High spatial correlation in brain connectivity between micturition and resting states within bladder-related networks using 7 T MRI in multiple sclerosis women with voiding dysfunction.

BACKGROUND: Several studies have reported brain activations and functional connectivity (FC) during micturition using functional magnetic resonance imaging (fMRI) and concurrent urodynamics (UDS) testing. However, due to the invasive nature of UDS procedure, non-invasive resting-state fMRI is being explored as a potential alternative. The purpose of this study is to evaluate the feasibility of utilizing resting states as a non-invasive alternative for investigating the bladder-related networks in the brain. METHODS: We quantitatively compared FC in brain regions belonging to the bladder-related network during the following states: 'strong desire to void', 'voiding initiation (or attempt at voiding initiation)', and 'voiding (or continued attempt of voiding)' with FC during rest in nine multiple sclerosis women with voiding dysfunction using fMRI data acquired at 7 T and 3 T. RESULTS: The inter-subject correlation analysis showed that voiding (or continued attempt of voiding) is achieved through similar network connections in all subjects. The task-based bladder-related network closely resembles the resting-state intrinsic network only during voiding (or continued attempt of voiding) process but not at other states. CONCLUSION: Resting states fMRI can be potentially utilized to accurately reflect the voiding (or continued attempt of voiding) network. Concurrent UDS testing is still necessary for studying the effects of strong desire to void and initiation of voiding (or attempt at initiation of voiding).

Disfunción miccional en el adulto. Un artículo docente / Voiding dysfunction in the adult. A teaching article

Voiding dysfunction is defined as an abnormally slow and/or incomplete micturition, and can be divided in bladder outlet obstruction (BOO) and detrusor underactivity (or hypocontractility). BOO is characterized by reduced urine flow rate and increased detrusor pressure, and can be of anatomical or functional origin. Detrusor underactivity encompasses a reduced urine flow rate associated to low pressure and/or poorly sustained detrusor contraction, and its etiology is multifactorial. Lower urinary tract symptoms are classified as storage, voiding and post micturition symptoms, may be objectively quantified with specific questionnaires, and don't correlate properly with voiding dysfunction. Patients' evaluation requires a directed physical examination of the abdomen, pelvis and genitals focused to detect anatomical and neurological abnormalities. Voiding dysfunction can be demonstrated non-invasively using uroflowmetry and pelvic ultrasound. Uroflowmetry allows determining urinary flow characteristics and their most important parameters are voided volume, maximum flow rate and shape of the curve. Pelvic ultrasound permits to estimate prostatic size and post void residual, suspect detrusor hypertrophy (due to BOO) and detect bladder stones. Invasive test must be reserved for special cases of confirmed voiding dysfunction: cystoscopy when there is concomitant hematuria, urethrocystography to study urethral stenosis and urodynamics to differentiate BOO from detrusor underactivity.

Anterior bladder wall thickness, post-void urine residue, and bladder emptying efficiency as indicators of bladder dysfunction in Nigerian men with benign prostatic hyperplasia.

