Clinical manifestations of kidney stones in children

Specific reasons for the formation of kidney stones are not fully understood, but genetics, diet and drinking water composition. Children, low incidence of kidney stones, kidney stones are more common primary, general information 60% to 80%, 1% of hereditary disease, uric acid stones account for 5% to 39%, 5% high-calcium state. Differences in the incidence of large numbers of different ages, children are rare but the incidence increases with age.

Usually after the age of onset of 4 to 5, 8 to 10 is more common after the age of 3-4 year old. The group of 25 patients, 1 of 7 cases of 7 years, 8 years old in 17 cases (68.0%), only 1 case of 5 month baby.

Children with atypical clinical manifestations of kidney stones, mainly hematuria, nausea, vomiting, abdominal pain, children account for ambiguity, low back pain position statement is unclear. Group 1 patients with kidney stones in children 5 years old, each episode tells the left upper abdominal pain.

Therefore, the clinical diagnosis of kidney stones first little longer most easily misdiagnosed. To have low back pain and or hematuria preferred B-mode ultrasound, combined with abdominal X-ray film can improve the diagnostic rate; diagnosed therapy to medicine penetration to blood circulation, the primary purpose of expansion of blood vessels, urethral smooth muscle to improve the local blood supply, rich blood flow to the kidneys to produce urine increased, is conducive to stone discharge.

Expansion of the renal artery damage to the kidneys to increase the effective blood perfusion, increased oxygen supply to the kidneys and improving kidney microcirculation, adjust the overall function of the kidneys, the urine pH stability, so that Ca2 +, lipid, oxalate and other fully dissolved in urine, not deposition, no precipitation, the formation of stones is not nuclear, then generate the conditions for the eradication of the stone. Stones greater than 0.80cm × 0.90cm, line drug treatment in vitro with laser lithotripsy, laser lithotripsy for the treatment of kidney stones in vitro a better way, should be strictly controlled indications.
