RESUMO
OBJECTIVES: To compare the efficacy of temocillin with standard of care (SOC) for treatment of ESBL-producing Enterobacteriaceae (ESBL-E) febrile urinary tract infection (ESBL-E FUTI) in children. METHODS: A monocentric retrospective study of children hospitalized with confirmed ESBL-E FUTI from January 2015 to May 2022 was conducted, comparing clinical cure and a 3â month relapse between two groups of patients: 'exposed' patients (EP) and 'non-exposed' patients (NEP) to temocillin. EP received temocillin for at least 3â days. They were matched (1:1 ratio) on age group, sex and presence of uropathy with NEP who received SOC antibiotic therapy. RESULTS: Thirty-six temocillin-treated children (EP) were matched with 36 SOC children (NEP); 72.2% were under 2â years old (nâ=â52) and 75.0% had a congenital uropathy (nâ=â54). EPs had more FUTI history (97.2%, nâ=â35) than NEPs (61.1%, nâ=â22) (Pâ<â0.01). Clinical cure rate was 98.6% overall, with no difference between the two groups, as for the FUTI relapse rate, which was 37.1% for EPs versus 27.8% for NEPs (Pâ=â0.45). In bivariate analyses, factors associated with relapses were congenital uropathy (91.3% versus 66.7%, Pâ=â0.04) and subtypes of uropathy, with refluxing uropathy and posterior urethral valves being the more prevalent. Median duration of hospitalization was longer in the EPs (8.0 versus 5.0â days) (Pâ=â0.01). CONCLUSIONS: The high clinical cure rate and comparable outcomes suggest that temocillin may be an effective therapeutic alternative to standard treatment for ESBL-E FUTI in children.

PURPOSE: To describe the experience of performing ovarian tissue cryopreservation (OTC) before hematopoietic stem cell transplantation (HSCT), among girls/women with severe sickle cell disease (SCD)(SS or S/ß0-thalassemia) who are, besides the usual surgical risk, at risk of SCD-related complications during the fertility preservation procedure for improving their counseling and management. METHODS: This retrospective study included 75 patients (girls/women) with SCD who have had OTC before myeloablative conditioning regimen (MAC) for HSCT. Characteristics of patients and data on OTC, ovarian status follow-up, and results of ovarian tissue transplantation (OTT) were collected in medical records. RESULTS: At OTC, the median (IQR 25-75; range) age of the patients was 9.6 (6.9-14.1; 3.6-28.3) years, 56/75 were prepubertal, and no SCD or surgery-related complications occurred. The median follow-up post-HSCT was > 9 years. At the last follow-up, among prepubertal patients at HSCT, 26/56 were ≥ 15 years old and presented with a premature ovarian insufficiency (POI), except 2, including the patient who had received an OTT to induce puberty. Eight were 13-15 years old and presented for POI. The remaining 22 patients were under 13. Among the 19 patients who were menarche at HSCT, 2 died 6 months post-HSCT and we do not have ovarian function follow-up for the other 2 patients. All the remaining patients (n = 15) had POI. Five patients had OTT. All had a return of ovarian function. One patient gave birth to a healthy baby. CONCLUSION: OTC is a safe fertility preservation technique and could be offered before MAC independent of the patient's age.

BACKGROUND: Ovarian mature teratoma (OMT) is a common ovarian tumor found in the pediatric population. In 10%-20% of cases, OMT occurs as multiple synchronous or metachronous lesions on ipsi- or contralateral ovaries. Ovarian-sparing surgery (OSS) is recommended to preserve fertility, but total oophorectomy (TO) is still performed. DESIGN: This study reviews the clinical data of patients with OMT, and analyzes risk factors for second events. A national retrospective review of girls under 18 years of age with OMTs was performed. Data on clinical features, imaging, laboratory studies, surgical reports, second events and their management were retrieved. RESULTS: Overall, 350 children were included. Eighteen patients (5%) presented with a synchronous bilateral form at diagnosis. Surgery was performed by laparotomy (85%) and laparoscopy (15%). OSS and TO were performed in 59% and 41% of cases, respectively. Perioperative tumor rupture occurred in 23 cases, independently of the surgical approach. Twenty-nine second events occurred (8.3%) in a median time of 30.5 months from diagnosis (ipsilateral: eight cases including one malignant tumor; contralateral: 18 cases; both ovaries: three cases). A large palpable mass, bilateral forms, at diagnosis and perioperative rupture had a statistical impact on the risk of second event, whereas the type of surgery or approach did not. CONCLUSION: This study is a plea in favor of OSS as the first-choice treatment of OMT when possible. Close follow-up during the first 5 years is mandatory considering the risk of 8.3% of second events, especially in cases with risk factors.

