OBJECTIVE
To evaluate the effect of a new strategy of transperineal anastomotic urethroplasty (TAU) with proximal transection in treating pelvic fracture urethral injury (PFUI) associated with urethrorectal fistula (URF).
PATIENTS AND METHODS
A retrospective review of all patients treated by TAU with proximal transection and fistula repair for PFUI associated with URF was performed between August 2013 and July 2022. Information on demographics, peri-operative variables, and postoperative follow-up outcomes was collected. Successful surgery was defined as restoration of a uniform urethral calibre using flexible cystoscopy (third postoperative month) without strictures or leakage, with no further interventions required. Functional outcomes, including erectile function (assessed using the five-item International Index of Erectile Function) and urinary continence, were assessed.
RESULTS
Forty patients diagnosed with PFUI associated with URF and treated by TAU with proximal transection and rectal fistula repair were enrolled. Six patients (15.0%) had a history of failed urethral reconstruction. The mean stenosis length and fistula diameter were 2.9 cm and 1.2 cm, respectively. All patients underwent faecal diversion before urethroplasty. After a median (range) follow-up of 45 (3-115) months, the final success rate was 90.0% (36/40). Postoperative complications included haematoma in three patients, epididymo-orchitis in three, wound infection in one, wound bleeding in one, delayed wound healing in three, and wound numbness in three. The overall incidence of postoperative erectile dysfunction reached 75.0%, with a median (range) score of 9 (0-19). Normal continence was achieved in 31 patients (77.5%). Occasional incontinence without the need for urinal pads occurred in eight patients, whereas one patient required urinal pads.
CONCLUSIONS
Transperineal anastomotic urethroplasty with proximal transection is a precise and effective surgical strategy for treating PFUI associated with URF. This strategy ensures a high success rate and improves surgical efficiency.

Behçet's disease is a chronic systemic inflammatory vasculitis of unknown etiology. It is characterized by recurrent episodes of oral aphthous ulcers, genital ulcers, skin lesions, ocular lesions, and other manifestations. This disease affects many organs and systems, showing a wide range of clinical features. Although pulmonary artery involvement is not common in Behçet's disease, its presence carries a substantial risk of mortality. This report provides a detailed history of a 25-year-old male who was admitted with productive cough, hemoptysis, dyspnea on minimal exertion, fever, and chest pain. He had recurrent orchitis and epididymitis for 7 years, as well as oral and genital ulcers and severe headache. Clinical examination revealed decreased breath sounds at the right middle lung. Thoracic computed tomography angiography confirmed multiple pulmonary artery aneurysms bilaterally. The patient was diagnosed with Behçet's disease, and immunosuppression therapy was initiated. During follow-up, the patient did not report any complications. This case report underscores the significance for clinicians to consider Behçet's disease as a differential diagnosis in patients presenting with hemoptysis and a history of orchitis and epididymitis, given that Behçet's disease rarely causes pulmonary artery aneurysms.

Even though infected vasitis is rarely reported in the literature, there are other diagnoses that share the same clinical signs, including testicular torsion, epididymo-orchitis, epididymitis, trauma, and incarcerated hernia. A 27-year-old man was brought to the emergency department by his brother with right inguinal and testicular pain for one day. The history was not significant with fever, lower urinary tract symptoms, urethral discharge, change in bowel habits, previous history of inguinal swelling, or surgical intervention. On presentation, the patient was vitally stable, and right infra-inguinal and inguinal vas deferens were tender and swollen; however, both testes and epididymis were normal, and no urethral discharge. Vasitis, or inflammation of the vas deferens, is an uncommon illness that Chan PT and Schlegel classified as either asymptomatic vasitis nodosa or severely painful infectious vasitis. Acute infective vasitis is a really uncommon illness, with only a few occurrences documented in the literature. However, the retrograde transmission of urinary pathogens such as and is thought to cause acute vasitis. Because of its rarity and ambiguous imaging findings, diagnosing vasitis can be difficult. Epididymitis, orchitis, and testicular torsion can all be ruled out with ultrasound and duplex Doppler screening. Inguinal hernia is difficult to distinguish from vasitis with ultrasound; hence, CT and MRI are more commonly used to confirm the diagnosis. Since this is the first occurrence in our city that we are aware of, it was reported. A few cases from Saudi Arabia have also been documented, and by doing so, we may raise clinicians' awareness of this disease and ensure that they can treat patients without making an incorrect diagnosis.

