Objective: To evaluate the early results of endoscopic bipolar transurethral resection (Bi-TUR) of non-muscle invasive bladder cancer (NMIBC) at Viet Tiep Hospital. Patients and methods: This study included 33 patients diagnosed with NMIBC who were treated with Bi-TUR at Viet Tiep Hospital between April 2022 and August 2023. Results: The mean age was 66.8 ± 11.4 years, the youngest was 40 years, and the oldest was 87 years. The male-to-female ratio was 5.6/1. The most common location of the tumor was the lateral wall in of 24/33 patients, accounting for 72.7%. The mean operation time was 45.1 ± 9.5 minutes. Among the 33 patients, 30 (90.9 %) had no complications. One patient had postoperative bleeding, accounting for 3%, and two patients had urinary tract infections, accounting for 6.1%. Evaluation of the surgical results after surgery showed that 30/33 patients achieved good results. Three patients achieved fair results. The most common histological type was transitional cell carcinoma in 32/33 patients, accounting for 97%. Conclusion: The Bi-TUR for NMIBC is safe and effective, reducing many intraoperative and postoperative complications.
