The Fate of Primary Nonrefluxing Megaureter: A Prospective Outcome Analysis of the Rate of Urinary Tract Infections, Surgical Indications and Time to Resolution

Abstract: Febrile urinary tract infection developed in 34% of patients with primary nonrefluxing megaureter within the first 6 months of life. Circumcision and continuous antibiotic prophylaxis significantly decreased febrile urinary tract infection rates in those infants. Ureteral diameter 17 mm or greater was significantly associated with a higher rate of surgical intervention. Overall 76% of megaureters resolved during a median followup of 19 months.

“…Four studies were conducted in Canada, [16][17][18][19] four in the U.S., [20][21][22][23] and one each were conducted in Germany, 24 Turkey, 25 and Italy. 26 Six studies 16,17,20,23,25,26 were prospective and five 18,19,21,22,24 retrospective. Following fulltext review, 84 articles were excluded because they were non-comparative studies, editorials, or case reports.…”

“…Four included studies were judged to be of high methodological quality (≥7 stars), [16][17][18][19] and seven of low quality (<7 stars) [20][21][22][23][24][25][26] (Table 1). A weighted Kappa of 0.97 (95% CI 0.93-1.0) was cal- culated for the NOS quality appraisal agreement.…”

“…Die Behandlung des POM hat sich in den letzten Jahrzehnten grundlegend geändert. Während noch vor 30 Jahren in über 80 % der Fälle eine Operation im Sinne einer Ureterreimplantation durchgeführt wurde, ist dieses Krankheitsbild heute eine Domäne konservativer Therapie unter Ausnutzung der spontanen Nachreifung des adynamen Segments mit dementsprechender Verbesserung des Abflusses [1,5,6]. Daher sollte heute die operative Therapie des POM die Ausnahme sein und ist in maximal 10 -20 % der Fälle noch notwendig.…”

“…Etwa nur 20-30 % der heute präpartal diagnostizierten Megaureteren benötigen eine chirurgische Korrektur [27][28][29]. Neben dilatierenden Refluxen und rezidivierenden fieberhaften Harnwegsinfektionen stellen der szintigrafisch detektierte Partialnierenfunktionsverlust < 30 %, die erhebliche und im Verlauf zunehmende Hydronephrose (Grad 3-4) sowie ein Ureterdurchmesser von > 1,33 cm statistisch signifikante, unabhängige prädiktive Faktoren für eine Operationsnotwendigkeit dar [29].…”
