Why don't doctors in Germany prescribe this drug? What are the risks of post cholesectamy syndrome and do those outweigh the risk of acute pancreatitis from leaving the stone in
The short version: the evidence for dissolving gallstones with drugs is weak, and the risk of leaving a stone in is real but often overstated.
The studies on ursodeoxycholic acid (UDCA) are old and small. A 1982 trial of 71 patients found that even at the highest dose, only 65% had partial or complete dissolution after 6 months, and stones over 10 mm dissolved in just 19% [5]. A 2025 cross-sectional study of 100 patients found complete dissolution in only 18% [1]. The recurrence rate is about 50% within 11 years [3]. These are not strong numbers for a drug that takes months to work.
Post-cholecystectomy syndrome is real. A 1980 study of 56 patients found that 71% had ampullary stenosis and 11% had retained common duct stones [7]. But the risk of acute pancreatitis from a retained stone is also real. Gallstones cause about 42% of acute pancreatitis cases worldwide [17]. The question is which risk is bigger for you.
| Outcome | Rate |
|---|---|
| Complete dissolution with UDCA | 18% [1] |
| Partial dissolution | 36% [1] |
| Recurrence within 11 years | 49% [3] |
| Post-cholecystectomy ampullary stenosis | 71% [7] |
| Gallstones as cause of pancreatitis | 42% [17] |
My call: for small, non-calcified stones in a functioning gallbladder, UDCA is a low-risk option with a modest success rate. The decision depends on your specific stone size and your tolerance for the uncertainty. Confidence: moderate.

Gallstone Dissolution after 6 Months of Ursodeoxycholic Acid (UDCA): Effectiveness of Different Doses
This trial of 71 gallstone patients found that higher UDCA doses (12 mg/kg/day) achieved higher dissolution rates (65%) than 4 mg/kg (33%) after 6 months, and smaller stones (<5mm) responded better (72%) than larger ones (>10mm, 19%).

A Combination of Chenodeoxycholic Acid and Ursodeoxycholic Acid Is More Effective Than Either Alone in Reducing Biliary Cholesterol Saturation
In a double-blind crossover trial of 18 gallstone patients, an equimolar combination of 5 mg/kg/day each of CDCA and UDCA reduced biliary cholesterol saturation index more than 10 mg/kg/day of either bile acid alone, with better tolerability.
