“…High RPP can lead to renal damage at varied extents, liquid reflux and extravasation, infection spread, urosepsis, and even infectious shock. From 2009 to 2014, we used the patented designed-suctioning sheath for MPCNL that can lower RPP efficiently and suck out gravel particles automatically, and the surgical safety and efficiency were increased [15,16,17,18]. However, we had to monitor RPP through either a retrogradely placed ureteral catheter or a pressure sensor placed through percutaneous tract; both of them were relatively complicated and could bring trauma to the patient.…”

Introduction: In order to better control renal pelvic pressure (RPP), reduce surgical complications and increase operative efficacy of minimally invasive percutaneous nephrolithotomy (MPCNL), we designed an MPCNL with intelligent monitoring and control of RPP and sought to explore its clinical efficacy and characteristics. Subject and Methods: This study included 60 patients with renal staghorn calculi. A 5F ureteral catheter was connected to an invasive blood pressure monitor for monitoring and control of RPP. A 12F renoscope was inserted through a percutaneous tract for lithotripsy using a laser, with the help of an intelligent system to monitor RPP continuously, which includes an irrigation and suctioning platform and an integrated intraluminal pressure sensory PCNL suctioning sheath. Before the lithotripsy, intraluminal pressure control value and perfusion flow were set on the platform. Results: RPP was maintained at a range of -12 to 2 mm Hg. The mean operative time was 120 min. The mean intraoperative bleeding amount was 100 ml. Fifty-two of the 60 patients the stones were cleared by one surgery. Conclusions: In our suctioning MPCNL with the intelligent control of RPP, the intraoperative RPP could be accurately controlled within the preset safety range. The stone clearance rate was high.

“…Ultrasound-guided percutaneous punctures were made with an 18-gauge coaxial needle into the targeted calix (middle/lower kidney calices) [5,6,8]. The puncture point was in the 12th rib infracostal margin, between the posterior axillary line and scapula line [9].…”

“…An EMS system ultrasound or ballistic trajectory combined with ultrasound was used to break the stones, and the vacuum-suctioning device was used to clear gravel. At the end of the surgery, a 5 F double J stent was inserted in the ureter under the guidance of the ureteral catheter, and a nephrostomy tube of the same caliber (16 F) was left in place [6]. …”

“…We designed a patented system (patent No. ZL200820137434.6) with suctioning ability to facilitate minimally invasive PCNL (MPCNL) [5,6]. This patented system was found to be safe and highly efficient in managing renal stones as revealed in the previous study [6].…”

Objectives: At present, there is no report on the application of Guy's stone (GS) score in minimally invasive percutaneous nephrolithotomy (MPCNL). We therefore investigate the clinical effect of MPCNL by using a patented irrigation and clearance system according to the GS. Methods: A total of 222 consecutive patients were divided into 2 groups that were treated with MPCNL using the patented system or standard PCNL using Electro Medical System (EMS) ultrasound/ballistic trajectory lithotripsy and clearance system, respectively (124 patients in patented system group, 98 patients in EMS system group). The stone complexity and severity of complications were stratified by GS and Modified Clavien grading system in this study, respectively. The success and complication rates between MPCNL and PCNL were compared. Results: The patented system group had a significantly higher success rate (GS3: 95 vs. 43% and GS4: 67 vs. 31%) and a significantly less complications rate (GS3: 12 vs. 27% and GS4: 21 vs. 46%) in GS3 and GS4 compared with the EMS system group. Also, the patented system had significant lower complication rates in Clavien grades II-IV than that of the EMS system. Conclusion: The MPCNL using the patented irrigation and clearance system was more efficient in dealing with renal stones of high complexity (GS3-4).
