[Ureterosigmoidostomy with the formation of low pressure reservoir: history or operation of choice? 15 years of experience].

Aim: To examine the long-term outcomes of Mainz Pouch II ureterosigmoidostomy with the formation of a submucosal and extramural by Hassan (Hassan Abol-Enein) tunnels.

Materials And Methods: Mainz Pouch II ureterosigmoidostomies with the formation a submucosal tunnel (open-end technique) comprised group 1 (n=17) and with the formation of extramural ureteral implantation by Hassan - group 2 (n=15). The mean age of patients was 58+/-6.

[Overcontinence in females after orthotopic replacement of the urinary bladder].

Treatment results were analysed for 27 patients (mean age 53 +/- 7 years) after orthotopic urinary diversion (by the method of Studer, Hautmann) following radical cystectomy. Radical cystectomy was performed without nerve preservation in all the patients. Overcontinence was detected in 4 (26.

[Determination of optimal length of extramural tunnels for their adequate anticurrent properties in intestinal urine derivation].

An acute experiment on adult dogs with conduction of manometry in outlets and inlets in reservoir filling and with Valsalva's test has established that reliable continent properties of the anti-current mechanisms are provided in creation of the tunnel with functional length 5 cm minimum leading to proportional rise in pressure in reservoir and in outlet. Pressure in the outlet was approximately 2 times higher than in the reservoir. In tunnel length 4 cm Valsalva's test registered leaking.

[A comparative analysis of antireflux and direct methods of ureteral implantation in intestinal continent urinary derivation].

Intestinal continent urinary derivation was made from 1997 to 2006 in three groups of patients. The following kinds of derivation were performed: ureterosygmostomy according to Maintz-Pouch and Abol-Enein modification (group 1, n=32); heterotopic replacement of the urinary bladder in various modifications (group 2, 50 patients); orthotopic replacement according to Hautmann, Studer, Abol-Enein, sygmocystoplasty, n=51). In group 1 ureterosygmoanastomosis was created only by antireflux methods: Goodwin and Hohenfellner submucous technique and Abol-Enein extramural implantation.
