Treatment of ureteral calculi complicated by upper urinary tract infections via holmium YAG laser

OBJECTIVE To provide reference for the treatment of ureteral calculi and prevention of complicated infections.METHODS Thirty cases of ureteral calculi complicated with upper urinary tract infection underwent ureteroscopic holmium YAG laser treatment were retrospectively reviewed.RESULTS Lithotripsy was successfully carried out in all the 30 cases with the operation duration ranged 12~60 minutes,averaging 30 minutes.All cases developed varying degrees of microscopic or macroscopic hematuria postoperatively.Movement of residual stones >0.5 cm up to the renal pelvis was noted in 3 cases;ureter perforation,avulsion and other serious complications were noted in none of these cases.Body temperature restored 3~9 days after the operation and results of routine urine test returned to normal 7~12 days later.CONCLUSION Ureteroscopic holmium YAG laser lithotripsy is both effective and reliable for the treatment of ureteral calculi complicated with urinary tract infections and severe infections can be prevented with the proper screening of cases.
