 [ Symptoms ] is a bladder sling used for lumbar fusion surgery  i think i remember my surgeon saying he used a sling to keep it out of the way when working on the cage damn drugs my mind was a haze [ Disease ] well your best bet honestly is to contact your surgeon is office and ask them directly they can look the information up in your chart but i can tell you that bladder sling is a term normally used regarding bladder suspension surgery in women with prolapsed bladders a bladder sling restores the urinary bladder to its correct position within the pelvic cavity men with urinary incontinence after prostatectomy may also have bladder sling surgery  in lumbar fusion surgery the approach normally is from the back did you lie face down for your surgery  the abdominal cavity is never entered so the positioning of your bladder is of no consequence you likely did have a foley catheter inserted to drain your bladder for your comfort during surgery but this probably was removed before you even woke up from surgery i hope this helps
