Immunohistochemistry in Ureteropelvic Junction Obstruction and Its Correlation to Postoperative Outcome.

Aim: To investigate the correlation between the status of interstitial cells of Cajal (ICC) in ureteropelvic junction (UPJ) and the resected ureteric margin and the postoperative outcome of Anderson-Hynes pyeloplasty in UPJ obstruction (UPJO) and to compare the ICC in the UPJ and the resected margin of the normal ureter.

Materials And Methods: An observational study was conducted over a period of 2 years at the Department of Pediatric Surgery at Niloufer Institute of Women and Child Health. Children with intrinsic UPJO who underwent Anderson-Hynes dismembered pyeloplasty were included in the study.
