Summary
Extracorporeal shock wave lithotripsy (ESWL) effectively treated kidney stones in patients with horseshoe kidneys. Follow-up showed stone absence or manageable fragments in most cases, indicating ESWL
Area of Science:
- Urology
- Nephrology
- Medical Technology
Background:
- Horseshoe kidneys present unique anatomical challenges for treating kidney stones (lithiasis).
- Extracorporeal shock wave lithotripsy (ESWL) is a common modality for kidney stone management.
Purpose of the Study:
- To evaluate the efficacy and outcomes of ESWL in patients with horseshoe kidneys.
- To assess the success rate of ESWL in clearing or reducing stone burden in this specific patient population.
Main Methods:
- Retrospective analysis of 28 patients (34 renal units) with horseshoe kidneys undergoing ESWL.
- Patients were primarily positioned in supine decubitus with calculus in F2.
- A total of 47 ESWL sessions were performed, with 3 additional ureteroscopies.
Main Results:
- Complete stone absence was achieved in 13 renal units.
- Small residual debris (<3 mm) was observed in six renal units.
- Non-removable fragments were noted in 13 cases, and two cases experienced stone recurrence.
Conclusions:
- ESWL demonstrates feasibility and provides acceptable stone-free rates for treating lithiasis in horseshoe kidneys.
- While complete clearance is not always achieved, ESWL can lead to manageable stone burdens in complex renal anatomies.
