[Experience in the conservative treatment of renal trauma]. / Experiencia en el tratamiento conservador del traumatismo renal.

OBJECTIVE: The management of renal trauma has been changing in recent years so that nowadays, even in high grades, an initial conservative treatment is advocated. The aim of this work is to review the presentation, initial attitude and evolution of the renal traumas treated in our institution. MATERIAL AND METHODS: Retrospective review of patients with renal trauma treated at our institution in the last 10 years. Epidemiological variables, production mechanism, pediatric trauma index (PTI), treatment and evolution were analyzed. RESULTS: We studied 26 patients, 18 men (69.3%). The most frequent mechanism was the direct hit in 11 patients (42.31%). The most frequently side affected was the right one in 14 patients (53.85%). The grade III traumatism according to American Association for the surgery of Trauma (AAST) was the most repeated, 11 patients (42.31%). Nine patients (44.55%) presented concomitant injuries in other solid organs. In 24 patients (92.30%) the initial treatment was conservative with supportive measures. One patient presented with hemodynamic instability and an urgent intervention was conducted, performing a supraselective embolization with immediate control of the active bleeding. In another patient, a double J catheter was placed due to disruption of the excretory tract. Of the patients treated conservatively initially, only one patient (4.1%) required secondary surgical maneuvers due to a complication. CONCLUSIONS: In patients with renal trauma, non-surgical treatment is safe and effective. In case of hemodynamic instability or complication, interventional radiological techniques have been demonstrated to be safe and effective in the pediatric population.

OBJETIVO: El manejo del traumatismo renal ha ido variando en los últimos años de modo que en la actualidad, incluso en los grados altos, se aboga por un tratamiento inicial conservador. El objetivo de este trabajo es revisar la presentación, actitud inicial y evolución de los traumatismos renales atendidos en nuestra institución. MATERIAL Y METODOS: Revisión retrospectiva de pacientes con traumatismo renal atendidos en los últimos 10 años. Se analizaron las variables epidemiológicas, mecanismo de producción, índice de trauma pediátrico (ITP), tratamiento y evolución. RESULTADOS: Se estudiaron 26 pacientes, 18 varones (69,23%). La causa más frecuente fue el golpe directo en 11 pacientes (42,31%). El lado más frecuentemente afectado fue el derecho en 14 pacientes (53,85%). El traumatismo grado III según la American Association for the Surgery of Trauma (AAST) fue el más común, 11 pacientes (42,31%). Nueve pacientes (44,55%) presentaron lesiones concomitantes en otros órganos sólidos. En 24 pacientes (92,30%) el tratamiento inicial fue conservador con medidas de soporte. Un paciente se presentó con inestabilidad hemodinámica y se intervino de forma urgente realizándose embolización supraselectiva con control inmediato del sangrado activo. En otro paciente se colocó un catéter doble J por disrupción de la vía excretora. De los pacientes tratados de manera conservadora inicialmente solo 1 paciente (4,1%) requirió maniobras quirúrgicas secundarias debido a una complicación. CONCLUSIONES: En pacientes con traumatismo renal el tratamiento no quirúrgico es seguro y eficaz. En caso de inestabilidad hemodinámica o complicación, las técnicas radiológicas intervencionistas han demostrado ser seguras y efectivas en la edad pediátrica.

[Nephroblastoma. Long-term experience in the multidisciplinary approach]. / Nefroblastoma. Experiencia a largo plazo en el abordaje multidisciplinario.

