RESUMEN
Upper tract urothelial carcinoma (UTUC) in a duplex collecting system (DCS) is a relatively uncommon presentation with unclear management guidelines. Herein, we retrospectively reviewed all published cases of DCS with UTUC aiming to suggest personalized clinical care options for future cases. We conducted a systematic search for all cases of UTUC in DCS from published literature using the following keywords: UTUC, urothelial carcinoma (UC), collecting duct carcinoma, and DCS. The cases were summarized based on demographics, clinical presentation, predisposing risk factors, tumor location, management, and follow-up. We present an additional case based on our experience with a 69-year-old female with high-grade (HG) UTUC of the upper moiety in complete DCS. The patient underwent a robotic upper pole hemi-nephroureterectomy (hemi-NU) with a common sheath distal ureterectomy and a bladder cuff, followed by lower pole ureteral reimplantation. Overall, 34 patients with 35 renal units of UTUC in DCS were included and analyzed. To conclude, UTUC of DCS is rare and underreported. Hence, it is difficult to define a standard treatment. Although hemi-NU has been previously described, to the best of our knowledge, this is the first case report of robot-assisted hemi-NU for complete DCS with single-moiety UC.
RESUMEN
PURPOSE: To examine the accuracy of cystography under general anesthesia in children with vesicoureteral reflux (VUR). MATERIALS AND METHODS: A prospective study of children who had VUR on cystography without general anesthesia (i.e., the gold-standard), and who are candidates for endoscopic VUR repair surgery. All children subsequently underwent a cystography under general anesthesia before injection using standardized method, which was compared to the gold-standard cystography. χ2 and Mann-Whitney U tests were used to compare proportions and medians between groups. RESULTS: Between 2017 and 2021, 126 renal units in 13 boys and 50 girls were included. Median age was 3.4 years (interquartile range [IQR] 1.5-6.5). Median time from cystography without to cystography with general anesthesia was 3.8 months (IQR 2.7-6). Of the 126 renal units, 96 had VUR on cystography without general anesthesia. On dichotomous analysis (no VUR vs. any VUR) sensitivity, specificity, negative and positive predictive values of cystography under general anesthesia were 47% (45/96), 87% (26/30), 34% (26/77) and 92% (45/49), respectively. Accuracy was 56.3%; Cohen's Kappa coefficient was 0.22, indicating poor agreement. In subgroup analysis, the sensitivity of cystography under general anesthesia was significantly lower in primary VUR (20% vs. 55% in secondary VUR, p = 0.01) and active VUR (14% vs. 52% in passive VUR, p = 0.008). CONCLUSION: Cystography under general anesthesia was poorly correlated to cystography performed while the child was awake or lightly sedated. Clinical decision relying on this cystography is questionable.

OBJECTIVE: Abnormal healing after neonatal ritual circumcision is a source of significant concern to patients' parents and their caregivers. This report presents a series of male infants who underwent ritual circumcision and subsequently developed obliteration of the normally distinct structure of the corona. METHODS: We report a case series of infants recruited from the community and a medical center. The compulsory inclusion criterion was absence of the normal landmarks of the glans penis with confirmed integrity of normal male genitalia. Illustrative cases are presented. The possible pathogenetic mechanisms leading to this condition are discussed. A literature search was conducted to discern whether this phenomenon has ever been previously reported. RESULTS: The eight cases we diagnosed were all otherwise normal. In one case, where we discovered use of an active substance on the circumcision wound, the condition persisted for an extended period but it resolved completely by 15 months of age. In all but one of the subjects the condition was transient and resolved over time. We could not reveal any previous publication on this topic. DISCUSSION: This noteworthy complication of circumcision raises debate whether it was previously existent, though unreported or a novel phenomenon. We postulate that contributing factors leading to tissue injury may possibly be injured tissue exposure to irritating substances, vascular compromise, the technique chosen to control bleeding or an idiosyncratic response to tissue trauma. More attention to the occurrence of this phenomenon is compulsory to collect more data and learn of its incidence and eventual impact. CONCLUSIONS: Obliteration of the corona, constitutes an unreported, rare albeit significant complication following circumcision. We recommend refraining from potentially inciting factors leading to this undesirable condition. More extensive experience with this disorder may enable us to employ preventive measures to eliminate it or at least provide reassurance wherever possible.

