First of all , I would like to know the age of your husband and since how long he has been sufferring from this urinary problem.
I would also like to know more details about his urinary symptoms and would like to investigate him with USG of KUB with full bladder and post void residual urine.
Ideally, he needs to see a urologist
for proper examination, investigations and evaluation before any authentic advise can be given to him
If you wish you may bring him to the clinic for consultation and proper evaluation
