| pubmed-article:2498991 | pubmed:abstractText | This is a report on the follow-up data of 18 patients with posterior urethral valves diagnosed during the first year of life. One infant died of progressive renal failure; a slight elevation of serum creatinine levels in three children aged 4-6 years indicated a doubtful prognosis. On initial examination, ten patients showed severe unilateral or bilateral reflux. Seven of 14 refluxing units remained non-functioning and had to be removed. Following transurethral fulguration of the valves, five infants developed unilateral or bilateral reflux which was not evident on initial preoperative voiding cystograms. In contrast to those in other series, none of these refluxes ceased spontaneously. Ureteral reimplantations were done on 11 ureters of eight patients, but regression of ureteral dilatation postoperatively remained unsatisfactory in six instances, none of whom had a true mechanical obstruction. We conclude that many of these megaloureters encountered in infants with posterior urethral valves are concomitant with profound and often irreversible damage of the ureter wall. Surgery of such ureters, therefore, should be avoided whenever feasible. | lld:pubmed |
