Urine flow is wavy

Abdominal aortic aneurysm, an arterial dilatation disease, is the most common type of aneurysm. In recent years, the incidence of abdominal aortic aneurysms in China has shown an upward trend. Statistics show that the incidence of abdominal aortic aneurysms is about 8.8% among the elderly over 65 years old. In addition, many patients will suddenly rupture aneurysms without any symptoms. The mortality of patients with such ruptured tumors can reach more than 90%. Therefore, the medical community also refers to abdominal aortic aneurysms as "time bombs" in the human body. Most patients with abdominal aortic aneurysms are asymptomatic, and they are often referred to as quiet abdominal aortic aneurysms during routine physical examinations. With the development of regular physical examinations, this type of aneurysms has also gradually increased in symptomatic patients. The common symptoms are abdominal pulsatile mass, followed by dull pain around the umbilicus or upper abdomen or only abdominal discomfort. When the aneurysm invades the lumbar spine, there may be pain in the lumbosacral region. Sometimes the aneurysm increases and can even penetrate the duodenum or jejunum, resulting in the appearance of gastrointestinal bleeding. In addition, the enlargement of the tumor may produce some compression symptoms such as oppression of the gall bladder. Common jaundice appears; oppression of the duodenum causes intestinal obstruction; compression of the ureter causes renal colic or hematuria; compression of the bladder may cause frequent urination and fluctuating urine flow. The pattern of urination should normally be a smooth bell shape, which smoothly reaches the maximum urine flow rate and is smoothly resolved. When the urination is difficult, sometimes it will be interrupted, and the graph will appear wavy. Some people will use the abdominal force to see the jagged shape. These can provide doctors with a diagnosis.
