ABSTRACT
Objective:To explore the reliability, availability and security of peel-away plastic film sheath combination of ureteroscopy pneumatic lithotripsy treatment of female lower segment complexity ureteral calculi.Methods: The treatment group(40 cases) used peel-away plastic film sheath establish a bridge sheath channel between the urethra, bladder and the ureteral opening, combining under ureteroscopy pneumatic lithotripsy treatment. The control group(40 cases) with traditional under ureteroscopy pneumatic lithotripsy treatment. The clinical data of two groups of patients were analyzed.Results: The cure rate of the treatment group was significantly higher than the control group(x2=5.54,P<0.05); and the stones operation time, the bleeding, hospital stays and hospital costs was much better than control group; the complications of surgery (except the ureteral perforation) was significantly less than that of control group.Conclusion: Treatment of female lower segment complexity ureteral calculi by using the peel-away plastic film sheath establish a bridge sheath channel between the urethra, bladder and the ureteral opening, combining under ureteroscopy pneumatic lithotripsy treatment, with safe, convenient, practical, low cost, little injury, fewer complications, etc. was worthy of clinical application.
