Registered outcomes20
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Postoperative pain score | 6 hours after surgery | Pain intensity measured with a 0-10 visual analog scale (VAS); 0 = no pain, 10 = worst imaginable pain. |
| Secondary | Postoperative pain scores | 1, 2 and 24 hours after surgery | Pain intensity measured with a 0-10 visual analog scale (VAS); 0 = no pain, 10 = worst imaginable pain. |
| Secondary | Number of rescue analgesic doses | First 24 hours after surgery | Number of rescue analgesic doses administered in addition to the standardized postoperative analgesic regimen. |
| Secondary | Mean intrarenal pressure | Intraoperative | Mean intrarenal pressure (mmHg) recorded continuously by the pressure-sensing flexible ureteroscope. |
| Secondary | Maximum intrarenal pressure | Intraoperative | Maximum intrarenal pressure (mmHg) recorded during the procedure. |
| Secondary | Time with intrarenal pressure above 30 mmHg | Intraoperative | Total time (seconds) during which intrarenal pressure exceeds 30 mmHg. |
| Secondary | Mean intrarenal fluid temperature | Intraoperative | Mean intrarenal fluid temperature (degrees Celsius) recorded continuously with a temperature probe. |
| Secondary | Maximum intrarenal fluid temperature | Intraoperative | Maximum intrarenal fluid temperature (degrees Celsius) recorded during the procedure. |
| Secondary | Time with intrarenal fluid temperature above 43 degrees Celsius | Intraoperative | Total time (seconds) during which intrarenal fluid temperature exceeds 43 degrees Celsius. |
| Secondary | Irrigation fluid volume | Intraoperative | Total volume of irrigation fluid used (mL), measured by weighing saline bags. |
