“…Additionally, a percutaneous needle nephroscope (Needle-Perc) with an outer sheath size of only 4.2 Fr has been developed and can serve as both a visual and puncture system. Another obvious innovation is the incorporation of negative-pressure suction in percutaneous renal sheaths, such as the percutaneous renal suction sheath invented by Song Leming, the ClearPetra sheath with negative-pressure aspiration capability, the Seplou percutaneous nephrostomy suction sheath, and the SMP sheath [ 10 , 11 ]. The utilization of lithotripsy tools such as the Moses laser and thulium laser represents another facet of new technology.…”

Background To test the reliability and safety of a newly invented technique for minimally invasive percutaneous nephrolithotomy, intelligent pressure-controlled minimally invasive percutaneous nephrolithotomy (IPC-MPCNL). Methods Eighteen kidneys of nine female pigs were randomly divided into three groups. Those in Groups A and B underwent IPC-MPCNL through the new system composed of a pressure-measuring MPCNL suctioning sheath and an irrigation and suctioning platform with pressure feedback control. The infusion flow rate was 500 ml/min in Group A and 750 ml/min in Group B. Those in Group C underwent MPCNL at an infusion flow rate of 500 ml/min. The renal pelvic pressure (RPP) monitored by a ureteral catheter and that monitored by the pressure-measuring sheath in Groups A and B were compared. The RPP in Group C was monitored by a ureteral catheter. Results The RPP measured by the pressure-measuring sheath and that measured by the ureteral catheter in Group A was − 5.59 ± 1.95 mmHg and 4.46 ± 2.08 mmHg, respectively. The RPP measured by the pressure-measuring sheath and that measured by the ureteral catheter in Group B was − 4.00 ± 2.01 mmHg and 5.92 ± 2.05 mmHg, respectively. Hence, the RPPs measured by the pressure-measuring sheath in Groups A and B were consistent with those measured by the ureteral catheter. The RPP in Group C was 27.75 ± 5.98 mmHg (large fluctuations). Conclusions IPC-MPCNL can be used to accurately monitor the RPP and maintain it within a preset safe range via suction. The new technique and the new system are safe and reliable.
