Application of ureteral balloon dilation catheter in treatment of renal calculi without hydronephrosis

Objective To explore the efficacy and safety with ureteral balloon dilation catheter for establishing artificial hydronephrosis in the treatment of renal calculi without hydronephrosis.Methods Ureteral balloon dilation catheter were applied for establishing artificial hydronephrosis in the treatment of 38 cases of renal calculi without hydronephrosis.All the patients underwent puncture by ultrasound guidance to establish percutaneous renal operation channel and holmium laser lithotripsy.All the patients were followed up for(8 ±2) months,and no ureteral stricture was found.Results All patients were successfully established artificial hydronephrosis and punctured to form percutaneous renal operation channel for lithotripsy by one-time.The first stage of lithotripsy was performed successfully in all cases,of which 34 cases without residual stones and 4 cases without residual stones in diameter less than 3 mm in postoperative examination.The average operation time and blood loss was 75 minutes and 20 ml,respectively.No severe complication occurred,such as pneumothorax and injury of abdominal organ.No transfusion and conversion to open surgery is obversed.Conclusions Using ureteral balloon dilation catheter for establishing artificial hydronephrosis in the treatment of renal calculi without hydronephrosis is simple,safe,effective and worth recommending.
