Twenty-six male adult Noble (Nb) rats underwent unilateral left testicular torsion of 720 degrees. The testicles of the 6 control animals were immediately detorsed. The experimental animals were divided into 4 groups according to the surgical approach (abdominal vs. scrotal) and location where the torsed testicle was placed (abdomen vs. scrotum). After six(More)
Ectopic location of the vas deferens is a rare congenital abnormality that has a spectrum of presentations. Such cases have been associated with anorectal anomalies. Knowledge of distal Wolffian duct embryology may help to explain the developmental steps involved in these anomalies, as well as provide theories for the variations that may be encountered. Vas(More)
A total of 528 patients have been treated with radical prostatectomy and node dissection during the last five years. Correlation of clinical and pathologic staging will be presented. Over 85 percent of these patients had Gleason scores of 6 or less. Patients who had nerve-sparing surgery had a potency rate of over 60 percent post surgery.
Supravesical calcification noted on conventional radiography when associated with a bladder lesion has been considered nearly pathognomonic of the uncommon lesion, urachal adenocarcinoma. As the case reported here demonstrates, stippled microscopic calcification undetected by conventional means can be demonstrated uniquely by computed tomography with great(More)
To evaluate the usefulness of two new imaging modalities in the clinical staging of prostate cancer the following study was done. Twelve patients with biopsy-proved carcinoma of the prostate were evaluated preoperatively with magnetic resonance imaging (MRI) of the pelvis and transrectal ultrasound of the prostate. The main parameters evaluated were the(More)
Serum concentrations of prostate-specific antigen (PSA), prostate-specific acid phosphatase (PAP), and transrectal prostatic ultrasound were utilized in the evaluation of 193 men with various urologic disorders. Of the 193 patients, 48 had prostate cancer, and the other 145 included 5 with genitourinary neoplasms, 69 with benign prostatic hypertrophy, and(More)
Extravasation of irrigation fluid during percutaneous nephrostolithotomy is a major complication and can result in severe morbidity. We report 3 cases of peritoneal extravasation of irrigation fluid. Ventilatory difficulty and narrowed pulse pressure suggest intraperitoneal extravasation of irrigation fluid, which should be treated by rapid drainage of(More)
To investigate the role of guanosine 3':5'-monophosphate (cyclic GMP) in cultured cells we have measured guanylate cyclase and cyclic GMP phosphodiesterase activities and cyclic GMP levels in normal and transformed fibroblastic cells. Guanylate cyclase activity is found almost exclusively in the particulate fraction of normal rat kidney (NRK) and BALB 3T3(More)
