Extracorporeal shock-wave lithotripsy in patients with spinal cord dysfunction

Area of Science:

• Urology
• Nephrology
• Spinal Cord Injury Medicine

Background:

• Patients with spinal cord dysfunction (SCD) face a higher incidence of urolithiasis.
• Managing kidney stones in this population presents unique challenges due to potential complications and altered physiology.

Purpose of the Study:

• To evaluate the efficacy and safety of extracorporeal shock-wave lithotripsy (ESWL) for treating urolithiasis in patients with spinal cord dysfunction.
• To assess stone fragmentation, clearance rates, and patient tolerance to ESWL in this specific cohort.

Main Methods:

• A retrospective study analyzing data from patients with spinal cord dysfunction who underwent ESWL.
• Review of treatment parameters, including the number of treatments, average shocks per renal unit, and stone fragmentation.
• Assessment of stone-free status at short-term (3 months) and long-term (5-15 months) follow-up.

Main Results:

• ESWL resulted in good fragmentation of stones in most treated kidneys (12 out of 13).
• None of the patients achieved stone-free status at the three-month follow-up.
• A significant proportion of patients (4 out of 9) with long-term follow-up became stone-free between five and fifteen months post-treatment.
• ESWL was generally well-tolerated by the patients.

Conclusions:

• While ESWL provides effective stone fragmentation in patients with spinal cord dysfunction, the stone clearance rate is poor and delayed.
• Further investigation and alternative or adjunctive treatment strategies may be necessary to improve stone-free outcomes in this patient group.
