The challenges in diagnosing isolated epididymal tuberculosis (TB) in an adolescent male: a case report.

BACKGROUND: Genitourinary tuberculosis (GUTB) is a common form of extrapulmonary TB (EPTB) in children. An example of GUTB is epididymal TB, which usually presents unspecific chronic clinical manifestations. Definitive diagnosis can be conducted based on bacteriologic confirmation and histopathologic results, but this is challenging due to the paucibacillary nature of EPTB. Therefore, we reported the challenges in diagnosing isolated epididymal TB in an adolescent male. CASE PRESENTATION: A 16-year-old male presented to respirology clinic with painful swelling of the left scrotum for 3 months before visiting to the hospital. The symptoms were associated with persistent coughing for 2 months, and physical examination of the left scrotum showed swelling accompanied by cardinal signs. A palpable hard mass was found on the left scrotum, with firm borders, measuring 7 × 4 cm. Laboratory examination and tumor markers were within normal limits, although leukocyturia was found, and the urine culture was negative. Genital ultrasound (US) showed epididymitis sinistra with septal hydrocele, while magnetic resonance imaging (MRI) indicated inhomogeneous left epididymitis with bilateral inguinal lymph node enlargement. Although TB evaluation presented a negative purified protein derivative (PPD) test and bacteriologic examination, chest X-ray (CXR) showed perihilar lymphadenopathy. Based on the clinical and radiologic results suggesting TB, the patient was diagnosed with isolated epididymal TB and received quadruple antituberculosis therapy (ATT) for 6 months. After treatment, the left testicle size started to shrink and was equal to the right testicle, also, there were no signs of inflammation, the body weight increased by 5 kg, and cough disappeared. Sperm analysis at the end of treatment indicated teratozoospermia, which was subsequently treated by the urologic surgery department. CONCLUSIONS: Biopsy and bacteriologic confirmation for TB epididymitis were challenging to perform in the clinical setting. Epididymal TB should be considered in adolescent males with complaints of chronic scrotal swelling and pain. Clinical judgment based on history taking, physical examination, and radiologic features supporting TB features could be helpful in accurate and fast diagnosis for favorable outcome.

Paediatric acute epididymo-orchitis temporally related to SARS-CoV-2 infection: A case series and review of the literature.

INTRODUCTION: Acute epididymo-orchitis (AEO) is becoming an increasingly common differential diagnosis in children with acute scrotal pain. It has been noted in adult men that SARS-CoV-2 has a propensity for involving the testis and epididymis, affecting sperm and testosterone production. Our literature search revealed only one case report of COVID-19 presenting with epididymo-orchitis in a child. We present three more children who presented with AEO, all recovering from PCR-confirmed SARS-CoV-2 infection. This article reviews the post-inflammatory aetiology of paediatric epididymo-orchitis, and the propensity SARS-CoV-2 has for the testis. PATIENTS AND METHODS: Two pre-pubertal ten-year-old patients presented to the emergency department with a 48-h history of gradual onset unilateral scrotal pain and increasing erythema of the ipsilateral scrotal skin. One fifteen-year-old boy was referred for ongoing symptoms four days following a diagnosis of AEO made by his General Practitioner. On further questioning, all three had PCR-confirmed COVID infection two weeks prior to the onset of their scrotal symptoms and had just ended their isolation period. A literature search was then performed using the keywords SARS-CoV-2, testes and paediatric acute epididymo-orchitis. DISCUSSION: The SARS-Cov-2 virus has a propensity for affecting the testis and epididymis. This puts patients at increased risk of acute epididymo-orchitis during COVID infections. The inflammation induced by the virus appears to affect the cells responsible for testosterone production and sperm quality. However, there is no evidence that viral transmission can happen via semen. CONCLUSION: SARS-Cov-2 infection can lead to acute epididymo-orchitis. Knowledge of this is clinically significant, firstly to avoid unnecessary surgical intervention due to a mistaken diagnosis of testicular torsion and secondly, due to the potential of the virus to affect sperm quality and testosterone production.

