Objective: To evaluate the relationship between pelvic organ prolapse in Korean women and joint hypermobility, which suggests a metabolic collagen fiber abnormality.
Study Design: Between March 1998 and March 2000, we investigated 55 patients with prolapse. The prevalence of joint hypermobility, by measuring finger extension angle, and the proportion of patients with joint hypermobility were measured in patients with pelvic organ prolapse and benign gynecologic patients (control group).
Results: In middle-aged women (40-59 years), the average finger extension angles were higher in the POP group than in the control group (50.04 +/- 9.70 degrees vs. 39.50 +/- 12.19 degrees, respectively; P < .05), but in older women there was no significant difference between the two groups (42.84 +/- 13.05 degrees vs. 43.00 +/- 13.34 degrees, respectively; P > .05).
Conclusion: The prevalence of joint hypermobility was higher in the POP group and with advanced POP stage (III, IV) than in the control group and early POP stage (I, II). Our results suggest that intrinsic connective tissue abnormality is related to the development of pelvic organ prolapse. Further study involving more patients with pelvic organ prolapse is warranted, and molecular studies to determine the genetic basis of pelvic organ prolapse are also required to further elucidate this abnormality.

Suppression of METTL3 expression attenuated matrix stiffness-induced vaginal fibroblast-to-myofibroblast differentiation and abnormal modulation of the extracellular matrix in pelvic organ prolapse.

Background: Fibrosis of the connective tissue in the vaginal wall predominates in pelvic organ prolapse (POP), which is characterized by excessive fibroblast-to-myofibroblast differentiation and abnormal deposition of the extracellular matrix (ECM). Our study aimed to investigate the effect of ECM stiffness on vaginal fibroblasts and to explore the role of methyltransferase 3 (METTL3) in the development of POP.
Methods: Polyacrylamide hydrogels were applied to create an ECM microenvironment with variable stiffness to evaluate the effects of ECM stiffness on the proliferation, differentiation, and expression of ECM components in vaginal fibroblasts.
The Role of Anterior Vaginal Prolapse in Co-Existent Underactive Overactive Bladder Syndrome-A Retrospective Cohort Study.

CUOB (co-existent underactive overactive bladder) syndrome is a clinical entity that embraces storage and emptying symptoms, not strictly correlated with urodynamic findings. We assessed the differences between patients diagnosed with CUOB with/without cystocele. The study group was allocated from 2000 women who underwent urodynamic studies between 2008 and 2016.

The aim of this study is to validate a uniform method for measuring perineal descent which can be used for different imaging methods, to establish cut-off values for this measurement, and to assess diagnostic test accuracy (DTA) of imaging techniques using these cut-off values. Secondly, the study aims to correlate perineal descent to symptoms, signs and imaging findings in women with obstructed defaecation syndrome (ODS) to assess its clinical relevance. Cross-sectional study of 131 women with symptoms of ODS.

The anterior vaginal wall is frequently affected by prolapse, which is frequently treated with anterior colporrhaphy. However, this repair has a high recurrence rate, and no standardized approach exists. Our study aimed to compare two suture techniques concerning postoperative outcomes.

: A prediction model for anatomical cystocele recurrence after native tissue repair was developed and internally validated in 2016. This model estimates a patients' individual risk of recurrence and can be used for counseling. Before implementation in urogynecological clinical practice, external validation is needed.
