@tdgillett surgery, being laparoscopic, was an outpatient procedure. Hubby went home same night.
BTW, hubby is 73 when he had his surgery this past March.
This is info on RASP.
Robot-Assisted Simple Prostatectomy (RASP) is a minimally invasive surgical procedure used to treat severe urinary blockage caused by a very large prostate. It involves removing only the inner, blocking tissue of the prostate while leaving the outer capsule intact, and is distinct from a radical prostatectomy performed for cancer. Users on the Mayo Clinic Connect Discussion generally agree that RASP provides a durable, highly effective solution when non-invasive treatments or smaller procedures are insufficient for large prostates.

I will offer prayers for a good outcome no matter your choice.
Take care,
