[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.
