Prognosis concerning renal function seems to be mainly related to two factors: age at presentation and underlying diagnosis. Decompression of the urinary tract by urine extravasation produces the best results in terms of preservation of the renal function in LUT obstruction (75% in prenatal and 84% in postnatal cases); UUT obstruction however is associated with a good prognosis in the neonatal period (80% of preserved renal function) but with a severe impairment (only 20% of preserved renal function) in prenatally detected cases.

“…Since this original description, more than a hundred cases have been published in the literature, including some cases retrospectively identified from case reports pre‐dating Page’s discovery. Page kidney has been reported in all age groups, including pediatric, 7,8 adolescent, 9 and adult patients in association with multiple etiologies, including blunt trauma, iatrogenic intervention (including surgical complications 10–12 such as following ureteral surgery and post‐renal biopsy [both allograft 13–18 and native 19 kidney]), domestic violence, 20 and parenchymal renal disease 21,22 . The largest published series to date is an international literature review 19,23 …”

J Clin Hypertens (Greenwich). 2012;14:216–221. ©2012 Wiley Periodicals, Inc. The initial description of Page kidney, a form of renin‐mediated hypertension, included athletes with renal subcapsular hematoma after flank trauma. Subsequently, nontraumatic etiologies were identified. In this study, the authors compare traumatic and nontraumatic causes of Page kidney. All cases with hypertension attributable to renal hematoma at our institution from 1960 to 2010 were reviewed. Twenty‐six patients (9 trauma, 17 nontrauma), with a mean age of 36.7 years, were included. Trauma patients were younger (P<.001), had lower systolic blood pressures (P=.011), and higher baseline estimated glomerular filtration rate (eGFR), (P=.027) at presentation. No differences in presenting features, imaging, urinalysis, or pathology are noted. Nontrauma cases required more antihypertensive medications (P=.001) and had higher nephrectomy rates. eGFR improved in all, but more in, trauma cases (P=.05). Through the analysis of 26 cases of Page kidney, two distinct groups were identified. Trauma patients tended to be younger, male, have less renal impairment and lower systolic blood pressure. Nontrauma patients required more antihypertensive medications and had a higher nephrectomy rate. New‐onset hypertension occurred independent of etiology, calling for close surveillance of blood pressures.

“…The factors contributing to the formation of urinoma are rupture of the collecting system, distal obstruction and continued renal function 2 . If the collecting system becomes obstructed, the high backpressure provokes extravasation of the urine into the perinephric space via the rupture of a fornix 3 . The extravasated urine causes lipolysis and an inflammatory and fibrotic reaction, which may result in the formation of a fibrous sac around the collected urine.…”

Perinephric urinoma secondary to neurogenic bladder with vesicoureteral reflux: Report of an adult case

2003

View full text Add to dashboard Cite

We report a case of infectious perinephric urinoma in a 73-year-old woman who had a neurogenic bladder with vesico-ureteral reflux. The patient was admitted to our emergency room with right lumbago and high fever. Ultrasounds and computed tomography demonstrated a right large perinephric cystic mass, bilateral hydronephrosis and much residual urine. Percutaneous drainage of the cystic mass was performed with an indwelling urethral catheter. The content of the mass was urine infected with Escherichia coli. Antibiotic therapy was performed successfully and we then examined the cause of the urinoma. A urodynamic study demonstrated a low-compliance small bladder and detrusor-sphincter dyssynergia. A voiding cystourethrogram revealed right grade III vesicoureteral reflux. The patient was unable to be cleared with intermittent catheterization and had an indwelling urethral catheter inserted. In 1 year, the voiding cystourethrogram showed no vesicoureteral reflux and the patient was well with no evidence of recurrent urinoma without the urethral catheter. There have been only two reported cases of urinoma caused by neurogenic bladder with vesico-ureteral reflux in children and this is the first case reported in an adult.
