Gender and racial diversity among plenary session speakers at the Society of Abdominal Radiology Annual Meetings: a five-year assessment.

PURPOSE: To evaluate the gender and racial diversity of plenary session speakers in the annual meetings of Society of Abdominal Radiology (SAR) over 2016 to 2020. MATERIALS AND METHODS: The brochures of the SAR annual meetings were reviewed for plenary session speakers and titles. Publicly available institutional profiles and social media were reviewed by the investigator in order to infer gender and race. Gender assessments were men, women, transgender men, transgender women or gender non-binary. Race was classified as White, Black or African American, American Indians and Alaskan Natives, Asian, Native Hawaiian and Pacific Islander and Multiracial. Statistical analysis was performed using chi square and T-tests. RESULTS: Based on self-reported data, the SAR has 64% male and 36% female members. Over 2016-2020, plenary session speakers were more likely to be men [69.6% (183/263)] than women [30.4% (80/263)] (p-value = 0.0007). No speakers could be reliably identified as transgender, gender non-binary or gender expansive. In 2016, there were 24% women plenary speakers. This proportion was 28% in 2017, 33% in 2018 and 36% in 2019, and 30% in 2020. When assessing racial distribution, white speakers accounted for the majority of plenary speakers, ranging from 61 to 78%. Asians speakers accounted for 22 to 35%. There were no Black and African American, American Indian & Alaskan Native, Native Hawaiian & Pacific Islander plenary speakers (0%). Multiracial speakers were represented from 2018 to 2020, accounting for 2-4% speakers (p-value < 0.0001). CONCLUSIONS: Plenary speakers at SAR Annual Meetings from 2016-2020 were more likely to be men, but with the proportion of women presenters increasing over time. White speakers represented the majority of plenary session speakers, followed by Asians. No plenary session speakers were identified as Black or African American or Native Americans.

Imaging in scrotal trauma: a European Society of Urogenital Radiology Scrotal and Penile Imaging Working Group (ESUR-SPIWG) position statement.

Imaging plays a crucial role in the evaluation of scrotal trauma. Among the imaging modalities, greyscale ultrasound and Colour Doppler ultrasound (CDUS) are the primary techniques with the selective utilisation of advanced techniques such as contrast-enhanced ultrasound (CEUS) and elastography. Despite ultrasound being the mainstay of imaging scrotal trauma, its diagnostic performance is not fully established. Considering these difficulties and their impact on clinical practice, the Scrotal and Penile Imaging Working Group of the European Society of Urogenital Radiology (ESUR-SPIWG) established an expert task force to review the current literature and consolidate their expertise on examination standards and imaging appearances of various entities in scrotal trauma. This paper provides the position statements agreed on by the task force with the aim of providing guidance for the use of imaging especially multiparametric US in scrotal trauma.Key Points• Greyscale and Colour Doppler ultrasound are the mainstay of imaging in patients with scrotal trauma.• Contrast-enhanced ultrasound and elastography are the advanced techniques useful as a problem-solving modality in equivocal cases.• This paper summarises the position statements of the ESUR-SPIWG on the appropriate utilisation of multiparametric ultrasound and other imaging modalities in the evaluation of scrotal trauma.

Post-cystectomy Enterocele: A Case Series and Review of the Literature.

OBJECTIVE: To present a case series and literature review on post radical cystectomy (RC) pelvic organ prolapse (POP) to heighten awareness of the symptoms, imaging findings, and risk factors associated with this complication and discuss opportunities for prevention. Women with muscle invasive bladder cancer undergo RC with anterior exenteration, significantly disrupting the pelvic floor. These women are at risk for POP. METHODS: We present 4 cases of high-grade POP in women who underwent RC for bladder cancer. We reviewed the literature by conducting a Boolean search in PubMed with the terms "("radical cystectomy") AND ("enterocele" OR "pelvic organ prolapse" OR "rectocele" OR "vaginal vault prolapse")." RESULTS: All 4 women reported a bulge sensation in the vagina and physical exam confirmed POP. Three had radiographic findings consistent with high-grade enterocele at rest. Three experienced prolonged intra-abdominal pressure rise post-RC that may have further weakened pelvic floor support, while the fourth had a history of surgery for high-grade POP. Nine articles on POP following RC were identified. Four focused on treatment and 3 focused on prevention. CONCLUSION: Administration of a single validated question would have identified all 4 cases of postoperative enterocele and is sensitive to detect most women who are experiencing POP. Attention to the pelvic floor on cross-sectional imaging with identification of features that indicate POP, such as herniation of intestinal contents below the pubo-coccygeal line, will identify and/or confirm high-grade enterocele. Familiarity with risk factors for POP and identification of weakened vaginal wall support opens up the opportunity for prevention.

