Review
PURPOSE
Contrast-enhanced ultrasound (CEUS) has been increasingly used for the diagnostic identification of neoplasms due to its ability to visualize the microvascularization of lesions. In the study of testicular abnormalities, the appropriate use of CEUS can improve the diagnostic accuracy of conventional gray-scale ultrasound and color Doppler ultrasound (CDUS). The purpose of this study is to comprehensively evaluate the diagnostic performance of CEUS in testicular space-occupying lesions.
METHODS
A comprehensive search of PubMed, Embase, Cochrane Library, and Web of Science databases was conducted from the inception of each database to November 16, 2022 for relevant studies. The required data were extracted, and the methodological quality of the studies was assessed using the QUADAS-2 tool. The diagnostic value of CEUS was assessed by calculating the combined sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, and diagnostic odds ratio, and a summary receiver operating characteristic (SROC) curve was used to conduct this meta-analysis.
RESULTS
A total of six studies with 354 testicular space-occupying lesions were included in the analysis. The results showed that CEUS could provide additional useful information for the diagnosis of testicular space-occupying lesions, with a sensitivity of 0.92 (95% CI:0.82, 0.97), specificity of 0.91 (95% CI:0.80, 0.96), diagnostic odds ratio of 114 (95% CI:25, 528), respectively, and an overall diagnostic accuracy expressed as area under the SROC curve (AUC) of 0.97 (95% CI:0.95-0.98). Significant heterogeneity was seen in the sensitivity with I = 82.53% (95% CI:69.44-95.61). Subgroup analysis revealed that the proportion of infertile patients selected may be the source of heterogeneity.
CONCLUSION
CEUS can be used to diagnose testicular space-occupying lesions more accurately and improve diagnostic accuracy when the conventional US cannot accurately differentiate the type of lesion. In particular, CEUS should be recommended for the identification of microscopic lesions so that physicians can provide patients with more appropriate interventions to avoid unnecessary orchiectomy.

AIM
Liposarcoma of the spermatic cord (LSC) is a tumour often mistaken for common inguinal swelling as hernia and the aim of this work is to present our case with a review of the Literature to define the management of this rare condition.
MATERIAL OF STUDY
A systematic review has been realised, considering English language articles published on Pubmed, between 1956 and 2022, using as key words "Liposarcoma of the spermatic cord".
RESULTS
160 studies described 420 cases of LSC and in 40 cases the patient had undergone surgery with an initial diagnosis of inguinal hernia.
DISCUSSION
LSC is a very rare entity of genitourinary malignancies, occurring more often in the spermatic cord and diagnosis can be difficult. Our case and Literature data confirm the role of imaging in not conventional inguinal swelling, to avoid diagnostic mistakes and to define preoperatively the correct surgical management.
CONCLUSIONS
Imaging is mandatory in case of diagnostic doubt. The recommended treatment is a radical high orchiectomy with clear margins. A long follow-up period is necessary to detect a local recurrence which may occur even several years after the primary therapy.

Scrotal tumors of nerve origin are extremely rare and occur mostly in the extratesticular tissues of scrotum, such as the spermatic cord and epididymis. A systematic search of the literature in PubMed, Medline, and Google Scholar databases concerning intrascrotal nerve tumors was performed by 2 independent investigators. The systematic search retrieved 45 male adults, with a mean age of included patients at 43.9 ± 18.8 years. The majority of nerve tumors were extra-testicular (86.7%), and only 13.3% originated from the testis. Out of that, 51.1% of neoplasms were histologically proved as schwannomas, 44.4% as neurofibromatosis, and 4.4% as malignant peripheral nerve sheath tumors. The majority of patients presented with atypical symptoms such as scrotal swelling (51.1%), while only 4.4% of patients were asymptomatic. Ultrasonography is the diagnostic modality of choice (97.2%) for the detection of primary lesion, while magnetic resonance imaging and computed tomography comprise supplementary diagnostic tools. Surgical excision of the mass was the preferred type of surgery performed (75.6%), whereas orchiectomy was performed only in 22.2% of patients. Intrascrotal tumors of nerve origin are extremely rare neoplasms that present mainly in middle-aged males. Increased clinical suspicion is required for accurate diagnosis of this rare entity.

