Nephroscopic Obliteration of Obstructing Peripelvic Renal Cyst in Conjunction with Stone Removal

Abstract
We report one case in which an obstructing peripelvic cyst was resected nephroscopically through the renal pelvis and two lower caliceal stones were removed by a single access. Extensive fulguration of the cyst was carried out, and a catheter was left in the cyst cavity for 7 days to promote fibrosis and shrinkage. A postoperative nephrostogram and CT follow-up at 21 months revealed unobstructed flow and no recurrence of the cyst.