OBJECTIVES: Main objective: to perform a descriptive study of patients with nephroblastoma, diagnostic tests, medical and surgical treatment. Secondary objective: to evaluate the rate of relapse and 5-year survival and risk factors for relapse and death. MATERIALS AND METHODS: Retrospective study of patients with nephroblastoma treated according to the protocol of the SIOP-2001. Demographic variables, comorbidities and associated syndromes were collected. Other data were tumor location, size, extent and stage. The relapse rate and the development of other secondary tumors as well as the long-term survival were also studied. RESULTS: We collected 33 patients with nephroblastoma. A biopsy was performed in 7 patients (21.2%). The Kaplan-Meir curve for event-free survival (tumor recurrence) was 84% with a 95% CI = [0.73-0.98] and the Kaplan-Meier overall survival curve was 0.93 95% CI [0.85-1]. Recurrence occurred in all patients before the first year. CONCLUSIONS: Nephroblastoma is a tumor with a favorable prognosis. The unfavorable histology as well as advanced stages are factors of a poor prognosis. The follow-up must be exhaustive during the first year after the diagnosis.

OBJETIVOS: Objetivo principal: realizar un estudio descriptivo de los pacientes con nefroblastoma, las pruebas diagnósticas, el tratamiento médico y la actitud quirúrgica. Objetivo secundario: valorar la tasa de recidiva y de supervivencia a 5 años y los factores de riesgo para la recidiva y el fallecimiento. MATERIAL Y METODOS: Estudio retrospectivo de pacientes con nefroblastoma tratados según el protocolo de la SIOP-2001. Se recogieron las variables demográficas, comorbilidades y síndromes asociados. Otros datos fueron la localización del tumor, el tamaño, la extensión y el estadio. Se estudió también la tasa de recidiva y/o el desarrollo de otros tumores secundarios así como la supervivencia a largo plazo. RESULTADOS: Se recogieron 33 pacientes con nefroblastoma. En 7 pacientes (21,2%) se realizó una biopsia. La curva de Kaplan-Meir para la supervivencia libre de evento (recidiva tumoral) fue del 84% con un IC 95%= [0,73-0,98] y la curva de Kaplan-Meier de supervivencia global fue de 0,93 IC 95% [0,85-1]. La recidiva se produjo en todos los pacientes antes del primer año. CONCLUSIONES: El nefroblastoma es un tumor con buen pronóstico. La histología desfavorable así como estadios avanzados son factores de mal pronóstico. El seguimiento debe ser exhaustivo durante el primer año tras el diagnóstico.

Urinoma secondary to ureteropelvic junction obstruction in the neonate. Presentation of a case and bibliographic review.

OBJECTIVE: To analyze the management of prenatal urinoma and ureteropelvic junction obstruction (UPJO) postnatally by a case report and literature review. METHODS: We report a case of an UPJO and urinoma in a newborn. After birth, renal function was absent, and nephrectomy was performed. The literature from 1985 to date has been reviewed. DISCUSSION: By the analysis of the literature, we can observe mainly, that prenatally diagnosed urinoma and UPJO are managed conservatively. After birth, different attitudes have been carried out, independently of residual renal function, such as radical or reconstructive surgery, or conservative treatment. CONCLUSION: Intrauterine management is not indicated. Urinary diversion is indicated in symptomatic cases secondary to renal trauma or endoscopic procedure. In non-functional kidney, nephrectomy is indicated.

[Urethral polyposis in adolescence]. / Poliposis ureteral en la adolescencia.

Polyps in the urinary tract are a rare entity in infants and children. The most frequent location when they appear is the ureter. These benign lesions with no malignant potential have a varied form of presentation and in most cases must be distinguished from malignancy. The suspected diagnosis is due to urinary obstruction; nevertheless radiological evidence played a key role in the final diagnosis. The management is as less invasive as possible, with endoscopy resection or minimally invasive surgery.

Analysis of pain perception associated with urodynamic testing in children over 3 years old. / Análisis de la percepción del dolor asociado al estudio urodinámico en niños mayores de tres años.

