BACKGROUND AND PURPOSE: Bosniak III and IV @entity8 have low mortality potential, and little is reported regarding the feasibility and safety of managing such @entity5 by laparoscopy and its comparison with open surgery. We report on the experience with 37 complex @entity8 managed in the era of laparoscopy. @entity1 AND METHODS: A retrospective analysis of a prospective database from all @entity1 with @entity703 who were operated on at our institution was evaluated after Institutional Review Board approval. The database comprises information for demographic, clinical, imaging, preoperative, intraoperative, histologic, and follow-up data. A comparison among all performed approaches was done for demographic, American Society of Anesthesiologists classification, operative time, estimated @entity190 , @entity63 time, hospital stay, oncologic and survival rate. The cysts removed by laparoscopic partial nephrectomy were compared with the solid @entity5 removed by the same approach at the same period. RESULTS: The database included 407 @entity1 with @entity703 who were operated on from 2000 to 2009 at our institution. In 36 @entity1 of the total cohort, there were 37 complex @entity8 . No @entity1 with preoperative Bosniak type I or II underwent surgery. Of the cysts, 60% were Bosniak IV, and 86% were confirmed as malignant; 40% were Bosniak III, and 44% were confirmed as malignant. Laparoscopic partial nephrectomy was performed in 67.5%. The @entity5 size and hospital stay were significantly different in the laparoscopic group. No @entity45 occurred either by laparoscopy or by the open approach, and no @entity5 recurrence was found in a mean follow-up of 43.7 months with overall survival of 100%. CONCLUSION: Laparoscopic surgery for complex cysts is safe, feasible, and effective. Nevertheless, regardless of surgical approach, @entity1 with complex @entity8 have excellent overall survival with short-term follow-up.

Is it safe and effective to treat complex XXXX by the laparoscopic approach?