OBJECTIVE: SRY-negative 46,XX testicular and ovotesticular disorders/differences of sex development (T/OTDSD) represent a very rare and unique DSD condition where testicular tissue develops in the absence of a Y chromosome. To date, very few studies have described the phenotype, clinical and surgical management and long-term outcomes of these patients. Particularly, early blockade of the gonadotropic axis in patients raised in the female gender to minimize postnatal androgenization has never been reported. DESIGN: Retrospective description of sixteen 46,XX T/OTDSD patients. RESULTS: Sixteen 46,XX SRY-negative T/OTDSD were included. Most (12/16) were diagnosed in the neonatal period. Sex of rearing was male for six patients and female for ten, while the clinical presentation varied, with an external masculinization score from 1 to 10. Five patients raised as girl were successfully treated with GnRH analog to avoid virilization during minipuberty. Ovotestes/testes were found bilaterally for 54% of the patients and unilaterally for the others (with a contralateral ovary). Gonadal surgery preserved appropriate tissue in the majority of cases. Spontaneous puberty occurred in two girls and one boy, while two boys required hormonal induction of puberty. One of the girls conceived spontaneously and had an uneventful pregnancy. DNA analyses (SNP-array, next-generation sequencing and whole-exome sequencing) were performed. A heterozygous frameshit mutation in the NR2F2 gene was identified in one patient. CONCLUSIONS: This study presents a population of patients with 46,XX SRY-negative T/OTDSD. Early blockade of gonadotropic axis appears efficient to reduce and avoid further androgenization in patients raised as girls.

PURPOSE: Transition in urology is defined by the process that allows an adolescent or a young adult with a congenital or acquired urogenital anomaly to assume increasing responsibility for their own health care and to become the primary decision maker in their care. METHODS: A review of the literature regarding transitional care for lifelong urologic congenital anomalies was performed with the aim of reporting expert opinion when data are non-existent. This review focuses on special considerations for adolescents and young adults with spina bifida, bladder exstrophy, anorectal malformations and differences of sexual development. RESULTS: Urologic goals during the transition from childhood to adulthood continue to include attention to the preservation of renal function and optimization of lower urinary tract function. Additional concerns include care to decrease long-term surgical complications (especially after augmentation cystoplasty), to monitor for malignancy, to prepare for sex activity and fertility, and to help the adult patient in decision making. Transition aims to maximize quality of life and independence by ensuring uninterrupted appropriate care through a multidisciplinary approach which varies by geographical location and healthcare setting. Barriers include patient and family factors as well as provider and system related factors. A dedicated team is an important element of successful transition.

PURPOSE: We have studied outcome of double-face preputial island flap (DFPIF) technique in severe types of hypospadias: penoscrotal, scrotal and perineal. METHODS: We have used DFPIF in 75 boys at a median age of 1.1 years (1.0-1.5). The meatus was penoscrotal, scrotal or perineal after de-gloving the penis. The inner face of the foreskin was used for urethroplasty and the outer face for ventral skin covering. Modifications were added: proximal anastomosis was protected by a spongioplasty; in case of urethral plate transection, we anastomosed on onlay proximal and distal segments of the flap (onlay-tube-onlay) and the tubularized part was sutured to corpus cavernosa. FU was scheduled at one month then every 3 months for a year then annually. At each consultation, the surgeon filled out a detailed cosmetic and functional sheet including flowmeter. RESULTS: Thirty-four patients had onlay preputial flap repair with urethral plate preservation. Forty-one had the onlay-tube-onlay technique. All children had a curvature, 19 had a significant residual curvature after dissection, corrected by dorsal plication (n = 9) and ventral lengthening (n = 10). Median FU was 4.2 years (2.7-6.5). 36 children (48%) had complications and needed redo surgery: 12 fistulas, 11 diverticula, 7 meatal stenosis, 3 strictures and 2 residual curvatures. All children but three voided within the normal limits for their age. CONCLUSION: DFPIF remains a good option for a one-stage repair of severe hypospadias. After a median of 1.8 procedures, the final success rate was 96%. The healthy well-vascularized ventral skin allows safe redo surgery when needed.

