A Comparison between Laparoendoscopic Single-Site and Conventional Laparoscopic Renal Stone Removal Surgery: A Study of Application in Two Cases
Abstract: Aim: To present our initial experience of applying laparoendoscopic single-site surgery (LESS) nephrolithotomy in the treatment of renal calculi. Methods: In August 2010 and April 2012, the LESS nephrolithotomy technique was applied to treat two patients with a renal calculus. One patient had a calculus measuring 5 × 3 cm, and the second patient's measured 3 × 3 cm. Both patients underwent general anesthesia. The operations were performed through a retroperitoneal approach with a single-port instrument inserted through the retroperitoneal incision. The standard laparoscopic retroperitoneal technique was performed, and the calculi were removed by incising the area of the thin renal cortex and the renal pelvis, respectively. The operating time, estimated blood loss, intraoperative complications, other complications, drainage time, and post-operative hospital stay were recorded. Results: Both procedures were completed successfully. No additional trocars were added. No conversion to standard laparoscopic or open surgery was needed. The operating times were 130 min and 120 min, and the estimated blood losses were 40 mL and 30 mL. There were no intraoperative complications. The wound drainage times were 3 d and 2 d, respectively and the post-operative hospital stays were 8 d and 7 d, respectively. There was no secondary bleeding or wound infection. Follow-up times were 2 years and 3 months, respectively. No incidence of hydronephrosis was recorded. Conclusions: LESS nephrolithotomy is safe and feasible for treating kidney calculi. It can be applied in patients with large renal calculi and regionally thin renal parenchyma.
