Uncontrolled hemorrhage secondary to unstable pelvic fractures is a preventable cause of prehospital death in the military and civilian sectors. Because the mortality rate associated with unstable pelvic ring injuries exceeds 50%, the use of external compression devices for associated hemorrhage control is paramount. During mass casualty incidents and in austere settings, the need for multiple external compression devices may arise. In assessing the efficacy of these devices, the magnitude of applied force has been offered as a surrogate measure of pubic symphysis diastasis reduction and subsequent hemostasis. This study offers a sensor-circuit assessment of applied force for a convenience sample of pelvic compression devices. The SAM® (structural aluminum malleable) Pelvic Sling II (SAM Medical) and improvised compression devices, including a SAM Splint tightened by a Combat Application Tourniquet® (C-A-T; North American Rescue) and a SAM® Splint tightened by a cravat, as well as two joined cravats and a standard-issue military belt, were assessed in male and female subjects. As hypothesized, compressive forces applied to the pelvis did not vary significantly based on device operator, subject sex, and subject body fat percentage. The use of the military belt as an improvised method to obtain pelvic stabilization is not advised.

PURPOSE
The purpose of this study was to compare patients with traumatic pelvic ring injuries sustained in road and mountain bicycling accidents to evaluate for differences in injury types and hospital courses.
METHODS
A retrospective review of 60 patients presenting with pelvic ring injuries after road (n = 46) and mountain (n = 14) bicycling accidents was performed to compare patient/injury characteristics and hospital course.
RESULTS
LC1 injuries were the most common pelvic ring injury (n = 31, 51.7%), 38.7% (n = 12) of which were considered unstable, followed by isolated iliac wing (n = 11, 18.3%), pubic rami (n = 6, 10.0%), and sacral fractures (n = 6, 10.0%). Hospital admission was required for 41 (68.3%) patients. The median hospital LOS was 4 days (IQR 2-9) and 12 (20%) patients received operative treatment. Patients in road versus mountain bicycling accidents were more likely to be older tobacco users and were similar in sex, body mass index, and injury severity score. Road bicycling resulted in more LC1 injuries (58.7% vs 28.6%, p = 0.04), while mountain bicycling resulted in more iliac wing fractures (42.9% vs. 10.9%, p = 0.01). Road cycling injuries required more days in the hospital to clear PT (median difference 2, CI 0-4, p = 0.04) and had longer hospital stays (median difference 2, CI 0-6, p = 0.02) but had no difference in the rate of admission, operative intervention, or discharge to rehabilitation facilities.
CONCLUSION
The majority of pelvic ring injuries from road and mountain bicycling accidents were LC1 injuries that were frequently unstable and often required hospital admission and operative fixation.

IMPORTANCE
Understanding patients' perceptions of symptoms and outcomes of urogynecologic surgery is essential for providing high-quality care.
OBJECTIVE
The aim of the study was to assess association of pain catastrophizing with pelvic floor symptom distress and impact, postoperative pain, and voiding trial in patients undergoing urogynecologic surgery.
STUDY DESIGN
Individuals whose self-identified gender was female and were undergoing surgery March 2020-December 2021 were included. Participants completed the Pain Catastrophizing Scale (range 0-52), Pelvic Floor Distress Inventory, and Pelvic Floor Impact Questionnaire preoperatively. Pain catastrophizing was score ≥30 and describes the tendency to magnify the overall threat of pain. Voiding trial failure was inability to void ≥2/3 of instilled volume (≤300 mL). The association between pain catastrophizing and symptom distress and impact was assessed with linear regression. A P < 0.05 is significant.
RESULTS
Three hundred twenty patients were included (mean age, 60 years, 87% White). Forty-six of 320 participants (14%) had a pain catastrophizing score ≥30. The pain catastrophizing group had higher body mass index (33 ± 12 vs 29 ± 5), more benzodiazepine use (26% vs 12%), greater symptom distress (154 ± 58 vs 108 ± 60), and greater urogenital (59 ± 29 vs 47 ± 28), colorectal (42 ± 24 vs 26 ± 23), and prolapse (54 ± 24 vs 36 ± 24) subscale scores, all P ≤ 0.02. The pain catastrophizing group had greater impact (153 ± 72 vs 72 ± 64, P < 0.01) and urogenital (60 ± 29 vs 34 ± 28), colorectal (36 ± 33 vs 16 ± 26), and prolapse (57 ± 32 vs 22 ± 27) subscale scores, P < 0.01. Associations remained controlling for confounders ( P < 0.01). The pain catastrophizing group had higher 10-point pain scores (8 vs 6, P < 0.01) and was more likely to report pain at 2 weeks (59% vs 20%, P < 0.01) and 3 months (25% vs 6%, P = 0.01). Voiding trial failure did not differ (26% vs 28%, P = 0.98).
CONCLUSIONS
Pain catastrophizing is associated with greater pelvic floor symptom distress and impact and postoperative pain but not voiding trial failure.

