Here's some stuff that helped when I had the kidney done:
Things we did beforehand:
Hired retired nurse (our neighbor) to stay 2 days and first night at home to give wife a break.
Arranged for a neighbor meet us as soon as arrived home to help inside if needed, carry stuff in, etc.
Had several friends/neighbors alerted that they may be called if needed anything done.
Arranged phone tree with several friends and family members to relay phone calls sharing progress reports.
Set up recovery station at recliner prior to hospital, with every thing in reach (books, tablet, phone charger cables, kleenex, remotes, water, etc)
Set up drawer at bedside for meds and medical supplies prior to hospital
Prepared some meals and foods ahead of time, froze
Be sure pathways in house are clear of clutter and safe (especially if managing with walker)
Stuff we either had on hand already, or bought:
Urinal jars for bedside at home (amazon better quality & lid seal than take home from hospital)
Long handled silicone shower brush
Walker (stability walking first day or two, and great help getting up from toilet)
Electric lift chair (had from wife's knee replacement, but really helpful first 5 days) (Hard to get out of regular recliner, was able to easily start using regular on 6th or 7th day)
(Doctor might say that recliners are off-limits with back surgery. When renee had her knee done, manual recliner not allowed, but electric lift chair was OK)
Bought a couple of LED floor reading lamps (great for bed, because with remote control, did not have to reach and twist for switch on lamp)
Small pillow to hold against belly when coughing, sneezing, hiccups. Took to hospital.
