Our placebo controlled, prospective, randomized study indicated that 10 cc local anesthetic injections supply significantly better pain control than lower doses for periprostatic nerve blockade during prostate biopsy. Although bilateral basal plus apical 10 cc lidocaine injections resulted in the lowest mean pain score, there was no statistically significant difference from 10 cc bilateral basal injections.

Objectives: Subclinical prostatitis is a very frequent histologic finding in pathological examinations of prostate biopsy and prostate surgery material. In this study, we tried to investigate the correlation between the morphological parameters of histological prostatitis and total serum prostate-specific antigen (PSA)-PSA density (PSAD) to determine if either the extent or aggressiveness of inflammation might affect serum PSA. Methods: 269 patients who had undergone TURP or transvesical prostatectomy with pathological diagnosis of BPH and prostatitis were included in the study. We retrospectively reviewed and scored the extent and aggressiveness of inflammation in prostate specimens of BPH, according to the scale that has been reported by Irani et al. and then correlated those scores with PSA and PSAD. Results: When the inflammation grades correlated with PSA and PSAD, the extent of the inflammation did not show a significant correlation with total PSA and PSAD (p > 0.05). However, there was a statistically significant correlation between aggressiveness grades and total PSA and PSAD (p < 0.001). Median PSA levels in grades 0, 1 and 2 of aggressiveness of inflammation were 3.2, 4.2 and 5.8 respectively. Conclusion: Aggressiveness grade of the inflammation in subclinical prostatitis is the most important morphological factor that is responsible for PSA elevation. We believe that it should be a more accurate guide for the clinician if pathologists report on the aggressiveness grades of the inflammation, especially on initial prostate biopsies, in order to help for timing of the further biopsy.

Near infrared spectroscopy is as effective but quicker than Doppler ultrasound for detecting testicular torsion without a radiologist. Near infrared spectroscopy accurately reveals oxygen saturation, which is more vital than blood flow, on which Doppler ultrasound focuses.

Introduction Achieving stone free status (SFS) is the goal of stone surgery. In this study it is aimed to compare effectiveness of unenhanced helical computerized tomography (UHCT), KUB and ultrasonography (US) for detection of residual RFs and predicition of stone releated events following percutaneous nephrolitotomy (PNL).Materials and Methods Patients underwent PNL for radiopaque stones between November 2007 and February 2010 were followed. Patients were examined within 24-48 hours after the procedure by KUB, US and UHCT. For stone size 4 mm was accepted as cut off level of significance.Sensitivity and specificity of KUB and US for detection of RFs and value of them for prediction of stone related events were calculated.Results SFS was achieved in 95 patients (54.9%) and when cut off value of 4 mm for RFs was employed, SFS was achieved in 131 patients (75.7%). Sensitivity was 70.5% for KUB, and 52.5% for US. UHCT was shown to be significantly more efficient for detection of RFs compared to both KUB (p=0.01) and US (p=0.001). When cut off level of 4 mm employed, sensitivity of KUB and US increased to 85.7% and 57.1%. Statistical significant superiority of UHCT still remained (p value vs. KUB: 0.03 and p value vs. US: 0.008).Conclusion UHCT is the most sensitive diagnostic tool for detecting RFs after PNL. It has higher sensitivity regardless of stone size compared to KUB and US. Additionally UHCT has higher capability of predicting occurrence of stone related events.