As far as we know this is the first report on bulking agent injection into intravesical ectopic ejaculatory orifices reported in the English literature. During a follow-up period of 23 months, the child was free of episodes of epididymo-orchitis. Deflux injection in this rare anomaly of intravesical refluxing ducts had prevented irreversible damage to the testes from recurrent EO. Thus, it may be a better option than vasectomy when antibiotic treatment fails.

OBJECTIVE: To assess the postpubertal outcome of ventral penile curvature repaired in infancy in terms of recurrence and aesthetics. MATERIALS AND METHODS: Postpubertal patients treated for hypospadias and ventral penile curvature in infancy at a tertiary medical center were invited to undergo assessment of the quality of the repair. Findings were compared between patients with a straight penis after skin release and patients who required dorsal plication. RESULTS: The cohort included 27 patients of mean age 16.5 years who were reported with straight penis after surgery. Postpubertal curvature was found in 6 of 14 patients (43%) successfully treated by skin release and 10 of 13 patients (77%) who underwent dorsal plication (P = .087). Significant curvature (≥30 degrees) was found in 1 of 14 patients in the skin-release group and 4 of 13 in the dorsal plication group (P = .16). Rates of redo urethroplasty were 2 of 14 (14%) and 5 of 10 (50%), respectively. Patient satisfaction with the appearance of the penis did not differ significantly. CONCLUSION: Ventral penile curvature repaired in infancy often recurs after puberty. The need for dorsal plication has a trend-level association with recurrence of penile curvature in puberty. It might also be related to the degree of postpubertal penile curvature and the need for redo urethroplasty. Procedure type does not affect patient satisfaction with the postpubertal appearance of the penis.

OBJECTIVE: To report the characteristics, treatment, and short-term outcome of neonatal post-circumcision bleeding, and to identify predictors of surgical treatment. MATERIALS AND METHODS: The medical records of 90 consecutive neonates who presented to the emergency room with post-circumcision bleeding between 2009 and 2014 were reviewed. Circumcisions were performed using the traditional Mogen shield device. The study end point was surgical intervention for hemostasis. Predictors of surgical treatment were evaluated. RESULTS: An estimated total of 28,383 circumcisions were performed during the study period; thus, the post-circumcision bleeding rate was 0.32%. Initial treatment included compressive dressing in 15 infants (17%) and hemostatic dressing in 47 infants (52%); 28 infants (31%) did not require treatment upon arrival to the emergency room. Two infants (2%) received blood transfusion. Surgical treatment was required in 11 infants (12%); 10 of 43 infants (23%) with active bleeding on arrival to the emergency room required surgery compared to 1 of 47 infants (2%) without active bleeding (P = .003). Similarly, 3 of 7 infants (43%) referred from other hospitals required surgery compared to 8 of 83 infants (10%) referred from the community (P = .037). Abnormal blood tests at presentation were not associated with surgical treatment. At 1 month of follow-up, 2 infants were admitted for recurrent bleeding. Coagulation abnormalities were found in 4 infants. CONCLUSION: Surgical treatment was required in 12% of infants presenting to the emergency room with post-circumcision bleeding. The rate of surgical intervention was significantly higher in infants with active bleeding at presentation and in those referred from other hospitals. Physicians should consider admitting infants presenting with active post-circumcision bleeding, whereas infants without active bleeding may be observed and discharged.

