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.

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.

Meta-Analysis
INTRODUCTION
Challenges in identifying small testicular arteries and lack of microscopic experience have led to a rising trend in the use of laparoscopic technique for pediatric and adolescent varicocele. The controversy over artery ligation (AL) and artery preservation (AP) during laparoscopic varicocelectomy (LV) is still debatable. This study investigates the effectiveness of AL and AP during LV in pediatric and adolescent varicocele cases.
METHODS
The systematic searches based on PRISMA guideline were conducted in PubMed, Scopus, ScienceDirect, Web of Science and ProQuest databases with pre-defined keywords. Both quantitative and qualitative analyses were performed to assess catch-up growth, persistence, recurrence, hydrocele, operative time, post-operative testicular volume, and sperm analysis.
RESULTS
A total of 1512 patients from 9 eligible studies were included. There were no significant differences in catch up growth (OR 0.89; 95%CI 0.53, 1.51; p = 0.68) or hydrocele incidence (OR 0.59; 95%CI 0.28, 1.24; p = 0.16). The recurrence rate and persistence rate in AP group is significantly higher compared to AL group (OR 2.95; 95%CI 1.53, 5.68; p = 0.001 and OR 5.13; 95% CI 2.04, 12.88; p = 0.0005, respectively). The mean operative time during laparoscopic varicocelectomy is significantly longer when arteries are preserved as opposed to when they are ligated (OR 5.33; 95%CI 2.05, 8.60; p = 0.001). AL and AP both improved testicular volume and post-operative sperm analysis.
CONCLUSIONS
AL showed higher efficacy and comparable safety to AP. We recommend using AL with lymphatic sparing to minimize hydrocele complications.

Review
is a rare but serious condition characterized by twisting both testicles around their respective spermatic cords, leading to reduced blood flow and potential loss of the testicles. Treatment of this condition may involve surgical detorsion of the affected testicles and fixation to prevent recurrence and, in some cases, removal of severely damaged testicles. In April 2023, a systematic review of case reports was performed to examine the presentation, clinical features, diagnostic process, and management of bilateral testicular torsion. Our search encompassed the following databases: PubMed, ScienceDirect, and Google Scholar. Out of 340 studies, only eight cases met our criteria. However, this review discusses bilateral testicular torsion symptoms, investigation, and outcome.

Robot-assisted surgery is the gold standard of treatment in many fields of urology. In this systematic review, we aim to report its usage in andrology and to evaluate any advantages. A systematic search of the PubMed and Cochrane Library databases was conducted to identify articles referring to robotic-assisted microsurgery in andrology. The search strategy was in line with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and the Cochrane Handbook. The articles were then reviewed by two authors. A qualitative analysis of the articles that met the inclusion criteria was performed. Thirty-one articles that met the inclusion criteria were reviewed. The first results for robot-assisted vasovasostomy (RAVV) are encouraging as excellent patency rates, short operative times, and learning curves were achieved. Interestingly, patency rates were greater in some case series for RAVV than for microsurgical vasovasostomy, with a statistically significant difference. In addition, robot has been shown to be of great use in bypassing fibrotic changes in cases of iatrogenic vasal injuries, difficulties encountered with traditional microsurgery. In addition, the feasibility of robot-assisted microsurgery has been proven for varicocelectomy and microsurgical denervation of the spermatic cord, with acceptable improvement in sperm parameters and pain, respectively. The current evidence suggests that there are potential advantages of the use of robots in andrology. However, for robotic surgery to become incorporated into the daily use of the andrologists, large, multicenter randomized trials are needed. As robotics systems are becoming standard in urology practice, it is reasonable for one to believe that they will also find their place in andrology.

