RESULTS
Four patients were male and 6 of the 7 presented with gross hematuria. Ultrasound (US) was the
most common imaging modality, showing an intravesical polyps mainly in the trigone. MRI was
performed in 4 cases and revealed a mass with heterogeneous low-intermediate signal intensity in
T1 and T2-weighted sequence. All the lesions were solitary. Transurethral resection of the bladder
wall was performed in all cases. Histological studies showed grade-I TCCB (urothelial papilloma)
in all cases, and one patient had two recurrences with a final histological result showing grade-II
TCCB, treated with installation of Amyticine. All patients were alive with no evidence of disease after
a median follow-up of 8.3 years.
CONCLUSIONS
Urothelial tumors are likely to manifest as hematuria, occur as solitary lesions and are gener-
ally low grade. These lesions have low recurrence potential with extremely favorable prognoses.
Endoscopic treatment in urothelial tumor proved effective, with the necessity of a regular follow up
either by US or cystoscopy in atypical aspect.

PURPOSE
Secondary pseudohypoaldosteronism (S-PHA) is a life-threatening condition affecting young chil-
dren with urinary tract malformation (UTM), but remains unfamiliar to pediatric urologists. We aim
to emphasize the diagnosis S-PHA in children with urological issue, and to propose a management
based on the published data.
MATERIAL AND METHODS
We retrospectively reviewed the cases of S-PHA related to urinary tract malformation from our
institution, and we performed a MEDLINE review from the literature.
RESULTS
Including the 4 cases from our institution, 116 cases of S-PHA associated with UTM were reviewed.
One hundred and six were aged below 6 months. A urinary tract infection (UTI) was associated in
105 cases (91 %). All types of UTM were represented. When no UTI is associated, S-PHA was
related to severe or bilateral UTM. In 89 cases (76.5 %), S-PHA resolved with medical treatment
associating electrolyte correction and appropriate antibiotic therapy. In cases of UTM needing im-
mediate surgery, the surgical intervention also resolved S-PHA.
CONCLUSIONS
S-PHA affects children with UTM under the age of 6 months. Associated UTI and bilateral or severe
UTM are at higher risk of developing S-PHA. Serum electrolyte balance must be checked in children
presenting UTM when undergoing urological surgery, and when presenting UTI, before 6 months of
age. Congenital adrenal hyperplasia must be suspected. S-PHA resolve after electrolyte correction
and UTI treatment and/or surgery.
