医生建议患者进行TURBT手术。TURBT全称“经尿道膀胱肿瘤电切术” 。
本动画展示了经尿道膀胱肿瘤电切术的手术过程，手术前，患者可全身麻醉，进入昏睡状态，或局部麻醉，仅将下半身部分麻醉。麻醉药起效后手术开始，手术时，医生会将学名为“电切镜”的细管子，通过尿道插入患者膀胱中，电切镜末端有电极刀头、光源及摄像头。电切镜通过患者尿道插入到膀胱中，有时需将肿瘤标记染色，以便于进行检查，这一过程叫做“光动力学诊断”（PDD）膀胱镜检查。这种诊断可检查其他方法无法检查到的肿瘤，若使用这种方法，需手术前一小时将染色剂注入膀胱中，染色剂会被肿瘤吸收，使其在蓝光下显出红色，如此可便于医生找到肿瘤的位置，随后，用电切刀头将肿瘤切掉，并在切除肿瘤的伤口周围电凝止血，将电切镜拔出，随后，将冲洗导管插入膀胱中，冲洗膀胱，防止血液凝块，导管顶端气囊充气，使之保持在固定位置，在出院之前，医生会将患者的导管拔出。

Your doctor has recommended that you undergo a TURBT procedure.TURBT stands for “Transurethral Resection of Bladder Tumour”.
This animation will show youhow a typical TURBT is performed.Before the surgery, you are either givena general anesthetic, which puts you to sleep,or a regional anesthesia, which numbsthe lower part of your body.The surgery will begin shortly afterthe anesthesia starts to work.During this procedure, a thin tubecalled a “resectoscope” is insertedthrough your urethra, then into your bladder.This resectoscope has a cutting tool,a light and a camera at the end.The resectoscope is inserted through your urethra,then into your bladder.In some cases, a dye may be usedto improve tumour detection.This is a procedure also known as“photodynamic diagnosis” (PDD) cystoscopy.It enables the surgeon to see tumoursthat might not be detected otherwise.If used, the dye is introduced into the bladderone hour before the operation.This dye is absorbed by the tumour,which makes it glow red under the blue light.The surgeon is now able to locatethe tumours more easily.A cutting tool is used to remove the tumour,then heat is applied on the surrounding areaof the tumour to stop the bleeding.Now the resectoscope is pulled out.Afterwards, an irrigation catheter will be inserted in your bladder.This is to flush the bladderand to prevent blood clots.The catheter remains in placeby inflating the balloon at its tip.The catheter will be removedbefore you leave the hospital.
