Microduplications At 22q11.21 are Associated with Classic Bladder Exstrophy

2010

Purpose Classic exstrophy of the bladder (CBE) is part of the exstrophy-epispadias complex (EEC), a spectrum of urogenital anomalies in which part or all of the distal urinary tract fails to close. Familial occurrence has been observed, and previous studies have suggested an underlying multifactorial mode of inheritance. To date, no causative genetic or non-genetic factor has been unequivocally identified in humans. The present study aimed to identify microaberrations characterized by loss or gain of genomic material that contribute to the EEC at a genome-wide level. Material and Methods Molecular karyotyping, utilizing 549,839 single nucleotide polymorphisms (SNPs) with an average spacing …

How to Name Papillary Tumors of the Bladder in Children: Transitional Cell Carcinoma or Papillary Urothelial Neoplasm of Low Malignant Potential?

2015

Urinary bladder malignancies are uncommon in children. Approximately 80 children with papillary carcinoma have been described to date, presenting as papillary neoplasms of both low grade and low stage. On the basis of the 1973 World Health Organization classification, tumors were classified as transitional cell carcinoma of the urinary bladder (TCCB). Owing to more detailed histologic criteria, this term has been replaced by papillary urothelial neoplasm of low malignant potential and low-grade carcinoma of the urinary bladder in the World Health Organization-International Society of Urologic Pathology consensus classification system of urothelial neoplasms 2004. Nevertheless, TCCB still re…

Confocal Laser Endomicroscopy and Chromoendoscopy - A New Option of Surveillance in Patients with Ureterosigmoidostomy or Rectosigmoid Pouch

2010

Purpose In patients with bladder exstrophy-epispadias-complex (BEEC) or in selected patients with bladder loss for other reasons, ureterosigmoidostomy (USIG) & rectosigmoid pouch (Mainz Pouch (MZP) II) has been used at our institution. This diversion carries a lifelong risk for secondary malignancies. Therefore annual colonoscopy is recommended. Identification of potentially malignant structures can be challenging, and biopsies are taken in doubt, with the risk of injuring the ureterocolic implantation site. Using confocal laser endomicroscopy (CLE) and chromoendoscopy, the uretero-intestinal anastomosis is better visualized compared to conventional colonoscopy, and target biopsies could be…

Turning a new “page”: ways to decrease the number of pages after hours without compromising patient care

2020

Pages to house staff after hours, especially overnight, lead to interrupted sleep and fatigue the next day. Although some pages are urgent, others may not need an immediate response. In this study we aimed to identify unwarranted pages and to establish ways to reduce them.Over 2 months, all pages to the Department of Pediatric Urology at the Hospital for Sick Children in Toronto, Canada, during call hours were documented, including the assessment of the responding physicians of their medical necessity. After analyzing the reasons for inappropriate pages, we took several steps to try to reduce them without impairing patient care. One year later, pages were tracked again to evaluate the effic…

Microduplications at 22q11.21 are associated with non-syndromic classic bladder exstrophy

2009

The exstrophy-epispadias complex (EEC) comprises a spectrum of urogenital anomalies in which part or all of the distal urinary tract fails to close. The present study aimed to identify microaberrations characterized by loss or gain of genomic material that contribute to the EEC at a genome-wide level. Molecular karyotyping, utilizing 549,839 single nucleotide polymorphisms (SNPs) with an average spacing of 5.7 kilobases, was performed to screen an initial cohort of 16 patients with non-syndromic EEC. A de novo microduplication involving chromosomal region 22q11.21 was identified in one patient with classic exstrophy of the bladder (CBE). Subsequent multiplex ligation-dependent probe amplifi…

Bladder augmentation and urinary diversion in patients with neurogenic bladder: Non-surgical considerations

2011

Segments from almost all parts of the bowel have been used for urinary diversion. As a result, the available absorptive surface area of the bowel is reduced, and the incorporation of bowel segments into the urinary tract may have metabolic consequences. This is an area somewhat neglected in the literature. Metabolic complications are rare, but sub-clinical metabolic disturbances are quite common. Several studies have demonstrated that some of the absorbent and secreting properties of the bowel tissue are preserved after incorporation into the urinary tract. Hyperchloraemic metabolic acidosis can occur if ileal and/or colon segments are used, as well as malabsorption of vitamin B(12) and bil…

Effect of chronic bladder outlet obstruction on blood flow of the rabbit bladder.

