Toilet drain pipe clogged with urine scale

The wastewater pipe of our toilet was completely clogged with urine scale and recently had to be extensively cleaned. However, our house is only 10 years old, and after such a short time, a wastewater pipe cannot completely clog up, can it? The craftsman said it is due to the pipes and their rough surfaces; such pipes would not be used nowadays. Now the question is whether I should replace the pipes or if there is a way to prevent urine scale. Does anyone have a tip?

A strong buildup of limescale can also be increased by exclusively using the water-saving flush button of the toilet; then too little water flows to properly flush the pipe. Occasionally using the full flush performance would be better. Try it that way first before spending a lot of money on new pipes.
