Hi!welcome to Chat Doctor! For early stage or superficial bladder cancers, transurethral resection of the bladder tumor (TURBO), is the most common treatment. This surgery is done through an instrument passed up the urethra, The side effects of transurethral bladder surgery are generally mild and do not usually last long. Unfortunately, even with successful treatment, bladder cancer often recurs (comes back) in other parts of the bladder. If transurethral resection needs to be repeated many times, the bladder can become Weak, scarred and lose its capacity to hold much urine. This can be the reason in your case too. You must discuss with your treating urologist clearly. Hope this helps!
