Clinical experience with 99mTc-polyphosphate scintigraphy in more than 200 patients with suspected stress fractures is presented. Stress fractures occur in bone which has been weakened as a result of accelerated physiological change induced by excessive muscular and mechanical activity. Unlike traumatic fractures, they are not accompanied by radiographic abnormality early in their course. Bone scintigraphy is sensitive enough to detect the physiological alterations found in stress fractures and was responsible for decreased morbidity in this series of patients due to early diagnosis.

Bladder neck dysfunction has been evaluated in 16 male patients. The efficacy of the traditional investigative methods for this entity is questionable and the value of video-urodynamics for definitive diagnosis is presented. The ability of the condition to masquerade as prostatis is apparent and treatment by unilateral bladder neck incision is proposed.

Ultrasound is being used with increasing frequency in the evaluation of the male reproductive tract. To detect abnormalities, it is important to have a comprehensive understanding of the normal anatomy and normal variations. In this article, the ultrasound anatomy of the scrotum, penis, prostate, and seminal vesicles is presented. Because ultrasound is a very visual process, the anatomy is presented not only with text, but also through the liberal use of ultrasound images and associated diagrams. Ultrasound is both an operator‐ and equipment‐dependent procedure and, where appropriate, we have included technical discussions regarding ultrasound equipment and settings. © 1996 John Wiley & Sons, Inc.

Radioactive implants migrated after brachytherapy for localized prostate cancer in 29% of the patients who underwent post-procedure radiography. There did not appear to be a pattern to the seed distribution. However, while the incidence was not negligible, no patient appeared to have any acute pulmonary symptoms. Therefore, while the migration of radioactive implants to the chest is a real phenomenon, it appears to have no adverse clinical consequences in the early post-procedure period.
