Ultrasound guided nephrostomy in children with hydronephrosis

This study was carried out with the aim of diagnosis and percutaneous ultrasound guided nephrostomy until the condition of the child is improved for final surgical management. Nineteen children with hydronephrosis were studied. All patients were examined physically, clinically, and laboratory investigations were done. Plain radiograph of the abdomen and urinary tract intravenous pyelography, prior to ultrasound and percutaneous guided ultrasound draining of hydronephrosis and pyonephrosis by nephrostomy were done. All cases with ectopic or any congenital, mobile kidneys and renal failure were excluded from this study. The success rate was 95.4%. 19 children with hydronephrosis on their ultrasound examinations were subjected to percutaneous nephrostomy, 60% of causes of the hydronephrosis were post inflammatory. Minor problems were encountered because the technique is relatively recent and has not been utilized in Egypt, so far it is explained in details, its values and significance as well as the positive predictive value are discussed. No major complications were met, percutaneous nephrostomy drainage should be attempted as first choice of treatment of all cases with hydronephrosis and drained

Evaluation of C.T. guided biopsy in neoplastic diseases of PNS

This study included 20 cases [14 females and six males] with paranasal masses lesions suspected to be malignancy. The value of CT guided biopsy was studied for an accurate diagnosis of PNS to differentiate neoplasm mass lesions from chronic granulomatous lesions, then sensitivity and specificity of clinical CT diagnosis were compared with the results of histopathology. The patients were classified into two groups: Group A, eight patients with suspected malignant masses and Group B, 12 patients with uncertain clinical diagnosis. In group A, four cases had cancer maxillary antra, two had fungus infection, one had TB granuloma and one had non specific granuloma; while in group B, eight cases had inflammatory polyps, two had maxillary cysts, one had plasma cytoma and one had lymphoma. The successful rate was 85% [the biopsy was taken twice in two cases and failed in one due to an excess mucopurulent discharge]
