RESUMEN
PURPOSE: We evaluated the change in patient quality of life after the use of a hydrophilic-coated catheter (SpeediCath) in adults requiring intermittent catheterization (IC). METHODS: This was a multicenter, open-label, observational study using the Patient Perception of Intermittent Catheterization (PPIC) questionnaire and the Intermittent Self-Catheterization questionnaire (ISC-Q) and safety at 12 and 24 weeks in adult patients who had already used other type of catheters prior to switching to SpeediCath or in patients undergoing self-IC for the first time for any reason. RESULTS: Among a total of 360 subjects, 215 (59.7%) were women, and the mean age was 62.0±13.2 years. At 24 weeks, the satisfaction rate after using SpeediCath was 84.1%, and 80% of patients responded that they could easily perform IC. In total, 81.6% of patients were willing to continue using SpeediCath. The mean ISC-Q score was 54.90±18.65 at 24 weeks. Men found less interference in their daily life by performing IC than women and found it easier to handle the catheter before it was inserted into the urethra. At week 12, the mean change in ISC-Q was significantly greater in patients <65 years (20.24±23.55) than in those ≥65 years (7.57±27.70, P=0.049), but there was no difference at 24 weeks. The most common adverse events were urinary tract infection in 9.72%, gross hematuria in 2.78%, and urethral pain in 1.39%. CONCLUSION: The use of a SpeediCath provided good quality of life for patients who needed self-IC regardless of age or sex.
RESUMEN
PURPOSE: With a rapidly aging population in Korea, the number of patients with lower urinary tract symptoms is increasing. Therefore, it is important to determine the current extent of incontinence among Korean women to establish future plans. We attempted to create reference materials for organizing public relations and educational activities by investigating the effect of age on incontinence and quality of life in women. MATERIALS AND METHODS: The participants comprised women aged 30 years and older who visited a tertiary center for health screening from September 1 to October 31, 2016. The survey included a questionnaire consisting of 12 questions that took approximately 10 minutes to complete. We analyzed the responses and assessed the prevalence of the disease and its rate of recognition. RESULTS: A total of 509 women completed the survey. Irrespective of age, 76.8% of all respondents were aware of urinary incontinence (UI) and 57.4% of the women exhibited lower urinary tract symptoms. The most prevalent symptom was UI (45.8%), and the incidence rates of stress and urge UI were identified as 33.6% and 12.2%, respectively. Only 8.0% of the women had visited a hospital; 38.3% had awaited spontaneous symptom improvement. Many participants (61.2%) answered that a urology clinic is suitable for treating UI, while 58.9% chose a gynecology clinic. CONCLUSIONS: Our study showed that more than 75% of women are aware of UI, but their perception of the disease mechanism and treatment options was low. We suggest that continuous education and publicity are necessary.

Purpose: To evaluate the categories of nocturia and relationships with the international prostate symptom score (IPSS) in Korean men with lower urinary tract symptoms (LUTS) accompanying nocturia. Materials and Methods: Five hundred twenty-one male patients from five different hospitals, aged ≥18 years, were included. The 3-day frequency volume chart was used to identify nocturia. We also used the IPSS and The International Consultation on Incontinence Modular Questionnaire-Nocturia (ICIQ-N) module to verify the correlation between nocturia and quality of life. Results: The distribution of nocturia events varied from 1 to 11, and 2 nocturia events were most prevalent (48.4%). Across the various numbers of nocturia events, the mean age, first sleep period, functional bladder capacity (FBC), nocturnal polyuria index (NPI), nocturia index (NI), predicted number of nightly voids, and nocturnal bladder capacity index (NBCI) were statistically different. Patients with pure nocturnal polyuria showed different night lengths, nocturnal urine volume, FBC, NPI, NI, and predicted number of nightly voids than those without nocturnal polyuria. Patients with severely reduced NBCI were prominent in the IPSS >20 group, and the degree of vexation increased with the number of nocturia events. The IPSS storage symptom score and ICIQ-N symptom score positively correlated with nocturia events. Conclusions: In Korean male LUTS patients with nocturia, mixed-type nocturia was prominent, and patients with a high IPSS had a much poorer sleep quality than those with a low IPSS.

