Scrotal calculi in clinical practice and their role in scrotal pain: A prospective study.

PURPOSE: Scrotal calculi are rare, and their clinical significance is uncertain. Scrotal pain is a frequent, hard-to-manage problem in urology clinics. Our purpose in this study was to determine the relationship between the presence of scrotal calculi and scrotal pain in a prospective manner. METHODS: Sonography and color Doppler ultrasound of the scrotum were performed in 758 consecutive patients referred with scrotal pain. The pain was rated by using an 11-point numeric rating scale; scores were compared among patients with scrotal calculi with and without additional scrotal pathology. RESULTS: Scrotal calculi were detected in 73 of the 758 patients (9.6%). Scrotal pain (n = 50 [61%]) and a palpable mass in the scrotum (n = 25 [30.5%]) were the most common complaints in patients with scrotal calculi. Hydrocele (n = 17 [29.8%]) and varicocele (n = 15 [26.3%]) were the most commonly associated abnormalities; there was a statistically significant association between the presence of scrotal calculi and hydrocele (p < 0.01). Scrotal pain was present in 61 (83.5%) patients with scrotal calculi, and this association was significant (p < 0.001). The presence of scrotal pain and the correlation between location of calculi and pain in patients without additional scrotal abnormalities were also significant (p = 0.04 and p < 0.004, respectively). CONCLUSIONS: The prevalence of scrotal calculi was 9.6%, and hydrocele was found to be associated with scrotal calculi. We also found a significant relationship between the presence of calculi and scrotal pain. Because the etiology of scrotal pain is essential for appropriate treatment, scrotal calculi should be kept in mind when making a differential diagnosis of scrotal pain. © 2014 Wiley Periodicals, Inc.

The use of real-time elastography in the assessment of gallbladder polyps: preliminary observations.

AIMS: Gallbladder polyps often have a benign nature. Current guidelines suggest surgical removal of polyps greater than 10 mm. However, the accuracy of the size criteria is limited because neoplasia can be found in gallbladder polyps less than 10 mm. The aim of this study was to evaluate the feasibility of real time elastography for gallbladder polyps and to demonstrate the elasticity properties of the polyps. MATERIAL AND METHOD: Fifty-three polypoid lesions of the gallbladder were prospectively examined with real-time elastography. Of these patients, 52 had a diagnosis of benign gallbladder polyps and one patient was accepted as a gallbladder carcinoma due to its clinical and radiological findings. B-mode and real-time elastographic images were simultaneously presented as a two-panel image, and the elastogram was displayed in a color scale that ranged from red (greatest strain, softest component), to green (average strain, intermediate component), to blue (no strain, hardest component). RESULTS: The mean size for benign gallbladder polyps was 7.2 +/- 3 mm (range, 5-21 mm). All benign gallbladder polyps on consecutive real-time elastographic images appeared as having a high-strain elastographic pattern. Only one patient who was accepted with gallbladder carcinoma had a gallbladder polyp with low elasticity properties. CONCLUSIONS: Our study showed that real time elastography of gallbladder polyps is feasible. This novel approach may be useful for the characterization of polypoid lesions of the gallbladder.
