Summary

The primary aim of this study is to investigate the temperature profiles in the renal pelvis during ureteroscopic Thulium Fiber Laser activation using different settings. To this end, comparison of peak temperatures during laser activation for different settings is the main aim. Secondary aim is trying to define the duration of safe laser activation until the threshold for heat induced cell injury (43oC) is reach.

Patients ≥ 18 years with a ureteral stone (with or without a concomitant renal stone) and an indwelling nephrostomy tube scheduled for ureteroscopic lithotripsy at the day surgery unit at Haukeland University Hospital, are eligible to enrolment in the study.

Temperature measurements during ureteroscopic laser stone disintegration will be performed. Follow-up is standardised with clinical consultation and low dose CT 3 months post endoscopically.
