Comparing Efficiency and Stone-Free Rates After Mini-Percutaneous Nephrolithotomy and Flexible Ureteroscopy With Suction Access Sheaths
Northwestern University
Summary
The objective of the study is to compare the stone free rates with ureteroscopy utilizing the ClearPETRA suction ureteral access sheath, and mini-PCNL; both procedures and ClearPETRA sheaths are standard of care and are used regularly for stone treatment. Our primary objective is to assess the complete stone free rate with both procedures.
Description
With the advent of mini-PCNLs, some endourologists have been utilizing the technique to treat renal calculi up to 3cm in size with better stone free rates and similar comorbidity compared to ureteroscopy. These procedures require percutaneous renal access, and it is associated with greater length of stay and fluoroscopy time. The ClearPETRA ureteral access sheath has shown great promise with improving stone free rates, decreasing intra-renal pressure and delivering some of the benefits of mini-PCNL without the added risk associated with obtaining percutaneous renal access. The ClearPETRA fle…
