Hello and welcome to HCM.
As an
Urologist,i can understand your concern.
I'm hopeful the scrotal
ultrasound scan, included a doppler scan.
Once that's done,a clear idea of the cause for the swelling of testis is known.
He should be using elevation of the
scrotum, at all times,to reduce swelling.
He should also use anti-inflammatory medicines, till the swelling reduces.
For difficulty in urination, he must have an urodynamic evaluation.
Personally, i don't see any reason for a neurology intervention.
If you want my expert opinion, send the report to me,as a direct question.
Dr.Matthew J. Mangat.
