Urinary tract obstruction is a common major cause of acute and chronic renal insufficiency. Obstructive uropathy is a condition common to all age groups, even very early and late in life. Regardless of the age of obstruction, the renal response involves progressive tubular dilation, tubular atrophy, and interstitial fibrosis.

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.

Angiotensin II plays a pivotal role in the progression of renal diseases, including obstructive nephropathy. Increasing levels of angiotensin II in obstructive nephropathy upregulate the expression of several factors: transforming growth factor-beta1 (TGF-beta1), tumor necrosis factor-alpha (TNF-alpha), platelet-derived growth factor (PDGF), insulin ...

Fetal lower urinary tract obstruction
Seminars in Fetal and Neonatal Medicine, 2007Fetal lower urinary tract obstruction affects 2.2 per 10,000 births. It is a consequence of a range of pathological processes, most commonly posterior urethral valves (64%) or urethral atresia (39%). It is a condition of high mortality and morbidity associated with progressive renal dysfunction and oligohydramnios, and hence fetal pulmonary hypoplasia.

Non‐dilated urinary tract obstruction
Medical Journal of Australia, 1992To describe the occurrence of obstructive uropathy in the absence of dilatation of the urinary tract.Five cases of non-dilated obstructive nephropathy are described. All patients were uraemic on presentation. Obstruction was caused by retroperitoneal malignancy in two patients and uric acid lithiasis in the remaining three.

Upper Urinary Tract Obstructions
2003The advent of prenatal ultrasound (US) has enabled the physician to diagnose urinary tract abnormalities with far greater frequency than previously. Pelvi-ureteric junction (PUJ) and uretero-vesical junction (UVJ) obstruction are the most common causes of hydronephrosis detected antenatally.

Fetal Lower Urinary Tract Obstruction
Clinics in Perinatology, 2009The authors present an overview of the prenatal diagnosis, evaluation, contemporary intervention, and antenatal management of lower urinary tract obstruction. They review early experimental models that confirmed the relation between urinary tract obstruction and renal fibrocystic dysplasia and that early in utero relief of the obstruction could prevent

Abstract Obstruction of the urinary tract can occur in the upper or lower tract. Possible sites and causes of obstruction are shown in Figure 1. Lower tract obstruction is almost exclusively a disease of males, whereas upper tract obstruction occurs in both sexes. Lower urinary tract symptoms occur in 25% of men over the age of 50 years.

Urinary Tract Obstruction in Children
The Journal of Urology, 1995Perinatal identification of children with congenital urinary obstruction has challenged our understanding of the pathophysiology and clinical treatment of many children with hydronephrosis.A critical review of recent reports relating to congenital urinary obstruction in children was performed in an attempt to integrate clinical and experimental ...

Lower urinary tract obstruction
1958Whereas in adult urological practice disorders of one organ, the prostate gland, account for a high proportion of all cases with lower urinary obstruction, in children a greater variety of obstructive lesions may be found and in most diagnosis is only possible as a result of special urological investigation.