OBJECTIVE: To measure the tolerance of urodynamic testing (UDT) in the pediatric patient by means of the Visual Analog Scale (VAS). To analyze which clinical and UDT-related variables influence pain perception. MATERIAL AND METHODS: Cross-sectional study of 139 pediatric patients undergoing UDT (December 2013 - May 2018). INCLUSION CRITERIA: understanding and expressing their experience after UDT (preschool and school age). No adolescents were included. Measurement instrument Visual Analog Scale (0-10). Other clinical and UDT-associated variables were obtained. STATISTICAL ANALYSIS: Mann-Whitney U test, Kruskal Wallis test. Spearman's rank correlation analysis (rs). Multivariate analysis through ordinal logistic regression. Significance p < 0.05. RESULTS: Mean age 7.7 years (SD 2.4), median VAS score, 2 (2-6). In 41% (n = 57), the score was ≥ 4 (moderate pain). Multivariate analysis. Explanatory variables for obtaining a high VAS score: high APUDT score (identifying patient anxiety prior to UDT), sensory-motor alteration in the lower limbs, difficult bladder catheterization and the appearance of pain during the filling phase. Age and duration of the UDT have not influenced the VAS score. CONCLUSIONS: Although the UDT has resulted in 40% of the pediatric patients in our study expressing discomfort or pain, it is a well-tolerated test. The variables that have influenced on pain perception were patient's anxiety prior to UDT, a sensory-motor alteration located in the lumbosacral metameres, difficult bladder catheterization and the appearance of pain during bladder filling.

[Congenital fibroepithelial polyps of the urethra]. / Pólipos fibroepiteliales congénitos de uretra.

Urethral polyps are a rare pathology that is usually diagnosed in childhood hematuria and obstructive urinary symptoms are the most common findings and transurethral resection is the best choice of the treatment. We report three cases, a 6-years-old boy and 9-years-old boy diagnosed and treated of posterior urethral polyp after showing hematuria and obstructive urinary symptoms, and a 2-years-old girl that showed to prolapse of urethral polyp.

Spontaneous spermatic vein thrombosis in pediatric patients: A condition to be considered. / Trombosis espontánea de la vena espermática en la edad pediátrica: una entidad a tener en cuenta.

Spermatic vein thrombosis is a very rare pathology, with 25 cases published only, 6 of which in patients under 15 years of age. We present the case of a male patient, as well as a review of the literature. A 12-year old boy presented at emergency with 3-day progressive testicular pain. Following abdominal Doppler ultrasound imaging, he was diagnosed with left spermatic vein thrombosis and nutcracker syndrome. Admission and enoxaparin treatment were decided upon. Patient evolution was satisfactory, with subsequent ultrasound imaging demonstrating the absence of thrombus. The patient is currently under follow-up and without treatment. Various treatments are mentioned in the literature, with conservative management being the treatment of choice.

La trombosis de la vena espermática es una patología muy poco frecuente, con solo 25 casos publicados, 6 de los cuales menores de 15 años. De esta manera presentamos el caso de un varón, así como la revisión de la literatura. Un paciente de 12 años de edad acudió a Urgencias por dolor testicular de aumento progresivo, de 3 días de evolución. Mediante ecografía doppler abdominal se diagnosticó de trombosis de la vena espermática izquierda y síndrome de cascanueces. Se decidió ingreso y tratamiento con enoxaparina. La evolución del paciente fue satisfactoria, en la ecografía posterior se observó la desaparición del trombo. El paciente se encuentra en seguimiento y sin tratamiento. Existen varios tratamientos reflejados en la literatura, siendo el de elección el manejo conservador.

Evaluation of sleep hygiene and prevalence of sleep disorders in patients with monosymptomatic enuresis. Usefulness of the BEARS sleep screening tool. / Evaluación de la higiene del sueño y la prevalencia de sus alteraciones en los pacientes con enuresis monosintomática. Utilidad del cuestionario BEARS.

