There are products, such as GoGirl.
GoGirl Female Urination Device
Ok, so what’s a GoGirl?
Simply put, GoGirl is the way to stand up to crowded, disgusting, distant or non-existent bathrooms. It’s a female urination device (sometimes called a FUD) that allows you to urinate while standing up. It’s neat. It’s discreet. It’s hygienic.
GoGirl is easy to use. Just lower your panties, and put GoGirl against your body, forming a seal. Aim and, well, pee. Pretty simple, huh?
GoGirl fits easily in your purse, pocket, or glove compartment. It’s a must for travel and sports. And it’s great for everyday––no more crouching over or trying to cover up an unsanitary public toilet.
While the concept may be new to you, European women have used female urination devices for years. GoGirl’s not the first device of its kind. But try it. And we think you’ll agree it’s easily the best.
Only GoGirl is made with flexible, medical grade silicone. Dispose of it after use. Or clean and reuse as you like. (Urine is sterile, but the product can come into contact with contaminates during use, so take precautions when cleaning.) Our patented splash guard eliminates messing and spilling. Once you practice a time or two, using a GoGirl is going to feel like second nature. You won’t be like a man. You’ll just pee like one.
Also, it is possible for women to urinate standing up, if you're willing to invest in a little potty self-training.

Fingers Method
1. Clean your hands.
2. Get into position.
* If you're urinating into a toilet, you can squat so that you hover over it, with your back facing the toilet. Your thighs should be as perpendicular to the floor as you can get them. If you can, hold onto something for balance. Your thighs might get a little sore when you first start doing this. If you're outside, you can lean against a tree, boulder, or whatever.
* If you're using a squat toilet, squat all the way down with your heels flat on the ground. If there are ridged foot rests, put your feet on those; otherwise, plant your feet on either side of the toilet.
* If you're using a urinal or just want to urinate standing up like guys do, spread your legs shoulder width apart and face your target. Bend your knees slightly, shift your pelvis forward, and lean back a little.
* Using this position, you shouldn't need to pull your pants down if you have a zipper or fly.3. Be ready with toilet paper or cloth in one hand in case the urine goes somewhere you don't want it to go.
4. Make a “V” with the first and second finger of your other hand and spread the inside of your labia minora, pulling upwards. You need to spread the inner labia so your urine will come forward in a stream and not run down your leg.[1] By adjusting how much you pull upwards, as well as the position of your hips, you can control where the stream goes (although it'll take a bit of practice).
5. Push your urine stream hard at the beginning and throughout to get a strong stream and not dribble.
6. When finishing up, stop suddenly to avoid dribbling. Make sure you're pushing hard up until that point.
Funnel Method
There are many products available so women can urinate in any position they want and control where the urine goes. Since each product is different, consult the instructions that came with it.
Tips
* Practice and practice! It is easiest when you are in the shower. Experiment with how far to separate your legs, how much to separate your labia and pull upwards, how much to bend your knees.
* Remember that while you may only be using a public toilet to urinate, other women may need to use it to defecate or sit for other reasons. So please be conscientious and lift the seat if at all possible. It's what would often be expected of a man who choses to urinate standing in a home bathroom, so please do other women the courtesy to lift the seat. This can be done using tissue to avoid direct contact of the seat with the skin.

Girls can pee standing up, and if they get good enough at the technique, they can pee through the fly of pants.
A girl can use her fingers, in an inverted "V", to spread her labia apart. This means both inner AND outer labia. Doing this clears the way for a solid pee stream to emerge, so that it doesn't run down the leg or spray everywhere. She often also needs to lift up on her "girl parts", to direct the stream forward instead of downward. Spreading the legs (to help "open things") and arching the body forward also aids in effective performance.
After she pees, she may need to stop rather abruptly in order not to dribble with the last bit of pee; such muscle control is aided through the performance of Kegel exercises. Alternatively, she may simply need to hold some toilet paper underneath to catch the dribble. But if the correct control is gained, she may be able to avoid wiping altogether, simply because there may be no mess or dribble involved.
It is recommended that this be practiced in the shower, where messes made during practice will not matter. While thus practicing, a girl can get used to exactly where to place her fingers and where exactly to pull to get the stream going correctly. I have read many stories of women practicing doing this until they got very good at it - so good that, with practice, they can go through the fly!
So as you can see, it is a myth that girls can't pee standing. Nor is there any reason to think it's "sick" or "perverse", as long as no sexual aspects are artificially read into it. Spreading the labia is no more "strange" than a boy holding his penis to aim when he pees; both are analogous to one another, as both allow proper aim in the different sexes.
I should mention in passing that IMO letting any girl know about this technique is doing her a service. I think every woman should know how to pee standing. For one thing, if they do it correctly, they will not have to remove much clothing if they need to pee in the wild or in a relatively non-private setting. They may also be able to get done quicker (if female urinals existed, a lot of problems involving enormous female restroom queues would be removed), and won't feel the need to either sit on or uncomfortably hover above filthy public toilet seats.
random thought after I finish my 2L water-cure-for-my-throat
I've been doing this for years. I was about 8 when I mastered the skill, and now im 15!
Agree with most of this except the female urinals at the end cutting down restroom lines - even if I could pee without removing any clothing I wouldn't want to do so in front of others (and my girlfriends say the same). So I think cubicles would still need to exist, but maybe smaller ones so more could be fitted in. This also leads to problems if u suddenly realize u want to do more than pee tho.
Yet they expect MEN to urinate in front of other men. Go figure.....
Yes, Justine, but men have 'built-in' Go-Girls and don't need to take any time preparing themselves for the spray. Agree with Sheree tho - I find a cubicle for a quick pee then more comes - a girlfriend says to me "use yr bum muscles to stop it" - but why? It'll need to come sooner or later anyway. I don't think we should be discriminated against just because we're made differently to men. We don't suggest THEY use anything other than razors on their facial hair!