Review
Most genitourinary tract cancers have a negative impact on male fertility. Although testicular cancers have the worst impact, other tumors such as prostate, bladder, and penis are diagnosed early and treated in relatively younger patients in which couple fertility can be an important concern. The purpose of this review is to highlight both the pathogenetic mechanisms of damage to male fertility in the context of the main urological cancers and the methods of preserving male fertility in an oncological setting, in light of the most recent scientific evidence. A systematic review of available literature was carried out on the main scientific search engines, such as PubMed, Clinicaltrials.Gov, and Google scholar. Three hundred twenty-five relevant articles on this subject were identified, 98 of which were selected being the most relevant to the purpose of this review. There is a strong evidence in literature that all of the genitourinary oncological therapies have a deep negative impact on male fertility: orchiectomy, partial orchiectomy, retroperitoneal lymphadenectomy (RPLND), radical cystectomy, prostatectomy, penectomy, as well as radiotherapy, chemotherapy, and hormonal androgen suppression. Preservation of fertility is possible and includes cryopreservation, hormonal manipulation with GnRH analogs before chemotherapy, androgen replacement. Germ cell auto transplantation is an intriguing strategy with future perspectives. Careful evaluation of male fertility must be a key point before treating genitourinary tumors, taking into account patients' age and couples' perspectives. Informed consent should provide adequate information to the patient about the current state of his fertility and about the balance between risks and benefits in oncological terms. Standard approaches to genitourinary tumors should include a multidisciplinary team with urologists, oncologists, radiotherapists, psycho-sexologists, andrologists, gynecologists, and reproductive endocrinologists.

Review
Standard care for stage I testicular germ cell cancers (seminomatous-STC or non-seminomatous-NSTC) is orchiectomy followed by active surveillance, 1 or 2 cycles of adjuvant chemotherapy, surgery or radiotherapy. The decision on the adjuvant therapeutic approach is guided by the associated risk factors of the patient and the potential related toxicity of the treatment. Currently, there is no consensus regarding the optimal number of adjuvant chemotherapy cycles. Although in terms of overall survival, there is no proven inconsistency regarding the number of cycles of adjuvant chemotherapy, and the rate of relapse may vary.

BACKGROUND
Orchiectomy has been replaced by medication represented by luteinizing hormone-releasing hormone (LHRH) agonist as the first-line therapy for androgen deprivation therapy (ADT). After the wide application of LHRH agonist, the side-effects of long-term ADT were noticed. It is time to reconsider the role of medication and surgeries in the treatment of prostate cancer.
METHODS
Embase, Pubmed, Web of science and Cochrane library were searched for relevant trials. Quality of the studies and risk of bias were assessed by using the Newcastle-Ottawa Scale (NOS). Therapeutic and adverse effects, as well as long-term metabolic adverse effects were extracted from the selected studies. The data synthesized in meta-analyses were performed with R software (4.2.1). Risk ratio (RR) with its 95% confidence interval (CI) was calculated by combining outcome data including complete and partial response rate, progression rate, death rate and adverse effects such as hot flash and increase in pain. Descriptive analysis was performed among the prostate specific antigen (PSA), testosterone and metabolic adverse effects due to a lack of homogeneity of frailty measures.
RESULTS
1,711 participants from 11 studies were included in our systematic review. 1,258 patients from six studies were included in the meta-analysis. Based on the meta-analysis, the therapeutic and adverse outcomes included overall response rate, complete response rate, partial response rate, stable rate, progression rate, death rate and hot flashes. No statistical significance was observed between LHRH agonists and orchiectomy. Compared with surgery, LHRH agonist elevated the risk of the increase in pain. In descriptive analysis, it was shown that the therapeutic effects between PSA and testosterone also showed no significant difference. Both groups had lipid and glucose metabolic disorders, and a few studies reported worse lipid metabolic performance in orchiectomy group and worse insulin resistance in LHRH agonist group.
CONCLUSION
We found that the therapeutic outcomes were similar between the two options. The results of lipid and glucose metabolic abnormality were controversial in existing studies. The direct comparison studies on metabolic adverse effects should be performed in the future. The therapeutic, metabolic, psychological and economical effects should be considered before applying ADT methods.

INTRODUCTION
To consolidate reported information on presentation, diagnosis, and treatment modalities in testicular schistosomiasis (TS) to provide a reference tool for this rare disease.
MATERIALS AND METHODS
A comprehensive PubMed search was performed using PRISMA guidelines, which yielded 21 articles detailing 22 cases of TS.
RESULTS
Testicular schistosomiasis remains a rare disease, presenting at a variety of ages (median age 27). All reports of this condition are associated with exposure to an endemic area. The most common presenting symptoms include nonspecific testicular swelling (54.5%) followed by a testicular mass/nodule (18.4%). Diagnosis relies upon clinical suspicion due to low specificity on laboratory and imaging evaluation, with only 18% of urine evaluations positive for parasitic infection. Final diagnosis was made on biopsy (38.1%), radical orchiectomy (47.6%) or frozen section during partial orchiectomy (14.3%). Treatment included anthelmintic mediation (37%), radical/partial orchiectomy (31%), or some combination of the above.
CONCLUSIONS
This systematic review of individual patient data reveals that while urine tests and imaging may aid in diagnosis, all patients require definitive histologic diagnosis. It is important to obtain a thorough history to elucidate exposure to endemic areas and inform whether biopsy, and subsequent testicular preservation, may be appropriate.

