Laparoscopic ablation of giant renal cyst

We report a case of a symptomatic giant (18x10x8-cm) renal cyst in a 40-year-old woman that was marsupialized laparoscopically and excised. The surgical technique, based on progressive decompression of the cyst, is fully described. Excellent results were achieved. The recent application of laparoscopic ablation of different types of renal cysts is reviewed. This minimally invasive technique, when properly mastered, is highly effective and offers results similar to those of open surgery. It is associated with definitive postoperative advantages and is the treatment of choice for very large renal cysts, especially those located anteriorly, when sclerotherapy is ineffective or is contraindicated.