OBJECTIVE: To describe the incidence of missed diagnosis and delayed presentation in children with testicular torsion, and to identify associated risk factors. MATERIALS AND METHODS: The medical records of all children over 1 month of age diagnosed with testicular torsion between 2008 and 2014 were reviewed. Data pertaining to patient characteristics and treatment outcome were collected. Orchiectomy was categorized as caused by either delayed presentation or missed diagnosis. Logistic regression analyses were used to evaluate the association between patient characteristics and treatment outcome. RESULTS: The study cohort included 100 children, 40 of whom underwent orchiectomy. Twenty-eight patients arrived with delayed presentation, and 12 were incorrectly diagnosed. On univariable logistic regression analyses, young age, long duration of pain, and prior community clinic examination were significantly associated with orchiectomy. Similarly, these variables were associated with delayed presentation and missed diagnosis when compared with the orchiopexy group. On multivariable analysis, young age and long duration of pain remained significant predictors of orchiectomy. Doppler ultrasound was performed in 70 patients; 7 of 70 ultrasounds were incorrectly diagnosed. Young age was associated with missed sonographic diagnosis, whereas ultrasound performer (senior radiologist vs resident) and time of the day were not. CONCLUSION: Missed diagnosis may account for up to 12% of orchiectomy cases. Younger age and prior community clinic examination increase the risk of incorrect diagnosis. Doppler ultrasound should be used with discretion and its results interpreted cautiously.

BACKGROUND: Studies in the past have shown that children with spinal dysraphism have highly prevalent latex allergy. These children have a spectrum of congenital spinal anomalies, caused by defects in neural tube closure, with an incidence of 1 in 1000 births. Proposed risk factors for latex allergy include multiple surgeries since birth, including an insertion of a ventriculoperitoneal shunt, elevated IgE titers, repeat multiple catheterizations, and atopy. In the 1990 s, studies published in the United States and Europe showed a latex allergy prevalence of over 70% in these patients. On the other hand, studies published years later in other countries showed a declining prevalence of no more than 17%. OBJECTIVE: Our goal was to prospectively assess the prevalence of latex allergy in children with spinal dysraphism in our non-latex free environment center compared with a control group. STUDY DESIGN: The study group included 58 children with spinal dysraphism attending our center between 2010 and 2013. Findings were compared to 65 children referred for evaluation of allergic diseases. The parents completed questionnaires assessing personal and familial history of allergic diseases. All children were tested for blood latex IgE-specific antibodies (IMMULITE 2000). RESULTS: The mean age was 120.9 (67.6) months in the study group and 129.5 (68.5) months in the control group (p = 0.27). The corresponding median number of surgical procedures was 2 (range 0-10) and 0 (range 0-4), and mean duration of clean intermittent catheterization was 52 (72.2) months in the study group. Positive IgE antibodies and clinical allergic reactions were low with very similar prevalence in both groups (Figure). DISCUSSION: Our results show considerable lower latex allergy and sensitization than studies published in the United States and Europe in the past, despite the fact that our center utilizes minimal avoidance measures for latex allergy. Study limitations include the relatively small number of patients in our single-center study. Moreover, our control group could not include normal volunteering healthy children due to institutional review board refusal. CONCLUSIONS: Children with spinal dysraphism in our center have a low prevalence of latex allergy. Possible explanations include low latex protein content gloves and catheters used worldwide, including our center, lower number of surgeries, or a disease associated propensity for latex sensitization with a geographically variable genetic association. More studies are needed to validate our conclusion that using minimal avoidance measures, without maintaining a strict latex free environment, seems sufficient to prevent clinical latex allergy, at least in the Mediterranean region.

