RESUMO
Assessment of morphometric and volumetric changes in lacrimal glands in thyroid eye disease, its clinical manifestations in relation of disease progression. Retrospective volumetric analysis included both genders and was performed on total of 183 patients - 91 patients with diagnosed Grave's disease and thyroid eye disease and 92 patients without Grave's disease and thyroid eye disease who underwent multidetector computed tomography (MDCT) examination in routine daily work according to other medical indications. In the group of females, there was statistical significance between patients with thyroid eye disease and controls who were smoking and had body weight gain. We found statistical significance in volumetric enlargements for both orbits in both genders for the patients group when compared to controls. There was also statistical significance in morphometric characteristics for the lacrimal gland diameters measured. Determination planimetric morphometric parameters of importance were coronary height of lacrimal gland of the right eye, coronary height of lacrimal gland of the left eye and coronary width of lacrimal gland of the left eye for the group of males. In a group of females the established determination parameters of importance were the coronary height of lacrimal gland of the left eye, the axial width of lacrimal gland of the left eye, volume of lacrimal gland of the right eye and the volume of lacrimal gland of the left eye. When we compared the displaced lacrimal gland coming forward (proptosis) in time progressing disease between group of patients and controls, we also found statistical significant connection. Evaluation of lacrimal gland volumetric and morphometric data may increase validity of defining this anatomical substrate and its morphology disruption as liable tool for thyroid eye disease progression follow up and treatment planning and outcome.

Background: The aim of this study was to examine the correlation between the transverse rectal diameter and urodynamic findings in children with neurogenic bowel and bladder dysfunction. Methods: Between 2014 and 2022, we prospectively evaluated 81 consecutive spina bifida children with neurogenic bowel and bladder dysfunction (35 boys and 46 girls, mean age 9.5 ± 3.4 years). All patients underwent echosonographic measurement of transverse rectal diameter and urodynamic studies. Results: We found a strong negative correlation between transverse rectal diameter and maximum bladder capacity (r = -0.682, p < 0.001) and compliance (r = -0.690, p < 0.001). There was also a strong positive correlation between transverse rectal diameter and maximal detrusor pressure (r = 0.650, p < 0.001), leak point pressure (r = 0.793, p < 0.001), and PVR (r = 0.762, p < 0.001). In ROC analysis, transverse rectal diameter demonstrated good performance for distinguishing children with upper urinary tract deterioration, with an AUC of 0.857 (95% CI 0.761-0.953). A transverse rectal diameter ≥40 mm was 83.3% sensitive and 100% specific for the diagnosis of unfavorable urodynamic patterns. Conclusion: There is a correlation between the transverse rectal diameter and urodynamic findings in children with neurogenic bowel and bladder dysfunction. Ultrasonographically assessed transverse rectal diameter of ≥40 mm may be used as a risk factor for upper urinary tract deterioration (unfavorable urodynamic findings). We suggest the transverse rectal diameter echosonographic measurement use as an integral part of the diagnostic approach in children with neurogenic bowel and bladder dysfunction, as it can help decision-making while waiting for urodynamic testing.
RESUMO
INTRODUCTION: To examine the reduction of transverse rectal diameter and its effect on bladder dynamics in children with spinal dysraphism. METHODS: We prospectively evaluated 61 consecutive children with spinal dysraphism, 25 (41%) boys and 36 (59%) girls, aged 4 to 16 years; mean age 9.3 ± 3.8 years, who received bowel management. All children underwent echosonographic measurement of transverse rectal diameter before and after starting bowel management. Also, all the patients had undergone urodynamic studies before and after starting bowel management, with no changes in their urological treatment. RESULTS: Bowel management caused an decrease in transverse rectal diameter by 56 ± 7.2% (p < 0.001). In addition, a decrease was observed for maximal detrusor pressure by 27.8 ± 7.8% (p < 0.001), leak point pressure by 37.2 ± 4.4% (p < 0.001), and PVR by 36.7 ± 8.0 (p < 0.001). Maximum bladder capacity was significantly increased after bowel management in both non-adjusted (36.4 ± 14.8%; p < 0.001) and adjusted analysis for age (39.4 ± 14.3%, p < 0.001). Detrusor compliance was also increased by 89.2 ± 24.8% (p < 0.001). Female gender and % change of maximal detrusor pressure were significant predictors of transversal rectal diameter change in univariate as well as in multivariate analysis (OR = 10.548, 95% CI 2.309-48.180; p = 0.002 and OR = 1.121, 95% CI 1.009-1.245; p = 0.034). CONCLUSIONS: Decrease in transverse rectal diameter may be useful for bladder function and urodynamic findings in children with spinal dysraphism. Therefore, decrease in transverse rectal diameter should be a supplement to standard urotherapy.

