title: Laparoendoscopic single-site renal cyst marsupialization using a homemade single-port device has a role as a feasible treatment option.
abstract: OBJECTIVE
  In patients with a renal cyst and concurrent symptoms, we examined the effectiveness and safety of laparoendoscopic single-site surgery (LESS) for renal cyst marsupialization using a homemade single-port device (HSPD) by a single surgeon (S.W.L.).
  
  
  METHODS
  The present study was conducted on a total of 31 patients with a renal cyst. A LESS renal cyst marsupialization was performed using a HSPD based on the Alexis® wound retractor and a powder-free surgical glove. In our study, the mean age was 55.29 ± 10.86 (range 31-73) years and the mean size of the renal cyst was 6.83 ± 1.09 cm.
  
  
  RESULTS
  All the surgical procedures were successfully performed. The mean operative time was 101.35 ± 16.04 min. Of the patients who underwent the procedure, none presented with major complications. In 7 patients who had pain preoperatively, there was a significant difference in the visual analogue pain scale score at 6.86 ± 0.69 preoperatively and 1.71 ± 0.49 at postoperative week 4 (p < 0.001). The number of patients who were satisfied with the postoperative outcome was 29 (93.5%).
  
  
  CONCLUSIONS
  In patients with a simple renal cyst, LESS renal cyst marsupialization using a HSPD might be considered as a feasible, safe surgical treatment option.
