简要总结

This prospective randomized controlled study will compare two techniques used after percutaneous nephrolithotomy, a procedure for removing kidney stones. Participants with renal stones measuring 2-3 cm will be randomly assigned to either tubeless percutaneous nephrolithotomy with nebulized Glubran 2 used to seal the access tract or conventional percutaneous nephrolithotomy with placement of a nephrostomy tube. The study will evaluate whether the Glubran 2-assisted tubeless technique is safe and effective and whether it can reduce postoperative pain, bleeding, hospital stay, urine leakage, and other complications while maintaining a satisfactory stone-free rate.

研究组 & 干预措施

Nebulized Glubran 2-Assisted Tubeless PCNL

Experimental

Participants will undergo percutaneous nephrolithotomy followed by tubeless closure of the percutaneous access tract. After stone removal and confirmation of no significant collecting-system injury, 1 mL of Glubran 2 will be delivered into the tract using a special nebulizing applicator under endoscopic and fluoroscopic guidance. The tract will be temporarily occluded using the balloon of a 16 Fr Foley catheter. No nephrostomy tube will be placed. A 6 Fr double-J ureteral stent may be inserted when clinically indicated.

干预措施: Nebulized Glubran 2-Assisted Tubeless PCNL (Procedure)

Conventional PCNL With Nephrostomy Tube

Active Comparator

Participants will undergo conventional percutaneous nephrolithotomy. After stone removal, a 24 Fr Nelaton tube will be placed as a nephrostomy tube for postoperative drainage. The nephrostomy tube is planned to be removed after approximately 24 hours, according to the participant's clinical condition. A 6 Fr double-J ureteral stent may be inserted when clinically indicated.

结局指标

主要结局

Postoperative Pain Intensity

时间窗: Within the first 24 hours after surgery

Postoperative pain will be assessed using the Visual Analog Scale, ranging from 0 to 10, where 0 indicates no pain and 10 indicates the worst imaginable pain. Scores will be compared between the nebulized Glubran 2-assisted tubeless PCNL group and the conventional PCNL group.

次要结局

  • Stone-Free Rate(At 24 hours after surgery)
  • Postoperative Hemoglobin Change(From baseline before surgery to 24 hours after surgery)
  • Blood Transfusion Requirement(From the end of surgery through 24 hours after surgery)
  • Urinary Leakage(From the end of surgery through 48 hours after surgery)
  • Length of Hospital Stay(From the end of surgery through 30 days after surgery)
  • Intraoperative Blood Loss(Intraoperatively)
  • Fluoroscopy Exposure Time(Intraoperatively)
