Comparison of early surgical and conservative therapy in children with ureteropelvic junction obstruction.

BACKGROUND: Ureteropelvic junction obstruction is a relatively common urologic problem in children. Most cases present with pelvicaliceal dilatation in antenatal period. Historically most UPJO cases were treated with surgical procedures, but recently many of these children have been treated by nonsurgical observational plans. We compared the outcome of children with UPJO treated in surgical and observational ways. METHODS: In a retrospective study, we assessed the medical history of patients diagnosed as UPJO, march 2011 to march 2021. The case definition was based on grade 3-4 hydronephrosis and obstructive pattern in dynamic renal isotopes can. Patients were put into two groups; Group 1 children were treated with a surgical procedure, and group 2 patients without any surgical procedure for at least a six months' period after diagnosis. We assessed long-term events and improvement of obstruction. RESULTS: Seventy-eight children (mean age 7.32mo., 80% male) enrolled in the study, 55 patients in group one and 23 as group 2. Severe hydronephrosis was the problem of 96% of all patients significantly led to 20% in group 1 and 9% in group 2 (P < 0.001). Severe kidney involvement was observed at 91% in group 1 and 83% in group 2, decreased to 15% and 6%, respectively (P < 0.001). There were no significant differences in sonographic and functional improvement between the two intervention groups. Long-term prognostic issues; growth, functional impairment, and hypertension were not different between the two groups, but group 1 children experienced more recurrence of UTI than group 2 patients. CONCLUSION: Conservative management is as effective as early surgical treatment in the management of infants with severe UPJO.

Comparison of the Efficacy of Tolterodine versus Oxybutynin in the Treatment of Children with Desmopressin-Resistant Enuresis: A Randomized Controlled Clinical Trial.

Background: Enuresis, defined as involuntary nocturnal urination without any underlying organic disorder in a child expected to control urination, poses a common problem. This study evaluated the effectiveness of Tolterodine and Oxybutynin in children presenting with primary desmopressin-resistant enuresis. Materials and Methods: A randomized clinical trial was undertaken involving 68 participants aged between 5 and 16 years, all suffering from primary enuresis. These patients were randomly assigned to one of two treatment groups for a three-month period: Group 1, treated with Oxybutynin and Desmopressin, and Group 2, treated with Tolterodine and Desmopressin. Data on demographics, clinical and laboratory findings, and subjective responses to treatment were gathered. The response was measured based on the frequency of wetting incidents per night and week and compared with pre-treatment data. Results: Patients were divided into two groups (30 patients in Group 1 and 38 patients in Group 2). The mean age of the patients was 88.97±27.09 months. In the first treatment group, 6 out of 30 patients (20%) experienced a complete treatment response, as did 5 out of 38 patients (13.2%) in the second treatment group. This difference between the groups was not statistically significant. Seven patients (23%) in the Oxybutynin group and 13 patients (34%) in the Tolterodine group reported a lack of response to treatment, a difference that also lacked statistical significance. Conclusion: For patients resistant to Desmopressin, the addition of anticholinergic drugs elicited a significant response in over half of the patients. However, no benefit was observed in using either Oxybutynin or Tolterodine in the treatment of Desmopressin-resistant enuresis.

COVID-19 in Coincidence with Transient Distal Renal Tubular Acidosis in an Infant.

Background: Post-COVID-19 nephropathies have been reported profusely in the literature with diverse pathophysiological mechanisms. To the best of our knowledge, this is the first report of transient distal (type 1) renal tubular acidosis (dRTA) in an infant with confirmed COVID-19. Case Presentation. We describe a 32-day-old female with diarrhea and fever without respiratory complaints. Her weight, height, and head circumference were normal for age. The primary lab test showed leukocytosis, neutrophilia, elevated inflammatory markers, and non-anion-gap metabolic acidosis. Real-time polymerase chain reaction (RT-PCR) and elevated SARS-CoV-2 immunoglobulin M confirmed COVID-19, while echocardiography and spiral chest computed tomography scan were normal. Intravenous fluid therapy and supportive care were initiated. Blood culture was positive for Klebsiella pneumoniae. Amikacin and cefotaxime were ordered. Although diarrhea and dehydration gradually improved, venous blood gas still showed metabolic acidosis. Due to the alkaline urine and hypokalemic-hyperchloremic metabolic acidosis, dRTA was diagnosed. Notably, the patient dramatically responded to Shohl's solution. Conclusions: Regarding the various manifestations of COVID-19, the possible association between dRTA and COVID-19 needs further investigation in children.

