title: Symptomatic spontaneous pneumothorax in term newborn infants.
abstract: The association between congenital major urinary tract anomalies (CMUTA) and spontaneous pneumothorax in term newborn infants (SPTNI) is controversial. We conducted a case-control study to test the hypothesis that SPTNI is associated with CMUTA. We compared 80 term infants with spontaneous pneumothorax to 80 healthy control infants. We recorded risk factors, clinical course, therapy, and outcome. Only 1 infant of 60 infants (1.7%) had CMUTA with SPTNI, as revealed by renal ultrasound studies. This is comparable to the 1.4% rate reported for CMUTA in healthy newborn infants by Steinhart et al. ([1988] Pediatrics 82:609-614). SPTNI were significantly more likely in males with higher birth weights and with vacuum delivery. Sixty-seven (84%) infants with SPTNI had follow-up for a mean and median of 46.4 and 39 months, respectively (range, 1-126 months), without manifesting any renal or pulmonary complications.