BACKGROUND: Anterior mitral leaflet prolapse repair is a highly effective procedure, but despite excellent operative results still has an inferior long-term durability when compared to posterior leaflet repair. METHODS: We analysed mitral repair durability in 74 consecutive patients operated for anterior leaflet prolapse between 2010 and 2021. Their pre- and postoperative clinical, echocardiographic data and repair durability as well, were compared with 74 randomly assigned posterior leaflet prolapse patients who underwent valve repair during the same period. RESULTS: While groups were of similar age, patients with anterior leaflet prolapse had an inferior preoperative status in terms of functional reserve, atrial fibrillation, operative risk, ejection fraction and had more dilated left heart chambers as well. 1, 5, and 10-year freedom from repair failure was 87.1 ± 4.6%, 79.8 ± 6.5% and 50.7 ± 12.5% in the anterior, and 98.5 ± 1.5% respectively in the posterior leaflet group. Atrial fibrilation (hazard ratio [HR] 5.365; 95%; confidence interval [CI] 1.093-26.324 p = .038) and left ventricle end-systolic diameter (HR 1.160 95%; CI 1.037-1.299 p = .010) independently predicted anterior leaflet repair failure. Receiver Operating Curve analysis established left ventricle end-systolic diameter ≤42 mm as a cut-off value associated with improved anterior leaflet repair durability. Accordingly, 10-year repair durability in a subset of patients, with preserved left ventricle end-systolic diameter (≤42 mm) was 86.4 ± 7.8%. CONCLUSION: Better long-term repair durability in patients with anterior mitral leaflet prolapse and preserved sinus rhytm and left-ventricle diameters justifies early reconstructive approach.

AIMS: To evaluate the impact of compliance on the therapeutic effects of Desmopressin, as well as the importance of establishing the voiding school for low-compliance children in primary monosymptomatic enuresis treatment. METHODS: Eighty-nine patients with primary monosymptomatic enuresis treated with Desmopressin were observed during the 2017-2020 at University Children's Hospital Belgrade, Serbia. The average patients age was 7.7 ± 2.4 years; 65 (73%) were boys and 24 (27%) % were girls. After the 3 months of Desmopressin treatment, the effect of therapy was evaluated according to the compliance. After the treatment, low-compliance patients and their parents were suggested to visit a voiding school. RESULTS: A significant decrease in the median enuresis frequency was noticed during the Desmopressin treatment (25.0 (20.0-26.0) vs 10.0 (2.0-17.0) per month, before vs after treatment, respectively) (p < 0.001). Patients with low compliance had a poorer response to Desmopressin (p < 0.001). An median enuresis reduction in the good compliance group was 92.3% (86.7 -95%), while in the low compliance group was 28.6% (16.7-43.3%). After attending voiding school, there was a significant increase in compliance (p < 0.001), associated with an median percent decrease in enuresis of 84.0% (75.0-95.5%) (p < 0.001). CONCLUSION: Compliance considerably influences the beneficial effects of Desmopressin. Patients with poor therapeutic effects should be evaluated for compliance and introduced to voiding school.

PURPOSE: To test the therapeutic effects of Desmopressin (dDAVP) in primary monosymptomatic nocturnal enuresis (PMNE) treatment depending on patients'age. MATERIAL AND METHODS: The prospective research was carried out in the 2014-2018 period, during which 89 patients were observed who were treated with dDAVP due to the previously diagnosed PMNE. The patients were divided into two age groups. The first group (Group 1) consisted of 43 patients age 5 to 6, with the average age of 5.6 ± 0.5, out of whom 35 (81.4%) were boys, and 8 (18.6%) girls. The second group (Group 2) consisted of 46 patients age over 7 to 12, with the average age of 9.7 ± 1.6, out of whom 30 (65.2%) were boys, and 16 (34.8%) were girls. There was no statistically relevant difference according to sex (p = 0.086). After the 3-month treatment, all the patients in both groups were tested for the effects of dDAVP in PMNE treatment. RESULTS: The average enuresis frequency in the first group (Group 1) before therapy was 26.0 ± 6.2 per month, whereas the average enuresis frequency after therapy was 11.0 ± 8.0 per month (p = 0.040). The average enuresis frequency in the second group (Group 2) before therapy was 23.1 ± 6.2 per month, whereas the average enuresis frequency after therapy was 3.8 ± 3.6 per month (p = 0.036). ANOVA data analysis of repeated measurements has indicated that there is a statistically relevant interaction between the groups (p = 0.006), i.e. enuresis frequency decreases considerably more in the second group (Group 2). CONCLUSION: PMNE with dDAVP is noticeably more effective with patients over 7 years of age.