PURPOSE: To evaluate the significance of preoperative and follow-up neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) as prognostic factors for recurrence in patients with non-metastatic clear cell renal cell carcinoma (NMCCRCC). MATERIALS AND METHODS: We retrospectively reviewed the medical records of 309 patients with NMCCRCC who underwent radical or partial nephrectomy. The prognostic significance of various clinicopathological variables, preoperative NLR (pNLR) and PLR (pPLR), and NLR and PLR at recurrence or quasi-recurrence (rNLR and rPLR) for recurrence-free survival (RFS) was analyzed. RESULTS: At mean follow-up of 93 months, 44 patients (14.2%) developed recurrence. In the univariate analysis, clinical presentation, tumor size, pathologic tumor stage, Fuhrman grade, pNLR, pPLR and rNLR were significant prognostic factors for RFS. In the multivariate analysis using pNLR and pPLR as continuous variables, tumor size, pathologic tumor stage and pPLR were independent prognostic factors for RFS. In the multivariate analysis using pNLR and pPLR as dichotomous variables, tumor size, pathologic tumor stage, Fuhrman grade and pNLR ≥1.7 were independent prognostic factors for RFS. In multivariate analyses using rNLR and rPLR, only tumor size and pathologic tumor stage were independent prognostic factors for RFS. In a subset of patients with recurrence or at least 42 months follow-up without recurrence, rNLR ≥1.9 was significantly associated with worse RFS, albeit without independent significance. CONCLUSIONS: pNLR and pPLR are independent prognostic factors for RFS in patients with NMCCRCC. We propose that postoperative follow-up NLR of 1.9 and higher with one or more adverse clinicopathological factors should prompt radiologic evaluation for possible metastasis.

OBJECTIVES: To analyse actual long-term medical treatment of benign prostatic hyperplasia (BPH) and compare the incurred cost with that of patients with BPH who underwent early surgery. PATIENTS AND METHODS: Patients who were first diagnosed with BPH from 1 January 2008 to 31 December 2010 were identified using the Clinical Data Warehouse. Hospital billing data generated by the electronic hospital management system were collected until December 2015. For outpatient care, only procedures, materials and drugs directly related to the management of BPH were selected for the analysis. For inpatient care, all procedures, materials and drugs ordered on dates with continuity with BPH surgery date were included. The primary endpoint of the study was the total treatment-related direct costs of patients undergoing a long-term curative medical therapy for BPH (Group 1), which was arbitrarily defined as any medical therapy including a 5α-reductase inhibitor with a minimum medication possession ratio of 0.5 during ≥5 consecutive years, or ≥1 year until BPH surgery due to medical therapy failure. In all, 70 patients who underwent BPH surgery at <1 year of initial visit served as controls (Group 2). RESULTS: Amongst 137 patients in the Group 1, four patients underwent BPH surgery at a median of 57.8 months after the initial visit (2.9%). At a median follow-up of 76 months, the mean total treatment cost was significantly higher in Group 1 than in Group 2 ($3987 vs $3036 [USA dollars], P < 0.001). Similarly, the mean 'out-of-pocket' cost was significantly higher in Group 1 than in Group 2 ($1742 vs $1436, P = 0.005). When a linear increment of annual BPH treatment cost is assumed for Group 1 and all costs are assumed to be produced within the first year for Group 2, the total and out-of-pocket costs became equal at the end of the fifth year of medical treatment. For both total and out-of-pocket costs, medication-related costs occupied the largest proportion, exceeding half of the costs. CONCLUSIONS: We suggest patient counselling at the beginning of BPH treatment should include the likelihood that the cumulative out-of-pocket cost at 5 years of continuous medication will exceed that of early surgery. Our cost study using hospital billing data extractable from the electronic hospital management system may be a good model for cost studies that could provide valuable information to health providers and payers.

OBJECTIVE: To evaluate the efficacy and safety of silodosin on nocturia in patients with benign prostatic hyperplasia (BPH). MATERIALS AND METHODS: This was a 12-week, single-arm, open-label, prospective, multicenter study. The study included men aged 50 years or older with nocturia (≥2 events/night) based on a voiding diary, an International Prostate Symptom Score (IPSS) ≥8, and a quality of life score ≥3. Enrolled patients received 8 mg of silodosin once daily for 12 weeks. We evaluated changes in the mean number of nocturia episodes (using a voiding diary) from baseline to the final assessment. Safety assessments included the rate of adverse events and adverse drug reactions. RESULTS: There were 118 patients included in the safety evaluation analysis, and 112 patients in the full analysis set group. The number of nocturia episodes decreased significantly after 12 weeks of treatment with silodosin (-1.12 ± 1.05, P < .0001). The secondary efficacy variables, including IPSS, overactive bladder symptom score and International Consultation on Incontinence Questionnaire-Nocturia score, also improved with treatment (P < .0001). There were abnormal drug reactions in 11.8% of patients. The most common adverse drug reaction was an ejaculatory disorder (7.6%). There were no significant adverse drug reactions reported. CONCLUSION: Silodosin was found to be safe and effective in the treatment of nocturia in patients with BPH.

