Varicocele embolization with sclerosing agents leads to lower radiation exposure and procedural costs than coils: Data from a real-life before and after study

Current drawbacks and future perspectives in the diagnosis and treatment of male factor infertility, with a focus on FSH treatment: an expert opinion

PURPOSE

Infertility is defined as the inability to conceive after 1 year of unprotected intercourse, affecting approximately 15-20% of couples in Western countries. It is a shared problem within the couple; when the main issue lies with one of the partners, it is preferable to refer to "male factor" or "female factor" infertility rather than simply male or female infertility. Despite male factor infertility accounting for half of all couple infertility cases, the clinical approach to the male partner is not uniformly standardized across international guidelines.

METHODS

To provide an expert overview, we have comprehensively reviewed and critically analyzed the most up-to-date literature on this sensitive topic, leading to the development of a proposal for tailored assessment of the diagnostic-therapeutic pathway and preventive strategies. The diagnostic approach also considers that infertile men are objectively less healthy than their fertile counterparts of the same age and ethnicity.

RESULTS

This article discusses the diagnostic flow, the classification of male factor infertility, the definition of idiopathic infertility, the involvement of general health, and treatment recommendations, emphasizing follicle-stimulating hormone treatment in selected groups of patients.

CONCLUSION

We provide expert opinion on current drawbacks and future perspectives in this field, with practical advice for the clinical practice of general practitioners and expert in reproductive medicine.

Comparing the efficacy of different embolisation materials in improving pain and fertility outcomes in patients with varicoceles: A systematic review

Radiological embolisation has emerged as a safe and effective alternative to surgery for varicocele treatment. While systematic reviews have compared embolisation to surgery, attempts to compare different embolisation materials have been limited. The objective was to conduct a systematic review assessing the potential benefits of combining coils with sclerosants for varicocele embolisation on fertility, pain, recurrence and complication rates in male patients, as compared to using coils alone. The search was conducted through MEDLINE, Embase and CENTRAL databases from inception to May 2023. Comparative studies that reported male varicocele patients treated with embolisation using either coils or coils with sclerosants were included, with primary outcomes of either fertility, pain or recurrence. Pearling of reference lists was also performed to identify additional articles. Risk of bias for each study was assessed using the Downs and Black Checklist. Overall, 21 studies (2236 patients) were included. Patients were treated with coils in 14 studies, and nine studies used coils with sclerosants. An improvement in sperm concentration and motility was identified post-embolisation in most studies that reported these outcomes. Pregnancy and recurrence rates were comparable between the two materials. All four studies that reported pain outcomes following embolisation noted improvement in pain scores. Only one comparative study was included, for recurrence. This review has identified improvements in pain and fertility following varicocele embolisation. However, it could not be determined which material was superior due to the lack of high-quality comparative studies in the literature.

[Varicocele and male infertility]

BACKGROUND

Varicocele is the most common correctable cause of male infertility. It was the subject of recent Association française d'urologie (AFU) Comité d'andrologie et de médecine sexuelle (CAMS) recommendations. Since then, the literature has provided additional information. This review will comprehensively reassess current indications for the treatment of varicocele, and revisit contemporary issues in the light of current advances.

METHODS

Update of the literature search carried out as part of the CAMS recommendations for the period between 2020 and 2023.

RESULTS

Microsurgical sub-inguinal varicocelectomy remains the surgical treatment of choice for infertile men with clinical varicocele and abnormal sperm parameters. It offers recurrence rates of less than 4%. It significantly improves both natural and in vitro fertilization live birth and pregnancy rates, as well as sperm count, total and progressive motility, morphology and DNA fragmentation rates. All in all, it modifies the MPA strategy in around one in two cases. Varicocele grade and bilaterality are predictive of improved sperm parameters and pregnancy rate. Treatment of subclinical varicocele is not recommended. Complications are rare, notably hydroceles (0.5%), unilateral testicular atrophy due to arterial damage (1/1000), hematomas, delayed healing and postoperative pain. Retrograde embolization is an alternative to surgery.

CONCLUSION

Whenever possible, the urologist should present and discuss treatment options for varicocele with the MPA team and the patient, taking a personalized approach.

Radiation Exposure and Surgical Outcomes after Antegrade Sclerotherapy for the Treatment of Varicocele in the Paediatric Population: A Single Centre Experience

INTRODUCTION

Antegrade sclerotherapy (Tauber) effectively treats varicocele. However, fluoroscopy exposes young males to ionizing radiation. We aimed to evaluate radiation exposure and surgical outcomes after the Tauber procedure.

MATERIALS AND METHODS

We retrospectively analysed data from 251 patients. Dose area product (DAP) and fluoroscopy time were recorded. The effective dose was calculated with the PCXMC software. Descriptive statistics and linear regression tested the association between clinical predictors and radiation exposure.

RESULTS

Median (IQR) age and body mass index (BMI) were 14 (13-16) years and 20.1 (17.9-21.6) kg/m². Five (2.1%) patients developed clinical recurrence and two (0.81%) developed complications. Median fluoroscopy time and DAP were 38.5 (27.7-54.0) s and 89.6 (62.5-143.9) cGy*cm². The effective dose was 0.19 (0.14-0.31) mSv. Fluoroscopy time was higher in patients with collateral veins (41 (26-49) s vs. 36 (31-61) s, p = 0.02). The median amount of sclerosing agent (SA) used was 3 (3-4) ml. DAP was higher when SA > 3 mL was used (101.4 (65-183) cGy*cm² vs. 80.5 (59-119) cGy*cm²; p < 0.01). At univariable linear regression, age, BMI, operative time and SA > 3 mL were associated with higher DAP (all p < 0.01). At multivariable linear regression, only BMI (beta 12.9, p < 0.001) and operative time (beta 1.9, p < 0.01) emerged as predictors of higher DAP, after accounting for age and SA > 3 mL.

CONCLUSIONS

The Tauber procedure is safe and associated with low effective doses. Operative time and the patient's BMI independently predict a higher radiation dose.

CIRSE Standards of Practice on Varicocele Embolisation

BACKGROUND

Percutaneous embolisation is an effective, minimally invasive means of treating a variety of benign and malignant lesions and has been successfully used to treat varicoceles since the late 1970s, with refined and expanded techniques and tools currently offering excellent outcomes for varicocele embolisation.

PURPOSE

This document will presume that the indication for treatment is clear and approved by the multidisciplinary team (MDT) and will define the standards required for the performance of each modality, as well as their advantages and limitations. CIRSE Standards of Practice documents are not intended to impose a standard of clinical patient care, but recommend a reasonable approach to, and best practices for, the performance of percutaneous varicocele embolisation.

METHODS

The writing group was established by the CIRSE Standards of Practice Committee and consisted of five clinicians with internationally recognised expertise in embolisation of male varicoceles. The writing group reviewed the existing literature on varicocele embolisation, performing a pragmatic evidence search using PubMed to search for publications in English and relating to human subjects published from 2006 to 2021. The final recommendations were formulated through consensus.

CONCLUSION

Embolisation has an established role in the successful management of male varicoceles. This Standards of Practice document provides up-to-date recommendations for the safe performance of varicocele embolisation.
