Key Takeaway
Consider office-based TULA as a feasible, safe, cost-effective alternative for selected patients with small recurrent low-grade NMIBC.

This retrospective cohort study included 53 patients undergoing their first office-based transurethral laser ablation (TULA) for recurrent non-muscle invasive bladder cancer (NMIBC). The intervention utilized a holmium-YAG laser under local anesthesia at a University Hospital Centre Zagreb, office-based setting, with transurethral resection serving as the comparator. The median patient age was 68 years; 54.7% were male, 94.3% had pTa tumors, 92.5% were low-grade, and 90.6% measured less than 3 cm.

The study assessed feasibility, safety, and early oncological outcomes. The procedure was described as highly feasible, safe, and cost-effective with acceptable oncological safety. However, early recurrence rates were notable in this high-risk cohort, and male gender may predict early recurrence.

Safety data regarding adverse events, serious adverse events, discontinuations, and tolerability were not reported. Key limitations include the single-center experience and the high-risk nature of the cohort. The authors note a need for further investigation in larger prospective studies. Practice relevance suggests office-based TULA is a highly feasible, safe, and cost-effective alternative for selected patients with small recurrent low-grade NMIBC, offering significant procedural and economic advantages over transurethral resection.

To evaluate the feasibility, safety, and early oncological outcomes of office-based transurethral laser ablation (TULA) for recurrent non-muscle invasive bladder cancer (NMIBC). We retrospectively reviewed 53 patients undergoing their first TULA for recurrent NMIBC at the University Hospital Centre Zagreb from March 2024 to February 2025. Inclusion criteria comprised histologically confirmed NMIBC recurrence suitable for outpatient laser ablation. Exclusion criteria included carcinoma in situ, muscle-invasive disease, prior intravesical therapy, or tumors >3 cm. Procedures were performed under local anesthesia using a holmium-YAG laser. Clinical, procedural, and oncological outcomes were analyzed, with predictors of recurrence assessed via multivariate logistic regression. The median patient age was 68 years, and 54.7% were male. Most tumors were pTa (94.3%) and low-grade (92.5%); 90.6% measured Office-based TULA is a highly feasible, safe, and cost-effective alternative for selected patients with small recurrent low-grade NMIBC, offering significant procedural and economic advantages over transurethral resection. Although early recurrence rates are notable in this high-risk cohort, oncological safety appears acceptable. Male gender may predict early recurrence, warranting further investigation in larger prospective studies.
