Obstructive azoospermia (OA) is an important cause of male infertility, and epididymal OA (EOA) is a common disease. Microsurgical reconstruction is a common technique used in the treatment of EOA. In the present study, we analyzed the effectiveness of microsurgical vasoepididymostomy (MVE) at different levels and compared the differences among several MVE techniques.
A literature search was conducted in the PubMed, Web of Science, and Embase databases, according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The included studies were published in English until May 14, 2021. The R 4.1.2 software was utilized to evaluate the event rate, risk ratio (RR), and 95% confidence interval (CI).
A total of 51 studies involving 2853 patients with OA were included in our meta-analysis. The overall mean patency rate of patients who underwent MVE was 67.20% (95% [CI]:63.30%-71.10%), and the overall mean natural pregnancy rate of their partners was 40.05% (95% [CI]: 35.30%-45.60%). The pooled results showed that the patency rate of bilateral MVE was higher than that of unilateral MVE (RR = 1.42; 95% [CI]:1.25-1.61; p < 0.00). A comparison of the anastomotic site of MVE showed that the caudal/corpus area was favorable for the patency rate (RR = 1.17; 95% [CI]:1.04 - 1.32; p < 0.00). The caudal area was also advantageous for the patency rate (RR = 1.20; 95% CI:1.03 - 1.41; p < 0.04). Compared with typical MVE (65.20%, 95% [CI]:61.40%-69.10%), deferential vessel-sparing MVE with a higher overall mean patency rate (83.60%, 95% [CI]:75.40%-91.70%).
The meta-analyses indicated that MVE is a high- and cost-effective therapeutic method for patients with EOA, and deferential vessel-sparing MVE could be mainstream in the near future.

Live Broadcast of Surgical Procedures (LBSP) has gained popularity in conferences and educational meetings in the past few decades. This is due to rapid advancement in both Minimally Invasive Surgery (MIS) that enable transmission of the entire operative field and transmission ease and technology to help broadcast the operation to a live audience. The aim of this study was to update the evidence with specific emphasis on the patient safety issues related to LBSP in MIS.
A systematic review of the literature was performed using Medline, Embase and Pubmed using defined search terms related to LBSP in educational events across all surgical specialities, in accordance with the PRISMA guidelines. We also consolidated the prior guidelines and position statements on this topic. Outcomes included reports on the educational value of LBSP as well as patient safety outcomes and ethical issues that were captured by clinical outcomes.
A total 1230 abstracts were identified with 27 papers meeting the inclusion criteria (13 original articles and 14 position statements/guidelines). All studies highlighted the educational benefits of LBSP but without clear measure of these benefits. Clinical outcomes were not compromised in 9 studies but were inferior in the remaining 4, including lower completion rate of endoscopic surgery and higher rate of re-operation. Only nine studies complied with dedicated consent forms for LBSP with no consistent approach of reporting on maintaining patient confidentiality during LBSP. There was a lack of recommendation on standardised approach of reporting on LBSP including the outcomes across the 14 published guidelines and positions statements.
Live Broadcast of Surgical Procedures can be of educational value but patient safety may be compromised. A standardised framework of reporting on LBSP and its outcomes is required from an ethical and patient safety perspective.

Lumpy skin disease, sheeppox, and goatpox are notifiable diseases of cattle, sheep, and goats, respectively, caused by viruses of the Capripoxvirus genus. They are responsible for both direct and indirect financial losses. These losses arise through animal mortality, morbidity cost of vaccinations, and constraints to animals and animal products\' trade. Control and eradication of capripoxviruses depend on early detection of outbreaks, vector control, strict animal movement, and vaccination which remains the most effective means of control. To date, live attenuated vaccines are widely used; however, conferred protection remains controversial. Many vaccines have been associated with adverse reactions and incomplete protection in sheep, goats, and cattle. Many combination- and recombinant-based vaccines have also been developed. Here, we review capripoxvirus infections and the immunity conferred against capripoxviruses by their respective vaccines for each ruminant species. We also review their related cross protection to heterologous infections.

BACKGROUND: We report the case of a 43-year-old female patient with systemic lupus erythematosus, class III lupus nephritis, with predialysis creatinine levels around 350 μmol/L (3.95 mg/dL) after partial resection of the left kidney with histologically verified papillary carcinoma in 2010. Preoperative computed tomography of the abdomen revealed a small 8 mm tumor in the left upper kidney pole. The patient was indicated for simultaneous bilateral nephrectomy and orthotopic renal transplantation with the aim to minimize invasiveness of the procedure as well as for curable tumor removal.
METHODS: The procedure was performed under the full anesthesia trough upper middle laparotomy. As the first step, bilateral transperitoneal nephrectomy was performed. The live donor surgery started in a parallel theater to shorten the cold ischemic time of the graft. The renal graft had singe vessels and ureter; it was placed into the recipient\'s right orthotopic position. End-to-end anastomosis of the right renal vein and artery anastomosis were performed; ureter was anastomosed end-to-end using recipient\'s ureter.
RESULTS: The postoperative period was uneventful with repeatedly excellent ultrasonography check-up of the graft\'s perfusion. The patient was discharged after 13 days with a good renal function of the graft (urea: 15 mmol/L, creatinine 160 μmol/L [1.80 mg/dL]).
CONCLUSIONS: Orthotopic renal transplantation is a technically challenging but valid alternative for patients who are unsuitable candidates for heterotopic renal transplantation or in cases where there is a clear benefit of orthotopic renal transplantation.