BACKGROUND: Benign Prostatic Hypertrophy [BPH] is associated with voiding dysfunctions. Urodynamic study is the gold standard for diagnosis of voiding dysfunctions but is invasive. Bladder wall thickness (BWT), post-void urine residue (PVR), and bladder emptying efficiency (BEE) are noninvasive predictors of voiding dysfunction. OBJECTIVE: To study the relationship among BWT, PVR, and BEE in BPH. SUBJECTS AND METHODS: A hospital-based cross-sectional prospective study of new BPH patients at Nnamdi Azikiwe University Teaching Hospital, Nnewi. The participants had abdominal ultrasonography measurement of anterior BWT (at bladder volume ≥200 mls), prostate volume (PV), and PVR using Prosound SSD3500 (Aloka Co Ltd, Tokyo, Japan) with an abdominal probe frequency of 3.5 MHz. Then the BEE was calculated. The anterior BWT was divided into two groups: <5 mm and ≥5 mm. The data were analyzed using SPSS version 20. Pearson's correlation was used to assess correlation and the differences between the means of the two groups of BWT were compared by Mann-Whitney test. A P- Value <0.05 was considered significant. RESULTS: Seventy seven men with a mean age of 66.66 ± 10.74 years were included in the study. Sixty one percent had symptoms lasting >12 months. The average anterior BWT, PBV, PVR, BEE, PV, and PSA were 4.55 ± 1.02 mm, 260.98 ± 57.44 mls, 58.36 ± 52.94 mls, 77.98 ± 17.37%, 66.31 ± 46.38 mls, and 8.04 ± 5.97 ng/ml, respectively. There was a significant positive correlation between BWT and duration of symptoms (P = 0.044) and a significant negative correlation between BWT and BEE (P = 0.005). An insignificant positive correlation was found between BWT and PVR (P = 0.255). Fifty four (70.1%) had BWT <5 mm and 29.9% had BWT ≥5 mm. The mean IPSS (P = 0.000), PV (P = 0.032) and PVR (P = 0.020) were significantly higher in the ≥5 mm group. The ≥5 mm group also had a significantly lower BEE (P = 0.002). CONCLUSION: Voiding dysfunction was more severe in patients with BWT of 5 mm or more. There was a positive, but insignificant, correlation between anterior BWT and PVR and a significant negative correlation between BWT and BEE.

Urethral Catheter Induced Huge Anterior Urethral Diverticulum.

We report a 22-year old gentleman who presented with postmicturition urinary dribbling for nearly 1 year along with urinary urgency and frequency. He had a history of brain tuberculosis 2 years back and was hospitalized for 4 months with a urethral catheter. Examination revealed a 3 cm cystic swelling in the penoscrotal junction. On pressing the sac, a gush of urine came out through the urethral meatus. A micturating cystourethrogram revealed a huge anterior urethral diverticulum. Cystoscopic assessment also confirmed the diagnosis and demonstrated transillumination. He subsequently underwent surgical excision of the diverticulum and is doing well on follow-up.

MRI of the Male Pelvic Floor.

The pelvic floor is a complex structure that supports the pelvic organs and provides resting tone and voluntary control of the urethral and anal sphincters. Dysfunction of or injury to the pelvic floor can lead to gastrointestinal, urinary, and sexual dysfunction. The prevalence of pelvic floor disorders is much lower in men than in women, and because of this, the majority of the published literature pertaining to MRI of the pelvic floor is oriented toward evaluation of the female pelvic floor. The male pelvic floor has sex-specific differences in anatomy and pathophysiologic disorders. Despite these differences, static and dynamic MRI features of these disorders, specifically gastrointestinal disorders, are similar in both sexes. MRI and MR defecography can be used to evaluate anorectal disorders related to the pelvic floor. MRI can also be used after prostatectomy to help predict the risk of postsurgical incontinence, to evaluate postsurgical function by using dynamic voiding MR cystourethrography, and subsequently, to assess causes of incontinence treatment failure. Increased tone of the pelvic musculature in men secondary to chronic pain can lead to sexual dysfunction. This article reviews normal male pelvic floor anatomy and how it differs from the female pelvis; MRI techniques for imaging the male pelvis; and urinary, gastrointestinal, and sexual conditions related to abnormalities of pelvic floor structures in men.Online supplemental material is available for this article.©RSNA, 2019.

Effect of Prenatal Repair of Myelomeningocele on Urological Outcomes at School Age.

