ABSTRACT

The prospective study is to investigate the associations between serum testosterone levels and LUTS among middle-aged men ≥40 years receiving health check-up. Lower urinary tract symptoms were evaluated by the self-administered International Prostate Symptom Score questionnaire. Serum prostate specific antigen and total testosterone level were checked in all subjects. A total of 1752 men were enrolled into the study. The mean age was 55.6 ± 9.7 years. All study subjects were stratified into low, medium and high testosterone levels by two cut-off, 3.0 and 4.11 ng/mL. We found that testosterone levels were significantly associated with metabolic syndrome and body fat components. Compared to those with low testosterone levels, subjects with high and medium testosterone had a significantly higher IPSS (5.84 ± 5.55 vs 6.71 ± 5.68 and 6.34 ± 5.66, p = 0.032) and storage score (2.76 ± 2.29 vs 3.20 ± 2.49 and 2.90 ± 2.49; p = 0.009), and a more moderate/severe LUTS (IPSS ≧ 8) (26.5% vs 35.7% and 29.9%; p = 0.002). Multivariate analyses showed that high vs low testosterone levels (OR, 1.76; 95% CI, 1.26-2.45) and prostate volume ≧25 vs <25 mL (OR, 1.38; 95% CI, 1.04-1.82) significantly associated with the presence of moderate/severe LUTS. Pearson correlation analyses showed significantly positive correlations between testosterone level and IPSS in whole study sample (Pearson correlation coefficient, 0.066; p < 0.01) and in the subgroup of moderate/severe LUTS (Pearson correlation coefficient, 0.038; p < 0.05). In conclusion, high testosterone and prostate volume adversely impacted LUTS in our target population.

ABSTRACT

OBJECTIVES: To investigate the impact of metabolic components and body composition indices on prostate volume (PV) in a population of middle-aged men receiving health check-ups. METHODS: Six hundred and sixteen men receiving health assessments were stratified to large and small prostates based on the cut-off of median PV. Their demographic data, health history, and international prostate symptoms scores (IPSS) were collected. Metabolic components and body composition indices were compared between subjects with large and small prostates. Moreover, the correlations between these parameters and PV were analyzed by multivariate logistic regression. RESULTS: The median PV was 27 mL and mean age was 54.8 years. Subjects with large PV were older (56.5 vs. 52.7 years) and had higher serum prostate specific antigen (PSA) level (1.73 vs. 0.96 ng/mL), higher IPSS score (8.37 vs. 6.16), and higher body fat, body mass, and waist circumference (all p<0.05). In multivariate analysis, age (OR, 2.45; 95%CI, 1.74-3.45), serum PSA (OR, 2.75; 95%CI, 1.96-3.86), waist circumference (OR, 1.45; 95%CI, 1.02-2.07), fatness (OR, 1.47; 95%CI, 1.04-2.09), and body fat mass (OR, 1.43; 95%CI, 1.00-2.03) were significantly correlated with PV of study subjects. In subgroup analysis, raised waist circumference (OR, 1.89; 95%CI, 1.00-3.59) was the independent predictor of PV in subjects with bothersome lower urinary tract symptoms. CONCLUSIONS: Several metabolic components and body composition indices are significantly associated with PV of middle-aged men, including raised waist circumference, fatness, and body fat mass. Raised waist circumference is the only independent predictor of PV in middle-aged men with bothersome LUTS.

ABSTRACT

PURPOSE: To evaluate the effectiveness of presence of desmopressin in treating primary enuresis (PE) for children with attention deficit-hyperactivity disorder (ADHD) symptoms. MATERIALS AND METHODS: Children aged from 5 to 12 years with the chief complaint of PE treated with desmopressin were enrolled in pediatric urology clinics. The parent-reported SNAP-IV questionnaire was used to evaluate ADHD symptoms (cut-off value: 90th percentile). Voiding symptoms were assessed by the Dysfunctional Voiding Scoring System (DVSS) questionnaire. The responses to desmopressin were analyzed in children with and without ADHD symptoms. RESULTS: The study sample comprised 68 children; 27 (39.7%) presented with ADHD symptoms and 41 (60.3%) with non-ADHD symptoms. The children collected from a tertiary referral center may explain the high prevalence of ADHD symptoms in the present study. The total DVSS score in the ADHD symptoms group was significantly higher than in the non-ADHD symptoms group (7.72 versus 5.65, P=0.05). In the ADHD symptoms group, there were significantly higher score in the "pee 1-2 times/day" and "can't wait" subscales of DVSS and lower sleep quality based on the Pediatric Sleep Quality questionnaire, as well as significantly lower peak flow rate and voided volume. The responses to desmopressin for enuresis were comparable between children with ADHD and non-ADHD symptoms. CONCLUSIONS: Approximately 39.7% of PE children presented with ADHD symptoms at urologic clinics. PE children with ADHD symptoms had higher risk of daytime LUTS and comparable response to desmopressin treatment for PE. To evaluate ADHD symptoms and daytime voiding symptoms is important in children with PE.

