Background:

Hydronephrosis is a dangerous complication of ureteral stents.
Current monitoring methods for hydronephrosis are limited.

Purpose of the Study:

To develop an intelligent double-J ureteral stent for continuous wireless kidney pressure monitoring.
To enable early detection of ureteral obstruction and hydronephrosis.

Main Methods:

Prototyped an intelligent ureteral stent with integrated micro pressure sensor and antenna circuitry.
The stent functions as a radiofrequency resonator with pressure-sensitive frequency.
Tested mechanical durability and wireless sensing in artificial urine and an in vitro hydronephrosis model.

Main Results:

The stent prototype passed mechanical bending tests (15 cm radius of curvature).
Achieved wireless sensing sensitivity of 3.1 kHz/mmHg in artificial urine.
Demonstrated a 25x enhancement in sensitivity compared to previous designs.

Conclusions:

The intelligent ureteral stent shows promise for real-time, wireless monitoring of kidney pressure.
This technology could significantly improve the detection and management of hydronephrosis.
Further clinical research is warranted to advance intelligent ureteral stent technology.