OBJECTIVES: To analyze if there is a higher prevalence of sleep disturbances and hygiene disorders in patients with monosymptomatic enuresis (MEN) with respect to general population and to patients with corrected MEN. Assess the usefulness of the BEARS sleep disorder screening tool for children with MEN. MATERIAL AND METHODS: Transverse observational study (n=341) classified as: MEN (n=122), corrected MEN (≥ 1 one year without recurrence) (ANTENUR) (n=47) and controls (n=172). The BEARS childhood sleep disorder screening questionnaire was used. Clinical variables were collected, as well as variables related to sleep hygiene. STATISTICS: Chi-square, Student's t, ANOVA, Mann-Whitney U and Kruskal-Wallis. Significance p<.05. RESULTS: Mean age 9.7±3.0 years. There were no statistically significant differences in terms of age, sex, BMI, history of tonsillectomy, asthma and sleep time hours. With respect to sleep hygiene, patients with MEN presented a higher percentage of alterations than controls. As for the BEARS questionnaire, it showed a higher prevalence of sleep disorders in the group of patients with MEN, with respect to the other two groups: 60.7% (n=74) versus 18.6% (n=32) and 38.3% (n=18) of controls and ANTENUR, respectively (p<.05). CONCLUSIONS: Children with MEN had a higher prevalence of sleep disturbances and sleep disorders than controls. The BEARS questionnaire is a useful clinical tool in the detection of sleep disorders in children.

Usefulness of the classification of urinary dysfunction for the prognosis of the first endoscopic treatment of vesicoureteral reflux in children over the age of 3. / Utilidad de la clasificación de los patrones de disfunción miccional en el pronóstico del primer tratamiento endoscópico del reflujo vesicoureteral en niños mayores de 3 años.

OBJECTIVES: To assess the diagnostic performance of urinary dysfunction patterns associated with vesicoureteral reflux (VUR) in children over the age of 3 according to the result of the first endoscopic treatment (ENDT1), grouped into a classification designed by our group (CMD.URI-La Fe). Comparison with other current classifications such as that of Van Batavia et al. MATERIAL AND METHODS: Ambispective cross-cutting study of a sample of 50 children. EXCLUSION CRITERIA: previous ENDT, age ≤ 3 years, anatomical or neurological anomalies and a history of ureteral or abdominopelvic surgery. Prior to the ENDT1, a bladder voiding function assessment by uroflowmetry+electromyography (UF-EMG) and post-mictional residue (ultrasound). Other variables from the bladder diary, pre-mictional bladder wall thickness and other clinical variables. The correction of VUR was assessed by isotope cystography 3 months after the treatment. Urinary patterns were classified according to the significant variables (URI-La Fe), and the diagnostic performance of this classification was assessed, comparing it to the classification of patients as proposed by Van Batavia et al. RESULTS: Mean age: 6.8±2.28 years. Males/females (44%/56%). Grades of VUR (mild/moderate/severe). ENDT1 VUR correction rate: 77% (n=38). Diagnostic performance (Van Batavia; URI-La Fe): correct prediction (37.5%; 75%), sensitivity (32.4%; 87.8%), specificity (54.5%; 46.6%), positive predictive value (70.6; 78.3%) and negative predictive value (19.4%; 63.6%). CONCLUSIONS: Our results show the usefulness of the non-invasive test and the classification of urinary dysfunction in children aged over 3 years prior to the first endoscopic treatment of VUR.

[Intratesticular calcifications in childhood]. / Calcificaciones intratesticulares en la edad pediátrica.

INTRODUCTION: Testicular microlithiasis (TM) represents an uncommon occurrence at paediatrics with a radiological incidence between 0.16 to 0.6% according to reports. The greater use of ultrasound as well as the availability of high-frequency probes has increased the number of incidental TM being diagnosed. MATERIAL AND METHOD: From January 1998 to October 2002 seven children, aged 9 to 13 years (average 11 years and 1 months), were diagnosed of MT in our department. Sonographic appearance was hyperechogenic multiple small foci of 1-3 mm without acoustic shadowing of the testicular parenchyma. AIM: To evaluate sonographic patterns of TM, their associations, clinical consequences and to determine their management. RESULTS: All children were asymptomatic and the reasons for the ultrasound were: cryptorchism (3), short height (1), gynecomastia (1), varicocele (1) and scrotum trauma (1). It should be noted that 3 of the cases showed bilateral TM. Out of 10 testicles with TM, 8 met classic testicular microlithiasis (CTM) criteria (at least one image that showed five or more microliths in either or both testes) and 2 had limited testicular microlithiasis (LTM) (to have at least one microlith). Clinical and radiological follow-up is being performed annually, ranging from 18 months to 6 years, during which there hasn't been progression or regression in the number of TM or in their distribution. In none of these cases there has been shown a related testicular cancer. CONCLUSIONS: In other broad reviews it has been shown that there is no evidence to suggest that the TM have to be considered as premalignant lesions by themselves. However, the association among TM and cancer exists. Because of that, and due to the lack of consensus, we recommend annual clinical and radiological (ultrasound) follow-up until puberty, and thereafter the patient should be informed of unknown natural history of this condition. We do not recommend more invasive procedures such as biopsy except: 1) apart form the TM there is a change in the echogenicity or 2) if there is a change in the number or distribution of the TM.

