Abstract

Introduction. The most reliable method for bladder catheterization when necessary is to put a urethral catheter under visual control. However, this requires endoscopic equipment and transportation of patient to a cystoscopy unit or operating room, which is not always possible. To solve these problems, we have developed the optical urethral catheter Visus MG.

Aim. To evaluate the safety and efficacy of a new optical urethral catheter with a portable endoscopic complex.

Materials and methods. The prospective single-center clinical study included men, in whom the first bladder catheterization with a soft urethral catheter was impossible. They underwent insertion of the optical urethral Visus MG catheter under visual control.

Results. A total of 60 men were included in the study. The median age was 70 years, the average prostate volume was 40 cc. Successful repeated catheterization was performed in 57/60 (95%) patients. In 5% cases (n=3), bladder catheterization was unsuccessful due to urethral obliteration.

In 53 (88.3%) men, various surgical methods or manipulations were previously performed, including temporary bladder catheterization in most cases (n=16; 30.7%). The cause of failure of primary catheterization were urethral strictures in 19 (31.7%), benign prostatic hyperplasia in 9 (15%), false passage in 10 (16.7%), bladder neck sclerosis in 10 (16.7%), urethal obliteration in 3 (5%), and the foreign body in the urethra in 1 case (1.7%). In 6 (10%) men, there were signs of iatrogenic urethral trauma with urethrorrhagia due to previous attempts of catheterization, which, however, did not prevent a placement of the urethral catheter under vision control in safe manner.

Conclusion. Bladder catheterization with an optical urethral catheter Visus MG with a portable endoscopic complex was successful in 57/60 (95%) patients after failed primary catheterization, which indicates the high efficiency of the method. The advantages of the technology are its portability, mobility and direct visualization of the urethra.
