Abstract：Objective: To evaluate the efficacy of electronic fexible ureteroscopy holmium laser lithotripsy in treating renal stones in a solitary kidney. Methods: From March 2012 to August 2014, 12 patients with a solitary kidney underwent electronic fexible ureteroscopy holmium laser lithotripsy. All patients received computed tomography to understand the location and size of the stones preoperatively. Preoperative urine culture were done and positive patients were treated by sensitive antibiotics for three days. F7 double-J tube were inserted in all patients to dilate the ureter for 2 weeks preoperatively. Factors such as operation duration, complications and stone-free rate (SFR) were analysed. Results: The mean age was 64 years (range, 21-73 years). The mean stone size was (2.1±0.6)cm (range 1.6-3.2 cm). The mean operation time was 117 min (range 40-200 min). The SFRs was 83.3%. Systemic Inflammatory response syndrome and urosepsis were respectively recorded in one patient and cured after active treatment. After one month follow-up, the preoperative and postoperative serum creatinine had statistical difference (P＜ 0.05). Conclusions: Electronic fURS holmium laser lithotripsy is an effective and safe procedure with a high SFR and a lower rate of complication in treating renal stones in a solitary kidney.
