Lacuna magna in 6 boys with post-void bleeding and dysuria: alternative approach to treatment.

Six boys from 8 to 17 years old presented with blood dripping from the meatus at the termination of urination, spotting of blood on underwear and/or distal penile dysuria. Repeat urinalyses and cultures were negative, and evaluation included a voiding cystourethrogram. Diagnosis was lacuna magna in the area of the fossa navicularis, which was confirmed by cystoscopy.
