"Post operative advice"

My husband has recently had a kidney removed via keyhole surgery. The process from diagnosis to removal was very efficient and the care he received following the operation, whilst he was on the ward was also very thorough. Unfortunately the same level of information / care wasn't received on discharge from hospital. We were not given any literature to take home regarding any side effects of the operation. It has been nearly two weeks since the operation and he has had to return to a&e as he was unable to pass urine due to clots and also has a lot of blood in his urine still. This may well be very normal following kidney removal but as we were not given any post op advice on what to expect, this has caused a great deal of stress to my husband. Simple things such as how long before he can drive etc were not explained and had we been given More comprehensive information on recovery then we possible could have avoided the trip to a&e. A follow up appointment has been received for 5 weeks time with the surgeon but really feel that at the very least, we should have received an information leaflet on what to expect following the surgery.
