Thanks for the query to H.C.M. Forum.
Since there was blood in urine and your urologist
told that one ureter is small in size , so what this is a congenital deformity
and you were living very well before the episode of laryngitis
so need not to worry.
In such type of cases I usually prescribe Levomac + azithromycin
combination pack .
One dose at night time and this act as broad spectrum antibiotics and therapy .
This treatment ids just for 10 days , repeat after one month for another 10 days .
Plenty of fluid will help in this of cases.
Only one thing to remember that is serum creatinine
level , blood urea level.
These two parameters should be within limit and you will not feel any trouble for life long , I assure you ( about urinary system
The mass was of blood clot so biopsy proved it , need not to worry.
As far as concerned about bladder in mind , you are right ,but think as the ureter was since birth so why worry.
Still you feel any tension , consult a psychiatrist
and get his opinion.
