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.

Comparative Study
Current diagnosis and management of primary isolated bladder diverticula in children.
Primary isolated bladder diverticula (PIBD) that are not correlated with the UVJ comprise approximately 10% of all primary bladder diverticulas (PBDs). No guidelines have been established for PIBD repair. It is unknown if infections or voiding dysfunction are impacted by the size of diverticula. ⋯ PIBD of >3 cm is characterized by UTI development, functional lower urinary tract symptoms, and disorders of bladder storage or emptying. Surgical repair of these diverticula is associated with improvement of voiding dysfunction and elimination of UTIs.

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.
