Needle biopsy in the diagnosis of testicular leukemia in children.

Aggressive chemotherapy in patients with acute lymphoblastic leukemia has resulted in a marked upsurge in patient survival. In the course of their management, testicular biopsy and rebiopsy have an important role. We evaluated the histological findings in 50 sets of open wedge and simultaneous needle core biopsy specimens from 44 testes of children with acute lymphoblastic leukemia to determine the accuracy of the needle biopsy technique in the evaluation of testis involvement in acute lymphoblastic leukemia. We conclude that needle biopsy of the testis in acute lymphoblastic leukemia is highly accurate and correlates well with the conventional open wedge biopsy, and it may have a role in the management of children with acute lymphoblastic leukemia.

Fibroepithelial polyp in a child.

Only 15 cases of fibroepithelial polyp in children have been reported in the world medical literature. Clinical differentiation between this tumor and a malignant ureteral tumor is difficult and often results in unnecessary nephrectomy. We report the sixteenth case of a child with fibroepithelial polyp of the ureter. The lesion was resected, and the kidney was preserved. Optimum treatment of this lesion mandates renal preservation in children. The rationale for this recommendation is explored.

The dilated urinary tract in children. Prospective analysis with correlation of radiological, isotope, pressure perfusion and surgical findings.

Moderate and even severe dilatation of the urinary tract in the absence of vesicoureteric reflux may remain stable or show spontaneous resolution. Two such cases are described. Twenty-five children with dilated urinary systems were studied to correlate the radiological, isotope, pressure perfusion and surgical findings. A positive Whitaker test correlated well with the surgical findings and post-operative improvement in renal function in all patients with pelviureteric junction (PUJ) and vesicoureteric junction (VUJ) obstruction. High flow rates of 8.6 and 12 ml are required even in neonates and infants in order to demonstrate obstruction by Whitaker testing.

Xanthogranulomatous pyelonephritis in children.

We report on a child with xanthogranulomatous pyelonephritis--an uncommon entity in children. A review of the literature revealed that in only 18 per cent was the diagnosis made correctly preoperatively. In children the disease is of a focal nature rather than a diffuse one, suggesting that possibly radical surgery would be less necessary for adequate treatment.

Routine intraoperative post-ligation venography in the treatment of the pediatric varicocele.

Varicocelectomy in the adult is followed by a relatively low recurrence rate but children treated by conventional techniques seem prone to have more frequent recurrences. We believe that the higher recurrence rate observed in children after routine varicocelectomy actually represents residual varicose communications that had been missed at the primary operation. Routine post-ligation intraoperative venography has been used to detect these occult communications in 26 children undergoing varicocelectomy. Our results indicate a low recurrence rate (3.6 per cent), suggesting that routine use of this procedure with childhood varicocelectomy is beneficial.

Successful treatment of renal vein and vena caval extension of nephroblastoma by preoperative chemotherapy.

Intravascular nephroblastoma involving the renal veins or inferior vena cava, occurring in 6 to 10 per cent of the cases, dramatically complicates the treatment course for those individuals. Heroic surgical procedures, including sternal splitting and cardiopulmonary bypass, have been used to treat these tumors, often with an added morbidity and increased mortality. We have detailed the dramatic responses to preoperative chemotherapy in 3 patients with intravascular nephroblastoma, which resulted in either complete eradication or marked shrinkage of the intravascular tumor, greatly simplifying the ensuing surgical procedure. These observations strongly indicate that preoperative chemotherapy should be used as the primary treatment in patients with this condition.
