Background: To study nocturia in patients with lower urinary tract symptoms (LUTS) suggestive of benign prostatic hyperplasia (BPH) after medical or placebo treatment., Methods: Patients with LUTS suggestive of BPH from several community clinics were included. Patients completed the International Prostate Symptom Score (I-PSS) questionnaire and a 3-day voiding diary. Urinalysis, prostate-specific antigen (PSA) measurement, and prostate ultrasonography were performed. Nocturnal polyuria (NP) was defined as a nocturnal urine fraction exceeding one third of the daily urine output in elderly men. A total of 148 outpatients were randomized to drug treatment (tamsulosin) or placebo treatment. After 8 weeks of treatment, they were re-evaluated using a 3-day voiding diary, PSA measurement, prostate volume (PV), I-PSS, etc. RESULTS: The average I-PSS score was 20.3, storage symptom score was 11.7, voiding symptom score was 8.6, quality of life (QoL) score was 3.7, PV was 40.4 ± 19.4 ml, and nocturnal urine volume (NUV) was 845.7 ± 339.0 ml. The mean frequency of nocturia was 2.3 ± 1.1 per day, and 94% of the patients had a nocturia frequency of more than two times per day. Of these patients, 76.5% had NP. A significant correlation was found between NUV and the amount of water intake at night and 4 h before sleep (r = 0.419,P = 0.002; r = 0.302,P = 0.031). Eighty patients were randomized to drug treatment (tamsulosin) and 68 patients were randomized to placebo treatment. The I-PSS score was 16.8 ± 4.9 to 19.3 ± 5.0 (p = 0.002), the storage symptom score was 10.3 ± 3.4 to 10.7 ± 3.4 (p = 0.007), and the voiding symptom score was 7.5 ± 2.4 to 8.6 ± 2.3 (p = 0.003). The frequency of daytime urination was 7.5 ± 2.6 to 8.1 ± 2.6 (p = 0.002), maximum urine volume (ml) was 372.8 ± 103.3 to 302.8 ± 119.3 (p = 0.007), and morning urine volume (ml) was 280.5 ± 111.7 to 259.5 ± 100.7 (p = 0.003). However, the frequency of nocturia score was 2.8 ± 0.7 to 3.0 ± 0.6 (p = 0.306) and the nocturnal urine volume (ml) was 800.7 ± 323.0 to 845.7 ± 303.5 (p = 0.056), which did not change significantly. There were significant differences between the NP and non-NP groups in the duration of LUTS, first voided urine volume, daytime urination frequency, and the amount of water intake at night and 4 h before sleep., Conclusions: Among the symptoms of LUTS, the improvement rates for nocturia were the lowest after medical treatment for BPH. The α-blockers did not improve nocturia, which was a common symptom accompanying LUTS suggestive of BPH. Our results showed that the prevalence of NP was 76.5% and that NP was significantly related to the amount of water intake during the evening and before sleep., Trial Registration: ISRCTN registry, Trial registration number (TRN): ISRCTN85509614 , Date of registration: 30/10/2018. This trial was registered retrospectively.

Objective: The main objective of the present study was to evaluate the presence of overactive bladder (OAB) syndrome, nocturia, urgency, and urge incontinence in patients with obstructive sleep apnea syndrome (OSAS), and measure bladder wall thickness (BWT) in these patients., Materials and Methods: The patient group was composed of 38 patients with OSAS. The control group was composed of 15 healthy individuals. All patients were evaluated using the Epworth Sleepiness Scale (ESS) and Overactive Bladder Symptom Score (OABSS). The bladder wall thickness was measured by transabdominal ultrasound (US). The presence of nocturia, urinary urgency, and urge incontinence were also evaluated., Results: The mean OABSS was significantly higher in the patient group compared with the control group (p=0.048). The minimum oxygen saturation (Min.SO2) of patients with urgency was found to be significantly lower (p=0.014). The time spent below 90% of oxygen saturation (SO2) was significantly longer in patients with urinary urgency (p=0.009). There was no difference in BWT measurements between the patient group and the control group. There was a significant relationship between BWT values and OABSS in patients with OSAS (p=0.002)., Conclusion: The results of the present study suggest that OSAS is associated with OAB syndrome. As a key symptom of OAB, urgency correlates with hypoxia in cases with OSAS. Although the present study did not observe any difference in BWT measurements between the patients and the control group, there was a correlation between BWT measurements and OABSS in patients with OSAS., Competing Interests: Conflict of interest: None declared., (Copyright® by the International Brazilian Journal of Urology.)

