The α1 adrenoceptor antagonist tamsulosin for the treatment of voiding symptoms improves nocturia and sleep quality in women.

PURPOSE: Nocturia is the main cause of disturbance of sleep maintenance and negatively impacts quality of life (QoL). We assessed the effects of the α1-adrenoceptor antagonist, tamsulosin, on nocturia and quality of sleep, for the treatment of lower urinary tract symptoms (LUTS) in women with a maximal flow rate (Qmax) less than 15 mL/sec. MATERIALS AND METHODS: From January 2008 to December 2009, women with LUTS [Qmax ≤ 15 mL/s, International Prostate Symptom Score (IPSS) ≥ 8] and nocturia (void/night ≥ 1) were selected for this study. Two hundred ninety six patients completed voiding diary, a questionnaire on the Medical Outcomes Study (MOS) sleep scale and underwent follow-up evaluation after 4 weeks of treatment (tamsulosin, 0.2 mg, once daily). Effectiveness was assessed by analysis of the IPSS, the bother score, the Qmax, and postvoid residual urine (PVR). RESULTS: The mean number of voids per night was 2.66 ± 1.3, and the total IPSS and bother scores were 15.2 ± 8.9 and 3.4 ± 1.2, respectively. Clinical parameters, including the IPSS, the bother score, the Qmax and the PVR, improved significantly from baseline after treatment (P < .05). The change in nocturia was -1.12 (P < .05). Concerning sleep quality, the sleep problem index showed a significant decrease. Among the items on the sleep subscale, sleep disturbance, somnolence, and sleep adequacy were significantly changed (P < .05). CONCLUSION: The α1-adrenoceptor antagonist tamsulosin significantly improved nocturia and sleep quality as well as LUTS in women with low Qmax.

Impact of nocturia on health-related quality of life and medical outcomes study sleep score in men.

PURPOSE: To evaluate the impact of nocturia on health-related quality of life and sleep in men. METHODS: From January 2008 to December 2008, 284 patients with lower urinary tract symptoms were selected for this study. The participants completed a series of questionnaires on health-related quality of life (the overactive bladder questionnaire, or OAB-q), the Medical Outcomes Study (MOS) sleep scale, and the frequency volume chart. RESULTS: The patient population had a mean age of 60.0±13.4 years (range, 40 to 79 years). The mean duration of symptoms was 28.8±34.6 months. The mean number of voiding episodes per night was measured as follows: 88 patients (31.0%) reported no nocturia, 60 patients (21.1%) reported 2>voids/night ≥1, 56 patients (19.7%) reported 3>voids/night ≥2, and 80 patients (28.2%) reported ≥3 voids/night. The mean number of nocturia episodes increased with age (P=0.001), and the number of nocturia episodes was significantly associated with the OAB-q symptom score (P=0.001) and symptom bother (P=0.001). Among the categories of the MOS sleep scale, sleep index I (P=0.020), sleep disturbance (P=0.010), adequacy of sleep (P=0.005), and somnolence (P=0.041) were significantly associated with an increased number of nocturia episodes. CONCLUSIONS: The number of nocturia episodes increased with age in men. Nocturia appeared to be associated with further negative effects on sleep quality, health-related quality of life, and symptom bother.

Use of the NMP22 BladderChek test in the diagnosis and follow-up of urothelial cancer: a cross-sectional study.

OBJECTIVES: To investigate the efficacy of the nuclear matrix protein (NMP) 22 BladderChek test (NMP22BC) in the detection and follow-up of urothelial carcinoma. MATERIAL AND METHODS: A total of 1021 patients who underwent the NMP22BC, cytology, and cystoscopy, were studied. We divided the patients into 2 groups: group I consisted of 597 patients who were being followed up for previous urothelial carcinoma, and group II consisted of 424 patients with hematuria. The sensitivity and specificity of the NMP22BC, cytology, and the combination (NMP22BC + cytology) were compared. RESULTS: Of the 1021 patients, 131 were diagnosed with urothelial cancer. The overall sensitivities for the NMP22BC, cytology, and the combination were 32.1%, 38.2%, and 52.7%, respectively. In group I, the sensitivity of the NMP22BC was lower than the sensitivity of cytology (22.58% vs 35.5%); there was no difference between the sensitivity of the NMP22BC and that of cytology in group II (40.58% vs 40.58%). For the combination, the sensitivity was greater than that of either test alone in both groups (46.77% and 57.97% in groups I and II, respectively). The sensitivity of the NMP22BC was greater than that of cytology (22.6% vs 13.2%) for low-grade bladder cancer. CONCLUSIONS: The NMP22BC has lower sensitivity than cytology. However, the sensitivity of NMP22BC in low-grade tumors was higher than that of cytology. Therefore, when the NMP22BC is combined with cytology, the sensitivity for detecting urothelial carcinoma is increased, which implies that this combination may be useful in the screening and follow-up of urothelial carcinoma.

Prostate calculi in cancer and BPH in a cohort of Korean men: Presence of calculi did not correlate with cancer risk.

Prostatic calculi are common and are associated with inflammation of the prostate. Recently, it has been suggested that this inflammation may be associated with prostate carcinogenesis. The aim of this study was to investigate the relationship between prostatic calculi and prostate cancer (PCa) in prostate biopsy specimens. We retrospectively analyzed 417 consecutive patients who underwent transrectal ultrasonography (TRUS) and prostate biopsies between January 2005 and January 2008. Based on the biopsy findings, patients were divided into benign prostatic hyperplasia and PCa groups. TRUS was used to detect prostatic calculi and to measure prostate volume. The correlations between PCa risk and age, serum total PSA levels, prostate volume, and prostatic calculi were analyzed. Patient age and PSA, as well as the frequency of prostatic calculi in the biopsy specimens, differed significantly between both the groups (P < 0.05). In the PCa group, the Gleason scores (GSs) were higher in patients with prostatic calculi than in patients without prostatic calculi (P = 0.023). Using multivariate logistic regression analysis, we found that patient age, serum total PSA and prostate volume were risk factors for PCa (P = 0.001), but that the presence of prostatic calculi was not associated with an increased risk of PCa (P = 0.13). In conclusion, although the presence of prostatic calculi was not shown to be a risk factor for PCa, prostatic calculi were more common in patients with PCa and were associated with a higher GS among these men.
