Summary
Pneumatic endoscopic lithotripsy effectively disintegrates urinary stones using a mini-ureteroscope. This minimally invasive technique offers a high success rate for ureteral and bladder stones, with minimal complications when using double-J stents.
Area of Science:
- Urology
- Endourology
- Nephrolithiasis Treatment
Context:
- Urinary stone management often requires minimally invasive procedures.
- Endoscopic lithotripsy is a common modality for stone removal.
- Novel applications of existing technology are continuously explored to improve efficacy and safety.
Purpose:
- To evaluate the efficacy and safety of pneumatic endoscopic lithotripsy using a semirigid ureteroscope.
- To assess the feasibility of applying the lithotripsy probe through a tangential working channel of a mini-ureteroscope.
- To determine stone-free rates and identify potential complications associated with this technique.
Summary:
- Endoscopic lithotripsy was performed on 23 urinary stones (21 ureteral, 2 bladder) using a pneumatic shockwave unit and a 6.9-Fr semirigid ureteroscope.
- Complete stone disintegration was achieved in all cases (stone size 5-24 mm).
- Immediate stone-free rates were 47.6% for ureteral stones, with residual fragments in some cases. No ureteral perforations occurred, and double-J stents prevented serious complications.
Impact:
- Pneumatic endoscopic lithotripsy is highly effective for urinary stone disintegration, regardless of stone composition.
- The technique is easily applicable through mini-ureteroscopes, offering a minimally invasive treatment option.
- Routine use of double-J stents is crucial for preventing postoperative complications.
