What is the anatomic difference between retropubic and transobturator midurethral slings in terms of their path to provide support?

Explanation:
The path that the sling takes to support the urethra is what distinguishes the two approaches. A retropubic sling travels upward behind the pubic symphysis, exiting through a suprapubic route, so the tape sits behind the pubic bone to provide vertical support under the urethra. A transobturator sling, by contrast, exits laterally through the obturator foramen, running to the groin/inner thigh region, so its path is through the obturator canal rather than behind the pubic bone. Neither sling traverses the bladder.
