    ABSTRACT: We have recently developed the core lower urinary tract symptom score (CLSS) questionnaire to readily address 10 important lower urinary tract symptoms (LUTS). The aim of the present study was to evaluate the performance of the CLSS in women compared with the International Prostate Symptom Score (IPSS) and Overactive Bladder Symptom Score (OABSS). Three hundred and eighteen treatment-naïve consecutive female patients, including 48 controls, completed the three questionnaires. Quality of life (QOL) was determined as per the IPSS QOL Index. The clinical diagnoses were overactive bladder (n = 69), mixed incontinence (n = 42), stress incontinence (n = 17), pelvic organ prolapse (n = 56), interstitial cystitis (n = 31), bacterial cystitis (n = 16), underactive bladder (n = 16), and "other" (n = 23). Simple statistics and the relationship between symptom scores and poor QOL (QOL Index ≥ 4) were examined. All symptom scores were significantly increased in symptomatic women. The CLSS described the symptom profiles of patients with distinct conditions. The scores of corresponding symptoms on the three questionnaires were significantly correlated (r = 0.51-0.85; all P < 0.0001). Multivariate logistic regression modeling proved five CLSS symptoms (daytime frequency, nocturia, urgency incontinence, straining, and urethral pain) as independent predictors of poor QOL, with hazard ratios ranging from 2.0 to 4.2. The IPSS included only two (urgency and straining) significant symptoms. The IPSS alone does not fully evaluate female LUTS, with a possible negative impact on QOL. Using the CLSS questionnaire would enable a simple and comprehensive assessment of female LUTS.

    ABSTRACT: OBJECTIVE International Prostate Symptom Score (IPSS) has been commonly used to assess lower urinary tract symptoms (LUTS). We have recently developed Core Lower Urinary Tract Symptom Score (CLSS). The aim of this study is to compare IPSS and CLSS for assessing LUTS in men. PATIENTS AND METHODS Consecutive 515 men fulfilled IPSS and CLSS questionnaires. IPSS QOL Index was used as the QOL surrogate. The clinical diagnoses were BPH (n = 116), BPH with OAB wet (n = 80), prostate cancer (n = 128), prostatitis (n = 68), underactive bladder (n = 8), others (n = 72), and controls (e.g., occult blood) (n = 42). Simple statistics and predictability of poor QOL (QOL Index 4 or greater) were examined. RESULTS All symptom scores were significantly increased in symptomatic men compared with controls. Scores of corresponding symptoms of two questionnaires were significantly correlated (r = 0.58-0.85, all P < 0.0001). A multivariate regression model to predict poor QOL indicated nine symptoms (daytime frequency, nocturia, urgency, urgency incontinence, slow stream, straining, incomplete emptying, bladder pain and urethral pain) as independent factors. The hazard ratios for bladder pain (2.2) and urgency incontinence (2.0) were among the highest. All the nine symptoms are addressed in CLSS, while three symptoms (urgency incontinence, bladder, and urethral pain) are dismissed in IPSS. CONCLUSION CLSS questionnaire is more comprehensive than IPSS questionnaire for symptom assessment of men with various diseases/conditions, although both questionnaires can capture LUTS with possible negative impact on QOL.

    ABSTRACT: We will present an unusual case of endometrioid carcinoma that recurred in the upper urinary tract, showing an intraluminal spread, 11 years after hysterectomy for uterine corpus cancer. The case is a 72-year-old female who was referred to us for treatment of left ureteral cancer, at first. Nephroureterectomy was performed and histological examination showed endometrioid carcinoma similar to that resected 11 years earlier. A possible pathogenesis of this case will be discussed.

    ABSTRACT: A unique case of prostatic stromal sarcoma (PSS) that recurred in the pelvic cavity with massive high-grade prostatic intraepithelial neoplasia is described. A 52-year-old man who presented with urinary retention underwent a radical cystoprostatectomy. Tumour tissues of the prostate showed an admixture of hyperplastic glands and markedly cellular stroma of spindle cells arranged in a fascicular pattern, and the tumour was diagnosed as PSS. 66 months after the operation, CT scans revealed three recurrent tumours around the bilateral obturator and left fore iliopsoas. The recurrent tumours were biphasic neoplasms, as before, but the epithelial component had grown prominent and manifested overt atypia in a manner resembling high-grade prostatic intraepithelial neoplasia. Our findings suggest that not only the stromal component but also and the epithelial components of PSS may have malignant potential.

    ABSTRACT: To predict whether or not seminal vesicle invasion is present before radical prostatectomy, the relationships between clinical parameters and seminal vesicle invasion were analyzed. A review was conducted of 187 patients who had been clinically diagnosed with stages A(2), B(0), B(1), B(2) or C prostate cancer and who had undergone radical prostatectomy without neoadjuvant therapy. The parameters analyzed for potential predictors of seminal vesicle invasion before radical prostatectomy included age, clinical stage, serum prostate-specific antigen (PSA) level at biopsy, tumor differentiation of biopsy specimens and percentage of cancer positive cores by biopsy. For percentage of cancer positive cores by biopsy, 143 of 187 patients who underwent transrectal sextant biopsy or more than six transrectal ultrasound guided core biopsies were evaluated. These parameters were subjected to univariate and multivariate logistic regression analyses to identify predictors for seminal vesicle invasion. The median age was 66.8 years (range 51-77 years). Of 187 patients, 27 (14.4%) had seminal vesicle invasion confirmed pathologically. There were significant differences in all parameters except for age between patients with positive and negative seminal vesicle invasion on univariate analysis. Multivariate analysis revealed that serum PSA level, tumor differentiation of biopsy specimens and percentage of cancer positive cores were significant independent predictors of seminal vesicle invasion. The results showed serum PSA level, tumor differentiation of biopsy specimens and percentage of cancer positive cores by biopsy before radical prostatectomy may be useful predictors for seminal vesicle invasion.
