Pelvic Organ Prolapse and Its Associated Factors Among Women Attending the Gynecology Outpatient Clinic at a Tertiary Hospital in Southwestern Uganda

Purpose

To determine the prevalence, clinical stage at presentation and factors associated with pelvic organ prolapse (POP) among women attending the gynecology outpatient clinic at Mbarara Regional Referral Hospital (MRRH), Uganda.

Methods

We conducted a cross-sectional study at the gynecology outpatient clinic of MRRH from September 2019 to January 2020. Women aged 18–90 years were systematically sampled and recruited into this study. An interviewer administered questionnaire was used to collect participants’ socio-demographic, obstetric, gynecological and medical factors. POP stage was obtained by using the pelvic organ prolapse-quantification system. Multivariable logistic regression analysis was done to determine factors associated with pelvic organ prolapse.

Results

Of 338 participants enrolled, the prevalence of POP was 27.5% [n = 93, 95% Cl: 23.0–32.5]. POP stages were stage I 11.8% (n = 11), stage II 63.4% (n = 59), stage III 16.1% (n = 15) and stage IV 8.9% (n = 8). Grand-multiparity (aOR 17.1, 95% CI: 1.1–66.6), birth weight more than 3.5kg (aOR 3.7, 95% CI: 1.1–12.6), perineal tears (aOR 6.5, 95% CI: 2.1–20.2), peasant farmer (aOR 6.9, 95% CI: 1.6–29.9) and duration of labour in the first delivery >24 hours (aOR 5.7, 95% CI: 1.2–29) were significantly associated with POP.

Conclusion

POP is common among women attending the gynecology clinic at MRRH with most of them presenting with stage II. There should be routine screening for POP to enable early identification and management especially in those who are grand multiparous, peasant farmers and have a history of perineal tears.

The association between different measures of pelvic floor muscle function and female pelvic organ prolapse

INTRODUCTION AND HYPOTHESIS

We aimed to compare palpatory and translabial ultrasound (TLUS) measurements of pelvic floor muscle (PFM) function with symptoms and signs of female pelvic organ prolapse (FPOP) to determine a possible association.

METHODS

We analysed data from 726 women with a mean age of 56 (SD 13.7, range 18-88) years, seen for symptoms of pelvic floor dysfunction between August 2011 and April 2013. The examination included a standardised interview and clinical assessment of FPOP with Pelvic Organ Prolapse Quantification (POP-Q) measurements, Modified Oxford Scale (MOS) grading and 4D TLUS.

RESULTS

Symptoms of prolapse were reported in 51.4% (373 out of 726) with a mean bother score of 5.8 (SD 2.91, range 0-10). A clinically significant POP (Incontinence Society [ICS]-POP-Q stage ≥ 2) in any compartment was diagnosed in 77.1%. Mean MOS was 2.4 (SD 1.1, range 0-5). Significant POP on TLUS was seen in 54.6% (389 out of 712). TLUS volumes at rest and on maximal PFM contraction were analysed on a desktop PC, to assess the degree of bladder neck (BN) cranioventral shift and levator antero-posterior (AP) diameter reduction, blinded against other data. Mean cranioventral BN shift was 7.11 (SD 4.36, range 0.32-25.32) mm and mean levator AP diameter reduction was 8.6 (SD 4.8, range 0.3-31.3) mm. MOS was strongly associated with subjective and objective POP (P ≤ 0.001), whereas this was not true for TLUS measurements of tissue displacement.

CONCLUSION

The MOS seems to be a more valid measure of PFM function than sonographically determined BN displacement or reduction of hiatal AP diameter observed on PFM contraction.

Prevalence of levator ani muscle injury and health-related quality of life in primiparous Chinese women after instrumental delivery

OBJECTIVES

Levator ani muscle (LAM) injury is common after first vaginal delivery, and a higher incidence is associated with instrumental delivery. This study was conducted to compare the incidence of LAM injury after forceps or ventouse extraction in primiparous Chinese women, and to study their subsequent health-related quality of life.

METHODS

This prospective observational study was conducted between 1 September 2011 and 31 May 2012 in a tertiary obstetric unit. All eligible primiparous women who had undergone instrumental delivery were recruited 1 to 3 days following delivery. The subjects completed the Pelvic Floor Distress Inventory questionnaire and Pelvic Floor Impact Questionnaire, and translabial ultrasound was performed 8 weeks' postpartum to determine whether the subjects had suffered LAM injury.

