Abstract:
Objective To explore the efficacy and safety of treatment of intramural ureteral tumors via transurethral resection. Methods A retrospective analysis was conducted on the clinical data of 26 patients with ureteral cancer who underwent transurethral resection of intramural ureteral tumors at the First Affiliated Hospital of Naval Medical University from May 2020 to May 2023. All patients were treated using the “outer-wedge, inner-rotation” resection technique, with ureteral stents placed intraoperatively. Clinical indicators including operation time, intraoperative blood loss, length of postoperative hospital stay, ureteral stent indwelling duration, intraoperative and postoperative complications, postoperative pathological results, and bladder tumor recurrence rate were analyzed. Results All surgeries were successfully completed. The operation time was 45(35, 60) min, intraoperative blood loss was 5(3, 10) mL, length of postoperative hospital stay was 4(3, 5) d, and the ureteral stent indwelling duration was (33.8±9.7) d. All patients did not experience intraoperative complications, the postoperative hydronephrosis rate was 3.8%. Postoperative pathology confirmed urothelial carcinoma in all cases, including 6 cases of stage pTa, 16 cases of pT1, and 4 cases of pT2a. The follow-up period ranged from 12 to 48 months. Intravesical recurrence occurred in 2 patients, and recurrence rate was 7.7%. There were no tumor-related deaths during the follow-up period. Conclusions Transurethral resection of intramural ureteral tumors is minimally invasive, resulting in less blood loss, and has low rates of postoperative complications such as hydronephrosis and hydroureter. It achieves favorable surgical outcomes while better preserving renal function.
