Abstract:Purpose:To assess the advantage of urine drainage by double-J ureteral stent or by percutaneous indwelling stent for upper urinary lithotomy. Methods: The therapeutic effect of 46 patients with internal stent and 52 with external stent for upper urinary lithotmy were analysed retrospectively. Results: Hospitalized course and duration of retroperitoneal indwelling in the internal drainage group was notably less than those in the external drainage group. The total postoperative complication rate in the internal drainage group was also remarkably lower than that of the external drainage group. Conclusions: It is suggested that double-J stent is more effective and safer than percutaneous indwelling stent. However, Percutaneous indwelling stent or both used simultaneously will be more safer in the condition of renal insufficiency, obstruction of lower urinary and inflammation.
