Lack of Medical Care during lockdown

My son has bladder stones. He was diagnosed in January at Estcourt Hospital, where there is no urology department. He had to wait two months to get an appointment with a urologist at Ladysmith Hospital because they said "it wasn't an emergency." This took us into lockdown. I got permits to go to Ladysmith Hospital. My son was told he needed an operation, but couldn't have one straight away because of Covid 19 and "it wasn't an emergency." Four months later he is still waiting to be called for his operation, which will take about half an hour and requires no overnight stay in the hospital. He is in almost constant agony and is peeing clots of blood. He is going to end up with permanent problems because "it is not an emergency." Unlike kidney stones, these cannot be dissolved. He cannot work because of the pain and I am a pensioner so we cannot afford private medical care. What are the people at the hospitals doing. Urology has nothing to do with Covid 19 so are the urologists just doing nothing. This is unacceptable. When will it become an emergency?
