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.
ABSTRACT
Objective To assess the efficacy of submucosal injection of thiotepa for the prevention of recurrence of superficial bladder cancer. Methods Sixty-six patients with superficial bladder cancer were chosen, they were randomly divided into injection group(33 cases)and control group(33 cases). In injection group, 33 patients had submucosal injection of thiotepa, after 30 minutes resection of bladder tumor were treated by PKRBt, after one week, they were given perfusion 27 mg BCG. In control group, 33 patients after the PKRBt were given perfusion BCG. Results The recurrence rate in injection group was 15.2%, and that of the control group was 27.3%. There was significant difference between the twO group (P<0.05). Con-clusions The submucosal injection of thiotepa , PKRBt and perfusion BCG could prevent tumor recur-rence,it has the following advantage,such as simple , safe, less side effect ,more economical. The submu-cosal injection is a practical method to prevent tumor recurrence and is worth popularizing.
