Minimally invasive resection of right kidney cancer for 9 years and constant pain in right lower abdomen may be caused by wound pulling, bacterial infection or recurrence of the disease. 1. Wound pulling: After some right kidney cancer patients choose minimally invasive surgery, when they do strenuous exercise in daily life, it may lead to wound pulling and poor recovery of the wound area, which may cause the symptom of hidden pain in the right lower abdomen. 2. Bacterial infection: repeated bacterial infection in the surgical wound site can induce inflammation, which can also lead to the symptom of constant pain in the lower right abdomen, accompanied by redness and swelling around the wound and burning sensation. 3. Recurrence: After minimally invasive resection surgery, some patients may suffer from recurrence of the disease, which can be induced by the pressure of tumor and the symptom of total pain in right lower abdomen. Minimally invasive resection of right kidney cancer for 9 years may also be caused by other reasons, such as ureteral stones, etc. They should go to regular hospitals in time to clarify the cause of the disease and choose suitable treatment methods.
