"Lack of communication and involvement of the..."

Due to strong abdominal pain, I went to the emergency station on a Saturday early morning for treatment. I got to see a doctor about two hours after the first contact with the nurse and pain treatment, which was adequate. The ER doctor performed the essential tests and I got a CT Scan. Then the whole process slowed down and only later in the afternoon, I briefly were informed that the CT Scan revealed two kidney stones. When I asked what happens next, I only got very unspecific information and was told that I should stay in the hospital and eventually ('possibly') will get surgery on Monday. On Sunday the pain was gone and I asked if I can see a doctor to get more information on the next steps. Only late in the afternoon, a team of doctors stopped by briefly to say that the kidney stone may have been flushed out by the liquid infusion but I should stay another night anyway. It seems this hospital wants to fill its beds and is not considering the actual condition of the patient. This I find is highly annoying and leaves me with a bad impression; there is either a lack of proper policies in place or simply no culture for listening to a patient.
