Using a nationwide database in South Korea, this study examined the maternal and neonatal outcomes among women undergoing maintenance hemodialysis, with a particular focus on dialysis modality and treatment patterns. Methods: This population-based retrospective cohort study utilized data from the Korean National Health Insurance Service database. The study included all live births between 1 January 2014 and 31 December 2022, linked to mothers who underwent hemodialysis at least twice per week during pregnancy. Results: Between 2014 and 2022, in the Republic of Korea, 31 live births were recorded among 29 women undergoing hemodialysis. The mean maternal age at delivery was 36.1 \u00b1 4.94 years, and most patients had significant comorbidities, including hypertension (79.3%), and diabetes mellitus (48.3%). Cesarean section was the predominant mode of delivery (75.9%). Pregnancy-related complications included preterm delivery (48.4%), preeclampsia (16.1%), and gestational diabetes (16.1%). A total of 16.1% of the neonates had atrial septal defects. During the peripartum period, 93.1% of deliveries occurred at tertiary care centers, and trimester-wise escalation in dialysis frequency was observed. Conclusions: This study provided real-world data on pregnancy-related outcomes among women with ESKD undergoing maintenance dialysis in Korea. Given the rarity of this clinical condition, our findings may serve as a valuable reference for the management of pregnant women with ESKD.<\/jats:p>","DOI":"10.3390\/jcm15124621","type":"journal-article","created":{"date-parts":[[2026,6,15]],"date-time":"2026-06-15T08:57:58Z","timestamp":1781513878000},"page":"4621","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Pregnancy Outcomes and Associated Complications in Patients Undergoing Hemodialysis and Their Neonates: A Nationwide Study in South Korea (2014\u20132022)"],"prefix":"10.3390","volume":"15","author":[{"given":"Jee Young","family":"Lee","sequence":"first","affiliation":[{"name":"Devision of Nephrology, Department of Internal Medicine, Konkuk University School of Medicine, Konkuk University Medical Center, Seoul 05030, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sang Hyun","family":"Park","sequence":"additional","affiliation":[{"name":"Department of Clinical Pharmacology, Konkuk University Medical Center, Seoul 05030, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2669-3621","authenticated-orcid":false,"given":"Hye Won","family":"Park","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Konkuk University Medical Center, Konkuk University School of Medicine, Seoul 05030, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5972-3893","authenticated-orcid":false,"given":"Kyung Won","family":"Kim","sequence":"additional","affiliation":[{"name":"Devision of Nephrology, Department of Internal Medicine, Konkuk University Medical Center, Seoul 05030, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tae-Eun","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Clinical Pharmacology, Konkuk University Medical Center, Seoul 05030, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,6,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"404","DOI":"10.23876\/j.krcp.24.035","article-title":"Mortality in patients receiving renal replacement therapy in South Korea","volume":"45","author":"Kim","year":"2026","journal-title":"Kidney Res.
