RESUMEN
Purpose@#To compare improvement of lower urinary tract symptoms (LUTS) due to benign prostatic hyperplasia in diabetic versus nondiabetic patients after transurethral resection of the prostate (TURP) or holmium laser enucleation of the prostate (HoLEP). @*Methods@#The medical records of 437 patients who underwent TURP or HoLEP at a tertiary referral center from January 2006 to January 2022 were retrospectively analyzed. Among them, 71 patients had type 2 diabetes. Patients in the diabetic mellitus (DM) and non-DM groups were matched 1:1 according to age, baseline International Prostate Symptom Score (IPSS), and ultrasound measured prostate volume. Changes in LUTS were assessed at 3 months after surgery using IPSS and evaluated by categorizing patients according to prostatic urethral angulation (PUA; <50° vs. ≥50°). Medication-free survival after surgery was also investigated. @*Results@#No significant differences were noted between the DM and non-DM groups in baseline characteristics except for comorbidities (i.e., hypertension, cerebrovascular disease, and ischemic heart disease, P=0.021, P=0.002, and P=0.017, respectively) and postvoid residual urine volume (115±98 mL vs. 76±105 mL, P=0.028). Non-DM patients showed significant symptomatic improvement regardless of PUA, while DM patients demonstrated improvement in obstructive symptoms only in those with large PUA (≥51°). Among patients with small PUA, DM patients had worse medication-free survival after surgery compared to controls (P=0.044) and DM was an independent predictor of medication reuse (hazard ratio, 1.422; 95% confidence interval, 1.285–2.373; P=0.038). @*Conclusions@#DM patients experienced symptomatic improvement after surgery only in those with large PUA. Among patients with small PUA, DM patients were more likely to reuse medication after surgery.
RESUMEN
Chronic pelvic pain (CPP) refers to pain perceived in the pelvic region for over 6 months. It is described more specifically according to the organs involved. The diagnosis and classification of CPP are not easy because of the vague diagnostic criteria, variety of presenting symptoms, absence of diagnostic tools, and coexisting symptoms due to accompanying other diseases. This concise review aims to help urologists diagnose CPP by focusing on identifying urological pain.
RESUMEN
Purpose@#Benign prostatic hyperplasia (BPH) is associated with lower urinary tract symptoms and negatively affects the quality of life. We aimed to investigate the treatment pattern of BPH in South Korea. @*Methods@#Information on treatment modalities and diagnoses of BPH was obtained from the Health Insurance Review and Assessment Service-Aged Patient Sample. Data on BPH patients aged ≥60 years from 2012 to 2016 were obtained. We surveyed the treatment pattern of BPH, including the types of drugs used and surgeries performed, according to the type of institution. @*Results@#In this study, 18,260–24,657 BPH patients treated between 2012 and 2016 were included. The number of patients showed an increasing pattern, and drug therapy was the major treatment method used for BPH (98.77%). Moreover, the pattern of increased pharmacotherapy use for BPH was reinforced by the increasing number of patients. Prescription of α-blockers only was dominant in this cohort (45.7%). Transurethral resection of the prostate (TURP) was the most commonly used surgical treatment for BPH (53.6%), but it showed a decreasing pattern over time. In contrast, holmium laser enucleation of the prostate (HoLEP) showed an increase from 19.4% to 39.7%. @*Conclusions@#The most common treatment for BPH was drug therapy, predominantly only α-blocker therapy. The surgical treatment trend has changed from TURP to HoLEP.
RESUMEN
PURPOSE: To evaluate the relationships between lower urinary tract symptoms (LUTS) and lifestyle factors (physical activity, smoking, alcohol consumption, body mass index, and stress) in Korean men. METHODS: We analyzed the survey results of South Korean men (n=64,439) who were 40 years of age or older among whom interviews were conducted using questionnaires. Trained interviewers performed face-to-face surveys using computer-assisted personal interviewing, the International Prostate Symptom Score (IPSS), and standard questions. We assessed the relationships of lifestyle factors (physical activity, cigarette smoking, alcohol intake, height, weight, and stress) with LUTS. RESULTS: We observed higher IPSS scores in participants who engaged in no exercise (n=46,008 [71.7%], IPSS=3.19±5.36) than in those who engaged in vigorous physical activity (n=10,657 [17.6%], IPSS=2.28±4.15). Former smokers showed higher total, storage, and voiding symptom IPSS scores than current smokers and nonsmokers. Nondrinkers had higher IPSS scores than current alcohol drinkers. In multivariable logistic regression analysis, we detected no relationship between LUTS and current alcohol drinking in the moderate and severe LUTS groups, using the mild LUTS group as a reference (moderate: 0.91; 95% confidence interval [CI], 0.91–0.91; P<0.001, severe: 0.78; 95% CI, 0.78–0.78; P<0.001). Participants with moderate to severe stress showed higher total IPSS scores than those with no or mild stress (3.38±5.77 vs. 2.88±4.90), with significant relationships between stress and LUTS found in the moderate and severe LUTS groups. In logistic regression analysis, stronger relationships were found for storage and voiding symptoms in the moderate and severe stress groups compared to the mild stress group. CONCLUSIONS: A history of smoking, low levels of physical activity, low body mass index, and moderate to severe stress were associated with a greater severity of LUTS. Moderate to severe stress was also related to voiding symptoms. However, there was no association between alcohol intake and LUTS severity.

