Preliminary Outcomes of the Male Urethral "Mini-Sling": A Modified Approach to the Andrianne Mini-Jupette Procedure With Penile Prosthesis Placement for Climacturia and Mild Stress Urinary Incontinence.

INTRODUCTION: Previous worked showed that the Andrianne Mini-Jupette (AMJ) procedure with inflatable penile prosthesis (IPP) significantly improves climacturia or stress urinary incontinence (SUI) that may accompany erectile dysfunction (ED) after radical prostatectomy. However, with the AMJ procedure, the graft is incorporated into the medial aspect of the corporotomy, thereby requiring a more complex closure. Moreover, in the original report, multiple graft materials were used. AIM: To describe our technique for "male urethral mini-sling" (MUMS) with a Virtue sling mesh, which is a modified approach to the AMJ, and to assess early postoperative outcomes. METHODS: A retrospective chart review was performed for men who underwent IPP and MUMS placement with a modified Virtue mesh by 2 high-volume prosthetic urologic surgeons using the same technique. After proximal urethral exposure, the MUMS is sutured to the latera corpora over the bulbar urethra, proximal to and separate from the planned corporotomy, with care taken to avoid excessive urethral tension. The IPP is then placed in standard fashion. Changes in patient-reported climacturia and pads per day for SUI were assessed before and after surgery. RESULTS: 36 men underwent both IPP and MUMS placement between January 2016-October 2018. Mean patient age was 68 years. Etiology for ED and urinary symptoms was prostatectomy alone in 30 of 36 (83%) and prostatectomy plus radiation in 6 of 36 (17%). Preoperative urinary symptoms included climacturia in 30 of 36 (83%) and SUI in 27 of 36 (75%). Mean (SD) follow-up was 5.9 (3.7) months. Climacturia resolved in 28 of 30 (93%), and SUI improved in 23 of 27 (85%). The mean (SD) number of pads per day for those patients with SUI decreased significantly from 1.4 (1.1) before surgery to 0.4 (0.6) after surgery (P = .02). 1 patient required MUMS explantation for urethral erosion after prolonged postoperative catheterization. CLINICAL IMPLICATIONS: The MUMS with modified Virtue mesh at the time of IPP placement can be used to treat ED with climacturia or mild SUI after radical prostatectomy. STRENGTHS & LIMITATIONS: Strengths include the use of a consistent operative technique with a single graft material by 2 experienced prosthetic urologic surgeons. Limitations include the retrospective study design, use of subjective postoperative outcomes, lack of comparison group, and relatively moderate follow-up duration. CONCLUSIONS: Our early results suggest that the MUMS significantly improves bothersome climacturia and mild SUI in addition to treating ED, with little added morbidity. Although further study, including longer-term follow-up, is needed, this approach may be considered in the appropriately counseled patient. Valenzuela RJ, Ziegelmann MJ, Hillelsohn JH, et al.

Masked pneumothorax: risk of valveless trocar systems.

PURPOSE: Unlike traditional valved trocars, the valveless trocar maintains pneumoperitoneum during laparoscopy by forming a CO(2) curtain at the proximal end of the trocar. This gas barrier instantaneously maintains exact intraperitoneal pressure that yields to the transient physiological changes seen with breathing. Due to this different mechanism of action, pneumothorax development may be masked by the valveless trocar system. MATERIALS AND METHODS: We retrospectively reviewed 850 transperitoneal laparoscopic kidney and adrenal surgeries in which a valveless trocar system was used to determine any record of pneumothorax detected intraoperatively or postoperatively. A patient with pneumothorax was considered a case and anesthetic parameters were reviewed. A matched control group was generated from patients treated with transperitoneal laparoscopic kidney and adrenal surgery using the valveless trocar with no complications. RESULTS: Pneumothorax was diagnosed in 10 patients (1.2%). Two cases were the result of intentional excision of the diaphragm, which were repaired intraoperatively, while 8 were not recognized until the postoperative period. Five of the patients (63%) with unintentional pneumothorax required chest tube placement for a mean of 2.4 days. The remaining 3 patients (37%) were treated conservatively and followed with serial chest x-rays. The only anesthetic variable that was significantly different between the groups was Δ end tidal CO(2) with greater fluctuations in end tidal CO(2) in the pneumothorax group than in controls (p = 0.03). CONCLUSIONS: Pneumothorax is a rare complication of laparoscopic urological surgery that is usually recognized intraoperatively through physiological changes. Valveless trocar systems mask these findings and can delay identification until the postoperative period.

