Techniques in Endourology - Percutaneous Resection of Renal Cysts

Abstract

Symptomatic renal cysts can be managed endoscopically via retrograde ureterorenoscopy, antegrade percutaneous nephroscopy, or laparoscopy. Although all three methods are minimally invasive and effective, the retrograde approach is limited by the size and location of the cyst. Laparoscopy is also effective but is associated with multiple port sites, extensive dissection, and technical difficulty. We utilize percutaneous transparenchymal endocystolysis as a first-line therapy. The technique is described in detail.
