Iatrogenic effects of radical cancer surgery on male fertility.

Iatrogenic causes of male infertility can include medications, chemotherapy, radiation, and surgery. In this review, we discuss commonly performed urologic cancer surgeries and nonurologic surgeries that harbor a high risk of iatrogenic infertility. These include radical prostatectomy, radical cystectomy, retroperitoneal lymph node dissection, pelvic colon surgery, and anterior spine surgery. In addition, we review the anatomy and surgical strategies that help to reduce the risks of infertility. With an increase in life expectancy and improvements in fertility preservation, it is important to properly counsel patients about the risks of infertility and provide options for fertility preservation before surgery.

A retrospective longitudinal evaluation of new overactive bladder patients in an FPMRS urologist practice: Are patients following up and utilizing third-line therapies?

AIMS: Third-line therapies are efficacious in improving overactive bladder (OAB) symptoms; however, OAB patients have poor follow-up and rarely progress to these therapies. Clinical care pathways (CCP) may improve OAB follow-up rates and third-line therapy use. We sought to determine how new OAB patients follow up and utilize third-line therapies with the implementation of an OAB CCP in a fellowship Female Pelvic Medicine and Reconstructive Surgery (FPMRS) trained urologist's academic practice. METHODS: We identified new OAB patients using ICD-9 and 10 codes. They were placed into two groups: pre- and post-CCP use. Basic demographic data were collected. Patients were evaluated in a retrospective longitudinal fashion over 12 months to determine follow-up and third-line therapy utilization. RESULTS: A total of 769 new OAB patients (261 pre-CCP and 508 post-CCP) were identified. The mean number of follow-up visits increased significantly at 6 months (0.94 vs. 1.64 visits, p = .001) and 12 months (1.26 vs. 2.46 visits, p < .003). Follow-up rates increased significantly at 3 months (38.7% vs. 50.2%, p = .002). Mean time to third-line therapy decreased significantly (280 days vs. 160 days, p = .016). Third-line therapy utilization therapy rates increased at 6 months (7.7% vs. 13.4%, p = .018) and at 12 months (11.1% vs. 16.5%, p = .044). CONCLUSIONS: New OAB patients follow-up and progress to third-line therapies faster and more frequently with the use of a CCP in an FPMRS-trained urologist practice. However, many OAB patients still fail to follow up and overall utilization of third-line therapies remains low. Future studies are warranted to identify factors to why overall OAB compliance remains low.

Clinical implications of telemedicine for providers and patients.

The coronavirus disease 2019 (COVID-19) pandemic has resulted in paradigm shifts in the delivery of health care. Lockdowns, quarantines, and local mandates forced many physician practices around the United States to move to remote patient visits and adoption of telemedicine. This has several long-term implications in the future practice of medicine. In this review we outline different models of integrating telemedicine into both male and female fertility practices and recommendations on performing video physical examinations. Moving forward we foresee two general models of integration: one conservative, where initial intake and follow-up is performed remotely, and a second model where most visits are performed via video and patients are only seen preoperatively if necessary. We also discuss the impact THAT telemedicine has on coding and billing and our experience with patient satisfaction.

Hypogonadism and metabolic syndrome: review and update.

PURPOSE OF REVIEW: The prevalence of metabolic syndrome and hypogonadism continues to rise in the United States and around the world. These two conditions are inexorably linked, and understanding their relationship with each other is key to treating men with either of these conditions. RECENT FINDINGS: Testosterone has been shown to be a key regulator in the maintenance of metabolic homeostasis. A large volume of research has found that testosterone deficiency is closely linked to metabolic syndrome through complex physiologic mechanisms of endothelial dysfunction, inflammation, and glucose metabolism. SUMMARY: Interventions through lifestyle modification and testosterone replacement in hypogonadal men may reduce the morbidity and mortality risks associated with metabolic syndrome.

Medicaid Patients Experience Longer Wait Times at Academic Urology Clinics Compared to Patients with Medicare.

