Postrenal Failure
Aka: Postrenal Failure, Postrenal Azotemia, Acute Postrenal Failure, Hydronephrosis, Urinary Tract Obstruction, Postrenal Obstruction, Urinary Outflow Obstruction- See Also
- Epidemiology
- Accounts for 1-10% of Acute Renal Failure cases
- More common in elderly
- Pathophysiology
- Urinary Tract Obstruction
- Results in renal Pelvis dilatation
- Progressive decrease in Renal Function
- Increased intratubular pressure
- Decreased capillary filtration pressure
- Causes
- Symptoms
- Abdomen or Groin Pain (colic-type attacks)
- Signs
- Labs
- See Renal Function
- Urine Sediment
- Normal sediment
- Hematuria
- Pyuria
- Crystals
- Diagnostic Testing
- Post-void residual >100 ml
- Indicates Bladder outlet obstruction
- Ultrasound or Intravenous Pyelogram
- Dilated ureters or renal Pelvis
- Abdominal CT or Abdominal MRI
- Percutaneous nephrostomy drainage trial
- Post-void residual >100 ml
- Management
- See Acute Kidney Injury Management
- Exclude reversible causes rapidly
- Renal Function recovery reflects obstruction duration

Definition (CHV) | water retention in the kidney |
Definition (CHV) | water retention in the kidney |
Definition (NCI) | Collection of urine in the renal pelvis that results in dilatation of the renal pelvis and calyces. It is caused by obstruction of urine flow, nephrolithiasis, or vesicoureteral reflux. Signs and symptoms include flank pain, nausea, vomiting, fever, and dysuria. |
Definition (NCI_NCI-GLOSS) | Abnormal enlargement of a kidney, which may be caused by blockage of the ureter (such as by a kidney stone) or chronic kidney disease that prevents urine from draining into the bladder. |
Definition (CSP) | distention of the pelvis and calices of the kidney with urine, as a result of obstruction of the ureter, with accompanying atrophy of the parenchyma of the organ. |
Definition (MSH) | Abnormal enlargement or swelling of a KIDNEY due to dilation of the KIDNEY CALICES and the KIDNEY PELVIS. It is often associated with obstruction of the URETER or chronic kidney diseases that prevents normal drainage of urine into the URINARY BLADDER. |
