ABSTRACT
PURPOSE: The study aims to determine the possible improvement in cortical transit time (CTT) after surgery in infants with antenatally diagnosed ureteropelvic junction obstruction (UPJO), and investigate the correlation of CTT with preoperative renal function and parenchymal thickness. PATIENTS AND METHODS: Medical charts of 32 antenatally diagnosed children with UPJO operated on between 2014 and 2021 were reviewed. Patients' demographics, preoperative and postoperative anteroposterior diameter (APD), parenchymal thickness (PT) ratio, differential renal function (DF), drainage patterns and CTT were compared to determine operative benefit. Preoperative CTT of each patient was also grouped as severely delayed (> 6 min) and moderately delayed (3-5 min) and compared. The correlation between the preoperative CTT and preoperative DF and PT ratio was investigated. RESULTS: The median age of the patients was 8.8 months (1-24 months). The CTT (mean: 6.8 ± 3.0 min) was prolonged before surgery and was significantly improved (mean 4.6 ± 1.0 min) after the operation (p < 0.001). A significant negative correlation was detected between the CTT and preoperative DF and between the CTT and preoperative PT ratio. Preoperative DF was found significantly impaired in patients within the severely prolonged CTT group compared to those within the moderately prolonged CTT group. Significant improvement in DF was detected in patients in the severely prolonged CTT group after surgery. CONCLUSION: CTT is a parameter to prove relief of obstruction in patients with antenatally diagnosed UPJO after surgery. CTT is negatively correlated with preoperative DF and PT ratio. Severely prolonged CTT may be considered to be an indication of early surgical intervention.
ABSTRACT
The aim of the study was to reveal the epidemiological characteristics and clinical course of burn patients who were hospitalized in our burn center between 2015 and 2020 and to compare the results between nationalities. The data were retrospectively evaluated in terms of age, gender, time of admission, the total body surface area burned, the degree of burn, the accident location, the presence of wound infection, surgical intervention, length of hospital stay, mortality, educational status of the parents, and nationality; 59.8% of 1496 cases were male, mean age was 40.38 months. The most common age range was 0-2 years. 78.4% were admitted within the first 24 hours; 50.5% of the admissions were from Izmir and its districts. Burn trauma most commonly occurred indoors in all age groups. The most common cause was scalding. Isolation of microorganism in wound cultures was most commonly detected in second degree burns. The most common infection agent was Pseudomonas aeruginosa. The surgical intervention rate was 19%. The mean length of hospitalization was 14.46 ± 12.17 days. Total burned surface, hospitalization time, the infection, and mortality rate were higher in patients who underwent surgical intervention. Parents were mostly primary school graduates. 11.6% of the patients were of foreign nationality. No significant difference was found in the analyzed parameters between nationalities. In conclusion; burn trauma is most commonly seen in the 0-2 age group, regardless of parental education levels. Therefore, it is of great importance to provide training on burns to families and those responsible for the care of children.

BACKGROUND: Urological involvement is rare in patients with coronavirus disease 2019 (COVID-19). Priapism, one of the urological involvements, was reported as one of the COVID-19 comorbidities in the elderly male patient group but has rarely been reported in the pediatric age group. CASE: Herein, a previously healthy 8-year-old patient with COVID-19-associated priapism, which is rare in children, is presented. CONCLUSIONS: During the pandemic, in pediatric cases with priapism of unknown etiology, COVID-19 should be one of the diagnoses to be considered.

OBJECTIVE: To present baseline characteristics and the long-term treatment results of three groups of patients with idiopathic detrusor overactivity (IDOD) and vesicoureteral reflux (VUR) according to different treatment regimens, which underwent endoscopic subureteric injection (STING) in the early phase of targeted treatment (TT) (ES group), underwent STING in the late phase of TT (LS group) and with TT only (TT group). PATIENTS AND METHODS: A total of 49 IDOD cases with VUR which were divided into three groups according to treatment regimens were evaluated in terms of age, symptoms, bladder capacities, involuntary contraction pressures (ICP), presence and degree of renal scar, differential renal functions (DF), new scar formation and STING success. RESULTS: There was no significant difference between the groups in terms of age, side, symptoms, presence of urinary tract infection (UTI), DF, ICP and bladder capacity at diagnosis. A high grade of reflux was found to be significantly lower in the TT group (p = 0.037). There was no significant difference in terms of ICP, DF, bladder capacity and reflux grade between ES and LS Group. But new scar formation was more in LS Group (p = 0.003). CONCLUSION: The STING success is satisfactory in IDOD cases with VUR, waiting a long period of time for diminishing symptoms may cost new scar formation.

