RESUMEN
PURPOSE: To analyze the presentation of mumps and mumps orchitis using the National Health Insurance Service Database (NHISD). MATERIALS AND METHODS: Using information from the NHISD representing all cases of mumps in Korea, data regarding mumps orchitis were analyzed. The International Classification of Diseases, Tenth Revision, and Clinical Modification codes were used for diagnosis. The incidence estimates of the number of mumps cases were analyzed using the Statistical Analysis System (SAS) software. RESULTS: Based on the NHISD, 199,186 people were diagnosed with mumps, and males accounted for 62.3% cases. Teen males accounted for 69,870 cases, the largest number of patients diagnosed with mumps. The annual incidence of mumps increased every year (poisson regression, hazard ratio [HR] 1.026, 95% confidence interval [CI] 1.024-1.027; p<0.025). The risk of mumps was lower in females than that in males (poisson regression, HR 0.594, 95% CI 0.589-0.599; p<0.001). Of the 199,186 patients diagnosed with mumps, 3,872 patients (1.9%) had related complications. Among the mumps complications, the most diagnosed complication was mumps orchitis, which was seen in 41.8% of the males. Mumps orchitis cases accounted for less than 1.5% of the patients with mumps in minors under the age of 20 years and was somewhat higher in 2009 and 2013-2015. CONCLUSIONS: Among the complications related to mumps, meningitis was most common in females, while orchitis was dominant in males. Mumps orchitis also shows periodic outbreaks but is particularly prevalent in adults, which suggests the potential need for additional vaccination against mumps.

PURPOSE: A recent study demonstrated that tamsulosin increased the risk of dementia in patients with benign prostatic hyperplasia. However, this study had a number of limitations. We evaluated the association between α-blockers and dementia in patients with benign prostatic hyperplasia. MATERIALS AND METHODS: From the National Health Insurance Service database we collected and analyzed data on α-blockers and dementia in the entire Korean adult population with benign prostatic hyperplasia between January 2011 and December 2011. These patients were followed until September 2017. We tested the effect of α-blockers on the risk of dementia using propensity score matched Cox proportional hazard regression models and Kaplan-Meier survival analysis. RESULTS: During a mean ± SD followup of 1,580 ± 674.3 days all study inclusion and exclusion criteria were met by 59,263 patients with benign prostatic hyperplasia. In the unadjusted cohort the incidence of dementia in the tamsulosin, doxazosin, terazosin, alfuzosin and no medication cohorts were 17.97%, 18.55%, 20.64%, 17.62% and 22.60%, respectively. After propensity score matching the risk of dementia did not significantly differ in the tamsulosin cohort vs the doxazosin and alfuzosin cohorts (HR 1.038, 95% CI 0.960-1.121 and HR 1.008, 95% CI 0.925-1.098), respectively. Compared to the tamsulosin cohort the terazosin cohort had a higher risk of dementia (HR 1.112, 95% CI 1.052-1.196). However, the risk of dementia was significantly lower in the terazosin cohort than in the no medication cohort. CONCLUSIONS: The study findings indicate that benign prostatic hyperplasia medication is not associated with a risk of dementia by duration of use or by type.

AIMS: Although generally well tolerated, a urodynamic study is an unpleasant and stressful procedure for some patients. This study evaluated the effects of a heating pad on anxiety, pain, and distress during urodynamic studies in female patients with stress urinary incontinence. METHODS: A total of 74 female patients with stress urinary incontinence who underwent a urodynamic study between May 2015 and October 2015 were randomized to either the experimental group using a heating pad (n = 37) or control group (n = 37). In the experimental group, a heating pad was applied on the patient's sacrum during the urodynamic study. All patients completed the State-Trait Anxiety Inventory (20-80) before and after the procedure and assessed their degree of pain and distress after the procedure by the visual analog scale (0-10). Systolic and diastolic blood pressure and pulse rate were also checked before and after the procedure. RESULTS: Demographic characteristics, mean age, procedure duration, pre and post-procedural systolic, and diastolic blood pressures, and pulse rate were statistically similar between the experimental and control groups. The mean State-Trait Anxiety Inventory was significantly lower in the experimental group than in the control group (30.9 ± 7.5 vs 42.5 ± 10.1, P < 0.001). The experimental group showed significantly lower pain and distress scores (Visual Analog Scale, 2.7 ± 1.5, 3.0 ± 1.5) compared with the control group (4.0 ± 1.6, 4.7 ± 2.0, both P < 0.001). CONCLUSIONS: Using a heating pad for female patients with stress urinary incontinence during a urodynamic study is a simple, economical, and effective therapy that enhances patient comfort and decreases anxiety, pain, and distress.

