Effect of Doxazosin on Prostatic Resistive Index in Patients with Benign Prostate Hyperplasia

Abstract

Objective: In recent years several studies revealed that prostatic resistive index (RI) was increased on power Doppler imaging (PDI) in patients with benign prostate hyperplasia (BPH). In the present study we aimed to evaluate the effect of Doxazosin on prostatic RI in BPH patients. Materials and Methods: Forty BPH patients with lower urinary tract symptoms included in this study. All patients received 8mg Doxazosin daily for six months. International prostatic symptom scores (IPSS), maximal urine flow rates (Qmax), total prostate volumes and prostatic RI determination with PDI were compared before and after the treatment. Results: The mean age, IPSS and Qmax of the patients was 60.2±2 years, 20.3±4.5 and 11.3±3.0 mL/s respectively. There was a positive correlation between prostatic RI, total prostate volume and IPSS before the treatment (r=0.37 p=0.02 and r=0.40 p=0.017, respectively). On the other hand there was a negative correlation between prostatic RI and Qmax values (r= -0.38 p=0.021). There was a significant improvement in IPSS scores and Qmax values after the treatment (7.9±5.3 and 16.8±5.8 mL/s respectively, p

Benign Prostat Hiperplazili Hastalarda Doksazosinin Prostatik Rezistif İndeks Üzerine Etkisi

Öz

Amaç: Son yıllarda yapılan birkaç çalışmada benign prostat hiperplazili (BPH) hastaların power doppler ultrasonografi (USG) ile tespit edilen prostatik rezistif indekslerinde artış tespit edilmiştir. Bu çalışmada BPH’lı hastalarda doksazosin tedavisinin prostatik rezistif indeks üzerine etkisi değerlendirildi. Gereç ve Yöntemler: Çalışmaya alt üriner sistem semptomları nedeniyle BPH düşünülen 40 hasta alındı. Tüm hastalara 6 ay boyunca günde 8 mg doksazosin tedavisi verildi. Tedavi öncesi ve sonrası hastaların uluslararası semptom skorları (IPSS), maksimal akım hızları (Qmax), total prostat volümleri (TPV) ve power doppler USG ile tespit edilen prostatik rezistif indeksleri karşılaştırıldı. Bulgular: Hastaların ortalama yaşı 60.2±2 yıl, IPSS 20.3±4.5 ve Qmax 11.3 ±3.0 m/sn idi. Tedavi öncesi hastaların prostatik rezistive indeksi ile TPV ve IPSS arasında pozitif (sırasıyla, r=0.37 p=0.02 ve r=0.40 p=0.017), Qmax arasında negatif korelasyon tespit edildi (r=-0.38 p=0.021).Tedavi sonrası hastaların IPSS ve Qmax değerlerinde anlamlı derecede iyileşme mevcuttu (sırasıyla,7.9±5.3 ve 16.8±5.8, p
