Continent urinary diversion in childhood

1992

Continence and a positive body image are important, especially to the adolescent patient. Since 1964 we have used ureterosigmoidostomy and have achieved a complete continence rate of 92.3%. The creation of a low-pressure reservoir by antimesenteric splitting of the recto-sigmoid eliminated many of the shortcomings of ureterosigmoidostomy. This procedure is termed the sigma-rectum pouch and has been applied in six children to date. Mainz-pouch bladder augmentation or substitution has been performed in 20 children, 17 of whom are completely continent. The results of the modified Young Dees procedure were disappointing. In three children, conversion into a continent diversion was necessary. Al…

Kontinente Harnableitung und Schwangerschaft

1995

We report on our experience with 7 pregnancies in 6 women who previously underwent reconstruction of the urinary tract with a continent urinary diversion using an ileo caecal segment (Mainz-Pouch I), ureterosigmoidostomy or bladder augmentation. Urinary tract infection and upper tract dilatation were the only complications during pregnancy which required bilateral nephrostomies in one case. All other sequelae were handled conservatively. The continence mechanisms were not compromised during pregnancy or delivery. Deliveries were vaginal in two cases and by Caesarean section in five. All seven newborn were healthy. Pregnancy is not contraindicated after any type of urinary diversion includin…

"Doctor, tengo un bulto en la axila". Adenomegalia siliconomatosa postmamoplastia de aumento: a propósito de ocho casos

2010

La aparición de adenopatías axilares asociadas a mamoplastia de aumento mediante prótesis de silicona es un hecho infrecuente, no excepcional, y muy preocupante para paciente y cirujano. Hemos hecho una revisión de 1697 historias clínicas de pacientes sometidas a mamoplastia de aumento mediante prótesis de silicona al objeto de estudiar la relación entre roturas protésicas y adenopatías axilares Las 1697 pacientes se dividieron en grupos que cumplían 1, 2, 3, 5 y 7 años de haber sido intervenidas. Revisamos sus historias clínicas y estudiamos las que con posterioridad a la cirugía habían consultado por sospecha de rotura protésica y adenopatías axilares. No encontramos roturas protésicas an…

Nanocrystalline Hydroxyapatite Bone Substitute Leads to Sufficient Bone Tissue Formation Already after 3 Months: Histological and Histomorphometrical…

2012

Purpose: In this study the de novo bone formation capacity of a nanocrystalline hydroxyapatite bone substitute was assessed 3 and 6 months after its insertion into the human sinus cavity. Materials and Methods: Sinus cavity augmentation was performed in a total of 14 patients (n = 7 implantation after 3 months; n = 7 implantation after 6 months) with severely atrophic maxillary bone. The specimens obtained after 3 and 6 months were analyzed histologically and histomorphometrically with special focus on bone metabolism within the residual bone and the augmented region. Results: This study revealed that bone tissue formation started from the bone-biomaterial-interface and was directed into th…

A prospective, randomized pilot study on the safety and efficacy of recombinant human growth and differentiation factor-5 coated onto β-tricalcium ph…

2010

Objectives: The aim of this prospective, randomized clinical trial was to investigate the potential of recombinant human growth and differentiation factor-5 (rhGDF-5) coated onto β-tricalcium phosphate (β-TCP) (rhGDF-5/β-TCP) to support bone formation after sinus lift augmentation. Material and methods: In total, 31 patients participated in this multicenter clinical trial. They required a two-stage unilateral maxillary sinus floor augmentation (residual bone height <5 mm). According to a parallel-group design, the patients were randomized to three treatment groups: (a) augmentation with rhGDF-5/β-TCP and a 3-month healing period, (b) augmentation with rhGDF-5/β-TCP and a 4-month healing per…

Meta-analytic study of implant survival following sinus augmentation

2011

Objectives: To evaluate graft types used for maxillary sinus augmentation and review success rates of dental implants inserted in these areas, analyzing the graft materials used, implant surface types and the moment of implant placement. Study Design: A meta-analytic study reviewing articles on sinus augmentation published during the last ten years. Results: 3,975 implants placed in sinus augmentations (with bony windows) were registered, of which 3,749 implants survived, a survival rate of 94.3%. Conclusions: When performing sinus augmentation, bone substitute materials are just as effective as autologous bone, whether used alone or in combination with autologous bone. Implant surface trea…

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 …
