Abstract

Objective With the use of flexible ureter in kidney stone disease and the unique cutting function of holmium laser, some clinicians have used holmium laser under ureteroscope for one-stage treatment of parapelvic cyst complicated with renal calculi (PCCRC). The purpose of this article is to further explore the safety and clinical effect of this operation. Methods To retrospectively analysis the clinical data of 9 patients in our hospital, who were diagnosed with PCCRC and treated with combined flexible ureteroscope in the same phase. Results All 9 patients were successfully operated at one time, and the operation time was 23-45 min, with an average of 32 min. There were no complications such as massive hemorrhage or septic shock during or after the operation. After the follow-up period of 1-12 months, all the cysts were reduced or disappeared, and the stones were completely re-moved or just no clinical significance stones remains. Conclusions Using the combined flexible ureteroscopein the treatment of the PCCRC can achieve satisfactory clinical efficacy and is worthy of being further applied and discussed by clinicians.
