Abstract

Objective: The pathology of urethral stricture disease is still unclear however progressive inflammationmay contribute to the development of urethral stricture. The platelet-to- lymphocyte ratio (PLR) is a newand simple marker that indicates inflammation. In this study we aimed to investigate the predictive value ofneutrophil to lymphocyte ratio (NLR) and PLR in patients with urethral stricture who underwent transurethralresection of prostate (TURP).Material and methods: A total of 208 patients who underwent bipolar-TURP were included in this study.Patients who had previously undergone surgery due to any urethral pathology, posterior urethral strictures,previous or ongoing treatment for any cancer, hematologic disorders, presence of an active infection at thetime of surgical intervention, and prior blood transfusion were excluded. PLR, NLR and red cell distributionwidth (RDW) levels were measured. In order to investigate the predictive values of NLR and PLR variables,binary logistic regression analysis was performed.Results: No statistically significant differences were observed between the groups in terms of age, NLR,RDW, prostate size and operative times. Statistically significant differences were presented only in the medianPLR- values. For predicting urethral stricture, the optimal cut-off value was 112.5, (sensitivity: 0.84,specificity: 0.64; AUC=0.762, 95% CI 0.684-0.84).Conclusion: In this study we showed that PLR can be used to determine urethral stricture as a cost-effective,common, and simple biomarker in patients after TURP.

Özet

Amaç: Üretral darlığın patolojisi tam olarak açıklanamamasına rağmen progresif inflamasyonun üretral darlığın meydana gelmesinde etkisi olabilir. Trombosit Lenfosit Oranı (PLR) inflamasyonu gösteren yeni ve basit bir markerdır. Bu çalışmada PLR ve Nötrofil-Lenfosit Oranı (NLR)’ (nın) prediktif değerini ve transüretral prostat rezeksiyonu (TURP) operasyonu sonrasında üretral darlığı olan hastalarda PLR’yi ölçmeyi amaçladık. Gereç ve yöntemler: Toplam 208 hasta bu çalışmaya dahil edildi. Daha önce üretral patoloji nedeniyle herhangi bir operasyon geçiren hastalar, posterior üretral darlığı olan hastalar, herhangi bir kanser tedavisi gören hastalar, hematolojik rahatsızlıkları olan hastalar, cerrahi müdahale esnasında aktif enfeksiyonu olan hastalar ve kan transfüzyonu gereken hastalar çalışmadan çıkartıldı. PLR, NLR ve kırmızı küre dağılım genişliği (RDW) değerleri ölçüldü. NLR ve PLR’nin prediktif değerini ölçmek için ikili lojistik regresyon analizi kullanıldı. Bulgular: Yaş, NLR, RDW, prostat büyüklüğü ve operasyon süreleri arasında anlamlı fark bulunmadı. İstatiksel olarak anlamlı fark yalnızca ortanca PLR değerlerinde gösterildi. Üretral darlık için optimal cut-off değeri 112,5 olarak değerlendirildi (sensivite 0,84, spesifite 0,64; AUC=0,762, %95 CI 0,684-0,84). Sonuç: Bu çalışmada PLR’nin TURP sonrasında hastalarda üretral darlık gelişmesini değerlendirmede maliyeti uygun ve basit biyomarker olarak kullanılabileceğini gösterdik.
