MATERIAL AND METHODS One hundred and seventy-five infants with kidney stones were included in this study: 105 boys and 70 girls. The median age was 16 months (range, 3–36 months). Sixty-five patients had left- side calculi, 68 of them had right-side calculi, and 42 had bilateral calculi. The median diameter of the calculi was 1.8 cm (range, 1.0–3.2 cm). Retrograde intrarenal surgery was performed by an 8 Fr/30 cm flexible ureterorenoscope (POLY ® ) combined with a holmium laser. CT scanning or radiography of the kidneys, ureters, and bladder (KUB) region was performed one month after the operation to confirm the clearance of calculi. RESULTS All the 175 infants with calculi in 217 sides underwent flexible ureteroscopic lithotripsy. The me- dian operation time was 32 min (range, 10–90 mins). The median amount of flushing fluid was 550 mL (range, 100–1400 mL). The stone-free rate after a single session treatment was 92.2 % (200/217), within which 15 infants underwent simultaneous bilateral flexible ureteroscopy lithotripsy. Catheters were retained for 24–48 hours after the operation. Continuous high fever due to reflux (39–40°C, 3–5 days) was present in seven cases. Flushing fluid extravasation was found in two infants. Some patients with minor complications, such as mild hematuria, irritation symptoms, and low fever, recovered without treatment. The duration of hospitalization time after the operation was approximately 1–7 days. CONCLUSIONS Flexible ureteroscopic lithotripsy is a safe, highly efficient, minimally invasive, and reproducible operation for removal of renal calculi in infants. This technique is a convenient method for postop- erative management of patients that enhances their rapid recovery.
