What is the cause of the lump in the lower right abdomen?

If there is a lump in the lower right abdomen, we need to pay attention to understand the cause, because some are physiological, while others may be caused by urinary tract obstruction or inflammation. Do not blindly treat it with medication.

1. Physiological "lumps" are not real diseases, but are sometimes mistaken for pathological masses. In addition to the uterus, bladder, and fecal masses, the muscles between the well-developed rectus abdominis tendons, the spine or sacral promontory in emaciation, and the spontaneously spasmodic intestines may all be misdiagnosed as pathological. Even the abdominal aorta of a person with a soft or weak abdominal wall may be mistaken for a "pulsating mass."

2. Obstructive masses Obstructive masses in the gastrointestinal tract can cause abdominal pain, bloating, vomiting, or constipation without flatus; masses obstructing the bile duct cause painless jaundice, generally without fever; masses obstructing the urinary tract often cause distension and pain in the lower back. Strictly speaking, congestive splenomegaly and cholestatic hepatomegaly are also obstructive masses.

3. Inflammatory masses are often accompanied by inflammatory signs such as fever, local pain, and increased white blood cell count. Such as periappendicitis mass, mesenteric lymph node tuberculosis, perirenal abscess, etc.

4. Cystic masses are mostly round or oval in shape, with a smooth surface and a sense of fluctuation. Common ones include congenital polycystic liver, polycystic kidney, urachal cyst; retention pancreatic cyst, hydronephrosis; tumorous ovarian cyst; inflammatory gallbladder effusion, hydrosalpinx, encapsulated effusion; parasitic hydatid cyst, etc.

5. Tumorous masses are mostly solid masses. Malignant tumors account for the majority, and are characterized by rapid development, accompanied by anemia, weight loss and cachexia in the late stage; benign tumors have a long history, are larger, smoother, and have a certain degree of mobility.

6. Traumatic masses such as splenic rupture hematoma in the left upper abdomen, pancreatic pseudocyst in the upper abdomen, retroperitoneal hematoma in the lower abdomen or pelvic cavity, etc. See Abdominal Trauma.
