ABSTRACT

Prosthetic urology can substantially enhance the quality of life for patients. However, it is not without challenges. Infections of penile prostheses and artificial urinary sphincters are often difficult to diagnose, manage, and treat. Over time, device improvements, refined surgical methods, better understanding of microbiology, and biofilms in combination with higher sterility standards and protocols, have significantly reduced the rates of infection. Here, the authors offer a comprehensive overview of prosthetic urologic infections and their management in the current era.

ABSTRACT

OBJECTIVE: To evaluate the contribution of the standardized letter of recommendation (SLOR) to the likelihood of matching in urology residency by applying a novel scoring system and characterize utilization in the 2022 application cycle. METHODS: We conducted an investigation of all applicants to our urology residency program during the 2022 cycle. We developed a scoring system to assess SLOR strength across all templates. Match outcomes were verified with the Society of Academic Urologists listing. Statistical analysis was performed to assess for factors predictive of a successful match. RESULTS: Out of 386 total applicants, 239 (61.9%) had at least 1 SLOR in their application. SLOR utilization was more prevalent in MD applicants, in those with higher Step 2 scores, and in those who matched (P <.01). The majority of SLOR scores (66.5%) were above a 3.5/5 in our cohort. Step 1 score, number of research entries, and presence of an SLOR were predictive of successful match. However, a SLOR score of <3 was strongly associated with not matching (OR 0.021, P <.01). CONCLUSION: The presence of a SLOR in our cohort overall was associated with a successful match. A poor SLOR score was highly deleterious to an applicant's chance of matching in urology. Our SLOR scoring system can be used across all letter templates and demonstrates that strength of SLOR can significantly impact an applicant's chance of matching.

ABSTRACT

Treatment options for men with moderate-to-severe lower urinary tract symptoms (LUTS) due to benign prostatic hyperplasia (BPH) have variable efficacy, safety, and retreatment profiles, contributing to variations in patient quality of life and healthcare costs. This study examined the long-term cost-effectiveness of generic combination therapy (CT), prostatic urethral lift (PUL), water vapor thermal therapy (WVTT), photoselective vaporization of the prostate (PVP), and transurethral resection of the prostate (TURP) for the treatment of BPH. A systematic literature review was performed to identify clinical trials of CT, PUL, WVTT, PVP, and TURP that reported change in International Prostate Symptom Score (IPSS) for men with BPH and a prostate volume ≤80 cm3. A random-effects network meta-analysis was used to account for the differences in patient baseline clinical characteristics between trials. An Excel-based Markov model was developed with a cohort of males with a mean age of 63 and an average IPSS of 22 to assess the cost-effectiveness of these treatment options at 1 and 5 years from a US Medicare perspective. Procedural and adverse event (AE)-related costs were based on 2021 Medicare reimbursement rates. Total Medicare costs at 5 years were highest for PUL ($9,580), followed by generic CT ($8,223), TURP ($6,328), PVP ($6,152), and WVTT ($2,655). The total cost of PUL was driven by procedural ($7,258) and retreatment ($1,168) costs. At 5 years, CT and PUL were associated with fewer quality-adjusted life years (QALYs) than WVTT, PVP, and TURP. Compared to WVTT, the incremental cost-effectiveness ratios (ICERs) for both TURP and PVP were above a willingness-to-pay threshold of $50,000/QALY (TURP: $64,409/QALY; PVP: $87,483/QALY). This study provides long-term cost-effectiveness evidence for several common treatment options for men with BPH. WVTT is an effective and economically viable treatment in resource-constrained environments.

