What are the symptoms of kidney calculi's attack?

Kidney calculi's symptoms can be divided into colic and hematuria, as follows:

1, colic The pain caused by kidney calculi can be divided into dull pain and colic. 40%-50% patients have a history of intermittent pain. Pain is often located in the waist and abdomen, mostly paroxysmal or persistent. Some pain may only be manifested as waist pain and discomfort, and activity or labor can promote the onset or aggravation of pain. Kidney calculi's colic is a severe knife-like pain, which often happens suddenly. Pain often radiates to the lower abdomen, groin or inner thigh, and to the labia in women. During the onset of renal colic, the patient showed acute symptoms, curled up in bed, pressed his abdomen or waist with his hand, and even rolled on the bed, moaning. The attack usually lasts for several hours, but it can also be relieved within a few minutes. When renal colic is severe, the patient is pale, sweating all over, rapid pulse and even blood pressure drop, showing a state of collapse, accompanied by nausea, vomiting, abdominal distension and constipation. Urine volume decreases when colic attacks, and polyuria may occur after colic is relieved.

2, hematuria. Hematuria is another major symptom of kidney calculi. Pain is often accompanied by gross hematuria or microscopic hematuria, the latter is mostly, and a large amount of gross hematuria is rare, which can be aggravated after physical activity. Patients in kidney calculi can excrete sand and stones from their urine, especially when they suffer from pain and hematuria. When stones pass through the urethra, they will block or sting. The common complications in kidney calculi are obstruction and infection, and many cases seek medical treatment because of symptoms of urinary tract infection. Obstruction can lead to hydronephrosis and a lump in the upper abdomen or waist.
