Objective: To investigate the operative technique and the clinical value of retroperitoneal laparoscopic enucleation of the renal hamartoma.
Methods: Twenty-five patients of renal hamartoma received retroperitoneal laparoscopic enucleation. The patients were placed in lateral decubitus position. All laparoscopic surgical procedures were performed retroperitoneally using 3 port-sites. The tumor was exposed and resected along the edge, and the tumor clipped out with a lithotomy forceps. The renal hamartoma was confirmed through a pathological diagnosis during the operation. The resection surface was sutured with fibrin and absorbable hemostatic gauze.
Results: The operations were finished successfully in all patients. The diameter of tumors ranged from 1.8 cm x 2.0 cm to 4.5 cm x 4.9 cm. The operative time was 50 - 90 (mean=70) min. The blood loss was 30 - 80 (mean=55) mL. The hospital stay was 7 - 9 (mean=8) days.
Conclusion: Retroperitoneal laparoscopic enucleation of the renal hamartoma is safe and effective, whose advantages include minimal invasive, less blood loss, short hospital stay, and rapid convalescence.
