The Effect of Transcutaneous Electrical Nerve Stimulation in Patients After Retrograde Intrarenal Surgery

Turkey (Türkiye)72 participantsStarted 2026-01-01

Plain-language summary

This study is designed to evaluate the effects of Transcutaneous Electrical Nerve Stimulation (TENS) on pain, nausea, vomiting, and quality of recovery in patients undergoing Retrograde Intrarenal Surgery (RIRS). This prospective, randomized controlled trial, designed as a two-group study, will be conducted at the Department of Urology, Yozgat Bozok University Health Practice and Research Center between September 2025 and September 2026. A total of 72 patients who underwent RIRC and met the inclusion criteria will be included in the study. Participants will be randomly divided into two groups: an intervention group receiving TENS (n=36) and a control group without TENS (n=36). Pain levels, frequency of nausea and vomiting, and quality of recovery in both groups will be compared within the first 24 hours postoperatively. This study is expected to provide evidence-based data on the effectiveness of TENS, a non-pharmacological method, in symptom management after RIRS.
