115.9 joules, p = 0.005) were significantly less in the group undergoing HFJV compared to the group undergoing CMV.
Postoperatively, patients undergoing HFJV spent slightly less time in the postoperative recovery area, but this was not significantly different from the CMV (95.8 minutes vs.
Warner and colleagues in 1988 were the first to investigate the potential benefits of HFJV for SWL.[sup.6] They found that mean stone movement and mean total shocks were significantly decreased during HFJV compared with CMV.
We found that the group undergoing HFJV during SWL with the Seimens[R] Lithostar Modularis, a third-generation lithotripsy machine, required significantly less total shocks (3754 vs.
Given that the HFJV group required less total shocks, one might have expected to find the group undergoing HFJV would enjoy decreased operating room time.
