Use of gadolinium-DTPA-enhanced MRI to characterize renal mass in patient with renal insufficiency [Case Report]
A patient with chronic renal insufficiency was found to have an indeterminate renal mass after renal ultrasound, non-contrast CT, and non-contrast MRI studies. The mass was correctly diagnosed as an enhancing tumor with gadolinium-DTPA-enhanced magnetic resonance imaging
Multiphasic diagnostic evaluation of arteriogenic, venogenic, and sinusoidogenic impotency. Value of noninvasive tests compared with penile duplex ultrasonography
Fifty patients with a mean age of fifty-five years (range 25 to 75 years) in whom vasculogenic impotency was suspected clinically were evaluated to determine the type of vascular lesion involved: arterial insufficiency, venous leak, or sinusoidal dysfunction. All patients underwent first, noninvasive diagnostic tests including penile brachial index, penile brachial subtraction index, and penile plethysmogram, followed by penile duplex ultrasonography with papaverine and phentolamine injection. Patients with abnormal ultrasonography were divided into two groups: One group with suspected sinusoidal dysfunction and those with either arteriogenic or venogenic insufficiency but not considered candidates for surgery; they were not subjected to further studies. Another group with suspected proximal arteriogenic lesions and those with suspected venous leakage considered candidates for surgical correction were subjected to angiography and cavernosometry-cavernosography, respectively. The findings of the noninvasive tests were compared with those provided by the invasive tests. The results indicated that noninvasive tests can predict whether or not impotency is arteriogenic in approximately 90 percent of cases. The noninvasive tests, however, were less accurate in predicting venogenic and sinusoidogenic impotency, for which penile duplex ultrasonography seems to be the choice
Recurrent ovarian theca granulosa cell tumor presenting as bladder neoplasm [Case Report]
Perirenal candidial abscess [Case Report]
Perirenal candidial abscesses are rare, with few well-documented cases in the literature. We describe a case of a perinephric abscess treated with amphotericin B and nephrectomy
Transrectal ultrasound in early detection of clinical stage A prostate cancer [Case Report]
A group of 40 select men were studied to assess the value of transrectal ultrasound in the early detection of prostate cancer. All had a benign digital rectal examination and had either irritative lower tract symptoms, hematospermia, microhematuria, or an elevated acid phosphatase. Of the men, 28 had an abnormal ultrasound and underwent a directed prostate needle biopsy to assess the ability to detect clinical Stager A cancer. Eleven men (40%) were found to have cancer, all having hypoechoic lesions. The remainder were found to have benign prostatic hypertrophy (BPH) with hyperechoic lesions predominating (88%). Our results suggest that transrectal ultrasound is a useful and sensitive method for the detection of prostate tumors not clinically evident on digital rectal examination in select patients
Ureteropelvic junction obstruction during the first year of life
Over the past three years, 28 children less than one year of age, were operated on for ureteropelvic junction obstruction. Our results demonstrate that congenital hydronephrosis most commonly presents antenatally, and that early postnatal correction can be performed safely. The high surgical success rate, with a relatively short hospital stay (3-4 days), is attributed to early diagnosis, when the pelviureteral tissues are relatively healthy and nephron maturation is at maximum. The practice of delaying surgical correction of an obstructed hydronephrotic kidney on the basis of 'stable' renal function is unwarranted, since it denies such kidneys their full potential for recoverability
MAGPI hypospadias repair: ambulatory versus inpatient surgery
Over a one-year period, 96 consecutive children with distal hypospadias underwent mental advancement and glanuloplasty (MAGPI) for hypospadias repair. In a prospective study, 56 were operated on as inpatients, and 40 underwent repair as outpatients. It was determined that MAGPI can be performed safely and cost-effectively on an ambulatory basis.

Paratesticular desmoid tumor [Case Report]
A primary intrascrotal mass clinically mimicking a testicular tumor was found to be a desmoid tumor originating from the spermatic cord. To our knowledge, this is the first reported case of a paratesticular desmoid tumor.