PURPOSE: We investigated longer term urological outcomes in patients enrolled in the Management of Myelomeningocele Study (MOMS). MATERIALS AND METHODS: Women who participated in the original trial were asked for consent for followup for their child at age 6 years or older in a single comprehensive study visit to a MOMS center. Participating children underwent urological and radiologic procedures to provide objective evidence of current bladder functioning. Primary urological outcome was defined as any among need for clean intermittent catheterization, vesicostomy, urethral dilatation or augmentation cystoplasty. RESULTS: A total of 156 children were evaluated, with a mean age of 7.4 years. Overall 62% vs 87% in the prenatal and postnatal surgery groups, respectively, were placed on clean intermittent catheterization (RR 0.71, 95% CI 0.58-0.86, p <0.001). Voiding status was significantly different between the groups (p <0.001) as 24% in the prenatal group vs 4% in the postnatal group (RR 5.8, 95% CI 1.8-18.7) were reported to be voiding volitionally. Augmentation cystoplasty, vesicostomy and urethral dilation did not differ between the 2 groups. Aside from a larger post-void residual urodynamic catheterization volume, there were no other statistical differences in videourodynamic data or findings on renal/bladder ultrasound. CONCLUSIONS: Prenatal closure of myelomeningocele resulted in less reported clean intermittent catheterization at school age and the mechanism for this is unclear. Although most children are in diapers or on clean intermittent catheterization, parental reports showed children who underwent prenatal closure may be more likely to void volitionally than the postnatal group. Despite these findings, urological outcomes alone should not be the sole impetus to perform in utero closure in children with spina bifida.

Similarity of functional connectivity patterns in patients with multiple sclerosis who void spontaneously versus patients with voiding dysfunction.

AIM: To investigate if Multiple Sclerosis (MS) lesion characteristics affect functional brain connectivity (FC) during bladder voiding. METHODS: Twenty-seven ambulatory female patients with MS completed our functional magnetic resonance imaging (fMRI)/urodynamic testing (UDS) platform. Individual fMRI activation maps were generated at initiation of voiding. FC patterns of these regions were calculated and compared. Similarity of the FC pattern from one patient relative to all others was expressed by a parameter FC_sim. A statistical analysis was performed to reveal the relationship of the existence of an enhancing brain lesion, the size of the largest lesion and the ability to void spontaneously to this FC similarity measure. RESULTS: FC_sim values were significantly lower for patients with an enhancing MS lesion (11.7 ± 3.1 vs 5.3 ± 2.1 P < 0.001). Lesion size smaller than 20 mm inversely correlated significantly with FC_sim (R = -0.43, P = 0.05). Patients with the ability to void spontaneously had a higher FC_sim value (12.0 ± 2.8 vs 9.3 ± 4.4 s, P = 0.08). Patients that exhibited a decrease of compliance also showed a significantly lower FC_sim value (11.3 ± 3.5 vs 4.7 ± 0.7, P < 1e-5). CONCLUSION: FC connectivity analysis derived from an fMRI task-based study including repetitive voiding cycles is able to quantify the heterogeneity of connectivity patterns in the brain of MS patients. FC similarity decreased with maximum lesion size or the presence of enhancing lesions affecting the ability to void spontaneously.

Two cases of sporadic adult-onset neuronal intranuclear inclusion disease preceded by urinary disturbance for many years.

Neuronal intranuclear inclusion disease (NIID) is a neurodegenerative disease defined by the presence of eosinophilic hyaline intranuclear inclusions. The initial and main clinical feature of adult-onset NIID is predominantly dementia. We present herein 2 cases of sporadic adult-onset NIID with longstanding urinary disturbance prior to development of other neurological symptoms. Case 1: A 71-year-old woman was admitted after she lost consciousness while bathing. She presented slowly progressive bladder dysfunction starting at the age of 40. Recently, she complained of recurrent light-headedness on standing. Her neurological findings showed miosis, muscle weakness, rigidity, hyporeflexia, sensory disturbance, cerebellar ataxia, and orthostatic hypotension. Case 2: A 68-year-old man was admitted because of episodes of transient loss of consciousness. Ten years earlier, he had developed urinary dysfunction. His neurological findings revealed cognitive dysfunction, cerebellar ataxia, and hyporeflexia. Both patients had leukoencephalopathy and motor-sensory neuropathy. In both cases, diffusion-weighted imaging showed high-intensity signals in the corticomedurally junction; and skin biopsy samples revealed ubiquitin-positive intranuclear inclusions. Therefore, we made a diagnosis of adult-onset NIID. Although numerous cases of this disorder have been reported in the past, there were only a few cases showing the development of other neurological symptoms after longstanding urinary disturbance. Our cases suggest that it is worthwhile considering the possibility of NIID in cases with a long-term history of neurogenic bladder dysfunction.

