SYSTEM FOR REDUCING URETERAL INSERTION PRESSURE BY ARTIFICIALLY TRIGERRING HYDRONEPHROSIS BASED ON MEASUREMENT OF PRESSURE ASSOCIATED WITH THE INSERTION OF THE URETERAL ACCESS SHEATH FOR RETROGRADE INTRARENAL SURGERY

摘要

The present invention is based on the measurement of the pressure associated with the insertion of a ureteral access sheath (UAS) for retrograde intrarenal surgery (RIRS) to determine the location of the UAS in the ureter, the UAS When the ureter reaches an appropriate position in the ureter, artificially induces hydronephrosis by injecting fluid into the ureter, thereby reducing the ureteral insertion pressure of the UAS and minimizing the occurrence of intraureteral wounds caused by the insertion of the UAS into the ureter. will be. According to various embodiments of the present disclosure, in a system, comprising: a Y-shaped medical connector, and a device coupled to the medical connector, the medical connector comprising: a first cylinder including a first opening and a second opening; and a second cylinder connected at an angle to the first cylinder and including a third opening so that the fluid is introduced into the third opening so that the fluid can be discharged through the first opening, wherein the first opening is a ureter entry house ( ureteral access sheath (UAS), wherein the first cylinder is configured to pass a guide wire through the first opening and the second opening, the guide wire passing through the UAS, the device comprising: a memory, a processor, and a UAS a force measurement gauge configured to measure a UAS insertion force (UASIF) upon insertion of the UAS into the bladder and ureter, wherein the processor determines the position of the UAS within the bladder and ureter based on the measured UASIF A system is provided, configured to determine.
