Can I take tiny infrequent doses of Ibuprofen

I am 70, in excellent health, and stage 3A kidney disease. I have been stable ever since I had a one time drop in function following high dose antibiotic treatment for a late diagnosed post knee surgery infection 3 years ago. My kidney doc left the practice and I cant see another one until March.
I had asked him if I could infrequently take just one dose of ibuprofen when I needed to. His answer was unclear (he was not a good communicator in general) but he was saying some infrequent small doses would be ok but no guarantees they wouldn’t lower the kidney performance. It was unclear exactly how much and how often. A doctor before him made a graph for me of where I am and how incredibly far away I am from dialysis. They always say the numbers are sort of estimates too?
Since then I have broken my back falling off my bike – all healed, but I have some now not bad hip pain from that – PT is helping but pain still builds if I have a busy day by the end of the day. I also have had my second gout attack and getting that in control. Hint – forget the nasty drugs and use lemon and cherry juices.
So for severe gout pain acetaminophen doesn’t help much and I would like to know if I can use ibuprofen – one dose only - if it happens. My wife and are hoping to ski – mostly X country – in Austria before my next meeting with a doctor and would like to know if I have this option. Or for a bad gout attack. It may hard to keep to my strict low uric acid diet while on vacation.
My eGFR is 42 and this is another question – my kidney tests don’t report uACR? Shouldn’t they? because I know that’s another key measure.
I think it would be safe to take one dose of ibuprofen if I continue my healthy habits and am not doing things – besides aging – that would hurt the kidneys.
Opinions? If you search this online the answer is always use acetaminophen and don’t take ibuprofen. Thanks
