Summary
This study explored regional kidney ischemia during laparoscopic partial nephrectomy using a novel kidney grasper. The technique shows promise for targeted ischemia in kidney cancer surgery.
Area of Science:
- Urology
- Surgical Innovation
- Oncology
Background:
- Laparoscopic partial nephrectomy is standard for kidney tumors.
- Achieving targeted ischemia remains a challenge.
- Current methods may lead to prolonged or non-regional ischemia.
Purpose of the Study:
- To assess the feasibility of regional kidney ischemia during laparoscopic partial nephrectomy.
- To evaluate a novel kidney grasper for precise ischemia application.
- To determine the safety and efficacy of this technique in renal cell carcinoma patients.
Main Methods:
- A transperitoneal approach was used in 5 renal cell carcinoma patients.
- A kidney grasper was employed to induce regional warm ischemia.
- Tumor resection and suturing were performed under controlled partial ischemia.
Main Results:
- The procedure was successfully completed in 4 out of 5 patients.
- Mean partial warm ischemia time was 23.6 minutes.
- Mean blood loss was 110 mL, with variable outcomes.
Conclusions:
- Regional ischemia using a kidney grasper is a feasible option for partial nephrectomy.
- This technique may offer advantages in managing ischemia during kidney tumor resection.
- Further studies are warranted to confirm its broad applicability and refine the technique.
