The thing about all of this is-

There are some major differences when it comes to Bladder Evacuation with men and women. The major difference comes in the length of the urinary tract. A male's urinary tract is around 8 inches long, where as a female's urinary tract is around 3 or so inches long. The urine has far less distance to travel in a female case than a male.

There is also the fact that males require muscle movement and contraction to urinate. Female urination uses a great deal of gravity and the relaxation of muscles by contrast. This means, when the muscles relax after death, women are more likely to release the contents of their bladder than men are.

The type of death also plays a big part. Normal passing or dying typically doesn't bring out any type of evacuation. Violent deaths, like murders, accidents, the number is higher. However, it's the highest for both sexes in hanging. Females almost always lose bladder control during asphyxiation related deaths. Sometimes it happens just before the victim passes, or right after. But statistics have shown that it is extremely common in these types of deaths for females.

So, to answer your question, women are more likely to urinate after passing, but it mainly relies on the type of death.
