What should I pay attention to in my life after bladder tumor surgery? No matter transurethral resection or partial bladder resection, as long as the bladder exists, bladder tumor has the possibility of recurrence. Post-operative bladder drug infusion can effectively reduce the recurrence of tumor, but it cannot completely eliminate the recurrence of tumor. I will give you a very simple trick: drink more water and do not hold urine, so that the metabolic waste in the body can be discharged in time; quit smoking; minimize exposure to chemical hair dyes; review diligently: ultrasound is easy and painless but cannot detect small lesions, cystoscopy is uncomfortable but clear. If the problem is found, timely treatment can usually get good results. Ren Junkai, Department of Urology, Henan Cancer Hospital
