Background: It is universally agreed that successful and gentle initial bladder closure is decisive for favorable long-term outcome. Due to a number of reasons, including a lack of comparable multicenter studies, there are numerous concepts for initial exstrophy closure.Discussion: Therefore, we describe our concept of delayed, staged reconstruction without osteotomy in classical bladder exstrophy, while taking into considerion the available literature on long-term follow-up as well as on own clinical and research data.Conclusion: Most notably there are multiple medical but also psychological advantages of a delayed procedure. Primary closure without osteotomy is feasible and has no disadvantages in the long-term follow-up when compared to the invasive procedure of osteotomy. Due to high intravesical pressure, initial bladder neck surgery might have negative effects on bladder development and on the upper urinary tract. [ABSTRACT FROM AUTHOR]

Background: Besides physical examination, ultrasonography is the most valuable diagnostic tool to assess the scrotum and testes in the case of an acute scrotum or scrotal pathology.Problems: In infants and toddlers the examination can be challenging. Due to the limited patient compliance, the small testicular size (< 0.5 ml), and low blood flow velocity (< 3 cm/s), it can be difficult to achieve a proper flow curve when assessing blood flow.Conclusion: The examiner's skills are as important as adequate equipment (i. e., linear ultrasound probe, 12-14 MHz) and optimal program settings (Doppler scale < 3 cm/s, gate 1 mm). However, if there is doubt, surgical exploration is unavoidable. [ABSTRACT FROM AUTHOR]

Circumcision and orchidopexy are among the most frequently performed pediatric urological procedures. Although they may be classified as surgical interventions suitable for junior surgeons, either procedure can lead to serious consequences including the loss of the respective organ. In this paper, the general aspects of pediatric urological surgery (e.g., distinctive features of informing underage patients, the handling of children in the operating room, and relevant pediatric anesthesiological aspects) are described first. Then, the most important sources of error will be highlighted and potential complications and their management during all stages of the procedure will be illustrated. Apart from the so-called freehand circumcision, this paper also deals with potential complications when using the Plastibell® device. In regard to orchidopexy, laparoscopic procedure shall be discussed in addition to the standard procedure. [ABSTRACT FROM AUTHOR]

Based on a case report of an intrascrotal lipoblastoma in childhood, we present the preoperative diagnostic algorithm and the main differential diagnoses in testicular and paratesticular tumors as well as their surgical management. An 8-week-old infant was admitted with a scrotal tumor known since birth. MRI showed a pinnate vessel supply, originating in the left internal iliac artery. The tumor was exposed operatively and could be completely removed. Intrascrotal lipoblastoma are rare. Like most testicular and paratesticular tumors in childhood lipoblastomas are benign. Today ultrasound and Doppler sonography are basic tools for diagnosis and surgical planning in testicular and scrotal tumors in childhood. In some cases MRI can provide additional important information for surgical planning. In contrast to adults testis sparing surgery is favoured in children. [ABSTRACT FROM AUTHOR]

Background: In the literature urogenital anomalies are associated with Down syndrome. Anomalies of the external genitals, posterior urethral valves, and renal dys- or hypoplasia are reported. However, the incidence, etiology, and clinical course of neurogenic and functional bladder dysfunction in Down syndrome are unclear.Material and Methods: We report on 23 boys and 1 girl with Down syndrome with a mean age of 79.4 months.Results: Thirteen boys had uni- or bilateral cryptorchidism. Two had posterior urethral valves, two bladder exstrophy, and two hypospadias. Three children had neurogenic and eight non-neurogenic functional bladder dysfunction. Due to loss of renal function nephrectomy was necessary in three patients.Conclusions: Children with Down syndrome seem to often have associated neurogenic or functional bladder dysfunction, which can lead to upper urinary tract deterioration. Therefore, early and regular sonographic and urodynamic evaluation of the bladder function is mandatory. [ABSTRACT FROM AUTHOR]

Balanitis xerotica obliterans (BXO) is a chronic and progressive dermatitis of unknown aetiology and incidence. Its management in childhood is controversial. Although in most cases only the prepuce is affected, meatal and urethral involvement may lead to major surgical reconstruction. Therefore complete surgical excision of the affected skin is considered to be mandatory. In case of involvement, incidental histological evidence or a relapse, or when complete removal of the affected skin is not possible, a topical therapy should be implemented. In a retrospective analysis of our study population (13 children) with BXO, relapse rate was lower after topical therapy with tacrolimus (Protopic), a highly selective immune modulator, than after the standard anti-inflammatory therapy with betamethasone. The use of tacrolimus ointment is a safe therapy with no severe side effects. Due to the fact that there are no predictive factors for progression or relapse of BXO, we consider a topical anti-inflammatory therapy is always indicated after any type of surgery for BXO. Follow-up monitoring should be close, so that any relapse can be detected and treated as early as possible. [ABSTRACT FROM AUTHOR]

While repair of exstrophy has a long tradition in Germany, a comprehensive review of the medical history of exstrophy-epispadias repair and its frequent inconsistencies and setbacks in Germany has not previously been published. Numerous resources were used to collect the information described in this review. Older textbooks from the library of German Society of Urology (DGU) in Düsseldorf and from the School of Medicine Library at the Friedrich-Alexander University in Erlangen were used to collect information on the important steps in the treatment of bladder exstrophy and epispadias from the first report of it onward. A Medline search was done to collect appropriate information from after 1969. Schenck von Grafenberg was the first to describe exstrophy of the bladder, in his report published in 1597, while the term 'exstrophy' was first used by Chaussier in 1780. Isolated epispadias remained unknown and untreated until it was described by Morgagni in 1761. The initial attempts to treat this anomaly were restricted to controlling the incontinence. In 1869 Karl Thiersch described the etiology and anatomy of epispadias and reported on a case of epispadias reconstruction with a long-term follow-up of 11 years. As long ago as in 1897, Mickulicz enlarged a small exstrophic bladder by adding an ilial segment to make it possible to close the bladder. After the first really successful reconstruction of bladder exstrophy in 1942 by Young in the USA, various multiple-stage and single-stage reconstruction approaches emerged in Germany. From the start, urinary diversion was seen as an alternative to reconstruction in the treatment of bladder exstrophy. The first ureterosigmoidostomy was done in an exstrophy patient by Simon in Heidelberg in 1852, after which Maydl described a new technique based on transtrigonal sigmoidostomy for urinary diversion in 1894. There are now three approaches in current use in Germany for the management of bladder exstrophy-epispadias: reconstruction in various staged approaches, complete reconstruction in a single session, and the primary rectal reservoir (Mainz pouch II).

