How to Use Intrarenal Pressure Monitoring to Identify Risky Steps during RIRS Surgery, and the Function of FANS

Hung-Yi ChenTaiwan Speaker How to Use Intrarenal Pressure Monitoring to Identify Risky Steps during RIRS Surgery, and the Function of FANS.Intrarenal pressure (IRP) elevation during retrograde intrarenal surgery (RIRS) is associated with increased risks of renal injury and infection. Real-time IRP monitoring enables identification of risky procedural steps—such as access sheath insertion, stone fragmentation, and basketing—where pressure spikes commonly occur. Recognizing these moments allows timely adjustments to irrigation and technique. The Flexible and Navigable Suction Ureteric Access Sheath (FANS) plays a key role in pressure management by facilitating continuous suction and efficient outflow, thereby reducing IRP and improving visibility. Incorporating both IRP monitoring and FANS enhances surgical safety and may improve patient outcomes in RIRS.
