Introduction: Transition Zone Index (TZI) is a parameter for diagnosis and evaluation of symptoms in patients with Benign Prostatic Hyperplasia (BPH). The aim of this study is to evaluate the role of measuring transition zone index in patients with lower urinary tract symptoms (LUTS) and to asses the correlation between International Prostate Symptom Score (IPSS), peak urine flow (PUF), age and PSA.
Materials and Methods: The study included 81 patients with LUTS. Age, IPSS, PUF and PSA were determined in all patients and these parameters were evaluated for the correlation with TZI. Additionally, age, IPSS and PSA values were grouped and each one was statistically analyzed with TZI. Afterwards TZI was fixed and statistical analyses were carried out between the groups.
Results: The mean age of the patients was 62.6 +/- 8. There was statistically significant positive correlation between TZI values and age, IPSS score and PSA values and statistically significant negative correlation between TZI and PUF (p<0.001). Furthermore, when the patients were sub grouped according to age, PSA and IPSS scores it was noted that in the event of increase in these parameters there was also statistically significant increase in TZI.
Conclusion: In this study, strong correlation was observed between IPSS, PSA, PUF, age and TZI. This result suggests that TZI value is more useful parameter than prostate volume and TZV for evaluation of patients with BPH.