ABSTRACT

BACKGROUND/PURPOSE: To evaluate the effectiveness and safety of high-power 120W Greenlight HPS laser (HPS) and compare the results to transurethral resection of the prostate (TURP), and define a subgroup of patients who had better symptom score improvement after HPS. METHODS: One hundred and twenty-five patients who underwent surgery for benign prostatic hyperplasia (BPH) (61 HPS and 64 TURP) were retrospectively followed. Improvements of International Prostate Symptom Score (IPSS), quality of life score (QoL), maximum flow rate (Qmax) and post-void residual (PVR) were assessed at 4 weeks after the procedures. Potential covariates including age, body mass index (BMI), prostate volume (PV) and serum prostate-specific antigen (PSA) were defined and further subgroup analyses were utilized. RESULTS: The HPS group had a significantly higher education level, annual household income and larger prostate size. Compared with TURP, HPS resulted in comparable IPSS, QoL, Qmax and PVR improvements, but shorter hospitalization duration, serum hemoglobin loss and blood transfusion rate. Subgroup analyses showed that men in the HPS group were younger (age<76 years), had higher BMI (≥24kg/m(2)) and greater adjusted IPSS and QoL improvements than men in the TURP group. CONCLUSION: HPS offered adequate effectiveness for symptomatic BPH versus TURP and was advantageous with regard to operative safety. Patients who are younger and have higher BMI may achieve better improvements with HPS than with TURP. Further long-term follow-up study is warranted.

ABSTRACT

BACKGROUND/PURPOSE: Effective stone disintegration by extracorporeal shockwave lithotripsy (ESWL) may depend on patient- and stone-related factors. We investigated predictors of disintegration failure in ESWL for a solitary ureteral calculus. METHODS: From July 2008 to May 2010, 203 patients who underwent ESWL for a solitary ureteral calculus were enrolled. Clinical and radiologic data were collected, and factors related to ESWL failure were analyzed. RESULTS: Fifty-two patients (25.6%) showed ESWL failure, with a mean follow-up of 41 days. Forty patients (19.7%) required retreatment, including 12 who underwent repeat ESWL and 28 who underwent curative ureteroscopy. Patients with ESWL failure had significantly higher body weight, body mass index (BMI), and buttock circumference (BC) than patients for whom ESWL was successful. Univariate analysis showed that stone burden (odds ratio [OR], 1.04; 95% confidence interval [CI], 1.03-1.06) and BC (OR, 1.06; 95% CI, 1.01-1.11) were predictors of ESWL failure, while BMI was a potential predictor with borderline significance (OR, 1.09; 95% CI, 0.99-1.20). Multivariate analysis showed that stone burden (OR, 1.04; 95% CI, 1.03-1.06) was a significant predictor for all patients. On stratifying patients according to the level of ureteral calculi, BC was found to be an independent predictor (OR, 1.35; 95% CI, 1.02-1.80) for ESWL failure for middle/lower ureteral calculi and BMI (OR, 1.47; 95% CI, 1.13-1.91) for upper ureteral calculi. CONCLUSION: Stone burden is the main predictor of ESWL failure for all patients with ureteral calculi. BC and BMI are independent predictors for ESWL failure for middle/lower and upper ureteral calculi, respectively.

ABSTRACT

OBJECTIVE: To investigate the correlation between prostatic calcification and lower urinary tract symptoms (LUTS) in a sample of middle-aged men receiving health checkups. METHODS: Subjects aged 40 years or older who voluntarily underwent transrectal prostate ultrasound (TRUS) and fulfilled International Prostate Symptoms Score (IPSS) as part of their medical checkup were enrolled in this study. The prostatic calcification grading and prostate volume (PV) were measured by TRUS. The medical history, demographics, and metabolic markers were also evaluated. Logistic regression was used to analyze the correlation between prostatic calcification and LUTS. RESULTS: A total of 604 men were enrolled as study subjects. The prostatic calcification grading was significantly associated with age and PV instead of metabolic markers. Compared to the nonprostatic calcification group, the moderate/marked prostatic calcification group had a significantly higher age-adjusted IPSS (8.69 vs 6.87, P <.01), quality of life (QOL) score (2.57 vs 2.17, P <.01), storage score (3.74 vs 3.06, P = .01), voiding score (4.95 vs 3.72, P <.01), and more maximum flow rate <15 mL/sec (40.4% vs 24.5%, P <.01). Prostatic calcification grading was positively correlated with age-adjusted IPSS, QOL, voiding, and storage scores (all P for trend <.05). Further multivariate analysis indicated that moderate/marked prostatic calcification was an independent risk factors for moderate to severe LUTS (odds ratio [OR] = 1.68, P = .02). CONCLUSION: Prostatic calcification worsened IPSS, QOL, storage, voiding symptoms, and maximum urine flow (Qmax) in middle-aged men receiving a health checkup. Moderate/marked prostatic calcification was an independent risk factor for moderate to severe LUTS.