Acute cytomegalovirus proctitis and epididymitis acquired via sexual transmission in an immunocompetent patient: a case report.

BACKGROUND: We present a case report of an immunocompetent host with presumed sexually transmitted cytomegalovirus proctitis and epididymitis, where there currently is a sparsity of published data. CASE PRESENTATION: A 21-year-old previously healthy Caucasian individual was admitted for severe rectal and testicular pain in the setting of proctitis and epididymitis. Serology and rectal pathology confirmed acute primary cytomegalovirus infection. CONCLUSIONS: This report details his diagnostic workup and highlights cytomegalovirus as a rare cause of sexually transmitted disease among immunocompetent persons.

Testicular involvement of Brucellosis: A 10-year, multicentre study.

INTRODUCTION: The genito-urinary system is one of the most common areas of involvement in brucellosis. To present the epidemiological, clinical, and laboratory characteristics of patients with testicular involvement associated with brucellosis, together with the diagnostic and therapeutic approaches. METHODOLOGY: Patients followed up for brucellosis-related testicular involvement between January 2012 and November 2022 were included in the study. Brucellosis is defined as the production of Brucella spp. in cultures, or clinical symptoms together with the serum standard tube agglutination test titer of ≥ 1/160. Inflammation in scrotal Doppler ultrasonography was based on testicular involvement. RESULTS: A retrospective evaluation was made of the data of 194 patients with brucellosis-related testicular involvement. The rate of determination of testicular involvement in brucellosis was 2.57%. The most affected patients were determined in the 16-30 years age range. On presentation, brucellosis was in the acute stage in 83.7% of patients. The most common symptoms on presentation were swelling and/or pain in the testes (86.6%). In the patients where a spermiogram could be performed, oligospermia was determined in 41.7%, and aspermia in 8.3%. When the testicular involvement of brucellosis was evaluated, epididymo-orchitis was present at the rate of 55.7%, epididymitis at 27.3%, and testis abscess at 5.1%. CONCLUSIONS: Although epididymo-orchitis was the most frequently determined form of involvement in this study, there was also seen to be a significant number of patients presenting with epididymitis. Male patients presented with the clinical status of brucellosis should be questioned about swelling and pain in the testes to avoid overlooking testicular involvement.

Escroto agudo en el lactante / Acute scrotum in infants

El escroto agudo consiste en un cuadro clínico de dolor testicular asociado a signos inflamatorios locales, excepcional en neonatos y lactantes. Presentamos un caso de un lactante de 2 meses con tumefacción y eritema escrotal derecho de 48 horas de evolución y pico febril en Urgencias. A la exploración, teste doloroso a la palpación, con reflejo cremastérico presente. En la ecografía testicular se objetiva orquiepididimitis derecha. La analítica muestra leucocitosis, neutrofilia y mínima elevación de reactantes de fase aguda. En el urocultivo se aísla Escherichia coli. Recibe antibioterapia durante 2 semanas con buena evolución. La orquiepididimitis es la inflamación aguda del testículo y epidídimo, patología muy infrecuente en neonatos y lactantes. La diseminación hematógena es la causa más frecuente en este grupo de edad, siendo el germen más frecuente el E. coli. Por tanto, en neonatos y lactantes con orquiepididimitis, considerando el riesgo de bacteriemia asociada, resulta fundamental optimizar el diagnóstico, incluyendo un estudio completo de sepsis junto con la ecografía Doppler y el inicio precoz de la antibioterapia empírica (AU)

Acute scrotum consists of testicular pain associated with local inflammatory signs and is very unsual in neonates and infants.We present a case of a 2-month-old infant with right scrotal swelling and erythema of 48 hours' evolution. Peak fever in the emergency department. On examination, the teste was painful on palpation, with cremasteric reflex present. Testicular ultrasound showed right orchiepididymitis with associated hydrocele. Laboratory tests show leukocytosis, neutrophilia and minimal elevation of acute phase reactants. Urine culture isolated Escherichia coli. He received antibiotherapy for 2 weeks with good evolution.Orchiepididymitis is an acute inflammation of the testicle and epididymis, and it is a very rare pathology in neonates and infants. Haematogenous dissemination is the most frequent cause in this age group, with E. coli being the most frequently isolated germ. Therefore, in neonates and infants with orchiepididymitis, considering the risk of associated bacteraemia, it is essential to optimize the diagnosis by including a complete sepsis study together with Doppler ultrasound and the early initiation of empirical antibiotherapy.

