Significant Linkage Evidence for a Predisposition Gene for Pelvic Floor Disorders on Chromosome 9q21

Predisposition factors for pelvic floor disorders (PFDs), including pelvic organ prolapse (POP), stress urinary incontinence (SUI), urge urinary incontinence (UUI), and hernias, are not well understood. We assessed linkage evidence for PFDs in mostly sister pairs who received treatment for moderate-to-severe POP. We genotyped 70 affected women of European descent from 32 eligible families with at least two affected cases by using the Illumina 1 million single-nucleotide polymorphism (SNP) marker set. Parametric linkage analysis with general dominant and recessive models was performed by the Markov chain Monte Carlo linkage analysis method, MCLINK, and a set of SNPs was formed, from which those in high linkage disequilibrium were eliminated. Significant genome-wide evidence for linkage was identified on chromosome 9q21 with a HLOD score of 3.41 under a recessive model. Seventeen pedigrees (53%) had at least nominal evidence for linkage on a by-pedigree basis at this region. These results provide evidence for a predisposition gene for PFDs on chromosome 9q.     

Expression of matrix metalloproteinase-1 in uterosacral ligaments tissue of women with genital prolapse

Collagen metabolism is altered in the pelvic organ tissues of women with genital prolapse. The aim of this study was to compare collagen metabolism by measuring matrix metalloproteinase-1 (MMP-1) expression in uterosacral ligament tissues of postmenopausal women with and without genital prolapse. Uterosacral ligament tissues were obtained at the time of abdominal or vaginal surgery from twenty-four patients with pelvic organ prolapse (POP) and 21 women who underwent gynecologic surgery for benign indications. The tissue samples were analyzed by immunohistochemistry. There were no differences in age, BMI and parity between two groups. The patients with genital prolapse demonstrated significantly higher occurences of MMP-1 expression compared to controls. These findings indicate that increased MMP-1 expression in uterosacral ligaments is associated with genital prolapse. Our data are consistent with the theory that increased collagen breakdown may play an important role in the onset and development of pelvic organ prolapse (POP).

Immunohistochemical analysis of connective tissue in patients with pelvic organ prolapse

The uterosacral ligaments are an important part of the pelvic support system. The objective of this study was to compare the expression of collagen type I and collagen type III in the uterosacral ligament biopsies from women with and without pelvic organ prolapse (POP). The uterosacral ligament biopsies were obtained from women with POP (n = 29) and non-POP subjects (n = 35). Immunohistochemistry for collagen type I and collagen type III was performed on formalin-fixed and paraffin-embedded sections. The two groups were matched for age, body mass index, parity and postmenopausal status. The expression of collagen type I (p < 0.001) and collagen type III (p < 0.0001) differed between women with POP and non-POP subjects. There was decreased expression of collagen type I and increased expression of collagen type III in uterosacral ligaments of women with POP compared with non-POP subjects. This difference indicates a possible relationship between POP and the immunohistochemical expression of collagen type I and collagen type III in uterosacral ligaments.     

A biomechanical model to assess the contribution of pelvic musculature weakness to the development of stress urinary incontinence

A biomechanical model of the female pelvic support system was developed to explore the contribution of pelvic floor muscle defect to the development of stress urinary incontinence (SUI). From a pool of 135 patients, clinical data of 26 patients with pelvic muscular defect were used in modelling. The model was employed to estimate the parameters that describe the stiffness properties of the vaginal wall and ligament tissues for individual patients. The parameters were then implemented into the model to evaluate for each patient the impact of pelvic muscular defect on the vaginal apex support and the bladder neck support, a factor that relates to the onset of SUI. For the modelling analysis, the compromise of pelvic muscular support was demonstrated to contribute to vaginal apex prolapse and bladder neck prolapse, a condition commonly seen in SUI patients, while simulated conditions of restored muscular support were shown to help re-establish both vaginal apex and bladder neck supports. The findings illustrate the significance of pelvic muscle strength to vaginal support and urinary continence; therefore, the clinical recommendation of pelvic muscle strengthening, such as Kegel exercises, has been shown to be an effective treatment for patients with SUI symptoms.

The controversies regarding the role of estrogens in urogynecology

Estrogens are crucial for the proper functioning of genitourinary tract. Hypoestrogenism related to menopause could be linked to numerous disturbances of lower urinary tract. However, the results of most well designed clinical studies do not support use of estrogen or hormone replacement therapy for the treatment of genitourinary symptoms. According to evidence base medicine stress urinary incontinence, overactive bladder syndrome or pelvic organ prolapse are best treated by the surgery or non-hormonal drug therapy.     

