Surgical methods for varicocele remain controversial. This study intends to evaluate the efficacy and safety of different surgical approaches for treating varicocele through a network meta-analysis (NMA). PubMed, Embase, Cochrane, and Web of Science databases were thoroughly searched. In total, 13 randomized controlled trials (RCTs) and 24 cohort studies were included, covering 9 different surgical methods. Pairwise meta-analysis and NMA were performed by means of random-effects models, and interventions were ranked based on the surface under the cumulative ranking curve (SUCRA). According to the SUCRA, microsurgical subinguinal varicocelectomy (MSV; 91.6%), microsurgical retroperitoneal varicocelectomy (MRV; 78.2%), and microsurgical inguinal varicocelectomy (MIV; 76.7%) demonstrated the highest effectiveness in reducing postoperative recurrence rates. In this study, sclerotherapy embolization (SE; 87.2%), MSV (77.9%), and MIV (67.7%) showed the best results in lowering the risk of hydrocele occurrence. MIV (82.9%), MSV (75.9%), and coil embolization (CE; 58.7%) were notably effective in increasing sperm motility. Moreover, CE (76.7%), subinguinal approach varicocelectomy (SV; 69.2%), and SE (55.7%) were the most effective in increasing sperm count. SE (82.5%), transabdominal laparoscopic varicocelectomy (TLV; 76.5%), and MRV (52.7%) were superior in shortening the length of hospital stay. The incidence rates of adverse events for MRV (0), SE (3.3%), and MIV (4.1%) were notably low. Cluster analyses indicated that MSV was the most effective in the treatment of varicocele. Based on the existing evidence, MSV may represent the optimal choice for varicocele surgery. However, selecting clinical surgical strategies requires consideration of various factors, including patient needs, surgeon experience, and the learning curve.

The patient, a 20-day-old male, was admitted due to respiratory distress that had persisted for 20 days after birth. The main clinical manifestations included gradually worsening respiratory distress and edema. The patient received treatment including mechanical ventilation and diuretics. Echocardiography indicated cardiomegaly, pulmonary hypertension, and heart failure. A comprehensive systemic examination revealed a significant blowing vascular murmur upon auscultation over the anterior fontanelle and bilateral temporal regions. Further imaging studies including cranial magnetic resonance imaging, magnetic resonance angiography, and magnetic resonance venography showed marked dilation of the superior sagittal sinus, transverse sinus, and sigmoid sinus, leading to a definitive diagnosis of dural arteriovenous fistula. After a multidisciplinary consultation, the patient underwent cerebral angiography and partial embolization of the left parietal arteriovenous fistula. Postoperatively, the patient was treated with positive inotropes, diuretics, and fluid restriction. Ultimately, the patient was weaned off the ventilator and discharged in improved condition. This article reports a case of neonatal dural arteriovenous fistula presenting with respiratory distress and discusses the multidisciplinary approach to managing this condition, which aids in early disease recognition and guides clinical decision-making.

OBJECTIVE:
To investigate the effect of innovative perioperative pain management on prostate cancer patients with hematuria undergoing prostatic artery embolization (PAE).
METHODS:
A total of 60 patients undergoing PAE in the Interventional Therapy Department of General Hospital of Eastern Theater Command from May 2024 to January 2025 were selected by convenience sampling method and randomly divided into the intervention group and the control group, with 30 patients in each group. The control group received traditional pain management of nursing. An innovative perioperative pain management was performed in intervention group including preoperative "body-mind-pain" holistic assessment and preparation, intraoperative humanistic care and real-time support, postoperative multimodal analgesia and rehabilitation, dynamic monitoring and closed-loop feedback. The pain degree after 6 hours, 1 day, 3 days and 1 week of the operation, and the quality of life after 1 week of operation, as well as nursing satisfaction at discharge were compared between the two groups.
RESULTS:
The VAS scores of the intervention group were significantly lower than those of the control group after 6 hours, 1 day, 3 days and 1 week of operation (P<0.05). One week after the operation, the quality of life in the observation group was higher than that of the control group significantly (P<0.05). The nursing satisfaction of the observation group was significantly higher than that of the control group at discharge(P<0.05).
CONCLUSION
The application of innovative perioperative pain management can alleviate pain of patients with PAE, which improves the quality of life and nursing satisfaction of patients, and is conducive to the rehabilitation of patients.

5.Expert consensus on the bronchial artery embolization in the treatment of hemoptysis.
Chinese Journal of Internal Medicine 2025;64(3):191-199
Bronchial artery embolization (BAE) plays a crucial role in the treatment of hemoptysis, and its efficacy and safety have been proved. Although BAE is widely used in the treatment of hemoptysis, there is currently no standardized procedure for BAE, and there are significant differences between institutions and operators. To achieve standardization and normalization of the BAE in the treatment of hemoptysis, the Chinese College of Interventionalists (CCI) proposed this expert consensus, which is based on existing evidence and combined with clinical practice in China. This expert consensus is about patient selection, preoperative preparation, intraoperative procedures, postoperative management, efficacy evaluation and follow-up. After multiple rounds of discussion, this "expert consensus on the bronchial artery embolization in the treatment of hemoptysis" was proposed.

