transperineal ultrasonography

BACKGROUND: Transperineal ultrasound (TPUS) has become an increasingly popular tool in obstetrics due to its objective, non-invasive, and real-time imaging capabilities. AIM: This review aims to describe the basic approaches, current utilization, and potential future applications of TPUS. MATERIALS & METHOD: A comprehensive literature review on TPUS was conducted. In addition, discussions at academic meetings and congress focused on TPUS were also considered...

OBJECTIVE: To assess changes in diagnosis prostate cancer (PCa) grade, biopsy and treatment approach over a decade (2011-2020) at a population level within a clinical quality cancer registry. PATIENTS AND METHODS: Patients diagnosed by prostate biopsy between 2011 and 2020 were retrieved from the Victorian Prostate Cancer Outcomes Registry, a prospective, state-wide clinical quality registry in Australia. Distributions of each grade group (GG) proportion over time were modelled with restricted cubic splines, separately by biopsy technique, age group and subsequent treatment method...

BACKGROUND AND AIMS: Transabdominal ultrasonography (TAUS) appears comparable to colonoscopy for evaluating ulcerative colitis (UC) activity, but it has low accuracy in rectal evaluation. In this study, the accuracy of transperineal ultrasonography (TPUS) for evaluating rectal activity was compared to that of colonoscopy in pediatric UC cases. METHODS: Fecal calprotectin (FCP) values and TPUS and colonoscopic findings were compared prospectively in pediatric UC cases...

Although the fetal head position has traditionally been evaluated by digital examination (DE), it has a failure rate ranging between 20 and 70%; hence, intrapartum transabdominal ultrasonography (TUS) has become relevant. We aimed to evaluate the utility of the TUS to identify the fetal head positions in vacuum-assisted deliveries. We performed a prospective observational study including 101 pregnant patients in active labor who required a vacuum-assisted delivery. The fetal head position was assessed by a DE and a TUS prior to vacuum cup placement...

PURPOSE: To compare the correlation between 2D transperineal ultrasonography and physical examination (intravaginal palpation) for assessing pelvic floor and levator ani function. METHODS: Due to symptoms of pelvic floor disorder, 40 women between the ages of 29 and 75 were enrolled in this study as candidates for urodynamic and structural evaluation of the pelvic floor. A pelvic floor gynaecologist and radiologist assessed the levator ani function via physical examination (graded based on the Oxford Grading System) and transperineal 2D ultrasound, respectively...

IMPORTANCE: There are limited data to determine the change in severity, efficacy, and mechanism of action of yoga-Pilates in the treatment of stress urinary incontinence (SUI). OBJECTIVES: The primary objective was to evaluate the effect of an 8-week web-based home yoga-Pilates exercise program on SUI severity and to evaluate the potential mechanism of action through ultrasound examination of the urethral rhabdosphincter cross-sectional area. STUDY DESIGN: This was a prospective cohort study of women with SUI...

AIMS: Levator ani deficiency has been implicated in anterior pelvic floor pathology but its association with pelvic floor defaecatory dysfunction is less clear. The aim was to examine the relationship of levator ani deficiency with anatomical abnormalities (rectocoele, intussusception, enterocoele, perineal descent) and patient symptoms (bowel, vagina) in patients with pelvic floor defaecatory dysfunction. METHODS: The prospective observational case series of 223 women presenting to a tertiary colorectal pelvic floor unit with defaecatory dysfunction...

Approaches and techniques used for diagnostic prostate biopsy have undergone considerable evolution over the past few decades: from the original finger-guided techniques to the latest MRI-directed strategies, from aspiration cytology to tissue core sampling, and from transrectal to transperineal approaches. In particular, increased adoption of transperineal biopsy approaches have led to reduced infectious complications and improved antibiotic stewardship. Furthermore, as image fusion has become integral, these novel techniques could be incorporated into prostate biopsy methods in the future, enabling 3D-ultrasonography fusion reconstruction, molecular targeting based on PET imaging and autonomous robotic-assisted biopsy...

INTRODUCTION: Endoanal ultrasound (3D-EAUS) is the gold standard imaging investigation for evaluating the anal sphincter; unfortunately, it is not universally available in most obstetric units. This study aims to appraise the ability of transperineal ultrasound (TPUS) compared with 3D-EAUS as the gold standard to identify anal sphincter defects after primary repair of OASIS. METHODS: A systematic search of major databases to identify diagnostic accuracy of 3D-TPUS in evaluating anal sphincter defects...

OBJECTIVES: To estimate the correlation of cervical dilation between pocket-device point-of-care transperineal ultrasound (TPUS) and digital cervical examination (DCE). METHODS: Laboring pregnant individuals ≥37 weeks of gestation presenting were prospectively evaluated for cervical dilation with a handheld pocket-sized ultrasound (Butterfly iQ+® ) applied to the perineum, with a blinded DCE directly following. Subjects completed a survey to rate pain and for any preference from the examinations...

