Abstract：Objective To analyze the clinical characteristics,diagnosis,differential diagnosis,causes of misdiagno-sis and preventive measures of vesicosigmoid fistula.Methods From March 2022 to April 2023,the clinical data of 2 pa-tients with vesicosigmoid fistula misdiagnosed as bladder cancer were retrospectively analyzed.Results Two patients were ad-mitted due to rectal mass for 3 d and intermittent gross hematuria for 9 d,respectively.Both patients were misdiagnosed as bladder cancer and underwent transurethral resection of the bladder.The postoperative pathology showed bladder granuloma-tous inflammation and cystitis glandularis.The diagnosis of vesicosigmoid fistula was confirmed following the location of the fis-tula identified by CT plain scan after retrograde injection of contrast agent into the bladder through a urinary catheter.The mis-diagnosis lasted 1 to 2 weeks.One patient underwent open partial resection of sigmoid colon and vesicosigmoid fistula repair.One patient underwent laparoscopic partial resection of sigmoid colon+vesicocolonic fistula repair+partial cystectomy.All patients recovered well after operation and no abnormality was found during follow-up.Conclusion Vesicosigmoid fistula is rare in clinical practice.Several patients are more likely to experience missed diagnosis and misdiagnosis due to lack of specif-ic symptoms,insufficient understanding of clinicians,and limited imaging examination.Clinicians should be highly alert to vesicosigmoid fistula to avoid delay in treatment.
