Safety and feasibility of single-port nephroscopy combined with a needle electrode technique to treat dorsal SRCs.

Objective The aim of this study was to explore the safety and feasibility of single-port nephroscopy combined with a needle electrode technique to unroof single dorsal simple renal cysts (SRCs). Methods This was a retrospective analysis of the clinical data for 18 patients with single dorsal SRCs treated with single-port nephroscopy and a needle electrode technique at Zhongshan City People's Hospital from August 2021 to August 2022. The basic information included the cyst condition, surgical methods and recurrence rate, and follow-up was conducted with CT imaging. Results The surgery was successful in all 18 patients. The duration of surgery ranged from 24-46 minutes, with an average of 35.83±1.62 minutes; the intraoperative bleeding volume ranged from 2-20 ml, with an average of 9.0±1.3 ml; and the visual analog scale (VAS) score within 24 hours after surgery ranged from 1-6 points, with an average of 2.72±0.36 points. There were no significant postoperative complications, such as bleeding, urinary fistula, or infection. All drainage tubes were removed on the first day after surgery. After 1 year of postoperative follow-up, one patient experienced recurrence, for a recurrence rate of 5.6%. Conclusion Single-port nephroscopy combined with a needle electrode technique is a safe, feasible, and effective minimally invasive surgical approach for treating single dorsal SRCs.
