Current clinical evidence in intrarenal temperature, pressure and suction during retrograde intrarenal surgery: a review of literature

Despite the limited clinical evidence, IRTs during RIRS correlate directly with laser power and reversely correlate with irrigation flow rate and UAS use. Intraoperative IRP monitoring prevents hazardous increments. Manual pump irrigation causes extremely high IRPs. There is a possible relation between prolonged IRP increments and infectious complication development. Using suction UAS or flexible and navigable sheaths (FANS) improves operative times and SFRs, while more studies regarding direct in-scope suction (DISS) efficiency and safety are needed.
