Effect of additional acupuncture to pelvic floor exercise on urinary incontinence: A randomized controlled trial.

AIMS: To investigate the additional benefit of acupuncture to pelvic floor exercise (PFE) on the improvement of urinary incontinence (UI) and quality of life (QoL) in women. METHODS: This was a single-blinded randomized controlled trial in a tertiary university hospital. Women with UI in various severity and types were randomized to receive either a weekly course of acupuncture with PFE or PFE alone for 6 weeks and then followed up for 24 weeks in every 6 weeks. Investigators were blinded to group allocation in pre- and postintervention assessments. Primary outcome was subjective changes of UI symptoms at 24 weeks. Secondary outcomes were episodes and severity of UI from bladder diary, severity by Visual Analogue Scale, and QoL scores by validated Chinese short-form of Urogenital Distress Inventory (UDI-6) and Incontinence Impact Questionnaire (IIQ-7). RESULTS: One hundred seventy-nine women were screened while 137 were randomized. Significant subjective improvement in UI symptoms was demonstrated at all follow-up, latest at 24 weeks (odds ratio [OR]: 2.29, 95% confidence Interval [CI]: 1.02-5.12, respectively), with reduced episodes and severity of UI after (p < 0.05), and a trend of improvement in IIQ-7 score (p = 0.05). No major adverse events occurred. History of 2 years or longer duration of UI symptoms was associated with lower effectiveness of acupuncture (OR: 0.08, 95% CI: 0.01-0.68).

An observational follow-up study on pelvic floor disorders to 3-5 years after delivery.

INTRODUCTION AND HYPOTHESIS: This study aimed to determine the prevalence of urinary incontinence (UI), fecal incontinence (FI), and pelvic organ prolapse (POP) 3-5 years after the first pregnancy and their associated risk factors. METHODS: We assessed 506 women using the Pelvic Floor Distress Inventory (PFDI) and the Pelvic Floor Impact Questionnaire (PFIQ). Maternal characteristics and obstetric data were analyzed using descriptive analysis, independent sample t test, chi-squared test, and logistic regression. RESULTS: The prevalence of UI, FI, and POP, respectively, at a mean of 43 months after first delivery was 40.8, 6.6, and 10.2% following vaginal delivery (VD) and 22.7, 4.5, and 4.5% following cesarean section (CS). Stress urinary incontinence (SUI) was reported by more women following VD than CS (38.7 vs 22.4%, P = 0.010). Compared with 8 weeks' postpartum, more women reported SUI at this later follow-up visit (40.1 vs 19.5%, P < 0.001), but fewer reported FI. More women who had an instrumental delivery reported symptoms of POP compared with those who had a normal VD. Higher body weight and weight gain from first trimester were risk factors of SUI [odds ratio (OR) 1.03] and urge urinary incontinence (UUI) (OR 1.18), respectively. Women who delivered vaginally had higher PFDI subscales scores. CONCLUSIONS: VD increased UI risk. Higher body weight and weight gain from first trimester were risk factors for SUI and UUI, respectively. More women reported symptoms of POP following an instrumental delivery than those who had a normal VD.

Responsiveness of the Pelvic Floor Distress Inventory and Pelvic Floor Impact Questionnaire in women undergoing treatment for pelvic floor disorders.

INTRODUCTION AND HYPOTHESIS: This study evaluated the responsiveness and minimal important differences (MID) of the Chinese Pelvic Floor Distress Inventory (PFDI) and Pelvic Floor Impact Questionnaire (PFIQ) in women undergoing urodynamic stress incontinence (USI) and/or pelvic organ prolapse (POP) treatment. METHODS: One hundred and fifty-six women were assessed using the PFDI and PFIQ before and after they received continence surgery and or pelvic floor repair (PFR) surgery, or vaginal pessary. Symptom severity was recorded using a visual analog scale (VAS) before and after treatment as was rating of their satisfaction with the treatment they received. Responsiveness of the PFDI and PFIQ were evaluated by effect sizes, standardized response mean, paired samples t test or Wilcoxon Signed Rank Test. MID in the PFDI and PFIQ for different treatments were determined by satisfaction rating, change in VAS scoring, and distribution-based methods. RESULTS: There were significant improvements in the respective subscales of PFDI and PFIQ, demonstrating moderate to great responsiveness after different treatments. The estimation of MID for the Urinary Distress Inventory (UDI) was -30 to -14 and the Urinary Impact Questionnaire (UIQ) was -28 to -14 for women who underwent continence surgery. The MID for the Pelvic Organ Prolapse Distress Inventory (POPDI) was -44 to -21, the Pelvic Organ Prolapse Impact Questionnaire (POPIQ) -40 to -27, the UDI -22 to -16, the UIQ -37 to -31, the Colo-Rectal-Anal Distress Inventory (CRADI) -37 to -14, and the Colo-Rectal-Anal Impact Questionnaire (CRAIQ) -34 to -6 for women who underwent PFR surgery; and estimation of MID for the POPDI was -16, the POPIQ -29, the UDI -28, the UIQ -17, the CRADI -25, and the CRAIQ -31 for women who received a vaginal pessary. The MID of the respective subscales were supported by the distribution-based methods. CONCLUSIONS: The Chinese PFDI and PFIQ instruments are responsive to change in women undergoing continence surgery, PFR surgery or vaginal pessary for USI or POP.

Symptoms, quality of life, and factors affecting women's treatment decisions regarding pelvic organ prolapse.

INTRODUCTION AND HYPOTHESIS: We performed an investigation of symptoms, quality of life (QOL), and factors affecting women's treatment choice of pelvic organ prolapse (POP). METHODS: Three hundred and eight women presenting with POP were assessed by Pelvic Floor Distress Inventory (PFDI), Pelvic Floor Impact Questionnaire (PFIQ), Short Form-36 (SF-36), Pelvic Organ Prolapse Quantification (POP-Q) system, and urodynamic studies. Treatment was arranged according to each woman's preference after counseling. Factors affecting treatment choice were evaluated. Descriptive statistics, chi-square or Fisher exact test, analysis of variance (ANOVA) test, and logistic regression analysis were used. RESULTS: Patients had high prevalence of urinary, prolapse, and bowel symptoms. Their QOL was impaired, with Urinary Impact Questionnaire (UIQ) higher than the Pelvic Organ Prolapse Impact Questionnaire (POPIQ) score and lower SF-36 score compared with the population norm. Logistic regression analysis indicated that complication from vaginal pessary, urodynamic stress incontinence (USI), stage of prolapse, and Pelvic Organ Prolapse Distress Inventory (POPDI) scoring were factors for choosing surgical treatment. CONCLUSIONS: Women with POP had great symptomatic distress and impaired QOL. Complication from vaginal pessary, USI, stage of prolapse, and POPDI scores were factors increasing the likelihood of the patient choosing surgical treatment.
