NCT07772830

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.

Outcome Measures

Primary Outcomes (2)

  • Preoperative State Anxiety Measured by the State-Trait Anxiety Inventory-State (STAI-S)

    Preoperative 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.

    On the day of surgery, before the surgical procedure

Study Arms (2)

RIRS Group

Participants with renal stones who underwent retrograde intrarenal surgery (RIRS) as part of routine clinical care. The surgical approach was determined independently of the study protocol.

Procedure: Retrograde Intrarenal Surgery

PCNL Group

Participants with renal stones who underwent percutaneous nephrolithotomy (PCNL) as part of routine clinical care. The surgical approach was determined independently of the study protocol.

Procedure: Percutaneous Nephrolithotomy

Interventions

Retrograde intrarenal surgery (RIRS) performed for the treatment of renal stones according to routine clinical indications. The procedure was not assigned by the study protocol.

RIRS Group

Percutaneous nephrolithotomy (PCNL) performed for the treatment of renal stones according to routine clinical indications. The procedure was not assigned by the study protocol.

PCNL Group

Sampling MethodNon-Probability Sample
Study Population

Adult patients with renal stones who were scheduled to undergo retrograde intrarenal surgery (RIRS) or percutaneous nephrolithotomy (PCNL) at the Urology Clinic of Samsun University, Samsun Training and Research Hospital, during the study period. Participants were prospectively enrolled from patients receiving routine clinical care, and the choice of surgical procedure was determined independently of the study protocol.

You may qualify if:

  • Patients over 18 years of age
  • Patients scheduled to undergo RIRS or PCNL for renal stones
  • Patients scheduled to undergo general anesthesia
  • Patients who had not previously undergone general anesthesia

You may not qualify if:

  • Patients scheduled to undergo spinal anesthesia
  • Patients undergoing RIRS or PCNL for ureteral stones
  • Patients with a history of general anesthesia
  • Patients with psychiatric or neurological disorders
  • Patients using anxiolytic or antidepressant medications
  • Patients with chronic alcoholism
  • Patients with a history of previous stone surgery
  • Patients with known congenital renal or urinary tract anomalies