OBJECTIVE: To describe the causes and outcome of urinary retention in children and assess its prevalence by gender and age. METHODS: The medical records of all children (aged <18 years) who presented to the emergency room with acute urinary retention from 2000 to 2012 were reviewed. Patients with postoperative urinary retention, a known neurologic disorder, and neonates were excluded. Data were collected on patient demographics and cause, treatment, and outcome of the urinary retention. Findings were evaluated and compared by age and gender. RESULTS: The study group comprised 42 boys (75%) and 14 girls (25%). Median follow-up time was 25 months. Causes of urinary retention were mechanical obstruction in 14 patients (25%), infection or inflammation in 10 (18%), fecal impaction in 7 (13%), neurologic disorders in 6 (11%), gynecologic disorders in 4 (7%), and behavioral processes in 3 patients (5%); 12 patients (21%) were idiopathic. All patients with mechanical obstruction were boys, of whom 5 had a pelvic tumor. Age distribution was bimodal: 29% of the events occurred between ages 3 and 5 years, and 32%, between ages 10 and 13 years. Fifteen children underwent surgery. Three children required continuous catheterization during follow-up. CONCLUSION: Urinary retention in children is characterized by a variable etiology and bimodal age distribution. The high rate of severe underlying disease is noteworthy and should alert physicians to the importance of a prompt, comprehensive, primary evaluation of this patient population in a hospital setting to initiate appropriate treatment and avoid complications.

INTRODUCTION: Epididymitis in patients with anorectal malformation (ARM) represents a unique problem because unlike the general population, an underlying urinary tract problem is frequently identified. We review our experience with epididymitis in ARM population with an emphasis on examining urologic outcomes. MATERIALS AND METHODS: We performed a retrospective review of male patients with ARM cared for from 1980 to 2010. Clinical and pathologic variables recorded included age at presentation, recurrence, associated urologic anomalies, incidence of ureteral fusion with mesonephric ductal structures, glomerular filtration rate and urodynamic parameters. RESULTS: Twenty-six patients were identified with documented episodes of epididymitis. Renal injury was noted in five patients (19%), all of whom were diagnosed with neurogenic bladder (NGB) several years after anorectoplasty. NGB was found in ten patients (38%) in our series. Ectopic insertion of ureter into a mesonephric ductal structure was discovered in five patients (19%). Twelve patients (46%) had recurrent episodes of epididymitis, with seven of these patients (58%) being diagnosed with NGB. Two patients in the pubertal group presented with a history of epididymitis and complained of ejaculatory pain. CONCLUSION: Epididymitis in a patient with ARM warrants a comprehensive urologic investigation, particularly in recurrent episodes. Attempts at surgical intervention (e.g. vasectomy) should be avoided until functional assessment of the urinary tract has occurred. Failure to recognize this association may lead to potentially avoidable complications and morbidity. Long term urological follow up of these patients is warranted to identify at risk patients and minimize renal deterioration.

OBJECTIVE: To review the characteristics and treatment outcome of testicular torsion in infants, aged 1 month to 1 year, and compare them with those seen in neonates. METHODS: The study group included 30 patients aged younger than 1 year who were treated for testicular torsion at a tertiary pediatric medical center between 1993 and 2012. Medical records were retrospectively reviewed for clinical characteristics and treatment outcome. Findings were compared between patients who presented before age 1 month (neonate group, n = 17) or later (infant group, n = 13). RESULTS: The common clinical presentation in the neonate group was a solid, nontender scrotal mass apparent in 13 of 17 patients (76%). In the infant group, 11 of 13 patients (85%) presented with restlessness and 12 of 13 (92%) with a tender scrotal or inguinal mass. Torsion of an undescended testis was significantly more prevalent in infants, 7 of 13 (54%), than neonates, 1 of 17 (6%; P = .009). Although extravaginal torsion was documented in 5 of 6 neonates (83%), 8 of 9 infants (89%) had an intravaginal torsion (P = .011). Orchiectomy was performed in 14 of 17 neonates (82%) and 6 of 13 infants (46%; P = .056). Of the 29 patients with follow-up data, testicular salvage was documented in 1 of 17 neonates (6%) and 2 of 12 infants (17%), at a minimum follow-up of 5 months (P = .55). CONCLUSION: Testicular torsion in the first year of life is a diverse condition. Although neonatal torsions were predominantly extravaginal, infantile torsions were mostly intravaginal, involving undescendent testes in more than half of the cases. Despite fewer orchiectomies performed on the infant group, testicular salvage rates in both groups were similarly low.

PURPOSE: We histologically investigated the cause of failed endoscopic treatment of vesicoureteral reflux with dextranomer/hyaluronic acid injections in children. MATERIALS AND METHODS: A total of 192 children underwent dextranomer/hyaluronic acid injection at our institution between January 2008 and September 2010. The study population consisted of 13 children (22 ureters) with vesicoureteral reflux who underwent ureteroneocystostomy following failed endoscopic injections (1 to 2) of dextranomer/hyaluronic acid. In all cases the dextranomer/hyaluronic acid was implanted in the mucosa of the mid to distal ureteral tunnel following hydrodistention of the ureter. The medical records were reviewed, and specimens of the archived distal ureters removed during surgery were examined histologically. RESULTS: Mean patient age was 4.1 years. Mean dose of dextranomer/hyaluronic acid was 0.9 ml (both treatments) and mean lag between treatments was 13.4 months. Indications for open surgery were recurrent urinary tract infections and/or residual or aggravated reflux grade IV or higher. Histological study revealed that the dextranomer/hyaluronic acid was malpositioned in 21 of 22 ureters, residing in the muscle fibers in 2, adventitia in 14 and periureteral space in 5. CONCLUSIONS: This is the first known study to provide a histologically proved cause of failure of endoscopic treatment of vesicoureteral reflux with dextranomer/hyaluronic acid injections in children. Malpositioning of the material outside the submucosal ureter was identified in a high percentage of cases. Larger studies are needed to corroborate these findings.

PURPOSE: One of the main ergonomic challenges during surgical procedures is surgeon posture. There have been reports of a high number of work related injuries in laparoscopic surgeons. The Alexander technique is a process of psychophysical reeducation of the body to improve postural balance and coordination, permitting movement with minimal strain and maximum ease. We evaluated the efficacy of the Alexander technique in improving posture and surgical ergonomics during minimally invasive surgery. MATERIALS AND METHODS: We performed a prospective cohort study in which subjects served as their own controls. Informed consent was obtained. Before Alexander technique instruction/intervention subjects underwent assessment of postural coordination and basic laparoscopic skills. All subjects were educated about the Alexander technique and underwent post-instruction/intervention assessment of posture and laparoscopic skills. Subjective and objective data obtained before and after instruction/intervention were tabulated and analyzed for statistical significance. RESULTS: All 7 subjects completed the study. Subjects showed improved ergonomics and improved ability to complete FLS™ as well as subjective improvement in overall posture. CONCLUSIONS: The Alexander technique training program resulted in a significant improvement in posture. Improved surgical ergonomics, endurance and posture decrease surgical fatigue and the incidence of repetitive stress injuries to laparoscopic surgeons. Further studies of the influence of the Alexander technique on surgical posture, minimally invasive surgery ergonomics and open surgical techniques are warranted to explore and validate the benefits for surgeons.

PURPOSE: Ureteral obstruction due to benign strictures is a significant complication of radical cystectomy and urinary diversion for bladder cancer that can lead to renal function loss and infection related morbidity. Treatment may be performed surgically or with minimally invasive techniques. We describe the 10-year experience at our department with various treatment modalities for post-cystectomy benign strictures. MATERIALS AND METHODS: The study group consisted of 28 patients treated for benign ureteral strictures following radical cystectomy for bladder cancer. Their medical records were reviewed for clinical presentation, diagnostic procedures, treatment and long-term outcome. RESULTS: The study group represented 12.7% of all 221 patients treated at our department with radical cystectomy for bladder cancer in 1994 to 2004. Ureteral strictures were asymptomatic in 71.4% of cases. Median time to diagnosis was 7.0 months and 75% of the patients were diagnosed within year 1 after cystectomy. Treatment consisted of stenting, dilation and open surgical revision with removal of the strictured segment and reanastomosis. Median followup was 62.5 months. The stenting procedures served as the long-term definitive treatment in 45% of cases, whereas balloon dilation uniformly failed. Although open surgical revision was technically challenging, it had a long-term success rate of 93%. CONCLUSIONS: Benign ureteral strictures commonly occur during postoperative year 1 and they are usually asymptomatic. Early diagnosis and prompt drainage are required to prevent consequent renal parenchymal loss and infectious complications. Although minimally invasive procedures are viable treatment alternatives, open surgical revision is still the preferred long-term definitive treatment.

BACKGROUND: Primary insulin-like growth factor-I (IGF-I) deficiencies, such as in Laron syndrome (LS), are a unique model in man to study the consequences resulting from defects in growth hormone (GH) signal transmission. OBJECTIVE: To assess retrospectively the effect of IGF-I deficiency and its therapy on the various cells of the hematopoietic system as reflected by peripheral blood counts. PATIENTS AND METHODS: Two groups of patients were studied. The first group consisted of 11 untreated patients with LS, seven males and four females, who were followed from childhood into adult age. Average age at the time of data analysis was 45.4 +/- 9.6 years. The second group included ten children with LS, six males and four females, who received IGF-I replacement therapy for an average period of 6 years, ranging in age from 0.9-11 years. The mean age at initiation of therapy was 6.9 +/- 4.28 years. Only the seven children treated for 5 years or more were included in the analysis. Data on blood counts were collected from the patients' charts. Blood samples were drawn at baseline, weekly during the first month, once a month during the first year, and once every 3 months thereafter. Statistical analysis of the change over time was performed using repeated measures ANOVA. RESULTS: Children with LS had red cell indices in the lower normal range and an elevated monocyte count. A statistically significant rise in red blood cell (RBC) indices was seen in children during IGF-I therapy: RBC rose from 4.66 x 10(6)/ml to 4.93 x 10(6)/ml (p = 0.011); hemoglobin from 11.55 g/dl to 13.01 g/dl (p < 0.001); hematocrit from 34.94% to 38.52% (p = 0.007), and mean corpuscular volume from 72.27 fl to 79.93 fl (p < 0.001). The platelet count diminished significantly during IGF-I therapy from 316 x 10(3)/ml to 219 x 10(3)/ml (p = 0.02), and the monocyte count from 0.74 x 10(3)/ml to 0.49 x 10(3)/ml (p < 0.001). CONCLUSIONS: The present investigation, the first of its kind in this syndrome, confirms that IGF-I has a strong stimulatory effect on erythropoiesis. In addition, IGF-I therapy had a reducing effect on monocytes and platelets, an effect not previously described. The mechanism by which IGF-I mediates these effects needs further elucidation.

PURPOSE: To review and update several aspects of testicular torsion. INCIDENCE: The relative incidence of testicular torsion, torsion of testicular appendix and epididymo-orchitis is variable and depends on mode of diagnosis and patients' age. AGE: Testicular torsion can occur at any age. The peak is in adolescents below the age of 18 years. SYMPTOMS: Classical symptoms are not always present. Range of duration is varied. Nausea and vomiting are positive predictive value for testicular torsion. PHYSICAL EXAMINATION: Main findings predicting testicular torsion are absence of cremasteric reflex and diffuse tenderness. IMAGING: Color Doppler Ultrasound can assess in equivocal and low clinical suspicious conditions for testicular torsion. NEONATAL TORSION: There are two conditions in this age group; the prenatal that urgent exploration is in controversy and postnatal that urgent surgery is required. LATE OUTCOME: Early salvage rate and late atrophy depends on duration and degree of torsion. MEDICOLEGAL: Testicular torsion is an active area of malpractice litigation. Late presentation and atypical presentations do not affect the medicolegal outcome.
