Simultaneous antegrade-retrograde stone therapy, combining percutaneous nephrolithotomy (PCNL) and flexible ureterorenoscopy (fURS), offers an effective minimally invasive option for complex kidney stones. This approach addresses challenging cases but requires specialized expertise and equipment.
Area of Science:
- Urology
- Minimally Invasive Surgery
- Nephrolithiasis Treatment
Context:
- Percutaneous nephrolithotomy (PCNL) is the standard for large kidney stones.
- Complex stones often require multiple procedures or open surgery.
- Simultaneous antegrade-retrograde therapy is an emerging alternative.
Purpose:
- To evaluate the efficacy of combining PCNL with flexible ureterorenoscopy (fURS) for complex kidney stone management.
- To explore the advantages and challenges of simultaneous antegrade-retrograde stone therapy.
Summary:
- Flexible ureterorenoscopy (fURS) accesses narrow calyces, while PCNL removes stones via the percutaneous shaft.
- This combined approach effectively treats complex and large kidney stone burdens.
- Challenges include increased personnel/instrumentation needs and a learning curve with the supine lithotomy position.
Impact:
- Simultaneous antegrade-retrograde therapy provides an effective minimally invasive solution for difficult stone situations.
- Successful implementation requires appropriate equipment and surgical expertise.
- This technique expands minimally invasive options beyond traditional PCNL for complex nephrolithiasis.
