Objective:
To evaluate the feasibility and clinical efficacy of employing a homemade lasso to control the renal blood flow in retroperitoneal laparoscopic nephron-sparing surgery for the treatment of renal tumors.
Methods:
Eight patients with benign renal tumors and 14 with malignant renal tumors underwent enucleation and wedge resection of renal tumors through retroperitoneal laparoscopy. Of these 22 patients, 15 were males and 7 females with a mean age of 45 years old. The mean tumor diameter was 3.2 cm.
Results:
All the procedures were technically successful without conversion to open surgery in all 22 patients. The mean operative time was 150 min and mean blood loss 80 ml. The mean postoperative hospital stay was 8 days. No intraoperative or postoperative complication occurred. All 14 cases of malignant renal tumors had a negative surgical margin. With a follow-up of 5-29 months, no recurrence occurred.
Conclusion:
Retroperitoneal laparoscopic partial nephrectomy is feasible and safe for selective patients with renal tumors. Using a homemade lasso to control the renal blood flow in retroperitoneal laparoscopic partial nephrectomy is simple and less interferential.
