Ureteral triplication is a rare congenital anomaly of the urinary tract. We report a case of ureteral triplication with contralateral partial kidney duplication in a patient with right loin pain. The development and types of ureteral triplication and the features of type 2 ureteral triplication on intravenous urography and magnetic resonance urography are described.
Emphysematous pyelonephritis is a rare but life threatening infection of kidney that is characterized by gas formation within or around the kidney. We describe a case of emphysematous pyelonephritis as a consequence of inadequately treated pelvic-ureteric stone in a diabetic man and complement this with a brief review of the literature pertaining in particular to the management of this condition.
Adult giant hydronephrosis in a normally sited kidney is unusual during pregnancy. The most frequent cause is congenital obstruction at the ureteropelvic junction. Ultrasound accompanied by magnetic resonance imaging (MRI) are valuable in reaching the diagnosis, especially when clinical assessment of an abdominal mass is inconclusive regarding aetiology. We report a case of giant hydronephrosis in a woman who presented at 23 weeks of gestation with abdominal distension. She was managed conservatively. Unfortunately, the pregnancy was complicated by severe pre-eclampsia at 32 weeks of gestation, necessitating delivery via emergency caesarean section. She had a smooth postpartum recovery, and subsequently standard imaging was performed before nephrectomy. The literature and previously reported cases of giant hydronephrosis in pregnancy are reviewed.
A 6-year-old intact Persian cat was presented for the primary complaint of inappetence and weight loss. Irregular surface of
kidneys was palpated during physical examination. Abdominal radiograph findings were indicative of renomegaly. Ultrasonography
revealed multiple anaechoic structures within the renal parenchyma. The cortex, medulla and renal pelvis were unable to be
differentiated. Both radiographic and ultrasonographic findings were suggestive of polycystic kidney disease. Blood test revealed
normochromic, normocytic anaemia with azotaemia whereas urinalysis findings were hypostenuria and proteinuria, consistent of
chronic kidney disease due to polycystic kidney. Ultrasound is a useful antemortem diagnostic tool to diagnose polycystic kidney
disease in cats.
Diffusely-infiltrating mucinous adenocarcinoma of the renal pelvis associated with lithiasis and chronic gout is reported in a 61-year-old Malay man. The patient underwent left nephrectomy and vesiculo-lithotomy. This tumour is postulated to arise in response to chronic irritation of the urothelium.
Bilateral hydroureteronephrosis involves the dilatation of the renal pelvis, calyces and ureter; it develops secondary to urinary tract obstruction and leads to a build-up of back pressure in the urinary tract, and it may lead to impairment of renal function and ultimately culminate in renal failure. Although clinically silent in most cases, it can be diagnosed as an incidental finding during evaluation of an unrelated cause. In a minority of patients, it presents with signs and symptoms. Renal calculus is the most common cause, but there are multiple non-calculus aetiologies, and they depend on age and sex. Pelviureteric junction obstruction, benign prostatic hypertrophy, urethral stricture, neurogenic bladder, retroperitoneal mass and bladder outlet obstruction are some of the frequent causes of hydroureteronephrosis in adults. The incidence of non-calculus hydronephrosis is more common in males than in females. Ultrasonography is the most important baseline investigation in the evaluation of patients with hydronephrosis. Here, we report a rarely seen case of bilateral hydroureteronephrosis associated with a hypertrophied, trabeculated bladder in an adult male cadaver, suspected to be due to a primary bladder neck obstruction, and analyse its various other causes, clinical presentations and outcomes.
