About this study
Official title: Effect of Ureteral Access Sheath Use on Postoperative Pain Level in Patients Undergoing Retrograde Intrarenal Surgery (RIRS)
This study will include patients aged between 18 and 70 who will undergo retrograde intrarenal surgery (RIRS) due to renal stone(s). A total of 80 patients (male or female) will be recruited, and will be randomized into 2 groups consisting of 40 patients in each group. The first group of patients will undergo RIRS with a ureteral access sheath (UAS) positioned prior to surgery; and the second group will undergo RIRS without UAS. As use of UAS decreases the pressure in the renal pelvis during RIRS, it is aimed to evaluate whether using UAS or not affects the level of pain felt by patients in the postoperative period.
Read the detailed description
The level of pain of the patients in both groups will be evaluated by using visual analog score (VAS) and verbal rating score (VRS) in the postoperative 0 min (the moment patients gets consciousness after he/she wakes up from general anesthesia), 10th min, 30th min, 60th min and 120th min.

| Study group | Role | What they receive |
|---|---|---|
| UAS (+) | Active comparator | RIRS with ureteral access sheath: A ureteral access sheath (UAS) will be positioned into the ureter of the patient prior to the insertion of the flexible ureterorenoscope (RIRS). Receives: Device: RIRS with ureteral access sheath |

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
This study will include patients aged between 18 and 70 who will undergo retrograde intrarenal surgery (RIRS) due to renal stone(s). A total of 80 patients (male or female) will be recruited, and will be randomized into 2 groups consisting of 40 patients in each group. The first group of patients will undergo RIRS with a ureteral access sheath (UAS) positioned prior to surgery; and the second group will undergo RIRS without UAS. As use of UAS decreases the pressure in the renal pelvis during RIRS, it is aimed to evaluate whether using UAS or not affects the level of pain felt by patients in the postoperative period.
Detailed description
The level of pain of the patients in both groups will be evaluated by using visual analog score (VAS) and verbal rating score (VRS) in the postoperative 0 min (the moment patients gets consciousness after he/she wakes up from general anesthesia), 10th min, 30th min, 60th min and 120th min.

Questions about this trial
What is this clinical trial studying?
A study testing RIRS with ureteral access sheath and RIRS without ureteral access sheath in people with Urolithiasis, run by Selcuk University at 1 site in Turkey (Türkiye).
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 18 Nov 2019. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Turkey (Türkiye). Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Postoperative pain level (time frame: Within the first 2 hours after the surgery (RIRS)). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02501525, which also lists 8 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Nov 2019.
