It can sometimes take 10 or 20 or 25 flushes, before gallbladder is strong enough to push the stones out. But, over 90% of people will achieve it within 8 flushes.
The stones you got in the first 3 flushes were most likely from inside your liver bile ducts.
If stones are significantly larger then cystic duct (gallbladder throat), then they will never be able to exit gallbladder, unless you dissolve them. Radish juice is suppose to be able to dissolve some kind of gallstones.
I say some kind, because Gallstones
may be comosed of different % percentage of cholesterol, protein, calcium, pigment, ... and no 2 stones in the world are equal, and no 2 stones in the world would respond same to dissolving attempt.
Radish juice (fresh), apple juice (fresh), castor oil packs, coffee enema, Fish Oil, Flax oil, Silver Shark Oil, "lecithin" (around 2400 to 4800 mg of lecithin a day), one or more 500 mg of "Taurine" daily, vitamin D, pyrrosia leaf (Pyrrosia lingua), rhubarb (Rheum palmatum), Milk thistle, . ... are just some of the remedies that are suppose to aid your gallbladder in the process of dissolving Gallstones
(and preventing formation of new gallstones).
Eggs and Tofu are the rich source of lecithin.
Homoeopathy - A number of Homoeopathic remedies can be used to treat gallstone-related symptoms - Dioscorea, Colocynthis, or Belladonna, Berberis vulgaris, Hydrastis, or Chelidonium majus. You should consult a professional Homoeopath for exact medicine and dosages.

A mixture of essential oils has been shown to occasionally dissolve gallstones when taken for several months in uncontrolled studies. The greatest benefits occurred when the oils were combined with chenodeoxycholic acid, a prescription drug. However, only about 10% of people with gallstones have shown significant dissolution as a result of taking essential oils. The closest available product to what was used by these researchers is peppermint oil. Use of peppermint or any other essential oil to dissolve gallstones should only be attempted with the close supervision of a doctor.
One group of researchers reported that people who drink alcohol and take vitamin C supplements had only half the risk of gallstones when compared with other drinkers, though the apparent protective effect of vitamin C did not appear in non-drinkers.
In another trial, supplementation with vitamin C (500 mg taken four times per day for two weeks before gallbladder surgery) led to improvement in one parameter of gallstone risk (“nucleation time”), though there was no change in the relative level of cholesterol found in bile.

Other problem that may ocure is that stones are extremely irregularly shaped (Multi-bubbled surface - the surface of the stone is not smooth )
Look at those photos:
Irregular stones, but were expelled by flush procedure
Multi-bubbled surface stones
Barry's gallstone (cut in 3 parts)- very hard, 1 cm in diametar round protein/cholesterol stone with Multi-bubbled surface (pointing toward idea that stone was formed from hundreds of smaller stones - bubbles). Stone was taken out from surgically removed gallbladder. Barry did Liver Flush 8 times, and then, due to frequent attacks, decided to opt for surgery (open cholecistectomy).
In that case, it can be a serious problem for gallbladder to push the stones out even if stone is not very large.
To easily push the stone out, stones have to be "relatively small" or if large, their surface should be smooth.
Here are the photos of some of the "The largest gallstones" expelled by flushing.
Smooth stone will perfectly close bile ducts (or cystic duct) alowing bile pressure to rise to the point where bile pressure and movement of the ducts are strong enouh to push stones out.
Does that mean that there are people who will have to choose surgery, even if they do 20 flushes?
Yes and NO.
Some people will experience frequent attacks (like Barry) and will opt for surgery.
Great majority of people can achieve attack-free and symptoms-free life even if stones are still inside the gallbladder.
Regular fushing, healthy Diet
and healthy lifestyle, use of liver and gallbladder herbs, ... will prevent growth of existing stones, and will prevent creation of new stones and will flush those new created ... and will make it possible to live symptoms free life.
Then, after few months or 1 year or longer, stones may melt, or may gain some weight enough to become smuth and may, one by one, exit with regular flushing.
Or, stones will still be there ... nobody knows!
Look at the shape and size of hundreds of stones that actually came out with flush, and make your own conclusions...