Prevalence of reflux nephropathy in Iranian children with solitary kidney: results of a multi-center study.

BACKGROUND: Given the importance of the function of the remnant kidney in children with unilateral renal agenesis and the significance of timely diagnosis and treatment of reflux nephropathy to prevent further damage to the remaining kidney, we aimed to determine the prevalence of reflux nephropathy in this subgroup of pediatric patients. METHODS: In general, 274 children referred to pediatric nephrologists in different parts of Iran were evaluated, of whom 199 had solitary kidney and were included in this cross-sectional study. The reasons for referral included urinary tract infection (UTI), abnormal renal ultrasonography, being symptomatic, and incidental screening. Demographic characteristics, including age and gender were recorded. History of UTI and presence of vesicoureteral reflux (VUR) were evaluated. RESULTS: Of the 274 children evaluated in this study with the mean age (SD) of 4.71 (4.24) years, 199 (72.6%) had solitary kidney. Among these, 118 (59.3%) were male and 81 (60.7%) were female, 21.1% had a history of UTI, and VUR was present in 23.1%. The most common cause of referral was abnormal renal ultrasonography (40.2%), followed by incidental screening (21.1%), being symptomatic (14.1%), and UTI (5.5%). In 116 children (58.3%), the right kidneys and in 83 (41.7%) the left kidneys were absent. Besides, 14.6% of the participants had consanguineous parents and 3% had a family history of solitary kidney. Upon DMSA scan, the single kidney was scarred in 13.1%, of which only 7.5% were associated with VUR. In addition, proteinuria and hematuria were observed in 6.5% and 1.5% of children, respectively. CONCLUSIONS: The prevalence of reflux nephropathy was 7.5% in children with solitary kidney with a male predominance. Given the relatively high prevalence of reflux nephropathy in these children, screening for VUR in the remnant kidney appears to be essential in this population.

The Urinary Level of Liver-type Fatty Acid Binding Protein in Children with Febrile UTI.

INTRODUCTION: We assessed the urinary level of L-FABP in patients with APN and compared between patients with scar versus normal kidneys. METHODS: We enrolled children aged 2 months to 12 years old with APN. The urine concentration of L-FABP and L-FABP/Cr were measured. Patients divided into three groups; patients with scarring APN as group 1, patients with non-scarring APN as group 2, and controls. RESULTS: 79 children (aged 57.4 ± 40.5 months, (87.5%) female) enrolled in the study. Group 1 was composed of 19 (16 female) cases, group two 35 (32 female) cases, and group three 26 (2 female) healthy controls. There was no significant difference in absolute urinary level of L-FABP between APN groups and controls. Group 1 patients had a significantly higher concentration than group 2 (P < .05). The UL-FABP /Cr was significantly higher in group 1, than groups 2 and 3 [(0.28 ± 0.39 pg/mg, 0.08 ± 0.08 pg/mg, and 0.10 ± 0.09 pg/mg; respectively), (P < .05, P < .05)]. The difference between group 2 and 3 was not significant (P > .05). The sensitivity and specificity of UL-FABP32 /Cr ratio in prediction of scar was 50% to 72% and 44% to 56%, respectively. CONCLUSION: The urinary ratio of L-FABP to creatinine is not a useful tool for diagnosis of APN or VUR but could be helpful in prediction of long-term potency to renal parenchymal scar formation.

Assessment the Effect of Dexamethasone on Urinary Cytokines and Renal Scar in Children with Acute Pyelonephritis.

INTRODUCTION: One of the most serious complications of acute febrilepyelonephritis in children is the development of renal scar. Thisstudy aimed to investigate the effect of dexamethasone on urinarycytokine levels and renal scar in children with acute pyelonephritis. METHODS: In a double-blind randomized clinical trial, 60 childrenaged 3 months to 12 years with acute febrile pyelonephritis enrolled.The experimental group was treated with a combination of antibioticand dexamethasone, and the control group underwent treatmentwith antibiotic and placebo. The urinary levels of interleukin -6(UIL-6) and -8 (UIL-8) were measured before treatment as baselineand were repeated four days later. RESULTS: 52 cases (23 patients with mean age of 34.19 ± 30.82 monthsin the dexamethasone group, and 29 patients with mean age of50.55 ± 44.41 months in the control group) completed the study. Inthe control group, the UIL-6 and UIL-8 level became significantlylower after four days treatment (P < .05). In the dexamethasonegroup, there was a statistically significant difference between bothUIL-6 and UIL-8 levels before and after treatment (P < .05). Inpatients who had scar on DMSA scan, the mean UIL-8 and UIL-6levels were significantly high before and after treatment. CONCLUSION: Results of this study showed that dexamethasone plusantibiotic have no clear superiority to antibiotic therapy alone indecreasing inflammatory cytokines and scar formation. We foundout that patients with scar had sustained high levels of biomarkersbefore and after treatment.

