Retroperitoneal Laparoscopic Renal Cystectomy:Report of 80 Cases / 中国微创外科杂志

ABSTRACT

Objective To evaluate the efficacy of retroperitoneal laparoscopic renal cystectomy.Methods A total of 80 patients with renal cyst were enrolled in this study.Under general anesthesia,the retroperitoneal cavity was established by using water-filled balloon.The renal cyst were exposed by identifying the psoas major muscle.The cysts were unroofed at 5 mm from the edge of the renal parenchyma with electrical claw.Results The operation was completed in all the cases without severe complications.The operation time was 20-100 min(mean 39 min),blood loss was 5-65 ml(mean 20 ml),and hospital stay was 4-11 d(mean 5.6 d).Postoperative pathological examination showed that all the cysts were simple renal cysts.The 80 patients were followed up for 2-24 months(mean 11 months),3 of them were diagnosed as having residual cyst at 2 months after the operation.Conclusion Retroperitoneal laparoscopic renal cystectomy is safe and effective and is superior in mild surgical trauma,quick recovery,and short hospitalization.
