Abstract:
Objective: To investigate the clinical efficacy of en bloc resection of ureteral orifice in the treatment of tumors around ureteral orifice. Methods: Clinical data of 43 patients treated at our hospital during Jul.2018 and Jun.2023 were retrospectively analyzed，including 34 male and 9 female patients.Prior to surgical intervention，all patients were diagnosed with bladder masses via imaging or cystoscopy，and no concurrent upper urinary tract tumors were detected.The initial surgical procedure was transurethral resection of bladder tumor，which removed the tumors around ureteral orifice.Subsequently，electrocoagulation was employed for hemostasis，followed by the placement of a double-J tube into the affected ureter.Tumor recurrence and hydronephrosis were observed after operation. Results: All operations were successful without conversion to open surgery.The operation time was (61±25) min.The postoperative pathological results showed 28 cases of Ta stage tumors，14 cases of T1 stage tumors，and 1 case of T2 stage tumor.During the follow-up of (17±11) months，8 patients (19%) had tumor recurrence，among whom 4 (9%) had recurrent tumor involving the ureteral orifice，and 1 (2%) had transient hydronephrosis after removal of double-J tube. Conclusion: The en bloc resection of the ureteral orifice with placement of a double-J tube is safe and effective for the treatment of tumors around the ureteral orifice，with low recurrence rate.It is an optional procedure for early stage patients.
