    Title Variability of Urodynamic Parameters in Patients with Overactive Bladder.
    Date February 2012
    Journal Neurourology and Urodynamics
    Excerpt

    To report interpatient, intrapatient, and study site variability of urodynamic study (UDS) parameters in patients with overactive bladder (OAB).

    Title Bladder Dysfunction in Mice with Experimental Autoimmune Encephalomyelitis.
    Date February 2009
    Journal Journal of Neuroimmunology
    Excerpt

    The vast majority of patients with multiple sclerosis (MS) develop bladder control problems including urgency to urinate, urinary incontinence, frequency of urination, and retention of urine. Over 60% of MS patients show detrusor-sphincter dyssynergia, an abnormality characterized by obstruction of urinary outflow as a result of discoordinated contraction of the urethral sphincter muscle and the bladder detrusor muscle. In the current study we examined bladder function in female SWXJ mice with different defined levels of neurological impairment following induction of experimental autoimmune encephalomyelitis (EAE), an animal model of central nervous system inflammation widely used in MS research. We found that EAE mice develop profound bladder dysfunction characterized by significantly increased micturition frequencies and significantly decreased urine output per micturition. Moreover, we found that the severity of bladder abnormalities in EAE mice was directly related to the severity of clinical EAE and neurologic disability. Our study is the first to show and characterize micturition abnormalities in EAE mice thereby providing a most useful model system for understanding and treating neurogenic bladder.

    Title Management of Iatrogenic Foreign Bodies of the Bladder and Urethra Following Pelvic Floor Surgery.
    Date October 2008
    Journal Neurourology and Urodynamics
    Excerpt

    OBJECTIVE: Literature regarding the management of iatrogenic foreign body in the bladder and urethra following female pelvic reconstructive surgery, especially mesh erosion, are sparse. We present our recent experience with the removal of iatrogenic foreign bodies from the bladder and urethra and propose a treatment algorithm. METHODS: A retrospective review yielded 22 patients with iatrogenic foreign body in the bladder or urethra between 1/1998 and 12/2005. Presenting complaints, cystoscopic findings, operative techniques, and outcomes were reviewed. RESULTS: Source surgery of the iatrogenic foreign bodies included bladder suspension in 9 patients, synthetic sling in 11 patients, abdominal sacrocolpopexy and porcine dermis sling in 1 patient each. The majority of patients presented with multiple voiding dysfunctions including overactive bladder symptoms (11), incontinence (5), chronic pelvic or urethral pain (7), urinary tract infections (7), obstructive voiding symptoms (5), and gross hematuria (3). Eleven cases were managed endoscopically, 4 using the holmium laser. One patient required subsequent cystorrhaphy. Four patients were managed with urethroplasty, 4 with cystorrhaphy, and the remainder utilizing a combination of techniques. No patients required complex reconstruction with interposition flaps. CONCLUSIONS: The diagnosis of iatrogenic foreign bodies in the lower urinary tract requires a high index of suspicion and a low threshold for performing cystoscopy. From this series, we have found that sutures can most often be managed successfully with endoscopic techniques, whereas mesh is best managed with cystorrhaphy and/or urethroplasty. To our knowledge, our series represents the largest number of reported iatrogenic foreign body removals at a single institution.

    Title Results of Cystocele Repair: a Comparison of Traditional Anterior Colporrhaphy, Polypropylene Mesh and Porcine Dermis.
    Date July 2007
    Journal The Journal of Urology
    Excerpt

    PURPOSE: Because traditional anterior colporrhaphy can have a high recurrence rate, we assessed the recurrence rate of 3 methods of cystocele repair, including 1) traditional anterior colporrhaphy, 2) repair using porcine dermis interposition graft and 3) repair using polypropylene mesh. Additionally, we compared the rate of erosion of porcine dermal graft with that of polypropylene mesh. MATERIALS AND METHODS: The records of patients who underwent cystocele repair by the same urologist using porcine dermal graft, polypropylene mesh or traditional repair from January 1999 to August 2005 were reviewed. Data were collected on history, physical examination, outcomes and complications. Using the Baden-Walker system a cystocele of grade 2 or higher on followup examination was considered recurrence. RESULTS: A total of 119 patients underwent cystocele repair from January 1999 to August 2005. Followup was available on 99 patients and it averaged 13.5 months (range 2 to 46). Of the patients 56 (57%) underwent cystocele repair using porcine dermal graft, 25 (25%) received polypropylene mesh and 18 (18%) underwent traditional repair. Of the 99 patients 22 (22%) had cystocele recurrence. Based on the type of repair 36% of patients (20 of 56) with porcine dermal grafts had recurrence compared to 4% (1 of 25) and 6% (1 of 18) using polypropylene and traditional repair, respectively. Mean time to cystocele recurrence was 4.9 months (range 0.5 to 20). A total of 12 patients (21%) had extrusion of porcine grafts through the anterior vaginal wall incision compared to 1 (4%) with polypropylene mesh. CONCLUSIONS: In our patient population the short-term failure rate for anterior vaginal wall prolapse using porcine dermis interposition graft was higher than that for traditional anterior colporrhaphy or polypropylene mesh. In addition, the incidence of vaginal extrusion of porcine graft was unacceptably high. Porcine dermis is a less suitable material for cystocele repair than polypropylene mesh or traditional anterior colporrhaphy. Prospective, randomized trials are necessary to determine the true efficacy and complication rates of these graft materials for anterior vaginal wall prolapse repair.

    Title Results of a Simplified Technique for Buried Penis Repair.
    Date February 2004
    Journal The Journal of Urology
    Excerpt

    PURPOSE: The buried penis can cause secondary phimosis, recurrent balanitis and social embarrassment. We report our results using a simplified technique for repair. MATERIALS AND METHODS: A retrospective chart review of 83 consecutive patients undergoing buried penis repair between March 1995 and March 2001 was performed. Indications for surgery included recurrent balanitis, secondary phimosis, difficulty holding the penis during voiding, spraying of the urinary stream, or parental or patient concern for social embarrassment. The technique involves fixation of the subcutaneous penile skin at the base of the degloved penis to Buck's fascia of the penile shaft at the 3 and 9 o'clock positions. RESULTS: For the 79 patients included in the study average followup was 4.4 years. Group 1 consisted of 26 patients who underwent circumcision at the time of buried penis repair. Six patients had hypospadias and 13 had penoscrotal webbing that was repaired simultaneously. Three patients (11.5%) had recurrent buried penis that required a repeat procedure and 1 (3.8%) required revision of the circumcision only. Three patients (11.5%) with penoscrotal webbing had mild recurrence requiring no further treatment. Group 2 consisted of 49 patients who underwent revision of the circumcision at the time of buried penis repair. Seven patients (14.3%) had mild recurrence that did not require further treatment. Group 3 consisted of 4 patients who underwent liposuction at the time of buried penis repair. One patient experienced lymphedema of the ventral distal shaft skin, which required subsequent excision. CONCLUSIONS: The buried penis repair is a simple and effective outpatient procedure with few complications and recurrences. It can be used as a primary or secondary procedure and affords good cosmetic results.