Meta-Analysis
INTRODUCTION
Since the onset of coronavirus disease 2019 (COVID-19), stay-at-home orders and fear caused by the pandemic have had a significant effect on the timing and outcomes of testicular torsion. However, the evidence was limited since the study results were inconsistent. This study aims to examine the hospitalization rates, timing, and outcomes of testicular torsion in children before and during the pandemic.
MATERIALS AND METHODS
Using PubMed, Embase, and Google Scholar databases, we conducted a systematic search and meta-analysis of studies reporting the timing and outcomes of children admitted with testicular torsion before and during the COVID-19 pandemic. Subgroup analyses were conducted to explore possible sources of heterogeneity.
RESULT
The outcomes of 899 testicular torsion patients from eight studies were evaluated. Our study found an increased hospitalization rate for patients with testicular torsion (incidence rate ratio = 1.60, 95% confidence interval [CI]: 1.27-2.03; = 0.001). Despite a significant increase in the duration of symptoms during the COVID-19 pandemic (weighted mean difference = 11.04, 95% CI: 2.75-19.33; = 0.009), orchiectomy rates did not increase (odds ratio = 1.33, 95% CI: 0.85-2.10; = 0.147).
CONCLUSION
During the COVID-19 pandemic, hospitalization rates for testicular torsion and the duration of symptoms among children increased significantly. Moreover, the rate of orchiectomy did not increase during the pandemic, indicating that pediatric emergency services have remained efficient and have prevented an increase in the number of orchiectomies performed despite pandemic-related closures and delays in transporting patients to medical care.

Review
CONTEXT
Unlike palpable lumps, a large number of nonpalpable testicular lesions found incidentally at ultrasound in asymptomatic postpuberal males are either benign tumours or non-neoplastic lesions. The prevalence of malignancy, however, is appraised based on small case series. Dedicated studies report a large number of patients, and systematic review articles are lacking.
OBJECTIVE
This systematic review is aimed to assess, from the analysis of the pooled data of the available literature, the incidence of benign tumours, malignant tumours, and non-neoplastic lesions, and to identify predictive characteristics for malignancy.
EVIDENCE ACQUISITION
A systematic review of PubMed, Scopus, Google Scholar, Turning Research Into Practice (TRIP) database, and the Cochrane Library was conducted on January 6, 2022, according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement. Studies were retrieved reporting on adult asymptomatic men, with single, incidentally identified small testicular lesions, either fertile or infertile, with negative tumour markers and without specific risk factors for malignancy. Lesions ≤20 mm were considered small. Seventy-four studies were selected for inclusion in this analysis. Twenty-six additional publications have been retrieved by the bibliography quoted in the selected articles.
EVIDENCE SYNTHESIS
Pooled data of 1348 lesions in 1348 patients were collected. Of these lesions, 408 could be retrieved individually, 44.6% were benign, 27.2% were malignant, and 20.8% were non-neoplastic. Virtually all lesions <3 mm and 86.6% of lesions <5 mm were benign. Lesions >10 mm have a 38.14% probability of being benign. Hyperechoic lesions are likely benign. Fertility status does not affect the risk of malignancy.
CONCLUSIONS
Very small (<3 mm) and small (<5 mm) incidentally detected testicular lesions in asymptomatic postpuberal men with normal tumour markers could be frequently benign. More prospective studies are needed to better support this finding. Management strategies should be developed for these patients to reduce overtreatment.
PATIENT SUMMARY
Small testicular lesions are incidentally founded at ultrasound. It is not easy to distinguish a benign lesion from a malignant one. Results of this study are reporting a higher incidence of benign lesions with a diameter of <5 mm. More studies are needed to better understand the biology and the management strategy for small testicular lesions.

Review
Management of incidentally diagnosed small testicular masses (STM) is controversial. Although there is the risk of malignancy, it might be realistic to safely seek preservation of testicles bearing benign masses. This study aims to systematically evaluate the evidence regarding prevalence of STMs, their benign or malignant histology and their management. We conducted a systematic literature search for studies reporting small or incidental testicular masses and their management by radical orchiectomy, testis sparing surgery (TSS) or ultrasound (US) surveillance. We initially screened 2126 abstracts and from these, 57 studies met the inclusion criteria. Testicular masses were detected in 1.74% of patients undergoing US examination. Regarding STMs removed by surgery, 41.12% were benign. Intraoperative frozen section examination (FSE) is a reliable tool to discriminate between benign and malignant testicular masses (average 93.05% accuracy), supporting TSS. Benign lesions were associated with smaller diameter (<1 cm 68.78% benign), were often hypoechoic and exhibited regular margins on US. Conclusions: Small testicular masses are often benign. Clinical and US patterns are not accurate enough for including patients in surveillance protocols and TSS paired with FSE is pivotal for precluding the removal of testicles bearing benign lesions. Future research might unveil new imaging tools or biomarkers to support clinical management.
