A Rare Complication of Amplatz Sheath: Amplatz Sheath Rupture During Percutaneous Nephrolithotomy.

Introduction: Amplatz sheaths are hollow tubes that serve as the portal for the insertion of the nephroscope during percutaneous nephrolithotomy (PCNL). Breakage of this tube during the procedure is rare, but when it does occur it should be recognized and addressed promptly. Case Presentation: A 46-year-old Caucasian male patient was scheduled for PCNL. The Amplatz sheath was inserted in the usual manner over a balloon dilator and nephroscopy was performed. Profuse bleeding was encountered early. Upon meticulous endoscopic navigation, the broken Amplatz tube was recognized and replaced. This allowed us to identify and remove the fragment of the Amplatz tube, followed by stone fragmentation and removal.
Conclusion: Our experience highlights the importance of recognizing this rare complication of a broken Amplatz sheath that should be managed promptly and effectively through endoscopic means without the need to abort the planned PCNL. Copyright 2020, Mary Ann Liebert, Inc., publishers.
