Amaç: Bu çalışmanın amacı daha önce endoskopik üst üriner sistem cerrahisi geçiren hastalarda üreter darlığı veya zor/sıkı üreter gelişim riskini öngörmede, nötrofil/lenfosit oranı (NLO) ve platelet/lenfosit oranı (PLO)’nın etkinliğini araştırmaktır.
Gereç ve Yöntemler: Bu gözlemsel çalışma Nisan 2022 ile Nisan 2023 tarihleri arasında Samsun Eğitim ve Araştırma Hastanesi, Üroloji Kliniği’nde yapılmıştır. Çalışmaya daha önce endoskopik üst üriner sistem cerrahisi geçiren 130 hasta alınmıştır. Hastalar üreter darlığı olanlar (Grup 1) ve olmayanlar (Grup 2) olmak üzere iki gruba ayrılmıştır. Üreter darlığı direk endoskopik olarak veya retrograd piyelografi ile konulmuştur. Grupların sosyodemografik özellikleri, klinik verileri, NLO ve PLO değerleri karşılaştırılmıştır.
Bulgular: Çalışmaya alınan hastaların yaş ortalaması Grup 1’de 49,89 ± 14,40 ve Grup 2’de 48,92 ± 14,60 yıl olarak bulundu (p = 0,704). Vücut kitle indeksi, cinsiyet, hidronefroz, komordite açısından gruplar arasında istatistiksel olarak fark izlenmezken; taş düşürme öyküsü ve geçirilmiş operasyon sayısı açısından anlamlı fark izlendi (sırasıyla p = 0,001 ve p <0,001). Grupların NLO değeri sırasıyla 2,62 (0,75-9,18) ve 2,29 (0,80-6,67); PLO değeri 136,57 (55,02-475,45) ve 118,66 (37,50-244,17) olarak bulundu. Her iki değer karşılaştırıldığı zaman gruplar arasında fark izlenmedi (sırasıyla, p = 0,139 ve p = 0,076).
Sonuç: Çalışmamızda NLO ve PLO değerleri üreter darlığı olan grupta daha yüksek tespit edilmesine rağmen bu yükseklik istatistiksel olarak anlamlı bulunamamıştır. Bizim çalışmamıza göre daha önce endoskopik üst üriner sistem cerrahisi geçiren hastalarda üreter darlığı gelişmesini öngörmede NLO ve PLO değerlerinin etkisi yoktur.

Can the Neutrophil/Lymphocyte Ratio and Platelet/Lymphocyte Ratio Be Used to Predict the Risk of Ureteral Stricture Following Ureteroscopy?

Öz

Objective: The purpose of this study was to investigate whether the neutrophil/lymphocyte ratio (NLR) and platelet/lymphocyte ratio (PLR) can be used to predict the development of ureteral stricture or difficult ureter in patients who had previously undergone endoscopic upper urinary tract surgery.
Material and Methods: This observational study was performed between April 2022 and April 2023 at the Samsun Training and Research Hospital Urology Department, Türkiye. One hundred thirty patients who had undergone prior endoscopic upper urinary tract surgery were included. These were divided into two groups, with (Group 1) and without (Group 2) ureteral stricture. The diagnosis of ureteral stricture was based on direct endoscopy or retrograde pyelography. The groups’ sociodemographic characteristics, clinical data, and NLR and PLR values were then compared.
Results: The patients’ mean ages were 49.89±14.40 years in Group 1 and 48.92±14.60 in Group 2 (p = 0.704). No statistically significant differences were observed between the groups in terms of sex, body mass index, or comorbidity. However, significant differences were determined in terms of passage of kidney stones and numbers of surgical procedures performed (p = 0.001 and p <0.001, respectively). The groups’ NLR values were 2.62 (0.75-9.18) and 2.29 (0.80-6.67), and their PLR values were 136.57 (55.02-475.45) and 118.66 (37.50-244.17), respectively. The differences between the groups were not statistically significant (p = 0.139 and p = 0.076, respectively).
Conclusion: Although NLR and PLR values were higher in the group with ureteral stricture in this study, that elevation was not statistically significant. The results show that the evaluation of NLR and PLR values are not useful in predicting ureteral stricture in patients who have previously undergone endoscopic upper urinary tract surgery.
