Therapeutic approaches to postoperative contracture of the vesical neck

Postoperative contracture is a rare cause of the secondary obstructions of the vesical neck, besides remnants of prostatic adenomas, recurrent adenoma and prostatic cancer. It appears morphologically either as circumscribed sclerosis, as so-called sphincter sclerosis, or as extensive contracture of the entire prostatic urethra. Severe postoperative contracture with an iris-shaped membrane at the site of the internal sphincter is the most frequent form up to one year after primary surgery. The overall incidence has been given as 1.37%, of which 13.6% were refractory to therapy and recurred. Special forms of therapy are discussed.