RESULTS

Among the 289 women who completed the study, 247 (85.5%) had ventouse extraction and 42 (14.5%) had forceps delivery. Subsequent translabial ultrasound identified a total of 58 women with LAM injury. The prevalence of LAM injury after ventouse extraction and forceps delivery was 16.6% (95% CI, 12.0-21.2%) (41/247) and 40.5% (95% CI, 25.6-55.4%) (17/42), respectively (P = 0.001). Forceps delivery was identified as a risk factor for LAM injury, with an odds ratio of 3.54. No statistically significant differences were observed between the quality of life in women who underwent ventouse extraction and those with forceps delivery or between the quality of life in women with a unilateral or bilateral LAM injury.

CONCLUSIONS

In our cohort of primiparous Chinese women, 20.1% (58/289) had LAM injury after instrumental delivery, and forceps delivery was identified as the only risk factor.

Perineal retraining improves conservative treatment for faecal incontinence: a multicentre randomized study

BACKGROUND

Anal incontinence is a frequent complaint that profoundly affects quality of life. Our aim was to determine whether perineal retraining gives additional benefits to standard medical treatment.

METHODS

Patients with anal incontinence and a Wexner score >4 were randomly assigned to standard conservative treatment (control) or perineal retraining, including biofeedback, in addition to standard treatments (biofeedback). Diaries, self-administered questionnaires and satisfaction scores quantified the benefits. Self-evaluated improvement was the primary outcome measure. A score ≥3 (in an improvement scale from -5 to +5) defined success.

RESULTS

Overall, 157 patients were included; 80 in the control group (75% females, mean age 60.1 ± 13.2 years) and 77 in the biofeedback group (79% females, mean age 61.9 ± 10.2 years). After a 4-month follow-up, the success rate was significantly higher in the biofeedback group (57% versus 37%; p<0.021). In the biofeedback group, daily stool frequency, leakage, and faecal urgency significantly decreased, and daily non-urgent perception of stool increased. Conversely, symptomatic scores and quality of life scales did not significantly differ between groups. In a multivariate model, the adjusted odds ratio showed that perineal retraining was significantly associated with a higher chance of self-rated improvement (adjusted Odd Ratio [95%CI]: 2.34 [1.14-4.80]; p=0.021).

CONCLUSIONS

Perineal retraining offers a moderate but significant benefit for patients suffering from anal incontinence.

Specific obstetrical risk factors for urinary versus anal incontinence 4 years after first delivery

AIM

Delivery can be complicated by urinary or anal incontinence (UI or AI). We hypothesized that the mechanisms of injury may differ for UI and AI. Hence, obstetrical risk factors may be specific for different types of incontinence.

DESIGN

Data on maternal characteristics were collected at first delivery. Data on incontinence were obtained by a questionnaire completed by 627 women 4 years after first delivery. UI was defined by "Do you have involuntary loss of urine" and AI by "Do you have involuntary loss of flatus or stool". A multinomial logistic regression analysis was conducted to assess risk factors for UI only, AI only, and UI+AI.

RESULTS

Twenty-two percent of women reported UI only, 6.5% AI only, and 6.5% both. Risk factors associated with UI only were age (at first delivery)≥ 30 (OR 2.27 [95% CI 1.47-3.49]), pre-existing UI (6.44 [2.19-19.0]) and pregnancy UI (3.64 [2.25-5.91]). Risk factors associated with AI only were length of the second active stage> 20minutes (2.86 [1.15-7.13]) and third degree perineal tear (20.9 [1.73-252]). Significant predictors of UI+AI were age ≥ 30 (2.65 [1.29-5.46]), no epidural (4.29 [1.65-11.1]), third degree perineal tear (20.0 [1.28-314]), and UI before pregnancy (32.9 [9.00-120]). Cesarean delivery was not significantly associated with UI, AI, or UI+AI, although for all three outcomes, the adjusted odds ratios were substantially less than one.

CONCLUSION

We found specific associations between obstetrical risk factors and urinary versus anal incontinence 4 years after first delivery. Our results are consistent with the hypothesis that the underlying mechanisms of injury differ for UI and AI.
