By measuring intrarenal pressure in renal time, we were able to determine if the pressure may become elevated and contribute to potential postoperative complications. METHODS: The LithoVue Elite Ureteroscope was used clinically and the first in human cases have occurred in Canada. A pressure bag set at 150 mmHg was used for pressurized irrigation. A ureteral access sheath was used at the discretion of the surgeon. Pressure readings were delivered 4 times a second. Readings of the intrarenal pressure are displayed on the video interface where the endoscopic image is viewed in real time (Figure 1). RESULTS: Two cases are discussed here. One case shows that the intrarenal pressure with a ureteral access sheath ranges between 25-30 mmHg. In the exact same patient on the other kidney, no ureteral access sheath was used and the pressure is seen to be approximately 100 mmHg. Another case shows a patient under spinal anesthesia. When the pressure goes >115 mmHg, the patient describes pain and insertion of a UAS lowers the pressure to 15 mmHg and her pain subsides. CONCLUSIONS: The LithoVue Elite ureteroscope was able to monitor intrarenal pressure in real time. Ureteral access sheath use in these 2 cases showed a decrease in intrarenal pressure and where the patient was awake under spinal anesthetic, a UAS decreased her pain from high intrarenal pressure. The use of a new ureteroscope that can monitor intrarenal pressure in real time will help further investigation of the effects of intrarenal pressure during and after ureteroscopy.
