The goal of this observational study is to understand how satisfied patients are after getting medical advice about urinary stone disease from either a real doctor or an artificial intelligence (AI) chatbot. We want to learn whether people feel more satisfied with the information and support they get from human doctors or from AI tools like ChatGPT, Gemini, Perplexity, or Copilot.

The main questions it aims to answer are:

• Are patients more satisfied after consulting a real doctor or an AI chatbot?
• Does the time spent in the consultation affect satisfaction?

Researchers will compare doctor consultations with consultations from different AI chatbots to see if there are differences in patient satisfaction.

Participants will:

• Ask all their medical questions about urinary stones to one of the sources (a doctor or a specific AI chatbot)
• Fill out a short questionnaire (CSQ-8) to rate how satisfied they felt with the answers they received

Inclusion Criteria:

• Newly diagnosed with urinary stone disease,
• Aged 18 years or older,
• Provided written informed consent to participate in the study.

Exclusion Criteria:

• History of previous urinary stone disease, stone-related procedures,
• Presence of other acute medical conditions unrelated to urinary stone disease,
• Cognitive or communication impairments,
• Pregnancy.
