A patient presented at 29 weeks' gestation with severe hemolytic anemia. She was subsequently diagnosed as having renal cell carcinoma and had a radical nephrectomy at 31 weeks' gestation, which demonstrated stage I disease. This was followed by a normal vaginal delivery of a healthy infant at term and complete resolution of her anemia. This unusual(More)
During 26 months 200 consecutive patients with fracture of the bony pelvis were evaluated and treated for urological injury. There was no correlation between the extent of pelvic injury and degree of hematuria but hematuria was present in all patients with a urological injury. All urological injuries occurred with anterior arch fractures. The over-all(More)
A randomized, prospective, double-blind, placebo-controlled study was conducted at 7 clinical centers on 148 patients. Patients received orally either 100 mg. pentosanpolysulfate (a synthetic polysaccharide) 3 times per day or a placebo. Of the patients on drug therapy 32% showed significant improvement compared to 16% of those on placebo (p = 0.01). This(More)
The neuromorphology and neuropharmacology of the human penis are only briefly described in literature. The present study was undertaken to define the adrenergic and cholinergic neuromorphology of the human corpus cavernosum (CC) and corpus spongiosum and to evaluate the in vitro response of the CC to pharmacologic stimulation. Human penile tissue was(More)
A total of 3 renal transplant recipients who were candidates for urinary diversion underwent successful transplantation using a planned program of intermittent clean catheterization. The urinary tract dysfunction was caused by a lower motor neuron neurogenic bladder, prune belly syndrome and myelodysplasia. The patients remain dry between catheterizations(More)
Transient blindness was seen in 2 patients undergoing transurethral resection (TUR) of the prostate as the initial symptom of a severe TUR reaction. Cerebral edema of the occipital cortex is the most probable mechanism. Both fully recovered their vision when appropriately treated. Patients with visual disturbances during transurethral prostatectomy should(More)

Bladder dysfunction in the elderly is an enormous public health problem. Laboratory research using animal models has to date not yielded clinically useful new information. Demographic and urodynamic studies in selected elderly patients indicate that neurological disease and bladder outlet obstruction are the primary causes for voiding dysfunction. The(More)
OBJECTIVE The tissue rim sign-a rim or halo of soft-tissue attenuation seen around the circumference of an intraureteral calculus on unenhanced axial CT-has been described as useful in differentiating ureteral calculi from extraurinary abdominal or pelvic calcifications. The purpose of this study was to determine the prevalence of the tissue rim sign in(More)
PURPOSE To evaluate the use of helical computed tomography (CT) without contrast material enhancement for prediction of a favorable outcome in ureterolithiasis. MATERIALS AND METHODS CT studies were reviewed in 69 patients with a single ureteral stone not located at the ureteropelvic junction. CT findings (tissue rim sign, hydronephrosis, perinephric fat(More)
We evaluated 50 men who suffered a total disruption of the posterior urethra in conjunction with a fractured pelvis. The urethral disruption was treated with immediate placement of a suprapubic cystostomy and delayed one-stage urethroplasty. Subsequently, 15 required at least one visual urethrotomy and three underwent one urethral dilatation. All 50 now(More)