Pfannenstiel laparoendoscopic single-site (LESS) vs conventional multiport laparoscopic live donor nephrectomy: a prospective randomized controlled trial.

OBJECTIVE: To present outcomes of a randomized, patient-blinded controlled trial on Pfannenstiel laparoendoscopic single-site (LESS) vs conventional multiport laparoscopic live donor nephrectomy. PATIENTS AND METHODS: Patients presenting as left kidney donors between January 2009 and November 2011 were randomized to LESS donor nephrectomy (LESS-DN: n = 15) or conventional laparoscopic donor nephrectomy (LDN: n = 14). Patients were blinded to the surgical approach preoperatively and attempts to continue patient blinding postoperatively were made by applying dressings consistent with multiple conventional laparoscopic incisions for all patients. De-identified data related to the operation, peri-operative course and postoperative follow-up were prospectively collected and compared between the two groups with an intention-to-treat analysis. RESULTS: There were no significant differences between the groups when comparing operating time, estimated blood loss (EBL), i.v. fluid administration, renal allograft warm ischaemia time (WIT), length of hospital stay (LOS) and total inpatient analgesic requirements. Quantitative pain assessment was not significantly different on postoperative day (POD) #0, however, it was significantly lower in the LESS-DN group, beginning on POD #1 (P < 0.05). The changes in haematocrit and serum creatinine in the two groups were not significantly different, and there were no blood transfusions in either group, nor was there a decline in estimated glomerular filtration rate to <60 mL/min per 1.73 m² of body surface area in any patients. Two patients in the LESS-DN group were converted to conventional LDN, both because of failure to progress effectively. All allografts were functional at the time of transplantation and revascularization, with no cases of hyperacute rejection. CONCLUSIONS: Peri-operative variables including EBL, WIT and LOS were equivalent when comparing Pfannenstiel LESS-DN with conventional LDN. Patient-reported visual analogue pain scale scores were significantly lower in the LESS-DN group beginning on the first postoperative day.

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 0.6 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 × 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.

Fulguration for Hunner ulcers: long-term clinical outcomes.

PURPOSE: Cystoscopic fulguration of Hunner ulcers in patients with interstitial cystitis/bladder pain syndrome is a recommended therapy because it has the potential to rapidly ameliorate symptoms. We reviewed our experience with Hunner ulcer fulguration. MATERIALS AND METHODS: We retrospectively reviewed the records of patients with interstitial cystitis/bladder pain syndrome treated with Hunner ulcer fulguration who were seen at our pelvic pain referral center between 1993 and 2011. Patient demographics, clinical characteristics, intraoperative findings and long-term clinical outcomes were assessed. The Kaplan-Meier product limit method was used to evaluate time to the first repeat procedure. Potential risk factors associated with repeat procedures were examined using the log rank test. RESULTS: A total of 106 procedures were performed in 59 patients. The mean history of illness before first fulguration was 5 years and overall median followup was 44.8 months (IQR 52.2), as calculated from the time of the first fulguration. There were no significant associations between time to the first repeat procedure and any demographic criteria analyzed, patient reported interstitial cystitis/bladder pain syndrome associated conditions or the number of Hunner ulcers fulgurated at the initial session. A total of 27 patients (45.8%) required repeat fulguration. Time to event analysis demonstrated that 12 months after the initial fulguration 13.1% of patients required repeat treatment. This rate increased to 57.2% at 48 months, when it plateaued. CONCLUSIONS: Fulguration of Hunner ulcers can be an effective treatment for patients with interstitial cystitis/bladder pain syndrome and focal Hunner ulcers involving less than 25% of the bladder who have symptoms refractory to other therapies. However, a significant subset requires repeat treatment and some patients may even go on to require cystectomy.