PURPOSE: To compare the clinical efficacy of anticholinergics for managing diabetes mellitus-associated overactive bladder (DM OAB) versus idiopathic overactive bladder (OAB) in Korean women. METHODS: We conducted a multicenter, prospective, parallel-group, open-label, 12-week study. Women (20-65 years old) with OAB symptoms for over 3 months were assigned to the DM OAB and idiopathic OAB groups. Changes in the Overactive Bladder Symptom Score (OABSS), urgency, urinary urgency incontinence, nocturia, daytime frequency according to a voiding diary, uroflowmetry, and postvoid residual urine volume (PVR) at the first visit (V1), week 4 (V2), and week 12 (V3) were compared. RESULTS: No significant difference was found between the baseline patient characteristics of the DM OAB and idiopathic OAB groups. Treatment with solifenacin was associated with improvements in urgency, urinary urgency incontinence, nocturia, frequency according to a voiding diary, and the total OABSS between V1 and V2 and between V1 and V3. Moreover, a significant improvement in urgency and urge incontinence was found between V2 and V3 in the DM OAB group. However, no significant changes were found in any other parameters. There were no significant differences between the DM OAB group and the idiopathic OAB group except for urgency and urge incontinence at V2 (3.71 vs. 2.28 and 0.47 vs. 0.32, respectively). CONCLUSIONS: The patients who received solifenacin demonstrated improved urgency, urinary urgency incontinence, nocturia, frequency according to a voiding diary, and total OABSS. Management with solifenacin was equally effective for both DM-related OAB and idiopathic OAB.
RESUMEN
Purpose: To determine changes in autonomic nervous system activity after treatment in men with lower urinary tract symptoms (LUTS), we evaluated changes in patients' symptoms, uroflowmetry, and heart rate variability (HRV) after treatment with alpha-blockers for 12 weeks. Materials and Methods: Ninety-five men who had LUTS (International Prostate Symptom Score [IPSS] ≥8) were included in this study. We divided them into two groups on the basis of a low frequency/high frequency (LF/HF) ratio of 1.6. After treatment with Xatral XL (Handok Inc., Korea) 10 mg for 3 months, we rechecked their IPSS, uroflowmetry, HRV and compared these with the baseline measurements. Results: Fifty-four men were assigned to the low LF/HF group (group A: LF/HF ≤1.6) and 41 men to the high LF/HF group (group B: LF/HF >1.6). At baseline and 12 weeks, none of the parameters differed significantly between the groups except for HF, which is one of the parameters of HRV. IPSS, the IPSS-voiding subscore, and the IPSS-storage subscore decreased and maximal uroflow increased significantly after 12 weeks of treatment. Whereas the baseline LF/HF ratio increased from 0.89±0.407 to 1.80±1.804 after treatment in group A, it decreased from 3.93±5.471 to 1.79±1.153 in group B. Conclusions: The efficacies of Xatral XL were clear in both groups. We found that the LF/HF ratio in the two groups merged to a value of approximately 1.79 after treatment. We suggest that this could be a clue to the importance of balance in autonomic nervous system activity in men with LUTS.

