Caliceal diverticulum and hydrocalyx - Laparoscopic management

Laparoscopic ablation of calyceal diverticula or hydrocalyces is different than other minimally invasive options for these lesions (shock wave Lithotr ipsy and ureteroscopic and percutaneous nephroscopy) in that it incorporate s complete obliteration of both the cavity and its connection with the coll ecting system. Laparoscopic ablation provides definitive management similar to that achieved with open surgery, but with less patient morbidity. Lapar oscopic treatment of calyceal diverticula or hydrocalyces is an excellent c hoice for anterior cavities without significant overlying renal parenchyma that are large or have an endoscopically inaccessible neck and either a nar row neck or large stone burden.