ABSTRACT

The objective of this study is to evaluate the effects of solifenacin on double-J stent-related symptoms following uncomplicated ureterosocpic lithotripsy (URSL). A total of 70 patients who underwent double-J ureteral stent insertion following URSL were consecutively recruited and received solifenacin postoperatively. Another 70 age- and sex-matched subjects without solifenacin therapy were enrolled as a control group. The clinical data including stone and stent characteristics were collected. All subjects completed the brief-form Ureteral Symptom Score Questionnaire (Chinese-version) to assess the lower urinary tract symptoms, stent-related body pain and hematuria 2 weeks after operation. The severity of stent-related symptoms was compared between two groups. The mean age was 53.8 in solifenacin group and 53.4 years in the control group (p = 0.87). The stone characteristics, stent size, position and curl completeness were similar in both groups. Compared to the control group, solifenacin group had significantly lower total symptom score, urgency and urge incontinence scores. As for stent-related body pain, solifenacin group had significantly less flank, abdominal, urethral pain and hematuria scores (all p < 0.05). The solifenacin versus control group showed significant benefits in lower urinary tract symptoms, stent-related pain and hematuria in both genders (all p < 0.05). Four subjects encountered minor adverse events (5.7 %) and one had urinary retention (1.4 %) in solifenacin group. For patients undergoing URSL and double-J stent indwelling, postoperative solifenacin use was effective and well-tolerated for the treatment of lower urinary tract symptoms, stent-related body pain and hematuria irrespective of genders.

ABSTRACT

BACKGROUND/PURPOSE: Children with attention deficit hyperactivity disorder (ADHD) tend to be more vulnerable to various forms of voiding dysfunction and nocturnal enuresis (NE). We attempt to compare the clinical manifestations and attentional performance between ADHD children with NE and those without NE. METHODS: We consecutively enrolled children diagnosed with ADHD in child and adolescent psychiatric clinics. The questionnaires for evaluation of ADHD symptoms and voiding dysfunction symptoms were administered to all study participants. All participants also received the Test Battery for Attention Performance (TAP) for assessment of attentional function. RESULTS: A total of 53 children were enrolled in this study, comprising 47 boys and six girls. The prevalence rate of NE was 28.3%. Children in the NE group had statistically significant higher dysfunctional voiding symptom score (5.40 ± 3.66 vs.3.16 ± 2.74; p = 0.018) and two subscales of "When I wet myself, my underwear is soaked" (p < 0.001) and "I miss having a bowel movement every day" (p = 0.047). There were no significant differences with regard to all psychiatric evaluations between the NE and non-NE groups. In the TAP test, the NE group showed a significantly shorter reaction time in the domain of inhibitory control, working memory, and auditory sustained attention than the non-NE group. CONCLUSION: Children with ADHD have a high prevalence of NE. ADHD children with NE had a significantly higher dysfunctional voiding symptom score and shorter reaction time in most domains of the TAP test. Further study is needed to discern the impact of NE on the neuropsychological function of ADHD children.

ABSTRACT

OBJECTIVE: To investigate the impact of metabolic syndrome on lower urinary tract symptoms in a sample of middle-aged men receiving a health checkup. METHODS: Subjects aged 45 years or older who voluntarily underwent a medical checkup were enrolled. Participant demographics and health history were collected by a self-administered questionnaire. All participants were stratified into 2 groups by the presence of metabolic syndrome, as defined according to the updated National Cholesterol Education Program's Adult Treatment Panel III. Prostate volume and prostate-specific antigen levels were used for subgroup analysis. RESULTS: During January through December of 2010, 708 subjects with a mean age of 55.6 ± 9.72 years were enrolled into the study. Compared to the nonmetabolic syndrome group, the metabolic syndrome group had lower total international prostatic symptoms score (7.89 ± 6.63 vs 6.85 ± 6.52, P = .05) and lower severity of weak urinary stream (1.24 ± 1.60 vs 0.95 ± 1.50, P = .021). In the higher prostate volume group (prostate volume ≥ 30 mL), total international prostatic symptoms score, storage score, and urinary frequency, urgency and incomplete emptying were lower in men vs those without metabolic syndrome (all P < .05). The negative association between voiding score, severity of lower urinary tract symptoms, and metabolic syndrome became particularly pronounced as the number of metabolic syndrome factors increased (P for trend < .01). CONCLUSION: We confirmed that metabolic syndrome had favorable effects on lower urinary tract symptoms, including voiding and storage symptoms in healthy middle-aged men. This beneficial effect was most significant in men with enlarged prostate and/or high prostate specific antigen levels.

