Comparing supine and prone positions for treating distal ureteric stones with shockwave therapy
Randomized Controlled Study on Extracorporeal Shockwave Lithotripsy for Distal Ureteric Stone: Transgluteal Versus Traditional Prone Approach
This study is testing whether lying on your back or stomach during shockwave therapy can help adults with kidney stones get rid of them more effectively.

What this trial studies
This clinical trial investigates the effectiveness of extracorporeal shockwave lithotripsy (ESWL) for treating distal ureteric stones in two different positions: supine and prone. The study aims to determine if the supine position can improve the stone-free rate compared to the traditional prone position, especially for patients who may have difficulty lying prone due to medical conditions. Participants will be adults over 18 years with stones sized 3mm or larger, and the study will monitor for any complications or side effects associated with each position. The trial is conducted at Queen Mary Hospital in Hong Kong.
Who should consider this trial
Good fit: Ideal candidates are adults over 18 years with distal ureteric stones of size 3mm or larger who are seeking ESWL treatment.
Not a fit: Patients with conditions such as active urinary tract infections, uncontrolled hypertension, or those unable to assume the required positions for ESWL may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could provide a more effective and safer treatment option for patients with distal ureteric stones who cannot tolerate the prone position.
How similar studies have performed: Previous studies have shown promising results with the supine approach, indicating improved outcomes compared to the prone position, suggesting this approach may be effective.