Outcome of acute epididymo-orchitis: risk factors for testicular loss.

PURPOSE: Acute epididymo-orchitis (AEO) is a common urological condition characterised by pain and swelling of the epididymis which can affect men of any age. The aetiology and to some extent the management of the patient differ between paediatric and young and older adult groups. METHODS: A retrospective analysis was performed at the University Hospital Limerick from 2012 to 2016. Hospital In-Patient Enquiry (HIPE) data were obtained for all patients diagnosed with orchitis, epididymitis, epididymo-orchitis or testicular abscess over this 5-year period. RESULTS: 140 patients were identified, the age range was 0-89, median age 35.6. These were then split into 3 clinical groups, pre-pubertal (Group 1, 0-15-year-olds), sexually active young men (Group 2a, 16-35-year-olds) and men over 35 (Group 2b). Nine patients had an abscess on ultrasound investigation. There was a significant correlation between the presence of an abscess and the need for an orchidectomy (2 patients, P = 0.035). Two patients were reported as having an atrophic testis following AEO and both were in Group 2b. CONCLUSION: Overall, 7/131 (5%) patients had loss or atrophy of a testicle following an episode of AEO. Nineteen patients had further readmissions with AEO (14%).

Testicular ischemia secondary to acute epididymitis: A case report.

RATIONALE: Rare side effects of acute epididymitis include testicular infarction and ischemia. Distinguishing them from testicular torsion is challenging, both clinically and radiologically. However, only a few such cases have been reported to date. PATIENT CONCERNS: A 12-year-old child presented with persistent right testicular pain for 3 days. It developed after trauma and was accompanied by gradual swelling and enlargement of the right scrotum, with nausea and vomiting. Scrotal color Doppler ultrasonography demonstrated right epididymitis, right scrotal wall swelling, and right testicular torsion. Routine blood tests revealed leukocyte and neutrophil counts were both above normal. DIAGNOSIS: Scrotal exploration revealed edema and adhesions in all layers of the scrotal wall. The right testicle was pale. The patient was diagnosed with testicular ischemia secondary to acute epididymitis. INTERVENTIONS: The patient underwent simultaneous lower spermatic cord sheath dissection and decompression, testicular sheath reversal, and right testicular fixation. OUTCOMES: Blood flow to the testicles gradually recovered after decompression, as did the color. Postoperatively, the patient's scrotal swelling and pain improved significantly. LESSONS: Despite the rarity of this condition, it is a potentially serious consequence of epididymitis and should be considered when patients experience sudden scrotal pain.

Epididymo-orchitis Presenting as Bilateral Hydrocele in a Young Adult.

We present a case of young patient who presented with a progressive scrotal swelling and low-grade fever. An ultrasound of the scrotum revealed multiple small well-defined hypoechoic lesions in both testes with bulky epididymis and bilateral hydrocele. The final diagnosis was confirmed on cytology. The typical imaging findings may help to reach the diagnosis and to plan the further management in such cases.

Possible case of polyarteritis nodosa with epididymitis following COVID-19 vaccination: A case report and review of the literature.

The global outbreak of coronavirus disease (COVID-19) caused by severe acute respiratory syndrome coronavirus type 2 has prompted the rapid spread and development of vaccines to prevent the spread of the disease. COVID-19 vaccine has demonstrated excellent efficacy in reducing morbidity and severity of the disease, and most adverse reactions are very minor. However, some patients have been reported to develop autoimmune diseases, such as rheumatoid arthritis, myocarditis, Guillain-Barre syndrome, and vasculitis, following COVID-19 vaccination. Herein, we present a case of polyarteritis nodosa with epididymitis, following COVID-19 mRNA vaccination. The patient's initial symptoms were fever and testicular pain, and magnetic resonance imaging showed epididymitis. He was diagnosed as having polyarteritis nodosa with epididymitis and was treated with high-dose prednisolone, with a good clinical outcome.

