Congenital anterior urethrocutaneous fistula and megalourethra are both rare anomalies. These anomalies are commonly associated with other anorectal or genitourinary anomalies and evaluated with voiding cystourethrography. We examined a 34-month-old boy who presented with a fistula at the penoscrotal junction. A voiding cystourethrogram showed a jet of urine coming through the fistula and proximal saccular dilatation of the penile urethra. We present the imaging findings of the first case of an association between a congenital anterior urethrocutaneous fistula at the penoscrotal junction and a proximal penile megalourethra. We also discuss the etiology, management, and differential diagnosis of this entity, and review the literature.

Abstract. The development of integrating several wireless network technology make wireless network devices built everywhere. In 1999, IEEE proposes WiMAX broadband wireless technology which has high transmission bandwidth and wide coverage. There are more and more researches as abovementioned wireless technology to increase Mesh network technology which can easily increase network coverage. Intel[1] point out that integrated WiMAX/ Wi-Fi Mesh network is the best solution currently. The SS of WiMAX will the bottleneck of network traffic in WiMAX/ Wi-Fi Mesh hierarchy architecture, thus we need to manage the bandwidth between WiMAX and Wi-Fi, and support Mesh network topology development.
