What this trial studies

This clinical trial investigates the effectiveness of adding Dexmedetomidine or Tramadol to Paracetamol in reducing catheter-related bladder discomfort (CRBD) in patients undergoing percutaneous nephrolithotripsy (PCNL). The study aims to evaluate how these medications can alleviate postoperative pain and discomfort associated with urinary catheters. Participants will receive either Dexmedetomidine or Tramadol alongside Paracetamol during their surgical procedure. The trial focuses on patients aged 20 to 50 years with specific health criteria to ensure safety and efficacy.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 20 to 50 years who are classified as ASA I or II and are scheduled for percutaneous nephrolithotomy.

Not a fit: Patients with a history of psychotic illnesses, current opioid users, or those with bladder obstruction or overactive bladder may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce postoperative bladder discomfort for patients undergoing urinary procedures.

How similar studies have performed: Other studies have shown promising results with similar approaches to managing postoperative pain and discomfort, suggesting potential for success in this trial.