Ultrasound evaluation of varicoceles: systematic literature review and rationale of the ESUR-SPIWG Guidelines and Recommendations.

Although often asymptomatic and detected incidentally, varicocele is a relatively common problem in patients who seek medical attention for infertility problems. Ultrasound (US) is the imaging modality of choice for evaluation, but there is no consensus on the diagnostic criteria, classification, and examination technique. In view of this uncertainty, the Scrotal and Penile Imaging Working Group of the European Society of Urogenital Radiology (ESUR-SPIWG) undertook a systematic review of the available literature on this topic, to use as the basis for evidence-based guidelines and recommendations. This paper provides the results of the systematic review on which guidelines were constructed.

Ultrasound evaluation of varicoceles: guidelines and recommendations of the European Society of Urogenital Radiology Scrotal and Penile Imaging Working Group (ESUR-SPIWG) for detection, classification, and grading.

Varicoceles are relatively common particularly in asymptomatic men and are even more prevalent in subfertile men, representing the most common potentially correctable cause of male infertility. Ultrasound (US) is the imaging modality of choice for varicocele evaluation, but there is no widely accepted consensus on examination technique, diagnostic criteria, or classification. In view of this uncertainty, the guideline writing group (WG) of the European Society of Urogenital Radiology (ESUR) Scrotal and Penile Imaging Working Group (ESUR-SPIWG) undertook a literature review and assessment of the quality of relevant evidence. The group then produced evidence-based recommendations for varicocele US examination, interpretation, and classification by consensus agreement. The results are presented in the form of 15 clinical questions with a brief summary of the relevant evidence and the authorised recommendations from the SPIWG. This paper provides a short summary of the evidence evaluation and the complete recommendations.Key Points• Varicocele is a common clinical problem; it is highly prevalent amongst subfertile men and the most common potentially correctable cause of male infertility. • Ultrasound is the imaging modality of choice for varicocele assessment, but there is no generally agreed consensus on the US examination technique or the criteria that should be used for diagnosis, grading, and classification. • This paper summarises the recommendations of the ESUR-SPIWG for standardising the US assessment of varicoceles. This includes examination technique, image interpretation, classification, and reporting.

Imaging of the adult male urethra, penile prostheses and artificial urinary sphincters.

To discuss the imaging appearances of various pathologies affecting adult male urethra and to review the role of imaging in the assessment of artificial urinary sphincters and penile prostheses. Diagnosis of common male urethral diseases heavily depends on two conventional fluoroscopic techniques namely retrograde urethrography and voiding cystourethrography. These are useful in evaluating common urethral diseases like traumatic injury, infections, and strictures. Cross-sectional imaging can be useful in evaluating periurethral pathologies. Artificial urinary sphincters, slings, and periurethral bulking agents are used in the management of urinary incontinence and imaging can be utilized to detect complications in these devices. Cross-sectional imaging especially MRI plays a significant role in evaluating the different types of penile prostheses and their malfunctioning.

Hydrosalpinx in patients with hysterectomy without salpingo-oophorectomy referred for pelvic magnetic resonance imaging.

OBJECTIVE: Women with ovarian-sparing hysterectomy before 2007 are more likely to have retained Fallopian tube remnants which can become fluid-filled, distended masses, potentially mistaken for a cystic adnexal neoplasm on imaging. Here we assess the prevalence and appearance of hydrosalpinx in women with ovarian-sparing hysterectomy prior to 2007 referred for pelvic MRI. METHODS: A total of 3044 consecutive pelvic MRI exams performed over a two-year period (2003-2004) were selected from our radiology database and retrospectively reviewed. Examinations performed on male patients (N = 858), duplicate examinations on the same patient (N = 675) and examinations performed for MR guided biopsy (N = 1) were excluded from the study. From the remaining female pelvic MRI examinations (N = 1510), patients with hysterectomy without oophorectomy were identified. The frequency of hydrosalpinx in this population was then determined visually by two experienced radiologists and kappa analysis was then performed to assess for interobserver agreement. RESULTS: Of the 3044 pelvic MRI examinations, 1510 were performed on females and 76 (5%) of these women had ovarian-sparing hysterectomy. Of these 76 women, 14 patients (18%) had hydrosalpinx (kappa = 0.8) of which 11 were unilateral and 3 bilateral. A total of 9 of the 14 cases positive for hydrosalpinx in patients with ovarian-sparing hysterectomy were referred to MRI for evaluation of cystic adnexal masses detected on other modalities. CONCLUSION: Hydrosalpinx should be considered in the differential diagnosis of cystic adnexal lesions in women with prior hysterectomy and retained ovaries.

