BACKGROUND
Testicular cancer is the most common solid tumor affecting men aged 20-39 years old. About 95% of all testicular tumor is testicular germ cell tumor. Bilateral testicular tumor is a rare incident and has similar histopathology only in less than 5% of all testicular cancer patients. Besides oncological issues, bilateral testicular tumors could lead to further consequences, such as psychosocial and hormonal issues. This article shows a case of different histopathology in the metachronous bilateral testicular tumors.
CASE PRESENTATION
A 34-years-old male came with right radical orchiectomy due to testicular pure seminoma pT1N0M0S0 three and half years ago. He underwent bleomycin, etoposide phosphate (BEP) chemotherapy for progressive multiple lymphadenopathies in paracaval and interaortacaval region from positron emission tomography (PET)/computerized tomography (CT) scan a year later. Sperm banking was done before initiated chemotherapy. High metabolic activity was detected in contralateral testis from follow up PET-scan. Left testicle enlargement with hard consistency was found on physical examination and there is an elevation of alpha-feto protein (AFP) and β-hCG. Intraoperatively, the frozen section identified a malignant tumor and the patient was decided to undergo radical left orchiectomy. Postoperative pathological results showed a mixed germ cell tumor of 3.5 × 2.5 × 2 cm consisting of immature teratoma, yolk sac tumor and embryonic carcinoma without lympho-vascular invasion and involvement of the spermatic cord. Post-operative imaging and testicular tumor marker did not identify any metastases. BEP chemotherapy, testosterone replacement therapy was planned for further management in this patient with complete blood count, prostate serum antigen (PSA) and digital rectal examination should be measured three to six weeks after initiation.
CONCLUSION
Metachronous bilateral TGCT with different histopathology is a rare disease. The treatment depends on histology of second tumor and its stage. TRT is mandatory for patient undergoing bilateral orchidectomy to address lack if testosterone.

Review
Oxidative stress refers to a condition where there is an imbalance between the production of reactive oxygen species and their removal by antioxidants. While the function of reactive oxygen species as specific second messengers under physiological conditions is necessary, their overproduction can lead to numerous instances of cell and tissue damage. Nuclear factor erythroid 2-related factor 2 (Nrf2) is a master regulator of many cytoprotective genes that respond to redox stresses. Nrf2 is regularly degraded by kelch-like ECH-associated protein 1 through the ubiquitin-proteasome pathway. The kelch-like ECH-associated protein 1 and Nrf2 complex have attracted attention in both basic and clinical infertility research fields. Oxidative stress is implicated in the pathogenesis of female infertility, including primary ovarian insufficiency, polycystic ovarian syndrome, and endometriosis, as well as male infertility, namely varicocele, cryptorchidism, spermatic cord torsion, and orchitis. Most scientists believe that Nrf2 is a potential therapeutic method in female and male infertility disorders due to its antioxidant effect. Here, the potential roles of oxidative stress and Nrf2 in female and male infertility disorders are reviewed. Moreover, the key role of Nrf2 in the inhibition or induction of these diseases is discussed.

Review
INTRODUCTION
it is estimated that approximately 20 million people undergo inguinal hernia surgery annually in the world, with the Lichtenstein technique being the most performed surgical procedure. The objective of this study is to analyze the knowledge of the technical principles used in the Lichtenstein technique.
METHOD
Survey-type intersectional study approved by the research ethics committee of São Camilo University Center (CAAE: 70036523.1.0000.0062). During the research period, 11,622 e-mails were sent to members of the main national surgical societies with research on the technical principles of Lichtenstein surgery. The survey was carried out using an electronic form with 10 multiple-choice questions. The form was answered anonymously on the SurveyMonkey and Google Forms platforms.
RESULT
744 responses were received to the electronic form. Based on this number of respondents, our survey has a confidence level of 95% with a margin of error of 3.5%. It was observed that there is no standardization of the technique among the majority of responders (53.4%). Many surgeons still perform digital dissection of the spermatic cord (47%). A small number of interviewees (15.2%) performed sutures with absorbable thread in the region of the internal oblique aponeurosis, while more than half (55.2%) continued to perform sutures with non-absorbable thread. Most surgeons use a small overlap or fix the mesh juxtaposed to the pubic symphysis (51%).
CONCLUSION
Our research identified that a small percentage of respondents adequately know the technical principles of Lichtenstein surgery. The result brings us new insights into the need to review Lichtenstein technique.

