Abstract
INTRODUCTION Testicular torsion is a serious condition that carries with it a high rate of morbidity. OBJECTIVE This review highlights the pearls and pitfalls of testicular torsion, including presentation, diagnosis, and management in the emergency department (ED) based on current evidence. DISCUSSION Testicular torsion is a urological emergency that occurs with rotation of the testicle along its supporting ligaments leading to obstruction of vascular flow. A key risk factor is the presence of a bell-clapper deformity. The most common population affected includes children in a bimodal distribution with the most cases occurring in the first year of life and between 12 and 18 years, although cases do occur in adults. Acute, severe, unilateral scrotal pain is the most common presenting symptom. Nausea and vomiting are common, but the presence or absence of a cremasteric reflex is not a reliable indicator of disease. The TWIST score may assist with clinical decision making in patients presenting with acute testicular pain but should not be used in isolation. If torsion is suspected or confirmed, consultation with the urology specialist should not be delayed, as outcomes are time sensitive. Ultrasound can be used for diagnosis, but a normal ultrasound examination cannot exclude the diagnosis. Treatment includes emergent urology consultation for surgical exploration and detorsion, as well as symptomatic therapy in the ED. Manual detorsion can be attempted in the ED while awaiting transfer or consultation. CONCLUSIONS An understanding of testicular torsion can assist emergency clinicians in diagnosing and managing this disease.

Abstract
BACKGROUND Previous studies have examined the utility of ultrasonography performed by radiologists for diagnosing paediatric testicular torsion. While point-of-care ultrasound (POCUS) is used in paediatric emergency medicine, its diagnostic accuracy is still unknown. OBJECTIVES The present systematic review and meta-analysis aimed to clarify the accuracy of POCUS in diagnosing testicular torsion in children. METHODS Following the Preferred Reporting Items for Systematic Review and Meta-analysis of Diagnostic Test Accuracy guidelines, a systematic review was performed using the indices of MEDLINE, EMBASE plus EMBASE classics, PubMed and the Cochrane database from inception to November 2020. Any study investigating the diagnostic accuracy of POCUS for paediatric testicular torsion was extracted. The primary outcome was the assessment of the diagnostic accuracy of POCUS for paediatric testicular torsion. The pooled sensitivity and specificity were calculated. Quality analysis was conducted using Quality Assessment of Diagnostic Accuracy Studies-2 (QUADAS-2). RESULTS Four studies enrolling 784 patients in total were included. The pooled sensitivity, specificity, and positive and negative likelihood ratios of POCUS were 98.4% (95% CI: 88.5% to 99.8%), 97.2% (95% CI: 87.2% to 99.4%), 34.7 (95% CI: 7.4 to 164.4) and 0.017 (95% CI: 0.002 to 0.12), respectively. Risk-of-bias assessment using QUADAS-2 revealed that two of the studies had a high risk of bias in patient selection. CONCLUSION The present systematic review and meta-analysis showed that POCUS had high sensitivity and specificity for identifying testicular torsion in paediatric patients although the risk of bias was high in the studies analysed.

Abstract
INTRODUCTION Preservation of the testicle is directly associated with the duration of torsion. The aim in this retrospective study was to identify factors that influence pre-and in-hospital times and measure the extent to which these times affect testicle survival. PATIENTS AND METHODS A retrospective review of 116 patients who underwent exploration for testicular torsion between 2000 and 2015. Patients were divided into orchiectomy and salvaged testicle groups. Times in patient management and clinical features were compared with Mann-Whitney, chi-squared, and Fisher exact tests. Multivariate logistical regression was used to identify independent factors associated with orchiectomy. RESULTS The median prehospital time of 48 h (15.4-138 h) in the orchiectomy group was longer than the 2.4 h (1.6 h-5.2h) in the salvaged group. Patients examined by a general practitioner (GP) prior to presenting at hospital had a median prehospital time of 48 h, compared to 3 h for patients not examined before presentation at hospital. In-hospital times between admission and operation room, as well as times between ultrasonography and operation room, were also longer in the orchiectomy group. Previous GP consultation (OR = 27.26, 95% CI 2.32-320.59, p = .009), prehospital time (OR = 1.04, 95% CI 1.01-1.07, p = .003) and nausea (OR = 9.25, 95% IC 1.33-64.52, p = .025) were independent predictive factors associated with orchiectomy. CONCLUSION Prehospital time was a determining factor in orchiectomy. For each extra hour of prehospital delay, the risk of orchiectomy increased by 4%. The rate of orchiectomy was higher among patients who first consulted a GP.

