Robotic-assisted laparoscopic bladder augmentation in the pediatric patient.

INTRODUCTION: Bladder augmentation is a common surgical intervention for neuropathic bladder dysfunction, and has conventionally been an open procedure. We present a robotic ileocystoplasty to demonstrate the feasibility of an entirely intracorporeal approach in a pediatric patient. METHODS: The patient was a 6 year old (18.5 kg) boy with a neurogenic bladder secondary to lumbar myelomeningocele. Urodynamics revealed a small capacity and poorly compliant bladder and he was incontinent between frequent catheterizations. A robotic augmentation cystoplasty was performed. RESULTS: At one-month postoperatively, a cystogram revealed no urine leak, and the suprapubic tube was removed. The patient resumed CIC every 3 h during the day and once overnight until postoperative urodynamic studies confirmed safe dynamics, after which the CIC interval was lengthened. CONCLUSION: Robotic bladder augmentation is safe and feasible in a select pediatric population. The entire procedure including preparation of the bowel segment can be completed intracorporeally, even in smaller children.

The effect of spinal cord level on sexual function in the spina bifida population.

INTRODUCTION: Sexual dysfunction and infertility are prevalent in the spina bifida (SB) population; however, the mechanism of how they affect a person with spina bifida is poorly understood. Additionally, the management of children with spina bifida becomes more difficult as they exit from pediatric institutes. OBJECTIVE: The present study sought to evaluate sexual health (using validated questionnaires) and fertility in adults with spina bifida and to correlate spinal cord level and ambulatory status with degree of sexual function. STUDY DESIGN: After institutional board review approval, 199 adult patients with SB, aged 18 and older and who were followed in one pediatric institution, were identified. Patients who were non-English speaking, cognitively and/or developmentally delayed, or unable to be contacted were excluded. Surveys regarding demographics, sexual health and infertility were mailed to the patients and administered in the clinic with the option to opt-out of the survey. Survey questions regarding sexual health were constructed using validated questionnaires: Female Sexual Function Index (FSFI) for females, and International Index of Erectile Function (IIEF) and Sexual Health Inventory for Men (SHIM) for males. Sexual dysfunction scores were correlated to the patients' spinal level and ambulatory status. RESULTS: Of the 121 eligible patients, 45 replied, with a response rate of 39%. For females, using a cut-off value of 26.5 for FSFI scoring, 25 out of 28 (89%) had sexual dysfunction. No association was seen between spinal level or ambulatory status and overall FSFI, satisfaction, or desire scores. For males, 10 out of 17 (59%) had severe erectile dysfunction (ED), and one out of 17 (6%) had no ED. No association was seen between ambulatory status and sexual function scores for the males. However, SHIM, satisfaction, and ED scores were higher in males with lower spinal lesions. People with spina bifida of both genders tended to have more severe dysfunction compared to those with sexual dysfunction of other etiologies, except with similar sexual desire scores. Regarding questions on fertility, no participant attempted to have children; thus, there was no infertility reported. DISCUSSION: Few studies have been conducted on sexual health and fertility in adults with SB. Three studies have utilized validated questionnaires and found varying degrees of sexual dysfunction in this subset of patients; however, only one study found sexual activity to be more likely in patients with more caudal levels of neurologic impairment. The present study also showed that SHIM, satisfaction, and ED scores were higher in males with lower spinal lesions. Limitations to this study primarily included the small sample size and low survey response rate. CONCLUSION: Limited information is known about adults with SB, and sexual function and fertility. While expressing sexual desire, adults with SB appear to experience high rates of sexual dysfunction. Fertility rates were inadequately assessed; this was possibly due to the high rate of sexual dysfunction. Sexual health in the SB population is an important component of the myriad of urologic care issues for these people. Due to the disparity in their care after reaching adulthood, it is prudent to follow these patients and understand their pathophysiology as they continue to mature through life.

Intralesional verapamil for the treatment of Peyronie's disease: a review.

Multiple treatment options have been used for Peyronie's disease (PD) including intralesional injection of the calcium antagonist verapamil. The use of verapamil is based on its capacity to alter fibroblast function at several levels, including cell proliferation, extracellular matrix protein synthesis and secretion, as well as collagen degradation. Consequently, calcium antagonists may have the capacity to slow, prevent, or even reverse plaque formation and the progression of PD. The multicenter international experience with intralesional verapamil injection suggests that the majority of men with PD that receive treatment demonstrate durable reduction in pain, decrease in curvature, and improved sexual function. We review the scientific rationale, published literature, clinical experience, and technique of intralesional injection of verapamil.

Mechanical reliability and safety of, and patient satisfaction with the Ambicor inflatable penile prosthesis: results of a 2 center study.

PURPOSE: We reviewed the experience with the 2-piece Ambicor penile prosthesis (American Medical Systems, Minnetonka, Minnesota) at 2 medical centers to investigate its mechanical reliability and complication rates as well as patient and partner satisfaction with the device. MATERIALS AND METHODS: From 1995 through 1999, 131 men underwent implantation of an Ambicor penile prosthesis at 2 medical centers. We performed a 3-part study consisting of a retrospective clinical record review, mailed patient and partner questionnaire, and mailed modified patient and partner Erectile Dysfunction Inventory of Treatment Satisfaction questionnaire. Mean followup was 43.4 months (range 12 to 73). RESULTS: All 131 men had a history consistent with an organic etiology of erectile dysfunction, including vascular disease in 62%, radical retropubic prostatectomy in 17%, Peyronie's disease in 15%, neophallus construction in 4% and radical pelvic surgery in 2%. Mean patient age was 56.8 years (range 22 to 76) at implantation. Overall there were complications in 10 cases (7.6%), including infection, hematoma and mechanical failure in 6 (4.6%), 1 (0.7%) and 3 (2.3%), respectively. A total of 112 men (85%) and 91 partners completed the questionnaire. All patient respondents still had an Ambicor prosthesis implanted and 96.4% had erection suitable for coitus. Overall patient and partner satisfaction was 96.4% and 91.2%, respectively. Of the respondents 92.9% of patients and 90.1% of partners would recommend the device to others. Of the 85 men (65%) and 46 partners who completed the modified Erectile Dysfunction Inventory of Treatment Satisfaction survey 90.6% and 82.6%, respectively, were satisfied or very satisfied overall with the penile prosthesis. CONCLUSIONS: The Ambicor penile prosthesis is associated with a low complication rate and reliable mechanical function. High satisfaction was reported by patients and partners.
