Ejaculatory duct obstruction is an infrequent cause of obstructive azoospermia, occurring in up to 5 % of such patients. However, it is potentially correctable and warrants consideration in the differential diagnosis of the patient presenting for infertility evaluation. This review provides an overview of ejaculatory duct obstruction: its various etiologies, presentation, and associated clinical assessment. It includes a description of diagnostic imaging and interventional studies available to the practicing urologist and concludes with a discussion of current endoscopic management.

Interference with the secretion of tears by the lacrimal glands. Obstruction of the lacrimal sac or nasolacrimal duct causing acute or chronic inflammation of the lacrimal sac (DACRYOCYSTITIS). It is caused also in infants by failure of the nasolacrimal duct to open into the inferior meatus and occurs about the third week of life. In adults occlusion may occur spontaneously or after injury or nasal disease. (Newell, Ophthalmology: Principles and Concepts, 7th ed, p250)
Application of electric current in treatment without the generation of perceptible heat. It includes electric stimulation of nerves or muscles, passage of current into the body, or use of interrupted current of low intensity to raise the threshold of the skin to pain.
Removal of tissue with electrical current delivered via electrodes positioned at the distal end of a catheter. Energy sources are commonly direct current (DC-shock) or alternating current at radiofrequencies (usually 750 kHz). The technique is used most often to ablate the AV junction and/or accessory pathways in order to interrupt AV conduction and produce AV block in the treatment of various tachyarrhythmias.
