Acoustic wave device for prevention of recurrent suprapubic catheter blockage in neurogenic bladder

BACKGROUND Neurogenic lower urinary tract dysfunction often requires long-term indwelling catheterisation, which is associated with catheter blockages and catheter-associated urinary tract infections, negatively affecting quality of life and healthcare utilization. AIM To evaluate the feasibility and patient-reported outcomes of an acoustic wave device in patients with recurrent suprapubic catheter blockage. METHODS This observational product evaluation included patients with neurogenic bladder and recurrent suprapubic catheter blockages. Participants used the UroShield™ device for 12 weeks. Catheter blockages, catheter satisfaction, pain, and sleep quality were assessed at baseline and during follow-up. RESULTS Ten patients were enrolled; six completed the 12-week evaluation. A reduction in reported catheter blockages and improvements in catheter satisfaction was observed. Four patients withdrew due to bladder spasms, skin irritation, or device practicality issues. CONCLUSION Use of an acoustic wave device was feasible in selected patients and was associated with improved patient-reported outcomes. Findings are preliminary and require confirmation in larger controlled studies.
