What are the symptoms of idiopathic retroperitoneal fibrosis? Briefly described as follows:
1、The early symptoms of idiopathic retroperitoneal fibrosis (RPF) are insidious, mainly manifested as non-specific back pain, abdominal pain, and side pain, presenting as persistent dull pain or hidden pain, which can occur at any age, even in newborns, but it is more common in middle-aged people, and male patients are more than female patients2倍,Caucasians and Africans can all be affected. The disease usually starts insidiously, with a long course, and diagnosis is often made several months or even years after the appearance of some vague symptoms, with pain being the most common and also the earliest symptom, usually felt as dull pain or discomfort in the lower lateral abdomen, lumbosacral region, or lower abdomen; other symptoms include anorexia, weight loss, and fatigue, with possible unilateral or bilateral leg swelling, scrotal swelling or moderate fever, and occasionally palpable masses in the abdomen or pelvis.
2、In the clinical manifestations of advanced stages, it is often the symptoms of compression or involvement of adjacent organs, such as causing ureteral stenosis can lead to proximal infection or dilation, which can produce lumbar or costovertebral angle pain, frequent urination, and increased nocturia; compression of both ureters can suddenly cause anuria; due to frequent hydronephrosis or kidney infection, lumbar tenderness is very common; hypertension is common (one of the causes of headache), mostly due to renal obstruction, because with the rupture of the ureter, after the decompression operation or resection of the non-functional kidney, blood pressure can return to normal, gastrointestinal symptoms may be related to uremia or direct damage to the gastrointestinal tract (such as displaced stenosis).
3、There have been reports of bile duct and pancreatic duct stenosis, if involving the portal vein or splenic vein, it can lead to portal hypertension, esophageal varices, and ascites; due to fibrosis, retroperitoneal or mesenteric lymphatic drainage is obstructed, which can also cause protein-losing enteropathy or malabsorption; compression or obstruction of retroperitoneal lymph, veins, or small arteries can cause unilateral or bilateral leg swelling, penile swelling or scrotal edema, even abdominal wall veins become full or varicose, thrombosis of the lower extremities, weak pulses at the distal end of the lower extremities, intermittent claudication, and may be accompanied by fibrosis in other parts (such as mediastinal bile ducts), even硬化性胆管炎, Peyronie's disease (Peyronie's disease, penile cavernosal fibrosis, causing fibrous painful penile erection, i.e., fibrous cavernitis) and other diseases.
4、体格检查时,下腹部及腰部常有压痛,肾区可有叩击痛或触及肿大肾脏,腹膜后纤维瘢块一般不易触及,可伴有高血压。
