[Recurrent urethral strictures in men. Modern diagnosis and therapy using ultrasound and laser]

The new method of urethral sonography allows visualization of urethral strictures preoperatively in more detail than conventional X-ray urethrogram. Poor results of urethrotomies can thus be avoided in patients who have peristrictural scars. These patients can be treated by the newly developed technique of laser incisions of urethral strictures. The success rate is so promising that wall-stent implantations and even open procedures may well become very rare. Diagnostic and therapeutic techniques are discussed and described in detail with reference to illustrations.
