    Extracorporeal Shock Wave Lithotripsy (SWL) has long been used successfully to dissolve ureteral stones. We researched whether Hounsfield values of ureteral stones is a factor that affects the success of SWL. Methods: Data from 144 patients who had diagnoses of ureteral stones and underwent SWL, were retrospectively reviewed between January 2011 and December 2012. Urinary tomography of patients was processed and classified into 3 groups by Hounsfield units (Group 1, < 500 HU; Group 2, 500-1000 HU; and Group 3, > 1000 HU) and 2 groups by stone size (Group A; < 1 cm, Group B; > 1 cm). SWL success was analyzed for both of these group types. Failure was defined as any fragments of the stone that remained within the ureter. Results were analyzed by evaluating the predictive factors in both groups. Results: The study included 144 patients (100 men, 44 women) who fit the inclusion criteria. In Hounsfield unit Group 1 (12 women and 44 men), the mean age was 37.2 +/- 13.2, stone size was 8.5 +/- 2.5 mm, number of shocks was 3240 +/- 1414 (1200-7500) and number of treatments was 1.4 +/- 0.6. In Group 2 (26 women and 32 men), the mean age was 33.6 +/- 7.6, stone size was 9.6 +/- 3.1 mm, process number was 3375 +/- 2103 (1200-8750) and shock amount was 1.6 +/- 0.8. In Group 3 (6 women and 24 men), the mean age was 42.2 +/- 13.6, stone size was 11.7 +/- 3.0 mm, number of shocks was 4513 +/- 2458 (1300-8700) and number of treatments was 2.1 +/- 1.2. In size Group 1 (28 women and 74 men), the mean age was 35.8 +/- 10.6, stone size was 8.1 +/- 1.4 mm, process number was 3105 +/- 1604, shock amount was 1.4 +/- 0.5 and HU value was 580 +/- 297. In Group 2 (16 women and 26 men), the mean age was 39.9 +/- 14.2, stone size was 13.9 +/- 2.4 mm, number of shocks was 4722 +/- 2467, number of treatments was 2.3 +/- 1.1 and HU value was 912 +/- 270. Conclusion: Although stone density predicted the failure of SWL, size of the stone is more important criterion for successful lithotripsy of ureteral stones.

    Benign Prostat büyümesi olan hastalarda infravezikal obstrüksiyon en iyi göstergesi nedir?
    (2012) Sinanoğlu, Orhun; Hazar, A. İsmet; Balcı, Mustafa Bahadir Can; Aksoy, S. Hilmi; Çakıroğlu, Basri; Nuhoğlu, Barış
    Amaç: Bu çalışmanın amacı, benign prostat hiperplazisi (BPH) olan hastalarda infravezikal obstrüksiyon derecesini tahmin etmekte kulanılan uluslararası prostat semptom skoru (IPSS) ile üroflovmetri, prostat volümü ve postmiksiyonel rezidüel idrar (PVR) miktarı arasındaki korelasyonu değerlendirmektir. Yöntemler: Üroloji polikliniğine Ocak 2010 ile Aralık 2010 tarihleri arasında başvuran işeme şikayeti ile muayene edilen 134 hasta retrospektif olarak incelendi. Hastalar IPSS değerlerine göre üç gruba ayrıldı; 1. Grup IPSSi hafif olan hastalar (n=35 hasta), 2. Grup IPSSi orta olan hastalar (n=67) ve 3. Grup IPSSi olan hastalar (n=32). Hastaların IPSS ile prostat volümü, PVR ve üroflovmetri bulguları arasındaki ilişki karşılaştırıldı. Prostat hacimleri ile PVR suprapubik ultrasonografi ile değerlendirildi. İşemeyi etkileyebilecek üriner sistem rahatsızlıkları olan hastalar çalışmaya dahil edilmedi. Bulgular: Çalışmaya dahil edilen hastaların ortalama yaşı 55.6 (43-88) iken tüm grubun ortalama IPSSsi 13.5 (0-35) idi. Üçüncü gruptaki prostat hacimleri ve rezidüel idrar miktarları 1. Gruba ve 2. Gruba göre istatistiksel olarak anlamlı derecede daha fazla idi. Ortalama mesane duvar kalınlığı 2. Grup ve 3. Grup ile karşılaştırıldığında,1. Grupta anlamlı derecede daha düşük idi. Sonuç: Benign prostat hiperplazisi hastalarında IPSS öznel bir bulgu olsa da, alt üriner sistem yakınmaları daha yüksek olan hastalarda, nesnel olan üroflovmetri ve ultrasonografik parametrelerde de eşdeğer bir bozulma görülmektedir.

    Infravesical Obstruction Index in Patients with Benign Prostatic Hyperplasia is the Best?
    (Aves, 2012) Çakıroğlu, Basri; Sinanoğlu, Orhun; Hazar, A. Ismet; Balci, M. B. Can; Nuhoğlu, Baris; Aksoy, S. Hilmi
    Objective: The aim of the study is to evaluate the correlation among the factors such as the International prostate symptom score (IPSS), uroflowmetry (Qmax), prostate volume and postvoiding residue (PVR) in predicting infravesical obstruction in patients with benign prostate hyperplasia. Methods: The data of 134 patients referred to the urology outpatient clinic between January 2010 and December 2010 were retrospectively reviewed. The patients were distributed in three groups according to IPSS values; 1st, lower IPSS group (n=35), 2nd, moderate IPSS group (n=67) and 3rd, higher IPSS group (n=32). IPSS, prostate volume, postvoiding residue (PVR), and maximum urine flow (Qmax) values were compared. Prostate volumes and PVR were evaluated with suprapubic ultrasound. The patients with comorbidities which may affect voiding function were excluded from the study. Results: The mean age and IPSS of study patients were 55.6 (43-88) and 13.5 (0-35) respectively. Mean prostate volume and PVR of the 3rd group were significantly higher compared to the 1st and 2nd groups. Conclusion: Although IPSS is a subjective finding of infravesical obstruction, a higher score in patients with lower urinary tract symptoms is in parallel with the objective parameters such as Qmax and PVR.