Variability of transrectal ultrasound-guided prostate biopsy prophylactic measures.

INTRODUCTION: To assess the variability of pre-prostate biopsy prophylaxis among American urologists. MATERIALS AND METHODS: A survey was electronically mailed to 3355 urologists around the country. Urologists were surveyed on their antibiotic prophylaxis choice, the route and duration of antimicrobial prophylaxis. Additionally they were questioned about their knowledge of local antimicrobial resistance and if rectal enemas were routinely used. RESULTS: There were 679 (21%) responses to the survey. The survey revealed differences in pre-prostate biopsy prophylaxis among urologists. Ten different classes of antibiotics were used orally, 4 classes intramuscular, 5 classes intravenous, and there was also 14 different duration regimens. CONCLUSION: Despite the initiation of the 2008 American Urological Association Guidelines on this topic, there still is a lack of uniformity in prostate biopsy prophylaxis.

The differential pupillary response to 2.5% phenylephrine in patients taking tamsulosin.

PURPOSE: To determine if a pharmacological test could be developed to determine iris dilator dysfunction in patients taking tamsulosin. METHODS: Patients taking tamsulosin and controls were recruited from the Urology and Ophthalmology clinics at the Montefiore Medical Center. The patient's right eye (OD) was dilated with phenylephrine hydrochloride 2.5% and tropicamide 1%. The patient's left eye (OS) was dilated with tropicamide 1% alone. Forty minutes after dilation, pupillary diameter was measured in both eyes. RESULTS: Thirty-eight tamsulosin subjects and 43 controls met the inclusion criteria for the study. The tamsulosin-treated patients dilated less with phenylephrine than controls (0.61±0.4 vs. 1.10±0.45 mm, respectively P<0.001). Receiver operating characteristic curves comparing maximal pupillary dilation versus differential pupillary dilation in tamsulosin patients relative to controls shows a greater area under the curve for differential dilation (0.8 vs. 0.6, respectively). A correlation between smooth muscle dysfunction and length of time on tamsulosin was observed. Patients using tamsulosin for <1 month had an average OD-OS difference of 0.85±0.5 mm. Patients who were on tamsulosin for >1 month had an average OD-OS difference of 0.52±0.32 mm (P<0.01, Mann-Whitney). CONCLUSION: Patients treated with tamsulosin demonstrated a significantly decreased iris dilatory response to the selective adrenergic effects of phenylephrine compared to controls. Additionally, it appears that longer duration of exposure to tamsulosin increases the likelihood of dilator dysfunction.

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.

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 <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.

Laparoscopic retroperitoneal lymph node dissection for testicular cancer.

OBJECTIVES: Laparoscopic retroperitoneal lymph node dissection (L-RPLND) was introduced over 20 years ago as a less invasive alternative to open node dissection. In this review we summarise the indications, surgical technique and outcomes of L-RPLND in the treatment of testicular cancer. METHODS: We searched MEDLINE using the terms 'laparoscopy', 'laparoscopic', 'retroperitoneal lymph node dissection', 'RPLND' and 'testicular neoplasms'. Articles were selected on the basis of their relevance, study design and content, with an emphasis on more recent data. RESULTS: We found 14 pertinent studies, which included >1300 patients who received either L-RPLND (515) or open RPLND (788). L-RPLND was associated with longer mean operative times (204 vs. 186 min), but shorter hospital stays (3.3 vs. 6.6 days) and lower complication rates (15.6% vs. 33%). Oncological outcomes were similar between L-RPLND and open RPLND, with local relapse rates of 1.3% and 1.4%, incidence of distal progression of 3.3% and 6.1%, biochemical failure in 0.9% and 1.1% and cure rates of 100% and 99.6%, respectively. CONCLUSION: There are no randomised controlled studies comparing L-RPLND with open RPLND. A review of case and comparative series showed similar perioperative and oncological outcomes. Patients undergoing L-RPLND on average have shorter hospital stays, a quicker return to normal activity and improved cosmesis.
