Bladder cysts 3cm can be minimally invasive surgery, but if the bladder cyst does not cause ureteral obstruction and does not have any clinical symptoms, it is temporarily does not need surgical treatment, only need to be regularly reviewed. Bladder cysts are cystic lesions under the mucosa of the bladder wall, and usually have no clinical symptoms when they are small in size. Minimally invasive treatment of bladder cysts refers to cystoscopic decortication of bladder cysts. This procedure is less invasive, has a faster recovery, and has no effect on bladder function. It should be noted that not all bladder cysts require surgical treatment. Surgery is only needed if the cyst is too large and produces compression symptoms or affects the bladder capacity or the contraction of the bladder forcing muscle; if the bladder cyst is located near the ureteral orifice of the bladder and causes obstruction of the ureter; or if the bladder cyst leads to recurrent urinary tract infections. When a bladder cyst is detected, it is recommended to seek medical advice and follow the doctor’s instructions for disposal.
