title: Laparoscopic decortication of hilar renal cysts using LigaSure.
abstract: OBJECTIVE
  In this study, we evaluated the safety and efficacy of using the LigaSure sealing system (Valleylab, Boulder, Colorado) for laparoscopic decortication of symptomatic hilar renal cysts.
  
  
  METHODS
  Seventeen patients underwent laparoscopic decortication of hilar renal cysts with the LigaSure system. Our study included only symptomatic, Bosniak type 1, simple and symptomatic renal cysts. The operative route, transperitoneal or retroperitoneal, was planned according to the location confirmed by computed tomography. The patients' symptoms were preoperatively and postoperatively evaluated by the Wong-Baker visual pain scale. Operative measures and radiologic outcomes were prospectively evaluated.
  
  
  RESULTS
  The mean age of the patients was 56.4 years, and the mean follow-up period was 12.5 months. Preoperative computed tomography showed only a single cyst in 15 patients (88.2%) and showed two separate cysts in 2 cases (11.8%). The cysts were located in the perihilar region close to the vascular structure in all patients. A transperitoneal approach was used in 9 patients, and a retroperitoneal approach was used in 8 patients. The mean operative time and hospitalization time were 56.4 minutes and 1.2 days, respectively. Minor complications were observed in 3 patients. Symptomatic and radiologic success rates of 94.2% and 100%, respectively, were achieved.
  
  
  CONCLUSIONS
  Laparoscopic decortication of symptomatic hilar renal cysts--first reported in the literature in this study--using the LigaSure sealing system is feasible, effective, and safe, even if the cyst is located in the perihilar area.
