Bulbar elongation anastomotic meatoplasty (BEAM) for subterminal and hypospadiac urethroplasty.

Purpose: All urethral reconstruction that involves substitution has an inherent ongoing incidence of restenosis with time. Anastomotic restoration of urethral continuity naturally obviates these complications but to achieve its potential of a long-term stricture-free success rate that approaches 100% circumstances must be ideal and the reconstructive surgical technique must be meticulous. If the critical indications for anastomotic reconstruction are overextended, complications inevitably increase. Considerable additional urethral length is required to overcome the terminal atretic deficiency associated with hypospadias and create a tension-free anastomotic neomeatoplasty. Mobilization and advancement of the penile urethra alone are rarely sufficient to achieve this without causing penile chordee. We describe the details of bulbar elongation anastomotic meatoplasty (BEAM) that we have been using for approximately the last 8 years.

Materials And Methods: The only part of the urethra that can be mobilized to provide extra length for anastomotic urethroplasty without creating penile curvature chordee is the bulbar urethra. Full length mobilization of the whole length of the bulbar urethra through a perineal incision provides 2 to 2.5 cm. of tension-free lengthening in children and 4 to 5 cm. in adults. Thus, many subterminal urethral deficiencies can be resolved by bulbar elongation anastomotic meatoplasty when the total extent of the urethral deficiency is not disproportionally long. We performed bulbar elongation anastomotic meatoplasty in 12 patients 2 to 25 years old.

Results: At a followup of 2 to 7 years the neomeatus is functionally and cosmetically satisfactory in all cases with no long-term complications or chordee.

Conclusions: When circumstances are appropriate, bulbar elongation anastomotic meatoplasty is a preferable alternative to some of the current substitution procedures. Once established, anastomotic reconstructions are generally stable in the long term.