PURPOSE: This study estimated the prevalence of lower urinary tract symptoms (LUTS) in Korean men and the conditions for being diagnosed with or treated for LUTS/benign prostatic hyperplasia (BPH). METHODS: We analyzed cross-sectional data collected from 69,851 Korean men who were 40 years of age or older and had participated in the Korean Community Health Survey performed in 2011. Interviewers performed face-to-face surveys that included sociodemographic questions, the International Prostate Symptom Score (IPSS), and questions regarding whether the subjects had been diagnosed with or treated for LUTS/BPH. We estimated the prevalence of LUTS and assessed whether the subjects had been diagnosed with or treated for LUTS/BPH. RESULTS: Moderate to severe LUTS, storage symptoms, and voiding symptoms increased with age. The IPSS quality of life score was 1.5±0.004 in the mild LUTS group (n=57,701), 3.3±0.01 in the moderate LUTS group (n=9,203), and 4.3±0.02 in the severe LUTS group (n=2,947) (P<0.0001). The prevalence of moderate to severe LUTS in those who had not been diagnosed with LUTS/BPH was 64.5% (7,847 of 12,150), and the prevalence of moderate to severe LUTS in those who had been diagnosed with LUTS/BPH but had not been treated was 23.5% (2,853 of 12,150). CONCLUSIONS: The severity of LUTS in Korean men increased with age, and the IPSS quality of life score increased with the severity of LUTS. Many Korean men with moderate to severe LUTS had not been diagnosed or treated for LUTS/BPH. Socioeconomic conditions played an important role in health-seeking behavior among patients with LUTS/BPH.

PURPOSE: To assess the impact of intravesical prostatic protrusion (IPP) on the outcomes of robot-assisted laparoscopic prostatectomy (RALP). MATERIALS AND METHODS: The medical records of 1094 men who underwent RALP from January 2007 to March 2013 were analyzed using our database to identify 641 additional men without IPP (non-IPP group). We excluded 259 patients who presented insufficient data and 14 patients who did not have an MRI image. We compared the following parameters: preoperative transrectal ultrasound, prostate specific antigen (PSA), clinicopathologic characteristics, intraoperative characteristics, postoperative oncologic characteristics, minor and major postoperative complications, and continence until postoperative 1 year. IPP grade was stratified by grade into three groups: Grade 1 (IPP≤5 mm), Grade 2 (5 mm10 mm). RESULTS: Of the 821 patients who underwent RALP, 557 (67.8%) experienced continence at postoperative 3 months, 681 (82.9%) at 6 months, and 757 (92.2%) at 12 months. According to IPP grade, there were significant differences in recovering full continence at postoperative 3 months, 6 months, and 12 months (p<0.001). On multivariate analysis, IPP was the most powerful predictor of postoperative continence in patients who underwent RALP (p<0.001). Using a generalized estimating equation model, IPP also was shown to be the most powerful independent variable for postoperative continence in patients who underwent RALP (p<0.001). CONCLUSION: Patients with low-grade IPP have significantly higher chances of recovering full continence. Therefore, the known IPP grade will be helpful during consultations with patients before RALP.

