A novel urethral sheath significantly reduces bladder stone removal time during transurethral lithotripsy. This new sheath offers a simpler and more effective surgical option for managing bladder calculi.
Area of Science:
- Urology
- Surgical Technology
- Medical Devices
Background:
- Transurethral lithotripsy is a common procedure for bladder stones.
- Existing methods can be time-consuming and complex.
- Improvements in surgical tools are needed to enhance efficiency.
Purpose of the Study:
- To evaluate the efficacy of a new urethral sheath in transurethral lithotripsy for bladder calculi.
- To compare the performance of the new sheath against conventional methods.
Main Methods:
- 120 bladder stone (BS) models were divided into three groups (n=40 each).
- Control Group 1 used a ureteroscope; Control Group 2 used a ureteroscope via a resectoscope sheath.
- The Test Group utilized the novel JQL urethral sheath for stone removal.
Main Results:
- Mean BS removal times were significantly shorter in the test group (11.5±5.5 min) compared to Control Group 1 (86±15.5 min) and Control Group 2 (45.5±12.2 min) (P=0.001).
- This efficiency improvement was observed across various stone sizes (1.5 cm, 2.0 cm, 3.0 cm).
- The new sheath demonstrated a marked reduction in operative time for all stone sizes.
Conclusions:
- The new JQL sheath is effective for transurethral management of bladder stones.
- It significantly improves surgical efficiency, leading to a simpler and more effective operation.
- This innovation holds promise for optimizing bladder stone treatment.