ABSTRACT

OBJECTIVE: To demonstrate the distribution and impact of fellowship-trained andrology and/or sexual medicine urological specialists (FTAUS) on resident in-service examination (ISE) performance. METHODS: Residency program websites were accessed to create a database of FTAUS in the United States between 2007 and 2017. This database was reviewed by three separate FTAUS and cross referenced with membership lists to the Sexual Medicine of North America Society and the Society for the Study of Male Reproduction. De-identified ISE scores were obtained from the American Urological Association from 2007-2017 and scores from trainees at programs with a FTAUS were identified for comparison. Resident performance was analyzed using a linear model of the effect of a resident being at a program with an FTAUS, adjusting for post-graduate year. RESULTS: ISE data from 13,757 residents were obtained for the years 2007-2017. The number of FTAUS in the United States increased from 40-102 during this study period. Mean raw scores on the "Sexual Dysfunction, Endocrinopathy, Fertility Problems" (SDEFP) section of the ISE ranged from 52.1% ± 17.7% to 65.7% ± 16% (mean ± SD). Throughout the study period, there was no difference in performance within the SDEFP section (P < .01). Residents at a program with a FTAUS answered 0.95% more questions correctly in the SDEFP than those without a FTAUS (P < .001). For these residents, there was an improvement of approximately 0.66% on the percentage of questions answered correctly on the ISE overall (P < .001). Performance improved significantly as residents progressed from PGY-2-PGY-5. CONCLUSION: There is a small but statistically significant improvement in overall ISE and SDEFP sub-section performance.

ABSTRACT

OBJECTIVE: To analyze national performance trends of urology residents on the American Urological Association In-Service Examination (ISE) over the last 18 years. METHODS: Trends in the national averages on the in-service examination for each year of residency training were collected and analyzed between the years 2000 and 2017. Mean and standard error were calculated for examination performance for each year of residency. Subject-specific performance was also determined for each given year of residency. Regression analysis was used to model trends in performance as a function of residency year. RESULTS: There was no significant difference in examination performance over 18 years with respect to each specific residency year. While there was an overall improvement in total scores with each advancing training year, year-over-year improvement in total examination performance began to plateau after Uro-2. Largest absolute performance improvement from Pre-Uro to Uro-4 were in subjects of "Urinary Diversion," "Obstructive Uropathy" and "Neoplasm." Scores in "Sexual Dysfunction, Endocrinopathy, Fertility Problems", and "Congenital Anomalies, Embryology, Anatomy" were consistently the lowest regardless of year of training. CONCLUSION: No significant change in performance was seen in each given year of residency over the 18-year period. There was improvement in overall scores as residents progressed through training, but scores plateaued after Uro-2 with minimal improvement between Uro-3 and Uro-4 years. Difference in subject scores suggests a disparity in educational focus in residency curricula and a potential need to improve the teaching strategies for subjects that tested less well throughout residency training.

ABSTRACT

Background: Historically, exocrine pancreas secretions during pancreas transplant were commonly managed by bladder drainage. Although this technique has fallen out of favor because of significant rates of urologic complications, urologists must still be prepared to assist when they arise. We describe the first reported case of a cystoscopically placed pancreatic duct stent for management of a pancreas transplant duodenocystostomy leak in the setting of normal bladder function. Case Presentation: A 63-year-old male with a history of type 1 diabetes mellitus complicated by end-stage renal disease underwent a simultaneous bladder-drained pancreas and kidney transplant 25 years ago. He developed hematuria and acute rejection of his pancreas, with CT showing large volume ascites concerning for pancreatic leak. Cystoscopy revealed an intact and patent duodenal-cystostomy anastomosis; however, intraperitoneal extravasation on intraoperative cystogram raised concern for pancreatic head necrosis. The patient underwent intraperitoneal drain placement and Foley catheter bladder decompression, but drain output and drain amylase and lipase remained markedly elevated. He was taken back to the operating room for attempted cystoscopic stenting of the pancreatic duct, which was effective using a 5F × 4 cm Zimmon® pancreatic stent. His drain output normalized in the following days and the pancreatic stent and intraperitoneal drain were removed 4 and 5 weeks after discharge, respectively. Outpatient urodynamics revealed no signs of obstruction and his catheter was removed with minimal postvoid residuals on follow-up. Conclusion: Anastomotic leak after duodenocystostomy during pancreas transplant is a complication typically related to elevated intravesical pressures, managed with bladder decompression and subsequent bladder outlet procedure. We present a novel technique for cystoscopic pancreatic duct stenting in the setting of intact anastomosis and normal bladder function with delayed leak secondary to necrotic pancreatic head. Endoscopic stent placement, intraperitoneal drainage, and bladder decompression with Foley catheter are an effective technique to avoid unnecessary reconstructive surgery.