PURPOSE: Few data are available concerning the clinical outcome of abiraterone acetate treatment in patients with metastatic castration-resistant prostate cancer (mCRPC) in terms of the duration of androgen deprivation therapy (ADT) before diagnosis of CRPC. We investigated the clinical efficacy of abiraterone acetate according to the duration of ADT. MATERIALS AND METHODS: We reviewed the medical records of 20 patients with mCRPC who received abiraterone acetate after failure of docetaxel chemotherapy from May 2012 to March 2014 at Seoul National University Bundang Hospital. Clinical factors including prostate-specific antigen (PSA) nadir level, time to PSA nadir, PSA doubling time, PSA response, and modes of progression (PSA, radiologic, clinical) were analyzed. Disease progression was classified according to the Prostate Cancer Working Group 2 criteria. RESULTS: The mean age and PSA value of the entire cohort were 76.0+/-7.2 years and 158.8+/-237.9 ng/mL, respectively. The median follow-up duration was 13.4+/-6.7 months. There were no statistically significant differences in clinical characteristics between patients who received abiraterone acetate with ADT duration or =35 months. There were also no significant differences in terms of PSA progression-free survival, radiologic progression-free survival, and clinical progression-free survival between patients with ADT duration or =35 months. CONCLUSIONS: Although this was a retrospective study with a small sample size, we did not observe any statistically significant differences in the clinical response to abiraterone acetate between mCRPC patients with long ADT duration and those with short ADT duration in terms of disease progression-free survival.

PURPOSE: A low quality clinical trial could produce errors, and these errors could, in turn, distort the results of the clinical trial. To avoid applying distorted results of trials clinically, a quality analysis of clinical trials is needed. MATERIALS AND METHODS: We selected randomized controlled trials (RCTs) about erectile dysfunction (ED) conducted in Korea using Medline and KoreaMed. Quality assessment of selected RCTs was performed using three assessment tools (Jadad scales, van Tulder scale, Cochrane Collaboration Risk of Bias Tool [CCRBT]). RESULTS: The first RCT about ED conducted in Korea was published in 2002. Since 2002, a total of 20 RCTs have been published in medical journals. Among the 20 articles, only 1 article was found to have a low risk of bias according to the CCRBT. On the Jadad scale, there were 17 high quality articles, while 19 articles were assessed as high quality by the VTS. Only 2 RCTs described the randomization method adequately. Only 1 RCT presented allocation concealment. CONCLUSIONS: A low quality clinical trial could produce errors, and these errors could, in turn, distort the results of the clinical trial. To avoid applying distorted results of trials clinically, a quality analysis of clinical trials is needed. The quality of RCTs was found to be high because almost all of the selected RCTs were double blinded studies. However, the quality of RCTs was inadequate with regard to the lack of randomization and absence of allocation concealment. Therefore, performing adequate randomization and adding a description of the appropriate concealment of allocation may improve the quality of RCTs.

PURPOSE: Heat shock protein 27 (HSP27) is known as the material that plays a role in apoptosis control in tumor and cell protection including the immune response, drug tolerance, and so on. In this study, HSP27 expression according to the prostate cancer malignancy level was evaluated, and HSP27 expression was also analyzed after inducing apoptosis by doxazosin treatment of the prostate cancer cell lines. MATERIALS AND METHODS: Reverse transcription polymerase chain reaction (RT-PCR) and immunofluorescence staining of the HSP27 was implemented by the culture of RWPE-1, LNCaP, androgen-independent human prostate cancer cells (PC-3), and TSU-Pr1 cell lines. Analysis was separately conducted in the control group, control vector group treated by dimethyl sulfoxide, and groups treated with 10 microM or 25 microM doxazosin. The expression of HSP27 in RT-PCR and immunofluorescence staining was observed and evaluated after conversion to numerical values. RESULTS: In the RT-PCR results, depending on the cell type, LNCaP, TSU-Pr1 showed the highest HSP27 expression followed by PC-3, LNCaP and RWPE-1 in sequence. After doxazosin treatment, the expression detected by RT-PCR was stronger at a 25-microM doxazosin concentration compared to that at a 10-microM concentration, and the result was similar by immunofluorescence staining. CONCLUSIONS: HSP27 expression increased depending on the prostate cancer cell line. This meant that HSP27 expression was related to the prostate cancer malignancy level. Additionally, the higher the treatment concentration in PC-3 was, the higher the HSP27 expression was. This result showed that doxazosin induced apoptosis of prostate cancer.

