Hydrocele
What is a hydrocele
Excessive collection of serous fluid in tunica vaginalis
Why do hydrocele’s occur (2)
Problem w/ absorbing fl
Or too much fl = being produced
Congenital hydroceles
Assoc w/ hernia sac + patent processus vaginalis
Mx congenital hydroceles
Most spontaneously resolve <1y
Who gets 1’ hydroceles
Younger men
What is a 2’ hydrocele

What % of men have a varicoele
10%
PS varicoele
Pt complains of dragging sensation + ache
Bag of worms on palp
Varicoele + infertility
assoc w/ reduced spermatogenesis + subfertility
Which testicle > likely to have varicoele + why
L
Because L renal v drains at right angle vs R testicular vv which drains obliquely into IVC
Mx varicoele
