Abstract:
Objective To evaluate the clinical efficacy and safety of Holmium laser in the treat ment of calyceal stricture and atresia through antegrade percutaneous nephrostomy. Methods Ante grade percutaneous nephrostomy was performed in 68 patients with calyceal stricture and atresiathrough a rigid 8/9.8 F ureteroscope. The stricture and atresia was incised in a linear fashion by theHolmium laser with a 550 mm fiber. After completion of the incision,a double J ureteral stent wasplaced for 6-8 weeks and nephrostomy tube was kept for 7 days thereafter. Patients were then fol lowed up with IVU and/or ultrasound at 3-6 month intervals. Results The mean operative timewas 90 min,ranged from 80 to 120 min. The mean postoperative hospital stay was 8 d(7-9d). Hy dronephrosis was significantly improved in 38 cases in an average follow up of 9 months (4-26 months). Repeated laser incision was performed to 4 treatment failures and all turned out to be suc cessful. Conclusions The Holmium laser treatment through antegrade percutaneous nephrostomyfor calyceal stricture and atresia has characteristics of minimal invasion,short hospital stay,good effi cacy in short term and repeated cases. This procedure to be used as the first choice for patients withgood renal function and mild hydronephrosis,especially accompanied with renal calculus.
