OBJECTIVETo explore the value of dynamic three-dimensional ultrasound in detecting the levator ani muscle fissures morphological changes of female pelvic floor relaxation syndrome after biofeedback and acupuncture treatments.
METHODSForty female constipation patients with pelvic floor relaxation syndrome were screened from the Constipation Designed Disease Clinic in our hospital between October 2011 and September 2012. Cleveland Constipation Score (CCS) scale was used. Anteroposterior and transverse diameters of the levator ani muscle fissures were measured by dynamic three-dimensional ultrasound in Valsalva maneuver. After a course (10 days) of biofeedback and acupuncture treatments, CCS scale was filled, and dynamic three-dimensional ultrasound was performed in Valsalva maneuver as well. Associated data before and after treatment were compared.
RESULTSTwenty-five patients completed the trial. As compared to pre-treatment, the longitudinal axes of levator ani muscle fissure [(4.89±0.89) cm vs. (5.13±0.82) cm, P<0.01], the horizontal axes of the levator ani muscle fissure [(4.62±0.75) cm vs. (4.86±0.74) cm, P<0.01], and the area of the levator ani muscle fissure [(18.16±6.42) cm(2) vs. (19.92±6.33) cm(2), P<0.01] decreased significantly after treatment, while CCS scale (9.52±2.50 vs. 15.80±3.42, P<0.01) declined significantly as well.
CONCLUSIONSThe dynamic three-dimensional ultrasound is an effective, simple and non-invasive method for the determination of levator ani muscle fissure in female patients with pelvic floor relaxation syndrome.

Objective To observe the patients after transvaginal mesh(TVM)implantation surgery by using transperineal ultrasound(TPUS),compare the diagnosis of pelvic organ prolapse(POP)by TPUS and clinical examination[according to the Pelvic Organ Prolapse Quantification(POP-Q)system published by the International Continence Society],and to explore the role of ultrasound in postoperative evaluation as well as the high-risk factors of post-surgery POP recurrence. Methods This is a retrospective study based on the POP-Q records and TPUS data sets of patients within 6 months after TVM surgery during September 2013 and November 2019.The diagnostic results of TPUS and POP-Q were compared.The incidences of hiatal ballooning and levator avulsion were separately compared between the TPUS group and the control group. Results A total of 147 patients were enrolled.The Kappa values between TPUS and POP-Q in the diagnosis of anterior and posterior compartment POP were 0.268(

OBJECTIVETo explore the feasibility of dynamic three-dimensional ultrasound measurement in the diagnosis of pelvic floor dyssynergia(PFD).
METHODSThirty female patients with PFD received dynamic three-dimensional ultrasound. The differences in angle α measured by transperineal three-dimensional ultrasound, and angle β, angle γ, and H line as measured by transanorectal three-dimensional ultrasound were compared between resting state and Valsalva maneuver. In addition, the detective rate of PFD by different parameters was analyzed.
RESULTSIn 30 patients, rectocele was found in 13 cases(43.3%), rectal internal mucous intussusception in 14 cases(46.7%), uterine prolapse in 11 cases(36.7%), and bladder prolapse in 1 case(3.3%). Compared with the resting state, α, β and H decreased obviously, but γ increased apparently in Valsalva maneuver, and differences of these parameters were statistically significant(all P<0.01). Detective rates of PFD for parameters of α, β, γ and H were 93.3%(28/30), 96.7%(29/30), 96.7%(29/30) and 86.7%(26/30), respectively.
CONCLUSIONMeasurements of α, β, γ and H can provide feasible indicators for clinical diagnosis of PFD.

The dimension of the levator hiatus is a possible predictor of pelvic organ prolapse (POP). This retrospective study investigated 360 women who went to urogynecological clinic for pelvic floor discomfort. Levator hiatus dimensions were obtained by three-dimensional transperineal ultrasound and results were compared between women with and without significantly objective prolapse (International Continence Society POP quantification, grade 2 or higher). Receiver operating characteristic (ROC) curve analyses were performed to determine valid screening index for detecting abnormal levator hiatus distensibility. Women with significantly objective prolapse had significantly higher levator hiatus dimensions than those without (all P < 0.001). ROC curve analyses confirmed that hiatal area (HA) of 19.5 cm during Valsalva maneuver can be used as single-screening index for abnormal levator hiatus distensibility with sensitivity of 0.80 and specificity of 0.70. In this study, we used a two-step method and achieved higher sensibility (0.80 vs. 0.87) without reducing specificity (0.70 vs. 0.71) compared with a single-screening index method. As a result, we suggest that HA ⩾ 19.5 cm during Valsalva maneuver is an indicator of abnormal levator hiatus distensibility in Chinese women and that the two-step method has higher sensitivity in detecting abnormal distensibility.

OBJECTIVETo evaluate the clinical value of simultaneously combined pelvic floor dynamic MRI and pelvic organography in diagnosing female pelvic floor disorders and search for the best imaging model for diagnosing pelvic floor disorders.
METHODSThirty women with pelvic floor disorders received pelvic floor dynamic MRI and simultaneously combined pelvic organography including cystourethrography, peritoneography, vaginography and defecography. Clinical diagnostic value was compared between this two methods.
RESULTSThe diagnostic accuracy of pelvic floor dynamic MRI and simultaneously combined pelvic organograph for cystocele,anorectal junction abnormal descent, pelvic floor hernia,uterocervical prolapse was 100%, 95.2 %, 86.7%, 85.7% respectively. Rectocele and prolapse of rectal were diagnosed by pelvic organograph in 12 and 28 cases respectively, while only 6 and 0 cases were diagnosed by pelvic floor dynamic MRI respectively. The mean examining time of pelvic floor dynamic MRI and simultaneously combined pelvic organography was (16 +/- 3)min, (34 +/- 9)min respectively (P< 0.01).
CONCLUSIONPelvic floor dynamic MRI combined with defecography is the best imaging model for diagnosing pelvic floor disorders.

This paper is to establish a three-dimensional finite element model (3D-FEM) of pelvic floor levator ani muscles in an old healthy women. We acquired the image data of the pelvic bones and pelvic floor muscles from CT and MRI scanning in a non-pregnant old healthy female volunteers. The 3-D reconstruction and mesh optimization of the whole pelvic bones and muscles with application of image processing software Mimics12.0 and Geomagic9.0 were obtained. Then we built the 3D-FEM of the musculoskeletal system of the pelvic bones and levator ani muscles with Ansys11.0 software. We obtained an accurate 3D-FEM of pelvic bones and levator ani muscles in the older healthy woman. The results showed that it was reliable to build 3D-FEM with CT and MRI scanning data and this model could vividly reflect the huge space anatomy of the real pelvic floor levator ani muscles. It avoids the defects to gain the model from the body of anatomical specimens in the past. The image data of model are closer to vivisection, and the model is more conducive to the latter finite element analysis.
