Symptomatic uraemia from bilateral obstructive uropathy secondary to metastatic urinary bladder cancer showing only unilateral hydronephrosis: a case report
نویسنده
چکیده
Bilateral hydronephrosis is classic for supravesical obstructive uropathy causing uraemia with dual functioning kidneys. Recently, a patient presented with uraemia and metastatic urinary bladder carcinoma but only unilateral right-sided hydronephrosis. A right ureteral stent was placed retrograde and no further intervention was planned since the left kidney appeared normal, and since the left ureteric orifice was not visualized. We insisted on a left percutaneous nephrostomy which was successful with prompt urine return. A left nephrostogram revealed unrecognized hydroureter/hydronephrosis. Following haemodialysis, kidney function normalized at 3 weeks. For symptomatic uraemia from obstruction, an antegrade and/or a retrograde decompression must be attempted bilaterally to improve renal salvage.

Non-traumatic, spontaneous urinary bladder rupture is a rare complication of urethral stricture. Furthermore, its symptoms are often nonspecific, and misdiagnosis is common. The authors experienced a case of urethral stricture with spontaneous bladder rupture and bilateral hydronephrosis, mimicking obstructive uropathy attributed to cancer metastasis. A 55-year-old woman was admitted with abdom...

A congenital bladder diverticulum (CBD) is caused by inherent muscular weakness instead of obstruction of the bladder outlet. The major clinical conditions are recurrent urinary tract infection (UTI) and voiding dysfunction. This report describes a 15-year-old male adolescent who developed sudden visual disturbance resulting from hypertensive retinopathy. The cause of hypertension was bilateral...

Obstructive uropathy is defined as structural obstruction to urine flow along the urinary tract. It can lead to dilatation of renal pelvis and calyces. (1). However renal pelvis can be dilated without obstruction. Therefore hydronephrosis and dilated renal pelvis are not synonymous terms. The damage to renal tissue caused by these conditions often leads to obstructive nephropathy contributing t...

INTRODUCTION Prostatic hyperplasia is the most frequent tumor in men older than 50 years of age. Bilateral hydronephrosis secondary to benign prostatic hypertrophy is a rare condition most often due to vesicoureteral reflux. Herein we report a case of a patient with bilateral hydronephrosis with distal ureter obstruction caused by detrusor hypertrophy due to prostatic hyperplasia, our analysis ...