BACKGROUND: Laparoscopic Nissen fundoplication (LNF) and gastrostomy tube (GT) placement may be performed concomitantly in children with gastro-esophageal reflux disease (GERD) and failure to thrive. We aimed to evaluate the rate and risk factors for LNF failure in children undergoing concomitant LNF/GT. METHODS: A retrospective multi-institutional cohort study was conducted, reviewing patients that underwent LNF (2005-2014). Data collected included patient demographics, comorbidities, and type of GT (laparoscopy- or endoscopy-assisted). The primary outcome measure was LNF failure. Data was compared using contingency tables or Mann-Whitney tests, when appropriate. An exploratory analysis by Kaplan-Meier survival and Cox proportional hazards analysis was performed to determine predictors of time to LNF failure after LNF/GT. RESULTS: Of 189 children that underwent LNF, 99 (52%) had a concomitant GT (55% laparoscopy-, 45% endoscopy-assisted). LNF failed in 15% after LNF/GT and in 17% after LNF alone (p = 0.84), at a median age of 23 months (IQR 8-41). Using univariate analysis, we found that a younger age at the time of surgery (p = 0.05), prematurity (p = 0.0018), esophageal atresia (p = 0.01), and endoscopy-assisted GT (p = 0.02) were potential predictors of LNF failure after LNF/GT. After multivariate regression analysis, prematurity (p = 0.007) remained significantly associated with LNF failure after LNF/GT. No predictive factors for LNF failure after LNF alone were identified. CONCLUSIONS: Concomitant GT insertion and LNF is a common practice, as half of the children that undergo LNF also received GT insertion. Children born preterm or with esophageal atresia comprise a fragile population at high-risk of LNF failure after LNF/GT. Prospective, multicentric studies are needed to evaluate the best GT technique to use in children undergoing LNF.

PURPOSE: XY individuals with disorders/differences of sex development (DSD) are characterized by reduced androgenization caused, in some children, by gonadal dysgenesis or testis regression during fetal development. The genetic etiology for most patients with 46,XY gonadal dysgenesis and for all patients with testicular regression syndrome (TRS) is unknown. METHODS: We performed exome and/or Sanger sequencing in 145 individuals with 46,XY DSD of unknown etiology including gonadal dysgenesis and TRS. RESULTS: Thirteen children carried heterozygous missense pathogenic variants involving the RNA helicase DHX37, which is essential for ribosome biogenesis. Enrichment of rare/novel DHX37 missense variants in 46,XY DSD is highly significant compared with controls (P value = 5.8 × 10-10). Five variants are de novo (P value = 1.5 × 10-5). Twelve variants are clustered in two highly conserved functional domains and were specifically associated with gonadal dysgenesis and TRS. Consistent with a role in early testis development, DHX37 is expressed specifically in somatic cells of the developing human and mouse testis. CONCLUSION: DHX37 pathogenic variants are a new cause of an autosomal dominant form of 46,XY DSD, including gonadal dysgenesis and TRS, showing that these conditions are part of a clinical spectrum. This raises the possibility that some forms of DSD may be a ribosomopathy.

PURPOSE: Human chorionic gonadotropin stimulates fetal testosterone production and contributes to normal development of male genitalia. Using population based data we hypothesized that differences in maternal free beta human chorionic gonadotropin may be associated with hypospadias. MATERIALS AND METHODS: Data were obtained from the Paris Registry of Congenital Malformations (REMAPAR) (2011 to 2016). The initial study population included 3,172 pregnant women who gave birth to a singleton live born male infant with a congenital malformation. After exclusion of cases with unknown beta human chorionic gonadotropin and those with chromosomal or genetic abnormalities, the study population included 194 boys with isolated hypospadias and 1,075 controls. For cases with operative notes (125) we obtained data on type (proximal/distal) of hypospadias. Using quantile regression we compared median values of multiple of median beta human chorionic gonadotropin measured for first trimester Down syndrome screening (10th to 13th gestational weeks) for overall as well as by type of hypospadias vs controls. We also considered possible effects of placental dysfunction (maternal age, intrauterine growth retardation and preterm births) as potential confounding factors. RESULTS: Overall the median beta human chorionic gonadotropin multiple of median was comparable for women who had an infant with hypospadias vs controls (0.99 vs 0.95, p=0.3). However, proximal hypospadias was associated with a statistically significant higher median multiple of median than distal hypospadias or unspecified (1.49 vs 0.92 vs 1.05, p=0.02). The estimates were comparable after adjustment for placental dysfunction. CONCLUSIONS: Our findings support the hypothesis that an alteration in maternal beta human chorionic gonadotropin levels is associated with hypospadias. However, this association appears to be limited to proximal hypospadias.

