Use of a surgical helmet system to minimize splash injury during percutaneous renal surgery in high-risk patients.

The transmission risk to surgeons performing percutaneous renal surgery on patients who are infected with human immunodeficiency virus/acquired immunodeficiency syndrome, hepatitis B, or hepatitis C is unknown. A recent study found 55% of surgeons' masks contain evidence of blood splash contamination after percutaneous nephrolithotomy. While the risk of infectious disease transmission to the surgeon after mucocutaneous exposure is unknown, the incapacitating disease these pathogens cause can have a devastating and permanent effect on a surgeon's career. We describe our use of a surgical helmet system when performing percutaneous renal surgery on high-risk patients to minimize risk of splash injury and transmission of blood-borne pathogens.

Female urethral stricture disease.

Female urethral stricture disease is a rare entity. The most common etiologies are traumatic injury, iatrogenic injury, and inflammatory disease resulting in periurethral fibrosis. Hallmark symptoms are frequency and urgency, and may also be dysuria, hesitancy, slow stream, incontinence, and recurrent urinary tract infections. Female bladder outlet obstruction is a difficult entity to define, and the subset representing stricture disease may also be elusive. The diagnosis of female urethral stricture disease is usually based on symptoms, meatal appearance, and difficult instrumentation of the patient. Other testing, such as urodynamics, voiding urography, or cystoscopy, may be helpful. Treatment options are conservative management with dilatation, endoscopic treatment, or open repair with various tissue flaps or grafts. Considerable controversy surrounds the efficacy of urethral dilatation in women with voiding dysfunction.

Development and validation of the fecal incontinence and constipation quality of life measure in children with spina bifida.

PURPOSE: Fecal incontinence and constipation in children with spina bifida are recognized to impact quality of life. Most disease specific quality of life instruments on fecal incontinence target adults and/or children without neuropathic bowel. We developed an instrument to evaluate bowel function and its impact on quality of life in children with spina bifida and their caregivers. MATERIALS AND METHODS: A 51-item questionnaire termed the FIC QOL (Fecal Incontinence and Constipation Quality of Life) survey was developed from expert opinion, patient interviews, and modification of previously published adult and pediatric studies for nonneuropathic bowel dysfunction. The items are divided into 7 quality of life factor groupings, including bowel program, dietary management, symptoms, travel and socialization, family relationships, caregiver emotional impact and financial impact. The questionnaire was given to caregivers of children with and without spina bifida. Discriminant validity was evaluated by comparing the spina bifida and control groups. Test-retest reliability was evaluated by having 41 patients complete 2 surveys within 4 to 6 weeks. RESULTS: Comparing questionnaires from 92 index patients and 52 controls showed a statistically significant difference for all 7 quality of life factor groupings. The FIC QOL instrument objectively demonstrated the negative impact of fecal incontinence and constipation on quality of life in these families. Comparing 82 questionnaires at 2 time points demonstrated the reliability of all FIC QOL questions. CONCLUSIONS: The FIC QOL instrument provides a valid and reliable measure of the effect of fecal incontinence and constipation on the quality of life of caregivers and their children with spina bifida.

Intermediate-term outcome of the simplified laparoscopic antegrade continence enema procedure: less is better.

PURPOSE: The Malone antegrade continence enema procedure revolutionized the surgical management of fecal incontinence. Open and laparoscopic antegrade continence enemas are often performed with cecoplication and mesenteric manipulation. Since our initial laparoscopic antegrade continence enema description, we have simplified our technique. We present our series of laparoscopic antegrade continence enema procedures, discuss technique and outcomes, and review the literature. MATERIALS AND METHODS: We retrospectively reviewed children who underwent laparoscopic antegrade continence enema between 2001 and 2007. Outcome measures included operative time, length of stay, stomal complications and resolution of incontinence or constipation. Using an umbilical port and 1 to 2 additional ports, the appendix was mobilized to allow transposition to the umbilicus. No cecoplication was performed. The appendix was not straightened unless catheterization was difficult. RESULTS: A total of 22 patients (mean age 7.8 years) underwent laparoscopic antegrade continence enema. Of the patients 21 were discharged home on postoperative day 1. Mean operative time was 65 minutes (range 30 to 116). In the last 10 patients only 1 working port was used. No perioperative complications were encountered. Mean followup was 24 months (range 1 to 68). Constipation and fecal incontinence resolved in all cases. No patient experienced stomal complications. One obese patient with kyphosis could not pass the catheter beyond the mid appendix at 1 month postoperatively. She had the same problem 1 month following open antegrade continence enema with cecoplication. CONCLUSIONS: Laparoscopic antegrade continence enema is an effective means of treating intractable fecal incontinence and constipation. Our technique of using in situ appendix without cecoplication requires minimal mobilization and manipulation of the blood supply. Secondary ischemia, adhesions and scar formation are reduced, alleviating the most common complication, stomal stenosis. Our results show that cecoplication is not necessary to maintain stomal continence.