Observational Study
INTRODUCTION AND HYPOTHESIS
Striae gravidarum are linear atrophic scars appearing on the abdomen of pregnant women reported to be related to pregnancy-induced changes in the connective tissue. Pelvic floor distress symptoms are also known to be linked to connective tissue weakness. Given that common pathophysiological pathways may play a role in both striae gravidarum and pelvic floor dysfunction symptoms, we sought to examine whether there is a correlation between them during pregnancy.
METHODS
A prospective observational study among third-trimester pregnant women who visited a tertiary medical center for routine pregnancy follow-up was conducted by using the Pelvic Floor Distress Inventory (PFDI-20) questionnaire to evaluate pelvic floor distress symptoms and the Davey method for evaluating striae gravidarum severity. Obstetrical characteristics as well as pelvic floor distress symptoms were compared between two groups according to the severity of striae gravidarum. Univariate analysis was carried out using appropriate tests; PFDI scores were compared between the groups using the Mann-Whitney test.
RESULTS
Women with striae gravidarum were significantly older (31.06 vs. 28.83 years, p < 0.01), had a lower body mass index (27.5 vs. 30.98, p < 0.01), and gave birth to smaller neonates (3155 vs. 3389 g, p < 0.01). In addition, the overall and median PFDI-20 scores differed between the groups (with severe SG having the highest median score of 20 and those with milder SG having a score of 16 compared to 14 in those without SG). A distinct association between the PFDI-20 score and SG severity was not demonstrated (p = 0.63).
CONCLUSIONS
In our population, an association was demonstrated between pelvic floor distress symptoms and the presence of striae gravidarum. However, following a linear regression model, no statistically significant association between SG severity and total PFD-20 score was seen. Our findings strengthen the hypothesis of common connective tissue involvement in the pathophysiology of both conditions.

Review
Most pelvic tumors originate from the organs. Less commonly, tumors can arise from the various anatomic pelvic compartments and are comprised of mesenchymal tissue: muscles, connective tissue, vessels, lymphatics, and fat. Among some of the rarer entities are benign tumors (eg, angiomyxoma, cellular angiofibroma, and desmoid fibromatosis), malignant tumors (eg, sarcoma), and tumors that can manifest as benign or malignant (eg, solitary fibrous tumor or nerve sheath tumor). Because these tumors are uncommon and often manifest with nonspecific clinical features, imaging (usually MRI) is an initial step in the evaluation. Radiologists interpreting these images are asked to help narrow the differential diagnosis and assess the likelihood of malignancy for treatment planning. Thus, the MRI report should include the imaging features that would indicate the underlying tissue histology for pathologic diagnosis as well as a description of the anatomic extent and pattern of growth. The authors describe multiple locally aggressive benign and malignant mesenchymal tumors and highlight characteristic clinical and imaging features that enable the radiologist to narrow the differential diagnosis. The anatomic spaces of the pelvis are reviewed with illustrations to aid the radiologist in describing these tumors, which often span multiple pelvic compartments. Tumor appearance at T2-weighted, diffusion-weighted, and postcontrast MRI is summarized and illustrated with correlation at CT or fluorodeoxyglucose PET/CT, when available. MRI features that correspond to specific types of tissue (eg, myxoid, fibrous, or vascular) are highlighted and correlated with images from pathologic evaluation. RSNA, 2021.

Review
BACKGROUND
Immunoglobulin G4-related disease (IgG4-RD) is a systemic, immune-mediated disease that can affect multiple organs, including the orbits, salivary glands, thyroid gland, lungs, aorta, pancreas, bile ducts, lymph nodes, and retroperitoneum. While timely diagnosis is particularly important given the efficacy of glucocorticoid treatment for IgG4-RD, accurate recognition can prove a challenge given the overlap between the imaging features of this disease and other entities.
PURPOSE
After a review of the epidemiology, pathophysiology, and clinical considerations (including treatment) associated with IgG4-RD, this pictorial review will showcase the variable imaging manifestations of this disease in the abdomen and pelvis. Post-treatment imaging appearance of these entities will be reviewed and mimickers of this disease in the abdomen and pelvis will be presented.
CONCLUSION
The presence of mass-like soft tissue with radiographic characteristics of fibrosis affecting multiple organs should raise suspicion for IgG4-RD, although definite diagnosis can only be made with appropriate clinical, serological, and pathologic data.

