The operative management of posterior urethral valves.
The surgical management of posterior urethral valves remains controversial. To examine the effects and results of operative treatment in boys with proven posterior urethral valves, a retrospective study was undertaken. The case records of 33 male children who presented with posterior urethral valves over a 10-year period were reviewed. Two patients died prior to definitive treatment and one died postoperatively. Following resuscitation and diagnostic procedures, the remaining patients had eradication of the posterior urethral valves by electrothermic fulguration. In 14 patients this was performed using the Innes-Williams diathermy hook under control of contrast enhanced radiography. In 16 patients the valves were fulgurated under direct cystoscopic visualization. All surviving patients had an uneventful postoperative recovery. However, of those undergoing cystoscopic fulguration, four developed symptomatic urethral strictures necessitating repeat cystoscopy and urethral dilatation. No cases developed strictures following the use of the diathermy hook. One patient from each treatment group developed dribbling. The Innes-Williams diathermy hook has been proven to be a safe, simple, and inexpensive technique. This has specific application in the neonate and small infant where cystoscopy poses technical problems because of anatomic size and where potentially traumatic urethral instrumentation should be avoided.
