Early symptoms of urinary system tumors

There are no specific symptoms in the early stage of urinary system tumors. Symptoms that may be shown include: 1. Pain at the site of the tumor, such as low back pain, pain in the ureter, pain in the lower abdomen, pain in the external genitals, etc. Pain is mild at first, intermittent or occasional. When the tumor volume further increases, it can be manifested as persistent pain. 2. Macroscopic hematuria, when the tumor gradually grows and destroys surrounding tissues, can lead to bleeding. The patient can show transient gross hematuria, generally without any pain and urinary tract irritation symptoms. When the tumor progresses further, it will show persistent gross hematuria. 3. Symptoms of local obstruction. When the urinary system tumor occurs, it can lead to poor urine drainage and lead to local obstruction. Manifestations include kidney hydrops, ureteral dilatation, poor urination, and adverse urination. 4. Symptoms complicated by tumor, such as diet loss, weight loss, fatigue, weakness, listlessness, etc.
