Effectiveness of harmonic scalpel in laparoscopic treatment of simple renal cyst.

We retrospectively evaluated the results of Harmonic Scalpel (Ethicon, Cincinnati, Ohio) used for laparoscopic decortication of simple renal cysts (SRC). Between May 2011 and December 2014, 28 patients with symptomatic SRC (Bosniak type 1) underwent laparoscopic decortication with Harmonic Scalpel, were reviewed. All cysts were evaluated with ultrasonography and abdominal computed tomography. Symptomatic and surgical success was defined as no recurrence on computed tomography imaging and complete pain relief, respectively. The mean age of patients was 51.7±9.6 years and there were 16 female and 12 male. While a transperitoneal approach was preferred in 18 cases, a retroperitoneal approach was chosen in 10 patients. The mean cyst size and duration of operation was 8,8±2,8 (6-12) cm and 72,8±28,4 (50-110) minutes, respectively. A total of three minor complications were observed postoperatively. Mean hospital stay was 1,3±0,9 (1-3) days. After the mean 12,6±3,2 (3-24) months follow-up the radiological and symptomatic successes were 100% and 89,2%, respectively. Our results showed that laparoscopic decortication of SRC using Harmonic Scalpel is consistent with the literature and provides a reasonable complication but increases cost.
