I am not an expert with the female urination anatomy, but I do know that both males & females have internal & external urinary sphincters (the anatomy differences are more complicated than this simple statement, but hear me out). The internal sphincter is under INVOLUNTARY control (like your heart muscle) and is supposed to automatically stay shut until your bladder sends a message to your brain that it's "time to go". Your external sphincter is under VOLUNTARY control and makes sure you don't go until you are sitting on the toilet. Once you're ready, your brain tells your internal sphincter to release, and you voluntary release your external sphincter...and you go!
If you are unconsciously having small leaks my guess is that your internal sphincter is not closing completely. This could be due to many factors. I had a surgical procedure to remove calcium stones from my prostate & bladder neck (which blends into the internal sphincter), and my urologist permanently damaged my internal sphincter. It's like having a bad washer on an old faucet. No matter what you do, the doggone thing is going to drip!! My diagnosis was intrinsic sphincter deficiency (ISD). Some of the medications you mentioned are helping me, but not like you might think. My new urologist (I fired the one that did my surgery) has me taking these meds to reduce spasms that are putting extra pressure on my sphincter, literally forcing urine out of me. As long as I keep the spasms to a minimum, my drip....drip....dripping is less.
I hope this helps. Good luck!