OBJECTIVE:
To assess the safety and efficacy of Neuroform Atlas stent used in treatment of unruptured wide-neck intracranial aneurysms.
METHODS:
Clinical data of 62 patients with unruptured wide-neck intracranial aneurysms undergoing Neuroform Atlas stent-assisted coiling from August 2020 to September 2021 were retrospectively analyzed. There were 64 aneurysms in those 62 patients. Among them, 25 aneurysms were located at the bifurcation of M1 segment on middle cerebral artery, 16 at the anterior communicating artery, 10 at the C7 segment of internal carotid artery, 5 at the C6 segment of internal carotid artery, 4 at the apex of basilar artery, 3 at the A3 segment of anterior cerebral artery, and 1 at the M2 segment of middle cerebral artery. All the patients underwent Neuroform Atlas stent-assisted coiling, including 49 patients with single stent assisted coiling and 15 patients with dual stents assisted coiling (14"Y"style and 1"X"style). After the procedure, the immediate DSA was performed to evaluate the status of aneurysm occlusion and the parent artery patency. The clinical follow-up was performed 3 months after the operation and evaluated based on the modified Rankin Scale(mRS).DSA image was reviewed at 6 months after operation and Raymond grading scale was used to assess the status of aneurysm occlusion and the parent artery patency.
RESULTS:
A total of 62 patients with 64 aneurysms were all achieved technical success(100%).The immediate post-procedural Raymond scale was assessed, including Raymond Ⅰ in 57 aneurysms(89.1%, 57/64), Raymond Ⅱ in 6 aneurysms(9.3%, 6/64) and Raymond Ⅲ in 1 aneurysm(1.6%, 1/64). The peri-procedural complications rate was 4.8%(3/62), 2 patients developed intraoperative thrombosis and 1 patient suffered from local subarachnoid hemorrhage. Among them, 55 patients obtained 3 months clinical follow-up after operation and all the patients had good outcomes (mRS≤2), 50 patients with 52 aneurysms were followed up with DSA 6 months after operation, including Raymond Ⅰ in 45 aneurysms(86.5%, 45/52), Raymond Ⅱ in 4 aneurysms(7.7%, 4/52) and Raymond Ⅲ in 3 aneurysms(5.8%, 3/52).
CONCLUSION
Neuroform Atlas stent for the treatment of unruptured wide-neck intracranial aneurysms has high safety and good efficacy, and has its advantages over other traditional stents.

9.Six novel minimally invasive therapies for benign prostatic hyperplasia.
Journal of Zhejiang University. Medical sciences 2023;52(2):162-168
Benign prostatic hyperplasia (BPH) is the most common cause of lower urinary tract symptoms in men. When drug treatment is ineffective or conventional surgery is not suitable, novel minimally invasive therapies can be considered. These include prostatic urethral lift, prostatic artery embolisation, water vapor thermal therapy, Aquablation-image guided robotic waterjet ablation, temporary implantable nitinol device and prostatic stents. These novel therapies can be performed in outpatient setting under local anesthesia, with shorter operative and recovery times, and better protection of ejaculatory function and erectile function. General conditions of the patient and advantages and disadvantages of the each of these therapies should be fully considered to make individualized plans.

Interventional embolization therapy is widely used for procedures such as targeted tumour therapy, anti-organ hyperactivity and haemostasis. During embolic agent injection, doctors need to work under X-ray irradiation environment. Moreover, embolic agent injection is largely dependent on doctors' experience and feelings, and over-injection of embolic agent can lead to reflux, causing ectopic embolism and serious complications. As an effective way to reduce radiation exposure and improve the success rate of interventional embolization therapy, embolic agent injection robot is highly anticipated, but how to decide the injection flow velocity of embolic agent is a problem that remains to be solved. On the basis of fluid dynamics simulation and experiment, we established an arterial pressure-injection flow velocity boundary curve model that can avoid reflux, which provides a design basis for the control of embolic agent injection system. An in vitro experimental platform for injection system was built and validation experiments were conducted. The results showed that the embolic agent injection flow speed curve designed under the guidance of the critical flow speed curve model of reflux could effectively avoid the embolic agent reflux and shorten the embolic agent injection time. Exceeding the flow speed limit of the model would lead to the risk of embolization of normal blood vessels. This paper confirms the validity of designing the embolic agent injection flow speed based on the critical flow speed curve model of reflux, which can achieve rapid injection of embolic agent while avoiding reflux, and provide a basis for the design of the embolic agent injection robot.