Limited anterior cystotomy: a useful alternative to the vaginal approach for vesicovaginal fistula repair.

In developed nations, vesicovaginal fistulas are most commonly encountered as a complication after gynecologic surgery. Most fistulas are corrected using a transvaginal approach; however, complicated cases often require intraabdominal repair. A novel abdominal approach is described, using a small anterior cystotomy and omental pedicle interposition.

Artificial urinary sphincter placement in elderly men.

OBJECTIVES: To evaluate the outcomes of primary artificial urinary sphincter (AUS) placement for the treatment of postprostatectomy stress urinary incontinence in patients aged 75 years or older at surgery. METHODS: From September 1987 through June 2005, 33 men aged 75 years or older underwent AUS insertion for postprostatectomy stress urinary incontinence. Through retrospective chart review and personal/family interview, the patients' outcomes with regard to continence, complications, and the need to deactivate the AUS for medical or social reasons were determined. RESULTS: Four patients were lost to follow-up and were excluded from the analysis. The mean patient age was 77.6 years (range 75 to 83). The average follow-up was 5.0 years (range 1 to 11). After AUS insertion, the mean pad use improved from 6.7 (range 3 to 10) to 0.8 (range 0 to 2) per day. Overall, 16 (55%) of 29 men reported no complications. AUS revision was necessary in 4 men (14%), and sphincter removal in 4 (14%). Six men (21%) required deactivation of the implant because of poor overall health an average of 47 months after placement. The "success" rate improved to 72% (21 of 29 men) when cuff deactivation without revision or removal was not considered a complication. CONCLUSIONS: In our study, elderly men did well after AUS placement for postprostatectomy stress urinary incontinence. The procedure should not be withheld solely on the basis of the age of the patient.

Early outcomes of mid-urethral slings for female stress urinary incontinence stratified by valsalva leak point pressure.

AIMS: To assess the early results of mid-urethral slings placed via the transobturator approach (TVT-O) for stress urinary incontinence (SUI) in women with high (>60 cm H(2)O) and low (60 cm H(2)O) or low (60. CONCLUSIONS: With limited follow up, TVT-O appears to be a safe and effective surgical treatment for female SUI producing excellent results in patients with VLPP >60 cm/H(2)0. Patients with low VLPP may consider conventional, retropubic mid-urethral slings or other procedures as treatment for SUI.

Robot-assisted laparoscopic nephroureterectomy.

BACKGROUND: Laparoscopic nephroureterectomy for upper-tract urothelial tumors is a minimally invasive approach that parallels the open technique in oncologic efficacy. Multiple approaches to manage the distal ureter have been described. We developed a new technique using the daVinci robot system to perform a transvesical excision of the distal ureter and bladder cuff. PATIENTS AND METHODS: Ten consecutive patients with upper-tract urothelial cancer underwent a laparoscopic nephroureterectomy. The daVinci robot was docked through the umbilical, ipsilateral lateral rectus, and an additional contralateral lateral rectus port. The bladder was clam-shelled in a coronal orientation at the dome and the distal ureterectomy performed. RESULTS: Our technique was successful in all ten patients. The mean operative time for the entire case was 4.4 hours. The average hospital stay was 3 days. CONCLUSIONS: Robot-assisted laparoscopic nephroureterectomy is a safe, minimally invasive approach to upper- tract urothelial cancer that reduces the technical challenge of excision of the distal ureter.

Vesicostomy revisited: the best treatment for the hostile bladder in myelodysplastic children?

OBJECTIVE: To evaluate the effects of vesicostomy on the urinary tract of myelodysplastic children in whom conservative bladder management with clean intermittent catheterization (CIC) has failed to preserve upper and lower urinary tract function. PATIENTS AND METHODS: Sixteen children with myelodysplasia underwent vesicostomy. Indications included worsening hydronephrosis, vesico-ureteric reflux (VUR), recurrent urinary tract infections (UTIs), and increasing renal insufficiency despite CIC and/or difficulty with CIC. The mean (range) age at vesicostomy was 36.5 (9-82) months and the follow-up 7.4 (2-16) years. RESULTS: Hydronephrosis resolved or improved in 12 of 14 children, the incidence of UTI decreased to one or fewer per year in 10, VUR resolved or improved in nine, and renal function improved or stabilized in six of seven patients. One patient initially presented with renal insufficiency and subsequently required dialysis despite vesicostomy. Complications occurred in three of 15 children, and included stomal stenosis and bladder calculi. The vesicostomy was closed in six patients after a mean of 4.4 (1.5-9) years. Four of these patients required concomitant bladder augmentation. CONCLUSIONS: Vesicostomy in myelodysplastic children is effective in preventing and/or resolving the deleterious consequences of a 'hostile' bladder. The procedure is uncomplicated, well tolerated, reversible and should be considered in managing children in whom conservative management by CIC has failed.
