The most common complications after prostatectomy include hematuria, pain, urinary tract infection, and dilutional hyponatremia. 1. Hematuria: Prostatectomy can lead to the phenomenon of postoperative bleeding and hematuria due to damage to the blood vessels around the prostate. 2. Pain: If the surgery removes too much, postoperative pain and other discomforts can be triggered. 3. Urinary tract infection: If the operation is not strictly aseptic, it is easy to cause infection of the urethra after the operation, triggering symptoms such as urinary urgency and dysuria. 4. Dilutional hyponatremia: postoperative hyponatremia can also be triggered, leading to dizziness, nausea and other discomforts. If you experience discomfort after prostatectomy, please seek medical attention promptly.
