Summary
Electrohydraulic lithotripsy (EHL) effectively disintegrates renal and ureteral stones using flexible nephro-ureteroscopy. This minimally invasive treatment shows high success rates for stone removal and excretion, offering a valuable option for urolithiasis management.
Area of Science:
- Urology
- Endourology
- Minimally Invasive Surgery
Context:
- Urinary stone management presents challenges in achieving complete stone-free status.
- Flexible nephro-ureteroscopy offers improved visualization and access within the urinary tract.
- Electrohydraulic lithotripsy (EHL) is an established method for stone fragmentation.
Purpose:
- To evaluate the efficacy and safety of electrohydraulic lithotripsy (EHL) combined with transurethral flexible nephro-ureteroscopy for treating renal and ureteral stones.
- To assess stone disintegration and excretion rates, as well as complication incidence.
Summary:
- A study involving 38 patients with 39 renal and ureteral stones utilized EHL with flexible nephro-ureteroscopy.
- A ureteral guide tube aided endoscopic access, with successful stone disintegration in 94.9% and distraction in 89.7%.
- Complete stone excretion occurred in 33 patients within 6 months, with a 7.7% complication rate including ureteral perforation and abscess.
Impact:
- This technique demonstrates high efficacy for urinary stone disintegration and clearance, with a low complication rate.
- Transurethral flexible endoscopy provides excellent visualization, supporting its use as a non-invasive treatment for urolithiasis.
- The approach holds potential as an adjunct to extracorporeal shock wave lithotripsy (ESWL) and for managing other upper urinary tract conditions like tumors.