ABSTRACT

OBJECTIVE: To compare the efficacy and toxicity profiles of 3 intravesical regimens, including doxorubicin alone, bacillus Calmette-Guerin (BCG), and a cocktail regimen, in the prevention of bladder cancer recurrence. MATERIALS AND METHODS: Two hundred ninety patients with newly diagnosed non-muscle-invasive bladder cancer treated with transurethral resection (TUR) between March 1996 and December 2004 were analyzed retrospectively. Each cycle of the cocktail regimen contained 30 mg each of sequential weekly intravesical mitomycin-C (MMC), doxorubicin, and cisplatin (MDP). Two cycles of MDP were given within the first 6 weeks of TUR, followed by 1 cycle each at 3, 6, and 12 months, and every 6 months until 36 months after a negative cystoscopy. Doxorubicin and BCG alone was given at similar time points as the MDP and BCG protocols. RESULTS: There were no demographic differences among the 3 groups. The median follow-up duration was 50 months. Dropout rates due to intolerance and/or poor compliance with the BCG, doxorubicin, and MDP protocols were 22.5%, 16.8%, and 11.0%, respectively. The MDP and BCG groups had similar bladder recurrence rates (37.9% vs. 33.9% at 5 years, respectively; P = 0.69). The doxorubicin group had significantly more recurrences than the BCG or MDP groups (HR = 1.9 (vs. BCG; P = 0.02) and 1.8 (vs. MDP; P = 0.01)). MDP was associated with less major adverse events than BCG (5.8% vs. 15.0%, respectively; P = 0.02). CONCLUSIONS: Compared with maintenance BCG, the MDP group had a similar recurrence rate but less side effects. Large randomized study is warranted to further determine the benefit of MDP adjuvant intravesical therapy.

ABSTRACT

PURPOSE: We clarified correlations between symptoms of attention deficit disorder with hyperactivity and voiding dysfunction in children. MATERIALS AND METHODS: The study sample consisted of 92 boys and 38 girls 4 to 14 years old who presented at pediatric urology clinics with untreated lower urinary tract symptoms. Parents completed the Swanson, Nolan and Pelham-IV scale. Each subject with a combined score in the first 2 subscales (inattention, hyperactivity/impulsivity) at or above the 90th percentile was classified as having symptoms of attention deficit disorder with hyperactivity. All other cases were classified as nonattention deficit disorder. Voiding dysfunction symptoms were assessed by the Dysfunctional Voiding Symptom Scale. Sleep quality was assessed by the Pediatric Sleep Questionnaire. We then analyzed correlations between Dysfunctional Voiding Symptom Scale and symptoms of attention deficit disorder with hyperactivity. RESULTS: The group with symptoms of attention deficit disorder with hyperactivity had significantly higher scores on the Dysfunctional Voiding Symptom Scale overall and in the "cannot wait" subscale compared to the group without attention deficit disorder, as well as poorer sleep quality and lower voiding volumes. Overall Dysfunctional Voiding Symptom Scale scores were significantly correlated with overall Swanson, Nolan and Pelham-IV scale scores and also significantly correlated with each of the 3 Swanson, Nolan and Pelham-IV subscales (inattention, hyperactivity/impulsivity and oppositional defiant). Overall Dysfunctional Voiding Symptom Scale scores and scores on the "cannot wait" and "hurt when pee" subscales were significantly higher for males than for females. CONCLUSIONS: Boys with higher scores of attention deficit disorder with hyperactivity symptoms tend to have higher Dysfunctional Voiding Symptom Scale scores. Lower urinary tract symptoms were significantly correlated with overall Swanson, Nolan and Pelham-IV scores and significantly correlated with each of the 3 subscales. Evaluation of concomitant symptoms of attention deficit disorder with hyperactivity in children with lower urinary tract symptoms is an important clinical concern.
