Hydrocele: Pathogenesis and Clinical Findings

Non-communicating:

 - Localized infection or trauma

 - Previous varicocelectomy or inguinal surgery

 - Testicular or scrotal malignancy

-> Impaired fluid drainage

-> Imbalance between secretion and absorption of fluid in tunica vaginalis

Communicating:

 - Congenital patent processus vaginalis

 - Communication between peritoneal cavity and the scrotum

 - Free flow of peritoneal fluid into tunica vaginalis

-> Accumulation of fluid within tunica vaginalis

-> Hydrocele

Notes:

• Hydroceles are typically asymptomatic.

• Communicating hydroceles may produce a cough impulse or decrease in size after laying down.