OBJECTIVE: To examine the effects of bowel management on urodynamic findings in spina bifida children with detrusor overactivity (DO) and detrusor sphincter dyssynergia (DSD). MATERIAL AND METHODS: Between 2014 and 2019 we prospectively evaluated 39 consecutive spina bifida children with DO and DSD (18 (46.2%) boys and 21 (53.8%) girls, aged 4-16 years; mean age 9.5 ± 3.7 years) who received bowel management and we treated their bowel dysfunction with an aim of alleviating the symptoms of constipation, preventing constant overdistension of the rectosigmoid, providing regular emptying of the colon and faecal continence. Bowel management included daily enema, laxative application and a special diet who was performed during 12 months. All children had undergone urodynamic studies before and after starting bowel management, with no changes in their urological treatment. RESULTS: Bowel management caused an increase in maximum bladder capacity from 183.0 (112.0-234.0) to 237.0 (165.0-298.0) (p < 0.001). When maximal bladder capacity adjusted for age there was also significant increment (adjusted before 0.54 (0.47-0.64), adjusted after 0.75 (0.70-0.82), p < 0.001). In addition, we observed a decrease in maximal detrusor pressure from 64.3 (49.0-77.0) to 46.4 (32.0-59.0) cm H2O (p < 0.001) and an increase in bladder compliance from 3.0 (2.0-3.3) to 5.6 (3.9-6.6) ml/cm H2O (p < 0.001). There was also significant reductions in leak point pressure from 62.0 (48.0-69.0) to 39.0 (30.0-43.0) cm H2O (p = 0.001), and significant reductions in post-void residual volume (PVR) from 165.0 (128.0-187.0) to 98.0 (68.0-136.0) ml in our 13 patients who could achieve spontaneous voiding (p = 0.001). CONCLUSION: Administering bowel management may be useful for bladder function and urodynamic findings in spina bifida children with DO and DSD. Therefore, bowel management should form an integral part of the treatment in spina bifida children with DO and DSD.

BACKGROUND: The aim of the study was to investigate the association of Cystatin C (CysC) to biochemical markers of bone turnover and bone mass, and to evaluate its prognostic significance in elderly males with chronic heart failure (CHF). METHODS: A prospective cohort study was executed on sixtyeight males (mean age 68±7 years) with mild to moderate CHF, together with 19 of corresponding age- and body mass index-matched healthy individuals who underwent cardio vascular, bone mineral density (BMD), and body com position assessment. Biochemical assessment of all subjects included NT-pro-BNP, parathyroid hormone (PTH), 25-hydroxy vitamin D (25(OH)D), CysC, and biochemical markers of bone turnover including osteocalcin (OC), alkaline phosphatase (ALP), ß-CrossLaps (ß-CTx), osteoprotegerin (OPG), and receptor activator of nuclear factor κB ligand (RANKL). RESULTS: Serum CysC was significantly increased in males with CHF in comparison to healthy control ones. A significant positive association was found between CysC levels and OC in males with CHF, while OC and ß-CTx increased in increasing CysC tertiles. In multivariate regression analysis, OC and smoking were a significant determinant of CysC in males with CHF. Level of CysC was found to be positively associated with an increased fatal risk in males with CHF. CONCLUSIONS: Serum osteocalcin is an independent predictor of CysC level in elderly males with CHF. Higher CysC level showed a negative relation to survival and bone loss in males with CHF. Further research is needed to confirm the potential role of CysC in the crosstalk between heart, kidney, bone, and energy metabolism in CHF.
RESUMO
OBJECTIVE: To examine the effects of bowel management on urinary incontinence in patients with spina bifida associated with overactive bladder (OAB) and detrusor sphincter dyssynergia (DSD). MATERIALS AND METHODS: The research was carried out during the period 2014-2017. A total of 35 patients (group 1) were administered bowel management combined with anticholinergic medication therapy and clean intermittent catheterization (CIC) and 35 patients (group 2) were treated only with anticholinergic medication therapy and CIC. Bowel management included daily enema, laxative application and a special diet, with the aim of treating constipation, evaluated according to the Roma III criteria and echosonographically determined transversal rectal diameter. The effects of the administered bowel management on urinary incontinence were assessed according to the mean dry interval between two CICs for all patients. All patients were followed up for 1 year, during which data were prospectively collected. RESULTS: There was no statistically significant difference with regard to age, gender and baseline clinical features between the two groups. In group 1, the mean ± sd dry interval between two CICs was 150.0 ± 36.4 min, and group 2 it was 101.3 ± 51.6 min. There was a significant difference in urinary incontinence, i.e. in the mean dry interval, between the two groups (P < 0.001). CONCLUSION: Administering bowel management considerably increased the mean dry interval, thus greatly alleviating the symptoms of urinary incontinence. For this reason, bowel management should form an integral part of the treatment of patients with spina bifida and OAB and DSD.

