Flexible Cystoscopy: Indications & What to Expect

最后更新： 2026年4月29日

另一项患者要求较多的服务是 "柔性膀胱镜检查"。在谈这个问题之前，我们先来了解一下它的历史。1878 年，卡尔-弗里德里希-尼采和莱特发明了第一台真正意义上的功能性膀胱镜，当时它被称为 "刚性膀胱镜"，其形状是实心的，不能根据尿道解剖结构弯曲，因此在清醒的病人身上进行刚性膀胱镜检查时非常痛苦。

因此，随着光纤技术的成熟，1973 年津志田（Tsushida）和菅原（Sugawara）发明了柔性膀胱镜。柔性膀胱镜的直径较小（如吸管大小），能根据尿道的解剖结构弯曲，减少了不适感，因此在病人清醒的情况下，使用尿道止痛凝胶进行局部麻醉时，很容易进入膀胱。

柔性膀胱镜检查可沿尿道弯曲

常见问题解答

Q1: What is flexible cystoscopy and how is it different from rigid cystoscopy?

Flexible cystoscopy uses a thin, flexible scope that curves along the natural anatomy of the urethra, allowing examination of the bladder and urethra under local anesthesia in awake patients. Unlike rigid cystoscopy, which cannot bend and causes significant discomfort, flexible cystoscopy is well-tolerated and can be completed within 5 minutes by an experienced urologist.

Q2: What are the main indications for flexible cystoscopy?

Flexible cystoscopy is indicated for surveillance of the bladder and urethra for abnormal lesions, evaluation of bloody urination or voiding dysfunction, diagnosis of urethral or bladder neck stricture, ureteral stent removal, and intraoperative assessment to facilitate ureteroscopy. It is also used to evaluate fistulas and congenital anomalies.

Q3: Is flexible cystoscopy painful?

Flexible cystoscopy is generally well-tolerated with minimal discomfort. Before the procedure, the urologist applies anesthetic lubricating gel inside the urethra for approximately 10 minutes to reduce pain. The flexible scope follows the natural curve of the urethra, making it far more comfortable than rigid cystoscopy. Most patients tolerate the entire procedure with only mild discomfort.

Q4: How should I prepare for flexible cystoscopy?

Before flexible cystoscopy, inform your urologist of all current medications, especially blood thinners, as these may need to be temporarily stopped to reduce bleeding risk. No special diet preparation is required. The procedure is performed as an outpatient under local anesthesia, so you can typically return home the same day.

Q5: What happens after flexible cystoscopy?

After flexible cystoscopy, your urologist will review the findings and discuss the next management steps. You will be prescribed oral antibiotics for several days to prevent urinary tract infection, along with pain relief if needed. Mild urinary discomfort or light bloody urination may occur for a short time after the procedure.