BACKGROUND AND PURPOSE
There is growing evidence on the role of carbon-ion radiotherapy (C-ion RT) for gynaecological tumours. Pelvic insufficiency fracture (PIF) decreases the quality of life after photon beam radiotherapy (RT). However, there is little information on PIF after C-ion RT. This study retrospectively assessed incidence of PIF after C-ion RT for uterine carcinomas (UCs) and the associations of clinical and dosimetric parameters with PIF incidence.
MATERIAL AND METHODS
We performed a pooled analysis of 102 patients with UCs who underwent definitive C-ion RT alone and were followed up for >6 months without any additional RT in the pelvic region. PIF occurrence was surveyed using magnetic resonance imaging and/or computed tomography. Associations of clinical and dosimetric parameters with PIF incidence were analysed.
RESULTS
The 2- and 5-year actuarial incidences of ≥grade 1 PIF in all pelvic regions were 22.3% and 42.4%, respectively. The most frequent site of involvement was the sacrum. Log-rank tests showed that higher volumes receiving >10 Gy (relative biological effectiveness) (V10), V20, V30, and V40, body mass index (BMI) under 18.5, and current smoking were associated with increased incidence of ≥grade 1 PIF in the sacrum.
CONCLUSIONS
We clarified the actuarial incidence of PIF after C-ion RT for UCs. Higher V10, V20, V30, V40, D, D, current smoking, BMI <18.5, and using the anterior-posterior direction in whole pelvic irradiation were associated with higher incidences of PIF in the sacrum. The present results may lead to further improvement of C-ion RT for UCs.

INTRODUCTION AND HYPOTHESIS
The aim was to develop and validate (internally and externally) a prediction model for the presence and diagnosis of pelvic floor dysfunction (PFD) in women, including pelvic organ prolapse, stress urinary incontinence and/or overactive bladder via a patient-completed online tool.
METHODS
Using a retrospective cohort of women aged >18 years, from multiple tertiary gynaecology units within Queensland, Australia (2014-2018), the prediction model was developed via penalized logistic regression with internal and external validation utilizing multiple clinical predictors (42 questions from the Australian Pelvic Floor Questionnaire and demographics: age, body mass index, parity and mode of delivery). The main outcome measures were the accuracy of the model in predicting a diagnosis of pelvic floor dysfunction and its specific conditions of prolapse and incontinence.
RESULTS
A total of 3,501 women were utilized for model development and internal validation and 449 for external validation. On internal validation the model correctly identified those with PFD with 97% sensitivity, 74% specificity and a concordance index (C-index) of 0.96. Predictions of pelvic organ prolapse were also accurate, with 86% sensitivity, 83% specificity, C-index 0.83, as was stress urinary incontinence, 84% sensitivity, 87% specificity, C-index 0.87, and overactive bladder, 76% sensitivity, 77% specificity, C-index 0.77. External validation confirmed the model's accuracy with a similar C-index in all parameters.
CONCLUSIONS
This model provides an accurate online tool to differentiate between those with and without PFD and diagnoses of common pelvic floor disorders. It serves as a valuable self-assessment for women and primary care providers.

Observational Study
INTRODUCTION AND HYPOTHESIS
There is a complex relationship between obesity and pelvic organ prolapse. The objective of our study was to evaluate whether body mass index (BMI) changes the relationship between signs and symptoms of prolapse.
METHODS
This was a retrospective observational study based on datasets of women seen in a tertiary urogynecological center with symptoms of pelvic floor and lower urinary tract dysfunction between April 2012 and October 2015. Patients underwent a structured interview, clinical examination (based on the POP-Q) and 4D transperineal ultrasound (TPUS). Offline assessment of sonographic organ descent was undertaken later, blinded to all patient data.
RESULTS
Weight and BMI affect the relationship between symptoms and signs of prolapse. This effect is statistically highly significant. The more obese a patient is, the less likely she is to notice a given degree of objective prolapse, regardless of whether it is diagnosed clinically or on imaging.
CONCLUSIONS
In this retrospective study, we found a highly significant effect of weight and BMI on prolapse perception in the sense that obesity seems to mask prolapse while a low BMI increases the likelihood of a given degree of prolapse being noticed by the patient.

Review
Pelvic masses can present a diagnostic challenge owing to the difficulty in assessing their origin and the overlap in imaging features. The majority of pelvic tumors arise from gastrointestinal or genitourinary organs, with less common sites of origin including the connective tissues, nerves, and lymphovascular structures. Lesion evaluation usually starts with clinical assessment followed by imaging, or the lesion may be an incidental finding at imaging performed for other clinical indications. Since accurate diagnosis is essential for optimal management, imaging is useful for suggesting the correct diagnosis or narrowing the differential possibilities and distinguishing tumors from their mimics. Some masses may require histologic confirmation of the diagnosis with biopsy and/or up-front surgical resection. In this case, imaging is essential for presurgical planning to assess mass size and location, evaluate the relationship to adjacent pelvic structures, and narrow differential possibilities. Pelvic US is often the first imaging modality performed in women with pelvic symptoms. While US is often useful to detect a pelvic mass, it has significant limitations in assessing masses located deep in the pelvis or near gas-filled organs. CT also has limited value in the pelvis owing to its inferior soft-tissue contrast. MRI is frequently the optimal imaging modality, as it offers both multiplanar capability and excellent soft-tissue contrast. This article highlights the normal anatomy of the pelvic spaces in the female pelvis and focuses on MRI features of common tumors and tumor mimics that arise in these spaces. It provides an interpretative algorithm for approaching an unknown pelvic lesion at MRI. It also discusses surgical management, emphasizing the value of MRI as a road map to surgery and highlighting anatomic locations where surgical resection may present a challenge. RSNA, 2019.