Diagnostic nomogram to differentiate between epididymal tuberculosis and bacterial epididymitis.

PURPOSE: We developed and validated a diagnostic nomogram for differentiating epididymal tuberculosis (TB) from bacterial epididymitis. METHODS: In this retrospective study, we developed a prediction model based on demographics and clinical characteristics. Eligible patients were randomly divided into derivation and validation cohorts (ratio 7:3). Univariate and multivariate regression analyses were used to filter variables and select predictors. Multivariate logistic regression was used to construct the nomogram. Concordance index (C-index), calibration plots, and decision curves analysis (DCA) were used to assess the discrimination, calibration, and clinical usefulness of the nomogram. RESULTS: We included 147 patients (epididymal TB, 93; bacterial epididymitis, 54). The derivation cohort included 66 patients with epididymal TB and 38 with bacterial epididymitis; the validation cohort included 27 patients with epididymal TB and 16 with bacterial epididymitis. One regression model was built from three differential variables: body mass index, purified protein derivative, and chronic infection. Accordingly, one nomogram was developed. The model had good discrimination and calibration. C-indexes of the derivation and validation cohorts were 0.89 and 0.98 (95% confidence intervals, 0.83-0.95 and 0.94-1.01), respectively. DCA showed that the proposed nomogram was useful for differentiation. CONCLUSION: The nomogram can differentiate between epididymal TB and bacterial epididymitis.

The challenging diagnosis of acute scrotum: remaining difficulties and further insights.

The main target during management of a male pediatric patient with clinical signs of acute scrotum is the timely diagnosis, in order not to jeopardize the viability of the affected testicle. Thorough evaluation of the patient's medical history, symptomatology, clinical and ultrasonographic findings, constitutes the basis of the diagnostic procedure. After comprehensive research of the relevant literature, we highlight the remaining difficulties in the evaluation of the clinical and ultrasonographic findings for the accurate diagnosis of the acute scrotum. In conclusion, it is worth emphasizing on the following: a. the most common diseases that come under the diagnosis of the acute scrotum may present with similar symptoms, b. in neglected cases the diagnostic approach becomes more difficult, constituting the evaluation of the pathognomonic clinical signs challenging, and c. inability to exclude the diagnosis of spermatic cord torsion should be an indication for the surgical exploration of the affected hemiscrotum.

Scrotal Masses.

Scrotal and testicular masses can be broadly categorized into painful conditions, which include testicular torsion, torsion of the testicular appendage, and epididymitis, and painless conditions, which include hydrocele, varicocele, and testicular cancer. Testicular torsion is a urologic emergency requiring prompt surgical intervention to save the testicle, ideally within six hours of presentation when the salvage rate is about 90%. The Testicular Workup for Ischemia and Suspected Torsion score can be used to help physicians identify patients at high risk of torsion and those at lower risk who would benefit from imaging first. Torsion of the testicular appendage presents with gradual onset of superior unilateral pain, is diagnosed using ultrasonography, and is treated supportively with analgesics. Epididymitis is usually caused by infection with Chlamydia trachomatis, Neisseria gonorrhoeae, or enteric bacteria and is treated with antibiotics, analgesics, and scrotal support. Hydroceles are generally asymptomatic and are managed supportively. Varicoceles are also generally asymptomatic but may be associated with reduced fertility. It is uncertain if surgical or radiologic treatment of varicoceles in subfertile men improves the rate of live births. Testicular cancer often presents as a unilateral, painless mass discovered incidentally. Ultrasonography is used to evaluate any suspicious masses, and surgical treatment is recommended for suspected cancerous masses.