PURPOSE: Retrocaval ureter (RCU) is a rare congenital anomaly and published data on pediatric laparoscopic management are poor. The aim of this study was to report our experience of retroperitoneal laparoscopic approach for management of RCU in children. METHODS: A retrospective review of data from patients treated for RCU between 2002 and 2018 in our institution was performed. All patients were positioned in a flank position and underwent a three-port (5-mm optical trocar and two 3-mm trocars) laparoscopic retroperitoneal ureteroureterostomy. Anastomosis was made by 6/0 absorbable sutures. A JJ stent was always inserted. RESULTS: Five patients with a median age of 94 months (5-152) were operated on and followed up for a median time of 103 months (46-201). Median operating time was 200 min (160-270). No conversion and no transfusion occurred. Median hospital stay was 2 days (1-4). Ureteral stent was removed after 52 days (47-82). Complications included pyelonephretis (N = 1). In all cases, hydronephrosis decreased postoperatively. CONCLUSIONS: Retroperitoneal laparoscopic approach for RCU is safe and effective in children. Our video demonstrates different patients with specific surgical details to show how to manage these children. The global vision of the upper tract by laparoscopy leads to optimal management of these children even if the anomaly was not detected preoperatively.

PURPOSE: To evaluate the impact of the COVID-19 pandemic-related lockdown on management and outcomes of children with acute appendicitis. METHODS: A retrospective cohort study was conducted, including children treated for acute appendicitis (January 20th-May 11th, 2020). The data regarding the severity of appendicitis and outcome were collected and compared for two time periods, before and after the nationwide lockdown (March 17th, 2020). RESULTS: The number of cases of acute appendicitis increased by 77% during the lockdown (n = 39 vs. n = 69, p = 0.03). During the lockdown, children treated for appendicitis were older (11.1 vs. 8.9 years, p = 0.003), and were more likely to live more than 5 km away from our institution (77% vs. 52%, p = 0.017). Less children had previously consulted a general practitioner (15% vs. 33%, p = 0.028), whereas more children were transferred from other hospitals (52% vs. 31%, p = 0.043). There was no difference in terms of length of hospital stay, rate of postoperative intra-abdominal abscess, ER visits, and readmissions between both periods. Three children (4%) were diagnosed with COVID-19 and appendicitis. CONCLUSIONS: Despite an increase in the number of children with appendicitis managed at our hospital during the COVID-19-related lockdown, management, and outcome remained similar. Although our pediatric center was strongly affected by this pandemic, maintaining our prior practice strategies for acute appendicitis avoided the occurrence of collateral damage for those children.

PURPOSE OF REVIEW: Pediatric testicular tumors have predominantly favorable histology, which may permit testicular sparing surgery (TSS). Limited guidance exists for TSS in adults and is absent in pediatric practice.The international survey and retrospective case series evaluated the current use of TSS in pediatric testicular tumors. Alongside the complementary literature review, the aim of this work was to provide evidence that could be used to produce a guideline document. RECENT FINDINGS: Published evidence advocates small mass size as an indicator for TSS, this was not supported in the pediatric literature. Frozen section examination at TSS was not always performed by surgeons and yet the literature reports close to 100% specificity. Tumor markers and ultrasound findings are also used as indicators for TSS, a finding reflected in our survey results. SUMMARY: Multiple case series are reported but no large data series exists, which will require international collaboration rather than a drive to publish the results of individual centers. Common indicators for TSS use; such as tumor markers and imaging are known but further work needs to evaluate the role of on-table histology and the risks of this not being available.