STUDY QUESTION
Does the chemokine/chemokine receptor axis, involved in immune cell trafficking, contribute to the pathology of testicular inflammation and how does activin A modulate this network?
SUMMARY ANSWER
Testicular chemokines and their receptors (especially those essential for trafficking of monocytes) are elevated in orchitis, and activin A modulates the expression of the chemokine/chemokine receptor network to promote monocyte/macrophage and T cell infiltration into the testes, causing extensive tissue damage.
WHAT IS KNOWN ALREADY
The levels of CC motif chemokine receptor (CCR)2 and its ligand CC motif chemokine ligand (CCL)2 are increased in experimental autoimmune orchitis (EAO) compared with healthy testes, and mice deficient in CCR2 are protected from EAO-induced tissue damage. Activin A induces CCR2 expression in macrophages, promoting their migration. Moreover, there is a positive correlation between testicular activin A concentration and the severity of autoimmune orchitis. Inhibition of activin A activity by overexpression of follistatin (FST) reduces EAO-induced testicular damage.
STUDY DESIGN, SIZE, DURATION
EAO was induced in 10-12-week-old male C57BL/6J (wild-type; WT) and B6.129P2-Ccr2tm1Mae/tm1Mae (Ccr2-/-) mice (n = 6). Adjuvant (n = 6) and untreated (n = 6) age-matched control mice were also included. Testes were collected at 50 days after the first immunization with testicular homogenate in complete Freund's adjuvant. In another experimental setup, WT mice were injected with a non-replicative recombinant adeno-associated viral vector carrying a FST315-expressing gene cassette (rAAV-FST315; n = 7-9) or an empty control vector (n = 5) 30 days prior to EAO induction. Appropriate adjuvant (n = 4-5) and untreated (n = 4-6) controls were also examined. Furthermore, human testicular biopsies exhibiting focal leukocytic infiltration and impaired spermatogenesis (n = 17) were investigated. Biopsies showing intact spermatogenesis were included as controls (n = 9). Bone-marrow-derived macrophages (BMDMs) generated from WT mice were treated with activin A (50 ng/ml) for 6 days. Activin-A-treated or untreated BMDMs were then co-cultured with purified mouse splenic T cells for two days to assess chemokine and cytokine production.
PARTICIPANTS/MATERIALS, SETTING, METHODS
Quantitative real-time PCR (qRT-PCR) was used to analyze the expression of chemokines in total testicular RNA collected from mice. Immunofluorescence staining was used to detect activin A, F4/80, and CD3 expression in mouse testes. The expression of chemokine/chemokine-receptor-encoding genes was examined in human testicular biopsies by qRT-PCR. Correlations between chemokine expression levels and either the immune cell infiltration density or the mean spermatogenesis score were analyzed. Immunofluorescence staining was used to evaluate the expression of CD68 and CCR2 in human testicular biopsies. RNA isolated from murine BMDMs was used to characterize these cells in terms of their chemokine/chemokine receptor expression levels. Conditioned media from co-cultures of BMDMs and T cells were collected to determine chemokine levels and the production of pro-inflammatory cytokines tumor necrosis factor (TNF) and interferon (IFN)-γ by T cells.
MAIN RESULTS AND THE ROLE OF CHANCE
Induction of EAO in the testes of WT mice increased the expression of chemokine receptors such as Ccr1 (P < 0.001), Ccr2 (P < 0.0001), Ccr3 (P < 0.0001), Ccr5 (P < 0.0001), CXC motif chemokine receptor (Cxcr)3 (P < 0.01), and CX3C motif chemokine receptor (Cx3cr)1 (P < 0.001), as well as that of most of their ligands. Ccr2 deficiency reversed some of the changes associated with EAO by reducing the expression of Ccr1 (P < 0.0001), Ccr3 (P < 0.0001), Ccr5 (P < 0.01), Cxcr3 (P < 0.001), and Cx3cr1 (P < 0.0001). Importantly, the biopsies showing impaired spermatogenesis and concomitant focal leukocytic infiltration exhibited higher expression of CCL2 (P < 0.01), CCR1 (P < 0.05), CCR2 (P < 0.001), and CCR5 (P < 0.001) than control biopsies with no signs of inflammation and intact spermatogenesis. The gene expression of CCR2 and its ligand CCL2 correlated positively with the immune cell infiltration density (P < 0.05) and negatively with the mean spermatogenesis score (P < 0.001). Moreover, CD68+ macrophages expressing CCR2 were present in human testes with leukocytic infiltration with evidence of tubular damage. Treatment of BMDMs, as surrogates for testicular macrophages, with activin A increased their expression of Ccr1, Ccr2, and Ccr5 while reducing their expression of Ccl2, Ccl3, Ccl4, Ccl6, Ccl7 Ccl8, and Ccl12. These findings were validated in vivo, by showing that inhibiting activin A activity by overexpressing FST in EAO mice decreased the expression of Ccr2 (P < 0.05) and Ccr5 (P < 0.001) in the testes. Interestingly, co-culturing activin-A-treated BMDMs and T cells reduced the levels of CCL2 (P < 0.05), CCL3/4 (P < 0.01), and CCL12 (P < 0.05) in the medium and attenuated the production of TNF (P < 0.05) by T cells. The majority of cells secreting activin A in EAO testes were identified as macrophages.
LARGE SCALE DATA
N/A.
LIMITATIONS, REASONS FOR CAUTION
BMDMs were used as surrogates for testicular macrophages. Hence, results obtained from the in vitro experiments might not be fully representative of the situation in the testes in vivo. Moreover, since total RNA was extracted from the testicular tissue to examine chemokine expression, the contributions of individual cell types as producers of specific chemokines may have been overlooked.
WIDER IMPLICATIONS OF THE FINDINGS
Our data indicate that macrophages are implicated in the development and progression of testicular inflammation by expressing CCR2 and activin A, which ultimately remodel the chemokine/chemokine receptor network and recruit other immune cells to the site of inflammation. Consequently, inhibition of CCR2 or activin A could serve as a potential therapeutic strategy for reducing testicular inflammation.

