EAU 2018: The Surgical Experience Does Not Affect Radiation Exposure During Retrograde Intrarenal Surgery: Preliminary Findings From A Cross Sectional Study

Copenhagen, Denmark (UroToday.com) Current guidelines recommend that fluoroscopy be available during retrograde intrarenal surgery (RIRS) cases for additional safety and complication precaution. However, fluoroscopy is routinely used during RIRS cases and total time used can vary widely depending on operative time, Hounsfield unit, ureteral stone location, stone size and stent insertion. The primary objective of this study was to assess the impact of surgery experience on fluoroscopy time and evaluate what factors may affect fluoroscopy time during RIRS.

The authors analyzed 60 patient who underwent RIRS for this study. Of this patient cohort 28 were performed by a senior surgeon and 32 were performed by a junior resident. Fluoroscopy time, operative time, and radiation dose was measured for all cases.

There was no significant difference in patient age, gender, bmi, preoperative stent, stone number, stone location, stone burden, or Hounsfield units between the two groups. Interestingly, there was also no significant difference in operative time, fluoroscopy time, radiation dose, complication rate and stone free rate between the two groups. When looking at factors that may affect radiation exposure during RIS, the authors found that the biggest factors were longer operative time and double-j stent placement.

The authors concluded that there was no association found between surgical experience and fluoroscopy time and radiation dose during RIRS.

This poster was presented as part of the stone treatment Expert-Guided Poster tour at the EAU Congress.
