[Retroperitoneal bronchogenic cyst: a case report].

A rare case of retroperitoneal bronchogenic cyst is presented. A 50-year-old man was referred to our hospital for an investigation of a retroperitoneal mass. Computed tomography and magnetic resonance imaging confirmed a retroperitoneal mass, about 4 cm in diameter, adjacent to the left kidney and spleen. On the basis of these imaging modalities, a definitive diagnosis of this mass could not be made. So, resection of the mass was performed. The removed mass was an unilocular cyst and filled with mucinous fluid. Histopathologically, the cyst wall was composed of a fibrovascular connective tissue containing mucus-secreting glands and cartilages and was lined by ciliated pseudostratified columnar epitherium. Thus, a diagnosis of bronchogenic cyst was made. Bronchogenic cysts are rare congenital anomalies of the primitive foregut and usually develop in the mediastinum and lung.

The Association between Severity of Atherosclerosis and Lower Urinary Tract Function in Male Patients with Lower Urinary Tract Symptoms.

OBJECTIVES: The present study was undertaken to investigate the association between the severity of atherosclerosis and lower urinary tract function in male patients with lower urinary tract symptoms. METHODS: Male patients with lower urinary tract symptoms were examined with routine investigation. The severity of atherosclerosis was assessed by ultrasound examination of carotid artery. Patients were divided into two groups: control group and atherosclerosis group. The voiding function and storage function were compared between the two groups. RESULTS: A total of 50 men (69.9 ± 9.1 years [mean ± standard deviation]) entered the study. There was no significant difference in age distribution (control group: 68.7 ± 7.6 years; atherosclerosis group: 72.5 ± 9.7 years) and prostate volume (control group: 26.5 ± 17.3 mL; atherosclerosis group: 22.2 ± 11.0 mL) between the two groups. In the voiding parameters, maximum flow rate in the atherosclerosis group (13.4 ± 5.5 mL/s, P < 0.05) was significantly lower than that in the control group (16.7 ± 7.7 mL/s). Postvoid residual urine volume showed no significant difference between the two groups. In the storage parameters, voided volume was significantly reduced in the atherosclerosis group (161.8 ± 46 mL, P < 0.05), as compared to control group (201.1 ± 78 mL). Moreover, daytime frequency was 7.13 ± 3.02 times in the control group, and significantly higher in the atherosclerosis group (8.75 ± 2.50 times, P < 0.05). CONCLUSION: Development of atherosclerosis impairs both voiding and storage function independently of age, suggesting atherosclerosis leads to lower urinary dysfunction.