Ureteral pseudodiverticulosis and urothelial cell carcinoma: rethinking the association.

PURPOSE: To compare frequency of new and recurrent urothelial cell carcinoma (UCC) among patients with and without pseudodiverticulosis on imaging. METHODS: This retrospective case-control study compared all 113 sequential patients with ureteral pseudodiverticulosis on radiographic urography between 1/1/2002 and 12/31/2012. Six patients were lost to follow-up. 107 patients without pseudodiverticulosis were matched by imaging modality, clinical indication, and tumor grade. Known UCC and primary outcome of new or recurrent UCC were determined through pathology on cystoscopy or clinical follow-up. RESULTS: Nearly half of patients with pseudodiverticulosis had known UCC at the time of imaging (49/107, 46%). Mean cystoscopy follow-up was 7.0 and 4.6 years for pseudodiverticulosis cases with and without known UCC, respectively, and 7.5 and 7.3 years for controls, respectively. Mean clinic follow-up was 7.5 and 6.0 years for pseudodiverticulosis cases with and without known UCC, respectively, and 6.4 and 7.6 years for controls, respectively. Among patients with known UCC at the time of imaging, similar rates of recurrent UCC were demonstrated on follow-up among patients with pseudodiverticulosis (6/49, 12%) and without (7/49, 14%). Among patients with no known history of UCC at the time of imaging, no patients with pseudodiverticulosis developed UCC on follow-up and 5% (3/58) of patients without pseudodiverticulosis developed UCC. CONCLUSION: Although half of patients with ureteral pseudodiverticulosis have a known diagnosis of UCC, the presence of pseudodiverticulosis did not signify an increased likelihood of developing new or recurrent UCC over the follow-up period.

Sonographically indeterminate scrotal masses: how MRI helps in characterization.

Magnetic resonance imaging (MRI) of the scrotum represents a useful supplemental imaging technique in the characterization of scrotal masses, particularly recommended in cases of nondiagnostic ultrasonographic findings. An accurate characterization of the benign nature of scrotal masses, including both intratesticular and paratesticular ones may improve patient management and decrease the number of unnecessary radical surgical procedures. Alternative treatment strategies, including follow-up, lesion biopsy, tumor enucleation, or organ sparing surgery may be recommended. The aim of this pictorial review is to present how MRI helps in the characterization of sonographically indeterminate scrotal masses and to emphasize the key MRI features of benign scrotal masses.

CT and MR Imaging Features of Artificial Urinary Sphincters, Penile Prostheses, and Other Devices in the Male Lower Genitourinary Tract.

Urinary incontinence and erectile dysfunction are relatively common conditions in the aging male population. Surgical interventions for urinary incontinence include placement of an artificial urinary sphincter (AUS), perineal sling, or sacral nerve stimulator and injections of periurethral bulking agents. Erectile dysfunction can be treated surgically with placement of a penile prosthesis. The complications of these devices can be broadly categorized as device component malposition, malfunction, and infection. This article focuses on AUSs, penile prostheses, and their complications. Familiarity with these devices and their complications allows the radiologist to effectively describe these implants in radiologic reports and to recognize complications when they occur. This article reviews the normal cross-sectional radiologic appearance of the most common implants used to surgically treat male urinary incontinence and erectile dysfunction, as well as the potential complications associated with these devices. ©RSNA, 2018.

Comprehensive Multimodality Imaging Review of Complications of Penile Prostheses.

OBJECTIVE: The objective of our article is to review the role of imaging in the diagnosis of various complications of a penile prosthesis (PP). CONCLUSION: Complications of a PP can be categorized into three groups: first, malpositioning, which includes buckling, floppy glans, erosion, migration, and crossover; second, mechanical failure, which includes fracture, aneurysm, and leakage; and, third, infection. Radiography, sonography, CT, and MRI are useful in the detection of these complications and complement each other, with MRI being the most useful imaging modality among them.

Introduction to Imaging of Penile Prostheses: A Primer for the Radiologist.

OBJECTIVE: The purpose of this article is to provide radiologists with an introduction to the imaging appearances of various types of penile prostheses and discuss imaging pitfalls. CONCLUSION: Two major types of penile prostheses currently are in use: malleable penile prostheses and inflatable penile prostheses. Sonography is useful in the assessment of the pelvic reservoir and scrotal pump. MRI helps in the complete evaluation of all the prosthetic components, making it a "one-stop shop" imaging technique.

MRI of the scrotum: Recommendations of the ESUR Scrotal and Penile Imaging Working Group.

