Cryptorchidism (2/3) – Undescended Testicle: Symptoms and Diagnostic Work-Up
Signs and Symptoms of Cryptorchidism
- Missing testicle(s)
- incomplete descent or ectopic testicle(s)
- Hydrocele testis (open Proc. vaginalis)
- Inguinal hernia
Diagnostic Work-Up in Cryptorchidism
Palpation (search for a missing testis) should be done either in a relaxed supine position, while sitting (infants) or while standing (children). 80% of nondescended testes are palpable. For nonpalpable testes, 20% are missing, 30% are atrophic inguinal testes and 50% are abdominal testes.
Ultrasound is suitable for the location of the non-descended testes in the inguinal canal.
Laboratory tests are particularly indicated for bilateral nonpalpable testes.
An elevated FSH before puberty is a sign for bilateral missing testes.
HCG stimulation test:
An HCG stimulation test is indicated for bilateral nonpalpable testes: serum testosterone is measured before and 32 h after administration of 5000 IU HCG. An increase of testosterone proves the existence of dystopic testicle(s).
Inhibin is a testicular peptide hormone, which can predict testicular damage. Experimental examination.
When laparoscopy is able to identify testicular vessels and ductus deferens at the deep inguinal ring, an abdominal testis is not possible and inguinal exposure of the non-descended testis is done. If blind-ending testicular vessels are identified, the blind end is removed. If no testicular vessels are identified, the path of descent up to the lower pol of the kidney has to be searched.
