PURPOSE To assess the accuracy of resistive index (RI) in the diagnosis of obstruction. MATERIALS AND METHODS The time course of RI and its relationship to intrapelvic pressure were measured in 6 dogs following unilateral obstruction. RESULTS Changes in RI 1) occurred as early as 1/2 hour after acute obstruction, 2) only reached diagnostic sensitivity(More)
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)
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.
Aquifer–atmosphere interactions can be important in regions where the water table is shallow (<2 m). A shallow water table provides moisture for the soil and vegetation and thus acts as a source term for evapotranspiration to the atmosphere. A coupled aquifer–land surface–atmosphere model has been developed to study aquifer–atmosphere interactions in(More)
Bladder drainage of the pancreatic graft remains the most common technique in pancreatic transplantation. Graft and patient survival is superior to duct injection and bowel drainage techniques. However, several urological complications develop as a result of bladder drainage. We report 6 cases of the dysuria syndrome after combined kidney/pancreas(More)
The histologic effect of unilateral torsion on the contralateral testicle in adult Noble rats was examined. Utilizing detorsion or orchiectomy at 3 hours and 24 hours after torsion, the effect of early and late treatment of these changes was reviewed. The histologic changes consisted of loss of tubular spermatozoa, clumping of chromatin within the(More)
Over a 4 1/2 year period, 1,940 asymptomatic men were entered in a prostate cancer detection program consisting of digital rectal examination (DRE), prostate-specific antigen (PSA), and transrectal prostate ultrasound (TRUS). Four hundred and sixteen biopsies were performed resulting in the diagnosis of 79 cancers; 82% had clinically organ confined tumors.(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)
In brief: Contusions and minor lacerations, the most common renal injuries, require conservative treatment, and the athlete must refrain from strenuous activities for 2 to 3 weeks. Most patients with hematuria have a renal contusion at most and do not need contrast studies. Underlying renal abnormalities, pyelonephritis, and stone disease are occasionally(More)
Spontaneous rupture of normal renal parenchyma must indeed be rare. Virtually all patients in this paper had a significant abnormality that presented with bleeding. Our Case 5 is the only one without a clear underlying pathologic entity. We should stress the high incidence of associated disease in kidneys that bleed "spontaneously" and therefore the need(More)
