Abstract:
Objective To evaluate the safety and efficacy of colour doppler in guiding the percutaneous nephrolithotomy(PCNL) for Staghom calculi.Methods The clinical records of 46 patients with renal calculi who underwent PCNL were retrospectively analyzed.Patients' mean age was 43 years old,and the range of diameter of stone was 3.0 -7.5 cm.Among these cases,29 cases had complete staghorn calculus.One case had isolated kidney stone.And the other 6 patients had open surgery history.Using Colour Doppler guidance,the percutaneous nephrolithotomy for renal calculi was conducted.Results F22 percutaneous channel was successfully established in 55 sides of 46 patients,with the first and the second phase surgeries of 41 and 14 sides respectively.Single-,double- and three-channel PCNL were performed in 38,16,and 1 sides respectively.Abdominal x-ray conducted at 3 -4 days post operation revealed residual stones on 18 sides,with the range of 0.4 -2.0 cm in diameter.Second-phase lithotripsy was conducted on 14 sides of patients.After the first and the second phases of surgery,4 sides having residual stones ranging 0.6 - 1.0 cm,underwent extracorporeal shock wave lithotripsy.Ater the third-phase surgery,the diameters of residual stones were much less than 0.5 cm and patients were treated with medication.The total rate of clearance was 87.0％ (48/55).The duration of surgery was 65 - 160 minutes and 95 minutes on average.One patient having delayed bleeding was cured with selective renal artery embolization.There were no complications such as nephrectomy,deaths,pleural or intestinal damage during the period of study.Patients were followed up for 3 to 18 months.Six of 9 patients with renal insufficiency recovered after surgery.The serum creatinine in the remaining 3 patients ranged 185 -220 μmol/L Conclusion Colour Doppler-guided percutaneous nephrolithotomy for renal calculi is safe and effective.
