Introduction: Pelviureteric junction obstruction (PUJO) is an important cause of upper urinary tract obstruction. We aimed to review the pattern of presentation and management outcomes of patients diagnosed with PUJO.

Methods: This retrospective observational study included 63 children aged 47 days to 14 years, diagnosed with Pelviureteric Junction Obstruction (PUJO) at Bangabandhu Sheikh Mujib Medical University (BSMMU) from January 2016 to December 2020. Patients with complete clinical records were included, and informed consent was obtained from parents or guardians. Data on demographics, clinical presentation, imaging, and treatment outcomes were analyzed using SPSS version 20.

Result: The 63 patients ranged from 47 days to 14 years old, with a median age of 2.7 years. The cohort included 48 males and 15 females, with a maleto- female ratio of 3.2:1. Unilateral PUJO was present in 90% of cases, with 30% right-sided and 60% left-sided. The most common symptom was occasional flank swelling with pain (83%), and 17% presented with a urinary tract infection. All patients had normal renal function at the time of surgery, where dismembered Anderson–Hynes pyeloplasty with a D-J stent was performed. Post-pyeloplasty, 95% of patients showed improved drainage and renal function, while 5% required nephrectomy.

Conclusion: PUJO is a common cause of urinary obstruction in children. Most of our patients underwent Anderson–Hynes pyeloplasty with satisfactory outcomes.