Abstract
Background: Neonatal scrotal hematoma is considered a surgical emergency in the neonatal period. Up to recently, immediate surgical exploration was considered the gold standard for the diagnosis and treatment in the underlying causes. Objective: In this article, we present a case of idiopathic scrotal hematoma in a neonate. Method: It was managed conservatively with clinical and ultrasonographic follow-up. Result: The hematoma had gradually subsided, and any surgical intervention was avoided to the neonate. Conclusion: With good clinical and imaging follow-up, some cases could be managed nonoperatively.

Abstract
INTRODUCTION Ultrasound is a valuable tool in establishing the cause of acute scrotum pain. However, its role in testicular torsion (TT) detection remains controversial. This review aims integrate pre-existing data to assess the value of B-mode and colour Doppler ultrasound (CDS) features combined in the detection of TT in acute scrotum pain patients of all ages. METHODS A search through electronic databases, grey literature and hand searching using specific search terms was conducted to identify relevant literature. Search results were subjected to a three-step selection process to ensure the inclusion criteria of this review were met. Statistical data pertaining to the accuracy, sensitivity, and specificity of the B-mode, CDS and combined B-mode CDS features were extracted. These results subsequently underwent a narrative analysis. RESULTS Five studies met the inclusion criteria. A variety of B-mode features were identified. Most studies showed that reliance on CDS alone can be prone to false-negative results. The combination of B-mode and CDS features were found to increase the overall sensitivity of ultrasound towards TT (up to 100% in 3 studies). All studies recommended correlation with clinical examination findings. Several limitations in methodology of the included studies were noted: small sample populations and lack of information on the experience of ultrasound practitioners. This highlighted the need for a primary study with a larger sample population to validate the findings of this review. CONCLUSION The combination of B-mode and CDS ultrasound is a useful and reliable triage tool in the detection of TT, particularly in equivocal or low suspicion cases but its findings should always be adjunct with clinical examination. Nevertheless, it is noted that appropriate service level agreements, pathways, and training are key factors in ensuring effectiveness of the process. IMPLICATIONS FOR PRACTICE Dedicated training and appropriate departmental protocol are key in ensuring accurate diagnosis across all levels of practice.

Abstract
Testicular torsion is a challenging and time-sensitive diagnosis that is encountered frequently in daily practice, especially in the emergency room. A thorough history, the presence of a painful and swollen testis and testicular ultrasonography plays a vital role in the prompt diagnosis of testicular torsion. Prompt diagnosis is essential to prevent complications of testicular torsion which include testicular infarction, necrosis, and sub/infertility. This can be challenging as there are various other conditions that may mimic the presentation of testicular torsion. Since testicular torsion is an extremely time-sensitive diagnosis, it may also be a subject of many medicolegal challenges. This review article serves as a guide for clinicians involved with the diagnosis and management of testicular torsion. We review and discuss detection and management strategies based on their validity, statistical significance, and effectiveness in enabling prompt diagnosis and management of testicular torsion. Medicolegal implications of testicular torsion are also highlighted.

Abstract
Acute scrotal pain is one of the most frequent symptoms in pediatric patients visited in the Emergency Department. Ultrasonography with color and power Doppler represents the first-line method that clinicians use to carry out the differential diagnosis between spermatic cord torsion and inflammation, but sensitivity and specificity are 63-100% and 97-100%, respectively; this variability may be related to operator's experience and testis vascular hemodynamics and also to machine performance and patient age. Recent technological innovations have made possible to create a new Doppler mode called ultrasound microvascular imaging. This technique exploits algorithms capable of separating low frequencies of static tissue artifacts from ones of very weak flows. It is known as MicroV (from Esaote) and Superb microvascular imaging (from Toshiba). It provides both macrocirculation vascular maps, as a typical Doppler feature, and microcirculation vascular maps. Furthermore, the use of background subtraction could improve the visibility of small vascular structures. We report a case of a pediatric patient suffering from acute scrotal pain assessed ultrasonographically with this innovative Doppler technique (MicroV) that may give more confidence in detecting testicular vascular signals if compared with traditional Doppler techniques.

