Jacey - I hope you're reassured by fellow-posters who've gone down the robotic LRP route. I had my encounter with the robot six weeks ago - see the Da Vinci thread on this forum - & this was my first GA since a childhood tonsillectomy. The weeks of waiting & psych-ing myself up for the op had me champing at the bit somewhat, but once in theatre I was immediately reassured by the friendly & laid-back approach of the anaesthetists at my local hospital. Apart from a slight sore throat I had no post-op pain, & only mild discomfort from the catheter when sitting. Bear this in mind on your long-ish car journey home & equip yourself with a variety of cushions. By the way, this discomfort will magically disappear when your catheter is removed. At home I found that leg & night-bags were no problem once I got used to them, but fear of infection kept me to a strict ritual of steri-swabbing the nozzles when changing & emptying bags.
Regarding anti-DVT compression stockings - do take extreme care when putting them on. I'm a stone-&-a-half over my ideal weight - I'm 61, by the way - & I ricked my back quite badly just before being trundled in to meet the robot, so was bizarrely grateful for the pre-op spinal injection ! Post-op I received Clexane and had a pneumatic massaging-machine attached to my calves for the first 24 hours or so, but wasn't offered any thinning shots for self-medication at home. Hospitals differ on their post-op routines, but make sure your discharge nurse gives you enough sterile swabs & dressings to manage the small port-wounds until the closures are removed, especially if you're not scheduled to have a visit from a district nurse. We were also given alcohol hand gel and surgical gloves, a staple-removal kit to take to our GP nurse, plus an informative incontinence & ED starter-pack from P Ca UK. Six weeks on & continence is slowly improving - pelvic exercises adhered-to rigidly.
My GP obligingly prescribed Viagra, which RP patients are eligible to enjoy free on the NHS, regardless of age. I haven't used it yet, but live in hope...
Good luck & all the best for the op, & for a quick recovery !
