Pericatheter urethrography and its use in post interlocking sound urethroplasty]

21 cases of posterior urethral rupture due to pelvic fracture were treated by acute interlocking sound urethroplasty since 1982. Postoperative pericatheter urethrography was carried out to observe the recover of urethral rupture. The results showed that the time for recover of ruptured urethra varied from 4 to 13 weeks. 71% of all cases required more than 8 weeks for recovery. The patients were followed up from 1 to 9 years, and 86% of them showed satisfactory results. It is believed that pericatheter urethrography not only provides an objective proof for the recovery of ruptured urethra but also can be used as a reliable basis for the removal of stenting catheter.
