A cover flap reduces the rate of fistula after urethroplasty whatever the severity of hypospadias.

OBJECTIVE: To determine which patients should benefit from the interposition of a well-vascularized flap between the neourethra and the penile skin and if it should be performed even in mild hypospadias. PATIENTS AND METHODS: A retrospective study on patients with a primary hypospadias repair was performed (2003-2017). Only patients undergoing urethroplasty based on the principle of a tubularization were selected to ensure comparable groups. Patients were assigned in two groups according to the use or not of a cover flap. Univariate analysis and adjusted logistic regression were used to evaluate the relation between postoperative complications, the severity of hypospadias, the use of flap and patients' characteristics. RESULTS: Three-hundred and seventy-six patients were included with anterior (59.3%), midshaft (27.4%) and posterior hypospadias (13.3%). The median follow-up was 54 months (24 months-17 years). The overall rate of fistula was 11.7% (n = 44). Comparing the outcome in children with flap (n = 217) to controls (n = 159) showed that the use of a flap reduces the rate of fistula (6.5 vs 18.9%, p < 0.001). Stratification of the study according to the phenotype reveals that the more severe the hypospadias, the more protective was the flap (OR = 2.6 for anterior, 5.5 for midpenile, 7.1 for posterior hypospadias). The flap remains nevertheless significantly effective whatever the phenotype (p < 0.05 for anterior, p = 0.01 for midpenile, p = 0.02 for posterior hypospadias). CONCLUSIONS: The more severe the hypospadias, the more effective is the cover flap to avoid fistula. It remains nevertheless suitable even in anterior hypospadias and the use of a cover flap should not be limited to the surgery of severe phenotypes.

Prenatal imaging of genital defects: clinical spectrum and predictive factors for severe forms.

OBJECTIVES: To report the clinical spectrum of genital defects diagnosed before birth, identify predictive factors for severe phenotypes at birth, and determine the rate of associated malformations. PATIENTS AND METHODS: A retrospective study (2008-2017) of 4580 fetuses, identified prenatally with abnormalities evaluated by our Reference Center for Fetal Medicine, included cases with fetal sonographic findings of abnormal genitalia or uncertainty of fetal sex determination. Familial, prenatal and postnatal data were collected via a standardised questionnaire. RESULTS: In all, 61 fetuses were included. The positive predictive value (PPV) of the prenatal diagnosis of genital defects was 90.1%. Most cases were 46,XY-undervirilized boys, 42 cases (68.8%), which included 29 with mid-penile or posterior hypospadias, nine with anterior hypospadias, and epispadias, micropenis, scrotal transposition, and buried penis (one each). In all, 46,XX-virilized girls were identified in seven cases (11.5%), which included four with congenital adrenal hyperplasia, two with isolated clitoromegaly, and one with ovotestis. Other defects included prune belly syndrome and persistent cloaca (six cases). Early detection during the second trimester (58.1% vs 18.8%, P = 0.03), intra-uterine growth restriction (IUGR) (45.2% vs 9.1%, P = 0.06), and curvature of the penis (38.7% vs 0%, P = 0.02), were more frequently related to severe defects in male newborns. Associated malformations (14 cases, 22.9%) and genetic defects (six) were frequent in undervirilized boys. CONCLUSION: Prenatal imaging of genital defects leads to a wide range of phenotypes at birth. Its PPV is high and extra-urinary malformations are frequent. Early diagnosis during the second trimester, associated IUGR, and curvature of the genital tubercle, should raise suspicion of a severe phenotype and may justify delivery near a multidisciplinary disorders/differences of sex development team.

Management of nonparasitic splenic cysts in children: A French multicenter review of 100 cases.

