Abstract:
Objective To evaluate the clinical efficacy of Memotherm TM stent,a type of metallic stent in the management of secondary ureteropelvic junction obstruction. Methods From October 1995 to June 2001,13 cases (10 males and 3 females,mean age of 41 years) of secondary ureteropelvic junction obstruction underwent the Memotherm TM stenting.They were all followed up for an average of 26 months by B ultrasound,IVU,radionuclide renography and ureteroscopy. Results Of the 13 case,8 were cured,and 3 achieved improvement,while 2 cases failed.The main complications of endoprosthetic fibrotic stricture occurred in 5 cases.The forceps or YAG laser through ureteroscopy was used to remove the endoprosthetic fibrotic tissues. Conclusions Memotherm TM stent is mostly effective in the treatment of patients with secondary ureteropelvic junction obstruction,especially for patients who has undergone multiple operations or those are ineligible for open surgery.This procedure can significantly reduce the recurrence of ureterostenosis.
