[Value of percutaneous nephrostomy in the management of posterior urethral valves in newborn infants].
OBJECTIVE
This study evaluates the place of percutaneous nephrostomy (PCN) in neonates with posterior urethral valves (PUV).


METHODS
11 neonates with PUV, 10 of which were diagnosed antenatally, were treated. PCN drainage was performed in 9 cases, prior to endoscopic resection. Six PCN were bilateral and 3 were unilateral, for the following indications: renal failure in 5 cases, severe infection in 2 cases, evaluation of a dilated kidney in 2 cases.


RESULTS
These PCN were left in place for an average of 18 days. Two cases of asymptomatic postoperative bacteriuria were observed. One nephrectomy and one cutaneous ureterostomy followed by reimplantation for megaureter were performed on the diverted kidneys.


CONCLUSIONS
PCN has become the method of upper tract diversion in most cases of neonatal PUV. In addition to the classical indications (severe urinary tract infection, renal failure), it allows perfectly safe resection of valves in the case of upper tract dilatation and assessment of the kidneys.
