Effect analysis of ureteroscope holmium laser incision in treatment of parapelvic MRI cyst

Objective: To investigate the safety and efficacy of flexible ureteroscopy in treating parapelvic cysts. Methods: From June 2017 to June 2019, 21 cases of parapelvic cysts were treated by flexible ureteroscopy with holmium laser incision in our hospital. The average diameter of the cyst was (6.1 +/- 1.6) cm. All patients were treated with flexible ureteroscopy with holmium laser incision and drainage of the cyst wall, and 4.7F ureteral stent was indwelling for 3 months after operation. The patients were followed up for an average of 2 years to observe the clinical efficacy and safety. Results: The intraoperative blood loss and postoperative pain scores of the observation group were significantly better than those of the control group, the operation time and hospitalization time of the observation group were significantly shorter than those of the control group, and the postoperative recurrence rate of the observation group was significantly lower than that of the control group, with statistically significant differences (P < 0.05). Conclusion: The incision and drainage of the parapelvic cyst under a flexible ureteroscope can effectively reduce the intraoperative bleeding and postoperative pain of patients, and the postoperative recovery is fast, there is less recurrence, it is safe and reliable, and it is worthy of promotion.