OBJECTIVES: The aim of this study was to evaluate the pattern of tailoring and efficacy of several types of pharmacotherapy in male LUTS. METHODS: Prospectively 404 male subjects were included who were over 40 years old, had at least 3 months symptom duration, and 12 or higher international prostate symptom score (IPSS). Subjects were treated with several types of pharmacotherapy for 6 months and were evaluated with IPSS/QoL at every follow-up. Subjects were subdivided into storage (44%), nocturia (18.5%), and voiding symptom (37.5%) groups according to the most bothersome symptom. RESULTS: At 6 months, 188 subjects (46.5%) completed the study. The mean age was 64.2±8.5 years, and symptom duration was 30.6±32.6 months. PSA was 2.98±7.96 ng/mL, and prostate size was 32.8±14.2 cc. IPSS continually decreased from baseline (18.7) to last follow-up (10.8). Combination therapy increased from 33.0% to 52.7% at last follow-up (P=.006). However, there was no difference of IPSS changes between combination and monotherapy groups (P>.05). Only antimuscarinic prescription significantly increased from 15.4% to 28.2% (P=.004). Mean number of visits to the clinic was 3.6±1.3 and the number of treatment changes was 0.31±0.47. The nocturia (0.47±0.51) group changed treatment more than voiding group (0.21±0.41, P=.003). However, the voiding group (-9.4) had significantly more improvement than e storage (-6.4) and nocturia (-7.8) groups (P=.011). CONCLUSIONS: Male LUTS continually improved over 6 months with customised treatment. Pharmacotherapy for male LUTS should be tailored by symptom type and alteration of symptoms during treatment.

INTRODUCTION AND HYPOTHESIS: The objective was to investigate the expression of endothelial nitric oxide synthase (eNOS) and phosphodiesterase (PDE) 5 in vaginal tissue of premenopausal women experiencing stress urinary incontinence (SUI) with and without sexual dysfunction. METHODS: Women presenting for treatment of SUI were screened using the Female Sexual Function Index (FSFI) and 10 were selected who met the criteria for female sexual dysfunction (FSD) and 10 asymptomatic controls. Vaginal tissue specimens were obtained from those premenopausal women aged ≥40 years who had had sexual activity ≥2 times every month for the last 6 months and who were scheduled to undergo surgery for SUI. FSD criteria was FSFI scores <18 and arousal domain scores <3. The control group had FSFI scores ≥26 and individual domain scores ≥4. The expressions of eNOS and PDE 5 were compared in the two groups using immunofluorescence staining and western blotting. RESULTS: The mean total FSFI scores were 30.4 ± 2.6 and 15.3 ± 2.3 in the control and FSD groups respectively. In immunofluorescence staining, eNOS and PDE5 were localized in the vaginal epithelium. In western blotting, the expressions of eNOS and PDE5 were significantly lower in the FSD group than in the control group (p = 0.003 and p = 0.038 respectively). CONCLUSIONS: eNOS and PDE5 in the vagina may play important roles in the pathophysiology of FSD.

PURPOSE: Complaints from spinal cord injury (SCI) patients are typically related to physical disability affecting activities of daily life. However, difficulties with voiding and defecation and/or sexual function can also be major concerns. The general population and even physicians are generally unaware of these complaints; therefore, this study focuses on surveying SCI patients regarding challenges that are faced in daily life. METHODS: A questionnaire was administered randomly and anonymously to SCI patients who visited the Korea Spinal Cord Injury Association and several rehabilitation hospitals in the Republic of Korea in 2013. All participants gave their consent prior to filling out the questionnaire. RESULTS: A total of 299 patients answered the questionnaire; the male to female ratio was 5.8:1 and common vectors for injury were motor vehicle accidents, industrial accidents, and falling down. Of the 169 patients who answered the 'most troublesome' and 'wish would improve' complaints questionnaire properly, urinary problems were most common, specifically incontinence and urinary tract infection. Among all patients, 67% were using clean intermittent catheterization, 63% were taking voiding-related medications, 83% had sexual desires, and among the 122 patients who did not have offspring, 27% had future plans for children. CONCLUSIONS: From this questionnaire, we discovered that SCI patients in the South Korea suffer not only from physical disability but also many other quality-of-life-related problems. When managing SCI patients, physicians should show greater concern and educate patients about problems related to voiding and sexual activity, rather than just physical disability.
