Hematuria and blood clots in urine after surgery for renal staggered tumor may be due to normal blood seepage from the surgical wound, poor surgical hemostasis after bleeding, etc. If the bleeding is large, it is recommended to consult a doctor. Most of the renal stromal tumors are benign, if there is no obvious symptom, it is enough to follow the diagnosis and regular review. For the progressive increase in the size of the stromal tumor requires surgical treatment, and the surgery is mostly laparoscopic or robot-assisted lesion excision, and it is normal to have wound bleeding, hematuria and blood clots within a short period of time during the surgery, which is not a cause for concern. If the renal stenoma rupture and bleeding occurs, it is more serious, and vascular intervention surgery is feasible to block the bleeding. If hematuria or blood clots in urine still exists after the surgery, it may be a manifestation of poor therapeutic effect, and further nephrectomy treatment may be required. It is recommended to go to the hospital in time for examination and early treatment of hematuria and blood clots in urine after renal stenoma surgery.
