The urinary tract can become obstructed by various disease processes, including tumours. Obstruction at any level of the urinary tract can impair the free flow of urine and may be partial or complete, and unilateral or bilateral. Bilateral obstruction usually occurs at the level of the bladder or lower. Retroperitoneal fibrosis and extrinsic compression of both ureters by a malignancy are exceptions. Children are affected by congenital vesicoureteric junction obstruction or pelvi-ureteric junction obstruction. Young adults suffer stone disease. The elderly are prone to urothelial cancers, and older men to bladder outflow obstruction. Retroperitoneal fibrosis is an inflammatory condition that typically affects men over 50 years of age. Diagnosis should be confirmed by biopsy to exclude a lymphoma or malignancy.

Outflow System

Obstructive nephropathy can manifest as either a sudden or an insidious decline in renal function, which can be can halted or even reversed by relief of obstruction. Obstruction can be due to anatomical or functional abnormalities of the urethra, bladder, ureter, or renal pelvis, which may be congenital or acquired, and it can also occur as a consequence of diseases extrinsic to the urinary tract. Although dilatation of the outflow system proximal to the site of obstruction is a characteristic finding, widening of the ureter and/or pelvicalyceal system does not necessarily indicate the presence of obstruction, and flow may be obstructed without such dilatation....

Loin Pain

This chapter covers upper tract obstruction, loin pain, and hydronephrosis. A comprehensive discussion of causes and management of unilateral and bilateral hydronephrosis is included. The pathophysiology of renal obstruction is detailed, including the physiology of urine flow from the kidney to the bladder. An overview of the management of non-pelviureteric junction obstruction (PUJO) ureteric strictures is included, including minimally invasive treatment options. The causes of retroperitoneal fibrosis are outlined, and this fourth edition includes the newer diagnosis of IgG4-related disease (causative in up to half of previously considered idiopathic cases). Common presentations, investigation, and management options are detailed, including both emergency management and longer-term treatments.

Normal Urine

Obstructive nephropathy is a structural or functional hindrance of normal urine flow, sometimes leading to renal dysfunction. Urinary tract obstruction can result from congenital (anatomic) lesion or can be caused by trauma, neoplasia, calculi, inflammation or surgical procedures, although most childhood obstructive lesions are congenital.The clinical features in most of the patients are due to consequences of the obstruction2. Obstruction of the urinary tract generally causeshydronephrosis, which is typically asymptomatic in its early phase. Renal USG gives information about urinary tract dilatation, renal cortical thickness, calyx size, diameter of pelvis, ureter, bladder thickness, tumor & calculi and doppler USG for evaluation of aberrentvessles. Once obstructive nephropathy has been identified therapy focuses on the rapid restoration of normal urine flow either by medical or surgical intervention.Bangladesh J Child Health 2017; VOL 41 (2) :117-124

Obstructive Nephropathy

Several terms usually describe obstruction of the urinary tract and its consequences such as hydronephrosis, obstructive uropathy, and obstructive nephropathy. Obstruction can be due to anatomical or functional abnormalities of the urethra, bladder, ureter, or renal pelvis. These abnormalities can be congenital or acquired. Obstructive uropathy also can occur during the course of diseases extrinsic to the urinary tract. This is a reversible cause of renal impairment and calls for urgent diagnosis and treatment to prevent chronic irreversible renal scarring and consequent progressive chronic renal disease.
