Abstract
Objective To investigate the causes of misdiagnosis of carcinoma in situ(CIS)of the urinary bladder and its preventive measures.Methods The clinical data of 4 patients with CIS of the urinary bladder who had been misdiag-nosed in our hospital from October 2019 to October 2022 were retrospectively analyzed.Results In this group,2 patients showed repeated frequency and urgency of urination for more than 6 months,which was aggravated for 1 week,accompanied by a small amount of hematuria.One patient presented with dysuria for more than 2 months,and one patient presented with dysuria for more than 3 years and urinary tract irritation for more than 10 months after electroprostatectomy.The initial diagno-sis was chronic cystitis in 2 patients,urethral infection and prostatitis in 1 patient.The duration of misdiagnosis was(10.34±2.26)weeks.According to the misdiagnosed diseases,the symptoms were repeated after treatment,and then combined with the characteristics of the disease and urine cytology,cystoscopy and pathological examination,the final diagnosis was CIS of the urinary bladder.Three patients receiving intravesical injection of BCG vaccine combined with electroresection of bladder tumor reported significant improvement in symptoms.They were followed up for 1-3 years,and no recurrence was reported.One patient declined treatment and follow-up.Conclusion CIS of the urinary bladder has no typical clinical manifestations and is more likely to be confused with infectious diseases of the urinary system.Clinicians need to strengthen their understand-ing of this disease,improve their ability of differential diagnosis,and perform relevant medical examination in time to reduce or avoid misdiagnosis and mistreatment.关键词
