What does an Orchidometer measure?

What does an Orchidometer measure?
An orchidometer is a medical instrument that can be used to accurately measure volume and determine the size of the testicle.
What is LSVC?
Persistent left superior vena cava (LSVC) is the commonest congenital anomaly of the thoracic venous system. It is within the group of anomalous systemic venous return (ASVR) and the group is subdivided in cephalic, involving the superior vena cava (SVC) and caudal, involving the inferior vena cava (IVC) types.
What causes Plsvc?
The presence of the left anterior cardinal vein and obliteration of the left common cardinal vein leads to the formation of the left superior vena cava, which drains into the right atrium through the coronary sinus. The presence of a PLSVC has a significant influence on the anatomy of the heart and venous system.
How do you use an orchidometer?
To use an orchidometer, doctors gently pull the testicle to the bottom of a boy’s scrotum and use touch and sight to find the bead that matches it in volume.
What is the normal position of testis?
Normal scrotal position: When in normal position, the testes are positioned at or below the midpoint of the scrotum without palpable tension on the spermatic cord.
What is double SVC?
Double SVC is a rare anatomical variant that results from a persistent left superior vena cava, which is due to the embryological failure of regression of the anterior cardinal vein.
What is left sided SVC?
A left-sided SVC forms when the left anterior cardinal vein is not obliterated during normal fetal development. The persistent left-sided SVC passes anterior to the left hilum and lateral to the aortic arch before rejoining the circulatory system.
How is superior vena cava syndrome diagnosed?
A plain chest x-ray may show abnormal enlargement of the mediastinum or may reveal a tumor in the lung. Ultrasound may be used to look for blood clots in the arm leading into the chest. Computerized tomography (CT) scanning of the chest is most often used to diagnose superior vena cava syndrome.
