Endometrioid carcinoma of prostate.

A prostatic tumor that was excised from a sixty-two-year-old man was found histologically to resemble papillary endometrial carcinoma. A specimen of this prostatic endometrioid carcinoma tested positive for prostate-specific antigen and focally positive for mucin, confirming the prostatic epithelial origin of the tumor. A review of the literature indicates that tumors of this type are best approached as a standard acinar adenocarcinoma of the prostate.

Mucinous adenocarcinoma of the prostate.

A case of mucinous adenocarcinoma of the prostate that was diagnosed with the aid of prostate-specific antigen immunoperoxidase staining is reported. Focal areas of the tumor, which were morphologically similar to the remainder of the tumor, stained with neuron-specific enolase by an immunoperoxidase technique and with the Grimelius stain. This tumor is best thought of as a variant of the classic acinotubular adenocarcinoma of the prostate with well-differentiated cells that secrete mucin, rather than as a completely different type of cancer, as proposed previously.

Allergic reaction to protamine: a late complication of elective vasectomy?

Nucleoprotamines are a normal component of human sperm cells. Antibodies against these protamines develop in 22 to 33 per cent of patients undergoing elective vasectomy. These antibodies, in turn, have been shown to cross-react with medicinal protamines, which are extracted commercially from the testes of salmon and certain other fish. This cross-reactivity against protamines raises the possibility that patients who have undergone elective vasectomy may be at increased risk of an allergic reaction developing if they are later exposed to protamine as a medication. Since medicinal protamines currently enjoy widespread clinical use, this information should be borne in mind by those clinician using protamine and by urologists when counselling patients concerning elective vasectomy for sterilization.

The sonographic appearance of fluid in the prevesical space.

A fluid collection within the retropubic space has a characteristic sonographic contour which, when combined with a partially distended bladder, resembles a yoke over a bell. The fluid conforms to the anterior convexity of the bladder. This configuration is distinct from that of ascites or a lymphadenectomy-related lymphocele.

Triamterene stone: advantage of crystallographic analysis.

Microscopic crystallographic analysis of renal calculi provides clinically useful information concerning the pathogenesis of stone disease and is, therefore, superior to conventional chemical analysis of stones. The advantages of crystallography, performed at a centralized, experienced stone-analysis center, are highlighted by the recent discovery of triamterene deposits in kidney stones. Deposits of other medications and their metabolites have also been uncovered. Two case reports are presented, the clinical implications of these and related findings are discussed.

Ataralgesia in outpatient urology. Clinical evaluation.

The combination of fentanyl citrate (Sublimaze) and diazepam (Valium) was evaluated for efficacy of analgesia, sedation, and safety in 1,008 predominately outpatient urologic procedures. These procedures included prostate biopsies, basket extractions of ureteral calculi, internal urethrotomies, and cystourethroscopies. Ninety-two per cent were judged to be successful with regard to adequate tranquilization and relief of pain. No detrimental effects were seen with the recommmended method and dosage. This drug combination provides the clinician with an effective and safe alternative to local, general, or spinal anesthesia for many routine urologic procedures and allows them to becom true office procedures.