Incidental Tuberculosis Epididymitis/Epididymo-orchitis: A Retrospective Analysis at a Tertiary Center in Taiwan.

OBJECTIVES: To determine the earliest noticeable manifestation and diagnosis in patients diagnosed with tuberculosis (TB) epididymitis/epididymo-orchitis incidentally and to analyze their responses to surgical and medical treatment. METHODS: Patients who underwent surgery for the preliminary impression of chronic epididymitis/epididymo-orchitis or epididymal/testicular tumor from 2000 to 2019 were included in the study. The clinical presentations, laboratory data, radiological examinations, and operative findings were analyzed retrospectively. The outcomes were assessed by the responses to anti-TB chemotherapy and post treatment radiographic evaluations. RESULTS: All of our 25 patients with a mean age of 60.6 years were diagnosed incidentally with TB epididymitis (48.0%) and TB epididymo-orchitis (52.0%) according to the histopathological findings from their surgeries. The presence of a palpable scrotal mass (76.0%), was the major presentation. Nineteen (76.0%) patients had undergone complete chemotherapy after the surgery and 15 (78.9%) patients showed complete recovery. Four (21.1%) patients had unfavorable outcomes, 3 had TB autonephrectomies and 1 required re-surgery years after complete chemotherapy. Of the 3 (12.0%) patients who did not receive chemotherapy after their surgeries, 1 had a TB relapse in the spine and lung and 1 developed bladder cancer years later. CONCLUSION: Tuberculosis epididymitis/epididymo-orchitis is difficult to diagnose. However, some clinical clues can assist including aged patients, extragenital TB histories, poor responses to antibiotic treatment and scrotal skin lesion. Complete anti-TB chemotherapy is mandatory even after the total removal of TB lesion. Supplemental surgical interventions can be considered when the symptoms are not relieved after chemotherapy. Lifespan follow-up is recommended due to high relapse rate.

Advances in the antibiotic management of epididymitis.

INTRODUCTION: Acute epididymitis is commonly encountered and typically presents acutely within a wide clinical spectrum. Most cases of acute epididymitis are caused by bacterial infection, most often by sexually transmitted organisms and urinary pathogens. Current treatment regimens remain empirical, although recent advances using modern diagnostic techniques support a change in the management paradigm. AREAS COVERED: The choice of the initial antibiotic regimen is empirical and based on the most likely causative pathogen, whether sexually transmitted, enteric, or other. Adherence of clinical practice remains short of available guidance, which may be improved by thorough clinical and microbiologic assessment, supported by a knowledge of the commonly associated pathogenic organisms, and the appropriate choice of tests required for their identification. The use of advanced microbiology techniques and studies of current practice provide new insights that have challenged traditional management paradigms. The authors discuss these points and provide their expert perspectives on its treatment and future developments. EXPERT OPINION: Relatively sparse direct trial data exists on antimicrobial treatments for acute epididymitis. Much of the presently available guidance is derived from previous guidance recommendations, knowledge of antimicrobial activities of specific agents, and treatment outcomes in uncomplicated infections. Identification of specific pathogens and prescribing accuracy is dependent on the extent to which cases are investigated and is therefore variable.

Epstein-Barr virus-associated infectious mononucleosis with acute epididymitis: a case report.

