| Renal dysplasia is a congenital anomaly with abnormal development of nephronic and ductal structure anduntreatable disease with absent renal function. To determine whether any consistent sonographic patterns exists,the sonograms of 27 pediatric patients with maticystic dysplastic kidney were reviewed. The diagnosis was provedby pathology in 16 cases and other radiologic imaging in 11 cases. In the classical multicystic dysplastic kidney(pelvoinfundibular atresia type, 10 cases), there were typical findings, such as absent communication betweenperipherally located variable sized cysts and presence of the largest cyst away from the renal hilum. One case wasassociated contralateral renal hydronephrosis. There cases were hydronephrotic type which had medial location ofthe largest cyst with noncommunicating peripheral cysts. Segmental dysplasia with double collecting system andureterocele (5 cases) and dysplasia due to posteiror urethral valve (2 cases) showed hydronephrosis withoutidentifiable peripheral cysts. Among the hypoplastic dysplastic kidney (7 cases) including ectopic kidneys (3cases), corticomedullary differentiation were hard to be identified in 2 cases. In conclusion, diagnosis of therenal dysplasia can be obtained by US only or US with other functional studies such as radionuclide scan(99mTc-DMSA or renogram) and IVP. US detection of renal dysplasia is easy, and US findings provide valuableinformations in the subsequent management. |