2001

Previous studies have shown that the initial reaction of the rabbit bladder to partial bladder outlet obstruction is increased blood flow at day 1 and a return to baseline blood flow at 1 week. Mucosal and muscle blood flow followed this pattern but mucosal blood flow was always 4 to 5-fold greater. In this study we examined the effect of 4 weeks of outlet obstruction on bladder blood flow and correlated it with the severity of bladder contractile dysfunction.A total of 14 male New Zealand White rabbits underwent partial outlet obstruction creation by standard methods. After 4 weeks the rabbits were anesthetized, and blood flow to the muscle and mucosa was determined by standard fluorescent…

Vitamin B12 Deficiency in Children after Continent Urinary Diversion by Mainz Pouch Technique

2010

Purpose MAINZ pouch I urinary diversion provides a high-capacity, low-pressure reservoir. The use of terminal ileum can cause a decrease of vitamin B12 levels. Symptoms caused by vitamin B12 deficiency are rare, but some are irreversible, therefore annual check-ups are recommended. In this study the vitamin B12 levels in the above patients were analyzed in retrospect. Material and Methods The ileocecal segment was used for urinary tract reconstruction in > 80 children ≤17 years of age. B12 levels were determined at various time points within up to 21 years after surgery in 63 patients (8 with ileocecal bladder substitution, 55 continent cutaneous diversion). B12 values below 200pg/ml were c…

Aspirin treatment improves bladder function after outlet obstruction in rabbits.

2001

Abstract Objectives. To examine whether bladder smooth muscle dysfunction after outlet obstruction could be altered by treatment with aspirin. Long-term outlet obstruction causes contractile and metabolic dysfunction of the bladder in vivo and in vitro. The evidence is growing that a decrease in bladder perfusion is an important cause of this phenomenon. The platelet aggregation inhibitor, acetylsalicylic acid (aspirin), has been used to improve perfusion of the heart for decades. Methods. Ten male New Zealand white rabbits were obstructed for 4 weeks. Five rabbits received no further treatment (Obs), and 5 rabbits received 2 mg/kg/day aspirin (Obs+aspirin), administered by an osmotic pump …

Absorption of oxybutynin from vaginal inserts: drug blood levels and the response of the rabbit bladder.

2000

Abstract Objectives. Oxybutynin has been used for treatment of urge urinary incontinence for more than 20 years. However, one of the major problems with its use is uncomfortable anticholinergic side effects that can lead to discontinuation of treatment. Alternative forms of drug administration may reduce side effects and thus improve patient compliance. Methods. A cylinder-shaped, curved silicone elastomer insert containing oxybutynin was anchored in the vagina of female rabbits. The inserts were designed to release oxybutynin at rates of 0.5, 1.0, and 5.0 mg/day, respectively. Blood drug and metabolite levels were monitored for 1 to 7 days and cystometry was carried out after 7 days of tre…

Retroperitoneal neuroblastomas - a single institution experience in 90 patients

2007

Purpose Nowadays neuroblastomas are detected incidentally by ultrasound in early stages. Primary surgery, chemotherapy and/or radiotherapy are treatment options. However, the approach in babies is controversial. A surveillance strategy is propagated by some groups. In this retrospective study, we evaluated age and stage at diagnosis, therapy and outcome of patients treated at our institutions since 1970. Material and methods 90 patients with retroperitoneal neuroblastomas were treated. They were divided into 2 groups according to age at time of diagnosis:  1 year. Results 40 patients were  1 year (1- 18 years). Detection of an asymptomatic tumour:  1 year 10%. Tumor stage at diagnosis > 1 y…