Vasitis is inflammation of the vas deferens, which can be divided into acute inflammatory vasitis or chronic vasitis nodosa. Acute vasitis can present with inguinal pain, swelling, or a lump, which could mimic other common pathologies occurring at this site, particularly inguinal hernia. While ultrasound is effective in the diagnosis of epididymitis, orchitis, and hernia, this case illustrates the importance of cross-sectional imaging to establish the correct diagnosis of vasitis, to aid in the prevention of unnecessary surgical exploration and to expedite antibiotic treatment. Previous surgical intervention to the prostate is the leading risk factor for vasitis and should be taken into consideration when making a differential diagnosis and determining which image modality to use. Here, we present a case of vasitis in a 60-year-old male with previous Holmium laser enucleation of the prostate (HoLEP), with an initial diagnosis of inguinal hernia on ultrasound which was later diagnosed as acute vasitis on CT.

Review
Globally, ~8%-12% of couples confront infertility issues, male-related issues being accountable for 50%. This review focuses on the influence of gut microbiota and their metabolites on the male reproductive system from five perspectives: sperm quality, testicular structure, sex hormones, sexual behavior, and probiotic supplementation. To improve sperm quality, gut microbiota can secrete metabolites by themselves or regulate host metabolites. Endotoxemia is a key factor in testicular structure damage that causes orchitis and disrupts the blood-testis barrier (BTB). In addition, the gut microbiota can regulate sex hormone levels by participating in the synthesis of sex hormone-related enzymes directly and participating in the enterohepatic circulation of sex hormones, and affect the hypothalamic-pituitary-testis (HPT) axis. They can also activate areas of the brain that control sexual arousal and behavior through metabolites. Probiotic supplementation can improve male reproductive function. Therefore, the gut microbiota may affect male reproductive function and behavior; however, further research is needed to better understand the mechanisms underlying microbiota-mediated male infertility.