OBJECTIVE: Large congenital bladder diverticula (LCBD), congenital bladder diverticula (CBD) larger than 2 cm diameter, is a rare anomaly. The aim of this study was to report long-term surgical and clinical outcomes of children with LCBD. METHODS: Medical charts of all children who were diagnosed with LCBD at our institution between April 2005 and December 2017, with at least 2 year follow-up were retrospectively reviewed. Patients' demographics, symptoms, operative technique, diverticulum size and localization, surgical outcomes and complications were recorded. RESULTS: Fourteen patients with 18 LCBD, all male and age between 7 and 240 months (mean age: 53.5 months) were included in the study. Urinary tract infection was the main complaint in 10. Vesicoureteral reflux was detected in eight patients. Diverticula were 2-5.5 cm (mean 3.3 cm) in size. All diverticulectomies were performed transvesically and ureteroneocystostomy was added in 12 patients, 5 of whom were bilateral. No postoperative infection or recurrent reflux were observed. The median follow-up period was 4.5 years (2-12 years). CONCLUSION: Treatment of LCBD is mostly surgical and transvesical approach for diverticulectomy was found to be a safe and effective surgical procedure in long term follow-up.

BACKGROUND: Button battery lodged in the esophagus carries a high risk of morbidity and mortality. The purpose of this study was to present cases of patients with esophageal button battery ingestion treated at our clinic and to emphasize the importance of early diagnosis and treatment. METHODS: Records of patients admitted to our hospital for foreign body ingestion between January 2010 and May 2015 were retrospectively reviewed. Cases with button battery lodged in the esophagus were included in the study. Patient data regarding age, sex, length of time after ingestion until admission, presenting clinical symptoms, type and localization of the battery, management, and prognosis were analyzed. RESULTS: Among 1891 foreign body ingestions, 71 were localized in the esophagus, and 8 of those (11.2%) were cases of button battery ingestion. Mean age was 1.7 years. Admission was within 6 hours of ingestion in 5 cases, after 24 hours had elapsed in 2, and 1 month after ingestion in 1 case. All patients but 1 knew the history of ingestion. Prompt endoscopic removal was performed for all patients. Three patients developed esophageal stricture, which responded to dilatation. CONCLUSION: Early recognition and timely endoscopic removal is mandatory in esophageal button battery ingestion. It should be suspected in the differential diagnosis of patients with persistent respiratory and gastrointestinal symptoms.

BACKGROUND: Infections are the leading cause of morbidity and mortality in patients with burns in burn units. Bloodstream infections (BSIs) in patients with burns may result from burn wound infection, use of invasive devices such as central venous catheters, and translocation of the gastrointestinal flora. OBJECTIVE: In this study, we investigated the distribution and antimicrobial drug resistance of causative pathogens in children with burns and the durational changes of microorganisms in the distribution of BSIs in children. METHODS: This study was conducted at the Pediatric Burn Unit (PBU) of Dr. Behçet Uz Children Research and Training Hospital during the period of November 2008-April 2015. The study subjects were all the patients admitted to the PBU, in whom microorganisms were isolated at least from one of the cultures, including blood and catheter cultures. RESULTS: Gram-positive bacteria were the most common causative agents of BSI in patients with burns (66.4%), followed by gram-negative bacteria (22.1%) and fungi (11.5%). The median duration of development of BSIs caused by gram-positive bacteria from the time of burn was 5 days (ranging from 2 to 54 days of burn), which was significantly shorter than that of BSIs caused by gram-negative bacteria (12 days) and fungal pathogens (13 days). CONCLUSION: The etiologic agents of BSIs in children may differ from those in adults. Gram-negative drug-resistant bacteria such as multidrug-resistant Pseudomonas aeruginosa and Acinetobacter baumannii were important agents of BSI in patients with burns, especially in the long term; however, gram-positive bacteria should also be considered while deciding the antimicrobial therapy, especially in the early periods of burn.

