AIM: Our aim is to introduce the cavernous artery ondulation index (CA-OI) as a new parameter that could be accepted as an indirect indicator of vascular hemodynamics and also gives us information about the efficiency of erection. PATIENTS AND METHODS: A total of 27 patients with erectile dysfunction were evaluated with penile Doppler ultrasonography (PDUS). After injection of papaverine intracavernously, arterial diameter and peak-systolic and end-diastolic velocities were measured. For measuring at a standart time, five minutes after injection, bilateral cavernosal arteries were examined and gray scale and color Doppler US images through the long axis were recorded at the mentioned phases. Cavernosal artery ondulation index (CA-OI) showing the amount of ondulation was calculated for each subject using these images. RESULTS: In 9 of total 27 patients, erection could not pass the tumescence phase with 3 flaccid phases, while the remaining 18 had full erection. Mean CA-OI values were measured as 2.51±0.37 mm, 3.15±0.38 mm, and 2.68±0.09 mm in normal, arterial insufficiency and venous insufficiency groups, respectively. CONCLUSIONS: It is possible to differentiate the arterial insufficiency by using the cut-off value of CA-OI ≥ 2.5 values as a criteria. [ABSTRACT FROM AUTHOR]

Purpose: To evaluate the effect of alpha-blocker treatment prior to transrectal ultrasound-guided prostate biopsy (TRUS-Bx) on voiding functions, pain scores and health-related quality-of-life outcomes., Materials and Methods: From January 2018 to April 2019, a total of 112 patients underwent TRUS-Bx due to elevated prostate-specific antigen (PSA) or abnormal digital rectal examination findings. Patients were divided into 2 groups depending on whether they received pharmacological treatment before biopsy. Group 1 consisted of patients with no alpha-blocker treatment prior to biopsy and Group 2 consisted of patients who received Tamsulosin for one week before biopsy continuing for one week after biopsy. Voiding function was evaluated three times using the validated International Prostate Symptom Score (IPSS) and uroflowmetry (maximal flow rate (Qmax) and residual volume (PVR)). The Turkish version of the Medical Outcomes Study Short Form 36-item Questionnaire (SF-36) was used to assess health-related quality of life. Pain scores were rated according to the Visual Analogue Scale (VAS) just after the biopsy procedure., Results: Mean IPSS and Qmax on the post-biopsy 7 day were significantly in favor of Group 2 (P<0.001, P=0.004). Although post-biopsy day 7 PVR was similar between the groups, Δ1 PVR was significantly in favor of Group 2 (P=0.004). Mean VAS score was 2.7±2.3 for the Tamsulosin group and 4.2±2.2 for the control group (P=0.001). There was no significant difference between two groups according to baseline and postoperative 1 st month SF-36 scores., Conclusion: Alpha-blocker therapy prior to TRUS-Bx is effective in preventing voiding dysfunction and biopsy-related pain in patients undergoing TRUS-Bx., Level of Evidence: 2., (Copyright © 2020 Elsevier Masson SAS.