OBJECTIVE: The objective of the study was to evaluate prenatal sonographic signs that distinguish male fetuses with posterior urethral valves (PUV) from those with vesicoureteral reflux (VUR). METHODS: Prenatal data were retrospectively retrieved from all consecutive women delivering between 2003 and 2012 of a male newborn with a postnatal diagnosis of PUV or VUR. Prenatal parameters included fetal bladder characteristics, identification of a dilated posterior urethra, and change in shape and size in the fetal renal pelvis or ureter. RESULTS: One hundred thirty-six women gave birth to a male newborn with a postnatal diagnosis of PUV (n = 49) or VUR (n = 87). The presence of posterior urethral dilatation [21 (42.9%) fetuses versus 0 (0%), p = 0.000], a thickened fetal bladder wall [37 (75.5%) vs 4 (4.6%), p = 0.000], and anhydramnios [14 (28.6%) vs 0, p = 0.000] were strongly associated with the postnatal diagnosis of PUV. Change in shape and size in the fetal renal pelvis or ureter was observed in 15 (17.2%) of 87 children with VUR versus 1 (2.0%) out of 49 with PUV (p = 0.010). CONCLUSIONS: Prenatal ultrasound may differentiate with reasonable accuracy male fetuses with a postnatal diagnosis of PUV from those with VUR. © 2016 John Wiley & Sons, Ltd.

PURPOSE: There is limited knowledge of long-term bladder function after ureterocele decompression. We studied bladder function in patients who underwent surgery in childhood for duplex system ureteroceles. MATERIALS AND METHODS: Toilet trained children treated for duplex system ureteroceles between 1990 and 2010 were included in study. We evaluated voiding dysfunction by the valid DVSS questionnaire and noninvasive studies, including uroflowmetry, electromyogram and post-void residual urine measurement. Urodynamics were done only in patients with abnormal DVSS or abnormal noninvasive studies. Patients were divided into group 1-ureterocele decompression (endoscopic incision), upper pole partial nephrectomy and ureteropelvic anastomosis, and group 2-primary or secondary bladder surgery (ureterocelectomy, ureterovesical reimplantation and bladder floor reconstruction). RESULTS: Of 62 operated patients 17 were lost to followup and 45 were fully studied at a mean followup of 9.5 years (range 3 to 20). Initial surgery was done at mean age of 5.1 months (range 6 days to 48 months). In the 33 group 1 patients, of whom 70% underwent endoscopic incision, the mean DVSS score was 1.5 (range 0 to 6), 7 patients (22%) had abnormal uroflowmetry or significant post-void residual urine and none had abnormal DVSS results. In the 12 patients in group 2 the mean DVSS score was 4 (range 0 to 11), 8 patients (66%) had abnormal uroflowmetry and significant post-void residual urine, and 3 had abnormal DVSS findings (p = 0.036). All group 2 patients underwent bladder surgery after decompression, including endoscopic incision in 2 and upper pole partial nephrectomy in 1. Only 1 child needed clean intermittent catheterization at age 3 years for hypocontractile megacystis and repeat febrile urinary tract infections. CONCLUSIONS: Ureterocele decompression alone in early childhood does not lead to major bladder dysfunction at long-term evaluation. Even if secondary bladder surgery is needed, significant bladder dysfunction is rare.

Disorders of Sex Development (DSD) are a heterogeneous group of disorders affecting gonad and/or genito-urinary tract development and usually the endocrine-reproductive system. A genetic diagnosis is made in only around 20% of these cases. The genetic causes of 46,XX-SRY negative testicular DSD as well as ovotesticular DSD are poorly defined. Duplications involving a region located â¼600 kb upstream of SOX9, a key gene in testis development, were reported in several cases of 46,XX DSD. Recent studies have narrowed this region down to a 78 kb interval that is duplicated or deleted respectively in 46,XX or 46,XY DSD. We identified three phenotypically normal patients presenting with azoospermia and 46,XX testicular DSD. Two brothers carried a 83.8 kb duplication located â¼600 kb upstream of SOX9 that overlapped with the previously reported rearrangements. This duplication refines the minimal region associated with 46,XX-SRY negative DSD to a 40.7-41.9 kb element located â¼600 kb upstream of SOX9. Predicted enhancer elements and evolutionary-conserved binding sites for proteins known to be involved in testis determination are located within this region.

Anorectal malformations (ARM) are rare congenital anomalies characterized by a spectrum of defects resulting in the absence of a normal anal opening with or without fistula. Urogenital involvement is common, and the fistulous tract may terminate in the genitourinary system in males or within gynecological structures in females. Surgical reconstruction occurs early in life and survival of these patients to adulthood is the norm. There has, therefore, been increased focus on their long-term outcomes to better anticipate and treat the sequelae that may impact their health and well-being as this population ages. For urologists, urinary health, sexual function, and fertility outcomes are of particular interest among this population. This article aims to provide a review of urological, sexual, and fertility outcomes for individuals born with ARM with a focus on key issues that may occur later in life to ensure adequate counseling, screening, and treatment.

