Gall Bladder Stone, Hernia and Hydrocyle

Good Evening Uncle. I am writing in reference to discuss the health issues of my father. He is 82  He has three issues Gall bladder stone( Size 12 mm) , Hernia in right abdomen and Hydrocele.        Though my father doesn't feel any pain as all  these things are not creating any problem yet. I have been to various doctors as they gave different opinion. Some suggest surgery as Gall Bladder stone should be on priority followed by Hernia and Hydrocele. Other suggest that he shouldn't undergo surgery as things are not creating trouble and he has age constraint as well so undergoing surgery might be risky. I have attached the UG report for your consideration. Please let me know your thoughts. Appreciate your efforts Raghav
