Some criteria to attempt second side safely in planned bilateral simultaneous percutaneous nephrolithotomy.

Objectives: To determine the validity of some criteria that could guide in the decision to cancel or proceed with the second side of planned bilateral simultaneous percutaneous nephrolithotomy (bsPCNL).

Methods: Patients with an indication for bilateral PCNL were enrolled in this study. The operation was stopped at the end of the initial side if operative time was >180 min, the hemoglobin level was <11 g/dL, the hemoglobin decrease was >3 g/dL, the systolic arterial pressure was <100 mm Hg, the arterial oxygen saturation was <95%, the arterial blood pH was <7.

Bilateral kidney stones with ureteropelvic junction obstruction.

Background: A 56-year-old male with bilateral flank pain was admitted following diagnosis of bilateral kidney stone disease. He had previously undergone four separate pyelolithotomy sessions (two per kidney), the latest being 14 years prior. At presentation the patient had two stones in the right kidney and seven in the left kidney.

Bilateral disruption of corpus cavernosum with complete urethral rupture.

Penile fracture is a relatively rare condition. We report an unusual case of the bilateral disruption of the corpus cavernosum with complete urethral rupture resulting from blunt trauma during sexual intercourse. The subject underwent emergency surgery with preservation of erectile and voiding functions in the follow-up.

Role of penile electrodermal activity in the evaluation of autonomic innervation of corpus cavernosum.

Electrodiagnostic tests measuring the activities of cavernous smooth muscle and sudomotor structures of penile skin are used in order to evaluate autonomic innervation of the penis. Owing to closeness of these tissues, the interference of sympathetic activity during recording is a possibility. In this study, we investigated this possibility in 10 patients whose cavernosal tissues were destroyed during penile prosthesis implantation by comparing the pre- and postoperative penile skin electrodermal activities.
