Gy10 (median, 55 Gy10). Nineteen lesions were treated with concurrent chemotherapy (CCRT). RESULTS: With a median follow-up time of 16 months, the median overall survival for 18 patients was 33 months. Eight lesions (26%) achieved complete response. The 1- and 3-year local progression free survival (LPFS) rates for 31 lesions were 45% and 34%, respectively. On univariate analysis, significant parameters influencing LPFS rates were chemotherapy response before HT, aim of HT, CCRT, PTV, BED, and adjuvant chemotherapy. On multivariate analysis, PTV < or =113 mL and BED >48 Gy10 were associated with a statistically significant improvement in LFPS. During HT, four patients experienced grade 3 hematologic toxicities, each of whom had also received CCRT. CONCLUSION: The current study demonstrates the efficacy and tolerability of HT for mCRC. To define optimal RT dose according to tumor size of mCRC, further study should be needed.

PURPOSE: The objective was to study whether positive surgical margins (PSMs) predict biochemical recurrence (BCR) in all patients without adjuvant therapy after radical prostatectomy (RP). MATERIALS AND METHODS: We retrospectively reviewed the medical records of patients who underwent RP for prostate cancer at Veterans Health Service Medical Center from 2005 to 2011. BCR was defined by a prostate-specific antigen (PSA) value > or =0.2 ng/mL. The clinicopathological factors of the PSM group were compared with those of the negative surgical margin (NSM) group, and the predictive impact of a PSM for BCR-free survival were evaluated. In addition, we analyzed the prognostic difference for BCR-free survival between solitary and multiple PSMs. RESULTS: A PSM was noted in 167 patients (45.5%). BCR was reported in 101 men in total (27.5%). The BCR-free survival rate of the PSM group was lower than that of the NSM group (p<0.001). In a multivariate analysis for the total patients, PSM was significantly associated with BCR-free survival (p<0.001). After stratification by pathological T stage, Gleason score (GS), and preoperative PSA value, PSM was significantly predictive for BCR-free survival in men with pT2 and/or GS < or =6 or 7 and/or a PSA value <10 or 10-20 ng/mL (all p<0.05). Multiple PSMs were more predictive of BCR-free survival than was a solitary PSM (p=0.001). CONCLUSIONS: A PSM is a significant predictor of postoperative BCR in patients with pT2 and/or GS < or =7 and/or preoperative PSA <20 ng/mL. Multiple PSMs are considered a stronger prognostic factor for prediction of BCR than is a solitary PSM.
