Assessment of Effectiveness and Safety of Aspiration-Assisted Nephrostomic Access Sheaths in PCNL and Intrarenal Pressures Evaluation: A Systematic Review of the Literature.

Different suction-assisted nephrostomic sheaths have been developed for percutaneous nephrolithotomy (PCNL). (1) To examine PCNL techniques performed with different aspiration-assisted sheaths (Clear Petra sheath, Superperc, SuperminiPCNL, and a miniPCNL patented sheath), with specific regard to effectiveness and safety outcomes in adult and paediatric patients; (2) to extrapolate intrarenal pressure (IRP) data during these procedures. A systematic literature search was performed in accordance with PRISMA guidelines.
