Abstract:
Objective To explore the risk factors ,prevention and treatment of the occurrence of perirenal hematoma after flexible lithotripsy. Methods We retrospectively analyzed the clinical data of 18 patients with symptomatic perirenal hematoma from 1259 who had undergone ureteral flexible lithotripsy in our hospital during the period of April 2007 to April 2016. Of the 18 patients,7 were complicated with diabetes mellitus,11 had urinary tract infection;15 were female,and 3 were male. Results Perirenal hematoma was confirmed by B ultrasound and CT,which situated on the Posterolateral side of the kidney in 8 patients,and on the lower pole and abdominal side in 10. Hematoma depth was 2.6-15.3 cm(average was 5.2 cm). The hematoma?related symptoms gradually disappeared in 11 patients 7 to 14 days after they received conservative treatment. 5 recovered gradually 15 days after undergoing hematoma puncture and drainage ,and 2 recovered 36 days after receiving open surgery for removal of hematoma. Conclusions Female,diabetes,urinary tract infection,bigger stone size,prolonged surgical duration,and infected stones were the risk factors for perinephric hematoma related to ureteroscopic lithotripsy. Full preoperative preparation ,effective anti?infection ,intraoperative improvement of calculus?breaking skills and use of large caliber semirigid through sheath,low pressure perfusion,shorter surgical duration,and staging surgery are effective ways to reduce the occurrence of perirenal hematoma.