OBJECTIVE: This study aimed to investigate the anatomical changes in the pelvic floor of women with breast cancer using tamoxifen by transperineal 3D ultrasonography and their effect on the urinary incontinence and sexual dysfunction. METHODS: Ninety-four patients with breast cancer using TAM in the study group and ninety-five healthy women of the same age in the control group were included in this prospective cohort study. Female Sexual Function Index and Incontinence Questionnaire-Short Form scales were applied to both groups...

PURPOSE: To evaluate diagnostic accuracy, safety, and efficiency of an MRI-TRUS fusion-guided transperineal prostate biopsy method in an outpatient setting under local anaesthesia. METHODS: Patients undergoing transperineal prostate biopsy were included from March 2021 to May 2022. Biopsies were performed under local anaesthesia in an outpatient setting, using specialised fusion software. Primary outcome was (clinically significant) cancer detection rate. Secondary outcomes were procedure time, patient discomfort during the procedure and complication rate...

OBJECTIVE: The purpose of this study was to evaluate the role of transrectal, transvaginal, or transperineal ultrasound (US) in evaluation of perianal fistula and to assess the possibility of its role as a first-line investigation for diagnosis and for follow-up as well as a possible substitute for magnetic resonance imaging (MRI). METHODS: This is a retrospective observational study of 200 patients. All the patients complaining of discharging wound, acute or chronic pain in the perianal region and patients suspected clinically having perianal sinus/fistula, referred for ultrasound evaluation were included in the study...

OBJECTIVES: To apply shear wave elastography (SWE) combined with transperineal ultrasonography (TPUS) to study the association between urethral funneling in stress urinary incontinence (SUI) and the biological properties of the urethral rhabdosphincter muscle in women. METHODS: This single-center retrospective study included 166 women with SUI (SUI group) and 185 women who underwent a routine physical examination (control group). The control group and SUI group were divided into nonfunneling and funneling groups according to the presence or absence of urethral funneling, respectively, and their ultrasound findings were compared to analyze the association between funneling and ultrasound measurements...

We present a case of a 12.5-year-old girl who has suffered from recurrent urinary tract infections for many years but has never undergone a detailed diagnostic process. Only as a teenager did she complain of acute pain in her lower abdomen and it turned out that her genital organs had not properly developed. She had an obstructive defect in the reproductive tract. When there was a significant amount of discharge collected in the lumen of the genital tract and the organs had distended, acute pain appeared, which allowed us to make the diagnosis...

BACKGROUND: Multiparametric magnetic resonance imaging (mpMRI) and targeted biopsy (TB) facilitate accurate detection of clinically significant prostate cancer (csPC). However, it remains unclear how targeted cores should be applied for accurate diagnosis of csPC. OBJECTIVE: To assess csPC detection rates for two target-directed MRI/transrectal ultrasonography (TRUS) fusion biopsy approaches, conventional TB and target saturation biopsy (TS). DESIGN, SETTING, AND PARTICIPANTS: This was a prospective single-center study of outcomes for transperineal MRI/TRUS fusion biopsies for 170 men...

PURPOSE: This study assessed the performance of transperineal ultrasonography (TPUS) in evaluating the treatment response in children with perianal Crohn's disease (PACD) compared with pelvic magnetic resonance imaging (MRI). METHODS: This retrospective study was approved by the Institutional Review Board of our institution, which waived the requirement for informed consent. Twenty-nine patients (19 boys and 10 girls; median age, 14 years [range, 8 to 18 years]) with 56 fistulas were examined...

OBJECTIVE: To determine whether clinical or radiological parameters can predict clinically significant prostate cancer (csPC) in patients with the Prostate Imaging Reporting and Data System (PI-RADS) 3 lesions. PATIENTS AND METHODS: Data were obtained from 247 patients with PI-RADS 3 lesions on mpMRI and who had received a software guided transperineal/transrectal MRI/transrectal ultrasonography (MRI/TRUS) fusion prostate biopsy with concomitant standard systematic 12-core biopsy following mpMRI in the prostate cancer and prostate biopsy database of Turkish Urooncology Association, between 2016 and 2020...

OBJECTIVES: Obstetrical anal sphincter injuries (OASIS) are complications of vaginal delivery. Unrepaired anal sphincter after delivery increases the risk of anal incontinence. The aim of our study is to search for residual defect after OASI repair by 4D introital ultrasound (US). We hypothesised that imaging prior to hospital discharge would show the same number of defects as assessment at 3 months. STUDY DESIGN: This is a retrospective analysis of 138 patients with immediate repair after OASIS...

PURPOSE: Pelvic sidewall recurrence after hysterectomy for uterine malignances has a poor prognosis, and the salvage therapy for this type of recurrence is still challenging. The purpose of this study was to investigate the efficacy of freehand high-dose-rate interstitial brachytherapy (HDR-ISBT) through the perineum using transrectal ultrasonography for this disease. METHODS AND MATERIALS: We retrospectively evaluated 42 patients with pelvic sidewall recurrence after hysterectomy for uterine cervical and endometrial cancers...
