Concomitant Laparoendoscopic Single-Site Surgery for Ureterolithotomy and Contralateral Renal Cyst Marsupialization

ABSTRACT

A 63-year-old woman presented with acute right-flank pain and left-flank pain. Computed tomography identified a right ureter stone and a left renal cyst. The patient underwent concomitant laparoendoscopic single-site surgery (LESS) for ureterolithotomy and renal cyst marsupialization with the use of an Alexis(R) wound retractor, which was inserted through the umbilical incision. Flexible laparoscopic instruments and conventional rigid instruments were used during LESS following a procedure similar to that used with conventional laparoscopic surgery without additional transcutaneous ports. LESS may be more efficient at treating bilateral diseases than is conventional laparoscopic surgery.