Testicular torsion is a urological emergency. However, surgical detorsion of the torsed spermatic cord can cause testicular reperfusion injury. Although remote ischemic preconditioning (RIPC) has been convincingly shown to protect organs against ischemia/reperfusion (I/R) injury, little is known regarding the effect of RIPC on testicular torsion/detorsion-induced reperfusion injury. Therefore, we aimed to evaluate the effect of RIPC on testes after testicular I/R injury in a rat model in vivo. Male Sprague-Dawley rats were randomly classified into 4 groups: sham-operated (sham), testicular I/R (TI/R), or remote liver (RIPC liver) and limb (RIPC limb) ischemic preconditioning groups. Testis I/R was induced by 3 h of right spermatic cord torsion (720° clockwise), and reperfusion was allowed for 3 hours. In the RIPC group, four cycles of 5 min of ischemia and 5 min of reperfusion were completed 30 min prior to testicular torsion. The ERK1/2 inhibitor U0126 was administered intravenously at the beginning of reperfusion (1 mg/kg). The testes were taken for the oxidative stress evaluations, histology, apoptosis, immunohistochemical and western blotting analysis. Remote liver and limb ischemic preconditioning attenuated ipsilateral and contralateral testicular damage after testicular I/R injury. For example. RIPC reduced testicular swelling and oxidative stress, lessened structural damage, and inhibited the testicular inflammatory response and apoptosis. Furthermore, RIPC treatment enhanced testicular ERK1/2 phosphorylation postI/R. Inhibition of ERK1/2 activity using U0126 eliminated the protection offered by RIPC. Our data demonstrate for the first time that RIPC protects testes against testicular I/R injury via activation of the ERK1/2 signaling pathway.

BACKGROUND
Orchialgia is not an uncommon complaint among men with varicocele, but postvaricocele embolization-related testicular pain has not been widely investigated. This study evaluates the phenomenon of postvaricocele embolization pain (PVEP) syndrome and examines the current strategies to treat this unusual complication.
METHODS AND MATERIALS
A prospectively collected database of patients with PVEP who presented to a tertiary center was analyzed between January 2011 and January 2020 following internal ethics approval. Patient demographics, including other complications related to embolization, analgesic requirements, and pain scores (on a 10-point visual analog score), treatment strategies, Patient Global Impression of Improvement (PGI-I) score and overall satisfaction score (on a 5-point scale), were reviewed. All patients were reviewed for a minimum of 12 months.
RESULTS
A total of 20 men with a mean age of 33.8 (18-45) years old, presented with PVEP over 10 years. Most men received embolization on an average of 26.6 (18-48) months. The reasons for varicocele embolization include either isolated or combined orchialgia (15 men), subfertility (5 men), and cosmesis (6 men). Eighteen (90%) men underwent microscopic spermatic cord denervation (MSCD) and 2 patients elected for conservative measures. The average pain scores pre-MSCD and post-MSCD were 6.9 (4-9) and 1.4 (0-4) (p<0.001) with a significant reduction in analgesia requirements. Immediate improvement in pain score was reported in all the patients and this persisted at the 12 months review. Most men reported a high satisfaction score (of 4/5) and only one patient reported no change in symptoms after MSCD.
CONCLUSION
PVEP is a unique complication and patients should be counseled on the potential risk of persistent orchialgia following embolization for varicocele. The MSCD appears to be an effective treatment option with high success and satisfaction rates.

