Partial nephrectomy in well-responding stage I Wilms' tumors: report of three cases.

We report on 3 of 21 stage I Wilms' tumor patients with tumor volumes of 190, 890, and 1300 mL, respectively, who responded dramatically to preoperative chemotherapy according to the Austrian/Hungarian Wilms' Tumor Study 89 by tumor volume reductions to 20%, 23%, and 13%, respectively. Radical resection of the tumors with renal preservation was achieved in all patients. Postoperative studies did not show any functional deficit in the preserved kidney. The patients have been in complete remission for 26, 33, and 60 months, respectively. Our preliminary results indicate that tumor resection should be feasible in patients with good responding stage I Wilms' tumors.

[Neonatal segmental cystic nephroma. A case report].

UNLABELLED: Multicystic segmental renal dysplasia is rare in early childhood. We report a case with prenatally recognized renal malformation. Prenatally a cystic renal malformation was detected sonographically; postnatally further evaluation was performed by Doppler sonography, contrast enhanced CT and voiding cysto-urethrography leading to the diagnosis of a multicystic segmental nephroma. Due to increasing size in spite of therapeutic and diagnostic sonographic guided punctures and the atypic manifestation the baby underwent heminephrectomy. The final histological diagnosis confirmed preoperativ findings. CONCLUSION: Prenatally recognised cystiform renal malformations should be reevaluated postpartally by ultrasound and--as doubtful findings are found--further imaging might be necessary for follow up and for the decision on conservative or operative treatment.

Continuous arteriovenous hemofiltration in infants.

Renal replacement therapy is sometimes necessary in small infants with acute renal failure or severe metabolic disorders. Of the available methods hemodialysis and peritoneal dialysis are not always feasible in small infants. We used continuous arteriovenous hemofiltration as renal replacement therapy in five small infants. This report describes the technique and efficiency of this new extracorporal treatment modality. Azotemia and hypervolemia can be controlled easily by spontaneous or suction supported arteriovenous hemofiltration. Furthermore it allows adequate parenteral nutrition in anuric infants and eliminates toxic products in amino acid disorders. Arteriovenous hemofiltration is well tolerated by small infants and can be performed in every pediatric intensive care unit.

Arteriovenous hemodiafiltration in children.

Continuous arteriovenous hemofiltration is a safe and effective renal replacement therapy system for critically ill patients. In hypercatabolic states urea elimination is too low resulting in high serum urea levels. The aim of this report is to describe the technique of arteriovenous hemodiafiltration and its efficiency on urea elimination. Using two different hemofilters urea clearances achieved by means of arteriovenous hemodiafiltration approximately doubled when compared with spontaneous arteriovenous hemofiltration (urea clearance: 1.25 +/- 0.24 ml/min.-CAVH versus 2.6 +/- 0.59 ml/min.-CAVHDF-0.1sqm hemofilter and 11.77 +/- 1.82 ml/min.-CAVH versus 21.63 +/- 2.63 ml/min.-CAVHDF-0.6sqm hemofilter). Arteriovenous hemodiafiltration is a safe and simple extracorporal technique well tolerated by children. It's a useful adjunct to spontaneous arteriovenous hemofiltration to control azotemia in critically ill hypercatabolic patients.

Acute renal failure due to atraumatic rhabdomyolysis in coma diabeticum.

A case report of a twelve year old boy with coma diabeticum and atraumatic rhabdomyolysis is presented. At admission the patient was comatose. Hyperglycemia and hyperosmolarity were the main metabolic disorders. 32 hours after admission marked myoglobinuria due to atraumatic rhabdomyolysis led to acute renal failure. At first uremia was compensated by arteriovenous hemofiltration and later by conventional hemodialysis. During the sixth week after admission urinary output started and serum creatinine and urea levels gradually declined to normal. Special attention should be paid to atraumatic rhabdomyolysis in patients with coma diabeticum. Continuous arteriovenous hemofiltration is an effective extracorporal therapeutic technique to compensate uremia in critically ill patients.

[Color Doppler ultrasound in differential diagnosis of unilateral congenital cystic kidney abnormalities].

Doppler-sonography was performed in 16 newborns with prenatally diagnosed unilateral cystic renal malformation. 11 babies with multicystic dysplastic kidneys showed doppler-sonographically reduced systolic flow velocities and elevated resistive index (RI) [RI = 90-100%] or lack of obtainable perfusion signals. 4 of them had to undergo nephrectomy, the other asymptomatic patients could be managed conservatively, spontaneous regression could be observed. 5 other infants suffering from cystic nephroma, severe ureteropelvic junction obstruction, hudge bleeding of the adrenal gland and hydronephrosis due to ectopic ureter, having been prenatally presented as "cystic renal malformations", initially showed normal systolic flow velocities within renal parenchyma and only slightly elevated RI (mean = 83%). By this they could be differentiated from multicystic kidney dysplasia. We therefore propose to use doppler-sonography for differential diagnosis of prenatally assumed cystic kidney malformations.
