Varicocele, one of the main diseases affecting male reproductive health, relies heavily on angiographic diagnostic techniques for disease-related examination and assessment. Traditional varicocele angiography often employs a supine position to facilitate the relaxation of the groin area muscles, the insertion of the angiography catheter, and imaging. However, the supine position may cause blood reflux, thus underestimating the clinical incidence of varicocele, particularly resulting in missed diagnoses of right-sided or bilateral varicoceles.

Article Synopsis
  • * A study involving 96 patients who underwent microscopic subinguinal varicocelectomy (MSV) found significant increases in testicular arterial blood flow volume (TABFV) post-surgery, particularly for the left testis, which was more than double the preoperative level.
  • * Researchers developed a diagnostic model using preoperative TABFV and the presence of subclinical right-sided varicocele to predict semen improvement after MSV, achieving a strong performance with an area under the curve (AUC) of 0.824,

Background: Varicocoele is a correctable cause of male infertility. Although physical examination is still being used in diagnosis and grading, it gives conflicting results when compared to ultrasonography-based varicocoele grading.

Objectives: We aimed to develop a multi-class machine learning model for the grading of varicocoeles based on ultrasonographic measurements.

Retroperitoneal paragangliomas are tumors of neuroectodermal origin rarely appearing in the pediatric population. We report a case of a large paraganglioma infiltrating the right kidney and inferior vena cava in a 16-year-old boy who initially presented with a right-sided varicocele. Right retroperitoneal paraganglioma was embolized preoperatively, followed by total tumor excision, right nephrectomy, inferior vena cava resection, and reconstruction using a prosthetic vascular graft.

Unilateral right-sided varicocele is a rare and warning condition that should hint at a serious retroperitoneal disease such as renal cell neoplasm. Furthermore, its thrombosis is such an unusual entity that only a few cases have been described. We review the literature and report, to our knowledge, the second case of acute scrotal pain caused by unilateral right-sided varicocele thrombosis complicating an ipsilateral epididymo-orchitis, with no underlying coagulopathy or abdominal neoplasm, to illustrate the clinical, morphologic and therapeutic features of this entity.