[Torsion of undescended testis]. / Torsión testicular en testes no descendidos.

Torsion of a cryptorchidid testicle presents a non-specific symptomatology. Clinical suspicion indicates surgical exploration, irrespective of Doppler ultrasound with its inherent false negative results. With regards to treatment, an orchiectomy is performed when the testis is necrotic. Management of the contralateral testis is controversial. Our policy is not to fix them systematically because we believe that a healthy education of parents and children is more important, so as to obtain an earlier diagnosis of a future torsion.

[Parameatal urethral cysts. 3 new paediatric cases and literature review]. / Quistes uretrales parameatales. 3 nuevos casos pediátricos y revisión de la literatura.

We present 3 new cases of urethral parameatal cysts in paediatric age. Literature is reviewed and histological data and ambulatory management are discussed.

[Assesmment urethrorrhagia in childhood]. / Valoración de la uretrorragia en el niño.

OBJECTIVE: [corrected] To review urethrorrhagia cases, the need of complementary test, its management and natural history. MATERIAL AND METHOD: A retrospective analysis was carried out for the 12 patients who suffered from urethrorrhagia, consecutively diagnosed in our department. Parameters as age, and micturitional habit were evaluated. In this way, we described the diagnostic techniques used, assessment and the follow-up of each patient. RESULTS: All cases correspond to male children with an average age of 8.7 years (range: 18 months-14 years). Urethrorrhagia appears in 100% of the patients, episodes which were daily in 58.4%. 33% (4/12) of them also present other micturitional symptoms. 75% (9/12) had a lazy micturitional habit. Among the urological backgrounds we found: 1 patient was circumcised 3 years ago, a meatotomy was done in other due to meatus stenosis 2 years before, and a last one had an electrocoagulation of a urethral polyp just 1 month before. 83.4% (10/12) of urine cultures were negative. An urethrocystoscope was done in 9 patients finding a verum hypertrophy in 4, inflammatory changes next to membranous urethra in 3, scar at the bulbar urethra in 1 and in a last one no abnormalities were found. Out of 8 patients with lazy micturitional habit, 75% (6/8) resolve spontaneously once they correct their habits after a mean follow-up of 9 months. Only 2 patients needed surgery (TUR). In the other 2 patient, symptoms. CONCLUSIONS: Urethrorrhagia in childhood is a benign condition in most cases, which is almost always cured spontaneously during the first 2 years of follow-up. Radiological studies as well as endoscopic procedures are unnecessary in the early management of these patients thus being relegated to recurrent or persistent bleeding.

[Hypospadias repair with Snodgrass' technique]. / Reparación de hipospadias mediante la Técnica de Snodgrass.

Retrospective study of 124 patients (average age: 3.8 years) with midpenile hypospadias: 48.3% (60 children), distal penile: 45.9% (57) and coronal 5.6% (7), of which the 25.8% (16) presented ventral curvature and the 4.8% (6) resulting from the complication of another previous technique. All of them were operated according to Snodgrass' technique, removing the catheter between the 6th and 7th day in most of them. The global rate of complications was of 12%: 9 fistulae (7.2%) and 6 meatal stenosis (4.8%). Aesthetic result was satisfactory in all cases, getting glans covered by foreskin in 57.3%.

