Comparison of the overactive bladder symptom score and the overactive bladder symptom score derived from the bladder diaries

Prevalence of Pelvic Floor Disorders in Parous Women from the Tibet Autonomous Region: A Cross-Sectional Study

Purpose

Pelvic floor disorder (PFD) seriously affects the everyday life of women. This cross-sectional study aimed to evaluate the prevalence and risk factors for postpartum PFD in women living in the Tibet Autonomous Region (TAR).

Methods

Parous women who attended the outpatient gynaecology clinic at our hospital between June 2022 and August 2022 were screened in this study. The demographic and clinical data of these women were collected. Their pelvic floor functions were evaluated via a pelvic organ prolapse (POP) quantification examination, the Pelvic Floor Distress Inventory Questionnaire-20 (PFDI-20) and the Overactive Bladder Symptom Score (OABSS).

Results

A total of 201 women were included in this study, of whom 81.09% (163/201) were Tibetan. Twenty-seven women (13.43%) were diagnosed with POP stage ≥2 and 27 women (13.43%) with an OABSS score ≥3. The median PFDI-20 total score was 4.17 (range 0-43.75). Han women (n = 38) in the TAR had much lower PFDI-20 total scores, compared with Tibetan women (n = 163) (p < 0.05). The results of the multiple linear regression models showed that the PFDI-20 scores obtained from women living in the TAR were closely related to parity, history of heavy weight lifting, age, history of instrumental deliveries, ethnicity and number of caesarean sections.

Conclusion

Pelvic floor disorder is common among parous women living in the TAR. Ethnicity, parity, history of heavy weight lifting, age, history of instrumental deliveries and number of caesarean sections are the factors closely related to the PFDI-20 scores.

Prognostic Factors for Resolution Delay of Lower Urinary Tract Symptoms in Patients with Prostate Cancer after Low-Dose-Rate Brachytherapy

Urinary storage symptoms after low-dose-rate brachytherapy (LDR-BT) with iodine-125 have been noted to be less likely to improve to baseline compared to voiding symptoms. This study aimed to evaluate the chronological changes in the overactive bladder symptom score (OABSS) and the time-to-resolution of OABSS in patients undergoing LDR-BT. Patients with prostate cancer who underwent LDR-BT at Gifu University Hospital were enrolled. The OABSS was evaluated before and after LDR-BT. Patients were divided into the OABSS resolution and resolution delay groups, and the association between OABSS resolution delay and clinicopathological covariates was evaluated. In total, 237 patients were enrolled in this study, with a median follow-up of 88.3 months. The OABSS in both groups worsened at 3 months following operation and gradually recovered at 9 months; however, the OABSS in the resolution delay group tended to worsen again after that. In the multivariate analysis, preoperative OABSS and the change from baseline to maximal OABSS were associated with OABSS resolution. To our knowledge, this is the first study to evaluate the delayed resolution of OABSS after LDR-BT in patients with prostate cancer. A low baseline OABSS and significant changes in the OABSS from baseline were independent predictors of delayed OABSS resolution.

Feasibility and clinical implications of 3-day bladder diary derived classification of female storage lower urinary tract symptoms

Our aim was to assess the feasibility of a bladder diary (BD) classification as a surrogate for urodynamic studies in women with storage lower urinary tract symptoms. A total of 3823 women who underwent urodynamic studies were reviewed. Nearly the scores of Patient Perception of Bladder Condition, Indevus Urgency Severity Scale and Overactive Bladder Symptom Score decreased gradually from the overactive bladder (OAB) wet-BD, OAB dry-BD, hypersensitive bladder (HSB) -BD, nocturia-BD to normal-BD groups (all p < 0.001). In addition, there is a trend that the rates of bladder oversensitivity decreased gradually from the OAB wet-BD, OAB dry-BD, HSB-BD, nocturia-BD to normal-BD groups (chi-square test, p < 0.001). Moreover, almost the volumes of first desire to void, normal desire to void, strong desire to void, and urgency increased gradually from the OAB wet-BD, OAB dry-BD, HSB-BD, nocturia-BD to normal-BD groups (all p < 0.001). Thus, this BD classification is correlated significantly with symptom severity, the rate of bladder oversensitivity, and bladder capacity. Nonetheless, a combination of urodynamics, clinical history, and BD is still needed for a thorough diagnosis, but that BD provides an efficient diagnosis in a proportion of patients.

