title: [Pyeloplasty in infants and children].
abstract: Pyeloureteral obstructions of various pathogeneses and their complications can be visualized satisfactorily be means of intravenous urography. Of the other diagnostic methods angiography was found to be the most useful, no retrograde examination was carried out. When distension of the end of the calyx or obvious parenchymal lesion appears, plastic operation must be performed irrespective of the patient's age, the presence of infection or anomaly of the localization. Only kidneys which have lost their functions should be removed. In the operation the pyeloureteral boundary is always excised, the new transition is secured by splinting and a transrenal drain is used. Secondary nephrectomy had to be performed in a single case. One-year and three-year intravenous urographic check-ups showed in 72 of the 100 cases good, in 19 satisfactory results, in 8 cases the pyeloureteral boundary was funnel-shaped, but the dilatations of the calyx-ends remained unchanged. Pyeloplasty is no longer a high-risk operation.