Abstract
INTRODUCTION Acute scrotum is a common presentation to the pediatric emergency department, and ultrasound is frequently used to narrow the differential diagnosis. Point-of-care ultrasound (POCUS) is increasingly used by urologists and emergency physicians and could potentially be used to detect pediatric testicular torsion. OBJECTIVES This study aimed to determine the accuracy of POCUS by pediatric emergency physicians in diagnosing testicular torsion and the agreement between point-of-care ultrasound and final diagnosis for other causes of acute scrotum. STUDY DESIGN A chart review of patients presenting to the study emergency department who received POCUS by a pediatric emergency physician, as well as radiology department ultrasound and/or surgery, was performed. Charts were reviewed for POCUS diagnoses, final diagnoses, and imaging time metrics. RESULTS A total of 120 patients met study criteria, with 12 cases of testicular torsion. The diagnostic accuracy of POCUS for testicular torsion is described in the summary table. For all causes of acute scrotum, point-of-care ultrasound agreed with final diagnosis in 70% (95% confidence interval [CI] 62-78%) of cases, and more experienced point-of-care ultrasound users displayed higher agreement with final diagnosis. Point-of-care ultrasound results were generated a median of 73 min (Q1 = 51, Q3 = 112) before radiology department ultrasound results. DISCUSSION Scrotal POCUS performed by pediatric emergency physicians appears to be an accurate tool to detect testicular torsion in children with acute scrotum and saves time compared with radiology ultrasound. The study results may not be generalizable to hospitals without a multidisciplinary POCUS system for quality assurance and image sharing. Future work on POCUS for acute scrotum should investigate its impact on patient outcomes, cost-effectiveness, and family satisfaction. CONCLUSION Point-of-care ultrasound by pediatric emergency physicians is accurate for detecting testicular torsion in children with acute scrotum and could expedite diagnosis of this time-sensitive condition.

Abstract
Purpose Many physicians encounter confusion and difficulty in distinguishing testicular torsion (TT) from torsion of the appendix testis (TAT) in patients with acute scrotum because of the overlapping signs and symptoms. The objective of our study was to evaluate the clinical features and signs that can help distinguish TT from TAT. Patients and methods We performed a retrospective study of patients with surgically confirmed TT and TAT at our institute from January 1990 to December 2013. Clinical findings, physical examination findings, climatic conditions, laboratory data, and color Doppler ultrasound (CDUS) findings were compared between the TT and TAT groups. Results Seventy patients were included in this study (49 with TT and 21 with TAT). Patients with TT were significantly older than those with TAT (p < 0.001). The ambient temperature at onset was significantly lower in patients with TT than in patients with TAT (p = 0.038). Testicular swelling, high-riding testes, onset during sleep, high leukocyte counts, and high creatine phosphokinase levels were significantly more common in patients with TT than with TAT (p = 0.021, 0.032, 0.006, 0.003, and 0.043, respectively). Multivariate analysis showed that age and onset during sleep were significant independent factors for detection of TT. Eight patients (16.3%) underwent preoperative CDUS evaluation, and an absent or decreased blood signal in the involved testes was significantly correlated with the presence of TT (p = 0.018). Conclusion In clinical features, age and onset during sleep might be helpful to distinguish TT from TAT. When supported by findings, urgent surgical exploration is warranted in patients with suspected TT based on symptoms and CDUS features.

Abstract
Urogenital emergencies are fairly common in the pediatric population, and a timely and correct diagnosis is necessary to avoid possible future infertility. In this field, ultrasonography is essential, as it has the advantages of being radiation-free and readily accessible. In particular, a high-frequency transducer allows precise evaluation of the morphology and vascularity of the scrotum, which is on the surface of the body. Beyond conventional techniques, new advanced imaging techniques have been developed, including elastography and contrast-enhanced ultrasonography. However, several pitfalls remain in the diagnosis of urogenital diseases using ultrasonography. Thus, accurate knowledge and sufficient experience with the technique are essential for making a correct diagnosis. This review provides an overview of pediatric urogenital emergency pathologies and recent ultrasonography techniques.

Abstract
Pediatric blunt scrotal trauma is most often the consequence of sports injury and presents a diagnostic challenge because swelling and pain make a scrotal physical exam difficult. US with color flow and duplex Doppler is the first-line imaging modality with the goal of accurate and timely diagnosis of injury requiring surgery to preserve fertility and hormonal function. US imaging findings following blunt scrotal trauma include hydrocele, hematocele, testicular hematoma, testicular fracture, testicular rupture, compromised perfusion/testicular torsion and testicular dislocation. Importantly, several of these findings may coexist. Our goal is to present the pertinent intrascrotal anatomy, US imaging findings for each testicular injury, and contemporary management for each, with emphasis on what our pediatric urology colleagues need to know for optimal patient care.

