This study was designed to evaluate the sympathetic skin response (SSR) in men with CP type IIIb compared to normal population.Patients and Methods: For two years, about 14 patients suffering from CP type IIIb according to NIH-CPSI and 26 healthy control men were enrolled in this study. SSR was performed in all the subjects with a standard method. Bilateral palmar and plantar latency and amplitude of SSR were recorded in response to the median and tibial nerve electrical stimulations. SSR is considered abnormal when the latency is prolonged, and the amplitude reduced.Results: SSR latency in the left and right median nerve was significantly prolonged in the patient with CP type IIIb group compared to the control group (p=0.039 and 0.006, respectively). Additionally, the amplitude was reduced in patients with CP type IIIb group compared to the control group in the right tibial nerve (p=0.017).Conclusion: Sympathetic skin response may be a helpful diagnostic test for men with chronic prostatitis type IIIb. However, this observation needs to be validated in a large sample cohort study with long-term follow-up.Keywords: chronic prostatitis, prostate, sympathetic skin response

Patients and methods: A total of 184 patients suspected with urolithiasis who had undergone NCCT and US radiologic investigation from 2015 to 2017 were enrolled in this study. The sensitivity, specificity, and stone size measured in US were validated by NCCT. Data of the stone size in US were classified into four groups (0–3.5, 3.6–5, 5.1–10, >10 mm) and then compared with NCCT data. Results: In 184 patients, NCCT detected 276 (97.2%) stones, while US could identify 213 (75.5%) stones. Overall sensitivity and specificity of US were 75.4% and 16.7%, respectively. Detection rate of mid and distal ureteral stone was lower than that at other locations. The detection rate increased with the stone size. About 73% concordance was obtained for the stone size measured by US and NCCT (Pearson’s correlation coefficient was 0.841). Factors such as the stone size, amount of hydronephrosis, and weight affected the detection rate of the urinary tract stone using US (P
