Pelvi-ureteric junction obstruction in children.

Hydronephrosis secondary to pelvi-ureteric obstruction affecting one hundred children and derived from a 13 year period were reviewed. Particular attention was paid to symptomatology in infancy and childhood, pre-operative investigations and postoperative assessment. Following pyeloplasty the late results assessed clinically, radiologically and renographically were entirely satisfactory. The operative technique varied satisfactory. The operative technique varied according to the nature and severity of the abnormality but dismembered pyeloplasty and nephrostomy and splintage was favoured. Twelve patients with aberrant lower pole vessels had simple hitching of vessels alone with good results. Our experience suggests that the recuperative power of the kidney in the infant is unpredictable and surprising. For this reason a plea is made for extreme conservatism.