Objectives: To examine the prevalence, natural history, and clinical significance of high postvoid residual (PVR) volume in ambulatory older women., Design: Prospective cohort study., Setting: Group health plan in Washington state., Participants: Nine hundred eighty-seven ambulatory women aged 55 to 75., Measurements: PVR was measured using bladder ultrasonography at baseline, 1 year, and 2 years. Participants completed questionnaires about urinary symptoms and provided urine samples for microbiological evaluation., Results: Of the 987 participants, 79% had a PVR less than 50 mL, 10% of 50 to 99 mL, 6% of 100 to 199 mL, and 5% of 200 mL or greater at baseline. Of women with a PVR less than 50 mL, 66% reported at least one urinary symptom at baseline. Of women with a PVR of 200 mL or greater, 27% reported no significant symptoms at baseline. In adjusted analyses using data from all study visits, women with a PVR of 100 mL or greater were more likely to report urinating more than eight times during the day (odds ratio (OR)=1.42, 95% confidence interval (CI)=1.07-1.87), and women with a PVR of 200 mL or greater were more likely to report weekly urgency incontinence (OR=1.50, 95% CI=1.03-2.18) than those with a PVR less than 50 mL. High PVR was not associated with greater risk of stress incontinence, nocturnal frequency, or urinary tract infection in adjusted analyses. Forty-six percent of those with a PVR of 200 mL or greater and 63% of those with a PVR of 100 to 199 mL at baseline had a PVR less than 50 mL at 2 years., Conclusion: More than 10% of ambulatory older women may have a PVR of 100 mL or greater, which is associated with greater risk of some urinary symptoms, but many with high PVR are asymptomatic, and high PVR frequently resolves within 2 years. Symptom-guided management of urinary symptoms may be more appropriate than PVR-guided management in this population., (© 2011, Copyright the Authors.

Aims: To assess the relationship between mean bladder wall thickness and components of the overactive bladder (OAB syndrome)., Methods: Women attending urogynaecology clinic was categorized into overactive bladder syndrome, stress urinary incontinence (SUI), and mixed urinary continence (MUI) according to International Continence Society (ICS) definitions based on symptom history. Women completed a bladder diary, visual analog score (VAS) for urgency, and the mean bladder wall thickness (BWT) was determined. Comparison was made between the mean BWT and symptom history, daytime frequency, nocturia, VAS scores., Results: Three hundred seventy-nine women were recruited to the study with a mean age of 56 years (range: 24-92 years). The mean bladder wall thickness did not show any age-related difference. Of these women 138/379 (36%) reported overactive bladder symptoms (mean BWT = 5.6 mm) 75/379 (20%) gave a history of stress urinary incontinence (mean BWT = 4.7 mm), and 166/379 (44%) had mixed urinary incontinence (mean BWT = 5.4). Women with nocturia >1 had mean BWT 5.6 mm, with nocturia <1 a mean BWT 4.9 mm. Women with daytime frequency >7 had mean BWT 5.7 mm and those <7 had mean BWT 5.1 (P < 0.001). Women with a mean BWT of ≤5 mm had a mean VAS score lower than women with a BWT >5 mm (P < 0.001)., Conclusions: Mean BWT is associated with a symptom history of OAB and MUI, higher daytime and nightime frequency, and higher VAS scores., (© 2010 Wiley-Liss, Inc.)

Missing Intrauterine contraceptive devices can migrate to various regions intra-abdominally. Plain radiography usually confirms that the devise is still within the abdominal cavity, while other specific studies may define its relationship with the organ imaged. This is a case of a Migrated IUCD resulting in urinary symptoms.
