- Abstract:
- Objetive To investigate the utility of CT urography (CTU) reconstruction in preoperative of minipercutaneous nephrolithotomy under typeB ultrasound guidance in the treatment of complex renal calculi.MethodsThe 24 cases of complex renal calculi in patients with minimally invasive minipercutaneous nephrolithotomy line lithotripsy application of CT urography in the preoperative threedimensional reconstruction techniques to learn the location of kidney stones， shapes， position or direction of the branches of stones. and hydrocalyx etc.， to determine the puncture point， puncture angle and depth. to provide the best path for puncture. and the accuracy and effectiveness of 29 cases not underwent CTU was retrospective analysis.ResultsIn the 24 cases， CTU provided an advantage over conventional imaging in optimizing nephrostomy placement. All the case were punctured successfully. Stonefree rate was 100%，and total stonefree rate reached 79.4%.， all without blood transfusion， none of abdominal organs and pleural was injured.The stonefree at 1 session was significantly increased than group of not underwent CTU.ConclusionCT urography reconstruction technique evaluate in preoperative of minipercutaneous nephrolithotomy. Work out an advantage over conventional imaging in optimizing nephrostomy placement and decreases potential hazards in placing the track. MPCNL can be safe and effective， high stonefree rate and low complications with CTU.
