During what procedure is a Van Buren dilator specifically used?

The Van Buren dilator is specifically designed for urethral dilation. This instrument consists of a tapered, cylindrical shape that allows for the gradual widening of the urethral passage. It is commonly utilized in urological procedures to treat strictures or obstructions by allowing for easier passage of instruments or fluids.

In the context of urethral dilation, the Van Buren dilator's design facilitates a controlled approach to enlarge the urethra without causing excessive trauma to the surrounding tissues. This method is particularly important in scenarios where a patient may have a narrowed urethra, which can lead to complications such as urinary retention or recurrent urinary tract infections.

While other procedures listed may involve various forms of dilation or the use of different instruments, the Van Buren dilator is distinctly associated with urethral dilation practices in urology, which is why this choice is correct.
