A Study of Clinical Profile of Congenital Anomalies of Kidney and Urinary Tract (CAKUT) in a Tertiary Care Center.

Background  Congenital anomalies of the kidney and urinary tract (CAKUT) encompass a diverse array of disorders arising from developmental irregularities in the renal parenchymal development, disrupted embryonic migration of the kidneys, and the urinary collecting system. This study aimed to investigate the clinical presentations, patterns of obstructive and non-obstructive CAKUT, and associated extrarenal manifestations in affected children. Methods This observational study was conducted in the Department of Pediatrics, Acharya Vinoba Bhave Rural Hospital, Wardha. Ethical clearance was obtained, and the study included 105 diagnosed CAKUT patients aged from birth to 18 years. Data collection spanned from June 2022 to May 2024. Clinical features, antenatal findings, associated anomalies, estimated glomerular filtration rate (eGFR), and serum creatinine levels were recorded. Descriptive and inferential statistical analyses were performed using Stata software. Results Among the 105 participants, 81 (77.14%) were males, with a male-to-female ratio of 3.37:1. The mean age was 42.49 months. Forty-two individuals (40%) were asymptomatic, while the most common symptomatic presentation was the ventral opening of the urethra (24.76%). Extrarenal malformations were present in 35 subjects (33.33%), with undescended testis (25.71%) and congenital heart disease (CHD) (20%) being the most common. The antenatal diagnosis was made in 63.8% of cases. Obstructive uropathy was present in 42.86% of subjects, with a significant association between antenatal diagnosis and bilateral hydronephrosis. Medical management was provided to 41.9% of subjects, while 58.1% underwent surgical interventions. Conclusion The study highlights the clinical variability and diverse presentations of CAKUT in children, with a substantial proportion being asymptomatic. Early detection through antenatal screening and prompt intervention can potentially prevent or delay the progression to ESRD. The findings underscore the importance of comprehensive evaluation and targeted management strategies to address both renal and extrarenal manifestations of CAKUT.
