Colon pouch (Mainz III) for continent urinary diversion.

Objective: To evaluate the use of a continent cutaneous pouch made exclusively of colon (Mainz pouch III), as excellent results with the Mainz pouch III in irradiated patients suggested that the indication for this type of urinary diversion could be extended.

Patients And Methods: The outcome of 24 patients with continent cutaneous urinary diversions using colon segments (Mainz pouch III) was investigated retrospectively. Overall, 22 of the patients had a malignant disease and two a benign disease; 16 had a hysterectomy and pelvic exenteration for gynaecological tumours; two men with a rhabdomyosarcoma of the prostate had a radical cystoprostatectomy; one woman had pelvic exenteration for bladder cancer; one man had a simultaneous rectum resection due to infiltrating rectal cancer, and another a left nephrectomy with cystectomy for concomitant kidney and bladder tumour.

Uretero-ureterocutaneostomy (wrapped by omentum).

Unlabelled: The tubularized-incised plate urethroplasty has traditionally been used in children for repairing hypospadias. As shown here, it can also be used successfully in adults, with very good results. The rate of wound healing, infection and complications is the same as in children, as are the cosmetic and functional outcomes.