Videourodinamia con cistosonografía para estudio de la disfunción miccional y otras uropatías en niños / No disponible

Objetivos: Valorar la utilidad de una nueva modalidad de videourodinamia sin radiaciones ionizantes en el estudio de disfunciones miccionales y otras uropatías en niños, sustituyendo cistouretrografía miccional seriada por cistosonografía o urosonografía miccional. Material y métodos: Estudio prospectivo con realización simultánea de cistomanometría de llenado y cistosonografía en 43 niños durante los dos últimos años. El contraste sonográfico fue infundido a través del catéter de urodinamia. Resultados: 18 niñas y 25 niños, con edades de entre 2 meses y 14 años (media de 6,18 años). La indicación más frecuente en los varones fue disfunción miccional y en las niñas seguimiento de reflujo. El 60,5% presentaba alteraciones urodinámicas, predominando baja acomodación vesical (N = 9), hiperactividad del detrusor mixta (N = 5) y disinergia vésico-esfinteriana (N = 4). 15 niños tenían reflujo: 8 pasivos, 5 activos (asociados a actividad contráctil del detrusor o en fase miccional) y dos mixtos. Se vio patología uretral en dos varones (valvas de uretra posterior y estenosis uretral) y dos niñas (uretra en peonza). Se encontró relación estadísticamente significativa entre presencia de reflujo vesicoureteral y otras variables: capacidad vesical (t = 4,98; p < 0,005), actividad del detrusor (t = 3; p = 0,005), sexo (t = 2,553; p = 0,015) y residuo postmiccional alto (t = 3,75; p < 0,005), siendo más frecuente en niñas con vejigas grandes, con actividad del detrusor y residuo postmiccional alto. Conclusiones: La UMS puede sustituir a la cistouretrografía convencional como prueba de imagen asociada a la urodinamia. Con este tipo de exploración hemos podido indicar un tratamiento a nuestros pacientes, sometiéndolos a un único sondaje y sin exponerlos a radiaciones ionizantes

Objectives: To assess the utility of a new modality of video-urodynamic for study of lower urinary tract dysfunction and other uropathies in kids, replacing voiding cystourethrography by echo-enhanced cystosonography, without ionizing radiations. Material and methods: prospective study with simultaneous performance of filling cystometry and cystosonography in 43 kids during the last two years. The sonographic contrast was infused trough the urodynamic catheter. Results: 18 girls and 25 boys, with an average age of 6.18 years (between 2 months and 14 years). The most frequent indication was micturition disfunction in boys and vesicoureteral reflux follow-up in girls. 60,5% presented urodynamic alterations, predominating low bladder accommodations (N = 9), mixed detrusor overactivity (N = 5) and bladder sphincter dyssynergia (N = 4). 15 children had vesicoureteral reflux: 8 passive, 5 active (associated with contractile activity of the detrusor or in the voiding phase) and two mixed. Urethral pathology was seen in two males (urethral valves and stenosis) and two girls (spinning top urethra). A statistically significant relationship was found between the presence of vesicoureteral reflux and other variables: bladder capacity (t = 4.98; p < 0.005), detrusor activity (t = 3; p = 0.005), sex (t = 2.543; p = 0.015) and high post-void residual volume (t = 3.75; p < 0.005), so that it was more frequent in girls with big bladders, with detrusor activity and high post-void residue. Conclusions: Cystosonography can replace conventional cystourethrography as an imaging test associated with urodynamics. With this type of exploration we have been able to indicate the treatment to our patients, subjecting them to a single catheterization and without exposing them to ionizing radiation

[Ultrasonography of the lower urethra in male sheep lambs]. / Sonographische Darstellung der distalen Harnröhre beim männlichen Schaflamm.

