Which needle is used during the bladder suspension procedure for treating stress incontinence in women?

1. Stamey

2. Chiba

3. Dorsey

4. Tru Cut

The correct answer is: Stamey

The Stamey needle is specialized for use in bladder suspension procedures, particularly for treating stress incontinence in women. This procedure involves the placement of sutures through the mid-urethra to support the bladder neck, and the Stamey needle's design allows for accurate placement of these sutures. Its unique structure facilitates passing the suture through the vaginal wall and surrounding tissues, providing the necessary support to the bladder. Other types of needles, such as the Chiba needle, are typically used for sampling or drainage in other medical contexts and not specifically for bladder suspension. The Dorsey needle is often utilized in different surgical procedures, including those involving other organ systems, while the Tru-Cut needle is primarily used for biopsy procedures to obtain tissue samples. Hence, their designs and intended uses differ significantly from that of the Stamey needle, which is tailored for bladder suspension surgeries.
