Abstract Title:Role of Radiological Imaging in the diagnosis of PUJ obstruction in Pediatric age group.

Biography: Md. Didarul Islam obtained his MBBS degree from Dhaka university in 1990, MD ( Radiology and Imaging) from Dhaka university in 2006. Worked as Radiologist in National institute of ophthalmology and hospital, Dhaka. Worked as assistant professor (Radiology & imaging), Shaheed Suhrawardy Medical college.He engaged with teaching of post graduate medical students of different discipline of medical science. He was promoted to associate professor and retired from government job in 2024. Now working as a consultant radiologist in IBN Sina Diagnostic and consultation centre, Dhaka. He has five publications in National & international journal.

Research Interest: Ultrasonography, CT scan & MRI plays an important role in the diagnosis of PUJ obstruction in pediatric age group. Among all Ultrasound is the best modality for imaging, because it has no radiation hazards, no effects on movement during scanning, less costly, can be done in bed side. Some times to differentiate it from functional obstruction we need diuretic renogram study. Non dilated ureters cannot be visualized by ultrasonography, in that case CT urogram & MRI is helpful. There is typical pattern of dilatation of pelvi-caliceal systems of kidney in PUJ obstruction where pelvis is disproportionately more dilated than caliceal systems & conical in shape without dilatation of ureter. On the other hand hydronephrotic kidney other than PUJ obstruction produce proportionate dilatation of pelvicaliceal system. On the basis of this findings in imaging we can differentiate PUJ obstruction from other cause of obstruction.
