Abstract：Objective:To investigate the treatment method of lower ureteral stones after orthotopic urinary diversion.Methods:Between February 2003 and July 2012, 9 male patients, with lower ureteral stones after orthotopic urinary diversion were managed with ureteroscopic lithotripsy guided by an antegrade metal guide wire via percutaneous nephrostomy.Results:All operations were successfully completed. The guidewire was smoothly inserted into bladder in 7 patients and stones were smashed with a semi-rigid ureteroscope retrogradely via the urethra. Another two cases were managed with a flexible ureterosope due to failure to place a guidewire to the antegradely. 8 cases were followed up for 3-12 (mean: 8.2) months with KUB、IVU and CT examinations.Stones were completely extracted and hydronephrosis was significantly reduced.Conclusions:Ureteroscopic lithotripsy guided by an antegrade guidewire via a percutaneous nephrostomy provides a new and effective minimally invasive treatment for lower ureteral stones after orthotopic urinary diversion.
