Introduction
Benign kidney tumors, such as renal hamartomas and renal lipomas, may invade the renal pelvis mucosa or compress the ureter during growth, leading to local microcirculatory disturbances and consequently causing hematuria. This situation is particularly evident when the tumor is large or ruptures, as tumor enlargement may compress the wall of the renal pelvis, or external forces may cause tumor rupture, subsequently resulting in vascular rupture and bleeding.

Under normal circumstances, benign kidney tumors may cause hematuria. If discomfort occurs, it is recommended to seek medical attention promptly. A detailed explanation is as follows:

Benign kidney tumors, such as renal hamartomas and renal lipomas, may invade the renal pelvis mucosa or compress the ureter during growth, leading to local microcirculation disturbances and resulting in hematuria. This situation is particularly evident when the tumor is large or ruptures, as tumor enlargement may compress the renal pelvic wall or lead to vascular rupture and bleeding due to external forces causing tumor rupture. Additionally, when benign tumors such as hamartomas grow excessively large and compress or even breach the renal pelvis, intratumoral bleeding can also lead to hematuria. Although benign kidney tumors may cause hematuria, not all benign kidney tumors will present with this symptom. It is recommended to undergo timely professional diagnosis and treatment.

Maintain a healthy diet, quit smoking, limit alcohol consumption, exercise moderately, avoid excessive fatigue, control body weight, and regularly monitor kidney function and disease progression.