The presumption to suffer from Alzheimer’s disease (AD) accelerates with aging. One important risk factor seems to be the isoform epsilon 4 of the apolipoprotein E gene (Apo ɛ4), which increases the risk to develop AD at an earlier age. Furthermore, convincing evidence is provided that apoptotic cell death mechanisms play an important role in neuronal cell death in AD. In the present study, we investigated whether abnormalities in apoptosis and caspase-3 activity can be found at the level of lymphocytes and a T cell subtype, CD4 T cells, from AD patients compared to aged sex- and ApoE genotype-matched non-demented controls. Under different experimental conditions (at baseline or after in vitro incubation in the presence of proapoptotic stimuli) increased levels of apoptosis and enhanced caspase-3 activity were detected in lymphocytes from AD patients. This difference was most pronounced in the CD4+ T cell subtype. Notably, we found a significant increase of apoptotic cells and caspase-3 activity in lymphocytes from AD patients bearing one or two alleles of the ApoE4 compared to non-E4 carriers. Again, these effects were strongest in CD4+ T cells. Circulating amyloid-beta (Aβ) levels did not differ between AD patients bearing ApoE4 and non-ApoE4 and age-matched controls. Therefore, it is likely that circulating Aβ is not responsible for the observed effects, which might rather reflect an ongoing systemic response in AD, e.g. an increase in CD95 expression.

Renal cell carcinoma (RCC) in childhood is rare and its incidence is estimated to be 3-6% of all kidney cancers in childhood. Thus, clinical experience with renal cell carcinoma in this age group is meager and no consensus between pediatric urologists and pediatric oncologists exists on common treatment strategies. Furthermore, most previous reports included postpubertal patients in whom the biological behavior of the RCC and treatment options are the same as in adults. Based on the literature and a clinical case report of a 12-year-old boy suffering from a papillary renal cell carcinoma stage IV (pT2 N2 MO), the relevance of the biological behavior of different histological subtypes and their treatment options are reviewed and discussed. In adulthood lymph node dissection is still controversial, but in children it seems to have a positive effect on survival. Immunotherapy in childhood is still and experimental option and just a few cases are reported in the literature. [ABSTRACT FROM AUTHOR]

Introduction: The aim of this study was to compare total intravenous anaesthesia (TIVA) using propofol and remifentanil (P/R-group) and balanced anaesthesia (BA) using sevoflurane and remifentanil (S/R-group) for paediatric surgery.Patients and Methods: A total of 120 patients aged 6 months to 16 years scheduled for elective minor lower abdominal surgery were randomly assigned to receive either propofol (5-10 mg/kg/h) and remifentanil (0.125-1.0 microgram/kg/min) or sevoflurane (1.0-1.5 MAC) and remifentanil (0.125-1.0 microgram/kg/min). Perioperative haemodynamics as well as recovery and discharge times, PONV and side-effects were studied. The patients vigilance, comfort and pain intensity were assessed postoperatively using the objective pain discomfort scale, the Steward post-anaesthetic recovery score and a visual analogue scale.Results: Postoperative recovery (9.0 vs 11.6 min) and extubation times (11.8 vs. 15.0 min) as well as the time taken until a Steward post-anaesthetic recovery score > 3/4 (15.2 vs. 21.4 min) was reached were significantly shorter in the P/R-group. However, the length of time until discharge to the ward, postoperative comfort, pain intensity and analgesic requirements as well as PONV were comparable in both groups.Conclusions: With regards to the investigated parameters, TIVA with propofol and remifentanil is equally effective as BA with sevoflurane and remifentanil in paediatric patients. However, considering the selected dosing regimen, recovery times were significantly shorter for children after TIVA. [ABSTRACT FROM AUTHOR]

In total urethral diverticula in children represent a very rare urological disorder. Primary localisation is the dorsal side of the urethra, ventral located diverticula are extremely rare. We report on a ten year old girl with a ventral, urethral diverticulum presenting with the symptoms of persisting enuresis. The diverticulum was excised through a median laparatomy. Placement of suprapubic catheter facilitated adequate postoperative drainage and postoperative cystourethrography confirmed the absence of extravasation. [ABSTRACT FROM AUTHOR]

Urethral duplication is a rare congenital anomaly with variable clinical presentation. A number of theories have been proposed to describe the embryology of the condition; the actual mechanism of the disorder is still unclear. We present a 2-year-old boy with complete urethral duplication and two functional sphincters. Functional and surgical results were satisfying with good continence. [ABSTRACT FROM AUTHOR]

Infectious conditions of the infantile genitals are a diagnostic challenge. One of the rare differential diagnoses is lymphocytoma cutis benigna. We report a case of borrelial lymphocytoma of the glans penis in a 9 year old boy. Based on this case, the clinical, diagnostic and therapeutic aspects of this rare form of dermatoborreliosis are discussed. [ABSTRACT FROM AUTHOR]