RESUMEN
PURPOSE: In this study, we compared the treatment outcomes for an α-blocker between 2 groups of men, one with high sympathetic activity (HSA) and another with low sympathetic activity (LSA) or normal sympathetic activity. METHODS: A total of 159 men (≥50 years of age) with lower urinary tract symptoms resulting from benign prostatic hyperplasia were analyzed. We assigned patients to groups according to their sympathetic activity, which was evaluated by heart ratevariability measurements. HSA was defined as a low frequency/high frequency ratio greater than 1.6. All patients received 10mg of alfuzosin once a day for 12 weeks. The primary end point was a change in the total International Prostate SymptomScore (IPSS) at 12 weeks from baseline. RESULTS: Sixty-seven men were assigned to the HSA group and 92 men were assigned to the LSA group. The baseline characteristics were not significantly different between the 2 groups, and the response to alfuzosin was good in both groups. Themean total IPSS change was not different between the groups. Both groups were not significantly different with respect to the changes in maximal flow rate, IPSS voiding or storage symptom subscores, quality of life, and rates of adverse drug events. TheHSA group showed a similar willingness to continue treatment compared to the LSA group, although their treatment satisfaction rating was lower. CONCLUSIONS: The therapeutic effects of alfuzosin did not differ in regards to the differences in sympathetic activity, but treatment satisfaction ratings were lower in the HSA group.
RESUMEN
OBJECTIVE: To evaluate the efficacy, complications, and managements of the readjustable midurethral sling (Remeex system) for the treatment of recurrent stress urinary incontinence (SUI) after previous anti-incontinence surgeries or intrinsic sphincter deficiency (ISD). METHODS: Between March 2008 and February 2012, 102 women, who presented with previous failed surgery or ISD, were treated with the Remeex system at 4 different institutions. We retrospectively reviewed medical history, physical examination, urodynamic study, postvoiding residual volume, and/or 1-hour pad test of the patients. Surgical outcomes were evaluated using the Severity Index for Urinary Incontinence. The degree of patient satisfaction was assessed, and all complications were classified according to the modified Clavien classification system. RESULTS: After a mean follow-up of 27.6 months (range, 14-56 months), 91 patients (89.2%) were cured and 6 patients (5.9%) were improved. The patient's satisfaction rate was 87.2% (89 of 102 patients). Overall, 41 patients (40.2%) experienced 53 complications; 15 patients (14.7%) presented de novo urgency, which was properly managed with anticholinergics, and 14 patients (13.7%) underwent delayed sling readjustment for recurrent SUI (n = 13) and urinary retention (n = 1) during follow-up. Among 6 patients (5.9%) with wound infection, 4 patients were successfully treated by daily dressing with antibiotics, and 2 patients underwent removal of the Remeex system owing to intractable infection. Most complications were classified as grade 1 (54.8%) or 2 (15.1%) and were successfully treated with minimal conservative measures. CONCLUSION: The Remeex system is a valuable adjunct for recurrent SUI after previous anti-incontinence surgeries or ISD, considering most complications are Clavien grade I or II.

INTRODUCTION: Urinary incontinence (UI) and Alzheimer's disease (AD) are common in the elderly population and have increased rapidly in recent decades. This study aimed to evaluate the prevalence of UI and determine the neuropsychological characteristics of patients with AD and UI. METHODS: A total of 464 patients with probable AD were recruited, and the prevalence and type of UI were evaluated. Neuropsychological evaluation was assessed using the Mini-Mental Status Examination, Clinical Dementia Rating, Clinical Dementia Rating-Sum of Boxes, Global Deterioration Scale, Barthel Activities of Daily Living and Instrumental Activities of Daily Living. RESULTS: The prevalence of UI in patients with AD was 24.8% (men 29.6%, women 23.0%). The two most common types of UI were urge incontinence (44.3%) and functional incontinence (25.3%). UI in patients with Alzheimer's disease was statistically significantly associated with Clinical Dementia Rating-Sum of Boxes (OR 1.56, 95% CI 1.21-2.01) and Barthel Activities of Daily Living (OR 1.34, 95%CI 1.22-1.47) after adjustment for different covariates. DISCUSSION: UI commonly occurred in patients with AD. The Clinical Dementia Rating-Sum of Boxes and Barthel Activities of Daily Living could be potential predictors for UI in patients with AD.

