title: Asphyxiated bladder syndrome in a pediatric intensive care unit.
abstract: Sixteen neonates and infants with asphyxiated bladder syndrome (ABS) were prospectively studied over a two-year period. Their transient urinary bladder distention had developed as a sequel of asphyxial events, and presented as delayed micturition in the absence of obstructive lesion. The incidence was 1.9 percent in this Pediatric Intensive Care Unit. Five cases occurred in the neonatal period. All patients were younger than three years of age (mean: 9.1 months), and the incidence of ABS was 2.8 percent within this age group. For intermittent decompression of the bladder, all responded successfully to the suprapubic bladder expression method (Crede's maneuver). Most (81.3%, 13/16) ABS cases coexisted with intestinal dysfunction as either paralytic ileus (62.5%, 10/16) or as gas-less abdomen (18.8%, 3/16). There was no evidence of association with either systemic or urinary bacterial infection. Normal spontaneous voiding and bowel function were regained in all cases except one, who died early. Mean (SD) duration of bladder dysfunction was 66.9 (40.3) hours. Sonography showed normal kidneys and collecting system in all patients both during and after ABS episodes. Half of the patients (8/16) died ultimately. No urinary tract abnormality was found in post-mortem examinations in five cases.