In male small ruminants, voiding disturbances are not uncommon. A precise knowledge of the underlying disease is essential for prognostic evaluation as well as for a decision concerning the therapeutic approach. Common reasons for voiding disturbances in the male small ruminant are obstructive urolithiasis, traumata of the penis or inflammatory processes within the urethra or urinary bladder. The diagnostic method of choice - in addition to clinical examination - is diagnostic imaging. Because radiology is not always possible under field conditions, the aim of this article is a detailed presentation of ultrasonography of the distal urethra of the male lamb.

The Association of Congenital Urethral Duplication and Double Megalourethra.

BACKGROUND: Urethral duplication and megalourethra are rare urethral anomalies. However, the concomitance of urethral duplication and double megalourethra has not been reported previously. CASE REPORT: A newborn was presented with penile swelling during voiding. Physical examination revealed a retractable foreskin and two external meatus of a double urethra. Retrograde urethrography demonstrated two complete megalourethras. Urethro-urethrostomy and urethroplasty were performed when the patient was 10 months old. The patient was followed up for one year without any urinary problems and has good cosmetics and urinary continence. CONCLUSION: The concomitance of these two rare anomalies and more importantly its surgical treatment makes this case report unique and valuable.

Rentabilidad diagnóstica de la resonancia magnética lumbosacra solicitada desde las consultas de urología pediátrica / Diagnostic yield of lumbosacral magnetic resonance imaging requested by paediatric urology consultations

Objetivos: En series históricas, la rentabilidad diagnóstica de la resonancia magnética lumbosacra para descartar disrafismo espinal oculto (o mielodisplasia oculta), solicitada desde urología pediátrica oscila entre el 2 y 15%. El objetivo del estudio es definir nuestra rentabilidad en niños con síntomas miccionales, y definir variables que aumenten la posibilidad de encontrar disrafismo espinal oculto. Pacientes y métodos: Selección de pacientes con disfunciones miccionales a los que se solicitó resonancia magnética desde las consultas de urología pediátrica, por persistencia de síntomas tras tratamiento, disfunción de vaciado, o por otros hallazgos clínicos o urodinámicos. Se analizaron variables clínicas (ITU, fugas diurnas, enuresis, disfunción de vaciado, urgencia, ecografía renal, radiografía lumbosacra, antecedentes de retención aguda de orina, estigmas cutáneos, mialgias) y urodinámicas (hiperactividad o arreflexia, micción disfuncional, patrón interrumpido, valor de acomodación y flujo máximo). Análisis univariante con SPSS 20.0 Resultados: Analizamos a 21 pacientes en el periodo 2011-2015. Mediana de edad: 6 años (3-10). Tres pacientes (14,3%) presentaron disrafismo espinal oculto: un lipoma raquídeo, un filum lipomatoso y un síndrome de regresión caudal con estenosis de canal. Las variables con diferencia estadísticamente significativa fueron las mialgias y el antecedente de retención aguda de orina (66,7 vs. 5,6%; p = 0,04; OR = 34; IC95%: 1,5-781 para ambas variables). Conclusiones: La rentabilidad diagnóstica de la resonancia magnética solicitada a niños con disfunciones miccionales sin estigmas cutáneos ni alteraciones neuroortopédicas es baja, aunque no desdeñable. En este grupo, los pacientes con antecedentes de retención aguda de orina y/dolor muscular (dolor, «calambres») pueden presentar una rentabilidad diagnóstica o valor predictivo positivo mayor

