Laparoscopic partial cystectomy for treatment of adenocarcinoma of the urachus.

The treatment of choice for urachal carcinoma has traditionally been an open approach, either by radical cystectomy or the more recently adopted bladder-sparing approach of extended partial cystectomy and umbilectomy. We report for the first time a laparoscopic technique for an extended partial cystectomy with en bloc umbilectomy for the management of urachal carcinoma in a 41-year-old man.

Effect of neonatal circumcision on penile neurologic sensation.

Objectives: To evaluate penile sensory thresholds in neonatally circumcised and uncircumcised men.

Methods: We evaluated 125 patients, 62 uncircumcised men and 63 neonatally circumcised men. All patients completed the Erectile Function domain of the International Index of Erectile Function questionnaire.

Periurethral masses: etiology and diagnosis in a large series of women.

Objective: To describe the differential diagnosis of periurethral masses in a consecutive series extracted from a single tertiary urogynecologic practice database.

Methods: A patient database of a private urology and urogynecology practice with 1,950 women was searched for patients who were found to have a periurethral mass during the accrual dates of 1994 to 2002, and these records were reviewed for diagnostic testing and results. All women provided a history, completed a questionnaire, and underwent physical examination, voiding diary, cystoscopy, and videourodynamic testing; selected patients then underwent additional imaging.

Pad test by mail for home evaluation of urinary incontinence.

Aims: To present a simple, cost-effective, and convenient method of home pad test using the mail system and evaluating change in pad weight over time.

Materials And Methods: A series of nine kinds of commonly available commercial brands of urinary incontinence pads ranging from thin liners less than 10 g in dry weight to large diapers weighing over 100 g each were assembled. Two or three of each variety were individually weighed on an OHAUS LS2000 Portable Standard scale accurate to +/- 1 g.

Quantitative somatosensory testing of the penis: optimizing the clinical neurological examination.

Purpose: Quantitative somatosensory testing, including vibration, pressure, spatial perception and thermal thresholds of the penis, has demonstrated neuropathy in patients with a history of erectile dysfunction of all etiologies. We evaluated which measurement of neurological function of the penis was best at predicting erectile dysfunction and examined the impact of location on the penis for quantitative somatosensory testing measurements.

Materials And Methods: A total of 107 patients were evaluated.

Full-thickness human foreskin transplantation onto nude rats as an in vivo model of acute human wound healing.

Current wound-healing models do not fully duplicate the in vivo human environment. The feasibility of grafting human full-thickness foreskin onto nude rats, as a model of acute wound healing, was evaluated. Incisions were then created on the grafted skin, and wound healing was evaluated.

Ex vivo evaluation of human fetal membrane closure.

Background And Objective: This study compares stress and leak point pressure of human fetal membranes following closure with suture, laser welding, or a new tissue sealant, SynthaSeal.

Study Design/materials And Methods: Samples of fetal membrane were bisected and repaired with suture, laser welding with albumin solders, or a tissue sealant. Representative tissue samples were assessed by histology.
