Neuroanatomy of the pelvis: implications for colonic and rectal resection.

Purpose: Urinary dysfunction remains a common complication of radical pelvic surgery, particularly after abdominoperineal resection. In treating rectal carcinoma, the extent of primary resection and lymphadenectomy are major determinants in the degree of postoperative urologic morbidity.

Methods: Twelve male and eight female hemipelves from fresh cadavers were dissected with reference to the neuroanatomy of the lower genitourinary tract.

Penectomy: a technique to reduce blood loss.

Objectives: Hemorrhage is potentially a major complication of partial or total penectomy that may result in the need for blood transfusion. The surgical technique of penectomy was evaluated to determine whether modifications may lead to reduced blood loss.

Methods: A simple technique was used to minimize blood loss during penectomy.

Urologic emergencies. Trauma injuries and conditions affecting the penis, scrotum, and testicles.

Urologic emergencies involving the penis, scrotum, and testicles include priapism, paraphimosis, testicular torsion, and Fournier's gangrene. Familiarity with the signs and symptoms of these conditions can lead to prompt diagnosis. Special care is needed in differentiating testicular torsion from the more common condition of epididymitis.

Urologic emergencies. Conditions affecting the kidney, ureter, bladder, prostate, and urethra.

Prompt, thorough evaluation is needed when patients present with symptoms of renal colic, acute urinary retention, prostatitis, pyelonephritis, and other urologic emergencies. Primary care physicians have an important role in initial workup and treatment. Once the diagnosis is determined, urologic consultation may be necessary for definitive treatment.
