ABSTRACT
Objective: The Visual Prostate Symptom Score (VPSS) is a simple tool developed to evaluate lower urinary tract symptoms (LUTS), particularly in individuals with low educational levels. This study investigated the relationship between the urinary stream image in the first question of the VPSS and the maximum urinary flow rate (Qmax). The aim was to estimate Qmax in patients unable to undergo testing and to reduce unnecessary uroflowmetry procedures. Material and Methods: A total of 93 patients over the age of 40 who had completed the VPSS form and undergone at least two uroflowmetry tests were included. Patients with diabetes, neurological diseases, a history of prostate or urethral surgery, and those with a voided urine volume of less than 150 mL were excluded. Based on the image in the first VPSS question, patients were divided into five groups. The relationship between this image and Qmax was analyzed using Pearson correlation. Variables such as age, voided volume, and presence of a median lobe were evaluated using multivariate regression analysis. Results: A strong negative correlation was found between the first VPSS question and Qmax (r=-0.942, p<0.001). While Qmax was within normal limits in the first two groups (24.33 mL/s and 16.21 mL/s), it was lower in the fourth and fifth groups (7.26 mL/s and 5.22 mL/s). The third group fell within a gray zone (11.11 mL/s). Conclusion: The urinary stream image in the VPSS shows a significant correlation with Qmax and may serve as a practical evaluation tool, especially in patients who are unable to undergo uroflowmetry.

ÖZET
Amaç: Görsel Prostat Semptom Skoru (GPSS), özellikle düşük eğitim düzeyine sahip bireylerde alt üriner sistem semptomlarını değerlendirmek için geliştirilmiş basit bir ölçektir. Bu çalışmada, GPSS'nin birinci sorusundaki idrar akım görseli ile maksimum idrar akış hızı (Qmax) arasındaki ilişki araştırılmıştır. Amaç, test yapılamayan hastalarda Qmax hakkında öngörü sağlamak ve gereksiz üroflowmetri testlerini azaltmaktır. Gereç ve Yöntemler: VPSS formunu doldurmuş ve en az iki kez üroflowmetri uygulanmış, 40 yaş üzeri 93 hasta incelendi. Diyabet, nörolojik hastalık, prostat/üretra cerrahisi öyküsü olanlar ve idrar hacmi <150 mL olanlar dışlandı. VPSS'nin birinci sorusundaki görsele göre hastalar 5 gruba ayrıldı ve görsel ile Qmax arasındaki ilişki Pearson korelasyon analizi ile değerlendirildi. Yaş, işeme hacmi ve median lob varlığı gibi değişkenler çok değişkenli regresyon ile analiz edildi. Bulgular: VPSS'nin birinci sorusu ile Qmax arasında güçlü bir negatif korelasyon saptandı (r=-0,942, p<0,001). İlk iki grupta Qmax normal düzeyde iken (24,33 mL/sn ve 16,21 mL/sn), dördüncü ve beşinci gruplarda düşüktü (7,26 mL/sn ve 5,22 mL/sn). Üçüncü grup gri bölgede yer almaktaydı (11,11 mL/sn). Sonuç: GPSS'nin idrar akış görseli, Qmax ile anlamlı ilişki göstermekte olup, özellikle üroflowmetri yapılamayan hastalarda pratik bir değerlendirme aracı olarak kullanılabilir.
