I had my prostate out in late March 2018. When my catheter was removed a week later I had no bladder control. I was not given any warning of what to expect or how to prepare. I had brought pads with me (the hospital did not offer any). I leaked very badly going home, fortunately the bus seats were not porous. I should have been wearing incontinence pants. When I bought some pants the largest available did not fit (I am 38" waist) they felt like they were constantly falling down and there was no obvious difference between front and back.
After 2 weeks I was getting nowhere and I needed to be back at work by the end of April. I persuaded my GP to prescribe a sheath catheter and leg bag which I used until July 2018. (They had to be obtained via an on-line pharmacy. Fortunately I was not on any other medication.)
While using the sheath and leg pag (and a pad in case of leakage) I did pelvic floor exercises, squeezing a rubber ring between my thighs. I was soon able to use the pad at night. after 3 months I was able to dispense with the sheath and leg bag.
I think it was October 2023 when found I only had a slight persistent drip and I could get by with a face cloth inside my pants.
I can still leak badly if I sweat intensely, and I urinate very frequently, but I am mostly back to normal.
