“…The change in LPA from rest to maximal Valsalva (ΔLPA) was calculated as vLPA minus rLPA, and the change in ARA from rest to maximal Valsalva (ΔARA) was calculated as vARA minus rARA. The LPA was de ned as the angle between the horizontal line at the inferior margin of the symphysis pubis and the line connecting the inferior margin of the symphysis pubis and the anorectal junction (20). The LPA was considered negative when the anorectal junction was located above the inferior margin of the symphysis pubis and positive when it was located below.…”

Background Confirming the patient's cervical position using transperineal ultrasound is not an easy task. This study aimed to employ transperineal ultrasound to measure the levator plate angle (LPA) and anorectal angle (ARA) in patients with varying degrees of uterine prolapse and to explore their efficacy in assessing uterine prolapse. Methods This prospective study consecutively enrolled 130 female patients who underwent examinations for lower urinary tract or pelvic floor dysfunction symptoms at the Second Affiliated Hospital of Fujian Medical University from August 2022 to December 2023. Participants were divided into three groups based on the Pelvic Organ Prolapse Quantification (POP-Q) system: POP-Q = 0 (n = 45), POP-Q = 1 (n = 45), and POP-Q ≥ 2 (n = 40). Transperineal ultrasound was used to measure the LPA and ARA at rest (rLPA and rARA) and during maximum Valsalva maneuver (vLPA and vARA). Changes in LPA and ARA from rest to maximal Valsalva (ΔLPA and ΔARA) were calculated. The differences in these ultrasound parameters among the three groups were compared. The area under the curve (AUC) was calculated to assess the diagnostic performance. Results With increasing severity of uterine prolapse, vLPA decreased progressively, while vARA and ΔARA initially decreased and then increased (P < 0.05). Compared with the POP-Q stage = 0 group, rLPA was reduced in the POP-Q stage ≥ 2 group, and ΔLPA was reduced in the POP-Q stage = 1 and POP-Q stage ≥ 2 groups (P < 0.05). The optimal cutoff values for diagnosing POP-Q stage ≥ 1 were 27.01° for rLPA, -2.29° for vLPA, and − 26.11° for ΔLPA, with corresponding AUCs of 0.65, 0.86, and 0.75. For diagnosing POP-Q stage ≥ 2, the optimal cutoff values were 24.11° for rLPA, -6.97° for vLPA, and − 34.57° for ΔLPA, with corresponding AUCs of 0.67, 0.80, and 0.69. DeLong's test indicated that vLPA had the highest efficacy in diagnosing both POP-Q stage ≥ 1 and POP-Q stage ≥ 2 (P < 0.05). Conclusion Transperineal ultrasound measurement of the LPA and ARA is a simple and effective method for assessing uterine prolapse.

Objective: To investigate the rate of postoperative urinary retention (POUR) and to identify factors associated with POUR of severe pelvic organ prolapse (POP). Methods: A retrospective chart review was conducted for 194 patients who were diagnosed with severe POP. Among them, 152 patients underwent total pelvic floor reconstruction and 42 patients underwent traditional vaginal hysterectomy and vaginal wall repair. POUR was defined as a need for the post-void residual urine volume was＞150mL who should be catheterization subsequent to the removal of the indwelling urethral catheter. Results: POUR was reported in 51 women (26.3%). The incidence of POUR was 28.3% of patients who underwent the total pelvic floor reconstruction. And was 19.0% after traditional vaginal hysterectomy and vaginal wall repair. Crude analysis revealed a significant association between the following variables and the risk of POUR: Aa, Ba, C by POP-Q exam, POP-Q staging, diabetes mellitus, Preoperative post-void residual volume (PVR) , bladder neck mobility, preoperative incontinence (P < 0.05) . POP-Q Staging (odds ratio, 4.79; 95% confidence interval, 1.025-22.383; P=0.046), PVR (odds ratio,1.054; 95% confidence interval, 1.03-1.079; P＜0.01), bladder neck mobility (odds ratio, 1.078; 95% confidence interval,1.021-1.138; P = 0.007) and complaint of incontinence (odds ratio, 2.686; 95% confidence interval,1.101-6.553; P = 0.03) were identified as the significant predictor of POUR In the logistic regression analysis. Conclusion: POP-Q staging, Preoperative post-void residual volume (PVR), bladder neck mobility and complaint of incontinence were significant predictors for POUR after severe pelvic organ prolapse surgery.