2018

Objective There is a very limited amount of research on the relationship between therapist and patient in-session behavior and treatment outcome in cognitive behavioral therapy (CBT) for panic disorder with agoraphobia (PD/AG). Additionally, the findings tend to be inconclusive. This study investigates the association between therapist competence, adherence, patient interpersonal behavior, and therapeutic alliance and outcome in a low-control CBT setting by using comprehensive measures. Methods Twenty-six patients with PD/AG received 12 sessions of exposure-based CBT. With regard to the outcome, treatments were classified either as problematic or nonproblematic by means of distinct criteria…

The effect of urine volume and nitric oxide on basal bladder blood flow: Response to catheterization and drainage

2000

Preliminary studies demonstrated that catheterization and drainage of the urinary bladder resulted in a significant increase in blood flow to the bladder. The objectives of this study were to determine 1) the relationship between urine volume and basal blood flow to the bladder smooth muscle and mucosa, 2) the effect of acute catheterization and drainage on bladder mucosal and smooth muscle blood flow, and 3) whether nitric oxide was involved in regulation of basal blood flow or the increase in blood flow observed after catheterization and bladder drainage. Twenty-four rabbits were separated into two groups: group 1 (14 rabbits) and group 2 (10 rabbits) treated with L-NAME (NOS inhibitor) 3…

SARS-CoV-2 outbreak in medical employees in a large urologic department: Spread, containment and outcome.

2021

Background The SARS-CoV-2 pandemic presents an unprecedented challenge to health care systems worldwide. Data on SARS-CoV-2 transmission in a hospital is rare and outbreaks among health care professionals are complex to control. Material and Methods Over the course of 6 consecutive weeks we recorded data on an exponential outbreak of SARS-CoV-2 within our department. We reconstructed the assumed route of the spread of infection, and the employees’ acute and late symptoms. Increasing preventive measures (mandatory face masks, intense training in hygiene, physical distancing whenever possible, and termination of visits from outside the hospital) were implemented. Results Within 6 weeks, 13 em…

Phenotype severity in the bladder exstrophy-epispadias complex: analysis of genetic and nongenetic contributing factors in 441 families from North Am…

2011

Objective To identify genetic and nongenetic risk factors that contribute to the severity of the bladder exstrophy-epispadias complex (BEEC). Study design Patients with BEEC from North America (n = 167) and Europe (n = 274) were included. The following data were collected: associated anomalies, parental age at conception, mode of conception, periconceptional folic acid supplementation, maternal risk factors during pregnancy, and environmental risk factors. The patients were divided into 3 subgroups according to phenotype severity: (i) mild, epispadias (n = 43); (ii) intermediate, classic bladder exstrophy (n = 366); and (iii) severe, cloacal exstrophy (n = 31). These subgroups then were com…

Ist die Hormontherapie bei Hodenhochstand noch zeitgemäß?

2020

ZusammenfassungDie Hormontherapie wurde über Jahrzehnte (zumindest in Europa) als integraler Bestandteil der Behandlung des Hodenhochstandes angesehen. Die Datenlage ist jedoch ausgesprochen kontrovers. Die Induktion des Deszensus gelang in vielen Studien und laut einer großen Metaanalyse nur in ca. 20 % der Fälle, einzelne kleinere Studien beschreiben bessere Ergebnisse. Auch die potenzielle Verbesserung der Fertilität wird in einigen Studien als erwiesen angegeben, andere beschreiben gegenteilige Ergebnisse.Inzwischen wurde die Hormontherapie aus den meisten internationalen Leitlinien vollends entfernt und wird auch in Deutschland nur noch für wenige Indikationen empfohlen. Bez. der Induk…

Network Analysis of Persistent Somatic Symptoms in Two Clinical Patient Samples

2021

OBJECTIVE Previous attempts to group persistent somatic symptoms (PSS) with factor-analytic approaches have obtained heterogeneous results. An alternative approach that seems to be more suitable is the network theory. Compared to factor analysis, which focuses on the underlying factor of symptoms, network analysis focuses on the dynamic relationships and interactions among different symptoms. The main aim of this study is to apply the network approach to examine the heterogeneous structure of PSS within two clinical samples. METHODS The first dataset consisted of N = 254 outpatients who were part of a multicentre study. The second dataset included N = 574 inpatients, both with somatoform di…

Radical surgery and different types of urinary diversion in patients with rhabdomyosarcoma of bladder or prostate--a single institution experience.

