Recently, there has been a considerable increase in the
number of procedures carried out under regional anesthesia.
However, percutaneous nephrolithotomy (PCNL) procedures are
usually performed under general anesthesia. The aim of this study
was to assess the safety and efficacy of PCNL under spinal anesthesia
in patients with renal calculi. We describe our 9 years experience of
performing PCNL under spinal anesthesia for 387 patients with large
stones of the upper urinary tract, with regard to the effectiveness and
side effects. All patients received spinal anesthetics (Lidocain 5%, or
Bupivacaine 0.75%) and underwent PCNL in prone position. The
success rate was 94.1%. The incidence of complications was 11.6%.
PCNL under spinal anesthesia is feasible, safe, and well-tolerated in
management of patients with renal stones.
