ESPU Congress 2018 - Abstract Book

26 29 th CONGRESS OF THE ESPU 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. 14:08–14:10 S2-5 (CP) TRANSIENT PSEUDOHYPOALDOSTERONISM: A POTENTIALLY SEVERE CONDITION AFFECTING INFANTS WITH URINARY TRACT MALFORMATION Xavier DELFORGE  1 , Elodie HARAUX  1 , Axelle CAULIEZ  2 , Karine BRAUN  2 , Guy KONGOLO  3 and Philippe BUISSON  1 1) CHU Amiens, Pediatric surgery, Amiens, FRANCE - 2) CHU Amiens, Pediatric endocrinology, Amiens, FRANCE - 3) CHU Amiens, Pediatric intensive care unit, Amiens, FRANCE 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.
