Vascular Health Assessment of The Hypertensive Patients (VASOTENS) Registry: Study Protocol of an International, Web-Based Telemonitoring Registry fo…

2016

Background: Hypertension guidelines recommend ambulatory blood pressure (ABP), central aortic pressure (CAP), and pulse wave velocity (PWV) as parameters for estimating blood pressure (BP) control and vascular impairment. Recent advances in technology have enabled devices to combine non-invasive estimation of these parameters over the 24-hour ABP monitoring. However, currently there is limited evidence on the usefulness of such an approach for routine hypertension management. Objective: We recently launched an investigator-initiated, international, multicenter, observational, prospective study, the Vascular health Assessment Of The Hypertensive patients (VASOTENS) Registry, aimed at (1) eva…

Bladder augmentation using bowel segments (enterocystoplasty)

Long-term outcome after urinary diversion using the ileocecal segment in children and adolescents: Complications of the efferent segment.

2016

Long-term outcomes are of special concern in children after urinary diversion. In a single institution study we evaluated retrospectively the long-term outcomes of urinary diversion in children, in whom the ileocecal segment had been used, in respect to complications of the efferent segment.The Mainz pouch was used in 107 children for continent urinary diversion. Indications were neurogenic bladder (53%, 57/107), exstrophy-epispadias complex (25%, 27/107), malignancy (13%, 14/107), and others (9%, 9/107). Continent cutaneous diversion was performed in 95 patients, and 12 patients received bladder augmentation/substitution with a continent cutaneous stoma. As efferent segment, we used the in…

The mainz-pouch (mixed augmentation ileum 'n zecum) for bladder augmentation and continent diversion

1985

The ideal urinary reservoir constructed from bowel material should be a low-pressure system with a high capacity, capable of preventing upper tract deterioration resulting from ureteral obstruction or reflux. It should achieve reliable control of continence and assure easy emptying of the reservoir. In the Mainz-pouch, the combination of cecum and ileum, the latter of which is able to absorb pressure waves created by the cecum, produces a low-pressure system with a high capacity immediately postoperatively. By incorporating large bowel in our pouch, ureteral implantation can be done using a simple and reliable standard antireflux technique with a submucosal tunnel. The Mainz-pouch has been …

Continent diversion with the Mainz pouch.

1996

From 1983 until July 1994, 561 patients in 2 urology departments (Mainz and Wuppertal) underwent a Mainz pouch 1 procedure. The Mainz pouch 1 was used for bladder augmentation in 60 patients, for orthotopic bladder substitution in 61 patients, and for continent cutaneous urinary diversion in 440 patients. In the group of continent cutaneous urinary diversion, the continence mechanism applied was an ileal intussusception nipple in 270 patients, an appendix stoma in 146 patients, a submucosal seromuscular bowel-flap tube in 14 patients, and a submucosal full-thickness bowel-flap tube in 10 patients. Indications for urinary diversion were bladder cancer in 339 patients, anatomical or functiona…

Activation of Astrocytes in the Persistence of Post-hypoxic Respiratory Augmentation

2021

Acute hypoxia increases ventilation. After cessation of hypoxia loading, ventilation decreases but remains above the pre-exposure baseline level for a time. However, the mechanism of this post-hypoxic persistent respiratory augmentation (PHRA), which is a short-term potentiation of breathing, has not been elucidated. We aimed to test the hypothesis that astrocytes are involved in PHRA. To this end, we investigated hypoxic ventilatory responses by whole-body plethysmography in unanesthetized adult mice. The animals breathed room air, hypoxic gas mixture (7% O2, 93% N2) for 2min, and again room air for 10min before and after i.p. administration of low (100mg/kg) and high (300mg/kg) doses of a…

Orthotopic bladder augmentation and substitution.

1999

Orthotopic bladder augmentation or substitution using intestinal segments has become a standard procedure for many disorders that cause a loss of functional or anatomical bladder capacity. From the technical point of view, reservoir configuration by detubularizing the intestinal segments is the general practice. Various techniques exist, depending which types of segments and which techniques of ureteral implantation are used. Common problems include urinary incontinence, retention, metabolic disorders, and the possibility of secondary malignancies. As a result, research has been conducted into utilizing tissues other than intestine for bladder augmentation or substitution.

Urinary diversion and reconstruction.

2000

Orthotopic bladder augmentation and substitution has been established as the standard procedure for urinary diversion in many institutions, with current studies reporting mainly on continence rates and procedure-associated complications, such as the risk of impairment of neobladder function by local tumor recurrences in the small pelvis. Similarly, in other types of continent diversion, such as continent cutaneous diversion and rectal reservoirs, current interest is primarily directed towards minimization of surgery-associated complications.

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…

Applications of Ureterosigmoidostomy in Bladder Exstrophy

1999

Until 1994, 95 patients with bladder exstrophy and 20 with incontinent epispadias were operated upon at our department. During the last years more and more exstrophycripples were referred to our institution after primary treatment elsewhere. Thus a total of 56 of the 104 patients had a secondary treatment after failure or unsatisfactory treatment. In contrast to many other institutions, our standard procedure was primary ureterosigmoidostomy and, since 1990 it is completely replaced by a modification of it, the sigma rectum pouch (Mainz Pouch II). After failed primary bladder closure and in patients with short or pathological ureters or insufficient anal sphincter function, we prefer an ile…