BACKGROUND: Infectious mononucleosis due to the Epstein-Barr virus is an infectious disease that causes the appearance of atypical lymphocytes in the peripheral blood; it mainly presents with fever, tonsillar pharyngitis, and lymphadenopathy. In addition to hepatitis, splenomegaly, and rashes, it can involve different organs. Here, a case of epididymitis as a rare complication in a patient with Epstein-Barr virus-associated infectious mononucleosis was reported. CASE PRESENTATION: A healthy 23-year-old man visited an outpatient clinic with fever and pharyngitis. Tonsillar pharyngitis, lymphadenopathy, atypical lymphocytes in the peripheral blood, liver dysfunction, and splenomegaly were observed. The patient was diagnosed with infectious mononucleosis based on clinical signs. The next day, the patient developed left testicular pain and was immediately transferred to the emergency outpatient ward. Pain, redness, and swelling were observed in the left scrotum. Ultrasonography revealed swelling of the epididymis and increased blood flow, and the patient was hospitalized with a diagnosis of left epididymitis. The patient's symptoms improved with symptomatic treatment and was discharged on day 16 after admission. Changes in antibody titers established a definitive diagnosis of infectious mononucleosis caused by the Epstein-Barr virus. Based on the disease course, the patient was also diagnosed with infectious mononucleosis associated with unilateral epididymitis. CONCLUSIONS: This is the first case report of Epstein-Barr virus-associated infectious mononucleosis complicated with acute epididymitis. Infectious mononucleosis can cause numerous organ-related complications; thus, physicians and healthcare workers should remain cognizant of Epstein-Barr virus-associated complications throughout the body and not just in the primary organs affected by infectious mononucleosis.

Urological Impact of Epididymo-orchitis in Patients with Anorectal Malformation: An ARM-Net Consortium Study.

INTRODUCTION: To investigate the current experience of the ARM-Net Consortium in the management of epididymo-orchitis (EO) in patients with anorectal malformations (ARMs), and to identify specific risk factors and the need for urological care involvement. MATERIALS AND METHODS: We retrospectively collected data of EO in patients with ARM between 2015 and 2019. Data on urological aspects, ARM type, surgical approach, associated anomalies, diagnosis, and treatment of EO were collected and analyzed. RESULTS: Twenty-nine patients were reported by 12 centers. Twenty-six patients with EO (90%) had ARM with a rectourinary fistula. Median age at first EO was 2 years (range: 15 days-27 years). Twenty patients (69%) experienced multiple EO, and 60% of recurrences were ipsilateral. Associated urological anomalies included vesicoureteral reflux (48%), urethral anomalies (41%), neurogenic bladder (41%), and ectopic vas (10%). A positive urine culture during EO was present in 69%. EO was treated with antibiotics (90%), limiting surgical exploration to 14%. Prevention of recurrences included surgery (bulking agents 15%, vasectomy 15%, and orchiectomy 5%) and antibiotic prophylaxis (20%). CONCLUSION: Urologists may encounter patients with EO in ARM patients, frequently with positive urine culture. An appropriate urologic work-up for most ARM patients is necessary to identify and treat underlying risk factors. A practical scheme for the work-up is suggested for a close collaboration between pediatric surgeons and urologists.

Testicular appendage torsion in children.

BACKGROUND: Testicular appendage torsion (TAT) is a medical emergency that presents as an acute scrotum, usually in children and preadolescents. In previous reports of TAT, most cases have been treated conservatively, but some necessitate surgical treatment. Our aim was to examine the incidence, clinical examination findings, etiology, and treatment of TAT. METHODS: We retrospectively reviewed records of all patients with TAT (aged ≤15 years) treated at the Juntendo University Urayasu Hospital between January 2012 and September 2020. Surgical treatment was performed when a diagnosis of testicular torsion could not be completely ruled out or if pain recurred after conservative treatment. Patients with a hard scrotum or scrotal erythema were hospitalized for conservative treatment. Data regarding age, diagnosis, blood test results, and clinical findings were analyzed. RESULTS: Among 101 boys with TAT, the median age was 10 years. The incidence of TAT varied significantly according to age and was highest among patients aged 8-11 years. Sixty-seven boys (66.3%) underwent inpatient surgical treatment, 10 boys (9.9%) received inpatient conservative treatment, and 24 boys (23.8%) received outpatient conservative treatment. The median duration of hospitalization was significantly shorter among those who underwent surgery (2.0 days) than among those who received inpatient conservative treatment group (3.5 days). CONCLUSIONS: Operations were short, uncomplicated, and safe; they shortened the hospital stay; and they would certainly prevent recurrence of TAT and testicular torsion on one side. Furthermore, we recommended that TAT patients presenting with signs of severe inflammation, such as hard scrotum or scrotal erythema, receive early surgical treatment to minimize duration of hospitalization.