OBJECTIVE
Factors associated with testicular torsion (TT) and consequent orchiectomy in patients presenting to pediatric emergency departments (PEDs) with scrotal pain (SP) are not well described. We report the factors predicting TT and consequent orchiectomy in children with SP.
METHODS
The data on patients (aged ≤18 years) who presented with SP to PEDs at 4 branches of the Chang Gung Hospital through 10 years were analyzed.
RESULTS
In all, 256 pediatric patients presented with SP. Their mean age was 11.60 ± 4.61 years and 72.7% (n = 186) were aged 10 to 18 years. The pain was left-sided in 54.7% (n = 140) and the interval between SP onset and PED arrival was 22.45 ± 31.27 hours. Overall, 84 (32.8%) patients needed surgery and 72 (28.1%) had TT. Of the patients with TT, 28 (38.9%) patients needed an orchiectomy. After analysis, TT and consequent orchiectomy were associated with a longer interval between SP onset and PED arrival, absent of testicular ultrasonic blood flow, interval between SP onset and surgery of more than 24 hours, and a high degree of TT. None of them experienced recurrent SP symptoms or TT again.
CONCLUSIONS
The rate of TT in patients presenting to PEDs with an SP was 28.1%, and 38.9% of the patients with TT needed an orchiectomy. Early diagnosis and intervention helped to prevent subsequent orchiectomy in pediatric patients with TT.

INTRODUCTION
Acute scrotum is a common presentation in the pediatric population and can indicate serious conditions such as testicular torsion, in which quick diagnosis and treatment is crucial for increasing the chances of a favorable outcome. During the COVID-19 pandemic, even patients with serious conditions, had delayed presentations and in-hospital management, resulting in worse outcomes.
OBJECTIVE
The aim of the study was to evaluate the safety of ultrasound in diagnosing pediatric acute scrotum and to identify delays from onset of symptoms until surgical exploration. Additionally, we wanted to gauge the impact of COVID-19 pandemic on delay and outcome.
METHODS
Medical records of patients aged 1-16 years seen with acute scrotum at the authors' University Hospital from 2017 to 2020 were reviewed, and 438 patients in 467 individual visits were included. Information on demographics, symptoms, ultrasound results, outcome, and time courses were retrieved and analyzed with regards to outcome and the presence COVID-19.
RESULTS
We did not find the use of ultrasound to increase the risk of orchiectomy (OR 2.259 (0.387-13.195)), however patients undergoing ultrasound had a significantly longer pre-hospital ischemia time, and therefore an increased orchiectomy rate. Delay between referral and presentation was the greatest predictor of orchiectomy in testicular torsion (OR 1.031 (1.003-1.060)), while in-hospital delay did not increase the risk of orchiectomy (OR 0.998 (0.992-1.004)). Time courses and outcome did not significantly differ before- and during the COVID-19 pandemic.
DISCUSSION
The primary contributor to ischemic time in testicular torsion was pre-hospital delay, and neither in-hospital delay nor the delay incurred by use of ultrasound affected the outcome. This might be explained by timely in-hospital management and ultrasound only being used selectively in patients with a lower clinical suspicion of testicular torsion and in those with prolonged symptom duration. During the COVID-19 pandemic, pre- and in-hospital delay as well as outcome did not differ significantly from pre-pandemic measures, which indicates that parents felt safe approaching the healthcare system, and resources were sufficient to handle this patient group in spite of an ongoing pandemic. The current study is limited by its retrospective design, and relatively small group of testicular torsion patients.
CONCLUSION
We found ultrasound to be safe in diagnosing pediatric acute scrotum. Furthermore, it can be inferred that measures aimed at reducing pre-hospital delay could potentially increase the salvage rate in testicular torsion. We did not find COVID-19 to affect either outcome or time to treatment in testicular torsion.

