[Vesicoureteric reflux endoscopic treatment complications in childhood].

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.

[Ultrasound role in assessment of vesicoureteral reflux endoscopic treatment results].

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.

[Pyeloureteral duplicity and intrathoracic kidney].

Intrathoracic ectopia is an unusual ectopia that represents less than 5% of renal ectopia. The association of a duplex system and an intrathoracic renal ectopia is very rare. We report a case of a girl affected from these two anormalities, being the first case published in the literature reviewed. Presentation, diagnosis and therapeutic aspects are discussed.

[Vesicostomy in children. Our experience with 43 patients].

INTRODUCTION AND OBJECTIVES: Cutaneous vesicostomy (CV) is a choice temporary urinary diversion technique for patients with upper urinary tract (URT) dilation, secondary to vesical o infravesical disease. The objective of this study is to share our experience in children undergoing such diversion, analysing its efficacy to prevent urinary infections, improve or resolve the ureterectasia, and stabilise or improve renal function; in short the functional and morphological recovery of URT. MATERIAL AND METHODS: 43 children, mean age 2.5 years (range: 1 month-14 years) with ureterohydronephrosis grade IV-V, persistent urinary infection and/or renal function impairment underwent cutaneous vesicostomy (Blocksom's technique in 36 and Lapides' procedure in the rest). Thirty subjects had neuropathic bladder (26 with secondary vesicoureteral reflux), 7 massive primary vesicoureteral reflux, and 6 posterior urethral valve. RESULTS: All children (100%) with neurogenic bladder (30 cases), showed improvement of ureteral-pyelic-calyceal ectasia after the diversion, and 90% improved renal function with disappearance of vesiculoureteral reflux in 65%. Augmentation cystoplasty with gut was performed in 12 patients during vesicostomy closure, using Mitrofanoff's type diversion in 5 of them. The same continent diversion with cecal appendix was used in another 7 children as the only procedure. The remaining 11 children still retain their vesicostomy. In 5 of the 7 children with primary vesicoureteral reflux, the reflux disappeared and so the vesicostomy was closed. Reflux correction during the same surgical procedure was required for the other 2 children. Of the 6 children with posterior urethral valves, 2 received a renal transplant, one is in waiting list and the rest (50%) maintain an acceptable renal function. In the first year of follow-up, 4 patients developed symptomatic urinary infection that later disappeared. The rest had occasional asymptomatic bacteriuria that required no treatment. Complications included vesical prolapse due to ostomy in 4 patients, lithiasis in 3 and stomal stenosis in 2. CONCLUSIONS: We consider vesicostomy to be the choice urinary diversion technique in cases of common section obstruction and/or non-obstructive ureterohydronephrosis in new-borns who do not improve with conservative treatment.

[Bilateral testicular epidermoid cyst in a pediatric patient with Klinefelter syndrome].

Epidermoid cysts of the testis are rare in children (3% of all the testicular tumors). Bilateral appearance has only been described in the pediatric age in 2 cases and none associated to Klinefelter's syndrome. We present, for our knowledge, the first case of bilateral epidermoid testicular cyst associated to klinefelter's syndrome in a boy, highlighting its management and therapeutic approach. We analyze the different kinds of treatment.

[Diagnostic attitude in a patient with kidney trauma].

OBJECTIVE: Our aim was to assess our results in the management of renal trauma patients. PATIENTS AND METHODS: A retrospective review of medical charts from 1989 to 1997 was carried out. RESULTS: Twenty-seven cases involving 27 kidneys were treated during the study period, with 16 grade II injuries, 8 grade II and 3 grade III. Ultrasound was the most used diagnostic tool, followed by computerized tomography (CT) and intravenous pyelography (IVP). Falls and traffic accidents were the main etiologic agents (48 and 41%, respectively). Eight out of 11 patients with grade II/III injuries received surgical treatment. Three cases required early surgery immediately after arrival and 5 cases had planned surgery. After a mean follow-up period of 16 months, renal function has remained above 40% in all patients, excluding 3 cases treated with partial nephrectomy. CONCLUSIONS: A conservative attitude is of choice in children with renal trauma. CT is the main diagnostic tool except in patients suspected of isolated grade I injury. Ultrasound followed by IVP is a valid choice for these cases and especially helpful for preschool patients which require general anesthesia for CT exploration.

[Latex allergy in children with myelomeningocele. Incidence and associated factors].

RATIONALE: The purpose of our work is to know the prevalence of allergies to latex in patients with myelomeningocele (MMC) and to evaluate any potential factors influencing its development. METHODS: The study included 100 children with mean age 7.5 +/- 4.8 years, diagnosed with MMC by skin tests and total and latex-specific IgE determination. The results were compared to those obtained in three "control" groups: atopic patients, patients undergoing their first operation and multi-operated patients. The relationship between the different variables analyzed was assessed using univariant and multivariant statistical studies. RESULTS: 29 were sensitized (15 symptomatic and 14 asymptomatic) and 8 doubtful. Results showed statistically significant (p < 0.05) differences for atopic and first operation groups and non significant differences for the multi-operation group. The multivariant study selected the followed as the most relevant variables: number of surgical interventions, total IgE levels in z units, ventricle-peritoneal by-pass carriers and atopy background. Also in the multivariant study, the following showed statistically significant results: age, Cums' number, inclusion in intermittent catheterism program and total IgE levels. Neither sex or familial background of atopy showed statistical significance. CONCLUSIONS: Allergy to latex in MMC patients is related to multiple antigen contacts, the numerous manipulations and operations undertaken throughout the patient's life plus a personal propensity to allergies. It is essential that this group should adopt certain standards to minimize contact with the antigen and undergo an allergological study so as to detect those who are sensitized, which in nearly half our series has not yet exhibited symptomatology in contact with latex utensils. All diagnostic and therapeutical procedures should be conducted in latex-free environments.