Objectives: In the historical series, the diagnostic yield of lumbosacral magnetic resonance imaging to rule out occult spinal dysraphism (or occult myelodysplasia), requested by paediatric urology, ranged from 2% to 15%. The aim of this study was to define our cost-effectiveness in children with urinary symptoms and to define endpoints that increase the possibility of finding occult spinal dysraphism. Patients and methods: A screening was conducted on patients with urinary dysfunction for whom an magnetic resonance imaging was requested by the paediatric urology clinic, for persistent symptoms after treatment, voiding dysfunction or other clinical or urodynamic findings. We analysed clinical (UTI, daytime leaks, enuresis, voiding dysfunction, urgency, renal ultrasonography, lumbosacral radiography, history of acute urine retention, skin stigma and myalgia) and urodynamic endpoints (hyperactivity or areflexia, voiding dysfunction, interrupted pattern, accommodation value and maximum flow). A univariate analysis was conducted with SPSS 20.0. Results: We analysed 21 patients during the period 2011-2015. The median age was 6 years (3-10). Three patients (14.3%) had occult spinal dysraphism: one spinal lipoma, one filum lipomatosus and one caudal regression syndrome with channel stenosis. The endpoints with statistically significant differences were the myalgias and the history of acute urine retention (66.7% vs. 5.6%, P = .04; OR = 34; 95%CI: 1.5-781 for both endpoints). Conclusions: The diagnostic yield of magnetic resonance imaging requested for children with urinary dysfunctions without skin stigma or neuro-orthopaedic abnormalities is low, although nonnegligible. In this group, the patients with a history of acute urine retention and muscle pain (pain, «cramps») can experience a greater diagnostic yield or positive predictive value

Videourodynamic Studies of Women with Voiding Dysfunction.

This retrospective study is aimed to present videourodynamic findings of women with symptoms of voiding dysfunction in a medical center. Of 1914 women, the diagnoses included bladder outlet obstruction (BOO, n = 810, 42.3%), bladder dysfunction (n = 1,048, 54.8%) and normal tracings (n = 56, 2.9%). Anatomic BOO (n = 49) included cystocele (n = 19) and urethral stricture (n = 30). Common functional BOOs included dysfunctional voiding (n = 325, 17.0%) and poor relaxation of the external sphincter (n = 336, 17.6%). Common bladder dysfunction subtypes included detrusor underactivity (n = 337, 17.6%), detrusor hyperactivity with impaired contractility (n = 231, 12.1%), and bladder oversensitivity (n = 325, 17.0%). Receiver operating characteristic (ROC) analysis were performed, and the following optimum cutoff values were determined: (1) voiding detrusor pressure at a maximum flow rate (Pdet.Qmax) = 30 cmH2O for differentiating BOO from bladder dysfunction and normal tracings, with an ROC area of 0.78; (2) the Abrams-Griffiths number = 30 for differentiating anatomic from functional BOO, with an ROC area of 0.66; (3) post-void residual = 200 mL for differentiating bladder neck dysfunction from the other BOOs, with an ROC area of 0.69; (4) Pdet.Qmax = 30 cmH2O for differentiating dysfunctional voiding from poor relaxation of the external sphincter with an ROC area of 0.93. The above findings can be used as initial guide for management of female BOO.

Do we assess urethral function adequately in LUTD and NLUTD? ICI-RS 2015.

INTRODUCTION: Urethral function, as well as anatomy, play a significant role in voiding reflex and abnormalities in one or both contribute to the pathophysiology of Lower Urinary Tract Dysfunction (LUTD). We have several diagnostic tools to assess the urethral function or dysfunction but the question remains, are these adequate? METHODS: This is a report of the proceedings of Think Tank P1: 'Do we assess urethral function adequately in LUTD and NLUTD?' from the annual International Consultation on Incontinence-Research Society, which took place September 22-24, 2014 in Bristol, UK. RESULTS: We have collected and discussed, as a committee, the evidence with regard to the urethra and the available relevant methods of testing urethral function, with the emphasis on female and male voiding dysfunction. We looked into previous research and clinical studies and compiled summaries of pertinent testing related to urethral function. The discussion has focused on clinical applications and the desirability of further development of functional tests and analyses in this field. CONCLUSIONS: There are limitations to most of the urethral function tests. Future perspectives and research should concentrate on further development of functional testing and imaging techniques with emphasis on standardization and clinical application of these tests.

Establishing a Standard Protocol for the Voiding Cystourethrography.

