Comparative StudyThe extraperitoneal approach and subcutaneous emphysema are associated with greater absorption of carbon dioxide during laparoscopic renal surgery.
We investigated the association of carbon dioxide absorption with the approach (transperitoneal versus extraperitoneal) and other factors during laparoscopy. ⋯ Carbon dioxide absorption during laparoscopic renal surgery increases with time, and is greatest in patients treated through an extraperitoneal approach and in those with subcutaneous emphysema. Nonetheless, with attentive ventilatory management adverse sequelae of hypercapnia can be avoided.

Management of spinal cord injured patients by indwelling suprapubic catheterization.
We review the urological complications in spinal cord injury patients treated with suprapubic catheterization. ⋯ Suprapubic catheterization is an effective and safe alternative form of bladder management in select patients with spinal cord injury.

We treated 30 patients with Fournier's gangrene during a 15-year period. Data were collected on demographics, medical history, admission signs and symptoms, physical examination, admission laboratory studies and bacteriology. The timing and degree of surgical débridement as well as antibiotic therapy were also reviewed. ⋯ Deviation from homeostasis is the most important parameter predictive of outcome and not the extent of disease or performance of surgical débridement. The Fournier's gangrene severity index is an objective and simple method to quantify the extent of metabolic aberration that may be used to predict outcome. We recommend the use of the Fournier's gangrene severity index when evaluating therapeutic options and reporting results.

Comparative StudyTherapeutic outcome of primary aldosteronism: adrenalectomy versus enucleation of aldosterone-producing adenoma.
Our followup study of 48 patients with primary aldosteronism concerns the results of 2 different operative methods. After preoperative localization of the unilateral solitary tumor 22 patients underwent unilateral adrenalectomy and 26 underwent enucleation of aldosterone-producing adenoma. Both operative methods improved hypertension, hypokalemia, the low urinary sodium-to-potassium ratio, suppressed plasma renin activity, high plasma aldosterone concentration, high urinary aldosterone excretion and high urinary kallikrein excretion in similar orders of magnitude for 5 years. ⋯ After respective operations, responses of plasma aldosterone concentration to angiotensin II infusion and of plasma cortisol to adrenocorticotropic hormone administration in the aldosterone-producing adenoma enucleation group were more sensitive than those in the adrenalectomy group. There was no remission of recurrent hyperaldosteronism in either group throughout the study. These results suggest that angiotensin II induces aldosterone release by an activation of tumor uninvolved cortical cells and that the enucleation of aldosterone-producing adenoma is more preferable than unilateral adrenalectomy.

Comparative StudyComparison of bladder management complication outcomes in female spinal cord injury patients.
A total of 70 female spinal cord injury patients was retrospectively analyzed for outcomes of long-term bladder management. Three groups were defined: 1) 23 patients on intermittent catheterization, 2) 25 treated by reflex voiding and incontinence padding, and 3) 22 with an indwelling catheter. Mean years of using the specific bladder management technique were 8.5 +/- 4.7, 15.8 +/- 7.3 and 16.7 +/- 9.0 for the 3 groups, respectively. ⋯ The differences among the groups remained significant (p < 0.00001). Additional analyses showed highly significant differences between the catheter group and the other 2 groups (intermittent catheterization p = 0.0009 and padding p = 0.0005), and a difference that approached significance between the intermittent catheterization and padding groups (p = 0.085). The results strongly support intermittent catheterization as the optimal management of female patients following spinal cord injury given that other factors, in particular independent hand function or the need for appropriate assistance, are considered.
