Early symptoms of renal pelvic carcinoma?

summary

Renal pelvic carcinoma is a kind of tumor that occurs in the epithelium of renal pelvis or calyces, accounting for about 10% of all renal tumors. Interstitial nephritis, long-term use of analgesics, chronic inflammation or stone stimulation, contact with carcinogens are often the causes of renal pelvic tumors. Most of the patients were over 40 years old. The ratio of male to female was about 3 ∶ 1. There was no significant difference between the two sides of the disease. About 2-4% of the patients had both sides at the same time. Because of the thin wall of the renal pelvis and abundant lymphoid tissue around it, the tumor is easy to metastasize to the paraaortic and cervical lymph nodes; The main organs of hematogenous metastasis are lung, liver and bone. Let's talk about the early symptoms of renal pelvis cancer.

Early symptoms of renal pelvic carcinoma?

About 70-90% of the patients presented with painless gross hematuria in the early stage. A small number of patients with tumor obstruction at the junction of the renal pelvis and ureter may cause lumbar discomfort, dull pain and distending pain. Occasionally, renal colic may be caused by blood clots or tumor shedding. It is rare to have lumbar mass due to tumor growth or obstruction, There are still a small number of patients with urinary tract irritation symptoms. Anemia and cachexia occurred in late stage patients.

The incidence of hematuria is about 90%, which is characterized by intermittent, painless, naked eye, whole course hematuria, and can discharge cord blood clots. When painful hematuria, ureteral obstruction caused by blood clot can cause renal colic, and hydronephrosis caused by tumor can cause waist pain and discomfort.

Most of the tumors were located in the waist or upper abdomen. The appearance of the mass indicates that the tumor obstruction leads to hydronephrosis or the disease is near advanced stage. General symptoms, general discomfort, loss of appetite and weight loss are common symptoms of tumor patients. Some patients may also have fever, anemia or hypertension in varying degrees.

matters needing attention

Patients with the above clinical manifestations and signs should consider the possibility of renal pelvis tumor. Combined with laboratory examination, cytology and imaging, the diagnosis can be confirmed.