We aimed to compare the short-term outcomes of men who had urodynamic evidence of detrusor underactivity (DU) or detrusor overactivity (DO) of a non-neurogenic etiology as well as bladder outlet obstruction (BOO) and who underwent Holmium Laser Enucleation of the prostate (HoLEP). A database of 322 patients who underwent HoLEP between 2010 and 2014 was analyzed. Patients were classified into three groups according to the results of a preoperative urodynamic study. Preoperative parameters such as International Prostate Symptom Score (IPSS), Quality of Life (QoL) index, IPSS grade, uroflowmetry were compared with postoperative parameters measured at 6 months. There were 138 patients with BOO-only and 89 patients with BOO and detrusor dysfunction including 56 with DO and 33 with DU. The degree of improvement in IPSS-total (BOO: 10.7, DO: 8.3, DU: 7.0; p = 0.023) was greater in the BOO-only group than in the DU group. There were more patients whose IPSS grade improved in the BOO-only group (71%) than in the detrusor dysfunction group (DO: 53.6% and DU: 45.5%). Postoperative IPSS-voiding (4.5 vs 7.0), and Qmax (18 vs 13.7) in the BOO-only group were significantly better than those in the DU group. Additionally, postoperative IPSS-storage (4.7 vs 6.7), and IPSS-total (9.1 vs 12.3) in the BOO-only group were significantly better than in the DO group (all p < 0.05). In conclusion, early surgical management for men with severe LUTS and associated BPH before secondary degeneration occurs may be beneficial for preserving detrusor function and yield better treatment outcomes.

PURPOSE: To evaluate the perioperative, functional, and oncological outcomes of renal cryoablation (RC) of small renal masses (SRMs) performed in Korea University Hospital. MATERIALS AND METHODS: We reviewed an Institutional Review Board-approved database of 70 patients who underwent RC and were followed up for a minimum of 3 months by a single surgeon in Korea University Hospital from August 2007 to May 2014. Among these patients, 68 patients (79 renal masses) were enrolled in our research. We evaluated perioperative, functional, and oncologic outcomes of RC. RESULTS: A total of 68 patients (79 renal masses) underwent RC in our institution. The mean age of the patients was 62.0 years. The mean tumor size was 2.25 cm. Among the 59 patients who underwent laparoscopic surgery, only 1 patient (1.47%) was converted to open surgery. No other perioperative complications occurred. The mean preoperative and 1-month postoperative estimated glomerular filtration ratio (eGFR) were 71.8 and 68.3 mL/min/1.73 m(2), respectively (p=0.19). The mean 1-year postoperative eGFR was 65.0 mL/min/1.73 m(2) (p=0.25). The mean follow-up period was 59.76 months (range, 3-119 months). Local tumor recurrence occurred in eight tumors (15.4%; a total of 52 renal cell carcinomas). Concerning treatment in the patients with recurrence, five patients underwent re-treatment and three patients are under active surveillance. None of the eight patients who experienced local recurrence had additional recurrence or tumor progression during the follow-up period. In our study, the recurrence-free rate was 83.0% and the cancer-specific survival rate was 100%. Moreover, the 5- and 10-year overall survival rates were both 100%. CONCLUSIONS: Long-term experience with RC in our institution demonstrates that RC is a safe and effective treatment for patients with SRMs.

OBJECTIVE: To identify the prognostic factors causing persistent storage symptoms following transurethral resection of the prostate in patients with benign prostatic enlargement (BPE). METHODS: A total of 116 men with symptomatic BPE requiring surgery were enrolled in the study between January 2011 and December 2012. The patients underwent basic clinical evaluations including transrectal ultrasound, International Prostate Symptom Score and urodynamic study. After 6 months, International Prostate Symptom Score and uroflowmetry were rechecked. The definition of persistent storage symptoms was patients with storage scores >7 points. Logistic regression analysis and receiver operating characteristic analysis were conducted. RESULTS: The 116 patients were divided into a persistent storage symptom-positive group (n = 33) and a storage symptom-negative group (n = 83). Multivariate analysis showed that the degrees of worse initial storage symptoms (odds ratio [OR] = 8.32), small bladder capacity (OR = 4.31), impaired detrusor contractility (OR = 2.96) and age (OR = 1.05) were consistently associated with persistent storage symptoms. CONCLUSIONS: This short-term study confirms the positive and consistent correlations between the baseline degree of worse initial storage symptoms, bladder capacity, detrusor contractility and age and the improvement in storage symptoms.