Urinary matrix metalloproteinase 9 and tissue inhibitor of metalloproteinase 1 biomarkers for predicting renal scar in children with urinary tract infection.

OBJECTIVE: Urinary tract infection occurs in 1.8-6.6% of children under 6 years old. The aim of this study was to assess the urinary concentrations of matrix metalloproteinase 9 (MMP9) and tissue inhibitor of metalloproteinase 1 (TIMP1), in children with acute pyelonephritis (APN) and the potential to develop renal scarring. MATERIAL AND METHODS: Children who had experienced an episode of APN were divided into 2 groups. Group 1 included children with APN who exhibited scarring and group 2 included children with APN who had a normal 99mTechnetium dimercaptosuccinic acid scan. Urinary levels of MMP9 and TIMP1 were measured in the acute phase of infection. A receiver operating characteristic curve was generated to allow calculation of cut-off values. RESULTS: Sixty-one children were enrolled across the 2 groups: group 1 contained 16 patients (all female); group 2, 38 children (36 female and 2 male). Urinary levels of MMP9 and TIMP1 were significantly higher in group 1 than in group 2 (p=0.037 and 0.022 respectively). For comparison of groups 1 and 2, the cut-off values were measured as 75.5 ng/mL (sensitivity 62.5%, specificity 71.1%, positive predictive value, PPV, 48%, negative predictive value, NPV, 82%), 16.1 ng/mL (sensitivity 75%, specificity 55.3%, PPV 41%, NPV 84%), and 1310.7 ng/mL (sensitivity 75% specificity 60.5%, PPV 44%, NPV 85%) for MMP9, TIMP1, and MMP9×TIMP1 levels, respectively. CONCLUSION: Evaluation of urinary MMP9 and TIMP1 levels may help to identify children with APN who are at risk of developing renal scarring.

The urinary and serum levels of IL-32 in children with febrile urinary tract infections.

AIM: We assessed the urinary and serum levels of IL-32 in pediatric patients with acute pyelonephritis (APN) with and without renal scarring. RESULTS: We enrolled children aged 2 months to 16 years with APN. Dimercaptosuccinic acid scans and ultrasonography studies were ordered for all patients, and a voiding. A total of 86 children (aged 57 ± 39 months, 74 [86%] female) were enrolled in this study. Group 1 was composed of 19 (16 female) patients, group 2 of 38 (35 female) patients and group 3 of 29 (23 female) patients. There were no significant differences in the serum and absolute urinary levels of IL-32 (UIL-32) between groups, but the urinary IL-32/creatinine ratio (UIL-32/Cr) was significantly higher in children with pyelonephritis than controls.

Urinary neutrophil gelatinase-associated lipocalin (NGAL) might be an independent marker for anticipating scar formation in children with acute pyelonephritis.

INTRODUCTION: Urinary tract infections (UTIs) are the most serious common bacterial infections among young children. It may affect kidneys that classified as acute pyelonephritis (APN) and may lead to renal parenchymal involvement and scarring with high prevalence rate (15%-60%) among children. This study aimed to assess the urinary concentration of neutrophil gelatinase-associated lipocalin (NGAL) in patients with APN to diagnose those with potency to scar formation. PATIENTS AND METHODS: Children who were admitted with a diagnosis of APN were enrolled and divided into two groups; APN with scar and APN without scar. Urinary levels of NGAL and its ratio to creatinine (Cr) levels were measured in the acute phase of infection. A receiver operating characteristic (ROC) curve was generated to allow calculation of cut-off values. RESULTS: Fifty-four children were enrolled across the 2 groups: group 1 consisted of 16 patients (all female); group 2 consisted of 38 children (36 female and 2 male). Urinary levels of NGAL were significantly higher in APN with scar than in APN without scar (P = 0.037). For comparison of groups 1 and 2, the cut-off values were measured as 7.32 ng/ml, sensitivity; 81.3% and specificity; 66%. CONCLUSION: Evaluation of urinary NGAL levels may help us to identify children with APN who are at risk of developing renal scarring.