BACKGROUND: Conservative management procedures are implemented in cases of low-grade pediatric blunt renal trauma, but procedures for grade 4 injuries are not clearly defined. The present objective was to discuss treatment procedures in patients who presented with or developed urinoma during follow-up. METHODS: Treatment procedures implemented in 8 patients (female:male ratio=1:7; average age: 6) with grade 4 renal trauma who presented to the clinic between 2003 and 2012 were retrospectively analyzed. RESULTS: Cause of renal injury was fall in 4 cases, blunt abdominal trauma in 3 cases, and being trapped in a harvesting machine in 1 case. Right renal trauma was diagnosed in 4 cases, left renal trauma in 4. Emergent exploration due to hemodynamic instability was not necessary. Although urinary extravasation was observed upon investigation in 1 patient, urinoma did not form during follow-up. Five of the 7 patients with urinoma were treated with drainage procedures (double-J catheter (JJ) in 3, percutaneous drainage (PD) in 1, followed by JJ catheter placement). In spite of initial PD, inferior pole nephrectomy and pyeloplasty were performed in the remaining 2 cases due to decomposition of the integrity of the urinary system. In 1 patient, pyeloplasty was performed following regression of symptoms due to ureteropelvic obstruction. Catheters were removed when extravasation was not detected in the urinary system. Average time of removal was 4 months for JJ catheters and 1.5 months for PD catheters. DISCUSSION: Pediatric grade 4 renal trauma can be successfully treated with minimally invasive procedures. Initial implementation of these procedures increases the chance of kidney salvage, even when surgical intervention is eventually performed.

INTRODUCTION: Robotic assistance may provide for distinct technical advantages over conventional laparoscopic technique. The goals of this study were (1) to objectively evaluate the difference in the learning curves by novice and expert surgeons in performing fundamental laparoscopic skills using conventional laparoscopic surgery (CLS) and robotic-assisted laparoscopic surgery (RALS) and (2) to evaluate the surgeons' frustration level in performing these tasks. METHODS: Twelve experienced and 31 novices in laparoscopy were prospectively evaluated in performing three standardized laparoscopic tasks in five consecutive, weekly training sessions. Analysis of the learning curves was based on the magnitude, rate, and quickness in performance improvement. The participant's frustration and mood were also evaluated during and after every session. RESULTS: For the novice participants, RALS allowed for shorter time to task completion and greater accuracy. However, significant and rapid improvement in performance as measured by magnitude, rate, and quickness at each session was also seen with CLS. For the experienced surgeons, RALS only provided a slight improvement in performance. For all participants, the use of RALS was associated with less number of sessions in which they felt frustrated, less number of frustration episodes during a session, lower frustration score during and after the session, and higher good mood score. CONCLUSION: The advantages of RALS may be of most benefit when doing more complex tasks and by less experienced surgeons. RALS should not be used as a replacement for CLS but rather in specific situations in which it has the greatest advantages.

Fibroepithelial polyps of glans penis are very rarely seen in childhood. A 6-month-old male admitted to our institution with a slowly enlarging glans penis mass on the ventral side of the glans penis. The mass was totally excised, and hystopathological diagnosis was a fibroepithelial polyp. All of the reported cases published previously, except one, are of adult age and all of them have been associated with the history of long-term condom catheter use. The presence of the case in childhood; however, suggests that the pathology might be congenital. This is the second pediatric case presented in the English literature.
ABSTRACT
BACKGROUND/PURPOSE: To evaluate the success rate of open ureteroneocystostomy (UNC) after failed endoscopic treatment of vesicoureteral reflux (VUR) in children and to discuss the reasons for failure under the light of histopathological findings. METHODS: The clinical data of 371 patients who underwent endoscopic injection for VUR at our institution for the treatment of VUR between January 2008 and January 2014 were reviewed. Patients who were submitted to open ureteral reimplantation following failed endoscopic injection were included in the study. RESULTS: Among 371 patients, 34 (49 ureters) were submitted to open UNC (9.1%). There were 22 female and 12 male patients. Three different injection materials were used; dextranomer/hyaluronic acid in 29, carbon-coated beans in 7 and polyacrylate polyalchohol copolymer in 13. Histological study revealed that the injected material was identified in 34 ureters as malpositioned. Control VCUG 6 months after UNC showed complete resolution in 46 of 47 ureters (97.87%). CONCLUSIONS: Previous endoscopic injection, although causing difficulty in dissection to some degree, does not alter the success rate of UNC. According to the histopathological findings, the cause of failure of injection seems to be attributable to incorrect plane of injection or leakage of the agent after injection.