OBJECTIVE: To assess the risk factor that influences bladder stone formation in patients with benign prostatic hyperplasia (BPH). MATERIALS AND METHODS: We reviewed the data of 271 consecutive patients with BPH who underwent transurethral resection of the prostate between January 2008 and December 2012. Patients were classified into 2 groups based on the presence of a bladder stone: Group 1 had a bladder stone and group 2 did not. Univariate analysis was performed to determine the association between the presence of bladder stone and the patients' age, body mass index, International Prostate Symptom Score, total prostate volume (TPV), transitional zone volume, intravesical prostatic protrusion (IPP), uroflow parameters, and urodynamic parameters. RESULTS: The overall rate of bladder stone in patients with BPH was 9.9%. The patients' body mass index, International Prostate Symptom Score, and urodynamic parameters did not significantly differ between the 2 groups. The patients' age, TPV, transitional zone volume, and IPP were all significantly higher and the Qmax was significantly lower in group 1 than that in group 2. Multivariate analysis revealed that age (hazard ratio [HR] = 1.089; P = .020), IPP (HR = 1.145; P <.001), and Qmax (HR = 0.866; P = .019) significantly affected the presence of bladder stone in patients with BPH. A predictive model using logistic regression for bladder stone in BPH patients was defined as follows: probability = 1/[1 + exp (-8.499 + 0.085 (age) + 0.009 (TPV) + 0.136 (IPP) - 0.143 (Qmax))] with area under the curve of 0.850 obtained from the receiver operating characteristic curve analysis. CONCLUSION: This study demonstrated that older age, longer IPP, and lower Qmax are independent factors that associated with the presence of bladder stone in patients with BPH.

To evaluate the role of high-dose dietary zinc in the process of prostate malignancy, 60 Sprague-Dawley rats were randomly divided into four groups: tumor induction with carcinogen and hormone (group 1), oral zinc administration without tumor induction (group 2), oral zinc administration with tumor induction (group 3) and a control without zinc administration or tumor induction (group 4). Zinc was supplied orally in the form of zinc sulfate heptahydrate dissolved in drinking water to groups 2 and 3 for 20 weeks. Although the serum level of zinc measured at 20 weeks was maintained similarly in each group (P = 0.082), intraprostatic zinc concentrations were statistically different. Group 1 prostates contained the least amount of zinc in both the dorsolateral and ventral lobes at levels of 36.3 and 4.8 microg g(-1), respectively. However, in group 3, zinc levels increased in both lobes to 59.3 and 12.1 microg g(-1), respectively, comparable with that of group 4 (54.5 +/- 14.6 and 14.1 +/- 2.4 microg g(-1)). In spite of these increases in zinc concentration, the prevalence of prostate intraepithelial neoplasm was rather increased in group 3 (53.3% and 46.7%) compared with group 1 (33.3% and 33.3%) in both dorsolateral and ventral prostate lobes. Although prostate intraepithelial neoplasm did not develop in any prostate in group 4, zinc administration did induce prostate intraepithelial neoplasm in group 2 (46.7% and 40.0%). Thus, although high dietary zinc increased intraprostatic zinc concentrations, it promoted, instead of preventing, prostate intraepithelial neoplasm in a murine prostate malignancy induction model.

OBJECTIVES: To evaluate the effect of extracorporeal magnetic innervation (ExMI) therapy in children with refractory monosymptomatic nocturnal enuresis (MNE). METHODS: A total of 55 children (34 boys and 21 girls, median age 8.0 years, range 5 to 13) who wetted the bed more than twice per week because of MNE that was refractory to treatment with desmopressin, anticholinergics, and enuretic alarm were assessed prospectively using a voiding diary before and after ExMI, administered once a week for at least 4 weeks with a size-adjusted magnetic chair (each session lasted 20 minutes). RESULTS: After all sessions of ExMI, the mean frequency of nocturnal enuresis decreased significantly to 2.09 +/- 2.47 in all patients (P = 0.04), and the mean functional bladder capacity increased 1.88 times in all patients (P = 0.00). In total, 63.6% of our patients had a nocturnal enuresis frequency of less than 50% after a mean of 6.62 +/- 4.26 ExMI sessions. CONCLUSIONS: From our results, reduced functional bladder capacity might be the main pathophysiologic cause in children with MNE refractory to established treatment. ExMI might have an acute inhibitory effect in these children with refractory MNE by increasing functional bladder capacity. However, long-term follow-up data and controlled study with a sham-stimulation group are necessary to determine the durability of this new therapy for refractory MNE.
