It is well established that uncomplicated distal ureteroscopy can be safely performed without
leaving a ureteral stent. However, many urologists continue to leave ureteral stents
following uncomplicated ureteroscopy, regardless of stone location, due to concerns for
post-operative complications, patient symptoms and to reduce unplanned medical visits. There
is a paucity of data regarding the utility of stent placement for proximal ureteral or renal
stones following ureteroscopy. We have designed a prospective, randomized controlled trial to
evaluate the role of ureteral stent placement following ureteroscopy and pyeloscopy in
proximal and renal stones.

Inclusion Criteria:
- Adult patients age ranges 18-89 with solitary or multiple proximal ureteral or renal
stones 1.5cm or smaller measured in the longest dimension on preoperative imaging (CT
or xray). Proximal ureteral stones are those proximal to the pelvic brim in the
ureter.
Exclusion Criteria:
- Stone size greater than 1.5 cm on preoperative imaging
- Pregnancy
- Stent placement prior to ureteroscopy ("pre-stented patients")
- Patients with solitary kidney