INTRODUCTION: It has been established that Medicaid patients face unequal access to health care. There is a paucity of literature comparing wait times for Medicaid patients to those of patients with other types of insurance. We determined whether Medicaid patients experience longer wait times at academic urology clinics compared to patients with Medicare. METHODS: A prospective cross-sectional telephone survey was conducted in October 2016. The study involved collection of data from multiple academic centers with telephone interviews conducted from a single institution. Calls were made to all accredited urology residency programs (131). Earliest appointment times were established for fictional patients with Medicaid and then Medicare. The main outcome was the difference in wait times for a new patient appointment in a urology clinic for Medicaid vs Medicare patients. The wait time in days was the difference between the date of the appointment and the date of the telephone call. RESULTS: There were 108 academic urology clinics that accepted Medicaid and Medicare patients in our final analysis (82.4% participation rate). A 2-tailed t-test was performed with unequal variances for the wait times between Medicaid and Medicare groups. There was a significant difference (p <0.001) between mean wait times for a patient with Medicare (23 days, SD 20.8; 95% CI 19.0, 26.9) vs Medicaid (35 days, SD 27.5; 95% CI 30.0, 40.3). CONCLUSIONS: Our data suggest that Medicaid patients experience longer wait times for their initial outpatient urological evaluation. These findings may be used for future health policy considerations.

Complications of Renal Surgery.

The incidence of the small renal mass continues to increase owing to the aging population and the ubiquity imaging. Most of these tumors are stage I tumors. Management strategies include surveillance, ablation, and extirpation. There is a wide body of literature favoring nephron-sparing approaches. Although nephron-sparing surgery may yield decreased long-term morbidity, it is not without its drawbacks, including a higher rate of complications. Urologists must be attuned to the complications of surgery and develop strategies to minimize risk. This article reviews expected complications of surgery on renal masses and risk stratification schema.

Delay from biopsy to radical prostatectomy influences the rate of adverse pathologic outcomes.

BACKGROUND: We sought to determine maximum wait times between biopsy diagnosis and surgery for localized prostate cancer, beyond which the rate of adverse pathologic outcomes is increased. METHODS: We retrospectively reviewed 4,610 patients undergoing radical prostatectomy between 1990 and 2011. Patients were stratified by biopsy Gleason score and PSA value. For each stratification, χ2 analysis was used to determine the smallest 15-day multiple of surgical delay (e.g., 15, 30, 45…180 days) for which adverse pathologic outcomes were significantly more likely after the time interval than before. Adverse outcomes were defined as positive surgical margins, upgrading from biopsy, upstaging, seminal vesicle invasion, or positive lymph nodes. RESULTS: Two thousand two hundred twelve patients met inclusion criteria. Median delay was 64 days (mean 76, SD 47). One thousand six hundred seventy-five (75.7%), 537 (24.3%), and 60 (2.7%) patients had delays of <=90, >90, and >180 days, respectively. Twenty-six percent were upgraded on final pathology and 23% were upstaged. The positive surgical margin rate was 24.2% and the positive lymph node rate was 1.1%. Significant increases in the proportion of adverse pathological outcomes were found beyond 75 days in the overall cohort (P = 0.03), 150 days for patients with Gleason <=6, and PSA 0-10 (P = 0.038), 60 days for patients with Gleason 7 and PSA >20 (P = 0.032), and 30 days for patients with Gleason 8-10 and PSA 11-20 (0.041). CONCLUSION: In low-risk disease, there is a considerable but not unlimited surgical delay which will not adversely impact the rate of adverse pathologic features found. In higher risk disease, this time period is considerably shorter.

Baseline serum 25-hydroxyvitamin d levels in men undergoing radical prostatectomy: is there an association with adverse pathologic features?