Determination of the severity of ureteropelvic junction obstruction using urinary epidermal growth factor and kidney injury molecule 1 levels.

AIM: This study aimed to assess the urinary concentrations of epidermal growth factor (EGF) and kidney injury molecule 1 (KIM-1) in patients with hydronephrosis. METHODS: Neonates with a history of prenatal hydronephrosis were enrolled in three groups. Group 1 included neonates with severe obstruction; group 2 included neonates with milder obstruction; and group 3 included neonates with normal findings on postnatal ultrasonography. RESULTS: 59 neonates were enrolled. The EGF: Cr and KIM-1: Cr ratios were significantly higher in group 1 than in group 2 (p = 0.016 and 0.015, respectively). The cut-off values were measured as 16.855 (sensitivity 71%, specificity 77%) and 0.4765 (sensitivity 81%, specificity 71%) for EGF:Cr and KIM-1:Cr ratios, respectively. The values were significantly higher in group 1 than in group 2. CONCLUSIONS: Evaluation of the urinary KIM-1:Cr ratio may help identify neonates with severe obstructive hydronephrosis.

Role of urinary levels of endothelin-1, monocyte chemotactic peptide-1, and N-acetyl glucosaminidase in predicting the severity of obstruction in hydronephrotic neonates.

PURPOSE: Antenatal hydronephrosis (AH) is found in 0.5%-1% of neonates. The aim of the study was to assess the urinary concentrations of 3 biomarkers, endothelin-1 (ET-1), monocyte chemotactic peptide-1 (MCP-1), and N-acetyl-glucosaminidase (NAG) in severely hydronephrotic neonates. MATERIALS AND METHODS: Neonates with a history of prenatal hydronephrosis were enrolled in the prospective study in 2 groups. Group 1 included neonates with severe forms of obstruction requiring surgical intervention and group 2 included neonates with milder forms of obstruction without any functional impairment. Fresh voided urinary levels of ET-1, MCP-1, and NAG were measured and their ratios to urinary Cr were calculated. RESULTS: Fourty-two neonates were enrolled into the 2 groups: group 1, 24 patients (21 male, 3 female); group 2, 18 neonates (16 male, 2 female). There were no statistically significant differences between urinary ET-1, NAG, MCP-1 values, and ET-1/Cr and NAG/Cr ratios in groups 1 and 2. The urinary MCP-1/Cr ratio was significantly higher in group 1 than in group 2. For comparison of groups 1 and 2, the cut-off values were measured as 0.5709 ng/mg (sensitivity, 75%; specificity, 67%; positive predictive value [PPV], 71%; negative predictive value [NPV], 71%), 0.927 ng/mg (sensitivity, 77%; specificity, 72%; PPV, 77%; NPV, 72%), and 1.1913 IU/mg (sensitivity, 62%; specificity, 67%; PPV, 68%; NPV, 60%) for ET-1/Cr, MCP-1/Cr, and NAG/Cr ratios, respectively. CONCLUSIONS: The urinary MCP-1/Cr ratio is significantly elevated in neonates with severe obstruction requiring surgical intervention. Based upon these results, urinary MCP-1/Cr may be useful in identification of severe obstructive hydronephrosis in neonates.

The role of urinary TIMP1 and MMP9 levels in predicting vesicoureteral reflux in neonates with antenatal hydronephrosis.