PURPOSE: A single surgeon skilled in conventional laparoscopic surgery used laparoendoscopic single-site surgery (LESS) to treat benign urological diseases. This study reports our surgical results and introduces a simple technique with tips based on our experience. MATERIALS AND METHODS: LESS surgery was performed on 116 patients by use of a homemade single-port device composed of an Alexis wound retractor and a powder-free surgical glove. Cases were 44 varicocelectomies (including 8 bilateral cases), 38 renal cyst marsupializations (including 3 bilateral cases), 26 ureterolithotomies (with 1 concomitant ureterolithotomy and contralateral renal cyst marsupialization), 4 prostatic enucleations, and 4 bladder rupture repairs. The mean patient age was 44.43+/-16.46 years (range, 11 to 76 years), and the male-to-female ratio was 87:29. RESULTS: In one ureterolithotomy case, LESS was converted to conventional laparoscopic surgery. The mean operative time was 87.03+/-45.03 minutes, the estimated blood loss was 61.90 ml (range, 0 to 2,000 ml), and the mean hospital stay was 3.03+/-2.12 days. Two patients underwent single-port transvesical enucleation of the prostate (STEP) requiring patient-controlled anesthesia. No patients developed major complications, and all patients were satisfied, with 75.86% expressing a high degree of satisfaction. CONCLUSIONS: We report successful treatment outcomes for LESS in 116 cases of benign urological disease. Our findings suggest that LESS can replace conventional laparoscopy.

Low quality clinical trials have a possibility to have errors in the process of deriving the results and therefore distort the study. Quality assessment of clinical trial is necessary in order to prevent any clinical application erroneous results is important. Randomized controlled trial (RCT) is a design for evaluate the effectiveness of medical procedure. This study was conducted by extracting the RCTs from the original articles published in the Journal of Korean Medical Science (JKMS) from 1986 to 2011 and conducting a qualitative analysis using three types of analysis tools: Jadad scale, van Tulder scale and Cochrane Collaboration risk of bias Tool. To compare the quality of articles of JKMS, quality analysis of the RCTs published in Yonsei Medical Journal (YMJ) and Korean Journal of Internal Medicine was also conducted. In the JKMS, YMJ and Korean Journal of Internal Medicine, the quantitative increase of RCT presented over time was observed but no qualitative improvement of RCT was observed over time. From the results of this study, it is required for the researchers to plan for and perform higher quality studies.

PURPOSE: To evaluate the risk factors for overactive bladder (OAB) in a population aged 40 years and over in the community. MATERIALS AND METHODS: We conducted a community-based survey of OAB in a population aged 40 years and over in Guri City and Yangpyeong County, South Korea, by use of the overactive bladder symptom score (OABSS) questionnaire. A total of 926 subjects were included in the final analysis. The definition of OAB was more than 2 points for the urgency score and 3 points for the sum of scores. In addition, the subjects were asked about age, dwelling place, marital status, educational status, behavioral factors (smoking, drinking, etc), and medical history. Categorical variables were analyzed by using the logistic regression model and were adjusted for age by using the logistic regression model. RESULTS: Overall OAB prevalence was 14.1% (130/926), made up of 49/403 males (12.2%) and 81/523 females (15.5%). OAB prevalence increased with age (p<0.0001). Risk factors for OAB were educational status (age-adjusted p=0.0487), stroke (p=0.0414), osteoporosis (p=0.0208), asthma (p=0.0091), rhinitis (p=0.0008), and cataract. Other factors (dwelling place, marital status, smoking, drinking, hypertension, diabetes, hyperlipidemia, myocardial infarction, angina, tuberculosis, atopic dermatitis, hepatitis B, and depression) were not associated with OAB. CONCLUSIONS: The prevalence of OAB in our study was about 14.1% and the risk factors for OAB were educational status, stroke, osteoporosis, asthma, rhinitis, and cataract. Knowledge of these risk factors may help in the diagnosis and treatment of OAB.