2013

Abstract Purpose In a retrospective study we analyzed the outcome of patients treated for rhabdomyosarcoma (RMS) of the bladder/prostate with special attention to radical surgery. Methods In 25 patients with genitourinary RMS (15 bladder/10 prostate) the median age at diagnosis was 4 years [1] , [2] , [3] , [4] , [5] , [6] , [7] , [8] , [9] , [10] , [11] , [12] , [13] , [14] , [15] , [16] , [17] , [18] , and 8 patients had a stage II RMS, 12 stage III and 5 stage IV. In 19/25 (12 bladder/7 prostate), radical surgery and urinary diversion were performed. Urinary diversion comprised 2 continent anal diversions, 11 continent cutaneous diversions, 4 colon conduits and 2 urethral diversions (2 +…

New strategies for medical management of overactive bladder in children.

2011

Purpose of review The medical treatment of children with non-neurogenic overactive bladder syndrome (OAB) is still limited to a small number of drugs approved for use in childhood according to the national regulations of each country. Recent findings Over the last few years, there were several studies on the use of antimuscarinics other than oxybutynin in children, as well as some on the use of extended release oxybutynin and tolterodine and transdermal oxybutynin. It was shown that the combination of two different anticholinergics might be a well tolerated and successful option in children with OAB refractory to monotherapy, as well as administration of a receptor-selective antimuscarinic …

Der Maldeszensus testis ist die haufigste genitale Fehlbildung des Mannes. Unbehandelt kann er nicht nur die Fertilitat beeintrachtigen, sondern erhoht auch das Risiko fur die Entstehung eines Hodentumors. Um diese Gefahren zu minimieren, sollte die Therapie moglichst bis zum 12. Lebensmonat abgeschlossen sein.

Ossifying renal tumor of infancy

2007

A renal ossifying tumor of infancy is a rare event with few cases having been published, and the etiology has not yet been established. We report on two new cases of this unusual neoplasm. A 2-year-old boy presented with intermittent painless gross hematuria. After several diagnostic procedures, an open pyelolithotomy was performed and the histological diagnosis of renal tumor of infancy was finally made. The history of the second case is very similar. An 8-week-old infant presented with gross hematuria. As in the first case, an open pyelolithotomy was performed and a tumor entirely covered with blood clots was found in the renal pelvis and completely removed. A histological diagnosis of re…

Effects of a vitamin D3 analogue in a rat model of bladder outlet obstruction

2006

OBJECTIVES To explore the effect of the vitamin D3 analogue, BXL-628, on some of the consequences of bladder outlet obstruction (BOO), e.g. hypertrophy and loss of contractile function, as vitamin D3 and BXL-628 inhibit prostate and bladder cell growth in vitro, and there are receptors for vitamin D in rat and human bladder. MATERIAL AND METHODS In female rats, BOO was produced by a standardized method; one group received daily BXL-628 (150 µg/kg per day) and the remaining rats received vehicle. Sham-operated rats received BXL-628 or vehicle. After 2 weeks, the conscious rats were assessed by cystometry. Plasma calcium levels were determined and in vitro contractility assessed at the end of…

Increased blood flow after catheterization and drainage in the chronically obstructed rabbit urinary bladder

2001

Abstract Objectives. To determine the effect of drainage on rabbit bladder blood flow after 4 weeks of partial outlet obstruction. Previous studies have shown that catheterization and drainage of the urinary bladder in control rabbits resulted in a significant nitric oxide-induced increase of blood flow to the bladder. It was also shown that 4 weeks’ partial outlet obstruction caused a significant decrease in blood flow to the bladder. Methods. Male New Zealand White rabbits underwent partial outlet obstruction by standard methods. After 4 weeks, the blood flow to the bladder muscle and mucosa was determined by a microsphere technique. Within 1 to 2 minutes after transurethral catheterizati…