Review
BACKGROUND
Recurrent Testicular Torsion (RTT) is a rarely reported event after previous testicular torsion (TT) repair. Both conditions have similar signs and symptoms. Various techniques have been attempted to reduce the incidence of retorsion. This review assesses the presentation, diagnosis, risk factors, management and outcomes associated with RTT.
METHODS
After PROSPERO Registration (CRD42021258997), a systematic search of PubMed, Google Scholar, Embase, Scopus, Web of Science, Cochrane Database of Systematic Reviews, Global Index Medicus and Cumulative Index to Nursing and Allied Health Literature (CIANHL) was performed using specific search terms. Study metadata including patient demographics, orchidopexy techniques, RTT rates and RTT timing were extracted.
RESULTS
Twenty-six articles, comprising 12 case series and 14 case reports, with a total of 46 patients were included. Overall, the median (IQR) age of the pooled cohort was 18 (15-26) years, the median (IQR) time to presentation was 6 (3-36) hours from the onset of testicular pain. The most common presenting features were testicular pain (100%), testicular swelling (60.9%) and a high riding testicle (34.8%). The left testicle was most commonly affected (63.0%), RTT was on the ipsilateral side in relation to the primary episode of TT in 52.2% of cases, the median (IQR) interval between torsion and retorsion events was 4 (1.3-10.0) years, non-absorbable sutures were the most common suture material used during orchidopexy after RTT (88.9%).
CONCLUSION
RTT is a rare presentation to the Emergency Department. Even with a prior history of TT, RTT should be considered in patients presenting with classic symptoms.

Meta-Analysis Review
Comparison of the outcomes of testicular torsion among children presenting during the Coronavirus Disease 2019 (COVID-19) pandemic versus the pre-pandemic period: A systematic review and meta-analysis.
OBJECTIVE
To evaluate whether the Coronavirus Disease 2019 (COVID-19) pandemic resulted in a prolonged duration of symptoms, a delayed presentation to the medical facility, and consequently more orchiectomy procedures among children with testicular torsion compared to the pre-COVID-19 period.
METHODS
Systematic search of four scientific databases was performed. The search terms used were (coronavirus OR novel coronavirus OR SARS-CoV-2 OR COVID-19) AND (testicular torsion OR orchidectomy OR orchiectomy OR orchidopexy OR orchiopexy). The inclusion criteria were all boys presenting with testicular torsion during the COVID-19 and pre-COVID-19 periods. A comparison of the average duration of symptoms, the proportion of children with delayed presentation (>24 h), and the proportion of children requiring orchiectomy was made among the two groups. The Downs and Black scale was used for methodological quality assessment.
RESULTS
The present meta-analysis included six comparative studies (five retrospective studies). A total of 711 patients (473 during the COVID-19 period) were included. No significant differences in the average duration of symptoms (WMD: 2.6, 95% CI -6.78 to 11.99, P = 0.59), the proportion of children with delayed presentation (RR = 1.03, 95% CI 0.52-2.02, p = 0.94), and orchiectomy rate (RR = 1.23, 95% CI 0.82-1.84, p = 0.31) were observed among the two patient groups. All studies had a moderate risk of bias.
CONCLUSION
The duration of symptoms, the proportion of children with delayed presentation, and orchiectomy rate did not significantly differ among the children with testicular torsion presenting during the COVID-19 and pre-COVID-19 periods. However, due to the moderate risk of bias, the level of evidence of the available comparative studies is limited.