BACKGROUND: The management of nonparasitic splenic cysts (NPSC) remains controversial. Surgical resection is indicated for symptomatic or complicated forms, but no guidelines are available for asymptomatic NPSC. The aims of this study were to evaluate the management of NPSC in French hospitals and to analyze the results of management. METHODS: We conducted a retrospective multicenter study from January 2004 to December 2014 in 16 university hospitals in France. Patients with a follow-up less than 6months were excluded. Data were extracted from the medical reports. RESULTS: One hundred patients were included. Median follow-up was 12.8months. No complications were observed for NPSC smaller than 5cm. The size of NPSC increased significantly between the ages of 10 and 12years. Fifteen patients were under observation; 58.3% of cysts decreased in size and 41.7% remained stable. Among the 85 operated patients, no recurrence occurred in the splenectomy group, while 11 recurrences were observed in the cystectomy group (57.9%), 3 of which required redo surgery. CONCLUSIONS: Observation is a safe treatment option for asymptomatic NPSC smaller than 5cm. Surgery is indicated for symptomatic patients, and can be proposed for asymptomatic NPSC larger than 5cm. Laparoscopic partial splenectomy is the technique of choice. Follow-up must be continued until the end of puberty. LEVELS OF EVIDENCE RATING: Level III.

Quality of life and functional outcome of male patients with bladder-prostate rhabdomyosarcoma treated with conservative surgery and brachytherapy during childhood.

PURPOSE: The aim of this study was to report the long-term results of a conservative local treatment of male patients with bladder-prostate rhabdomyosarcoma (BPRMS) focusing on their outcome and quality of life (QoL). METHODS AND MATERIALS: From 1991 to 2007, 27 male patients were treated by a single team, according to the ongoing European protocols. Surgical procedure was partial cystectomy or partial prostatectomy or both, followed by low-dose-rate interstitial brachytherapy. Three patients died of metastases and two were excluded; 22 patients, who were long-term survivors with their bladder, received a QoL questionnaire derived from the International Workshop on BPRMS. Urodynamic studies were performed when patients had abnormal continence. RESULTS: Median age at surgery was 24 months (14 months-11 years). Median followup after surgery was 10 years (5-21 years); 18 male patients (77%) completed the questionnaire at a median age of 13 years (7-25 years); 13 considered themselves as having a normal QoL, with normal urinary continence (9 of 13) or very rare diurnal dribbling (4 of 13). Four male patients had frequent diurnal dribbling requiring protection for three of them and one was submitted to intermittent catheterism for a postoperative neurogenic bladder. Urodynamic studies were performed in 11 patients with urinary disturbance, often revealing detrusor sphincter dyssynergia. All pubertal patients considered themselves as having normal erections. Three sexually active patients reported having satisfying sex and orgasms. Two patients had normal ejaculations. CONCLUSIONS: The majority of long-term male survivors (76%) within this cohort considered themselves as having a normal QoL after the combined conservative local treatment of their BPRMS.

Effect of sex and gestational age on neonatal body composition.

To determine the effects of length of gestation and sex on infant body composition, air displacement plethysmography was performed in forty-six full-term neonates at 3 d of life and during the week prior to hospital discharge in 180 preterm neonates. Fat mass, as a percentage of body weight, was higher in preterm than in term infants (13.4 (SD 4.2) v. 10.1 (sd 3.7) %, respectively; P= 0.001). The absolute amount of fat mass did not differ between preterm and full-term newborns (323 (SD 126) v. 335 (SD 138) g; P= 0.58), whereas lean body mass was lower in preterm than in term infants (2055 (SD 280) v. 2937 (SD 259) g, respectively; P< 0.001). Among full-term infants, fat mass was higher in females than in males (11.1 (SD 3.7) v. 9.0 (SD 3.3) %, respectively; P= 0.047), whereas we did not observe any sex difference in preterm infants (13.5 (SD 4.1) v. 13.4 (SD 4.3) %; P= 0.89). Our data suggest that by the time they are discharged from hospital: (1) preterm infants have a higher percentage of body fat than term neonates and (2) this is presumably due to a lesser accretion in lean body mass in the first few weeks of extra-uterine life, particularly in boys.