INTRODUCTION: Congenital adrenal hyperplasia (CAH) is the most common cause of genital atypia in females. A dedicated multidisciplinary team (MDT) should be included for an optimal management. Here, we aimed to review our surgical experience and to assess long-term urinary, gynecological and endocrine outcomes after primary genitoplasty in this specific cohort. METHODS: Patients born with CAH and who underwent feminizing genitoplasty in our institution were retrospectively identified (2001-2021). We analyzed patients' characteristics, intraoperative details, and postoperative urinary, gynecological, and endocrine outcomes. RESULTS: Forty patients were included and followed-up for a median (IQR) time of 7 (1-19) years. Thirty-eight (95%) had 21-hydroxylase deficiency. After multidisciplinary decision and written consent from patient and/or family, a single-stage reconstructive surgery was performed at a median age of 10 (3-165) months. Median length of hospital stay was 5 (1-7) days. Procedures were: PUM (N = 35 (87.5%)), TUM (N = 3 (7.5%)), urogenital mobilization was unnecessary in 2 (5%). Reduction clitoroplasty was done in 33 (82.5%) patients. Only 3 (7.5%) experienced significant Clavien-Dindo complications requiring additional surgery during the follow-up period. Recurrent urinary tract infections (UTI) occurred in 6 (15%), one required ureteric reimplantation for symptomatic high-grade vesicoureteric reflux. All patients over 3 years were toilet-trained without incontinence. Severe vaginal stenosis occurred in 1 (2.5%) patient. In patients who achieved puberty, 6/9 had vaginal calibration at a median age of 17.3 (16-21) years without detected stenosis. One (2.5%) had major hypertrophy of the right labia minora requiring labiaplasty. Nine (22.5%) reached puberty. Two (5%) patients developed acne/hirsutism. Short stature was noted in 11 (27.5%) and obesity in 18 (45%). CONCLUSION: Based on our contemporary series, genitourinary reconstructive surgery for female patients born with CAH is technically feasible and safe with a low complication rate. A regular follow-up with a MDT to assess long-term complications is necessary, and it is vital to inform patients and families about the different management options with all the risks and benefits of surgery. TYPE OF THE STUDY: original research, clinical research. LEVEL OF EVIDENCE: Level 3 retrospective study.

