Analysis of the Causes of Newborn Priapism: A Retrospective Clinical Study

Abstract

Priapism is a rare condition in the newborn. The aim of this study was to investigate the demographic, etiologic and clinical features of neonatal priapism. We retrospectively analysed the data of 11 patients diagnosed with neonatal priapism in the neonatal intensive care unit between 2000 and 2019. Priapism was defined as an erection in the neonatal period, lasting more than 4 hours. Etiological examinations revealed polycythemia in one (9.09%) patient, D-dimer elevation in three patients, and heterozygous methyltetrahydrofolate 667 gene mutations in one patient. Other patients were considered idiopathic. Detumescence was achieved in all 11 (100%) patients during the follow-up period. The median hospitalization duration was 6 (IQR [4, 8]; range, 2–9) days. The median follow-up duration was 38 (IQR [30, 42]; range, 13–94) months for patients followed-up in our hospital after discharge. Neonatal priapism is a rare condition. Successful treatment results can be achieved with conservative methods. Data acquired from our study showed that diseases with a tendency to hypercoagulation belong to the etiology by damaging penile microcirculation and make the response to conservative treatment more challenging.
