Final answer:
Certain conditions can lead to the formation of stones when the urine becomes too acidic and long-term antibiotics are used. This applies to uric acid stones, calcium phosphate stones, and struvite stones.
Step-by-step explanation:
When it comes to the formation of stones, if the urine becomes too acidic and long-term antibiotics are used, it can lead to the formation of stones. This is particularly true for certain types of stones, such as uric acid stones, calcium phosphate stones, and struvite stones. For example, conditions like high blood uric acid levels, acid/base metabolism disorders, and urinary tract infections can contribute to the formation of these stones.