Multicystic dysplastic kidney: Assessment of the need for renal scintigraphy and the safety of conservative treatment. / Displasia renal multiquística: evaluación de la necesidad de la gammagrafía renal y seguridad del tratamiento conservador.

OBJECTIVES: To assess the need for implementing renal scintigraphy in the diagnosis of the multicystic dysplastic kidney (MCDK) and the safety of its conservative treatment. MATERIAL AND METHODS: A retrospective study of patients with unilateral MCDK was conducted at our centre from January 2005 to August 2015. We calculated the positive predictive value (PPV) of ultrasonography, taking renal scintigraphy and pathology as the gold standard. We calculated a survival curve according to the Kaplan-Meier method to assess the annual probability of spontaneous resolution of the multicystic kidney. RESULTS: Fifty-six patients were identified, 48 (85.7%) of whom had a prenatal diagnosis. Thirty eight (67.9%) of the patients were males, and the left side was affected in 33 (58.9%) of the patients. We observed associated urological abnormalities in 22 (39.29%) patients, with vesicoureteral reflux the most common (8, 14.29%). Seven patients (12.5%) developed renal failure. Forty-nine (87.5%) patients developed compensatory contralateral renal hypertrophy. Of the 33 patients who underwent surgery, the pathology results confirmed the MCDK diagnosis in 32. Compared with scintigraphy and pathology, the PPV of ultrasonography was 100% and 97%, respectively. The rate of spontaneous involution was 5.4% at 3 months of life, 11.3% at 2 years and 38.4% at 5 years. CONCLUSIONS: In our experience, the conservative treatment of MCDK, until at least 5 years of age, is safe. Our data suggest that performing scintigraphy is not required for these patients, which means lower radiation exposure, as well as financial savings.

[Ultrasound role in assessment of vesicoureteral reflux endoscopic treatment results]. / Papel de la ecografía en la valoración del resultado del tratamiento endoscópico del RVU.

INTRODUCTION: Since the beginning of the application of the RVU treatment, the use of the ultrasound was used taking into account two main indications/symptoms: a) identification of the complications; b) assessment of the result (visualization of the implanted material and the presence of the "uretheral jet" by means or through/of ecodoppler-color). OBJECTIVE: To determine the value of the ultrasound in the assessment of the result of the endoscopic treatment of the RVU and in the detection of its complications. MATERIAL AND METHOD: From 2001-2002 we have carried out the endoscopic treatment to an overall of 261 ureteral units of all degree and etiology. 246 were assessed post-operation with an ultrasound per month and all of them were evaluated with a cistography after 3 months. In a random sample of 92 units, the result of the isotopic cistography has been compared with the visualization of the implanted material in the bladder; and in a random sample of 56 units, the result of the isotopic cistography has been compared with the presence of ureteral jet in the study with ecodoppler-color after moisturizing of the patient. In order to do, we have done two corresponding comparative charts 2 x 2 and we have calculated the Sensibility and Specificity of the tests, as well as their predictive positive and negative values, the degree of similarity of both tests with the Kappa index, and the degree of statistical relevance with Chi squared. RESULTS: The ultrasound did not show significant changes if compared to previous studies in 213 units (86,58 %) although in 5 patients an ectasia has been identified as attributed to the treatment. 3 of this patients have developed renoureteral pain, and in 2 pain has spontaneously disappeared as shown in later tests. The S and the E of the presence of implanted material is 94% and 10%respectively and its VPP and VPN of 80% and 10% and estadistical. The S and E of the jet visualization is 82% and 30%, with a VPP of 84% and a VPN of 27%, a level of statistical relevance of 0.836 and a degree of correlation of 0.121. CONCLUSIONS: Ultrasound is not a useful technique in the assessment of the result of the endoscopic treatment of the RVU. The role it plays in the assessment of complications is a small one and its use is only indicated to confirm the suspicion of ectasia in those patients that present renoureteral pain.

