Undescended testes

Undescended testes

A normally descended testis reaches the scrotal floor with a good cord length above it and remains there. Testicular descent is usually complete by the 30th week of gestation. At birth, 4% of full-term and 30% of premature boys have an undescended testis (UDT). Boys should be examined at birth and at 6 weeks; if a UDT is found, they should be seen at 3 months since a testis is unlikely to descend after this time. An orchidopexy is then scheduled for between 6 and 12 months. Occasionally a palpable UDT undergoes torsion and presents as a painful lump in the groin with an empty hemi-scrotum. Clinical examination distinguishes a normal testis from a palpable or an impalpable UDT . A testis cannot be palpated in the canal; it can only be felt when delivered to the super ficial pouch, which is also called Denis Br owne’s pouch (a pocket between Scarpa’s fascia and the external oblique fascia Anton Nuck , 1650–1692, Dutch anatomist and surgeon who described the peritoneal outpocketing neighbouring the round ligament of the uterus as it extends to the labia majora.

Ectopic testes are found beneath the skin of the medial thigh or lower abdomen; they have a long cord, facilitating easy scrotal placement at operation.
