Crossed fused renal ectopia is a rare congenital anomaly, and is mostly detected incidentally. A 45-year-old man, during investigation for recurrent abdominal pain, was found to have an empty left renal fossa and right crossed renal ectopia with fusion on ultrasonography. In the present case, there were no abnormalities and/or alteration of the renal function. Abdominal tomography scan with contrast medium confirmed the diagnosis. Ectopic kidney is often associated with other abnormal situations such as agenesis, vascular malformation, incontinence, a palpable abdominal mass, urinary tract infection, high incidence of stone formation, and genital anomalies. Through this case report, we emphasize the importance of adequate imaging.
A functioning vascular access is a critical requirement to improve the quality of life in hemodialysis patients, so monitoring and surveillance of vascular access play key roles in identifying all dysfunctions and reducing the huge economic cost as well as adequacy of dialysis.In our five-year experience, a study protocol has been used and improved with the help of ultrasonography.Doppler ultrasound is an excellent and sensitive modality for hemodialysis access evaluation, one of techniques employed for arteriovenous fistulae (AVF) study, not only as a preoperative tool, but also in post-operative monitoring of AVF maturation. In addition, the current guidelines recommend AVF surveillance by access blood flow measurement and the correction of hemodynamic stenosis in order to prolong access survival. Doppler ultrasound is readily available, directly used by nephrologists, non-invasive, safe, inexpensive, reproducible, although it requires more clinical skill and time to perform and proper equipment. Ultrasonography imaging can substantially reduce the number of subsequent invasive angiographic procedures. In our opinion, Doppler ultrasound should have a crucial place in the interdisciplinary cooperation in AVF monitoring and it should be included as part of an integrated vascular access management program.
Primary bladder neck obstruction (PBNO) was first described in men by Marion in 1933. The precise cause of PBNO has not been clearly elucidated. This paper review the theories on etiology, clinical presentation, diagnostic evaluation and treatments for PBNO. Also this paper focuses on management of patients with complications like acute urine retention, hydroureteronephrosis and severe renal failure. The treatment options for men and women with PBNO include careful clinical evaluation, pharmacotherapy with alpha-blockers and surgical intervention.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
