kidney crystals

Introduction

Introduction Kidney crystallization is a precursor to kidney stones and is closely related to diet.

Cause

Cause

1, too much oxalic acid accumulation

The accumulation of oxalic acid in the body is one of the factors leading to kidney urinary stones. Such things as spinach, beans, grapes, cocoa, tea, oranges, tomatoes, potatoes, plums, bamboo shoots, etc., which people generally like, are foods with higher oxalic acid. The doctor found through research that 200 grams of spinach contains 725.6 mg of oxalic acid. If one person eats 200 grams of spinach at a time. Some foods are prone to stone loss. After 8 hours of eating, the urine oxalic acid excretion is 20-25 mg, which is equivalent to the average total amount of oxalic acid discharged by normal people in 24 hours.

2, metabolic disorders

Animal viscera, seafood, peanuts, beans, spinach, etc., all contain more bismuth ingredients. After entering the body, the metabolism is carried out, and the final product of its metabolism is uric acid. Uric acid promotes the precipitation of oxalate in the urine. If, too much, the food rich in sputum is consumed too much, the metabolism of sputum is abnormal, and oxalate is deposited in the urine to form urinary stones.

Examine

an examination

Urinary sediment crystallization examination retrograde pyelography

Laboratory inspection:

Urine tests can be divided into general and special tests:

(1) The general examination is mainly urine: it includes pH, relative density (specific gravity), red blood cells, pus cells, proteins, sugar, crystals, etc. Hematuria, crystal urine and pus cells can be found in the urine of patients with uroliths. The pH value often indicates certain types of stones: calcium phosphate, the pH value of patients with carbonate apatite stones is often higher than 7.0; while the urine pH of patients with uric acid, cystine and calcium oxalate stones is often less than 5.5, visible Microscopic hematuria or gross hematuria, but 15% of patients have no hematuria. In non-infectious stones, there may be mild pyuria.

(2) Special inspections include:

1 urine crystallization check: fresh urine should be retained, if you see benzene-like cystine crystals suggest that there may be cystine stones; such as urine found in uric acid crystals, often suggest uric acid stones; found that the envelope-like crystal may be two Calcium oxalate stone; coffin cover crystal is magnesium ammonium phosphate crystal; sulfonamide crystals are found in the urine of patients suspected of having sulfa drug stones.

Diagnosis

Differential diagnosis

It can be identified by kidney stones.

A calculus of kidney is a stone that occurs in the renal pelvis, renal pelvis, and junction of the renal pelvis and ureter.
