Summary
Metallic spirals offer effective urinary retention treatment for elderly patients, enabling immediate voiding post-placement. This minimally invasive approach shows promise, despite potential migration complications.
Area of Science:
- Urology
- Medical Devices
Context:
- Urinary retention and dysuria significantly impact patient quality of life, especially in elderly individuals.
- Indwelling urinary catheters present risks and inconveniences, necessitating alternative management strategies.
Purpose:
- To evaluate the efficacy and safety of metallic spiral insertion for treating urinary retention and dysuria.
- To assess urodynamic parameters and complication rates associated with metallic spiral treatment.
Summary:
- Metallic spirals were successfully placed in 21 of 22 patients (16 with urinary retention, 6 with dysuria) under transrectal ultrasound guidance.
- Immediate post-placement voiding was achieved in all successfully treated patients, with improved urodynamic flow rates and reduced residual volumes.
- Complications included spiral migration (6 patients) and perineal discomfort (3 patients), with most managed successfully; severe complications were absent.
Impact:
- Metallic spiral treatment presents a potentially effective, minimally invasive option for managing urinary retention, particularly in elderly patients or those with comorbidities.
- This device may offer an alternative to indwelling catheters, improving patient comfort and potentially reducing catheter-associated complications.
