About this study

Extracorporeal shockwave lithotripsy (ESWL) for urinary stone is common and widespread nowadays. Approximately 80% of urinary stones are treated by ESWL. Traditionally distal ureteric stones are treated with ESWL in the prone position. However, as some patients cannot tolerate lying in the prone due to medical illness such as chronic obstructive pulmonary disease (COPD), some authors have reported using the supine approach of ESWL for treatment of distal ureter stones. No serious complications had developed in the patients who underwent supine approach. Only minor complications such as self-limiting blood in the urine, painful passage of urine, or local pain that had responded to oral painkillers. There were no serious complications encountered in children as well. In the most recent retrospective review by Tolley et al, they had revealed that patients who had underwent supine ESWL for distal ureteric stones had an improved stone-free rate compared with the traditional prone approach. Patient with radio-opaque distal ureteric stones (stones below the sacroiliac joint) on KUB X-ray, who have opted for ESWL treatment, are randomized into two groups: one undergoing ESWL in the supine position and the other undergoing ESWL in the prone position. Patients will be observed for two hours after ESWL before being discharged. Oral painkillers as necessary will be provided to the patient. The patients will have a KUB Xray at 2 weeks post-ESWL, and then monthly afterwards if required. I…
