Purpose Of Review:
Miniaturized PCNL (mi-PCNL) for stone disease is performed under a general anesthesia. However, the role of loco-regional anesthesia in mi-PCNL and its outcomes are not well defined yet. Here, we review the outcomes and complications of loco-regional anesthesia for mi-PCNL. A Cochrane-style review was performed in accordance with the preferred reporting items for systematic reviews to evaluate the outcomes of loco-reginal anesthesia for URS in stone disease, including all English language articles from January 1980 and October 2021.
Recent Findings:
Ten studies with a total of 1663 patients underwent mi-PCNL under loco-regional anesthesia. The stone-free rate (SFR) for mi-PCNL under neuro-axial anesthesia ranged between 88.3 and 93.6%, while it ranged between 85.7 and 93.3% for mi-PCNL under local anesthesia (LA). The conversion rate to another anesthesia modality was 0.5%. The complications ranged widely between 3.3 and 85.7%. The majority were Grade I-II complications and none of the patients had grade V complications. Our review shows that mi-PCNL under loco-regional anesthesia is feasible with good SFR and a low risk of major complications. The conversion to general anesthesia is needed in a small minority, with the procedure itself being well tolerated and a big step towards establishing an ambulatory pathway for these patients.
Insights
Loco-regional anesthesia is a feasible option for mini-percutaneous nephrolithotomy (mi-PCNL), offering good stone-free rates and low major complication risks. This approach supports the development of ambulatory pathways for kidney stone treatment.
Area of Science:
- Urology
- Anesthesiology
- Nephrology
Background:
- Miniaturized percutaneous nephrolithotomy (mi-PCNL) is typically performed under general anesthesia.
- The efficacy and safety of loco-regional anesthesia for mi-PCNL require further definition.
Conclusions:
- mi-PCNL under loco-regional anesthesia is a viable procedure with favorable stone-free rates and minimal major complications.
- This anesthesia approach is well-tolerated, with rare conversions to general anesthesia, paving the way for ambulatory mi-PCNL.