OBJECTIVES: The Scrotal and Penile Imaging Working Group (SPI-WG) appointed by the board of the European Society of Urogenital Radiology (ESUR) has produced recommendations for magnetic resonance imaging (MRI) of the scrotum. METHODS: The SPI-WG searched for original and review articles published before September 2016 using the Pubmed and Medline databases. Keywords used were 'magnetic resonance imaging', 'testis or testicle or testicular', 'scrotum', 'intratesticular', 'paratesticular', 'extratesticular' 'diffusion-weighted', 'dynamic MRI'. Consensus was obtained among the members of the subcommittee. The expert panel proposed recommendations using Oxford Centre for Evidence-Based Medicine 2011 Levels of Evidence. RESULTS: The recommended MRI protocol should include T1-, T2-weighted imaging, diffusion-weighted imaging and dynamic contrast-enhanced MRI. Scrotal MRI can be clinically applied for lesion characterisation (primary), including both intratesticular and paratesticular masses, differentiation between germ-cell and non-germ-cell neoplasms (evolving), characterisation of the histological type of testicular germ cell neoplasms (TGCNs, in selected cases), local staging of TGCNs (primary), acute scrotum (in selected cases), trauma (in selected cases) and undescended testes (primary). CONCLUSIONS: The ESUR SPI-WG produced this consensus paper in which the existing literature on MRI of the scrotum is reviewed. The recommendations for the optimal imaging technique and clinical indications are presented. KEY POINTS: • This report presents recommendations for magnetic resonance imaging (MRI) of the scrotum. • Imaging acquisition protocols and clinical indications are provided. • MRI is becoming established as a worthwhile second-line diagnostic tool for scrotal pathology.

Imaging Features of Paratesticular Masses.

In this pictorial essay, we review the sonographic and other imaging findings of paratesticular masses in correlation with the pathologic findings. The examples include benign and malignant tumors and also non-neoplastic mass lesions of the paratesticular structures. Diagnostic sonographic findings of these mass lesions as well as correlative findings of other imaging methods are presented.

Incidentally detected non-palpable testicular tumours in adults at scrotal ultrasound: impact of radiological findings on management Radiologic review and recommendations of the ESUR scrotal imaging subcommittee.

OBJECTIVES: The increasing detection of small testicular lesions by ultrasound (US) in adults can lead to unnecessary orchiectomies. This article describes their nature, reviews the available literature on this subject and illustrates some classical lesions. We also suggest recommendations to help characterization and management. METHODS: The ESUR scrotal imaging subcommittee searched for original and review articles published before May 2015 using the Pubmed and Medline databases. Key words used were 'testicular ultrasound', 'contrast-enhanced sonography', 'sonoelastography', 'magnetic resonance imaging', 'testis-sparing surgery', 'testis imaging', 'Leydig cell tumour', 'testicular cyst'. Consensus was obtained amongst the members of the subcommittee, urologist and medical oncologist. RESULTS: Simple cysts are frequent and benign, and do not require follow up or surgery. Incidentally discovered small solid testicular lesions detected are benign in up to 80 %, with Leydig cell tumours being the most frequent. However, the presence of microliths, macrocalcifications and hypoechoic areas surrounding the nodule are findings suggestive of malignant disease. CONCLUSION: Asymptomatic small testicular lesions found on ultrasound are mainly benign, but findings such as microliths or hypoechoic regions surrounding the nodules may indicate malignancy. Colour Doppler US remains the basic examination for characterization. The role of newer imaging modalities in characterization is evolving. KEY POINTS: • Characterization of testicular lesions is primarily based on US examination. • The role of MRI, sonoelastography, contrast-enhanced ultrasound is evolving. • Most small non-palpable testicular lesions seen on ultrasound are benign simple cysts. • Leydig cell tumours are the most frequent benign lesions. • Associated findings like microliths or hypoechoic regions may indicate malignancy.

Evaluation of the patient with asymptomatic microscopic hematuria.

Asymptomatic microscopic hematuria (AMH) is relatively common in clinical practice but the etiology remains unclear in the majority of patients; it is rarely related to genitourinary malignancies. The 2012 guidelines of the American Urological Association recommend an evaluation after a single positive urinalysis with mandatory upper tract evaluation in all patients, preferably with CT urography (CTU). The likelihood of detecting significant upper track abnormalities, particularly malignancies is low with CTU, while incidental extraurinary abnormalities are often found, the majority of which are not clinically significant. The workup for these incidental findings has significant financial and clinical implications. Primary care physicians, who are most apt to encounter patients with AMH, have a low rate of adherence to the AUA guidelines, possibly as a result of the broadening of criteria for AMH evaluation by the AUA, with resultant uncertainty amongst primary care physicians about the appropriate candidates for such evaluation. Selection of subgroups of patients with risk factors for GU malignancies who may benefit from a complete evaluation is essential, as opposed to evaluation of all patients classified as having AMH.
