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 composed 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.
Homeopathy - 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.
Bach Flower Remedies - The flower essence most recommended for Gallstones is willow.
Herbs that relax the gall bladder and stimulate the bile are used in the treatment of gallstones.

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 occur 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 diameter 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) allowing bile pressure to rise to the point where bile pressure and movement of the ducts are strong enough 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 flushing, 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 smooth 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...
Chanca Piedra (Phyllanthus niruri, amarus)
The Spanish name of the plant, chanca piedra, means “stone breaker” or “shatter stone.” It was named for its effective use to generations of Amazonian indigenous peoples in eliminating gallstones and kidney stones. In Brazil, the plant is known as quebra-pedra or arranca-pedras (which also translates to “break-stone”). The plant is employed for numerous other conditions by the indigenous peoples, including blennorrhagia, colic, diabetes, malaria, dysentery, fever, flu, tumors, jaundice, vaginitis, and dyspepsia. Based on its long documented history of use in the region, the plant is considered analgesic and as an aperitif, carminative, digestive, emmenagogue, laxative, stomachic, tonic, and vermifuge.
Chanca piedra has a long history in herbal medicine systems in every tropical country where it grows. For the most part, it is employed for similar conditions worldwide. The natural remedy is usually just a standard infusion or weak decoction of the whole plant or its aerial parts. Its main uses are for many types of biliary and urinary conditions including kidney and gallbladder stones; for hepatitis, cold, flu, tuberculosis, and other viral infections; liver diseases and disorders including anemia, jaundice and liver cancer; and for bacterial infections such as cystitis, prostatitis, venereal diseases and urinary tract infections. It is also widely employed for diabetes and hypertension as well as for its diuretic, analgesic, stomachic, antispasmodic, febrifugal, and cell protective properties in many other conditions. It is little wonder that chanca piedra is used for so many purposes in herbal medicine systems: in clinical research over the years, the plant has demonstrated antihepatotoxic, antilithic, analgesic, hypotensive, antispasmodic, antiviral, antibacterial, diuretic, antimutagenic, and hypoglycemic activities.
Since the mid-1960s, chanca piedra has been the subject of much phytochemical research to determine the active constituents and their pharmacological activities. It is a rich source of phytochemicals, including many which have been found only in the Phyllanthus genus. Many of the “active” constituents are attributed to biologically active lignans, glycosides, flavonoids, alkaloids, ellagitannins, and phenylpropanoids found in the leaf, stem, and root of the plant. Common lipids, sterols, and flavonols also occur in the plant. Because of the confusion among P. niruri, P. amarus, and P. sellowianus over the years (and the reclassification of the genus), the research reviewed herein will encompass that which has been reported on all three of these very similar species.
The first notable area of study has validated chanca piedra’s longstanding traditional use for kidney stones. In 1990, the Paulista School of Medicine in São Paulo, Brazil, conducted studies with humans and rats with kidney stones. They were given a simple tea of chanca piedra for 1–3 months and it was reported that the tea promoted the elimination of stones. They also reported a significant increase in diuresis and sodium and creatine excretion. Subsequently the medical school educated new doctors about the ability to treat kidney stones with this natural remedy and now it is found in many pharmacies throughout Brazil. In a 1999 in vitro clinical study, a chanca piedra extract exhibited a potent and effective inhibitory effect on the formation of calcium oxalate crystals (the building blocks of most kidney stones). In a 2002 in vivo study, researchers seeded the bladders of rats with calcium oxalate crystals and treated them for 42 days with a water extract of chanca piedra. Their results indicated that chanca piedra “strongly inhibited the growth of the matrix calculus and reduced the number of stone satellites compared with the group receiving water.” Several of the animals even passed the stones which did form. Previously (in the mid-1980s) the antispasmodic activity of chanca piedra was reported. This led researchers to surmise that “smooth muscle relaxation within the urinary or biliary tract probably facilitates the expulsion of kidney or bladder calculi.” Researchers had already reported chanca piedra’s antispasmodic properties and smooth muscle relaxant properties (including a uterine relaxant effect) in earlier studies. In 1990, Nicole Maxwell reported that Dr. Wolfram Wiemann (of Nuremburg, Germany) treated over 100 kidney stone patients with chanca piedra obtained in Peru and found it to be 94% successful in eliminating stones within a week or two.
Chanca piedra is also used in herbal medicine for gallstones and, while no research has been performed that specifically validated this use, one study does indicate that chanca piedra has an effect on gallbladder processes. In a 2002 study, Indian researchers reported that chanca piedra increased bile acid secretion (demonstrated choleretic activity) and significantly lowered blood cholesterol levels in rats. The beneficial effects of lowering cholesterol and triglyceride levels was also confirmed by another in vivo (rat) study in 1985.