OBJECTIVE: To examine the effects of bowel management on the frequency of urinary infections in spina bifida patients. STUDY DESIGN: The research was carried out from 2014 to 2017, with the recruitment process from June 2014 to March 2016. The first group consisted of 35 patients who were administered bowel management combined with anticholinergic medication therapy and clean intermittent catheterization (CIC). The second group consisted of 35 patients who were treated only with anticholinergic medication therapy and CIC. Bowel management included daily enema, laxative application, and a special diet, with a view to treating constipation that was estimated on the basis of Roma III criteria and echosonographically determined transversal rectal diameter. The effects of the administered bowel management on urinary infections were estimated on the basis of the number of urinary infections before and after the administered therapy. The observation period of every patient was 1 year. RESULTS: There were no significant statistical differences regarding age, gender, and baseline clinical features between the two groups. In the group treated with bowel management combined with anticholinergic medication therapy and CIC, the average number of urinary infections was 0.3 ± 0.5 SD, whereas in the group treated exclusively with anticholinergic medication therapy and CIC the average number of urinary infections was 1.1 ± 1.0 SD. There was a statistical difference regarding urinary infections, that is the average number of urinary infections between these two groups of patients (p < 0.001). CONCLUSION: Administering bowel management considerably decreases the frequency of urinary infections, and should form an integral part of treatment of spina bifida patients.

The use of multidetector computed tomography (MDCT) is an integral part of contemporary diagnostics of Graves' orbitopathy. The aim of this study was to assess proptosis measurement by MDCT and to compare it to the current standard, Hertel exophthalmometry. A cross-sectional study was conducted at the Clinical Centre of Serbia and included 91 patients (19 male and 72 female) with verified Graves' orbitopathy. Globe protrusion measured by MDCT (globe protrusion, GPR) was correlated to Hertel measured protrusion (HR). There was no constant or any systematic bias between the two methods. GPR significantly correlated with the best-corrected visual acuity, while HR did not. Age, body mass index and duration of the disease did not influence proptosis measurement by either method. Proptosis was significantly larger in males. According to our results, GPR compared to HR provides better assessment of the protrusion in Graves' disease. GPR measurement is simple and should always be part of the radiological assessment of orbits in Graves' disease.

Age is an important risk factor for cardiovascular disease in the general population and in dialysis patients. The aim of this study is to investigate the influence of age on the cardiovascular status of asymptomatic predialysis patients with chronic kidney disease (CKD). Echocardiography and carotid ultrasound were performed in 61 patients with CKD stages 4-5, who were divided by age into two groups: group 1 (≥65 years, n = 31) and group 2 (<65 years, n = 30). Data were compared with those of control group (≥65 years, n = 20). Group 1 patients had significantly higher left ventricular mass index (LVMI), (P <0.001), worse LV diastolic function (lower E/A ratio: P<0.05, E' velocities: P< 0.001, E'/A' ratio: P <0.001, and a higher ratio E/E': P <0.05) and a higher prevalence of aortic (P <0.01) and mitral calcification (P <0.001) compared to group 2 patients. Elderly patients also had significantly increased intima-media thickness (IMT, P <0.001) and a greater prevalence of carotid plaques (P <0.05) and calcifications (P <0.001) than younger patients. Multiple regression analysis showed that IMT, LVMI, and E/A ratio were independent variables associated with aging (R2 = 0.605). We concluded that older CKD patients demonstrated more profound structural and functional abnormalities of the myocardium, as well as more prominent vascular changes compared to younger CKD patients. The changes in IMT, LVMI, and E/A ratio are independently associated with aging of CKD patients.