AIMS
The aim of this study was to investigate the potential antioxidant, anti-inflammatory, and sperm function-preserving properties of sodium acetate (ACE), a histone deacetylase (HDAC) inhibitor, in a rat model of testicular torsion/detorsion (T/D).
MAIN METHODS
Littermate Wistar rats of identical weight were subjected to sham surgery or testicular T/D by rotating the left testis at 720° around its axis along the spermatic cord clockwise and fixing it in this position for two and a half hours. 1 h before detorsion, T/D + ACE-treated rats were treated with ACE (200 mg/kg/day, per os) while T/D rats were vehicle-treated by administering 0.5 mL of distilled water. After 72 h, animals were euthanized, and the left testes were harvested for bio-molecular and histological analysis.
KEY FINDINGS
Acetate administration attenuated T/D-induced rises in serum and testicular HDAC and testicular xanthine oxidase, uric acid, MDA, GSSG, MPO, TNF-α, IL-1β, IL-6, NFkB, HIF-1α, and VCAM-1. In addition, acetate treatment alleviated T/D-induced decline in sperm quality (count, motility, viability, and normal morphology) and testicular 3β-HSD, 17β-HSD, testosterone, GSH, GSH/GSSG, SOD, catalase, GPx, GST, Nrf2, and HO-1. Furthermore, acetate prevented T/D-distorted testicular histoarchitecture and spermatogenic germ cell loss.
SIGNIFICANCE
Sodium acetate during the post-ischaemic phase of testicular T/D may be beneficial in preventing I/R injury and maintaining fertility.

Review
BACKGROUND
The effect of pediatric inguinal hernia repair (IHR) on testicular vascularization remains unclear. Manipulating the spermatic cord during surgery may reduce blood flow due to edema and vasoconstriction. This can lead to testicular atrophy. The study aims to review current knowledge of testicular vascular impairment following IHR in children.
METHODS
A systematic literature search was conducted in PubMed/Medline, Embase, Cochrane Library, and Web of Science. Methodological quality was assessed using validated tools. Data were extracted, and a pooled data analysis was performed.
RESULTS
Ten studies were included in the systematic review. Six of these studies were eligible for meta-analysis. This revealed a significant decrease in testicular vascularization during the short-term follow-up (1 day-1 week) after IHR using the open surgical approach. This decrease was not present after laparoscopic intervention. There was no more increased resistance in the vessels at long-term follow-up (1 month-6 months), suggesting that the impaired vascularity is only temporary.
CONCLUSIONS
There seems to be a short-term transient vascular impairment of the testis after open IHR in children. This might be of clinical relevance to prefer the laparoscopic approach for IHR in children, even though the open approach is the gold standard, in contrast to adult IHR. The impact on testicular function and sperm quality later in life remains unclear. Comparative studies of both techniques are needed to determine if there is a significant difference in testicular vascularity. Long-term studies are necessary to assess the impact of transiently reduced vascularity on sperm quality and fertility later in life.

Para testicular or intra-scrotal Rhabdomyosarcomas (RMS) are rare. The spindle cell variant of rhabdomyosarcoma is the least common variant among embryonal subtypes. They are mostly seen in childhood but rarely reported in adults. We present a case of a 56-year-old man who presented with a three-year history of painless left inguinoscrotal swelling, which he initially ignored and misinterpreted as an Inguinal hernia but later sought medical help upon a progressive increase in the size of the swelling. Clinically and radiologically, there was sparing of the left testis and spermatic cord with normal testicular tumor markers and no evidence of lymphadenopathy or metastasis. Surgical exploration was performed with complete excision of the mass, followed by histopathology and immunocytochemistry, confirming the diagnosis of spindle cell rhabdomyosarcoma. Prompt recognition, early diagnosis, and appropriate surgical treatment are the hallmarks of management. Regular and strict follow-up is needed due to the rarity of diagnosis.
