Urolithiasis - Science topic

It sounds like you're conducting an interesting experiment! To measure any increase in volume caused by plant extracts, you might consider using imaging techniques like ultrasound or CT scans. To measure the actual stone size formed by Ethylene Glycol (EG), methods like microscopy or imaging can help assess stone dimensions. Consider collaborating with experts for precise techniques in this field. For more details contacting…

That laser is readily available in veterinary medicine and has been used in human medicine for lithotripsy occasionally.

Dear Konstantin,

Please check the following resources.

Chemical analysis is the only way to confirm. However, a simple kub x-ray can differentiate radio opeque from radioludcent one. Non contrast ct scan, urin analysis and blood chemistry may give some clue.

you can use Yawi3D, a plugin of ImageJ. ImageJ and Yawi3D are open source, freeware, multipatform, based on Java 

Yes, you are right; however it is very expensive, and it is impossible to have in our department.

we perform the puncture without moving the C-arm (in a fixed position), with the X-ray beam perpendicular to the tract. This model give us the same thing and I have used it in many small workshops and the urologist were confident to start puncture and even, some were quicker to perform their first real puncture.

The supersaturation of urine with CaOX, the most common component of kidney stones is an important factor in crystallization, with later factors being nucleation, growth and aggregation. Thus if supersaturation or later steps in crystallization can be prevented, then lithiasis should be avoided. Indeed, several measures are usually taken to reduce supersaturation, e.g. increasing fluid intake and medical therapy. Although treatments have improved considerably, it is generally accepted that better strategies for preventing kidney stones have developed.

Dear Mudhir, it is easy to induce kidney stones in rats by adding ethylene glycol to the drinking water or by administering intraperitoneal calcitriol in low dose. I have used both methods in my investigation, using adult Wistar rats, and all the animals developed kidney calculi after two to four weeks. However, many animals also presented kidney failure and some died during treatment. More important, most animals presented a heavy burden of crystals within renal tubules. Therefore, I believe that this method does not reproduce accurately what happens in human kidney disease.

24 hour urine should be kept in refrigerator or long preservation and sodium azide is generally used to prevent any bacterial and fungal growth in it

I would recommend pressure/flow study to determine if he is obstructed even with high flow rate, specially if he has high residual urine. Ultimately he may need bladder outlet reduction procedure plus cystolithotripsy. My preference would be Prostate Photovaporization and Holmium laser lithotripsy.
