AIM To use high field proton nuclear magnetic resonance spectroscopy (1H NMR) to characterise the low molecular weight metabolite composition of neonatal and fetal urine in relation to gestational age and perinatal outcome. METHODS The first urine passed by two neonatal groups, six full term and five preterm infants with normal renal function, was analysed by 1H NMR and compared with fetal ur...

Inguinal herniation of ureter is an uncommon finding that can potentially lead to obstructive uropathy. We report a case of inguinal herniation of ureter discovered incidentally during workup for acute renal failure and ultrasound finding of hydronephrosis.

Retroperitoneal fibrosis (RPF) is a relatively rare disease which shows a periaortic mass in the retroperitoneal area and predisposes to an obstructive uropathy. We report a case of idiopathic RPF occurring in a patient who was suspected of impending rupture of abdominal aortic aneurysm. A 60-year-old male, with a 2-week history of abdominal pain, was transferred for evaluation of the periaorti...

We report a case of patient with documented SLE who displayed dysuria, gastrointestinal (GI) symptoms and renal insufficiency associated with the unusual occurrence of bilateral hydroureteronephrosis due to urterovesical junction stricture (obstructive uropathy). Pathologic investigations disclosed chronic interstitial cystitis (IC) with evidence of focal immune complex deposition in the blood ...

BACKGROUND: Obstructive uropathy and hydronephrosis are common complications of cervical cancer. In order to provide an alternative route due ureteral obstruction, urinary diversion was performed. Urinary procedures a therapeutic option for obstructive but their effectiveness is remain unclear. There limited data that support as treatment obstruction improve overall survival progression-free su...

A 49-year-old woman had a vena caval filters inserted having suffered multiple pulmonary emboli and a large upper gastrointestinal bleed. She re-presented five years later with loin pain and obstructive uropathy. She was found to have a right pelvi-ureteric obstruction due to inferior vena caval wall perforation from the vena caval filter.

Anterior urethral valve is a rare congenital anomaly that can cause obstructive uropathy. Herein, we report a case of an anterior urethral valve that led to the development of febrile urinary tract infection in a neonate.

Reports on foreign bodies within the ureter are extremely rare in the literature. Herein, we present a case of a foreign body in a ureter, specifically a particle of glue resulting from transarterial embolization of a renal pseudoaneurysm secondary to percutaneous nephrostomy. Emergent transarterial embolization was required due to life-threatening active bleeding of the pseudoaneurysm. However...

Background. A rare but morbid form of extrapulmonary tuberculosis (TB), genitourinary TB is an important cause of obstructive uropathy and is likely underdiagnosed in pregnancy. Case. A 30-year-old primigravida undergoing treatment for active pulmonary TB presented with anuria at 13-14-weeks gestation. Bilateral ureteral strictures above the level of the ureterovesicular junctions were seen on ...
