Leiomyosarcoma of the renal vein.

The preoperative diagnosis for primary leiomyosarcoma of the renal vein, an extremely rare tumor, is difficult. The tumor predominantly occurs in women and on the left side. Its natural history is toward distant metastases and a poor 5-year survival rate.

External genitalia gunshot wounds: a ten-year experience with fifty-six cases.

Objective: To determine the appropriate methods for the diagnosis and management of gunshot injuries to the external genitalia.

Adult acute idiopathic scrotal edema.

We report here a rare case of adult acute idiopathic scrotal edema (AISE). Its characteristics and management are the same for adults as for prepubertal boys. AISE typically affects prepubertal boys, with an acute onset of a relatively painless scrotal erythema and subcutaneous edema, which resolves spontaneously, without sequela, in 1 to 3 days.

Ureteral injuries from penetrating trauma.

Twelve patients with ureteral injuries from stab or gunshot wounds were evaluated. All 12 underwent surgical exploration on admission. None of the injuries were diagnosed preoperatively.

Current findings and future research avenues in the study of interstitial cystitis.

This article reports the progress made in the last several years of investigations into possible pathogenic processes that lead to the development of interstitial cystitis. The evidence presented here asserts that bladder mucin is functionally intact in interstitial cystitis and that the permeability of the afflicted patient's bladder is not greater than normal.