PURPOSE: Dry mouth is among the most common side effects of antimuscarinic therapy. This study evaluated the drug-related change in dry mouth after the solifenacin treatment and the impact of dry mouth on the drug efficacy against overactive bladder syndrome (OAB). MATERIALS AND METHODS: OAB patients (n = 331) were enrolled in a prospective, multicenter, 8-week observational study of solifenacin treatment. Participants were >20 years of age and presented with OAB symptoms for ≥3 months, a total overactive bladder symptom score (OABSS) of ≥3, and an urgency score of ≥2. Primary endpoints were changes in dry mouth according to baseline dry mouth status using Xerostomia Inventory (XI) and the effect of dry mouth to the drug efficacy according to improvements in the OABSS. RESULTS AND CONCLUSIONS: Three hundred and thirty-three patients were initially screened for the study, with 331 actually enrolled. One hundred and ninety-four patients completed the study. Mean total XI scores increased by 2.8 points in the entire patient population, with larger increases for patients stratified into the non-dry mouth group (NDG) versus the dry mouth group (DG) (4.0 vs. 1.9, p = 0.015) at study baseline. Mean total OABSSs decreased by 3.2 points, with no significant differences between the NDG and the DG (-3.4 vs. -3.0 points, p = 0.578). The dry mouth aggravated in 71 patients (29.2 %) (NDG 30.1 % and DG 27.1 %), but only 10/331 individuals (3.0 %) stopped medication due to xerostomia. Dry mouth progressed in approximately 30 % of the OAB patients, regardless of its presence before solifenacin treatment. However, OAB symptoms were well relieved by solifenacin, and the adverse influence of dry mouth on drug persistence was low.

PURPOSE: In this study, we examined the difference in the treatment efficacy depending on the sympathetic activity in men with lower urinary tract symptoms (LUTS). METHODS: In the current single-center, retrospective study, we evaluated a total of 66 male patients aged 40-70 years of age, presenting with LUTS, whose International Prostate Symptom Score (IPSS) exceeded 8 points. They had a past 3-month history of taking alfuzosin XL, and their heart rate variability (HRV) was measured before and after the treatment. In addition, we also recruited 39 healthy volunteers who visited a health promotion center for a regular medical check-up. They were aged between 40 and 70 years and had an IPSS of <8 points. We divided the patients with LUTS into two groups: the groups A and B, based on a low frequency/high frequency (LF/HF) ratio of 1.7, which was the mean value of the LF/HF ratio in the healthy volunteers. After a 3-month treatment with alfuzosin XL, we compared treatment outcomes, based on the IPSS and peak urine flow rate, between the two groups. RESULTS: A 3-month treatment with alfuzosin XL, comprising the measurement of the HRV, was performed for the 23 patients of the group A (23/38) and 17 of the group B (17/28). After a 3-month treatment with alfuzosin XL, total IPSS and IPSS questionnaire 2 and 5 were significantly lower in the group A as compared with the group B. But this was not seen in the group B. Furthermore, there were no significant differences in other parameters, such as maximal flow rate and IPSS storage subscore, between the two groups. CONCLUSIONS: Our results indicate that the treatment efficacy was lower in patients with sympathetic hyperactivity as compared with those with sympathetic hypoactivity. Thus, our results will provide a basis for further studies to clarify causes of LUTS in a clinical setting.
RESUMEN
PURPOSE: Nationwide database regarding stress urinary incontinence (SUI) is important for evaluating treatment patterns for SUI and for establishing appropriate national policies regarding SUI management. The purpose of this present study was to investigate surgical treatment patterns for women with SUI and analyze the current status of SUI management in Korea by using a nationwide database. METHODS: Data used for investigating the surgical trends and changes in Korea were retrieved from the Health Insurance Review & Assessment Service from 2008 to 2011. RESULTS: The number of surgical cases of SUI decreased continuously from 2008 to 2011. The proportion of transvaginal surgery using a midurethral sling increased continuously. Sling procedures were most commonly performed for women in their 40s followed by women in their 50s. Transvaginal surgery using a single sling or a readjustable sling was performed from 5.6% to 6.1%, which showed no significant change in the number of surgical cases. CONCLUSIONS: There is a growing need for an appropriate national welfare policy and budget to care for aged and super-aged women in Korea. The early detection and intervention of silent SUI should be actively considered as an important preventive strategy to improve the quality of life in younger women.
