I know that odor, my parents house wreak of it because they didn't throw out into the trash bin their Depends quick enough, plus there were accidents where they didn't get to the bathroom on time. Mom tried to clean the carpeting, but at 97 it was hard for her to do. And they become nose blind to the smell. There wasn't anything I could do as it was their house, they refused caregivers and cleaning crews, and proudly said "we can manage".
Since you have control of your house, you can wash Mom's clothes using 20-Mule Team Borax, that helped when I needed to wash my Mom's clothing when she was in long-term-care. Try Lysol spray around the house or any other type of spray that doesn't just mask the smell [that is if no one is allergic to that smell and you have no pets as pets are super sensitive to those sprays].
If MIL soils the furniture, buy "blue sheets" to put down on the sofa or upholstered chairs. Those blue sheet you can toss out when soiled. You can try buying them at the pet store, puppy aisle, to try them out. Then go on-line where you can purchase a large carton full.
If MIL's depend type garment isn't working, try different brands and styles until there is one that works the best. MIL can also use Poise type pads in her Depends and those pads can be tossed out.
Does she wear a diaper? Does she shower regularly? How dark is the urine? I would add more water and cranberry juice to her diet (as long as she doesn't have CHF and has to limit liquid). It will make her pee more but the pee will be more diluted. I would also get the perineal spray on cleanser to make sure that she's getting clean between voids. Also, it's important to make sure she's totally dry including the area where the legs meet the private parts and if she's heavy, under the stomach. It's been a hot summer and the moisture can make a ton of smelly bacteria. You said that she doesn't have a UTI, could she have a yeast infection? If not, try the options above. She should optimally be drinking her weight in ounces during the summer, at least that's what the nutritionist told me to do with my patient.
Desenex anti-fungal (foot) powder in the diaper when it is put on. Also use the powder in skin folds, like under the breast and tummy fold. If her kidneys are failing, the urine smell is actually on her skin, so make sure she has a good soap or body wash. Get her a bath aide weekly if you can, they do a really good scrubbing.
When washing her clothes and bedding use baking soda in the wash or white vinegar. ( DO NOT use both items at same time. ) 100% polyester is an odor absorbent magnet. Very difficult to remove odors from 100% poloyester. Use air freshner that actually states "Odor Neutralizer/Neutralizing" on can. Have her drink more water...it may help dilute her urine making it less concentrated & strong smelling. If liquid intake is restricted try Vitamin C tablets or capsules. Ask her PCP prior to giving her the vitamin C .