[Efficacy in endoscopic treatment of secondary vesicoureteral reflux with polydimethylsiloxane]. / Eficacia a largo plazo del tratamiento endoscópico en el reflujo vesicoureteral de etiología secundaria con polidimetilsiloxano.

OBJECTIVE: To value the efficacy in endoscopic treatment of the vesicoureteral reflux (VUR). MATERIAL AND METHOD: We have realized a prospective study in patients with RVU treated with endoscopic polydimethylsiloxane, from January 1999 until December 2001, analyzing the results after an average pursuit of 30 months. We included 144 patients, 92 girls and 52 children, with 213 VUR (124 primary ones and 89 of secondary etiology). The initial efficacy of the treatment was defined as the finished absence of RVU in the isotopic cystography, realized three months after the puncture. RESULTS: The global efficacy of the endoscopic treatment in secondary etiology reflux was lower than the reached one in the treatment of the primary RVU (77.7% against 86.2%) but the differences did not reach statistical significance (p=0,226). We do not also find significant differences on having compared the injected volume and the valuation of resolution of the ebb between the different causes of secondary RVU (p=0.361). We found recurrence in patients with RVU due to lower urinary tract dysfunction (4.34%). CONCLUSIONS: Endoscopic treatment of the secondary VUR is a minimally invasive skill, presents scarce morbidity and it is effective in chosen patients. The risk of a long term recurrence is grater in VUR secondary to functional alterations (neurogenic bladder and functional instability), for what, pursuit has to be established according to the base pathology.

[Infected urachal cyst during childhood]. / Quiste de uraco infectado en edad infantil.

Urachal cysts are congenital anomalies detected predominantly during the childhood. They are often diagnosed when an infection occur mimicking a variety of acute intra-abdominal or pelvic processes. We present a case in a 7-year-old female infant, diagnosed of infected urachal cyst. The embryologic origin of this anomaly, clinical features, diagnosis and treatment are discussed.

[Congenital megaprepuce: diagnosis and terapeutic management]. / Megaprepucio congénito: diagnóstico y manejo terapéutico.

OBJECTIVE: [corrected] To analize the clinical presentation, diagnosis and surgical management of congenital megaprepuce (CM). MATERIAL AND METHODS: We have made a retrospective study of four cases of CM diagnosed and treated in our centre between october 1997 and april 2005. We studied the diagnosis and surgical treatment. CONCLUSIONS: CM is an infrecuent condition that can be confused with others pathologies. It's necessary to diagnose and treat it correctly.

[Vesicoureteric reflux endoscopic treatment complications in childhood]. / Complicaciones del tratamiento endoscópico del reflujo vesicoureteral en la infancia.

INTRODUCTION: Nowadays, around 1% of children suffer from vesicoureteral reflux (VUR), which represents a risk factor for long-term kidney damage. In the last decade, development in this field has shown that subureteric endoscopic injection of bulking agents for childhood VUR is an acceptable alternative unlike long-term antibiotic prophylaxis and open surgery. OBJECTIVE: To establish the complications of childhood VUR endoscopic treatment. MATERIAL AND METHODS: A retrospective analysis was carried out for every patient treated endoscopically in our department from January 1999 to September 2003, with a total amount of 516 implants of submucous bulking agents. All patients were assessed with an ultrasound as a first diagnostic technique so as to establish the complications associated with it, especially ureteral obstruction and injected agent migration. RESULTS: Out of 516 cases, Macroplastique was used in 455, Deflux in 44 and Polytef in 17. 10 patients (1.9%) (5 girls/ 5 boys), with ages ranging from 15 months to 11,4 years, presented some kind of complications (Macroplastique was used in 8cases and Deflux in 2). Among them, 5 were remarkable due to an ureterohydronefrosis, 2 of which needed a nephrostomy. 3 patients presented an implant migration, 1 epididymitis and 1 bladder edema. CONCLUSIONS: Endoscopic bulking agent injection has become a safe alternative to open surgery in childhood VUR management.