The voiding cystourethrogram (VCUG) is a frequently performed test to diagnose a variety of urologic conditions, such as vesicoureteral reflux. The test results determine whether continued observation or an interventional procedure is indicated. VCUGs are ordered by many specialists and primary care providers, including pediatricians, family practitioners, nephrologists, hospitalists, emergency department physicians, and urologists. Current protocols for performing and interpreting a VCUG are based on the International Reflux Study in 1985. However, more recent information provided by many national and international institutions suggests a need to refine those recommendations. The lead author of the 1985 study, R.L. Lebowitz, agreed to and participated in the current protocol. In addition, a recent survey directed to the chairpersons of pediatric radiology of 65 children's hospitals throughout the United States and Canada showed that VCUG protocols vary substantially. Recent guidelines from the American Academy of Pediatrics (AAP) recommend a VCUG for children between 2 and 24 months of age with urinary tract infections but did not specify how this test should be performed. To improve patient safety and to standardize the data obtained when a VCUG is performed, the AAP Section on Radiology and the AAP Section on Urology initiated the current VCUG protocol to create a consensus on how to perform this test.

An Aggressive Retroperitoneal Fibromatosis.

INTRODUCTION: Aggressive fibromatosis (AF) is a heterogeneous group of mesenchymal tumors that have locally infiltrative growth and a tendency to relapse. The clinical picture is often conditioned by the obstruction of the ureter or small intestine. Diagnosis is based on clinical, radiological and histological parameters. A CASE REPORT: We report a case of male patient, aged 35 years, with the retroperitoneal fibromatosis. He reported to the physician because of frequent urination with the feeling of pressure and pain. Computed tomography revealed the tumor mass on the front wall of the bladder with diameter of 70mm with signs of infiltration of the musculature of the anterior abdominal wall. Endoscopic transurethral biopsy showed proliferative lesion binders by type of fibromatosis. The tumor was surgically removed in a classical way. The patient feels well and has no recurrence thirty-six months after the operative procedure. CONCLUSION: The complete tumor resection is the therapeutic choice for the primary tumor as well as for a relapse.

Distress experienced during pediatric VCUGs - a granular, prospective assessment using the brief behavioral distress scale.

BACKGROUND: In spite of decades of experience with the procedure, controversy persists as to the overall distress experienced by children and the routine need for sedation in children undergoing voiding cystourethrograms (VCUG). Many studies have attempted to address these issues, often divided into one camp that champions routine sedation while another group believes that pretest preparation is often all that is needed. At the root of these issues are some of the limitations of previous studies as most incorporate inherently subjective parental questionnaires to determine distress levels rather than using an objective, unbiased observer. OBJECTIVE: The objective of this study is to use a validated and reliable tool (the brief behavioral distress scale) to objectively evaluate the distress experienced during VCUGs. MATERIALS AND METHODS: A prospective study of 26 children (ages 3-7 years old) was performed by the pediatric radiology department at a large urban academic medical center. Patients were evaluated for distress during 12 separate VCUG steps beginning with the patient entering the room and ending with the clothing being replaced at study completion. RESULTS: Using a general linear model (repeated measures analysis of variance (ANOVA)), significant distress was identified during two phases of the examination, catheter insertion (P-values ranging <0.001-0.19) and the full bladder phase (P-values ranging 0.005-0.043). The mean distress score for catheter insertion (mean: 1.38, standard deviation [SD]: 1.098) was nearly three times higher than the next most distressful step, i.e. full bladder (mean: 0.65, SD: 0.745). Additionally, entering the room was perceived as significantly more distressing than the catheter out (P = 0.016) and clothing replacement phase (P = 0.006). CONCLUSION: We find that despite there being significantly increased distress during the catheter insertion and full bladder phases, the distress levels during VCUGs are markedly less than in previous reports. Even the most distressful stage, catheterization, was less stressful than previously reported with levels closer to that of minor distress evinced by comfort-seeking behavior from a parent rather than more significant distress resulting in screaming. Our findings corroborate and expand on the conclusion of the effectiveness of pretest preparation and child life specialist involvement.
