Introduction: Bladder cancer is one of the most common tumors among the general population. The first surgical approach to the tumor is often the transurethral resection with monopolar or bipolar loop. Recently, laser energy has become an alternative for resection of small bladder tumor, because it allows to obtain high quality samples with the “en bloc” technique. Our study aims to show the results of endoscopic diode laser treatment of bladder tumor up to three centimeters in maximum diameter. Materials and methods: 189 patients underwent “en bloc” resection with diode dual length laser (980 nm-1470 nm). Follow up was over 12 months. Patients age range was from 45 to 75 years. Maximum diameter of the lesions was 3.0 cm. For each patient, a cold forceps biopsy sample was performed. Results: All samples collected presented detrusorial layer. Pathological exam showed: 28 (14.8%) Ta, G1-G2; 7 (3.7%) T3, G2-G3; 14 (7.4%) T1, G2-G3 and 140 ( 74.1%) Ta, G2-G3. No complications occurred during or after surgery. At a median follow-up period of 6 months, we had no recurrence in the previous site of tumor. In the follow up at 3/6/12 months in 4 cases we had recurrence in different sites of bladder wall. Conclusions: Laser “en bloc” resection is an effective, feasible, and safe treatment for bladder tumor. It could be a valid alternative to monopolar and bipolar resection in small bladder cancer treatment.

Abstract

Introduction: Bladder cancer is one of the most common tumors among the general population. The first surgical approach to the tumor is often the transurethral resection with monopolar or bipolar loop. Recently, laser energy has become an alternative for resection of small bladder tumor, because it allows to obtain high quality samples with the “en bloc” technique. Our study aims to show the results of endoscopic diode laser treatment of bladder tumor up to three centimeters in maximum diameter. Materials and methods: 189 patients underwent “en bloc” resection with diode dual length laser (980 nm-1470 nm). Follow up was over 12 months. Patients age range was from 45 to 75 years. Maximum diameter of the lesions was 3.0 cm. For each patient, a cold forceps biopsy sample was performed. Results: All samples collected presented detrusorial layer. Pathological exam showed: 28 (14.8%) Ta, G1-G2; 7 (3.7%) T3, G2-G3; 14 (7.4%) T1, G2-G3 and 140 ( 74.1%) Ta, G2-G3. No complications occurred during or after surgery. At a median follow-up period of 6 months, we had no recurrence in the previous site of tumor. In the follow up at 3/6/12 months in 4 cases we had recurrence in different sites of bladder wall. Conclusions: Laser “en bloc” resection is an effective, feasible, and safe treatment for bladder tumor. It could be a valid alternative to monopolar and bipolar resection in small bladder cancer treatment.