OBJECTIVE: To investigate the incidence and presentation of ureteral obstruction after endoscopic injection of polyacrylate polyalcohol copolymer (PPC) for the treatment of vesicoureteral reflux, and to analyze its possible causes, together with histopathologic assessment. PATIENTS AND METHODS: The data of 189 patients who underwent endoscopic injection of PPC between May 2011 and December 2013 were retrospectively reviewed. After the injection, patients were followed up by urinalysis and ultrasonography monthly for 3 months. Control voiding cystouretrography was performed in the third postoperative month. Patients were then followed up by ultrasound every 3 months. If a new-onset hydroureteronephrosis (HUN) was observed, control ultrasound was performed monthly to follow the change in the degree of HUN. If a moderate or severe HUN was observed, technetium-99m mercaptoacetyltriglycine or dimercaptosuccinic acid scintigraphy was performed. For patients who needed open surgery, Cohen ureteroneocystostomy was performed. The distal 1 cm of the ureters was resected and examined histopathologically. RESULTS: One hundred eighty-nine patients with 268 refluxing ureters underwent endoscopic injection of PPC. Ureteral obstruction was observed in 3 ureters (1.1%), in 3 female patients of whom the degrees of reflux were grade 4, 5, and 5, respectively. Obstruction showed late onset in all 3 patients. Manifestations of obstruction included pain in 2 patients and recurrent febrile urinary tract infection with loss of function in scintigraphy in 1. All 3 patients underwent open ureteroneocystostomy. CONCLUSION: PPC may cause ureteral obstruction several months or even years after injection. Patients who undergo endoscopic treatment of PPC need long-term follow-up, despite reflux showing complete resolution.

PURPOSE: To show whether Alvarado, Eskelinen, Lintula and Ohmann scoring systems have predictive values in diagnosing acute appendicitis in children. METHODS: Sixty patients with suspected acute appendicitis were prospectively evaluated. Alvarado, Eskelinen, Lintula and Ohmann scores were calculated separately for each patient at the time of admission. The specificity, sensitivity, positive and negative predictive values of the scores were calculated. The predictive value of the scores was evaluated with the receiver operating characteristic (ROC) curve and the consistency among the scores by Kappa test. RESULTS: Twenty of the patients were female (33.3 %). The mean age of the patients was 9.9 years (3-16 years). Forty two patients were operated and appendectomies were performed with the diagnosis of acute appendicitis. The area under the ROC curve showed that the scores had no predictive value in diagnosing acute appendicitis. Kappa test showed that agreement between the scores was not good. CONCLUSION: The sensitivity and specificity of the four scoring systems were not sufficient enough in diagnosing acute appendicitis in our patient group. We concluded that the most important factor affecting the decision for surgery in suspected acute appendicitis is the surgeon's experience combined with physical findings of repeated clinical examinations.

OBJECTIVE: To evaluate the early results of endoscopic treatment of vesicoureteral reflux (VUR) in children using polyacrylate polyalcohol copolymer (PPC). PATIENTS AND METHODS: We retrospectively reviewed 45 patients treated with subureteric injection of PPC in our clinic. The results of voiding cystouretrography performed on the 3rd postoperative month and the results of 1-year follow-up were evaluated. RESULTS: A total of 45 patients (57 ureters) underwent injection of PPC. The mean age of the patients was 6.5 years. There were 6 (10.5%) grade 1, 7 (12.2%) grade 2, 26 (45.6%) grade 3, 16 (28%) grade 4, and 2 (3.5%) grade 5 VUR. There were 11 overactive bladders, 2 duplex collecting systems, and 4 posterior urethral valves among the patients. Voiding cystouretrography postoperatively at the 3rd month showed that VUR had disappeared in 82.5% (47/57) of the ureters, downgraded to grade 2 and 3 in 7% (4/57), persisted in 5.2% (3/57) and upgraded in 5.2% (3/57). The success rate at the end of the first year was 98.1%. The procedure was free of complications such as fever, dysuria, lumbar pain or obstruction in all patients. No patient showed VUR recurrence at the end of the first year. CONCLUSIONS: The short-term results of our patients suggested that PPC can be safely and successfully used in the endoscopic treatment of VUR in children. However, further prospective, controlled trials showing the long-term results of the patients are needed.

Urethral duplication is a rare congenital anomaly. This case study intends to define a new anatomic variation of an accessory urethra. The case is a 5-year-old boy who presented with dorsal chordee requiring operative intervention. At surgery, an accessory urethra on the dorsum of the penis was detected. It was observed that the distal part of the accessory urethra had no external opening and the proximal part had no connection with the native urethra. The accessory urethra was completely excised without complication. To our knowledge, this type of accessory urethra is the first reported case in the English literature.

