Long-term followup of the intussuscepted ileal nipple and the in situ, submucosally embedded appendix as continence mechanisms of continent urinary d…
2006
We analyzed stoma related complications and continence rates in patients who underwent continent urinary diversion with the cutaneous ileocecal pouch (Mainz pouch I). We compared the intussuscepted ileal nipple and in situ, submucosally embedded appendix as continence mechanisms.A total of 401 patients were included in a retrospective followup study. Continence mechanisms were the intussuscepted ileal nipple in 205 patients and the in situ, submucosally embedded appendix in 196.A total of 144 patients (36%) required intervention for a stomal complication. Of patients who received an intussuscepted ileal nipple 34 (17%) had stomal stenosis at a mean time to first stenosis of 43.8 months, 41 …
Conversion from colonic conduit into recto-sigmoid pouch (Mainz pouch II)
2005
The Mainz Pouch II has now been used widely and found to be a valuable addition to the various types of urinary diversion. The authors from Mainz describe how a colonic conduit can be converted into a Mainz Pouch II, and the expected outcome from such a procedure. OBJECTIVE To report our long-term results of conversion from conduit conversion into a continent anal urinary diversion, as after conduit urinary diversion in childhood, some patients wish to have a later conversion to a continent diversion to avoid external appliances and to improve their quality of life. PATIENTS AND METHODS Between 1992 and 2003, 139 patients had a urinary diversion with a recto-sigmoid pouch (Mainz pouch II), …
Ileocecal valve reconstruction during continent urinary diversion.
1994
During construction of an ileocecal reservoir, such as the Mainz or Indiana pouch, the ileocecal valve is lost. Subsequently, the intestinal transit time is shortened and malabsorption as well as diarrhea may result. Patients having undergone previous bowel resection as well as children with myelomeningocele who often already have frequent defecations will be heavily affected by the loss of the ileocecal valve. We have functionally reconstructed the ileocecal valve by embedding ileum into the ascending colon via a submucosal tunnel in analogy to the technique used when creating the continence mechanism during the Mainz pouch procedure using the appendix. Experimental results in 15 dogs demo…
The Mainz Pouch (Mixed Augmentation Ileum and Cecum) for Bladder Augmentation and Continent Diversion
1986
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 …
URINARY DIVERSION AND ORTHOTOPIC BLADDER SUBSTITUTION IN CHILDREN AND YOUNG ADULTS WITH NEUROGENIC BLADDER: A SAFE OPTION FOR TREATMENT?
2000
Combined pharmacotherapy, clean intermittent catheterization and infection prophylaxis is currently the gold standard of treatment for neurogenic bladder. However, as the adolescent gains independence from parental supervision, the intervals of clean intermittent catheterization compliance with medical treatment and regularity of followup examinations may decrease, and neurological and/or orthopedic status may change. This situation sometimes leads to failure of conservative treatment, resulting in incontinence and/or deterioration of the upper urinary tract. A multidisciplinary team was established at our institution 30 years ago to assess all aspects of care for patients with neurogenic b…
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 +…
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…
Treatment of relapsing-remitting multiple sclerosis after 24 doses of natalizumab: evidence from an Italian spontaneous, prospective, and observation…
2014
Importance The evaluation of therapeutic choices is needed after 24 doses of natalizumab in patients with multiple sclerosis (MS). Objective To evaluate the effect of therapeutic choices on the mean annualized relapse rate and on magnetic resonance imaging MS activity after 24 doses of natalizumab in patients with relapsing-remitting MS. Design, Setting, and Participants The TY-STOP study, which recruited participants between October 22, 2010, and October 22, 2012, at 8 Italian MS centers (secondary care outpatient clinics) among 124 adult patients who demonstrated no clinical or magnetic resonance imaging MS activity after 24 doses of natalizumab. Interventions Natalizumab, no treatment, i…
Stroop task performance across the lifespan: High cognitive reserve in older age is associated with enhanced proactive and reactive interference cont…
2020
Abstract Susceptibility to interference increases with age but there is large inter-individual variability in interference control in older adults due to a number of biological and environmental factors. The present study aims at analyzing behavior and ERPs in a Stroop interference task with increasing difficulty in a sample of 246 young, middle-aged and healthy old participants. The old age group was divided into three subgroups based on performance scores. The results show a gradual performance reduction with increasing age and task difficulty. However, old high performers reached a performance level comparable to middle-aged subjects. The contingent negative variation (CNV) reflecting pr…
Anal endosonographic evaluation after closed lateral subcutaneous sphincterotomy
1998
PURPOSE: The present study was undertaken to evaluate anal endosonographic results of the transverse and longitudinal extent of internal anal sphincter division after closed lateral subcutaneous sphincterotomy and its relationship to outcome with respect to anal fissure recurrence and postoperative anal incontinence. METHODS: Ten patients selected for symptomatic anal fissure recurrence (mean follow-up, 10.9 months) and 41 asymptomatic control patients (mean follow-up, 15.5 months) were reviewed by anal endosonography after closed lateral subcutaneous sphincterotomy. Clinical evaluation was focused on anal fissure recurrence and postoperative anal incontinence. The anal endosonographic stud…