BACKGROUND Besides physical examination, ultrasonography is the most valuable diagnostic tool to assess the scrotum and testes in the case of an acute scrotum or scrotal pathology. PROBLEMS In infants and toddlers the examination can be challenging. Due to the limited patient compliance, the small testicular size (< 0.5 ml), and low blood flow velocity (< 3 cm/s), it can be difficult to achieve a proper flow curve when assessing blood flow. CONCLUSION The examiner's skills are as important as adequate equipment (i. e., linear ultrasound probe, 12-14 MHz) and optimal program settings (Doppler scale < 3 cm/s, gate 1 mm). However, if there is doubt, surgical exploration is unavoidable.

Sonographic appearances of the epididymis in boys with acute testicular torsion but preserved testicular blood flow on color Doppler. Pediatr Radiol 2015; 45:1661-71. [PMID: 26104655 DOI: 10.1007/s00247-015-3375-z] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/29/2014] [Revised: 03/16/2015] [Accepted: 04/20/2015] [Indexed: 10/23/2022]
Abstract
BACKGROUND Little attention has been given to the sonographic appearances of the epididymis in testicular torsion. OBJECTIVE To describe the position and morphology of the epididymis in childhood acute testicular torsion when testicular flow is present on color Doppler sonography. MATERIALS AND METHODS We studied the sonographic findings in boys with clinically and surgically proven acute testicular torsion who were examined sonographically from May 2013 to May 2014 and who had preserved intratesticular flow on color Doppler sonography. We retrospectively evaluated the sonograms with emphasis on the epididymal findings. RESULTS In all nine boys with confirmed torsion but with preserved intratesticular flow on color Doppler sonography, the epididymal head had an unexpected configuration and size, and no close relationship with the upper pole of the testis. In five of these children the spermatic cord appeared twisted on the affected side. In the remaining four boys the spermatic cord appeared straight. CONCLUSION The position and morphology of the head of the epididymis were abnormal in all boys with acute testicular torsion but with preserved testicular flow.

Abstract
We investigated the appearances of intratesticular hematomas on multiparametric sonography combining grayscale, color Doppler, and contrast-enhanced sonography and strain elastography. Over a 3-year period, 17 hematomas in 8 patients were analyzed. Blunt trauma (n = 7) and surgery (n = 1) were preceding events. Grayscale sonography showed well-defined oval or round predominantly hypoechoic and heterogeneous, peripherally (n = 13) or centrally (n = 4) located lesions. Three showed contrast enhancement of septations, and 4 showed peripheral lesion rim enhancement. On strain elastography, the mean strain ratio was 1.19 (range, 0.41-2.36), and elasticity score were 3 or lower (n = 13) and 5 (n = 4). Multiparametric sonography shows nonenhancement with contrast and predominantly "soft" elastographic properties and aids in the interpretation of the benign nature of intratesticular hematomas.

Abstract
Neonatal scrotal hematoma is a rare genitourinary emergency. Some cases have underlining aetiologic factors such as testicular torsion, adrenal hemorrhage, or birth trauma, and others are idiopathic. Previously, immediate scrotal exploration was considered imperative for diagnosis and treatment. With good imaging techniques, some patients are managed nonoperatively. We report a case of idiopathic scrotal hematoma in a neonate. He was managed conservatively with clinical and radiological follow-up. There was complete resolution of hematoma within two months, thus, avoiding unnecessary exploration.

Abstract
To assess correlation between multi-planar, dynamic contrast-enhanced ultrasound (US) blood flow measurements and radiolabeled microsphere blood flow measurements, five groups of six rabbits underwent unilateral testicular torsion of 0°, 180°, 360°, 540° or 720°. Five US measurements per testis (three transverse/two longitudinal) were obtained pre-operatively and immediately and 4 and 8 h post-operatively using linear transducers (7-4 MHz/center frequency 4.5 MHz/10 rabbits; 9-3 MHz/center frequency 5.5 MHz/20 rabbits). Björck's linear least-squares method fit the rise phase of mean pixel intensity over a 7-s period for each time curve. Slope of fit and intervention/control US pixel intensity ratios were calculated. Means of transverse, longitudinal and combined transverse/longitudinal US ratios as a function of torsion degree were compared with radiolabeled microsphere ratios using Pearson's correlation coefficient, ρ. There was high correlation between the two sets of ratios (ρ ≥ 0.88, p ≤ 0.05), except for the transverse US ratio in the immediate post-operative period (ρ = 0.79, p = 0.11). These results hold promise for future clinical applications.

