Recent Urinary tract obstruction leading to acute kidney injury (AKI) is commonly associated with hydro ureter and hydro nephrosis, often accompanied by oliguria. AKI and the syndrome of Non- Dilated Obstructive Uropathy (NDOU) is well reported, however, it is not common, accounting for less than 4% of obstructive uropathy cases. Our recent experience with two cases of NDOU seen within the span of six months may imply otherwise. We present two cases of obstructive uropathy without sonographic features of obstructive uropathy with acute renal failure. Two elderly male patients presented at Royal Bahrain Hospital Nephrology Centre with an acute rise in serum creatinine, without active urinary sediment or proteinuria. Imaging studies showed normal size kidneys without hydronephrotic changes. Initially, they were diagnosed with prerenal azotemia secondary to volume depletion, and they were treated with intravenous fluids which failed to improve the kidney function. Repeated imaging showed bladder fullness with prostate hypertrophy, therefore NDOU was diagnosed. Both patients’ urinary obstruction was relieved resulting in recovery of the kidney injury.
