Use of Desipramine for the Treatment of Overactive Bladder Refractory to Antimuscarinic Therapy

Purpose: To evaluate the use of desipramine in the treatment of overactive bladder (OAB). Materials and Methods: We retrospectively evaluated 43 patients who were treated with desipramine for OAB refractory to antimuscarinic therapy. These OAB patients were stratified by the presence or absence of bladder pain. Results: Forty-three patients were evaluated with a mean follow up time of 12.2 +/- 4.6 months. The mean age of the patients was 71 16 years. Twelve patients (28%) discontinued desipramine, 9 due to perceived lack of efficacy, 2 due to central anticholinergic side effects, and 1 due to the development of oropharyngeal sores. Patients were stratified into two subgroups based upon treatment with desipramine for OAB alone (n = 29) or OAB and bladder pain (n = 14). There was no difference between the groups in regard to sex (P = .34), prior history of radiation (P = .19), side effects (P = .16), and specifically evaluated central anti-cholinergic side effects (P = .66). There was no statistical difference in the self-reported success rate of the medication (P = .48). In the OAB plus bladder pain subgroup, 71% of patients reported improvement in their pain. Overall, 13 (30%) patients had history of prior pelvic radiation and 10 of those (77%) reported improvement with desipramine. Conclusion: Desipramine is a potential useful treatment for patients with OAB. In addition, it can be used in patients with OAB and bladder pain and patients with complex OAB such as OAB caused by pelvic radiation

Spectral Doppler Sonography A Noninvasive Method for Predicting Dyspermia

Objectives-Sonography is a noninvasive, office-based diagnostic tool often used for evaluation of subfertile men. Previous studies have suggested that a resistive index (RI) greater than 06 is associated with impaired spermatogenesis. We sought to validate this threshold in a urologic patient population presenting for infertility evaluation. Methods-We retrospectively reviewed 99 consecutive patients seen for nonobstructive male infertility at our institution. Patient demographics, semen analysis parameters, hormone profiles, lipid profiles, and penile and scrotal sonographic measurements were recorded. The RI was calculated from measurements of the peak systolic velocity and end-diastolic velocity. Ninety-one patients fit the inclusion criteria and were subsequently divided into 2 groups based on RI: group 1 with RI values of 0.6 or less (n = 49) and group 2 with RI values greater than 0.6 (n = 42). Results-Variables that were significantly different between the groups included age, total sperm count, percent motile sperm, total motile sperm, follicle-stimulating hormone, high-density lipoprotein, and testis volume. On the other hand, body mass index, forward progression, World Health Organization score, total testosterone, free testosterone, estradiol, total cholesterol, low-density lipoprotein, and triglycerides were not significantly different between the groups. A receiver operating characteristic curve revealed an area under the curve of 0.64 (confidence interval, 0.52-0.75; P = .025). At the threshold of greater than 0.6, the RI had specificity of 63.27% and a 1.56 likelihood ratio to predict total motile sperm less than 20 x 10(6) at spermatogenesis. Conclusions-An intratesticular RI greater than 0.6 is associated with impaired spermatogenesis. This finding supports the use of testicular spectral Doppler sonography as a noninvasive tool for evaluation of testicular function

Contemporary perspectives on laparoendoscopic single-site surgery in urologic training and practice

Introduction: The initial surge of interest in laparoendoscopic single-site (LESS) surgery is balanced by skepticism regarding its future. We sought to evaluate the perspectives of practicing urologists on the role of LESS in urologic training and practice. Materials and Methods: An anonymous questionnaire was electronically mailed to members of the Endourological Society and the American Urological Association. Questions were grouped in three domains: training background and LESS experience, perspectives on LESS training, and perspectives on LESS in a current urologic practice. Results: Four hundred twenty-two surveys were completed. Respondents had a mean of 11.7 years in practice and 60.7% completed fellowship training. LESS was performed by 44.7% of respondents, however, of these respondents, 75% had only performed \u3c 10 LESS cases. For timing of LESS training, 50% believed LESS should be taught during residency and 39% during fellowship. Hands-on workshops and courses were thought to be insufficient by a majority (56%) for learning the LESS techniques before use in practice, and 51% support a credentialing process for urologists performing LESS surgery. Assessing the role of LESS in urologic practice, in its current state, LESS was deemed to provide superior cosmesis (69%) more commonly believed by those with LESS experience 77% versus 63% (p = 0.004), however, without yielding a quicker recovery (75%) or less postoperative pain (73%). Conclusion: LESS is viewed as an area with potential growth with benefits of superior cosmesis. LESS training should be more integrated into residency and fellowship training and establishing a credentialing process for LESS should be strongly considered by accrediting bodies

The surgical spectacle: a survey of urologists viewing live case demonstrations

OBJECTIVE: To evaluate perspectives of urologists viewing live case demonstrations (LCD) and taped case demonstrations (TCD). METHOD: A 15-question anonymous survey was distributed to attendees of the live surgery session at the American Urological Association 2012 national meeting (Atlanta) and the second International Challenges in Endourology meeting (Paris). RESULTS: Of 1000 surveys distributed, 253 were returned completed (response rate 25%). Nearly half of respondents were in the academic practice setting and nearly 75% were beyond training. Just over 30% had performed a LCD previously. The perceived benefit of an LCD was greater than unedited and edited videos (chi-squared P = 0.014 and P \u3c 0.001, respectively). Nearly no one selected \u27not helpful\u27 and a few selected \u27minimally helpful\u27 for any of the three forms of demonstration. Most respondents identified that opportunity to ask questions (61%) and having access to the full unedited version (72%), two features inherent to LCD, improved upon the educational benefit of edited videos. Most (78%) identified LCD as ethical. However, those that did not perceived lower educational benefit from LCD (P = 0.019). A slim majority (58%) would allow themselves or a family member to be a patient of a LCD and the vast majority (86%) plan to transfer knowledge gained at the LCD session into their practice. CONCLUSIONS: Urologists who attended these LCD sessions identified LCDs as beneficial and applicable to their practice. LCDs are preferred over videos. The large majority considers LCD ethical, although not as many would volunteer themselves for LCD. Further studies are necessary to determine if there is actual benefit from LCD over TCD to patient care
