Why can hematuria have after kidney stone operation

summary

For some large renal calculi, it often causes severe pain in patients, and the general drug treatment of large calculi is difficult to work, so most patients with large renal calculi will choose surgery to treat, and the choice of surgery is more extracorporeal lithotripsy. Although this therapy can't remove the stones all at once, with drinking water, exercise or stone removing drugs, the small stones will be discharged slowly. After treatment, some patients may also have some abnormalities, such as hematuria. So what causes this? Is it normal? Here is the answer.

Why can hematuria have after kidney stone operation

Hematuria after kidney stone lithotripsy is mainly because small stones will be discharged from the body after stone lithotripsy. At this time, in the process of removing stones, stones will inevitably scratch the urinary tract and other urinary pipes. When scratched, patients will have hematuria, which will be accompanied by pain. Therefore, hematuria after kidney stone lithotripsy is normal.

In a short period of time after the treatment of general renal calculi, hematuria is mainly caused by the stimulation of the inner surface of the renal pelvis and ureter when the stones are discharged. This kind of hematuria often occurs in bursts and does not exist for a long time. Slowly, with the discharge of the stones, hematuria will disappear, so there is no need to worry too much.

Of course, if the patient's stones are completely discharged after surgical treatment, and then hematuria occurs, it may be the recurrence of stones. When the recurrent stones are stuck in the kidney and ureter, the edge of the stones will rub against the mucosa of the pipe, which will damage the mucosa, and the submucosal blood pipe will also be damaged and ruptured, so that the blood will be discharged with urine, causing hematuria.

matters needing attention

In order to be more assured, it is suggested that hematuria after kidney stone surgery should be reviewed in time. Generally, ultrasound and hematuria routine examination can make a definite diagnosis. Especially if accompanied by obvious pain or discomfort, more attention should be paid to timely review.
