Impact of Ureteral Stent and Sheaths Size on Post-Operative Pain

Impact of Ureteral Stent Size on the Management of Post Ureteroscopy Pain: a Randomized Single Blind Trial

The purpose of this study is to determine if post-operative stent size impacts stent-related pain and discomfort.

Inclusion Criteria:

• Patients undergoing a retrograde intra-renal surgery (RIRS) (only patients undergoing the procedure for stone treatment will be included) who will require post-operative indwelling ureteral stent placement on a string at the conclusion of the procedure.

Exclusion Criteria:

• Patients with intra-operative ureteral injury who will require ureteral stent for extended time (more than 10 days, in that case a stent without a string will be used).
• Patient undergoing ureteroscopy for any indication other than stone extraction.
• Patients who are currently pregnant as determined by clinical presurgical screening.
