[Treatment of the loss of major wall substance in children using synthetic resorbable mesh. Apropos of 10 cases].

Ten children with a major parietal defect, abdominal or thoracic, were operated by using a resorbable polyglactine network, during these three last years. On six children, the parietal defect was only deep, according to the surgical ablation of a parietal malignant tumor; on four other children, the defect was total, interesting the muscular and aponeurotic plan, but also the skin (two gastroschisis, and two septic eviscerations). Neither reject nor suppuration were observed. In case of total defect, a parietal reflection may be necessary in the long term.

[Obstructive anuria in children. Apropos of 22 cases].

The authors report twenty two cases of obstructive anuria observed in children. Causes are diverse: 6 cases were observed during the course of tumors, 4 cases were secondary to bilateral renal stones (or unilateral in a single kidney), 3 cases were observed before surgical correction of latent or well tolerated congenital uropathy, and 9 cases in the immediate postoperative period (including 8 after antireflux surgery). In the emergency situation, treatment of obstructive anuria is based on urinary diversion ideally by percutaneous nephrostomy under ultrasonic control. But prevention is the best treatment of anuria: treatment of urinary tract infections resulting in renal stones, in case of tumor, ultrasonographic survey of chronic upper tract dilatation: rigorous atraumatic operative technique avoiding any oedema.

[Obstructive anuria in children. Apropos of 22 cases].

The authors report twenty-two cases of obstructive anuria observed in children. Causes were diverse: 6 cases were observed during the course of tumors, 4 cases were secondary to bilateral renal stones (or unilateral in a single kidney), 3 cases were observed before surgical correction of latent or well tolerated congenital uropathy, and 9 cases occurred immediately after an operation (including 8 after antireflux surgery). Emergency treatment of obstructive anuria is based on urinary diversion, ideally by percutaneous nephrostomy under ultrasonic control. However, prevention is the best treatment of anuria: treatment of urinary tract infections resulting in renal stones, ultrasonographic monitoring for chronic proximal urinary tract dilatation in tumors: rigorous atraumatic operative technique avoiding oedema.

[Failures observed after repair of the pyeloureteric junction in children based on a series of thirteen cases].

We report a series of 13 infants with failed surgery for pyeloureteric junction (PUJ) obstruction. Failure was defined as the necessity for further surgery, either refashioning of the anastomosis or nephrectomy. These infants were part of a series of 306 with 322 PUJ. Of the 258 surgically treated infants, 232 (90%) had a post operative course without complication or need for reoperation. The failure rate was significantly higher in infants operated before the age of 4 months (8/65: 12.3%) when compared with those over 4 months of age (5/193: 2.59%). The use of postoperative drainage via a nephrostomy significantly reduced the percentage of early complications (e.g. fistula) but did not affect the final failure rate. The severity of the obstruction at presentation correlated with a bad outcome after reoperation. Of the cases which resulted in failure after reoperation (7/258: 2.7%) all occurred in cases of severe obstruction with parenchymal damage. While the failure of surgery is often evident early (persistant fistula, urinoma, non-functioning kidney on IVP) this may only become obvious some years later. Reoperations were successful in half the cases irrespective of the time between the initial operation and the reoperation. Long term follow-up of all infants operated for PUJ obstruction is recommended.

[Ureteropelvic junction syndromes: antenatal diagnosis].

Seventy-four hydronephrosis by uretero-pelvic obstruction, discovered by antenatal real-time ultrasound, have been managed on sixty-one children. Three groups, with a specific management, are distinguished. The minimal forms have been only watched over (15 cases). The average forms have been operated (49 cases); considering the results (3 immediate complications and 2 early stenoses), it seems better to wait for 4 months to operate and to place a drain in renal cavities. In major forms (silent kidney on IVP), the diagnosis and therapeutic management use the percutaneous nephrostomy (10 cases). The interest of antenatal diagnosis of uretero-pelvic obstructions is to allow to operate, not only before the renal deterioration emphasizes, but principally before septic complications.
