This study aimed to assess the role of pre-designed route on computer tomography
urography (CTU) in the ultrasound-guided percutaneous nephrolithotomy (PCNL) for
renal calculus.From August 2013 to May 2016, a total of 100 patients diagnosed
with complex renal calculus in our hospital were randomly divided into CTU group
and control group (without CTU assistance). CTU was used to design a rational
route for puncturing in CTU group. Ultrasound was used in both groups to
establish a working trace in the operation areas. Patients' perioperative
parameters and postoperative complications were recorded.All operations were
successfully performed, without transferring to open surgery. Time of channel
establishment in CTU group (6.5?±?4.3?minutes) was shorter than the control group
(10.0?±?6.7?minutes) (P?=?.002). In addition, there was shorter operation time,
lower rates of blood transfusion, secondary operation, and less establishing
channels. The incidence of postoperative complications including residual stones,
sepsis, severe hemorrhage, and perirenal hematoma was lower in CTU group than in
control group.Pre-designing puncture route on CTU images would improve the
puncturing accuracy, lessen establishing channels as well as improve the security
in the ultrasound-guided PCNL for complex renal calculus, but at the cost of
increased radiation exposure.