Xanthogranulomatous orchitis (XGO) is a benign non-inflammatory condition predominantly affecting the testicular tissue and characterized by the infiltration of lipid-laden macrophages leading to substantial tissue damage. We present the case of an 80-year-old gentleman with chronic pyocele and concurrent testicular atrophy secondary to XGO, a seldom-reported manifestation in the testicular milieu. The patient presented with a protracted history of left-sided scrotal swelling and underwent left orchidectomy subsequent to preoperative diagnosis via ultrasonography. Intraoperative exploration revealed the presence of purulent fluid, and histopathological analysis confirmed characteristic features of XGO, including seminiferous tubule destruction and infiltration of fibroconnective tissue by histiocytes and dilated blood vessels. Differential diagnosis with testicular neoplasms posed a challenge, accentuating the pivotal role of histopathological scrutiny in achieving precise diagnosis. Orchidectomy remains the cornerstone of treatment for XGO. This case underscores the imperative of considering XGO in the diagnostic spectrum of testicular masses and the indispensable role of histopathology in confirming the diagnosis and guiding optimal therapeutic interventions.

Testicular myeloid sarcoma (TMS) is a challenging pathology often posing diagnostic difficulties due to the poorly differentiated nature of tumor cells at the initial presentation. The delay in diagnosis significantly impacts patient life expectancy, emphasizing the need for prompt identification and treatment initiation. In certain cases, the presence of the Fms-like tyrosine kinase () mutation adds complexity to the disease, requiring tailored therapeutic approaches. In this report, we present a unique case of bilateral TMS with tyrosine kinase domain () mutation. The patient exhibited an aggressive clinical course, initially misdiagnosed with orchitis during the initial evaluation. Subsequent reevaluation of the testicular biopsy at a second center led to an accurate diagnosis, highlighting the importance of thorough examination in challenging cases. Given the emerging significance of mutations in myeloid sarcomas, comprehensive testing for all variants is crucial to determine the appropriate treatment modality. This case underscores the need for increased awareness among healthcare professionals regarding the diagnostic nuances and potential genetic variations associated with TMS. Furthermore, the inclusion of tyrosine kinase inhibitors, such as midostaurin or gilteritinib, especially in the presence of mutations, may significantly impact treatment outcomes. This report contributes to the growing body of literature on TMS and highlights the importance of considering mutations in the diagnostic and therapeutic decision-making process for improved patient care.

Infections and inflammatory reactions in the male genital tract are the leading causes of male infertility with a prevalence of 6%-10%, primarily affecting testicular and epididymal function and ultimately compromising sperm quality. However, most infertile patients with genital infection/inflammation are asymptomatic and easily overlooked. Traditional indicators, including white blood cells, elastase, and other components in semen, can reflect inflammation of the genital tract, but there is still a lack of a uniform standard method of detection. Therefore, it is necessary to explore reliable markers in semen that reflect the inflammatory status of the genital tract. Using the experimental autoimmune orchitis (EAO) model to simulate noninfectious chronic orchitis, we successfully collected ejaculated seminal fluid from EAO rats using optimized electrical stimulation devices. Proteomic analysis was performed using isobaric tags for relative and absolute quantification (iTRAQ). Compared to the control group, 55 upregulated and 105 downregulated proteins were identified in seminal plasma samples from the EAO group. In a preliminary screening, the inflammation-related protein S100A8/A9 was upregulated. We further verified that S100A8/A9 was increased in seminal plasma and highly expressed in testicular macrophages of the EAO model. In patients with oligoasthenospermia and genital tract infections, we also found that S100A8/A9 levels were remarkably increased in seminal plasma and testicular macrophages. S100A8/A9 in semen may be a potential biomarker for chronic genital inflammation. Our study provides a new potential biomarker for early diagnosis and further understanding of male infertility caused by genital inflammation.
