Voiding dysfunction in institutionalized elderly men: the influence of previous prostatectomy.
Voiding problems, either retention or incontinence, affect a majority of institutionalized elderly patients. Although impaired cerebral function is the dominant cause, those patients who had undergone prior transurethral prostatectomy were more vulnerable to the development of voiding dysfunction than those who had not. Moreover, the elimination of obstruction by prostatectomy did not produce the expected shift from indwelling catheterization to condom drainage.

The urologic care of the spinal cord injury patient.
From 1974 to 1979, 141 acute spinal cord injury patients in the acute phase were managed by sterile, intermittent catheterization without complication. Of these patients 101 have been followed to the present. We used urodynamic criteria to determine whether these patients should be in retention on intermittent self-catheterization, or voiding with or without an appliance. When compared to a matched control group managed by indwelling catheterization in the acute phase and conventional criteria in the rehabilitation phase, 1 of 10 complications and 1 of 7 infections occurred in the study group. This analysis confirms that intermittent catheterization in the acute and rehabilitation phases, and the use of urodynamic criteria to follow lower tract management to achieve a low pressure voiding system represent major advances in the care of the urinary tract in patients with acute spinal cord injury.

Unexplained hematuria.
In 270 consecutive patients who presented with hematuria over a 12-month period, complete visualization of the urinary tract by urography and cystoscopy indicated a causative lesion in over 90%. Where a cause could not be found on the first presentation, the initial evaluation was repeated within 4 months, revealing the previously missed diagnoses in four patients. Of patients who bled while receiving anticoagulants, 17% were found to have an important underlying cause other than anticoagulant therapy. Despite repeated evaluation, and in many instances more elaborate investigation with angiography, computerized tomography and ultrasonography, no reasonable diagnosis could be made in 6% (12% of those with microscopic hematuria, 4% with gross hematuria). One hundred and fifty-nine patients with unexplained hematuria, seen between 1975 and 1983, were studied. The triad of "gross, total and painless" was present in 15%. Patients who bled heavily from one kidney without any apparent cause benefited from orally administered epsilon aminocaproic acid.