Expression of estrogen receptors in the pelvic floor of pre- and post-menopausal women presenting pelvic organ prolapse

The precise role of estrogen in the pathogenesis of pelvic organ prolapse (POP) is still unclear, while the results concerning the effect of selective estrogen receptor modulators on pelvic organ prolapse are contradictory. Our aim was to test whether alteration in the expression of estrogen receptors in the pelvic floor of pre- and post-menopausal women is related to genital prolapse status. The mRNA levels of ERα and ERβ in 60 biopsy specimens were measured. Significantly higher expression of ERα and higher ERα/ERβ ratio were demonstrated in post-menopausal women compared to pre-menopausal women. Higher expression of ERα and higher ERα/ERβ ratio were detected in all studied groups with POP, thus it did not reach significance in the post-menopausal group. Pre-menopausal and post-menopausal women presenting pelvic organ prolapse had no difference in the ERα expression. Our preliminary study may indicate that pelvic organ prolapse is associated with higher expression of ERα/ERβ in the pelvic floor of both pre- and post-menopausal women; thus not reaching statistical significance in the post-menopausal women was probably due to the group's size. We believe that the inevitable changes in the estrogen receptor expression over women's different lifetimes may affect the risk of genital prolapse progression, and might contribute to the further search for appropriate selective estrogen receptor modulators as a treatment for women with pelvic organ prolapse.     

Epidemiology of pelvic floor disorders between urban and rural female inhabitants

The aim of this study was to investigate the prevalence of pelvic organ prolapse in urban and rural women and to identify possible related factors. They were 1749 participants; one thousand four hundred seventeen (81%) urban women and 332 rural residents (19%). The urban and rural women were congruently regarding to age, parity, using oral contraceptives and postmenopausal status. The urban women were more often obese (p < 0.01), estrogen replacement users (p < 0.001), smokers (p < 0.001), with mild (p < 0.001) and high (p < 0.001) education, and they were often divorced (p < 0.05) than rural women. Rural women were more often alcohol consumers (p < 0.001), with low level of education (p < 0.001) and more often married (p < 0.05) than rural examinees. There were no association between the presence of prolapse and: weight, menopausal status, oral contraceptives and estrogen replacement using, smoking, alcohol consuming and marital status. There were not observed differences in prevalence of prior hysterectomy, urinary incontinence, uroinfectio, sexual and bowel dysfunction between both groups. The prevalence of cystocele, rectocele and uterine prolapse were similar among urban and rural participants. In conclusion, a more complete picture of factors associated with genital prolapse would include in investigation, such as molecular and genetic ones.

Genetic covariation of pelvic organ and elbow mobility in twins and their sisters.

A range of environmental risk factors, with childbirth the most notable, have been associated with the development of pelvic organ prolapse and urinary incontinence. However, indications of genetic influence (positive family histories, ethnic differences) have prompted research into the heritability of measures of pelvic organ descent and joint mobility, which have also been associated with prolapse and incontinence. Genes appear to influence about half of the variation in these measures and, furthermore, the pelvic organ measures are associated with elbow hyperextension at a phenotypic level (r approximately .2). We examined these measures in young, nulligravid women to determine if their association is due to a common genetic source. Data were collected from 178 Caucasian female co-twins and non-twin sisters, 50 of whom returned to be retested, which allowed reliability to be estimated and unreliable variance to be isolated in the multivariate analyses. Structural equation modeling was used to estimate genetic associations between latent elbow and bladder mobility factors for which heritabilities were estimated to be 0.80 and 0.64 respectively. The association between these factors appeared to be mediated by common genes (genetic r = .48, non-shared environmental r = -.06), with genes influencing latent elbow mobility accounting for 14% of the variation in latent bladder mobility. We speculate that genes influencing connective tissue structure may underlie this association.     

盆底超声评价在妊娠妇女盆底结构、功能以及预后上的价值

为探究盆底超声检查评估分析不同的分娩方式对女性晚期妊娠和产后盆底结构、功能及预后效果的影响,本研究选取收治的100例顺利生产的孕妇作为本实验研究对象,根据分娩方式的不同将其分为自然分娩组与剖宫产组,各组50例。在两组孕妇妊娠晚期和产后分别通过盆底超声检测盆底结构和功能(膀胱旋转角,尿道膀胱后角,肛提肌裂孔面积和肛提肌裂孔周长);以及在产后第6~8周和盆底康复治疗后进行压力性尿失禁发生率调查问卷表填写及护垫实验。研究发现,阴道自然分娩比选择性剖宫产对妊娠晚期和产后孕妇盆底结构和功能造成的损伤更为显著;盆底损伤较严重的孕妇压力性尿失禁程度同样较严重;而盆底康复治疗成功的压力性尿失禁患者,盆底超声检测发现孕妇产后盆底结构和功能得到有效改善。本研究结果说明,盆底超声评价在检测不同分娩方式对妊娠晚期和产后孕妇的盆底结构、功能及预后存在一定的预测和预防作用。