BACKGROUND: Ureteropelvic junction obstruction (UPJO) is a common congenital urinary tract disorder in children. It can be diagnosed as early as in utero due to the presence of hydronephrosis or later in life due to symptomatic occurrence. AIM: To evaluate the discrepancy between dynamic contrast-enhanced magnetic resonance urography (dMRU) and scintigraphy 99m-technetium mercaptoacetyltriglycine (MAG-3) for the functional evaluation of UPJO. METHODS: Between 2016 and 2020, 126 patients with UPJO underwent surgery at Robert Debré Hospital. Of these, 83 received a prenatal diagnosis, and 43 were diagnosed during childhood. Four of the 126 patients underwent surgery based on the clinical situation and postnatal ultrasound findings without undergoing functional imaging evaluation. Split renal function was evaluated preoperatively using scintigraphy MAG-3 (n = 28), dMRU (n = 53), or both (n = 40). In this study, we included patients who underwent surgery for UPJO and scintigraphy MAG-3 + dMRU but excluded those who underwent only scintigraphy MAG-3 or dMRU. The patients were divided into groups A (< 10% discrepancy) and B (> 10% discrepancy). We examined the discrepancy in split renal function between the two modalities and investigated the possible risk factors. RESULTS: The split renal function between the two kidneys was compared in 40 patients (28 boys and 12 girls) using scintigraphy MAG-3 and dMRU. Differential renal function, as determined using both modalities, showed a difference of < 10% in 31 children and > 10% in 9 children. Calculation of the relative renal function using dMRU revealed an excellent correlation coefficient with renal scintigraphy MAG-3 for both kidneys. CONCLUSION: Our findings demonstrated that dMRU is equivalent to scintigraphy MAG-3 for evaluating split renal function in patients with UPJO.
RESUMO
Purpose: This study aims to evaluate the long-term outcome of the serous-lined extramural continent catheterizable outlet procedure (SLECCOP) associated with ileal bladder augmentation in children. Methods: This was a monocentric and retrospective study (2002-2021) that included children (<18 years) undergoing the SLECCOP associated with W-shaped ileocystoplasty with a catheterizable channel (Abol-Enein and Ghoneim procedure). Patients who received other types of bladder augmentation or W-shaped ileocystoplasty without a catheterizable channel were excluded. Patient records were reviewed for demographic information, surgical data, and long-term outcomes. Results: This study included 52 children [33 boys, median age: 8.5 (0.8-18) years]. Pathological conditions included 28 children with the bladder exstrophy and epispadias complex (BEEC), 11 with neurogenic bladders, and 13 with other pathologies. Two patients underwent total bladder substitution. Thirty-four (65%) patients had bladder neck reconstruction (BNR), with 23 undergoing the SLECCOP and ileocystoplasty and 11 having prior BNR. All stomas, except for two, were umbilical, and were associated with omphaloplasty in 28 patients with the BEEC. A total of 40 stomas were created using the appendix (77%) and 12 with a Monti tube (23%). Stoma-related complications included cutaneous strictures (n = 2, 4%) and leaks (n = 10, 19%), all treated by dextranomer/hyaluronic acid copolymer injection (n = 10). A redo surgery was required in three patients: extraserosal wrapping was performed for persistent leakage (n = 2, 4%), and surgical revision was required for the Monti tube procedure (n = 1, 2%). Three patients (6%) underwent dilatation for transient stoma stenosis. Leakage occurred in 20% of appendix channels (n = 8/40) and 17% of Monti tubes (n = 2/12). Strictures were reported in 3% of appendix channels (n = 1/40) and 8% of Monti tubes (n = 1/12). Bladder stones developed in four patients (8%). Channel leakage persisted in one patient (2%) at a median follow-up of 4.4 years (IQR 1.4-9.7). Conclusion: W-Ileal bladder augmentation with the SLECCOP is an efficient technique for treating children with incontinence caused by different etiologies. The rate of channel complication is very low, specifically for strictures, in this complex population of patients.
RESUMO
BACKGROUND: Staged laparoscopic management of intra-abdominal testes using pedicular section is recognized as gold standard technique, successful in 85 % of cases for scrotal testicular position with less than 10 % testicular atrophy. Recently, Shehata proposed a new technique without pedicular division for these testes, using spermatic vessels traction, but did not provide a comparative study of the two techniques. OBJECTIVE: To evaluate the laparoscopic spermatic pedicular traction (Shehata technique, ST) for the treatment of intra-abdominal testis, as an alternative to gold standard pedicular section (2-stage Fowler-Stephens, FS). STUDY DESIGN: Intra-abdominal testes of 129 patients in two tertiary pediatric urology centers were managed laparoscopically (2011-2019) either by 2-stage FS orchidopexy or ST according to the surgeon preference. Testicular position and size were statistically compared. RESULTS: A total of 147 testes were pulled down by 80 ST and 67 FS, including 18 bilateral cases. Median (IQR) age at surgery was 24.2 (15.6-46.4) months (ST) and 18.3 (13.1-38.2) months (FS) (p = 0.094). Scrotal pulling-down of the testis was performed after a median (IQR) period of 2.3 (1.6-3.4) months (ST) and 6.1 (4.7-8.3) months (FS), respectively (p < 0.005). Although ST had collapsed in 17 cases (21.3 %), only one (1.3 %) redo procedure was required. After a median (IQR) follow-up of 22 (12-40) and 19 (8.75-37) months (p = 0.59), the testis was in the scrotum in 85 % and 81 % of ST and FS cases, respectively (p = 0.51). Testicular atrophy occurred in 10 % of ST and 13.4 % of FS (p = 0.61). Multivariate analysis using the propensity score analysis did not identify any difference between the two techniques. DISCUSSION: Our results seem to confirm that FS and ST achieve the same results regarding final testicular position and testicular atrophy rate, with a long-term follow-up. Our study supports pediatric surgeons to favor laparoscopic spermatic pedicular traction (ST) which preserves the testicular vascularization and may ensure better spermatogenesis after puberty. More details on the size and position of the testicle at the beginning of the first laparoscopy seem however essential to assess more accurately the outcomes of each surgical technique. Our outcomes will also be re-evaluated when our patients have reached puberty, from an exocrine and endocrine points of view. CONCLUSIONS: This study showed similar results after laparoscopic traction or section of spermatic vessels for intra-abdominal testis in a long-term follow-up, providing more evidence for the use of ST as a valuable alternative to FS.
