Most people have no issues with voiding after a sling procedure. However, it's not unusual to have some difficulty voiding temporarily after surgery, and possibly needing to have a catheter or learn to catheterize yourself for a short time. In general, most people are back to having normal voiding patterns within six weeks or so.

In particular, note where Dr. Sobol writes:
"Following suit with the minimally invasive type of slings that women have been able to enjoy recently, there is now the trans-obturator sling for men. The incision is similar to that for the older sling but the procedure involves only placing a mesh-like material against the urethra to increase resistance. The complication rate is pretty low, and the procedure itself is easier for the surgeon. The results are comparable or better to the older sling that used bone anchors."
