Anal canal coronal-sagittal ratio: a novel parameter for diagnosing pelvic floor injury in 2-dimensional transanal ultrasound.

Purpose: Pelvic floor injury diagnosis using 3-dimensional (3D) pelvic floor ultrasound or magnetic resonance imaging is unfeasible in many clinics. We assessed the efficacy of a novel diagnostic parameter, the anal canal coronal-sagittal (CS) ratio, for pelvic floor injury on 2D transanal ultrasound.

Methods: This retrospective study analyzed the data of 126 female patients who underwent 3D pelvic floor ultrasound (including 2D transanal ultrasound) at a pelvic floor center between August and December 2020.

Three-Dimensional Pelvic Floor Ultrasound Assessment of Pelvic Organ Prolapse: Minimal Levator Hiatus and Levator Ani Deficiency Score.

Purpose: The purpose of this study was to determine whether levator ani deficiency (LAD) scores and minimal levator hiatus (MLH) areas affect Pelvic Organ Prolapse Quantification (POP-Q) stage.

Methods: This study was a retrospective chart review of patients with pelvic organ prolapse (POP) at Seoul Songdo Hospital between August 2019 and August 2020. Three-dimensional (3D) pelvic floor ultrasound, preoperative anal manometry, and other physiological tests were performed in 78 patients with POP symptoms.

Levator plate descent angle in pelvic floor disorders.

Background: The levator plate descent angle (LPDA) quantifies the levator plate position with reference to the pubic bone and perineal body at rest. Unfortunately, research on this notable new parameter is lacking, but it is clear that levator ani deficiency (LAD) will undermine the fundamental role of the levator ani muscle (LAM) in organ support. The aim of this study was to establish the relationship between the LPDA and LAD in patients with pelvic floor disorders.

Predictors of postoperative urinary retention after semiclosed hemorrhoidectomy.

Purpose: This study was performed to analyze the predictors that might contribute to urinary retention following semiclosed hemorrhoidectomy under spinal anesthesia.

Methods: This retrospective study enrolled 2,176 consecutive patients with symptomatic grade III to IV hemorrhoids who underwent semiclosed hemorrhoidectomy between September 2018 and September 2019.

Results: Among the 2,176 patients, 1,878 (86.

Analysis of risk factors for delayed bleeding after semi-closed hemorrhoidectomy.

Purpose: The aim of this study was to determine the incidence of delayed post-hemorrhoidectomy bleeding (DPHB) after hemorrhoidectomy using a semi-closed procedure. We also investigated risk factors associated with DPHB.

Methods: This retrospective study enrolled a total of 1645 consecutive patients with symptomatic grade II to IV hemorrhoids who underwent a semi-closed procedure at the Seoul Songdo Hospital between September 2018 and May 2019.

Puborectalis Muscle Involvement on Magnetic Resonance Imaging in Complex Fistula: A New Perspective on Diagnosis and Treatment.

Purpose: According to recent studies, magnetic resonance imaging (MRI) assessment of complex fistulas provides a significant benefit compared to fistulography, computed tomography, and ultrasonography. The aim of this study was to describe the accuracy of MRI and the importance of identifying puborectalis muscle involvement on MRI in patients with complex fistula.

Methods: All patients who were clinically diagnosed with 'complex' or showed multiple fistula tracts underwent fistula MRI.

Comparison of 3-Dimensional Pelvic Floor Ultrasonography and Defecography for Assessment of Posterior Pelvic Floor Disorders.

Purpose: The aim of this study was to determine the accuracy of 3-dimensional (3D) pelvic floor ultrasonography and compare it with defecography in assessment of posterior pelvic disorders.

Methods: Eligible patients were consecutive women undergoing 3D pelvic floor ultrasonography at one hospital between August 2017 and February 2019. All 3D pelvic floor ultrasonography was performed by one examiner.
