Dear anavette (love your screen photo!): The period question is the easiest place to start. As you likely know, any of the endometrial ablation (EA) techniques try to destroy all of the uterine lining tissue. Yet it can be difficult to reach up into the high corners of the uterus (around where the Fallopian tubes enter into the uterine cavity. Over time any minute amounts of lining tissue, stimulated by your natural estrogen levels, will attempt to regrow and repopulate the inside of the uterus. This can manifest as very scant spotting.
There are MANY studies which have compared at least two of these methods to see if one method is superior, or works better with a certain type of patient. For example 126 women were randomly assigned to NovaSure or ThermaChoice procedures.
Five years after procedure, no further menstruation ("amenorrhea") was reported by 48% in the Nova Suret group and 32% in the balloon group. Unfortunately, most of the comparison studies have had small numbers of women.
So if type of EA procedure seems to be generally equal, can we identify specific women who might not have as good an outcome based upon her medical history or personal anatomy? You may have read that large fibroids sticking out into the uterine cavity can impede the correct placement of NovaSure, or that a very large uterine cavity (e.g., greater than 5 inches) can be harder to treat.
Physicians from the Mayo Clinic reviewed the outcomes of 816 women who had an EA. Factors which seemed to predict successful stopping of all bleeding ("amenorrhea") included: age 45 or older (menopause would be kicking in within 5 years or so), a thin uterine lining of less than 4 mm, normal size of uterine cavity (less than 9 cm), and use of NovaSure type rather than heated balloon. Patient characteristics linked to treatment failure were: age younger than 45 years, five or more pregnancies (leads to larger uterine size), prior tubal ligation, and history of bad menstrual cramps.
So what about the sudden urine incontinence? A lit search at the National Library of Medicine site found only one citation linking increased urine leaking with a tubal ligation---but it was a 1983 study using outdated surgical methods to do the tubal. Thus it seems less likely that this was caused by something your GYN did.
I would urge you to either return to the original GYN, or get a second opinion, about the type and possible causes of the current urinary incontinence. While the spotting is probably within the range of normal after an EA, urinary issues are not and need to be evaluated. Here is a link to more information about the types and causes of incontinence:
