Comparative Study
A comparative bibliometric analysis of the top 150 cited papers in hypospadiology (1945-2013).
Hypospadias, the most common congenital malformation of the penis, is characterized by an abnormal ventral opening of the urethral meatus, abnormal ventral curvature of the penis, and an abnormal distribution of the foreskin around the glans, with a ventrally-deficient hooded foreskin, and has been described in modern peer-reviewed literature since Noble's description in 1853. A dramatic increase in the literature on hypospadiology has focused on two main topics: The aetiology of the condition including molecular mechanisms and environmental influences, as well as surgical techniques to repair the defect, however there have been a number of facets of research stemming from this poorly understood condition in a developing subspecialty (Figure). The majority of these publications focus on the evolution of surgical technique and management. Urethral reconstruction should offer the ability to stand to urinate and combine a satisfactory cosmetic result. The tubularized incised plate repair, popularized by Snodgrass et al., and the Mathieu repair, have been the mainstay for distal hypospadias, however, there have still been a large number of well-described techniques, with no consensus as to the ideal method of repair, some of which is attributed to non-uniform standards of reporting outcomes. There is also no standard objective means to qualitatively assess the importance of each of these contributions. ⋯ Although there are inherent potential elements of bias in citation analysis, this study demonstrates that citation analysis in a complicated topic can provide a high-throughput, uncomplicated method of quickly deciphering important contributions of authors and institutions to the field of hypospadias research.

Comparative Study
Functional outcomes of early versus delayed pyeloplasty in prenatally diagnosed pelvi-ureteric junction obstruction.
Although initial conservative management is popular in the management of antenatally detected pelvi ureteric junction (PUJ) obstruction [1-3], several authors [4,5] have questioned this approach and expressed concern about failure to recover the function lost during expectant management following surgery. In this single center prospective study, we have compared the functional outcomes following early versus delayed pyeloplasty in SFU grade 3-4 PUJ obstruction. ⋯ Although several publications [1-3] have reported functional recovery during initial conservative treatment of PUJ obstruction, in our study a large proportion of patients (80%) in Group II had loss of function during follow-up. This is probably because the study population included only SFU grade 3-4 with obstructive renogram. Several authors have expressed concern about irreversible loss of renal function during expectant management [4,5]. Findings of our study reveal that irrespective of initial SRF, early pyeloplasty in prenatally diagnosed SFU grade 3-4 PUJ obstruction leads to significant improvement of SRF, while delayed pyeloplasty leads to a marginal but, significant loss. This fact should be highlighted to parents so that informed decisions can be made regarding early versus delayed surgery.

Despite the fact that shock-wave lithotripsy (SWL) remains a very good treatment option for smaller stones, it is being challenged by endourologic treatment modalities, which offer similar or even higher success rates in a shorter time, with minimal morbidity and invasiveness. The present study aimed to bring a new and practical insight in order to predict the outcomes of pediatric SWL and to provide objective information about pediatric SWL outcomes. ⋯ In most of the pediatric stone cases, SWL is the first-line treatment option. However, it is wise to define the patients who will benefit the most. Therefore, nomograms can be useful for this purpose. The nomogram in the present study revealed that gender, stone size, number of stones, age, location of the stone, and history of previous intervention were found to be the independent prognostic factors for assessing the stone clearance rates. This nomogram can practically be used to inform the parents, and for proper patient selection for SWL.

Within the chronic medical illness literature, associations exist between caring for an affected child and parent mental health. The few studies examining both mothers and fathers provide mixed results. The purpose of this study is to examine associations between caregiver anxiety, depression, and parenting variables in caregivers of youth with SB as these relate to marital status, age, education, household income, work status, and child's severity of SB. ⋯ Anxiety, depression, and parenting characteristics were differentially impacted by variables such as caregiver and child age, shunt status, and employment status/income for parents of youth with SB. Interventions to improve parenting skills and mental health of these caregivers can be designed to target specific needs of parents. Groups such as the Greater Oklahoma Disabled Sports Association (GODSA) offer real-world support to improve the lives of caregivers of SB children, and should be studied further to optimize outcomes for children.

Observational Study
Autonomic dysreflexia during urodynamics in children and adolescents with spinal cord injury or severe neurologic disease.
Autonomic dysreflexia (AD) is a well-established association of high spinal cord injury (SCI), particularly in those occurring above T6. When a noxious stimulus is encountered, the body responds by stimulating an increase in blood pressure, which is then countered by vasodilation. In patients with autonomic dysreflexia, the patient is unable to vasodilate below the level of spinal injury due to interruption of the autonomic innervation below the injury. This then leads to persistently elevated blood pressure causing uncoordinated autonomic responses such as headache, flushing, sweating, and even hypertensive crisis. The noxious stimulus most commonly reported is bladder or bowel distention [1]. This potential trigger is especially important since many patients with SCI require catheterization and repeated urodynamic testing, both of which predispose them to bladder distention. In response to an incident during which a patient developed severe hypertension during UDS, institutional concern was raised about the potential risk of AD in other patients with SCI ≥ T8 and other severe neurological disease undergoing urodynamic testing, and a protocol was initiated in 2007 for monitoring for AD during UDS. Although no long-term complication was encountered in this incident, the need for improvement in our understanding of the detection and treatment of AD during urodynamic testing was highlighted. However, due to the potential of UDS to trigger AD and possible subsequent severe cardiovascular crisis, a protocol was established at our institution. Because of reports documenting episodes of AD for patients with severe, non-SCI neurologic disease and the unknown risk, these patients also were historically monitored at our institution as well. ⋯ With appropriate monitoring and education, AD is easily recognized and managed conservatively. We found an increased risk of patients developing subsequent AD episodes after an initial episode. Patients who did not have autonomic dysreflexia during initial UDS did not experience autonomic dysreflexia on subsequent UDS. We did not observe autonomic dysreflexia occurring in children with transverse myelitis or encephalomyelitis.
