Objective: We aimed to understand the practices of Turkish urologists using intravesical onabotulinum toxin-A (BoNT-A) injections for refractory overactive bladder (OAB) and neurogenic lower urinary tract dysfunction (NLUTD) treatment, focusing on pre, peri, and postoperative management. We also explored the potential influence of functional urology workload on these practices. Material and Methods: A cross-sectional survey was circulated via the Turkish Association of Urology's WhatsApp group, collecting data on practices and preferences related to BoNT-A treatment. Statistical analysis was performed for comparisons between categorical groups. Results: 65 urologists participated. Most targeted population was NLUTD patients (40%). Preoperatively, spinal or general anesthesia was the preferred method (55.4%). For perioperative prophylaxis, second-generation antibiotics were popular (43.1%). BoNT-A dosage typically was 100 units for first OAB application (92.3%), while 200 units for first NLUTD application (70.8%). The injection site was usually the detrusor (44.6%), with most refraining from trigone injections (63.1%). Respondents with the functional urology workload >25%, favored 300 units for the first NLUTD application (p=0.009), trigone injections (p<0.001), and a second application between 3-5 months (p=0.016). Conclusion: Significant variations have been identified in the usage of BoNT-A for the treatment of OAB and NLUTD by Turkish urologists, largely influenced by the functional urology workload. Understanding these differences will help refine treatment strategies and highlight the need for more research and more specific guidelines.

Amaç: Bu çalışmada, Türk ürologlarının dirençli aşırı aktif mesane (AAM) ve nörojenik alt üriner sistem disfonksiyonu (NAÜSD) tedavisinde intravezikal onabotulinum toksin-A (BoNT-A) enjeksiyonlarında pre, peri ve postoperatif yönetimindeki yönelimlerinin tespit edilmesi amaçlandı. Ayrıca, fonksiyonel üroloji iş yükünün bu uygulamalar üzerindeki potansiyel etkisi de araştırıldı. Gereç ve Yöntemler: Türk Üroloji Derneğinin WhatsApp grubu aracılığıyla, BoNT-A tedavisi ile ilgili uygulamalar ve tercihler hakkında veri toplayan kesitsel bir anket uygulandı. Kategorik gruplar arasındaki karşılaştırmalar için istatistiksel analiz yapıldı. Bulgular: Çalışmaya 65 ürolog katıldı. En çok hedeflenen popülasyon NAÜSD hastalarıydı (%40). Preoperatif olarak spinal veya genel anestezi tercih edilen yöntemdi (%55,4). Perioperatif profilaksi için en fazla tercih edilen ikinci kuşak antibiyotiklerdi (%43,1). BoNT-A dozajı tipik olarak ilk AAM uygulaması için 100 ünite (%92,3), ilk NAÜSD uygulaması için 200 ünite (%70,8) idi. Enjeksiyon bölgesi genellikle detrusordu (%44,6) ve katılımcıların çoğu trigon enjeksiyonundan (%63,1) kaçınıyordu. İş yükü >%25 olan katılımcılar, ilk NAÜSD uygulaması (p=0,009), trigon enjeksiyonları için (p<0,001) ve 3-5 ay arasında ikinci bir uygulama (p=0,016) için 300 üniteyi tercih ettiler. Sonuç: Türk ürologlar tarafından AAM ve NAÜSD tedavisi için BoNT-A kullanımında, büyük ölçüde fonksiyonel üroloji iş yükünden etkilenen, önemli farklılıklar belirlenmiştir. Bu farklılıkları anlamak, tedavi stratejilerini iyileştirecek ve daha fazla araştırmaya ve daha kesin kılavuzlara olan ihtiyacı vurgulayacaktır.
