Combined Intravenous and Irrigation Tranexamic Acid During Percutaneous Nephrolithotomy
The Role of Tranexamic Acid Combined Dose Intravenous and in Irrigation Fluid in Optimizing Percutaneous Nephrolithotomy: A Prospective, Randomized, Controlled and Double-blind Study
Percutaneous nephrolithotomy is a minimally invasive surgical procedure used to remove large kidney stones. Although it is an effective treatment, bleeding during and after the procedure remains one of the main concerns and may sometimes require blood transfusion.
Tranexamic acid is a medication that helps reduce bleeding by limiting the breakdown of blood clots. It can be given through a vein and may also be used locally in irrigation fluid during surgery. This study evaluates whether using tranexamic acid by both routes during percutaneous nephrolithotomy can reduce blood loss, improve the clarity of the surgical field during endoscopy, and reduce the need for blood transfusion.
The study included adult patients with kidney stones larger than two centimeters who were suitable for percutaneous nephrolithotomy. Patients were randomly assigned to receive either tranexamic acid through a vein and in the irrigation fluid, or normal saline as a control treatment. Blood loss was assessed using hemoglobin and hematocrit levels before and after surgery, as well as hemoglobin concentration in the irrigation fluid collected at the end of the operation. The surgeon also assessed the clarity of the surgical field using a ten-point visual scale.
The hypothesis of the study is that combined intravenous and local administration of tranexamic acid in irrigation fluid during percutaneous nephrolithotomy reduces blood loss, improves surgical visibility, and lowers the need for blood transfusion compared with normal saline.

Aseet ja interventiot
Osallistujaryhmä / Arm |
Interventio / Hoito |
|---|---|
|
Kokeellinen: Combined Tranexamic Acid Group
Participants in this arm received tranexamic acid 10 milligrams per kilogram intravenously in 250 milliliters normal saline 15 minutes before induction of anesthesia, in addition to the same dose of tranexamic acid added to the first 4 liters of irrigation fluid during percutaneous nephrolithotomy.
|
Tranexamic acid was administered as a combined intravenous and local intervention during percutaneous nephrolithotomy.
The intravenous dose was given before anesthesia induction, and the local dose was added to the initial irrigation fluid used during the procedure.
|
|
Placebo Comparator: Normal Saline Control Group
Participants in this arm received 250 milliliters normal saline intravenously 15 minutes before induction of anesthesia, in addition to normal saline placebo added to the first 4 liters of irrigation fluid during percutaneous nephrolithotomy.
|
Normal saline was used as the placebo comparator.
It was administered intravenously before anesthesia induction and added to the initial irrigation fluid during percutaneous nephrolithotomy.

|
Change in hematocrit concentration after percutaneous nephrolithotomy
Aikaikkuna: Preoperative, immediate postoperative, and 24 hours postoperative
|
Difference in hematocrit concentration measured before surgery and after surgery as an additional indicator of perioperative blood loss.
|
Preoperative, immediate postoperative, and 24 hours postoperative
|
|
Need for blood transfusion
Aikaikkuna: Intraoperatively and up to 24 hours postoperatively
|
Number of participants who required blood transfusion during the intraoperative or postoperative hospital stay period.
|
Intraoperatively and up to 24 hours postoperatively
|
|
Hemoglobin concentration in irrigation fluid
Aikaikkuna: At the end of surgery
|
Hemoglobin concentration measured in the irrigation fluid collected at the end of surgery as an estimate of intraoperative blood loss.
|
At the end of surgery
|
|
Endoscopic surgical field visibility score
Aikaikkuna: At the end of surgery
|
Surgical field visibility was assessed by the operating surgeon using a 10-point visual scale.
The score ranges from 1 to 10, where 1 indicates very poor visibility and 10 indicates perfect visibility.
Higher scores indicate better endoscopic surgical field visibility.
|
At the end of surgery
|
|
Postoperative Hematuria
Aikaikkuna: Up to 24 hours postoperatively
|
Number of participants who developed visible blood-stained urine after percutaneous nephrolithotomy.
|
Up to 24 hours postoperatively
|
|
Need for Additional Hemostatic Intervention
Aikaikkuna: Up to 24 hours postoperatively
|
Number of participants who required an additional intervention to control bleeding after percutaneous nephrolithotomy.
|
Up to 24 hours postoperatively
|
|
Postoperative Infection
Aikaikkuna: Up to 24 hours postoperatively
|
Number of participants who developed postoperative infection after percutaneous nephrolithotomy.
|
Up to 24 hours postoperatively