The use of graft materials in bladder mucosa has been examined in animal models, but debate exists over which materials are effective. Intestine has been used as a substitute in augmentation cystoplasty for patients with neuropathic bladder, but serious adverse effects of the operation have occurred in some instances. We report a case of a successful repair of an enterovesical fistula by use of bovine pericardium. The patient has remained well for 2.5 years. We suggest that bovine pericardium may be a suitable option as a bladder substitute.

Most foreign bodies in the lower genitourinary tract are self-inserted via the urethra as the result of exotic impulses, psychometric problems, sexual curiosity, or sexual practice while intoxicated. Diagnosis of these foreign bodies can be done by clinical history, physical examination, and image studies of the patient. The treatment of foreign bodies is determined by their size, location, shape, and mobility. In most cases, minimally invasive procedures such as endoscopic removal are recommended to prevent bladder and urethral injuries. In some cases, however, surgical treatment should be done if the foreign bodies cannot be removed by the endoscopic procedure or further injuries are expected as a result of the endoscopic procedures. Herein we present 2 cases of self-inserted lower genitourinary foreign bodies with a brief review of the literature.

OBJECTIVES: For Parkinsonian patients who had not reacted favorably on drug therapy are good candidate for ventroposterolateral pallidotomy, although not curative. We studied these patients after unilateral pallidotomy, to confirm the effectiveness and safety of this procedure. METHODS: We evaluated the 17 patients with idiopathic Parkinson's diesease who had undergone unilateral posteroventral pallidotomy. All patients responded to levodopa initially. Mean age was 55 years(38-75years), and mean duration of disease was 9.8 years(3-20years). Pre-and postoperative evaluation at 3 month intervals included Unified Parkinson's Disease Rating scale(UPDRS) scoring, Hoehn and Yahr(H and Y) staging, and neuropsychological examinations. RESULTS: Pallidotomy significantly improved parkinsonian symptom(tremor, rigidity, bradykinesia, dyskinesia, sensory symptom). Nine of 10 patients who showed dyskinesia preoperatively significant improvement. The mean dose of levodopa in 9 patients was lowered. The mean H and Y score and UPDRS score were improved in on and/or off time in 15 patients. Among patients who were not improved, one patient worsened, and the others showed no change. The mean overall UPDRS off score changed from 76 preoperatively to 44(33%) at 6 months and from 70 to 52(25%) at 1 year. Transient surgical morbidity was showen in four patients and included dysarthria, hypotonia and confusion. CONCLUSION: We conclude that pallidotomy is safe and effective in patients who have levodopa-reponsive parkinsonism with severe symptom fluctuation. Unilateral pallidotomy also considered helpful to ipsilateral symptom. Unilateral pallidotomy can improve all of parkinsonian's symptom and allow to reduce the levodopa medication. Most of patients show satisfactory results.

Intracerebral hematoma (ICH) after reperfusion procedure in cerebral ischemia is a rare but serious complication. The authors present 4 cases with ICH after reperfusion procedures in cerebral ischemia. First case is ICH after superficial temporal artery-middle cerebral artery anastomosis in moyamoya patient, second case is ICH after graft bypass usuing saphenous vein in traumatic carotid artery injury patient, third case is ICH after intra-arterial urokinase therapy in acute internal carotid artery occlusion and forth case is ICH after temporary clipping to the middle cerebral artery in middle cerebral artery aneurysm surgery. Defective cerebrovascular autoregulation in ischemic brain regions may predispose patients to ICH after reperfusion procedure in cerebral ischemia. The authors suggest reperfusion procedure in ischemia must be executed prudently because of possibility of reperfusion injury including ICH.
