Hello and welcome to HCM.
As an
Urologist,i can understand your concern.
Let me state,that
appendectomy, isn't related to difficulty in urination.
Neither has it any role in ejaculation.
You should've stated his age and what medication he's on.
He'll need to see an Urologist. Tests needed,are urine and blood, routine with culture,
creatinine,RBS,PSA,and LFT. Then an
ultrasound scan-KUB is needed. Urologist will start antibiotic,if pain's due to infection.
If you've any doubt's,send it to me, as a direct question.
Dr.Matthew J. Mangat.
