I'm not aware of any particularly popular ones. It's a rather niche concept, and not something that is commonly seen as a mainstream visual novel theme.
A 'gilrs desperate to pee visual novel' might be centered around the idea of female characters in a state of extreme need to pee. This could be used as a plot device to create tension, humor, or to explore aspects of human nature. For example, it could show how the characters react under this physical pressure, whether they try to find a solution discreetly or if they face embarassment. It might also look at how the other characters in the story respond to their situation, either with sympathy or perhaps with ridicule. The visual novel format would likely use images and text to tell this story in an engaging way.
