RESUMEN
The incidence of inflammatory myofibroblastic sarcoma is low, and bladder origin is more rare. We reported a 58-year-old patient with painless gross hematuria for one week. Total abdominal CT examination showed soft tissue mass in the anterior wall of the bladder, which was considered as bladder cancer, and bladder tumor resection was performed. Postoperative pathology showed inflammatory myofibroblastic sarcoma. Therefore, radical cystectomy was performed because of the high degree of malignancy. There was no recurrence during 3 years follow-up.
RESUMEN
Objective To explore the relationship between oxidative stress and urinary tract infection (UTI) during pregnancy.Methods The urine superoxide dismutase (SOD),catalase (CAT) malondialdehyde (MDA) were measured in 188 pregnant women and 80 healthy women.Results UTI was observed in 39 of 188 pregnant women.The levels of CAT,SOD,and MDA were significantly increased in pregnant women compared to nonpregnant women [(CAT:7.47 ± 0.56) U/ml vs (4.56 ± 0.36) U/ml,P＜0.01 ; SOD:(11.62 ±0.96) U/ml vs (10.25 ±0.89) U/ml,P ＜0.01 ; MDA:(2.46 ±0.22) nmol/mg vs (1.28 ± 0.11) nmol/mg,P ＜ 0.01].The activities of CAT and SOD,and the level of MDA were significantly increased from the first trimester to the third trimester in pregnancy(P ＜ 0.01).The activities of CAT in UTI group [(3.15 ± 0.49) U/ml were significantly lower that the non-UTI group (10.25 ± 0.89)U/ml] (P ＜ 0.01).The activities of SOD in the UTI goup [(4.38 ± 0.37) U/ml were significantly lower than the non-UTI group (13.52 ± 1.11)U/ml] (P ＜0.01).The level of MDA in UTI group [(2.58 ±0.24) nmol/mg] was significantly higher than the non-UTI [(2.43 ±0.21)nmol/mg] (P ＜ 0.01).The rate of UTI (20.74％) in the pregnancy was significantly higher than that in the nonpregnant women (10.00％) (P ＜ 0.05).Conclusions Oxidative stress may be the cause of UTI in pregnant women.
