Brief summary

This prospective observational cohort study aimed to compare preoperative anxiety levels in adult patients undergoing retrograde intrarenal surgery (RIRS) or percutaneous nephrolithotomy (PCNL) for renal stones. The surgical approach was determined according to routine clinical indications and was not assigned by the study protocol. Preoperative anxiety was assessed using the State-Trait Anxiety Inventory-State (STAI-S) and the Amsterdam Preoperative Anxiety and Information Scale (APAIS). Demographic, clinical, and stone-related characteristics were also recorded to evaluate factors associated with preoperative anxiety.

Detailed description

Adult patients scheduled to undergo RIRS or PCNL for the treatment of renal stones were prospectively enrolled in this single-center observational cohort study. The choice of surgical approach was based on routine clinical assessment, including stone characteristics, anatomical considerations, and the treating urologist's clinical judgment, and was not determined by the research protocol. Before surgery, participants completed the State-Trait Anxiety Inventory-State (STAI-S) and the Amsterdam Preoperative Anxiety and Information Scale (APAIS). Demographic characteristics, comorbidities, American Society of Anesthesiologists (ASA) physical status, and stone-related variables were prospectively recorded. The primary objective was to compare preoperative anxiety levels between patients undergoing RIRS and those undergoing PCNL. The study also evaluated clinical and patient-related factors potentially associated with preoperative anxiety.

Design outcomes

Primary

MeasureTime frameDescription
Preoperative State Anxiety Measured by the State-Trait Anxiety Inventory-State (STAI-S)On the day of surgery, before the surgical procedurePreoperative state anxiety was assessed using the State-Trait Anxiety Inventory-State (STAI-S). The STAI-S consists of 20 items and yields a total score ranging from 20 to 80, with higher scores indicating greater state anxiety.

Secondary

MeasureTime frameDescription
Preoperative Anxiety Measured by the Amsterdam Preoperative Anxiety and Information Scale (APAIS)Preoperatively, on the day of surgery before the surgical procedurePreoperative anxiety was assessed using the Amsterdam Preoperative Anxiety and Information Scale (APAIS). The six-item scale evaluates anxiety related to anesthesia and surgery and the need for information, with higher scores indicating greater preoperative anxiety and/or information need.
