title: Genitourinary tuberculosis.
abstract: The worldwide prevalence of tuberculosis is still high and has remained almost unchanged over the past century as a result of increasing incidence in countries of the Third World. Twenty per cent of patients with tuberculosis will develop an extrapulmonary manifestation over time, the most common site being the genitourinary tract. The patient's history can lead to the sometimes difficult diagnosis. Radiological imaging helps in depicting genitourinary tuberculosis. However, the diagnosis of genitourinary tuberculosis is made on the basis of culture studies and is supported by polymerase chain reaction. The latter has impressive sensitivity and specificity, but lacks the ability to determine biological activity. The combination of three or four anti-tuberculosis drugs over a course of 6 to 9 months remains the treatment of choice. Drug resistance is increasing and necessitates tight therapy control. Tuberculosis of the male seminal duct may be an important cause of male infertility as a result of multiple epididymidal scarring. In these cases testicular sperm extraction is the method of choice for sperm retrieval. The outcome of sperm retrieval followed by intracytoplasmatic sperm injection is not affected.
