Made from natural plant ingredients, it gently helps you get rid of those pesky “little stones” inside your body.
In the urology department, a middle-aged patient sits pale-faced and sweating profusely. After reviewing the test results, the doctor says:
“It’s a kidney stone. Fortunately, it’s not too large — let’s try medication to help pass it.”
Then he hands the patient a box of a Japanese medicine called Ukuron.
A few weeks later, the patient returns with a smile:
“The stone actually passed!”
This medicine is widely used in Japan — so what makes it special?
Let’s take a closer look.
Urocalun Tablets 225mg – 100 Tablets
For Kidney Stones & Urinary Tract Stones | Non-Surgical Stone Treatment
What is Ukuron?
Ukuron is a medication developed by a major Japanese pharmaceutical company, specially designed to treat urinary tract stones. Its formula draws inspiration from traditional medicine and the use of natural plant-based ingredients.
It has been sold in Japan for decades and is commonly used by doctors to treat small to medium-sized kidney stones and ureteral stones.
Unlike strong chemical drugs, Ukuron relies mainly on natural plant extracts to gently improve the urinary system environment, helping the body naturally pass out the stones. This provides a non-surgical treatment option for many patients who wish to avoid invasive procedures.
Main Ingredient: The Power of Natural Plants
The key active ingredient in Ukuron is Quercus Salicina Extract Powder (also known in Japanese as ウラジロガシエキス).
Each tablet contains 225mg of this extract, which comes from the branches and leaves of a type of oak tree highly valued in traditional medicine.
In addition to the main ingredient, the tablet also contains several other components to help with absorption and tablet stability:
Lactose
Corn starch
Magnesium stearate
Talc
Hydroxypropyl methylcellulose (HPMC), etc.
The tablets are light yellow, oval-shaped, and moderately sized—easy to swallow.
How Does Ukuron Help Pass Stones?
Ukuron helps eliminate stones through several gentle but effective mechanisms:
✅ Prevents stone growth – inhibits crystals from aggregating into larger stones
✅ Helps dissolve certain types of stones – mild dissolving effect on some stones
✅ Reduces inflammation – soothes irritation caused by stone movement
✅ Increases urine output – promotes urination to flush out stones
Some studies suggest Ukuron is particularly effective for ureteral stones, though it also benefits patients with kidney stones. Clinical evaluations in Japan have shown it can be an effective aid in passing stones.

A: Many patients pass stones within 2 to 4 weeks, but it varies.
If there's no improvement after a month, or symptoms worsen, consult a doctor immediately.

Final Thoughts
Some Japanese urologists say Ukuron shows how herbal medicine can play a useful role in modern treatments, especially for patients with small stones.
As research into plant-based therapies continues to grow, traditional remedies like this are gaining renewed attention.
But always remember: consult your doctor before and during any kidney stone treatment.
Regular monitoring (such as ultrasound) is essential. Don't assume you're cured just because you're taking medication.
On the journey to treating kidney stones, Ukuron offers an important reminder:
You don’t always need aggressive treatment—gentle, natural options can also work.