Abstract
OBJECTIVE The purpose of this study was to derive a pilot clinical decision tool with 100% negative predictive value for testicular torsion based on prospectively collected data in children with acute scrotal pain. METHODS This was a prospective cohort study of a convenience sample of newborn to 21-year-old males evaluated for acute (72 hours or less) scrotal pain at an urban children's hospital emergency department (ED). A pediatric emergency medicine fellow or attending physician documented history and examination findings on a standardized data collection form. The study investigators used ultrasound (US), operative reports, or clinical follow-up to identify patients who had testicular torsion. Pearson's chi-square test and odds ratios (OR) were used to identify factors associated with the diagnosis of testicular torsion. The authors also used a recursive partitioning model to create a low-risk decision tool for testicular torsion. RESULTS Of the 450 eligible patients, 228 (51%) were enrolled, with a mean (± SD) age of 9.9 (± 4.1) years, including 21 (9.2%, 95% confidence interval [CI] = 5.8% to 13.7%) with testicular torsion. The derived clinical decision tool consisted of three variables: horizontal or inguinal testicular lie (OR = 18.17, 95% CI = 6.2 to 53.2), nausea or vomiting (OR = 5.63, 95% CI = 2.08 to 15.22), and age 11 to 21 years (OR = 3.9, 95% CI = 1.27 to 11.97). These variables had a sensitivity of 100% (95% CI = 98% to 100%) and negative predictive value of 100% (95% CI = 98% to 100%) for the diagnosis of testicular torsion. CONCLUSIONS Based on a decision tool derived with recursive partitioning, study patients with all of the following characteristics had no risk of testicular torsion: normal testicular lie, lack of nausea or vomiting, and age 0 to 10 years. Future research should focus on externally validating this tool to optimize emergent evaluation when testicular torsion is likely, while minimizing routine sonographic evaluation when patients are unlikely to have a serious condition requiring immediate management.

Abstract
The evaluation and management of genitourinary emergencies is a fundamental component of the training and practice of emergency physicians. Urologic procedures are common in the emergency room. Emergency physicians play a vital role in the initial evaluation and treatment because delays in management can lead to permanent damage. This article discusses the most common urologic procedures in which emergency physicians must be proficient for rapid intervention to preserve function and avoid complications. An overview of each procedure is discussed as well as indications, contraindications, equipment, technique, and potential complications.

Abstract
Acute appendicitis presents typically with periumbilical pain that in a few hours settles at the right lower quadrant of the abdomen. Atypical presentations are common but association with acute scrotum is an extreme rarity. A 30-year-old fisherman presented at a rural medical facility with a 2-day complaint of severe pain at the right hemiscrotum followed about 24 hours later with mild diffuse abdominal pain. There was associated mild fever and nausea but no vomiting. There were no urinary symptoms and no recent sexual exposure. Initial physical examination revealed mild generalized tenderness worse at the right lower quadrant but the scrotum was not remarkable, and cremasteric sign was negative. He was admitted as a case of acute abdomen for close observation. Abdominal and scrotal ultrasound scan were normal. By the second day of admission, pain became marked at the right lower abdomen with associated vomiting. There was also marked tenderness at the right lower quadrant with rebound. A diagnosis of acute appendicitis was thus made and appendicectomy done after proper workup. The abdominal and scrotal pain stopped after surgery and the patient was discharged on the seventh postoperative day. Patients with unusual abdominal and scrotal pain should be admitted and closely observed and evaluated to prevent unnecessary scrotal exploration or negative appendicectomy.

