[Continent derivation of urine (a Modo) Mainz II].

The improved intestinal dissection technique and antibiotic agents, and the development of new resorptive suture materials have led to renewed surge of interest in ureterosigmoidostomy as a practicable procedure for continent derivation. Based on data from urodynamic assessment of diverse forms of urinary derivation, M Fisch and R Hohenfellner in 1991 propose a modification of the classical technique of ureterosigmoidostomy, coined with the term Sigmarectum pouch or Mainz pouch (M Fisch, R. Wammack, R Hohenfellner 1991). Over the period 1992 through 1999, 46 operations type "Mainz II" are performed in the Department of Urology--University Hospital "Alexandrovska". The series includes 41 men and 5 women with age range 42 to 80 years. All patients present urinary bladder tumors. The usual surgical technique is used. The severest postoperative complications include: urinary fistulae--3 (6.52%), local relapse--4 (8.69%) and distant metastases--2 (4.35%). In six patients the outcome is fatal (0.7%). This type of continent derivation following cystectomy is recommended since it is convenient, practically atraumatic and well tolerated by the patients. Complications encountered seldom necessitate operative intervention.