PURPOSE: We aimed at evaluating androgen status (serum testosterone [TT] and estimated free testosterone [eFT]) and its determinants in non-diabetic elderly men with heart failure (HF). Additionally, we investigated its associations with body composition and long-term survival. METHODS: Seventy three non-diabetic men with HF and 20 healthy men aged over 55 years were studied. Echocardiography, 6-min walk test, grip strength, body composition measurement by DEXA method were performed. TT, sex hormone binding globulin, NT-proBNP, and adipokines (adiponectin and leptin) were measured. All-cause mortality was evaluated at six years of follow-up. RESULTS: Androgen status (TT, eFT) was similar in elderly men with HF compared to healthy controls (4.79 ± 1.65 vs. 4.45 ± 1.68 ng/ml and 0.409 ± 0.277 vs. 0.350 ± 0.204 nmol/l, respectively). In HF patients, TT was positively associated with NT-proBNP (r= 0.371, p = 0.001) and adiponectin levels (r = 0.349, p = 0.002), while inverse association was noted with fat mass (r = -0.413, p < 0.001). TT and eFT were independently determined by age, total fat mass and adiponectin levels in elderly men with HF (p < 0.05 for all). Androgen status was not predictor for all-cause mortality at six years of follow-up. CONCLUSIONS: In non-diabetic men with HF, androgen status is not altered and is not predictive of long-term outcome.

BACKGROUND: Closed reduction and percutaneous pinning are the preferred treatment of displaced supracondylar humeral fractures in children. The purpose of this study is to evaluate the non-standard Dorgan's method and compare its results with those of the standard percutaneous cross pinning method in treatment of unstable or irreducible Gartland type II and III supracondylar humeral fractures in children. PATIENTS AND METHODS: This was a prospective evaluation of 138 consecutive patients with Gartland type II or III extension supracondylar humeral fractures referred to University Children's Hospital during a four-year period. The patients were randomized into two groups: the first group, comprised of 71 patients, was treated with standard pin configuration and the second group, comprised of 67 patients, underwent Dorgan's method. The study included 88 boys and 50 girls aged 1.5-11.4 years (mean 6.5±2). At initial presentation 8.7% (n-12) fractures were classified as Gartland type IIa, 25.4% (n-35) as Gartland type IIb and 65.9% (n-91) as Gartland type III. RESULTS: Flynn's criteria were used to evaluate the results. An excellent clinical outcome was reported in about 90% of patients (n-90) treated with standard pin configuration and 89.5% (n-60) of patients treated with Dorgan's method. There were no statistically significant differences in outcomes between the groups in terms of their gender, age, fracture types, function and cosmetics. Neurological lesions were observed in 9.9% of patients (n=7) who were treated using the standard configuration Kirschner pins, while in those treated by Dorgan's method neurological complications were not observed. However, the procedure time was longer (mean 36.54±5.65min) and radiation exposure significantly higher (mean 10.19±2.70 exposures) in the group that was treated using Dorgan's method, compared to the conventional method (mean 28.66±3.76min and 7.54±1.63 exposures). CONCLUSION: Two laterally inserted crossed pins provide adequate stability with good functional and cosmetic outcome for most unstable paediatric supracondylar humeral fractures with no risk of iatrogenic ulnar nerve injury.

