Abstract

Objectives : To evaluate the functional outcome of the Charleston pouch procedure as a continent catheterizable urinary reservoir using an unaltered in-situ appendix with a triangular skin flap at its umbilical stoma with few modifications to the original technique.Patients and Methods: Between February 1999 and October 2002, 34 patients (31 males and 3 females) were studied at the Urology Department, Assiut University Hospital, Assiut, Egypt. The indications for urinary diversion were radical cystectomy for invasive carcinoma of the bilharzial bladder in 27 males and three females, and incontinent epispadias in four male patients. The age of the patients ranged between 18 and 60 years (mean 48.1± 6.1 years). Mean follow up was 30 ± 4.2 months (range 11-40 months). The evaluation during the follow-up period included clinical, laboratory, imaging and urodynamic studies to evaluate the functional outcome.Results: All patients are continent (day and night). No stomal stenosis was recorded. Laboratory investigations were within normal. The upper urinary tract remained unchanged in all patients.Pouchometry revealed that the Charleston pouch is a low-pressure (4 –21 cm H2O) reservoir with a good capacity (average750 ml). Cancer recurrence was recorded in 3 patients at 12, 27 and 32 months. Conclusions: The Charleston pouch with in-situ appendix is an efficient versatile technique for the creation of a catheterizable continent cutaneous urinary reservoir. The umbilical stoma with triangular skin flap provides excellent cosmetic results. Le Reservoir de Charleston avec Appendice In Situ et Stomie Ombilicale Cachee Objectifs: Evaluer le resultat fonctionnel du reservoir de Charleston comme derivation urinaire continente catheterisable via un appendice insitu avec une plicature cutanee triangulaire au niveau de sa stomie ombilicale avec quelques modifications de la technique originale. Patients et Methodes: Trente-quatre patients (31 mâles et 3 femmes) ont ete eliges entre fevrier 1999 et octobre 2002 au Departement d'Urologie, a l'Hopital Universitaire d'Assiut, Assiut, Egypte. Les indications pour derivation urinaire etaient des cystectomies radicales pour carcinome invasif bilharzien de la vessie chez 27 hommes et trois femmes, et epispadias incontinent chez quatre hommes. L'âge des patients etait entre 18 et 60 ans (moyenne 48.1 ± 6.1 annees). La moyenne du suivi etait 30 ± 4.2 mois (11-40 mois). Le suivi etait clinique, biologique, bacteriologique, radiologique et urodynamique pour evaluer le resultat fonctionnel. Resultats: Tous les patients sont continents (jour et nuit). Aucune stenose stomiale n'a ete notee. Les examens biologiques etaient normaux. Le haut appareil urinaire est reste inchange chez tous les patients. L'etude des pressions du reservoir a revele qu'elle est de basse pression (4 –21 centimetre H2O) reservoir avec une bonne capacite (moyenne 750 ml). La recidive du cancer a ete notee chez 3 patients a 12, 27 et 32 mois. Conclusions: Le reservoir de Charleston avec appendice in situ est une technique flexible effective pour creer un reservoir urinaire continent catheterisable cutane. La stomie ombilicale avec flap cutane triangulaire fournit des resultats esthetiques excellents. African Journal of Urology Vol.9(4) 2003: 176-181
