Comparison of Suction and Conventional Ureteral Access Sheaths in Kidney Stone Surgery
The goal of this observational study is to compare conventional and suction (aspiration) ureteral access sheaths used during retrograde intrarenal surgery (RIRS) in adults with kidney stones. The main questions it aims to answer are: Does the use of a suction ureteral access sheath increase the stone-free rate compared with …
Perioperative Biomarkers and Postoperative Delirium in Older Adults Undergoing Abdominal Cancer Surgery
This prospective observational cohort study aims to investigate the relationship between perioperative endogenous melatonin levels and postoperative delirium in patients aged 65 years or older undergoing elective abdominal cancer surgery. The study will also evaluate serotonin, kynurenine, kynurenic acid, and vitamin B12 as potential biomarkers associated with postoperative delirium. Participants …
Anterior Segment Anatomy Assessed by Swept-Source OCT in Ocular Surgery Patients
This observational study aims to evaluate ocular anatomical parameters in patients undergoing anterior segment surgery using swept-source optical coherence tomography (SS-OCT). Anterior segment surgery, including procedures involving the cornea, lens, and other anterior eye structures, may be associated with changes in ocular anatomy. SS-OCT is a non-invasive imaging technique that …
One-level and Bi-level ESPB Application in Patients Undergoing Breast Surgery
Acute pain after breast surgery can significantly reduce the quality of life for patients. If acute pain is not adequately treated, it can develop into chronic pain. Thoracic epidural analgesia, thoracic paravertebral block, erector spinae plane block, and serratus anterior plane block are frequently applied blocks. However, ESPB, being a …
ESPB Versus SPSIPB for Quality of Recovery After Video-Assisted Thoracoscopic Surgery
Video-assisted thoracoscopic surgery (VATS) is associated with moderate to severe postoperative pain despite its minimally invasive nature. Ultrasound-guided erector spinae plane block (ESPB) and serratus posterior superior intercostal plane block (SPSIPB) are promising regional analgesic techniques for thoracic surgery; however, evidence directly comparing their effects on postoperative quality of recovery …
Effect of Oral Laxative Use Before Colorectal Surgery on Intraoperative Surgical Difficulty
This prospective randomized pilot study will evaluate whether the use of an oral laxative before elective laparoscopic colorectal surgery affects small-bowel diameter and intraoperative surgical difficulty. Adult patients scheduled for elective laparoscopic colorectal resection will be randomly assigned to receive either oral laxative plus rectal enema preparation or rectal enema …
Early Discharge With Hospital-at-Home After Bariatric Surgery and Economic Evaluation.
Bariatric surgery is the most effective treatment for severe obesity and its associated diseases. Advances in surgical techniques, enhanced recovery protocols, and multimodal perioperative care have made earlier hospital discharge possible while maintaining patient safety. This observational cohort study aims to evaluate the economic impact of an early discharge pathway …
Role of Pre-stenting Before Retrograde Intrarenal Surgery With Miniaturized Flexible Ureteroscopes
This prospective randomized controlled trial will compare retrograde intrarenal surgery performed after routine preoperative ureteral stenting with direct retrograde intrarenal surgery without planned preoperative stenting in adults with unilateral renal calculi measuring 10-20 mm. The study will evaluate stone-free rate, ureteral access, need for rescue stenting, operative outcomes, complications, staged …
Pain Control With Ketorolac and Nerve Block After Wrist and Hand Surgery
The purpose of this study is to learn about the effectiveness of different pain control options after hand and wrist surgery, specifically Ketorolac, Tylenol, and a regional nerve block. Ketorolac (Toradol) is a nonsteroidal anti-inflammatory drug (NSAID) that is similar to ibuprofen (Motrin or Advil). Tylenol (acetaminophen) is a commonly …
Effects of Biased Opioid Agonists on Gastrointestinal Recovery After Gynecologic Laparoscopic Surgery
This randomized controlled clinical trial aims to evaluate the effects of different opioid analgesics on gastrointestinal recovery after gynecologic laparoscopic surgery. Opioid medications are commonly used to manage pain after surgery, but they may cause nausea, vomiting, constipation, and delayed recovery of bowel function. Biased μ-opioid receptor agonists, such as …
