Long-term follow-up of submucosal tunnel and serosa-lined extramural tunnel ureter implantation in ileocaecal continent cutaneous urinary diversion (…

2007

Authors from Mainz, Germany present the long-term follow-up of submucosal tunnel and serosa-lined extramural tunnel ureter implantation in the ileocaecal continent cutaneous urinary diversion first described in that department, called the Mainz-Pouch I. OBJECTIVE To assess upper urinary tract complications and renal function in patients with a submucosal tunnel and serosa-lined extramural tunnel ureter implantation during the long-term follow-up of ileocaecal continent cutaneous urinary diversion (Mainz pouch I). PATIENTS AND METHODS In all, 458 patients who had diversion with the ileocaecal pouch were analysed in a retrospective follow-up study. Uretero-intestinal implantation was done usi…

Elective segmental ureterectomy for transitional cell carcinoma of the ureter: Long-term follow-up in a series of 73 patients

2012

What's known on the subject? and What does the study add? Upper Urinary Tract (UUT) Transitional Cell Carcinoma (TCC) is an uncommon disease and represents approximately 5% of all urothelial carcinomas. We report our series on 73 patients treated with Kidney Sparing Surgery for UUT TCC. Good results have been achieved in terms of oncological outcome comparing this conservative approach to the radical nephrourectomy. OBJECTIVES: • To report the long-term oncological outcome in patients with transitional cell carcinoma of the ureter electively treated with kidney-sparing surgery. • To compare our data with the few series reported in the literature. PATIENTS AND METHODS: • We considered 73 pat…

Retrograde endoureterotomy as a treatment option for impacted calculus in the ureterointestinal junction

2021

Introduction: In patients with a history of radical cystectomy and with intestinal diversion, urolithiasis in the upper urinary tract is a frequent event. Material and methods: We describe for the first time a case of retrograde endoureterotomy used to treat a calculus proximal to the ureterointestinal junction. Results: This technique is of interest when antegrade access is not possible. In our example, after passing the guidewire percutaneously, and externalize it through the stoma, the left meatus was reached with a resectoscope inserted through the ileal duct. After the use of a balloon to prevent migration of the calculus, a retrograde endoureterotomy was performed with a Collins knife…

Colonic Conduit in Children

1996

Complication rates of up to 86.6% have been reported after creation of an ileal conduit. In contrast to others, we construct an antirefluxing isoperistaltic colonic for incontinent diversion in children.Between 1968 and 1989 a colonic conduit was created in 105 patients up to age 20 years for neurogenic bladder (76), bladder exstrophy (16) and other reasons (13). Long-term followup (minimum 5 years, mean 16.3 years, range 5 to 26) was possible in 84 patients (159 renal units).Early and late stenosis at the ureterocolic anastomosis, and stomal stenosis occurred in 7.6 and 15.5% of the cases, respectively. Renal calculi developed in 8.2% of the renal units. Eight kidneys without function afte…

Urinary tract infections in children: EAU/ESPU guidelines.

2015

Context: In 30% of children with urinary tract anomalies, urinary tract infection (UTI) can be the first sign. Failure to identify patients at risk can result in damage to the upper urinary tract.Objective: To provide recommendations for the diagnosis, treatment, and imaging of children presenting with UTI.Evidence acquisition: The recommendations were developed after a review of the literature and a search of PubMed and Embase. A consensus decision was adopted when evidence was low.Evidence synthesis: UTIs are classified according to site, episode, symptoms, and complicating factors. For acute treatment, site and severity are the most important. Urine sampling by suprapubic aspiration or c…

Treatment strategies and outcome of the exstrophy–epispadias complex in germany: data from the german CURE-Net

2020

Introduction: To evaluate the impact of reconstructive strategies and post-operative management on short- and long-term surgical outcome and complications of classical bladder exstrophy (CBE) patients' comprehensive data of the multicenter German-wide Network for Congenital Uro-Rectal malformations (CURE-Net) were analyzed. Methods: Descriptive analyses were performed between 34 prospectively collected CBE patients born since 2009, median 3 months old [interquartile range (IQR), 2–4 months], and 113 cross-sectional patients, median 12 years old (IQR, 6–21 years). Results: The majority of included individuals were males (67%). Sixty-eight percent of the prospectively observed and 53% of the …

Treatment with phenoxybenzamine of upper urinary tract complications caused by intravesical obstruction.

1975

Five children in whom reflux and progressive hydronephrosis persisted despite multiple surgical attempts or repair are described. In all cases cystomanometry displayed a marked elevation of the bladder outlet resistance combined with high intravesical pressure values. Therapy with phenoxybenzamine, an alpha-adrenergic blocker, was successful in all cases, restoring a free urine passage of the upper urinary tract and unimpaired voiding preventing urinary diversion which has been considered in some of these children. Although there were no signs of bladder neuropathy, a hyperfunction of the sympathetic innervation as acause for bladder complications is discussed.

The Mainz pouch II (sigma rectum pouch).

1993

A low pressure rectosigmoid reservoir for urine is created obviating the need for colostomy, augmentation or extensive bowel surgery. Antimesenteric splitting of the intestine at the rectosigmoid junction and subsequent side-to-side anastomosis are performed. Urodynamic data demonstrate that the detubularization is effective in rendering high pressure bowel contractions ineffective. Without the risk of damaging the mesentery the pouch is fixed at the promontory, which lessens the risk of ureteral kinking and upper urinary tract dilatation. The technique is indicated not only in cases of failed ureterosigmoidostomy but also for primary urinary diversion. All 47 patients who underwent the ope…

Keratinizing Desquamative Squamous Metaplasia of the Upper Urinary Tract: Leukoplakia—Cholesteatoma

Kinder und Jugendliche mit neurogener Blasenfunktionsst�rung

2004

After the failure of conservative treatment in patients with neurogenic bladders, urinary diversion is a viable compromise between the urologist's concerns and the patient's desire, as the upper urinary tract can be protected in the long-term and high continence rates can be provided. This can be achieved with an acceptable complication rate. Our indications for orthotopic bladder augmentation or substitution involve patients with a good orthopedic condition and mobility, who find it easy to perform CISC through the urethra. A continent umbilical stoma offers a good alternative in obese, immobile or wheelchair bound patients. The serous lined extramural tunnel technique has proven to be sup…
