OBJECTIVETo analyze the parameters of urodynamic tests for patients with type-III B prostatitis and evaluate the significance of the results of urodynamic tests in the choice of therapies for this disease.
METHODSUrodynamic tests were performed for 87 type-III B prostatitis patients aged 22-45 (30.7 ± 8.5) years, who had moderate or severe lower urinary tract symptoms (LUTS) and failed to respond to routine therapy. Different treatments were administered according to the results of urodynamic tests followed by observation of the therapeutic effects.
RESULTSUrodynamic abnormalities were found in 70 of the 87 patients, bladder outlet obstruction in 28 (32.2%), detrusor overactivity in 25 (28.7%), bladder hyperesthesia in 18 (20.7%), low compliance in 10 (11.5%), detrusor-external urethral sphincter dyssynergia in 1 (1.1%), and impaired detrusor contractile function in 1 (1.1%). Treatments achieved obvious effectiveness in 26 cases (29.9%), effectiveness in 51 (58.6%), and no effectiveness in 10 (11.5%).
CONCLUSIONUrodynamic tests contribute significantly to the choice of therapies for type-III B prostatitis patients with moderate or severe LUTS.

We aimed to develop and validate a clinical nomogram predicting bladder outlet obstruction (BOO) solely using routine clinical parameters in men with refractory nonneurogenic lower urinary tract symptoms (LUTS). A total of 750 eligible patients ≥50 years of age who had previously not responded (International Prostate Symptom Score [IPSS] improvement <4 points) to at least three different kinds of LUTS medications (including a-blocker) for the last 6 months were evaluated as subcohorts for nomogram development (n = 570) and for split-sample validation (n = 180). BOO was defined as Abrams-Griffiths number ≥40, or 20-39.9 with a slope of linear passive urethral resistance ratio >2 cmH2O ml-1 s-1. A stepwise multivariable logistic regression analysis was conducted to determine the predictors of BOO, and b-coefficients of the final model were selected to create a clinical nomogram. The final multivariable logistic regression model showed that age, IPSS, maximum urinary flow rate, postvoid residual volume, total prostate volume, and transitional zone index were significant for predicting BOO; these candidates were used to develop the final nomogram. The discrimination performance of the nomogram was 88.3% (95% CI: 82.7%-93.0%, P < 0.001), and the nomogram was reasonably well-fitted to the ideal line of the calibration plot. Independent split-sample validation revealed 80.9% (95% CI: 75.5%-84.4%, P < 0.001) accuracy. The proposed BOO nomogram based solely on routine clinical parameters was accurate and validated properly. This nomogram may be useful in determining further treatment, primarily focused on prostatic surgery for BOO, without impeding the detection of possible BOO in men with LUTS that is refractory to empirical medications.

OBJECTIVETo investigate the incidence of erectile dysfunction (ED) in men with lower urinary tract symptoms (LUTS) and the correlation between LUTS and ED.
METHODSWe enrolled 1 000 men aged 40 - 80 years with regular sex partners, evaluated their erectile function using IIEF-5, and investigated LUTS among them by International Prostate Symptom Score (IPSS). We studied the relationship between ED and LUTS by univariate conditional Logistic regression analysis.
RESULTSLUTS were found in 42.81% of the men investigated (426/995), and ED in 76.18% of the subjects (758/995) and 82.16% of those with LUTS (350/426). Logistic regression analysis revealed a significant relation of ED with aging and LUTS (P < 0.01).
CONCLUSIONThe The incidence of ED is high in men with LUTS and increases with aging and the severity of LUTS.

This study aimed to investigate perceived ejaculatory function/satisfaction before treatment for lower urinary tract symptoms (LUTS)/benign prostatic hyperplasia (BPH) and to identify associations between specific categories of ejaculatory dysfunctions (EjDs) and LUTS. A total of 1574 treatment-naïve men with LUTS/BPH were included in this study. All patients underwent routine evaluation for LUTS/BPH including the International Index of Erectile Function and a 5-item questionnaire developed to assess ejaculatory volume/force/pain/satisfaction/latency time. Patients who had sexual intercourse over the past 4 weeks were classified as sexually active group. A total of 783 patients were categorized as sexually active group. Decreased ejaculatory volume and force were reported by 53.4% and 55.7% of 783 sexually active men, respectively. There was a strong correlation between ejaculatory volume and force. Ejaculatory pain/discomfort, premature ejaculation (PE), and delayed ejaculation (DE) were reported in 41.0%, 16.3%, and 41.4% of the patients, respectively. Over 40.0% of men without decreased ejaculation volume/force were satisfied with ejaculatory function, whereas approximately 6.0% of men with decreased volume/force were satisfied with ejaculatory function. About 30.0% of men with decreased volume/force had orgasmic dysfunction, while approximately 10.0% of men without decreased volume/force did. Decreased ejaculatory volume or force was associated with LUTS severity after adjusting for other influential factors including testosterone level, erectile function, and prostate size on ultrasonography, but PE or DE or ejaculatory pain/discomfort was not. In conclusion, a considerable portion of men with LUTS/BPH appear to have a variety of EjDs. Ejaculatory volume/force and satisfaction/orgasm do not always appear to be concordant. Ejaculatory volume or force is independently associated with LUTS severity, whereas PE or DE or ejaculatory pain/discomfort is not.

Ketamine is a short-acting anaesthetic agent that has gained popularity as a 'club drug' due to its hallucinogenic effects. Substance abuse should be considered in young adult patients who present with severe debilitating symptoms such as lower urinary tract symptoms, even though the use of controlled substances is rare in Singapore. Although the natural history of disease varies from person to person, a relationship between symptom severity and frequency/dosage of abuse has been established. It is important to be aware of this condition and have a high degree of clinical suspicion to enable early diagnosis and immediate initiation of multidisciplinary and holistic treatment. A delayed diagnosis can lead to irreversible pathological changes and increased morbidity among ketamine abusers.

PURPOSE: There is no reported evidence for an anthropometric index that might link obesity to men's sexual health. We evaluated the ability of an anthropometric index and the symptom scores of five widely used questionnaires to detect men's health problems. We determined the predictive abilities of two obesity indexes and other clinical parameters for screening for lower urinary tract symptoms and sexual dysfunction in middle-aged men. MATERIALS AND METHODS: A total of 1,910 middle-aged men were included in the study. Participants underwent a detailed clinical evaluation that included recording the symptom scores of five widely used questionnaires. The participants' body mass index and waist-to-hip ratio were determined. Serum prostate-specific antigen, urinalysis, testosterone, estimated glomerular filtration rate, evaluation of metabolic syndrome, and transrectal ultrasonography were assessed. RESULTS: By use of logistic regression analysis, age and total prostate volume were independent predictors of lower urinary tract symptoms. Metabolic syndrome was the only significant negative predictive factor for chronic prostatitis symptoms. Age and metabolic syndrome were independent predictive factors for erectile dysfunction. Waist-to-hip ratio had a statistically significant value for predicting erectile dysfunction. CONCLUSIONS: Our data showed that total prostate volume is a significant predictor of lower urinary tract symptoms, and central obesity has predictive ability for erectile dysfunction. Metabolic syndrome was the only significant negative predictive factor for chronic prostatitis-like symptoms. The management of correctable factors such as waist-to-hip ratio and metabolic syndrome may be considered preventive modalities against the development of men's health problems.
