Case ReportsSpinal coning after lumbar puncture in prostate cancer with asymptomatic vertebral metastasis: a case report.
A 60-year-old man was admitted to our hospital for complete urinary retention. Prostate cancer was diagnosed and anti-cancer chemotherapy was administered. Regression of prostatic enlargement was appreciated and difficult urination improved. ⋯ Complete paralysis of both lower extremities occurred postoperatively. Computerized tomography and myelographic findings demonstrated complete subarachnoid block with an extramedullary spinal cord tumor. It was concluded that traction on the spinal cord producing neurological deterioration (spinal coning) occurred after removal of the cerebrospinal fluid by lumbar puncture.

Correlation of testicular color Doppler ultrasonography, physical examination and venography in the detection of left varicoceles in men with infertility.
High resolution color Doppler ultrasound is a noninvasive means of simultaneously imaging and evaluating the blood flow to the testes. To define the ability of color Doppler ultrasound to detect clinically evident as well as subclinical varicoceles men referred to our urology division with oligospermia and infertility underwent spermatic vein venography of the left testis if there was physical examination and/or color Doppler ultrasound evidence of a varicocele. ⋯ Of 5 patients with a normal physical examination but with color Doppler ultrasound evidence of a varicocele 4 had a confirmatory venogram, and 1 of 2 patients with a varicocele on physical examination and a normal Doppler ultrasound had a positive venogram. These data suggest that color Doppler ultrasound of the testis may more appropriately direct further invasive testing and therapy of infertile men than physical examination alone.