Abstract
Contrast-enhanced ultrasound (US) imaging is potentially applicable to the clinical investigation of a wide variety of perfusion disorders. Quantitative analysis of perfusion is not widely performed, and is limited by the fact that data are acquired from a single tissue plane, a situation that is unlikely to accurately reflect global perfusion. Real-time perfusion information from a tissue volume in an experimental rabbit model of testicular torsion was obtained with a two-dimensional matrix phased array US transducer. Contrast-enhanced imaging was performed in 20 rabbits during intravenous infusion of the microbubble contrast agent Definity® before and after unilateral testicular torsion and contralateral orchiopexy. The degree of torsion was 0° in 4 (sham surgery), 180° in 4, 360° in 4, 540° in 4, and 720° in 4. An automated technique was developed to analyze the time history of US image intensity in experimental and control testes. Comparison of mean US intensity rate of change and of ratios between mean US intensity rate of change in experimental and control testes demonstrated good correlation with testicular perfusion and mean perfusion ratios obtained with radiolabeled microspheres, an accepted 'gold standard'. This method is of potential utility in the clinical evaluation of testicular and other organ perfusion.

Abstract
OBJECTIVE The aim of the study was to identify clinical findings associated with increased likelihood of testicular torsion (TT) in children. DESIGN This study used a retrospective case series of children with acute scrotum presenting to a pediatric emergency department (ED). RESULTS Five hundred twenty-three ED visits were analyzed. Mean patient age was 10 years 9 months. Seventeen (3.25%) patients had TT. Pain duration of less than 24 hours (odds ratio [OR], 6.66; 95% confidence interval [CI], 1.54-33.33), nausea and/or vomiting (OR, 8.87; 95% CI, 2.6-30.1), abnormal cremasteric reflex (OR, 27.77; 95% CI, 7.5-100), abdominal pain (OR, 3.19; 95% CI, 1.15-8.89), and high position of the testis (OR, 58.8; 95% CI, 19.2-166.6) were associated with increased likelihood of torsion. CONCLUSIONS Testicular torsion is uncommon among pediatric patients presenting to the ED with acute scrotum. Pain duration of less than 24 hours, nausea or vomiting, high position of the testicle, and abnormal cremasteric reflex are associated with higher likelihood of torsion.

Abstract
We present a quantitative near-IR spectroscopy study of the absolute values of oxygen saturation of hemoglobin before and after surgically induced testicular torsion in adult rabbits. Unilateral testicular torsions (0, 540, or 720 deg) on experimental testes and contralateral sham surgery on control testes are performed in four adult rabbits. A specially designed optical probe for measurements at multiple source-detector distances and a commercial frequency-domain tissue spectrometer are used to measure absolute values of testicular hemoglobin saturation. Our results show: (1) a consistent baseline absolute tissue hemoglobin saturation value of 78+/-5%, (2) a comparable tissue hemoglobin saturation of 77+/-6% after sham surgery, and (3) a significantly lower tissue hemoglobin saturation of 36+/-2% after 540- and 720-deg testicular torsion surgery. Our findings demonstrate the feasibility of performing frequency-domain, multidistance near-IR spectroscopy for absolute testicular oximetry in the assessment of testicular torsion. We conclude that near-IR spectroscopy has potential to serve as a clinical diagnostic and monitoring tool for the assessment of absolute testicular hemoglobin desaturation caused by torsion, with the possibility of serving as a complement to conventional color and spectral Doppler ultrasonography.

Abstract
The aim of the study was to compare historical features, physical examination findings, and testicular color Doppler ultrasound in pediatric patients with epididymitis compared to testicular torsion and torsion of the appendix testes. A retrospective review of the medical records of 66 boys presenting with clinical aspects of acute scrotum over a 3-year period was performed. Sixty-six patients were included in the study (29 with epididymitis, 8 with testicular torsion and 12 with torsion of the appendix testis, 4 with scrotal abscesses, 5 with scrotal swelling, and 1 with inflamed epididymal cyst). The duration of symptoms ranged from 6 h to 4 days with a peak on the second day. Urine cultures and viral testes were negative in all patients. Color Doppler ultrasound was diagnostic for epididymitis in 28 patients (96.6%). Systemic intravenous antibiotics were given in all 29 patients with epididymitis. No patient showed signs of testicular atrophy in the follow-up. The increasing incidence of epididymitis should question the policy of routine exploration of the acute scrotum in children. The history and physical examination cannot reliably identify those boys who can be managed conservatively. Color Doppler ultrasound is a useful adjunct in the evaluation of the acute scrotum when physical findings are equivocal but it can also be misleading.

Abstract
Intratesticular haematoma is not well described in the ultrasound literature and may be mistaken for a primary testicular malignancy if a detailed clinical history and careful ultrasound examination are not performed. We report two cases of intratesticular haematoma (one complicated by the presence of microlithiasis), describe the ultrasound appearances and document the natural history of the haematomas. A clinical history coupled with Doppler ultrasound features is crucial for conservative management.