[Reproducibility of bladder diary in patients with multiple sclerosis]

INTRODUCTION

Multiple sclerosis (MS) is a neurological condition characterized by variable levels of symptoms. This variability could also affect bladder dysfunction and impact on the reproducibility or stability of bladder diary (BD). The aim of the study is to investigate the reproducibility and reliability of BD in MS, and then determine its linked factors.

METHODS

The MS patient provided a 21 days BD and they documented the time of every void. The main criterion was assessed by voiding frequency, represented by the coefficient of variation (CV=average/standard deviation), expressed as a percentage. Two groups were described: stable BD group (CV≤15 %) and instable BD group (CV>15 %). Secondary criteria were completion of BD (complete or not) and the difference of voiding frequency variation between weekend and week.

RESULTS

Thirty-one patients were included (mean age 51.06 years, SD 11.33) with 65 % of women. Mean CV is 23 % (SD 0.11). The mean completion of BD was 19.35 days (SD 3.99). 8 patients had a CV≤15 %. Stable group was older than instable group (P=0.03). There was no other difference between the 2 groups. There is a strong correlation between mean voiding frequency weekend and week (ρ=0.94, P<0.05). The longer duration of BD, the less reliability is notified.

CONCLUSION

BD is not a stable reproducible in MS population. Both lack of compliance or variability of LUTS in MS may explain the unreliability of BD. However, BD utility should be discussed in this population.

Quantitative analysis of genitourinary toxicity after iodine-125 brachytherapy for localized prostate cancer: Followup of the International Prostate Symptom Score and Overactive Bladder Symptom Score

PURPOSE

To analyze genitourinary toxicity by followup of the International Prostate Symptom Score (IPSS) and Overactive Bladder Symptom Score (OABSS) after prostate brachytherapy.

METHODS AND MATERIALS

Six hundred eighty patients were treated with iodine-125 brachytherapy for localized prostate cancer. IPSS, OABSS, and two categories of IPSS questions (storage symptom score [IPSS-S] and voiding symptom score [IPSS-V]) were evaluated.

RESULTS

The median followup was 54 months (range, 24-108). All scales showed rapid increases followed by gradual decreases. The median times to IPSS peak and resolution were 1 and 6 months, respectively. The resolution rates of IPSS, IPSS-S, IPSS-V, and OABSS at the last followup were 84.2%, 86.3%, 89.5%, and 83.0%, respectively. The difference between IPSS baseline and peak was greater for larger preimplant prostate volumes (≥25 mL, p = 0.004). The time to resolution was longer for higher biologic effective dose (BED) (≥210 Gy, p = 0.019 [IPSS]), in those with larger prostate volumes (≥25 mL, p = 0.025 [OABSS]), in younger patients (younger than 70 years, p = 0.043 [IPSS-S]), and in those with androgen deprivation therapy (ADT) use (p = 0.049 [IPSS-V]). Urge incontinence, included in the OABSS, was observed more commonly in older patients (75 years and older, p = 0.018), with ADT use (p < 0.001), and for higher BED (≥210 Gy, p = 0.006).

CONCLUSIONS

The IPSS and OABSS showed similar patterns of change. Urinary symptoms improved more rapidly in those with high baseline IPSS levels. The OABSS was useful for following urinary symptoms after prostate brachytherapy. Age, ADT use, preimplant prostate volume, and BED were significantly associated with urinary outcomes.