Review
BACKGROUND
Laparoscopic surgery is increasingly used to repair paediatric inguinal hernias and can be divided into intra- or extra-corporeal closing techniques. No statement regarding the superiority of one of the two techniques can be made. This study aims to provide evidence supporting the superiority of intra- or extra-corporeal suturing technique.
METHODS
A systematic literature search was conducted using PubMed, Embase, MEDLINE, and Cochrane Library databases. Randomised controlled trials and prospective studies comparing different laparoscopic techniques were eligible for inclusion. Data were pooled using a random-effects model, comparing single-port extra-peritoneal closure to intra-peritoneal purse string suture closing. Primary outcome was recurrence rate. Secondary outcomes were duration of surgery (min), peri‑ and post-operative complications (i.e. injury of spermatic vessels or spermatic cord, tuba lesions, bleeding and apnoea, haematoma/scrotal oedema, hydrocele, wound infection, iatrogenic ascent of the testis and testicular atrophy), contralateral patent processus vaginalis (CPPV) rate, post-operative pain, length of hospital stay and cosmetic appearance of the wound.
RESULTS
Fifteen studies (n = 3680 patients, age range 0.5-12 years, follow-up range 3-10 months) were included is this systematic review. Intra-corporeal hernia repair was performed in 738 children and extra-corporeal repair was performed in 2942 children. A pooled data analysis could only be performed for the single port extra-corporeal closing technique and the three port intra-corporeal closing technique. We found that recurrence rate was lower in the single-port extra-corporeal closing technique compared to the intra-corporeal purse suture closing technique (0.6% vs 5.5%, 95% CI 0.107 (0.024-0.477); p < 0.001). Operation time was shorter for extra-corporeal unilateral and bilateral inguinal hernia repair compared with intra-corporeal approach, but no pooled data analysis could be performed. Due to the presence of substantial heterogeneity, it was not possible to assess other outcome measures.
CONCLUSION
Single-port extra-corporeal closure seems to result in less recurrent hernias and a shorter operative time compared to intra-corporeal purse suture closing technique. No difference regarding peri‑ and post-operative complications could be found and no statements regarding the length of hospital admission, post-operative pain and cosmetics could be made due to substantial heterogeneity.

Review
BACKGROUND
The testes are suspected target organs of SARS-CoV-2. However, the results of studies on the effect of COVID-19 on male reproduction are controversial.
OBJECTIVE
To summarize current research on the effects of COVID-19 on male reproduction.
METHODS
A systematic review of English literature was performed using PubMed and Ovid Embase up to 18 August 2020. Research articles on the presence of SARS-CoV-2 in semen, the effects of the virus on semen parameters and any pathological changes in the testes were evaluated.
RESULTS
Fourteen studies were included in this review. Six of 176 survivors (3.4%) and 1 of 13 decedents (7.7%) in 2 of 12 studies were positive for viral RNA in semen and testicular tissue, respectively. After stratification of patient groups, we found that the virus was detected in the relatively early stage of infection, 6-16 days after disease onset, in semen from survivors. Two of 3 studies reported that some participants had substandard semen quality after COVID-19, and 1 study found that COVID-19 may impair semen quality in a severity-related manner. Pathological analyses showed that injuries to the seminiferous tubule occurred in all decedents (N = 11). Another study found that orchitic and testis fibrin microthrombi occurred in patients with fatal disease (100%, N = 2). Scrotal discomfort of orchiepididymitis or spermatic cord inflammation has also been reported in COVID-19 patients.
CONCLUSION
Current studies suggest that semen is rarely considered a carrier of SARS-CoV-2 genetic material during the infection period but not in the semen of recovered patients. Fatal COVID-19 may cause testicular structure damage without the presence of virus.

A spermatic cord lipoma is found in 20-70% of all inguinal hernia repairs. The clinical picture of an inguinal hernia with bulging and pain but without an actual indirect hernia sac may become manifest in up to 8% of these cases. Missed spermatic cord lipoma can result in recurrence or pseudo-recurrence. This review presents the relevant literature on this topic. A systematic search of the available literature was performed in February 2020 using Medline, PubMed, Google Scholar, Scopus, Embase, Springer Link, and the Cochrane Library, as well as a search of relevant journals and reference lists. Forty-two publications were identified as relevant for this topic. Spermatic cord lipoma seems to originate from preperitoneal fatty tissue within the internal spermatic fascia in topographical proximity to the arteries, veins, lymphatics, nerves, and deferent duct within the spermatic cord. Reliable diagnosis cannot be made clinically, but rather with ultrasound, CT, or MRI. In the absence of a real hernia sac, a spermatic cord lipoma is classified as a lateral inguinal hernia with a defect size <1.5 cm according to the European Hernia Society (EHS LI). Missed or inadequately treated spermatic cord lipoma results in recurrence or pseudo-recurrence. Since spermatic cord lipoma obtains its vascular supply from the preperitoneal space, it can be reduced or resected. Spermatic cord lipoma is a common finding in inguinal hernia repairs and must be properly diagnosed and treated with care respecting the anatomy of the spermatic cord.