BACKGROUND: Antenatal hydronephrosis (AH) is commonly found on evaluation of pregnant women and 20-30 % of neonates have vesicoureteral reflux (VUR). In order to diagnose VUR, we required invasive testing and exposure of the neonate to radiation. The concentrations of a matrix metalloproteinase, MMP9, and its inhibitor TIMP1, were analyzed in hydronephrotic newborns with VUR and were compared to those without reflux. METHODS: The neonates with a history of prenatal hydronephrosis were enrolled in two groups based on imaging study results, the neonates with VUR and without VUR. Neonates with a normal prenatal history and postnatal ultrasound were placed in a third group. We measured the random urinary levels of MMP9, TIMP1, and creatinine, their cut-off values and the MMP9/Cr and MMP9/TIMP1/Cr ratio was calculated, and an ROC curve was drawn. RESULTS: Sixty-nine neonates were enrolled in three groups; 27 patients (20 male, seven female) with AH and VUR were in group 1, 23 neonates (19 male, four female) without VUR were placed in group 2, and 19 (15 male, four female) acted as controls in group 3. The differences between the three groups and the normal and total hydronephrotic groups were statistically significant for MMP9, the MMP9/Cr, MMP9/TIMP1, and MMP9/TIMP1/Cr ratios. The urinary TIMP1 and TIMP1/Cr ratios were not significantly different between the groups. A cut-off value of MMP9 was measured as 358.5 ng/ml (sensitivity [sens] 74 %, specificity [spec] 78 %) and was used to compare groups 1 and 2. For groups 2 and 3, this cut-off was 181.00 pg/ml (sens 91 %, spec 89 %). The cut-off values measured for the MMP9/TIMP1 ratio were 30.32 (sens 70 %, spec 61 %) and 9.85 (sens 96 %, spec 89 %) to compare groups 1 and 2, and 2 and 3, respectively. We found no valuable cut-offs for the TIMP1 and TIMP1/Cr values. There was no difference between neonates with mild, moderate, and severe VUR according to urinary biomarker concentrations. CONCLUSIONS: Evaluation of urinary levels of MMP9, or the MMP9/Cr, MMP9/TIMP1, or MMP9/TIMP1/Cr ratios may help us to differentiate the newborns with hydronephrosis and VUR from those without reflux.

Etiologic and epidemiologic pattern of urolithiasis in north iran;review of 10-year findings.

OBJECTIVE: To determine epidemiologic and metabolic characteristics of renal stone in the northern Iran. METHODS: We prospectively analyzed demographic, clinical and metabolic findings in children less than 16 years old with renal stone revealed by ultrasonography from September 2003 to May 2012. Evaluations included serum and urine measurement of main elements predisposing patients to stone formation. Findings : 271 children (160 males) aged 2 months to 16-years (mean 30 months) were evaluated. 91 (33.6%) had a positive family history, abdominal discomfort (18.8%), UTI (11.8%) and hematuria (11.4%) were main presenting features. 45 children were diagnosed accidentally without any specific compliant. Nearly all (99%) stones lay in kidney., 35.1% had metabolic, 10% infective and 4.1% obstructive trends, 110 children had no definable etiology. Hypercalciuria (25.5%) hyperoxaluria (18.4%) and hypocitraturia (18.1%) were more frequent than uricosuria (8.5%) and cystinuria (3.1%) CONCLUSION: Metabolic derangement plays significant role in stone formation in our area. Patients should be carefully evaluated considering this point of view.

Seroepidemiology of human T-cell lymphotropic virus 1 infection in hemodialysis patients: should we be concerned about it?

Human T-cell lymphotropic virus 1 (HTLV1) is a lymphotropic virus which can be transmitted through unprotected sexual activity, breast feeding, and blood transfusion. Although most of HTLV1-infected individuals remain asymptomatic carriers, 1% to 5% and 3% to 5% develop adult T-cell leukemia and HTLV1-associated myelopathy/tropical spastic paraparesis, respectively. The aim of this study was to determine the prevalence of HTLV1 infection in hemodialysis patients in Sari and Ghaemshahr. This cross-sectional study was conducted on160 patients using random samples selection, and included 80 men and 80 women (mean age, 59.1 ± 14.7 years). All the samples were screened for HTLV1 antibody by enzyme-linked immunosorbent assay and positive samples were confirmed by Western blot assay. Only 1 patient had a positive anti-HTLV1 enzyme-linked immunosorbent assay test, which was confirmed by Western blot. The overall prevalence of HTLV1 seropositivity was 0.6%. The patient was a 21-year-old woman with a history of multiple blood transfusions. She had a history of unsuccessful kidney transplantation and had been on hemodialysis before transplant, too. This study suggests that HTLV1 infection may not be prevalent in high-risk patients in Mazandaran province, and there is no need for HTLV1 screening of blood samples.

Outcome of vesicoureteral reflux in infants: impact of prenatal diagnosis.