Abstract
The purpose of this study was to assess the clinical presentation and ultrasonographic findings of acute scrotum in young males. A total of 87 patients (<or= 25 years old) with presentation of acute scrotum were retrospectively analyzed in Kaohsiung Medical University Hospital. The patients were divided into three groups according to their final diagnosis: 41 patients with testicular torsion (TT), eight patients with torsion of the testicular appendage (TTA), and 38 patients with epididymo-orchitis (EO). The mean ages of the TT group (14.0 +/- 5.7 years) and EO group (16.6 +/- 7.6 years) were higher than that of the TTA group (10.0 +/- 3.5 years) (p = 0.02). White blood cell count (> 10,000 cells/microL) was not found to be statistically different among groups. Pyuria was found in 10 (26%) patients with EO. Color Doppler ultrasound has high sensitivity (87.9%) and specificity (93.3%) rates to differentiate TT from other causes of acute scrotum. In cases with a lower risk of TT, we suggest that a technically adequate color Doppler ultrasound may be arranged to help differentiate diagnoses and prevent needless surgery. The importance of emergent management for acute scrotum should also be impressed upon the public through education to avoid delayed presentation to medical facilities.

Abstract
Pediatric surgeons and urologists are often asked to evaluate boys with acute scrotal pain and inflammation. Although there are myriad etiologies for this syndrome, testicular torsion should be at the top of the list. It is the one diagnosis that must be made accurately and rapidly if there is any hope for testicular salvage. The purpose of this article is to update/review the appropriate evaluation and management of the acute scrotum and to guide the clinician in distinguishing testicular torsion from the other conditions that commonly mimic this surgical emergency.

Abstract
PURPOSE Intravaginal or extravaginal spermatic cord torsion is a diagnostic challenge for the surgeon and radiologist. Color Doppler sonography can be inaccurate, leading to dangerous false-negative results. To date, no single reliable test has been able to provide 100% diagnostic accuracy. The direct visualization of the twisted cord during emergency high resolution ultrasonography has been proposed to avoid systematic and abusive surgical exploration. The aim of this multicenter study was to assess the validity and reproducibility of high resolution ultrasonography based management of acute scrotum in children. MATERIALS AND METHODS A total of 919 patients from 11 European university hospitals underwent color Doppler sonography and high resolution ultrasonography for acute scrotum between 1992 and 2005. The spermatic cord was studied along its complete length to detect a spiral twist. The surgical findings were correlated with the preoperative results. RESULTS A total of 208 patients had spermatic cord torsion proved at surgery. Intratesticular vascularization was absent in the affected testis in only 158 cases (76%). In contrast, high resolution ultrasonography detected the twist as a snail shell-shaped mass, measuring 7 to 33 mm, in 199 patients (96%). High resolution ultrasonography revealed a linear cord for all other causes of acute scrotum (711 patients) with a specificity of 99%. The radiologist training level was the best predictive factor of high resolution ultrasonography reliability (p <0.05). CONCLUSIONS High resolution ultrasonography based management of acute scrotum is reliable and reproducible. Thanks to its high sensitivity and specificity for the diagnosis of spermatic cord torsion, high resolution ultrasonography can significantly improve the management of acute scrotum in children.

