Male GU

Question 1

Epididymo-orchitises

Answer 1

Epidemiology:
Kids: congenital GU abnormality → gram neg rods (e coli)
Sexually active young men: gonorrhoea and C trachomatis
Older than 35: pseudomonas

Gonorrhoea: suppurative if severe → abscesses

Mumps: systemic infection, if in school aged kids tend to not have testicular involvement, however if post pubertal, orchitis occurs in 20-30%
Orchitis typically develops 1 week after onset of swelling of parotid glands

TB: always begins in epididymis, may spread to testis. Caseating granulomatous inflammation

Syphillis: may be affected in congenital and acquired syphilis
testis is always involved first, and often epididymis is spared all together (although may be involved)