ABSTRACT

INTRODUCTION: We determined the usefulness of ultrasound compared to cross-sectional imaging in the detection of intra-abdominal recurrences after radical or partial nephrectomy for localized renal cell carcinoma. METHODS: We performed a retrospective review of 800 patients with clinically localized renal cell carcinoma who had undergone radical or partial nephrectomy between 2008 and 2015. Patients had at minimum 1 year of followup at our institution, at least 1 ultrasound during surveillance and no metastases at time of surgery. Our primary outcome was the rate of diagnosis of abdominal recurrence based on modality of surveillance. RESULTS: Median followup for the entire cohort was 37.5 months (range 12 to 166). Overall 396 and 404 patients underwent radical and partial nephrectomy, respectively, for localized renal cell carcinoma. There were 224 (57%) and 234 (58%) patients in the radical and partial nephrectomy cohorts, respectively, who had 2 or more ultrasounds performed during surveillance. In the radical and partial nephrectomy cohorts a total of 149 (19%) abdominal recurrences were detected, with only 8 (19%) initially detected by ultrasound. On the other hand, 15 (10%) recurrences were missed by a prior negative ultrasound. Furthermore, there were 8 false-positive ultrasound studies that cross-sectional imaging later ruled out. CONCLUSIONS: The low yield of ultrasound in the detection of abdominal recurrences after radical or partial nephrectomy for renal cell carcinoma raises questions as to its usefulness in routine surveillance.

ABSTRACT

INTRODUCTION: We instituted a ketamine-predominant analgesic regimen in the peri- and postoperative periods to limit the effects of narcotic analgesia on bowel function in patients undergoing radical cystectomy. The primary end points of interest were time to return of bowel function, time to discharge, and efficacy of the analgesic regimen. METHODS: We performed a retrospective chart review of patients undergoing robotic-assisted laparoscopic cystectomy (RARC) with urinary diversion by a single surgeon at our institution from January 1, 2011 to June 30, 2012. Patients receiving the opioid-minimizing ketamine protocol were compared to a cohort of patients undergoing RARC with an opioid-predominant analgesic regimen. RESULTS: In total, 15 patients (Group A) were included in the ketamine-predominant regimen and 25 patients (Group B) in the opioid-predominant control group. Three patients (19%) in Group A discontinued the protocol due to ketamine side effects. The mean time to bowel movement and length of stay in Group A versus Group B was 3 versus 6 days (p < 0.001), and 4 versus 8 days, respectively (p < 0.001). Group A patients received an average of 13.0 mg of morphine versus 97.5 mg in Group B (p < 0.001). CONCLUSIONS: Patients who received our ketamine pain control regimen had a shorter time to return of bowel function and length of hospitalization after RARC. Our study has its limitations as a retrospective, single surgeon, single institution study and the non-randomization of patients. Notwithstanding these limitations, this study was not designed to show inferiority of one approach, but instead to show that our protocol is safe and efficacious, warranting further study in a prospective fashion.

ABSTRACT

The potency of pharmaceutical compounds acting on ion channels can be determined through measurements of ion channel conductance as a function of compound concentration. We have developed an artificial lipid bilayer chip for simple, fast, and high-yield measurement of ion channel conductance with simultaneous solution perfusion. Here we show the application of this chip to the measurement of the mammalian cold and menthol receptor TRPM8. Ensemble measurements of TRPM8 as a function of concentration of menthol and 2-aminoethoxydiphenyl borate (2-APB) enabled efficient determination of menthol's EC(50) (111.8 µM ± 2.4 µM) and 2-APB's IC(50) (4.9 µM ± 0.2 µM) in agreement with published values. This validation, coupled with the compatibility of this platform with automation and parallelization, indicates significant potential for large-scale pharmaceutical ion channel screening.
