Urine versus stent cultures and clinical UTIs.

Purpose: Current American Urological Association guidelines recommend pre-operative antimicrobial therapy based on prior urine cultures (UC); however, the role of stent culture (SC) in urologic practice is unclear. We examined whether UC and SC differed at the time of stent removal, as well as the association, microbiology, and timing of subsequent UTIs as related to SC.

Methods: This was a retrospective review of 159 patients with ureteral stents for indications of urolithiasis, benign stricture, malignant obstruction, and kidney transplant.

An improbable trifecta: Occurrence of xanthogranulomatous prostatitis, prostate cancer, and prostatic abscess in a single patient.

Xanthogranulomatous prostatitis (XGP) is a rare disease that can mimic the clinical and imaging findings of prostate cancer. Differentiation of these diseases is vital in order to offer the correct treatment. Histological examination of prostate tissue is the definitive manner in which XGP is distinguished from prostate cancer.

Hysteroscopic morcellator to overcome cervical stenosis.

Objective: To report a step-by-step technique to using a hysteroscopic morcellator to safely gain access into the intrauterine cavity in two patients with severe cervical stenosis and concomitant intrauterine pathology.

Design: Video article introducing the hysteroscopic morcellator for overcoming severe cervical stenosis.

Setting: Academic-based practice.

Metroplasty to treat chronic pelvic pain resulting from outflow tract müllerian anomalies.

Chronic pelvic pain can result from noncommunicating uterine cavities in patients with müllerian anomalies. Traditional management has been to resect the noncommunicating uterine horn. Two cases are described.

Preconditioning by subinotropic doses of ouabain in the Langendorff perfused rabbit heart.

Short exposure to low concentrations of digitalis drugs like ouabain protects the rat heart against ischemia/reperfusion injury through the activation of the Na/K-adenosine triphosphatase (ATPase)/Src receptor complex and subsequent stimulation of key intracellular cardioprotective signals. Rat Na/K-ATPase, however, is relatively insensitive to digitalis, and it is not known if similar results could be obtained in species with higher sensitivity. Thus, to determine whether ouabain pretreatment protects against ischemic injury and activates the Na/K-ATPase signaling cascade in a species with cardiac glycoside sensitivity comparable to humans, the present study was conducted in the rabbit model.
