Abstract

Abstract:

Objective

To evaluate the safety and clinical efficacy of flexible ureteroscopy (RIRS) with holmium laser incision for treatment of renal parapelvic cyst.

Methods

32 cases with renal parapelvic cyst after RIRS with holmium laser incision from September 2017 to July 2020 were reviewed.There were 21 males and 11 females and the age was 35-68 years. The size of parapelvic cyst ranged from (3.5 cm×3.0 cm) to (7.0 cm×5.0 cm), mean (5.0±0.8) cm. All cases were unilateral parapelvic cyst (Bosniak Ⅰ cysts were in 29 cases and Bosniak Ⅱ in 3 cases). In which, 24 cases got single cysts, 5 cases got multiple cysts, 1 polycystic kidneys and 2 cases with renal calculi. There were 8 cases with hydronephrosis of different degrees. Preoperative and postoperative cyst changes, operation time, postoperative hospital stay, complications were analyzed.

Results

All surgeries were performed successfully. Operation time was 22-68 min, mean (43±12) min. The postoperative hospital stay was 3-6 (3.8±0.7) days. After follow-up of 3-6 months, the cysts disappeared in 22 patients and size reduced in 9 patients. There was no obvious change in 1 patient of polycystic kidney cyst after operation. Hydronephrosis disappeared in 8 patients. Complication occurred in 6 patients (18.75%), 5 were Clavien Ⅰ grade and 1 was Clavien Ⅱ grade.

Conclusions

Flexible ureteroscopy with holmium laser incision is a safe and effective method for the treatment of parapelvic cyst, but the long-term efficacy needs further follow-up observation.

Key words: Renal parapelvic cyst, Flexible ureteroscopy, Holmium laser
