Procedure
Extracorporeal Shock Wave Lithotripsy
45 minutes (2Hz)
1 Patients will receive increasing power of SWs from 25% to 80% within 20 shocks. This is the standard SWL treatment protocol in our centre.
2 Patients will receive the first 100 shocks at 40% power and then followed by SWs at 80% power until the end of whole treatment.
3 Patients will receive the first 500 shocks at 40% power and then followed by SWs at 80% power until the end of whole treatment.
4 Patients will receive 500 shocks at 40% power, followed by a 3-minute pause and then further SWs at 80% power until the end of whole treatment.
5 Patients will receive 500 shocks at 80% power, followed by a 3-minute pause and then further SWs at 80% power until the end of whole treatment.
1. Adult patient (aged ≥ 18 years old);
2. Solitary radio-opaque renal stones of total size 5-20mm in maximal diameter as measured from plain radiography;
3. Clinically decided for SWL.
1. Stones associated with any renal or ureteric anatomical abnormality, such as caliceal diverticulum, horseshoe kidney, ureteropelvic junction obstruction etc.
2. Patients with ureteric stent or nephrostomy tube inserted.
