Urinary diversion in children and young adults using the Mainz Pouch I technique

Abstract

Objectives To determine the late complications and remaining patients). Two of 32 patients with an intussuscepted and invaginated ileal nipple required consequences for renal function, vitamin and acidbase metabolism after application of the Mainz Pouch re-operation due to incontinence, but none of the patients with an appendiceal stoma were incontinent. I (MZP-I) technique in children and young adults. Patients and methods To November 1994, the MZP-I Open revision of a stomal stenosis was performed in three and endoscopic treatment in nine patients. In procedure was carried out in 463 patients at our institution, 91 of whom were children and adolescents 54 patients, the levels of vitamins A, B 1 , B 2 , B 6 , E, folic and bile acid were within normal ranges. There (∏20 years old) using bladder augmentation in 21 and a continent cutaneous stoma in 70. A minimum was no significant decrease in vitamin B 12 levels after operation. In none of the patients with normal follow-up of 1 year was possible in 87 patients or 163 renal units (RUs) with a mean of 5.5 years (range pre-operative creatinine values had the levels increased and none developed severe acidosis or bowel 1-10.5).Results At the last examination, 23 of 55 (42%) preneoplasm. Conclusion The MZP-I is recommended as a technique operatively dilated RUs had improved, 131 of the 163 RUs (80%) were stable and nine RUs (5.5%) showed for bladder augmentation or continent urinary diversion in children and young adults, with an acceptable a slight clinical asymptomatic increase in the upper tract dilatation. Through an extraperitoneal flank complication rate which offers long-term protection of the upper urinary tract. incision, 11% of the RUs which developed stenosis at the ureterocolic anastomosis were successfully reimKeywords Continent urinary diversion, children, upper urinary tract, complications, metabolic planted (16% in patients with neurogenic disorders, 17% with pre-operative irradiation and 5% in the The MZP-I procedure was introduced in 1983 [2] and

Ileal Enterocystoplasty and B12 Deficiency in Pediatric Patients

“…Stein et al reviewed their experience with the Mainz pouch I in 463 patients, of whom 91 were 20 years or younger. 6 They found no significant decrease in vitamin B12 postoperatively. Mean followup in that study was 5.5 years, while in our study it was 7.3 years.…”

Urinary diversion in children and adolescents with neurogenic bladder: the Mainz experience

“…BE <2.5 mmol/l). A decrease in vitamin B 12 levels, which was demonstrated in other series following ileal resection [36,37], was not observed in children with an ileocaecal reservoir [38,39].…”

Urinary diversion in childhood: indications for different techniques

“…a slight effect on the blood supply, a lower risk of leakage and a more direct route for catheterization. Our results with the appendiceal stoma in children [ 31] are described later.…”

“…Only techniques in widespread use are considered; the creation of a spherical reservoir is currently the standard procedure. In our patients, the ileocaecal segment is used to form the pouch in adults [ 35–37] and in children [ 31, 38]. For augmentation and urinary diversion, the technique at our institution using the ileocaecal segment is explained below as an example.…”

“…Colonic and ileal segments are most often used for bladder augmentation or urinary diversion with a continent stoma [ 26–31]. The colon has various advantages over the ileum, i.e.…”
