Meta-Analysis Review
PURPOSE
The Testicular Workup for Ischemia and Suspected Torsion (TWIST) score is a 7-point tool to evaluate acute scrotal pain. Parameters include testicular swelling (2 points), hard testis (2), high-riding testis (1), absent cremasteric reflex (1) and nausea/vomiting (1). This review aimed to determine the diagnostic utility of TWIST and its role in risk stratification.
MATERIALS AND METHODS
A systematic review and meta-analysis of diagnostic test accuracy was conducted. Five risk stratification systems were explored, including the Barbosa (0-2, 3-4, 5-7) and Sheth (0, 1-5, 6-7) scoring systems, to obtain sensitivity, specificity and area under the receiver operating curve.
RESULTS
Thirteen studies were identified, 9 prospective studies proceeded to meta-analysis of diagnostic test accuracy and 5 pediatric studies (1,060 patients, 199 torsions) were included in the primary analysis. The most accurate risk stratification system was Barbosa (0-2, 3-4, 5-7), with an AUC of 0.924 (95% CI: 0.865, 0.956). Barbosa showed favorable sensitivity in low-risk patients (0.984), facilitating rule out of torsion, and favorable specificity (0.975) in high-risk patients, facilitating urgent surgical exploration. Sensitivity and specificity in intermediate-risk patients were 0.922 and 0.682, respectively, indicating a need for further workup with ultrasound. Using this stratification, 65.2% of patients were low-risk, 19.9% were intermediate-risk and 14.9% were high-risk. Per 100 presentations of acute scrotum, there was a missed torsion rate of 1.6/100, ultrasound rate of 19.9/100 and negative exploration rate of 2.5/100.
CONCLUSIONS
TWIST is an effective tool for suspected testicular torsion and is appropriate for widespread adoption. The Barbosa scoring system is reliable and reduces reliance on scrotal ultrasound.

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
INTRODUCTION
The bell-clapper deformity (BCD) predisposes to intravaginal torsion (IVT) and is classically bilateral. The precise pathological definition of what constitutes a BCD is not clear. The current study aims to clarify the specific anatomic details of this anomaly.
METHODS
A systematic review was performed utilizing the PRISMA principles. Studies are presented chronologically based on their level of evidence. They are further divided into study types: autopsy and operative studies of acute torsion, intermittent torsion and studies of the contralateral testis in vanishing testis.
RESULTS
The bell-clapper deformity is best defined by complete investment of the testis, epididymis and a length of the spermatic cord by the tunica vaginalis. Based on autopsy studies the rate of BCD in scrotal testis varied from 4.9% to 16%; with bilaterality in 66%-100%. In cases of acute IVT bilaterality was noted in 54%-100%. The most disparate results were in cases of testicular regression syndrome where contralateral BCD was noted in 0%-87% of cases.
CONCLUSION
We suggest future studies employ the strict anatomical definition above. As there is evidence of age-dependent investment of the testes, it will be important to develop age-standardized measurements of intravaginal length of spermatic cord. This critical morphometric measurement will allow a better understanding of the risk of IVT.

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.

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.

Andrology Jul 2021The 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. (Review)
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.

European Urology Focus Nov 2021Acute testicular torsion is a common urological emergency. Accepted practice is surgical exploration, detorsion, and orchidopexy for a salvageable testis. (Review)
Review
CONTEXT
Acute testicular torsion is a common urological emergency. Accepted practice is surgical exploration, detorsion, and orchidopexy for a salvageable testis.
OBJECTIVE
To critically evaluate the methods of orchidopexy and their outcomes with a view to determining the optimal surgical technique.
EVIDENCE ACQUISITION
This review protocol was published via PROSPERO [CRD42016043165] and conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA). EMBASE, MEDLINE, and CENTRAL databases were searched using the following terms: "orchidopexy", "fixation", "exploration", "torsion", "scrotum", and variants. Article screening was performed by two reviewers independently. The primary outcome was retorsion rate of the ipsilateral testis following orchidopexy. Secondary outcomes included testicular atrophy and fertility.
EVIDENCE SYNTHESIS
To our knowledge, this is the first systematic review on this topic. The search yielded 2257 abstracts. Five studies (n = 138 patients) were included. All five techniques differed in incision and/or type of suture and/or point(s) of fixation. Postoperative complications were reported in one study, and included scrotal abscess in 9.1% and stitch abscess in 4.5%. The contralateral testis was fixed in 57.6% of cases. Three studies reported follow-up duration (range 6-31 wk). No study reported any episodes of ipsilateral retorsion. In the studies reporting ipsilateral atrophy rate, this ranged from 9.1% to 47.5%. Fertility outcomes and patient-reported outcome measures were not reported in any studies.
CONCLUSIONS
There is limited evidence in favour of any one surgical technique for acute testicular torsion. During the consent process for scrotal exploration, uncertainties in long-term harms should be discussed. This review highlights the need for an interim consensus on surgical approach until robust studies examining the effects of an operative approach on clinical and fertility outcomes are available.
PATIENT SUMMARY
Twisting of blood supply to the testis, termed testicular torsion, is a urological emergency. Testicular torsion is treated using an operation to untwist the cord that contains the blood vessels. If the testis is still salvageable, surgery can be performed to prevent further torsion. The method that is used to prevent further torsion varies. We reviewed the literature to assess the outcomes of using various surgical techniques to fix the twisting of the testis. Our review shows that there is limited evidence in favour of any one technique.

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.

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.

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.
