Posterior urethral valves: varied presentations & outcome after preliminary surgical treatment.
J Surg Pak Jan ;12(2):43-6.

Objective: To find out various modes of presentation and outcome after preliminary surgical treatment of posterior urethral valves in pediatric population. Study design: Descriptive study. Place & duration of study: Surgical Unit B National Institute of Child Health, Karachi, during the years 2004-2005. Patients & Methods: All consecutive patients coming in outpatient / emergency departments, diagnosed as having posterior urethral valves and those who had received initial treatment and came for follow up, were included in the study. All the neonates underwent vesicostomy initially, followed by valve ablation at appropriate age with plan for undiversion at later date. In infants valve ablation was performed if urethral size admitted pediatric cystoscope while older children underwent primary valve ablation. Results: There were total of 22 patients managed during the study period. They included 5 neonates (0-1 month), 11 infants (1-12 months) and 6 older children (1year-12 years). The main presenting complaint in majority of neonates was inability to pass urine and one had urinary ascites. Infants presented mainly with either difficulty in passing urine (n 5) or dribbling and acute urinary retention in 2 patients` each. Majority of older children (n 3) presented with poor urinary stream and dribbling while two had diurnal enuresis and one came with straining at micturition. In all the neonates vesicostomy was performed. Out of these 3 received valve ablation therapy, followed by undiversion. Two of them improved while 1 had bladder dysfunction. Of the remaining 2 patients with vesicostomy 1 is still waiting for definitive procedure while the other is lost to follow up. Of infant group, 8 were subjected to vesicostomy and valves ablated at later stage whereas 2 received primary valve fulguration therapy. One patient of this group died before any intervention performed. In older age group, 3 received valve ablation as initial treatment while 3 were lost to follow up before any intervention. Outcome assessed clinically, biochemically and radiologically. Out of total 22, four had not received any intervention. Of the remaining 18, treatment completed in 12 patients, 8 of these improved and 4 had residual disease. Two patients expired and 4 were lost to follow up. Conclusions: The overall improvement rate observed at the end of our study was 44%. In 22% patients there were still residual ongoing problems that need to be addressed on long term basis.