This study was conducted to explore the effects of specific psychosocial paradigm on predator animal posttraumatic stress model and to test the hypothesis that psychosocially stressed rats would exibit abnormal levels of cortisol and a larger suppression of cortisol levels after the application of dexamethasone. Animals were divided in two groups: experimental and control groups. The experimental group was exposed to two types of stressors: acute immobilization stress, and combined predator stress and daily social stress with application of dexamethasone. Blood sampling was performed at three different times. We found statistically significant results after analyzing the differences between cortisol levels in different times of blood sampling in the group of animals exposed to stress with dexamethasone application. Statistical significance was found when we compared the experimental group with the control group in terms of elevated cortisol levels during blood sampling after stress paradigm exposition. Many significant disruptions in the functioning of the hypothalamic-pituitary-adrenal axis were observed, such as decrease in basal cortisol levels and enhanced dexamethasone-induced inhibition of cortisol levels. These findings are important because their impact can translate to human individuals with posttraumatic stress disorder, which is the most important role of every animal model in research.

INTRODUCTION: Closed reduction and percutaneous pinning are the most widely used treatment options for displaced supracondylar humerus fractures in children, but there is still no consensus concerning the most preferred technique in injuries of the extension type. OBJECTIVE: The aim of this study was to compare three common orthopaedic procedures in the treatment of displaced extension type supracondylar humerus fractures in children. METHODS: Total of 93 consecutive patients (66 boys and 27 girls) referred to our hospital with Gartland type II or III extension supracondylar humeral fractures were prospectively included in the study over a six-year period. At initial presentation 48 patients were classified as Gartland type II and 45 as Gartland type III fractures. The patients were subdivided into three groups based on the following treatment modality: closed reduction with percutaneous pinning, open reduction with Kirschner wires (K-wires) fixation, and closed reduction with cast immobilisation. The treatment outcome and clinical characteristics were compared among groups, as well as evaluated using Flynn's criteria. RESULTS: Excellent clinical outcome was reported in 70.3% of patients treated with closed reduction with percutaneous pinning and in 64.7% of patients treated with open reduction with K-wire fixation. The outcome was significantly worse in children treated with closed reduction and cast immobilisation alone, as excellent outcome is achieved in just 36.4% of cases (p = 0.011). CONCLUSION: Closed reduction with percutaneous pinning is the method of choice in the treatment of displaced pediatric supracondylar humeral fracture, while open reduction with K-wire fixation is as a good alternative in cases with clear indications.

OBJECTIVE: To compare the effects of antenatal administration of corticosteroids used in two different regimens, on fetal biophysical profile (BPP), baseline fetal heart rate (BFHR), nonstress test (NST) and perinatal outcomes. STUDY DESIGN: We evaluated the effects of single direct intramuscular (i.m.) fetal dose of dexamethasone (4 mg/kg), or four doses of 6 mg dexamethasone given to the mother 12 hours apart on the parameters of fetal BPP 0-4 hours before and after antenatal contraction stress (ACST). We evaluated two groups of 41 fetuses in the 31st gestation week at risk of fetal hypoxia at the Department of Gynecology/Obstetrics, Clinical Center of Serbia in 2013. RESULTS: In fetal ACST group, we found significantly different changes in fetal breathing movement before (D0-f) and after therapy (D1-f), p = 0.019 (-11.75; -1.12), 95% confidence interval (CI), as well as in the maternal ACST group, p = 0.001; (-11.75; -1.12), 95% CI. We found significant difference between BPP 0-m and BPP1-m in the maternal group, p = 0.000. Neonatal asphyxia occurred more often with the increased frequency of fetal breath movements after both ACST (p = 0.04 versus p = 0.07). CONCLUSION: Fetal ACST results in increased fetal breathing movements. Maternal ACST can result in changes to BPP. The increase in fetal breathing movements determinates neonatal asphyxia regardless of the ACST.

