Post-operative care after transurethral bladder tumor electrosurgery is primarily for the urinary catheter, which, unlike a typical open procedure, does not have a wound. If a wound exists, general wound care is more complex. Transurethral bladder electrosurgery, a minimally invasive surgery, has no open incision, but there exists a urinary catheter, so most of the general symptoms of discomfort are caused by urinary catheter infection. The care of the urinary catheter is the post-operative care for bladder tumor electrosurgery, such as urinary catheter cleaning. If there is more secretion, the frequency of cleaning should be increased, and if urine or blood flows out, it needs to be cleaned in time. Also observe whether the urinary catheter is blocked or not, if blocked bladder will be distended and painful, the urinary catheter needs to be unblocked in time. After surgery, there may be blood clots and necrotic tissues that cause residues inside the bladder to block the urinary catheter, and it is necessary to pay attention to whether the bladder and urinary catheter are blocked during care. In addition, if urinary tract infection occurs, the infection will cause discomfort in the lower abdomen and cause hematuria and cloudy urine, and the relevant content should be observed and treated accordingly.