PURPOSE: Neurogenic bladder dysfunction is a frequent occurrence in association with neoplasms involving the central nervous system. We determine whether tumor location in children with central nervous system neoplasms correlates with specific patterns of urodynamic abnormalities, alleviating the need for urodynamic investigations in these patients. MATERIALS AND METHODS: A total of 62 children with the diagnosis of a central nervous system neoplasm underwent urodynamic investigation after treatment between 1994 and 2004. Patient demographics, tumor location and etiology were assessed. Urodynamic variables recorded included bladder capacity, early and late compliance, voiding pressure and post-void residual volume. For comparative analysis patients were grouped according to central nervous system level of involvement. Statistical analysis was performed, with p<0.05 considered significant. RESULTS: Mean±SD patient age at urodynamic evaluation was 10.6±7 years. Tumor was located intracranially in 21% of patients and in the spinal cord in 79% (cervical/thoracic in 27%, lumbar in 27%, sacral in 47%). There was no correlation between tumor location and any specific bladder dynamic parameter (p>0.05). Similarly there were no significant differences in urodynamic findings in patients with intracranial vs extracranial tumors, or in those with sacral vs suprasacral involvement. CONCLUSIONS: Abnormalities in urodynamic parameters in children with a central nervous system tumor cannot be predicted based on the location of tumor involvement. Therefore, urodynamic evaluation is appropriate in all patients with neoplastic involvement of the central nervous system, regardless of the tumor location, for best management of lower urinary tract function.

BACKGROUND: Sucralfate is widely used as a cytoprotective agent in patients with peptic ulcer and other intestinal mucosal injury. The aim of this study is to investigate whether sucralfate has any effect on the prevention and treatment of hypoxia/reoxygenation-induced intestinal injury. MATERIAL/METHODS: Four groups of 10 1-day-old rat pups were studied. Hypoxia/reoxygenation (H/O)-induced intestinal injury was created. Group 1 was subjected to H/O just after birth and sacrificed at the end of the third day (Treatment Control). Group 2 was subjected to H/O just after birth and treated with sucralfate for 3 days. They were sacrificed at the end of the third day (Treatment). Group 3 was subjected to H/O on the third day after birth and then sacrificed (Prophylaxis Control). Group 4 was treated with sucralfate for the first 3 days, then H/O was created. Just after H/O, the pups were sacrificed (Prophylaxis). The intestinal tissues were harvested for histopathological investigation. Malondialdehyde (MDA) levels in the intestinal tissues were determined. RESULTS: The mucosal injury grades of the treatment and prophylaxis groups were significantly lower than those of control groups (p<0.05). The mean MDA level in the treatment and prophylaxis groups were 0.42+/-0.17 and 0.21+/-0.23 nmol/mg respectively. The MDA levels of both groups were significantly lower than in the control groups (p<0.05). CONCLUSIONS: The present study shows that sucralfate has beneficial effects in an experimental model of hypoxia/reoxygenation-induced intestinal injury.

Although congenital pyloric atresia commonly occurs in isolation, it has rarely been reported in association with other alimentary tract atresias. This is a report of a newborn with congenital pyloric atresia associated with duodenal atresia, jejunal atresia, apple-peel ileal atresia, and pylorocholedochal fistula. Preoperative diagnosis was duodenal atresia because of bilious vomiting, and erect radiogram showed double bubble sign. The presented case is the first report of such an association.

BACKGROUND: The primary goal of surgical therapy for short bowel syndrome is to increase intestinal absorptive capacity. Many surgical procedures have been described for this purpose. One of these is ileal reverse-segment procedure. This procedure after massive small-bowel resection is an alternative way to treat short bowel syndrome, but how it affects intestinal morphology in short bowel syndrome has not been investigated. The aim of this study is to investigate macroscopic and microscopic effects of reverse-segment procedure on the short bowel. METHODS: Twenty rats underwent resection of 80% of the small bowel. The rats were separated into two groups (n = 10). In the first group (reverse group), a reverse segment was formed by twisting a 2-cm ileal segment 180 degrees, without damaging its vascularity. In the second group (control group), a 2-cm ileal segment was resected, preserving its mesentery, and end-to-end anastomosis was performed to maintain the intestinal passage. The segment was not twisted 180 degrees. The 2-cm proximal (jejunal) and distal (ileal) segments of the resected bowel were reserved for histologic investigation. Two months later, the rats were killed and the jejunal and ileal segments were evaluated morphologically. RESULTS: In the reverse group, body weight and total intestinal length significantly increased (14% more than in the control group). The diameter of both proximal (jejunal) and distal (ileal) segments in the reverse group also increased 53.8% and 22.8%, respectively ( P < 0.05). Histologically, crypt depth and villus height of the ileal segment in the reverse group increased 15.2% and 18.2% more than in the control group ( P < 0.05). No histologic change was observed at the jejunal level except for intestinal muscle thickness. CONCLUSIONS: Ileal reverse-segment procedure in rats with short bowel syndrome 1) does not cause intestinal obstruction, 2) increases total bowel length and body weight, 3) increases the diameter of both jejunal and ileal segments, and 4) increases villus height and crypt depth only at the ileal level. For this reason, reverse-segment procedure positively affects intestinal adaptation.