INTRODUCTION: An aberrant or accessory crossing renal vessel (CV) leading to the lower pole of the kidney is the most common extrinsic cause of uretero pelvic obstruction(UPJ) obstruction in a child and young adolescent.There is still controversy regarding there functional significance in obstruction Preoperative identification of such vessels may influence surgical management. OBJECTIVE: First aim is to determine the value of magnetic resonance (MR) urography in detecting crossing vessels in children with UPJ obstruction,comparing the data with postoperative findings and the second one is to evaluate morphologic and functional parameters in these hydronephrotic kidneys. MATERIALS AND METHODS: Between June 2009 and December 2012 we retrospectively reviewed MR urography records of one hundred and nine children with unilateral hydronephrosis at the University Children's Hospital. 68 (62.4%) were male and 41 (37.6%) were female,median age was 6.5 ± 5.7. Of the total number of patients, 30 (27%) underwent pyeloplasty, while 79 (72.5%) did not. The age at surgery ranged from 0.3 to 18 years (median 6.6 years). The indication for surgery was based on standard criteria (obstructed renal transit time with or without altered renal function of vDRF < 40%), and did not depend on the presence or absence of a crossing vessel.Consensus reviewes of the MR urography studies were compared with surgical findings. RESULTS: A crossing vessel (CV) was found upon surgery in 9 (33%) of 30 kidneys.On MRU, there was no crossing vessel in 21 kidneys, confirmed at surgery in 18. A crossing vessel was detected with MRU in 9 kidneys and confirmed at surgery in 6. Thus, the sensitivity of MRU was 66.7%, the specificity was 85.7%, the positive predictive value was 66.7%, the negative predictive value was 85.7% and the accuracy was 80%. There was no statistically significant difference in the detection of crossing vessels between MR urography and surgery (p = 0.004 and p < 0.01 respectively). Overall, MRU and surgery showed good agreement (κ = 0.524). CONCLUSION: Based on our results we suggest that MR urography is a reliable and safe diagnostic tool to determine crossing vessels in selected children with UPJ obstruction. Thus, MRU can substitute for other imaging modalities and provide detailed information about the morphology and function of the affected kidney KEY WORDS: Children, Crossing renal vessels, Hydronephrosis, Ureteropelvic function obstruction.

PURPOSE: Bladder autoaugmentation with rectus muscle backing is an efficient surgical technique for bladder augmentation. We evaluated long-term outcomes to determine the value of this procedure. MATERIALS AND METHODS: Between August 1999 and June 2004 autoaugmentation was performed in 16 girls and 7 boys 4 to 13 years old (median age 8). The indication was neurogenic bladder with small capacity and poor compliance due to myelomeningocele in 18 patients, tethered cord in 3 and sacral agenesis in 2. Detrusorectomy usually involved the whole upper half of the bladder. The prolapsed bladder urothelium was hitched to the 2 rectus muscles to prevent retraction and provide easier bladder emptying with voluntary muscle contractions. RESULTS: At the median early followup of 27 months (range 9 to 49) bladder volume had increased significantly in all 23 patients (median 338 ml, range 190 to 462). At the current median long-term followup of 134 months (range 94 to 159) bladder volume continued to be significant compared to median bladder capacity preoperatively (median 419 ml, range 296 to 552). Voluntary voiding was achieved in 14 patients without post-void residual urine. Nine patients used clean intermittent catheterization, of whom only 4 could not empty the bladder voluntarily and relied only on clean intermittent catheterization. CONCLUSIONS: Detrusorectomy with a rectus muscle hitch and backing is a minimally invasive, completely extraperitoneal, simple and safe procedure. However, the technique is indicated only in select cases without anterior abdominal wall anomalies.

BACKGROUND: Among patients with steroid-refractory ulcerative colitis (UC) in whom a first rescue therapy has failed, a second line salvage treatment can be considered to avoid colectomy. AIM: To evaluate the efficacy and safety of second or third line rescue therapy over a one-year period. METHODS: Response to single or sequential rescue treatments with infliximab (5mg/kg intravenously (iv) at week 0, 2, 6 and then every 8weeks), ciclosporin (iv 2mg/kg/daily and then oral 5mg/kg/daily) or tacrolimus (0.05mg/kg divided in 2 doses) in steroid-refractory moderate to severe UC patients from 7 Swiss and 1 Serbian tertiary IBD centers was retrospectively studied. The primary endpoint was the one year colectomy rate. RESULTS: 60% of patients responded to the first rescue therapy, 10% went to colectomy and 30% non-responders were switched to a 2(nd) line rescue treatment. 66% of patients responded to the 2(nd) line treatment whereas 34% failed, of which 15% went to colectomy and 19% received a 3(rd) line rescue treatment. Among those, 50% patients went to colectomy. Overall colectomy rate of the whole cohort was 18%. Steroid-free remission rate was 39%. The adverse event rates were 33%, 37.5% and 30% for the first, second and third line treatment respectively. CONCLUSION: Our data show that medical intervention even with 2(nd) and 3(rd) rescue treatments decreased colectomy frequency within one year of follow up. A longer follow-up will be necessary to investigate whether sequential therapy will only postpone colectomy and what percentage of patients will remain in long-term remission.
