Two boys with acute urinary retention were found to have a persistent pelvic mass after bladder decompression. Evaluation in each disclosed a large pelvic abscess secondary to a ruptured appendix. The diagnosis of appendicitis may be difficult and appendiceal abscess presenting with acute urinary retention in children has been reported previously in only 7 instances. History, physical examination, laboratory studies, and radiographic and ultrasonic evaluations should lead to the correct diagnosis, and surgical intervention restores normal voiding.
Three cases of acute penile injury are presented. Corpus cavernosography at the time of presentation was obtained, confirming the diagnosis. Radiologic evaluations including cavernosography and when indicated urethrography are discussed. Management modalities are reviewed including our preference for surgical exploration when a cavernosal tear has been documented.
Accurate diagnosis and successful management depend on knowledge of the anatomy and regulatory physiology of micturition. Incontinence is classified according to its mechanisms--passive incontinence, active incontinence with or without complete emptying, and overflow incontinence. Approaches to management include pharmacotherapy, surgical procedures and important steps in supportive care. This is a problem of any age. Educating the patient is essential.
