The purpose of this study is to compare two variations of the mini-PCNL procedure using either a vacuum-assisted sheath or standard sheath which are both used for the surgical treatment of kidney stones. Both procedure types are commonly used in the treatment of kidneys stones and they have been shown to be safe and effective in the treatment of stones similar in size and location to your own.
In this study we aim to compare two variations of the miniaturized percutaneous nephrolithotomy (Mini-PCNL) procedure which are both used for the surgical treatment of kidney stones. This procedure involves accessing the kidney via a small temporary tract that is placed through the patient's back during surgery. Both procedure types are commonly used in the treatment of kidneys stones and they have been shown to be safe and effective in the treatment of stones similar in size and location to your own.
Two procedure types will be investigated:
Approximately 90 people will take part in this study at Cleveland Clinic. The duration of the study will include the day of the surgery and following hospital stay until postoperative follow-up appointment with the surgeon approximately 4-6 weeks after the procedure.

| Measure | Description | Time Frame |
|---|---|---|
| Aim 1: Stone free rate | The primary outcome of SFR will be measured using conventional follow up of post-operative NCCT at 6 weeks. NCCT provides the most definitive assessment for post-operative stone burden and allows assessment of radiolucent stones when compared to ultrasound or abdominal x-ray | 6 weeks |
| Aim 2: Intraoperative variables | Patients with positive cultures will be treated with appropriate pre-operative antibiotics between 3 to 7 days depending on symptoms. Antibiotics on day of surgery will be selected according to their last pre-operative urine culture which is our standard of care for patients undergoing PCNL | 3-7 days |
| Aim 3: Post-operative Outcomes and Complications | Post-operative pain scores will be evaluated using a visual analogue scale (VAS) in the post-anesthesia care unit (PACU) and on postoperative day 1. The questionnaire may be filled out on a paper survey or an electronic REDCap survey sent via email. An electronic VAS has shown to be reliable and interchangeable with a paper VAS | 1 day |
