Objectives
To determine whether percutaneous nephrolithotomy (PCNL) can be safely performed in the high-risk patient.Methods
The records of 84 patients undergoing 98 consecutive PCNL procedures from January 2005 to January 2007 at a single institution were examined. Patients were divided into a high-risk preoperative group, which comprised patients having American Society of Anesthesiologist scores of III or IV (n = 25) and a low-risk preoperative group of patients with an American Society of Anesthesiologist score of II or less (n = 59).
Results
A total of 33 and 65 procedures were performed in the high- and low-risk groups, respectively. The high-risk group had significantly more comorbidities than the low-risk group (5.4 vs 1.5) (P <.001). No significant difference was noted in the mean cumulative stone size for single or multiple stones in either group. A significant difference was observed between the average anesthesia time (45 vs 25 minutes) and average length of hospital stay (4.0 ± 3.5 vs 2.7 ± 1.2 days) but no significant difference in estimated blood loss (132 vs 150 mL) or mean operative time (118 vs 100 minutes) between the high- and low-risk groups, respectively. The overall complication rate was similar between the high-risk (12.1 % ) and low-risk (12.3 % ) groups (P = .41). The stone-free rate for the high-risk group was 61 % compared with 92 % for the low-risk group (P = .028).
Conclusions
PCNL can be safely performed in the high-risk preoperative patient population.