RESUMEN
PURPOSE: The aims of this study were to investigate the efficacy of combining the systematized behavioral modification program (SBMP) with desmopressin therapy and to compare this with desmopressin monotherapy in the treatment of nocturnal polyuria (NPU). METHODS: Patients were randomized at 8 centers to receive desmopressin monotherapy (group A) or combination therapy, comprising desmopressin and the SBMP (group B). Nocturia was defined as an average of 2 or more nightly voids. The primary endpoint was a change in the mean number of nocturnal voids from baseline during the 3-month treatment period. The secondary endpoints were changes in the bladder diary parameters and questionnaires scores, and improvements in self-perception for nocturia. RESULTS: A total of 200 patients were screened and 76 were excluded from the study, because they failed the screening process. A total of 124 patients were randomized to receive treatment, with group A comprising 68 patients and group B comprising 56 patients. The patients' characteristics were similar between the groups. Nocturnal voids showed a greater decline in group B (-1.5) compared with group A (-1.2), a difference that was not statistically significant. Significant differences were observed between groups A and B with respect to the NPU index (0.37 vs. 0.29, P=0.028), the change in the maximal bladder capacity (-41.3 mL vs. 13.3 mL, P<0.001), and the rate of patients lost to follow up (10.3% [7/68] vs. 0% [0/56], P=0.016). Self-perception for nocturia significantly improved in both groups. CONCLUSIONS: Combination treatment did not have any additional benefits in relation to reducing nocturnal voids in patients with NPU; however, combination therapy is helpful because it increases the maximal bladder capacity and decreases the NPI. Furthermore, combination therapy increased the persistence of desmopressin in patients with NPU.
RESUMEN
PURPOSE: To investigate whether hospitalization influences serum prostate-specific antigen (PSA) values. MATERIALS AND METHODS: Transrectal ultrasound-guided prostate biopsies were performed for detecting prostate cancer in 2,017 patients between February 2001 and April 2011 at Ajou University Hospital. Of those patients, 416 patients who were hospitalized for prostate biopsies, whose serum PSA values were measured at the outpatient department within 1 month of admission and also just after admission, and who had negative prostate biopsy results were included in the present study. We retrospectively reviewed the data of the 416 patients and compared the serum PSA values measured in the outpatient department with those measured during hospitalization. RESULTS: Among all 416 patients, the interval between the two PSA measurements was 22.2 days (range, 3 to 30 days) and the prostate size measured by transrectal ultrasonography was 53.63 mL (range, 12.8 to 197.9 mL). Among all patients, mean serum PSA levels measured during hospitalization were significantly lower than those measured in the outpatient department (6.69 ng/mL vs. 8.01 ng/mL, p<0.001). When stratified according to age, the presence or absence of chronic prostatitis in the biopsy pathology, serum PSA levels, and prostate size, the serum PSA levels measured during hospitalization were significantly lower than those measured in the outpatient department in all subgroups, except in cases aged 20 to 39 years and those with PSA <4 ng/mL, in whom no significant differences were shown. CONCLUSIONS: Hospitalization decreases serum PSA values compared with those measured on an outpatient basis in patients with benign prostatic diseases. Therefore, serum PSA values should be checked on an outpatient basis for serial monitoring.
RESUMEN
PURPOSE: Thanks to advancements in surgical techniques and instruments, many surgical modalities have been developed to replace transurethral resection of the prostate (TURP). However, TURP remains the gold standard for the surgical treatment of benign prostatic hyperplasia (BPH). We conducted a meta-analysis on the efficacy and safety of minimally invasive surgical therapies for BPH compared with TURP. METHODS: This meta-analysis used a Medline search assessing the period from 1997 to 2011. A total of 784 randomized controlled trials were identified in an electronic search. Among the 784 articles, 36 randomized controlled trials that provided the highest level of evidence (level 1b) were included in the meta-analysis. We also conducted a quality analysis of selected articles. RESULTS: Only 2 articles (5.56%) were assessed as having a low risk of bias by use of the Cochrane collaboration risk of bias tool. On the other hand, by use of the Jadad scale, there were 26 high-quality articles (72.22%). Furthermore, 28 articles (77.78%) were assessed as high-quality articles by use of the van Tulder scale. Holmium laser enucleation of the prostate (HoLEP) showed the highest reduction of the International Prostate Symptom Score compared with TURP (P<0.0001). Bipolar TURP, bipolar transurethral vaporization of the prostate, HoLEP, and open prostatectomy showed superior outcome in postvoid residual urine volume and maximum flow rate. The intraoperative complications of the minimally invasive surgeries had no statistically significant inferior outcomes compared with TURP. Also, there were no statistically significant differences in any of the modalities compared with TURP. CONCLUSIONS: The selection of an appropriate surgical modality for BPH should be assessed by fully understanding each patient's clinical conditions.
