You don't need to answer a bunch of silly and pointless questions about your husbandry. I'm sure it's probably just fine. If the vet couldn't tell you what was likely causing this then it's not very likely that someone can give you a viable or accurate diagnosis over the internet based on a typed account of the frequency of the liquid urine or the completeness of a shed.
I seriously doubt if it has anything to do with the humidity as I have seen this condition before developing in well hydrated reptiles kept in extremely high humidity. It could just be the anatomy of that particular snake and perhaps a flaw in her waste anatomy. Perhaps this flaw causes her to form overly large solid urates that cause blockage. Or perhaps she has a much smaller cloaca than a normal burmese. In any case just do what you need to do to remedy this. But try switching her to small rabbits )1-2 lbs) and see if this ailment doesn't go away. Give her a tub large enough to soak in. She probably won't use it much, but at least it will be there if she should want to soak. I personally think that she will likely outgrow whatever is causing this.
>>I've had this snake since receiving it from Bob Clark from a newborn. She eats 1 large (rodentpro) rat every 7 days. Living in Syracuse NY where the winters are harsh to say the least my house heat is going constantly so the humidity isn't the greatest 45-50% even though I mist and what not. Temps are 85-90 on warm side and around 78-80 om the cool. She has a UTH which is on all the time and a overhead heat lamp on a timer. Currently in a glass cage with screen top, the top is 70% covered with a wet towel. A new cage will be coming soon. Her water bowl is cleaned and refilled at least every 3 days, but not big enough to soak in. She shows no signs of dehydration.