Abstract
INTRODUCTION AND OBJECTIVES Our experience concerning the use of color Doppler sonography (CDS) in the differential diagnosis of acute scrotum is reported. MATERIAL AND METHODS From July 2000 to July 2005, 155 patients (median 17.2 years) were admitted with a diagnosis of acute scrotum (unilateral in 150 cases, bilateral in 5). Along with a careful anamnesis and the physical exam, all patients underwent a CDS study of the scrotal content using a sonograph GE Logiq 500 with a multifrequency (7.5-10 MHz) linear probe Small Part. The following CDS parameters were evaluated: intensity of the color-power signal on the testicular parenchyma and on the epididymis; systolic peak velocity (SPV) and telediastolic velocity (TDV) in correspondence of the gonadal hilum. Ultrasound and flowmetry parameters registered on the painful testis were compared with those registered on the healthy controlateral testis. The reduction/absence versus the increase of color-power signal in the parenchyma and the reduction/absence versus the increase of SPV and TDV in the centripetal intratesticular arteries were considered presumptive of testicular torsion versus orchiepididymitis. RESULTS The results only refer to the 150 patients (300 testis) with acute monolateral scrotum. The clinical picture and the physical exam suggested a torsion of the spermatic cord in 40 cases, a spontaneous de-torsion in 5, an orchiepididymitis in 80, a blunt scrotal trauma in 15, a bulky epididymal cyst or a hydrocele in 4 and a testicular pain of unknown etiology in the remaining 6 cases. Standard US was pathological in 95 patients (63.3%); CDS was pathologic in 70 patients and in 42 of them suggested a testicular torsion. Fifty-three patients underwent surgical exploration: among 42 patients with a presumptive diagnosis of testicular torsion, the diagnosis was confirmed in 22 cases, no anomaly was found in 16 cases and in 4 patients a torsion of testicular appendix was found. The rupture of the tunica albuginea was present in six out of seven patients submitted to surgical exploration for previous blunt trauma and the sonographic diagnosis of hematocele was documented in all cases. The single false-negative diagnosis of testicular torsion in CDS occurred in an 18-month-old child. In presence of funicular torsion, the sensitivity and specificity of physical exam and CDS were 100% versus 95.7% and 86.5% versus 85.3%, respectively; sensitivity and specificity of SPV, TDV and color-Doppler signal on the testis were 100% and 94.8% versus 100% and 90.1% versus 95.7% and 90.8%. In the pre-operative assessment of scrotal trauma, the B-mode US showed a sensitivity and specificity of 100% and 90%, respectively; the color Doppler analysis has not supplied with additional elements for planning a surgical exploration. In presence of orchiepididymitis, the sensitivity and specificity of the physical exam in association to CDS was equal to 100%. In all patients with torsion of the testicular appendix, physical exam and CDS parameters were within normal limits. DISCUSSION AND CONCLUSIONS In our experience CDS is an indispensable imaging modality for the clinical assessment of patients with acute scrotum; however, the informations it can afford are operator-dependent and have to be supported by the history and physical exam of the patient. CDS findings constitute probably an important medico-legal support when the necessity of surgical exploration is excluded; anyway, in presence of a clinical suspicion of testicular torsion, even with an apparently normal CDS, the surgical exploration is recommended.

Abstract
Contrast-enhanced ultrasound (US) imaging is potentially applicable to the investigation of vascular disorders of the testis. We investigated the ability of two automated computer algorithms to analyse contrast-enhanced pulse inversion US data in a rabbit model of unilateral testicular ischaemia and to correctly determine relative testicular perfusion: nonlinear curve fitting of the US backscatter intensity as a function of time; and spectral analysis of the intensity time trace. We compared (i) five metrics based on the algorithmic data to testicular perfusion ratios obtained with radiolabelled microspheres, a reference standard; (ii) qualitative assessment of the US images by two independent readers blinded to the side of the experimental and control testes to the radiolabelled microsphere perfusion ratios; and (iii) results of the algorithmically-derived metrics to the qualitative assessments of the two readers. For the curve fit method, the algorithmically-derived metrics agreed with the reference standard in 54% to 68% of all cases. For the spectral method, the results agreed in 70% of all cases. The two readers agreed with the reference standard in 40% and 35% of all cases, respectively. These results suggest that automated methods of analysis may provide useful information in the assessment of testicular perfusion.

Abstract
BACKGROUND AND PURPOSE Torsion of the testicular appendages (TTA) is the most common cause of acute scrotum in children, and yet there are only few dedicated studies of the imaging findings. OBJECTIVE To review our experience with the use of duplex sonography in children with TTA and to evaluate if sonography can successfully distinguish TTA from epididymoorchitis. METHODS We reviewed the medical files and imaging findings of 29 children aged 0.7 to 13.9 years (mean, 6.5 years) with a diagnosis of TTA based on testicular exploration who were evaluated preoperatively with duplex sonography. RESULTS A tender upper pole nodule, the typical sign of TTA, was palpated in only 2 (6.9%) children. Duplex sonography demonstrated an extratesticular upper pole nodule in 9 (31%) children. Secondary inflammatory changes included hydrocele in 22 (75.9%), enlarged epididymis in 22 (75.9%), scrotal wall edema in 16 (55.2%), and swollen testis in 9 (31%) children. Fourteen (48%) children had inflammatory changes with no evidence of an extratesticular nodule. CONCLUSION Duplex sonography findings of secondary inflammatory changes in the absence of evidence of an extratesticular nodule may suggest an erroneous diagnosis of epididymitis or epididymoorchitis in children with TTA.