[Tumor of the testicular vitelline sac in children: clinical course and treatment].

Presentation of a review of 10 paediatric patients with tumour of the testis vitelline sack, to report our experience in the management of this pathology. Mean age was 20 months (14-32), and the interval of the study was from 1970 to 1994. After orchiectomy, 7 children were included in stage I, 1 in stage II, and 2 in stage III. Four underwent Retroperitoneal Lymphadenectomy. All patients in stage I are currently free of disease, with a mean follow-up of 132 months, regardless the type of treatment employed (vigilance in 2 cases, chemotherapy in 2, and chemotherapy plus Retroperitoneal Lymphadenectomy in 3). On the contrary, the 3 children with extratesticular disease died 15, 18 and 15 months after orchiectomy. In conclusion, we believe that patients included in stage I should undergo only a strict vigilance, based on the excellent prognosis of this group and the lack of differences between the survival time obtained with the various therapeutical approaches followed. On the other hand, patients with stage II or stage III disease should receive from the beginning chemotherapy, thus saving the Retroperitoneal Lymphadenectomy for the residual disease.

[Vesicostomy in children].

OBJECTIVES: To evaluate the upper urinary tract morphology and function in children undergoing vesicostomy for different causes. METHODS: We report on 27 children aged 1 month to 12 years who had undergone a Blocksom vesicostomy procedure. Twenty had a neuropathic bladder and 3 had posterior urethral valves. RESULTS: In the 20 children with neuropathic bladder, renal function improved in 95% and the associated vesicoureteral reflux improved in 56%. The morphology of the upper urinary tract returned to normal prior to the definitive operation in all cases. Only one of the patients with posterior urethral valves has preserved satisfactory renal function two years following vesicostomy. The most common complication was prolapse (14.8%). CONCLUSIONS: In our view, vesicostomy is the best urinary diversion procedure in the cases described herein. Vesicostomy closure must be performed following definitive treatment of the underlying condition, except in those cases with neuropathic bladder who require augmentation cystoplasty to keep upper urinary tract pressures low.

[Paratesticular rhabdomyosarcoma in children. Is retroperitoneal lymphadenectomy necessary in disease limited to the scrotum?].

Between 1970 and 1993, five children with paratesticular rhabdomyosarcoma (PR) and age ranging from 3 to 10 years were treated by our group. Following radical orchidectomy and clinical staging, 4 were rates as Group I-IRS (completely resected local disease) and 1 in Group IV-IRS (distant metastasis). All patients in Group I underwent intensive chemotherapy with vincristine, actynomicin D and cyclophosphamide (VAC) for 18 months, while no case of retroperitoneal lymphadenectomy was performed. Currently, all patients are disease free with a mean follow-up of 8 years and 5 months. The single patient included in Group IV received radiotherapy (800 rads in abdominal field) and chemotherapy with VAC + prednisone (PDR), and retroperitoneal lymphadenectomy of residual masses was performed. The patient developed liver metastasis and died 20 months later. The purpose of this paper is to convey the reader our experience in the treatment of PR in children, making a special reference to the excellent prognosis when the disease is limited to the scrotum and recommending in such cases the use of intensive chemotherapy with VAC after performing radical orchidectomy.

[Renal sarcoma].

Among 322 cases of primary malignant renal tumours reviewed between 1969 and 1991, six were renal sarcoma (1.85%). They all presented earlier symptomatology which was not different from other renal tumours, and nephrectomy was performed in all cases, 5 of which died before 14 months. The histopathological diagnose showed two liposarcoma, two carcinosarcomas, all the others being fibrosarcomas.

[Pyeloureteral junction syndrome. Associated vesicoureteral reflux].

We reviewed our series comprised of 106 children that had undergone surgery for congenital hydronephrosis from ureteropelvic junction obstruction. Following our protocol, all patients were evaluated by serial micturition cystourethrography. The only anomaly that had been detected was vesicoureteral reflux in 11.32% of the cases. This incidence is reduced to 8.25% if only the renoureteral systems with both congenital anomalies are considered. This finding is not statistically significant (p less than 0.05) relative to patient age, sex or clinical symptoms. The results of the present study show that children with ureteropelvic junction obstruction are not at risk of developing vesicoureteral reflux. Thus, routine serial micturition cystourethrography appears to be unwarranted.

[Valves of the anterior urethra].

Despite the cases reported in the literature, anterior urethral valves continue to be an uncommon condition. The foregoing has to be considered when evaluating children with urinary obstruction or recurrent infections. A case of anterior urethral valves associated with segmental saccular dilatation of the urethra is described and the diagnostic methods are highlighted.