OBJECTIVE: Vesicoureteral reflux (VUR) is an important disorder that could be diagnosed in antenatal or postnatal period. The natural history of VUR seems to be different between prenatal or postnatal forms of the disease. We compared the natural history and outcome of vesicoureteral reflux in infants less than one year old diagnosed prenatally or postnatally. METHODS: All infants less than 12 months old with VUR were enrolled in two groups. Group 1 composed of patients with antenatal hydronephrosis and group2, infants with diagnosis of VUR because of UTI or other postnatal problems. We followed patients for an average of 33 months. Outcome was assessed by several factors: somatic growth, need for surgery, resolution, occurrence of UTI and scar formation. FINDINGS: We studied 236 renal units in 152 patients (70 boys, 82girls), 67 patients in group 1 and 85 patients in group2. Occurrence of recurrent UTI was 10.6% with no significant difference between two groups. Reflux resolved in postnatal group more significantly than in the other group (73% vs 49%). Scar developed similarly in both groups (15% vs 25% of renal units). Surgery performed in 7 (8.2%) of postnatal and 4 (6%) of prenatal group with no significant differences between the two groups. CONCLUSION: VUR diagnosed prenatally has similar importance and outcome as postnatal diagnosed one. We suggest performing the same imaging and treatment procedures for prenatally and postnatally diagnosed VUR.

Prevalence of asthma, allergic rhinitis and eczema in elementary schools in Sari (Iran).

BACKGROUND: Allergic diseases including asthma, allergic rhinitis (AR) and eczema are common chronic diseases in children. The purpose of this study was to determine the prevalence of asthma, AR and eczema in Sari, Iran. METHODS: This study was carried out on all elementary schools selected as a cluster from February 2010 to July 2010 in Sari, North of Iran. A questionnaire was provided according to International Study of Asthma and Allergies in Childhood (ISAAC) protocol. Asthma, AR, eczema and their combinations were recorded. RESULTS: Out of the 1818 cases, 646 (35%) subjects had allergic disorder; 223 (12%) had asthma, 318 (17%) had AR and 105 (6%) had eczema The prevalence of allergic disorder in boys (65%) was higher than the girls (40%) (p<0.05). CONCLUSION: The results show that around one - third of the elementary school children have allergic disorders. The prevalence in males is higher than the females.

Doppler ultrasonography as a predictive tool for permanent kidney damage following acute pyelonephritis: comparison with dimercaptosuccinic acid scintigraphy.

INTRODUCTION: The aim of this study was to investigate power Doppler ultrasonography for diagnosis and prediction of scarring compared with technetium Tc 99m dimercaptosuccinic acid scintigraphy in acute pyelonephritis. MATERIALS AND METHODS: Sixty-six children, aged 2 months to 6 years old, admitted with clinical and biological signs of their first febrile urinary tract infection were studied. All of the children underwent PDU and technetium Tc 99m dimercaptosuccinic acid scintigraphy within 7 days after diagnosis and repeat scintigraphy at least 6 months later, if results of the first study were abnormal. Scintigraphic and Doppler studies were interpreted and compared. RESULTS: Dimercaptosuccinic acid scintigraphy demonstrated scar in 7.6% of renal units, 3.1% of patients without reflux and 66.7% of those with high-grade reflux. Kidneys with permanent kidney damage had a mean resistive index (RI) of 0.71 ± 0.06, while the RI value for nonscarred kidneys was 0.66 ± 0.06 (P = .02). The best cutoff point of RI value was 0.715, with a sensitivity of 70%, a specificity of 87.7%, and positive and negative predictive values of 32% and 97%, respectively. These values significantly increased when grey-scale ultrasonography findings were brought into account. Reflux was observed in 19.7% of renal units, which were associated with significantly higher RI values (P = .05). CONCLUSIONS: Power Doppler ultrasonography with a cutoff value of 0.715 has a reasonable sensitivity and specificity for prediction of renal scarring in young children with febrile urinary tract infection.

Circumcision with the plastibell device in hooded prepuce or glanular hypospadias.

PURPOSE: To retrospectively review our experience in infants with glanular hypospadias or hooded prepuce without meatal anomaly, who underwent circumcision with the plastibell device. Although circumcision with the plastibell device is well described, there are no reported experiences pertaining to hooded prepuce or glanular hypospadias that have been operated on by this technique. MATERIALS AND METHODS: Between September 2002 and September 2008, 21 children with hooded prepuce (age 1 to 11 months, mean 4.6 months) were referred for hypospadias repair. Four of them did not have meatal anomaly. Their parents accepted this small anomaly and requested circumcision without glanuloplasty. In all cases, the circumcision was corrected by a plastibell device. RESULTS: No complications occurred in the circumcised patients, except delayed falling of bell in one case that was removed by a surgeon, after the tenth day. CONCLUSION: Circumcision with the plastibell device is a suitable method for excision of hooded prepuce. It can also be used successfully in infants, who have miniglanular hypospadias, and whose parents accepted this small anomaly.
