Objective . To evaluate diagnosis, age of referral, karyotype, and sex rearing cases with disorders development (DSD) ambiguous genitalia. Methods Retrospective study during 23 years at outpatient clinic a referral center. Results There were 408 cases; 250 (61.3%) 46,XY 124 (30.4%) 46,XX 34 (8.3%) had chromosomes abnormalities. 189 (46.3%) testicular DSD, 105 (25.7%) ovarian 95 (23.3%) gonadal (DGD), 19 (4.7%) complex malformations. The main etiology DSD was salt-wasting 21-hydroxylase...
Context: Differentiation of testicular tissue in 46,XX individuals is seen either XX males, the majority them with SRY gene, or individuals, usually SRY(−), ovotesticular disorder sex development (OT-DSD). Although they are sporadic cases, there some reports on familial recurrence, including coexistence maleness and OT-DSD same family. Objective: We report a case SRY(−) monozygotic twins genital ambiguity. Methods: Hormonal evaluation included testosterone, FSH, LH measurements. gene was...
Introduction: This study evaluated the surgical details and outcomes of fetal myelomeningocele (MMC) repair using a minimally invasive fetoscopic approach with uterine exposure. Methods: retrospective case series examines consecutive fetuses who underwent spina bifida performed by single team. The pregnant women's demographic data, technical aspects, complications, neonatal were analyzed. Results: From 2019 to 2022, 32 MMC at an average gestational age 25.2 0.9 weeks (range 23.2 - 26.6)....
To report a series of children with pelviureteric junction obstruction (PUJO) due to lower polar crossing vessels who underwent laparoscopic vascular transposition. In order confirm the relief and avoid unnecessary additional procedures, we suggest performing an intraoperative measure ureteral opening pressure.From January 2007 2014, 11 laparoscopy treat well-documented PUJO by vessels. first 7 cases, careful dissection that were transposed cranially in pelvis. last 4 percutaneous needle was...
Deficiency of the enzyme P450 oxidoreductase is a rare form congenital adrenal hyperplasia with characteristics combined and partial impairments in steroidogenic activities, as transfers electrons to CYP21A2, CYP17A1, CYP19A1. It results disorders sex development skeletal malformations similar Antley-Bixley syndrome. We report case 9-year-old girl who was born virilized genitalia (Prader stage V), absence palpable gonads, 46,XX karyotype, hypergonadotropic hypogonadism. During first year...
OBJECTIVE: Report the results of laparoscopic upper-pole nephroureterectomy in infants. MATERIALS AND METHODS: Six consecutive infants underwent 7 nephroureterectomy. Pre and postoperative evaluation included renal sonography, voiding cystourethrogram scintigraphy. All showed exclusion. Surgery was performed through a transperitoneal approach with full flank position all Three or 4 ports were used according to necessity retracting liver. The distal ureter ligated close bladder whenever...
Introduction and objective: Correction of gastroschisis may be accomplished by either primary or staged closure even delayed after the use a preformed silo. However, there is neither consensus on best approach nor established criteria to favor one method over other. The aim this paper was investigate role intravesical pressure (IVP) as tool prevent abdominal compartment syndrome in newborns undergoing correction wall defects. Methods: We retrospectively analyzed 45 with whom trans-operative...
Complications are frequently reported after hypospadias repair and there is a need to understand the factors that influence their occurrence.Data from boys with born between 2000 2020 were obtained International Disorders of Sex Development (I-DSD) Registry. Logistic regressions, fisher's exact tests spearman's correlation performed on data assess associations clinical complication rates.Of 551 eligible boys, available 160 (29%). Within cohort, median (range) External Masculinization Score...

Abstract Background: Ovotesticular disorder of sex development (OT-DSD) (true hermaphroditism) is an anatomopathological diagnosis based on the findings testicular and ovarian tissues in same subject, gonad (ovotestis), or separate gonads. OT-DSD a rare cause ambiguity, most common karyotype 46,XX; mosaics chimeras are found only 10%–20%. Aim: To report case patient with constitution. Case report: A 2-month-old child male assignment was referred to our clinic for investigation ambiguity. He...
The rapid development of video surgery and minimally invasive surgical techniques prompted many studies on the methods teaching these to young surgeons in training. However, characteristics a short-term course that is both easily accessible efficient for this group remain controversial. To investigate issue, training method was proposed first year residents, using inexpensive handmade wooden simulation boxes with students smartphones as cameras. Its effectiveness evaluated, well possible...

A gonadal tumor was diagnosed in the first months of life a patient with genital ambiguity, 45,X/46,XY karyotype, and mixed dysgenesis. Gonadal biopsies at age 3 revealed dysgenetic testes gonadoblastoma on right testis. Even though tumors are rare childhood, this case indicates that prophylactic removal gonads should be performed as early possible, especially when female sex is assigned to Y-chromosome sequence.

Dilation of urinary tract occurs without the presence obstruction. Diagnostic methods that depend on renal function may elicit mistaken diagnosis. Whitaker (1973) proposed evaluation pressure submitted to constant flow. Other investigators perfusion pelvis under controlled pressure, making method more physiological and reproducible. The objective present study was evaluate results anterograde measurement (APM) children with persistent hydronephrosis after surgery suspected obstruction.Along...
To evaluate, in a sample of patients with disorders sex development (DSD), data related to the age at referral and their correlation initial complaints, gender referral, defined after diagnosis etiological diagnosis.Retrospective review first consultation reason for it, social diagnosis, karyotype all cases treated DSD outpatient clinic between 1989 2016. Cases that did not involve diagnoses do usually ambiguous genitalia, thus requiring specialized monitoring, were excluded.Of 1793 cases,...
