Operational technique for the rectum tumors, localized at the level of dentate line, developed in the State center of coloproctology, allows preservation of external anal sphincter elements and thus, partial preservation of defecation control. Technique is described and proved, preliminary treatment results of 42 patients are analysed. The operation is oncologically effective (local recurrence rate 4,8%). Preservation of external sphincter elements has a high functional value in complex with "neorectum" and "neosphincter". A majority of operated patients can keep the stool, 80% of able-bodied patients continued their professional activities.

Introduction And Hypothesis: The urethra is surrounded by layers of smooth muscle, including inner longitudinal and outer circler muscles, as well as the skeletal muscle of the external urethral sphincter. However, the extent of these muscles and their relationship with the levator ani (LA) remain unclear. This study aimed to clarify the composition of muscle layers around the female urethra and their three-dimensional arrangements.