INTRODUCTION/BACKGROUND: The purpose of this study was to evaluate the prevalence of vitamin D (VitD) deficiency in men undergoing radical prostatectomy and determine whether an association exists between preoperative VitD levels and adverse pathologic features. PATIENTS AND METHODS: Patients scheduled to undergo radical prostatectomy for clinically localized disease from January to August 2012 were prospectively followed and those with available preoperative serum 25-hydroxyvitamin D levels were included. Men with a known diagnosis of VitD deficiency or taking VitD supplementation were excluded. Cox regression analysis was performed to determine whether preoperative VitD level is predictive of adverse pathologic outcomes. RESULTS: One hundred consecutive men were included. Mean age was 62 (range, 42-79) years and mean VitD level was 26 (range, 6-57) ng/mL. Overall, 65 men (65%) had suboptimal levels of VitD (< 30 ng/mL), and 32 (32%) had deficiency (< 20 ng/mL). There was no significant correlation between VitD and age (P = .5). In logistic regression analysis, VitD level was not predictive of pathologic Gleason (P = .11), pathologic stage (P = .7), or positive margin status (P = .8). CONCLUSION: The association between VitD and prostate cancer has been controversial and data suggesting an increased risk of aggressive cancer in men with low levels of VitD have been inconsistent. We found that baseline preoperative VitD level was not associated with any adverse pathologic features. However, VitD deficiency is a common finding in this population, although unrelated to patient age. These results represent the first time the correlation between VitD and prostate cancer has been evaluated in a cohort of men undergoing radical prostatectomy.

Preliminary Evaluation of the endogo® HD Portable Cystoscopic Camera.

INTRODUCTION: During office cystoscopy and hospital consultations urologists may only have direct visualization cystoscopy available. Field of view and usability are often characterized as suboptimal compared to video tower based camera models. The endogo® HD, a portable, battery powered cystoscopic camera that attaches to a standard cystoscope, was created to more closely mimic the usability of the normal cystoscopic camera that connects to the video tower. We objectively evaluated the usefulness of this new device. METHODS: A total of 30 urology fellows, residents and students were consented and randomized to perform standard video tower cystoscopy, direct cystoscopy without a camera and cystoscopy with the endogo HD on a previously used Uro-Scopic Trainer bladder model (Limbs & Things USA, Savannah, Georgia). Participants were timed and evaluated using the previously validated OSATS (Objective Structured Assessment of Technical Skills). Each participant then rated the usability of and preferences for each of the 3 systems. All participants completed the 3 types of cystoscopy. RESULTS: Users found the field of view to be significantly better for the endogo HD than for direct cystoscopy (p = 0.03) and similar for the endogo HD and the tower (p = 0.7). Time needed to perform cystoscopy was significantly longer for endogo HD than for tower and direct cystoscopy (71.9 vs 43.3 and 46.8 seconds, respectively, p = 0.01). When comparing novices to experts (greater than 200 cases), experts completed all procedures more quickly regardless of camera type. Tower cystoscopy was significantly less difficult and more comfortable, and it was preferred by most participants. CONCLUSIONS: On objective and subjective measures the endogo HD portable cystoscopic camera received marks similar to those of other types of cystoscopy that are currently widely available. It required an average of a half minute longer to set up and overall participants preferred standard video tower cystoscopy. The endogo HD may be useful in the emergency department or office setting where no video tower is available. Further study of its usefulness as a teaching tool and the learning curve associated with its use will be performed in the future.

A Pilot Study of Laparoscopic Doppler Ultrasound Probe to Map Arterial Vascular Flow within the Neurovascular Bundle during Robot-Assisted Radical Prostatectomy.

Purpose. To report on the feasibility of a new Laparoscopic Doppler ultrasound (LDU) technology to aid in identifying and preserving arterial blood flow within the neurovascular bundle (NVB) during robotic prostatectomy (RARP). Materials and Methods. Nine patients with normal preoperative potency and scheduled for a bilateral nerve-sparing procedure were prospectively enrolled. LDU was used to measure arterial flow at 6 anatomic locations alongside the prostate, and signal intensity was evaluated by 4 independent reviewers. Measurements were made before and after NVB dissection. Modifications in nerve-sparing procedure due to LDU use were recorded. Postoperative erectile function was assessed. Fleiss Kappa statistic was used to evaluate inter-rater agreement for each of the 12 measurements. Results. Analysis of Doppler signal intensity showed maintenance of flow in 80% of points assessed, a decrease in 16%, and an increase in 4%. Plane of NVB dissection was altered in 5 patients (56%) on the left and in 4 patients (44%) on the right. There was good inter-rater reliability for the 4 reviewers. Use of the probe did not significantly increase operative time or result in any complications. Seven (78%) patients had recovery of erections at time of the 8-month follow-up visit. Conclusions. LDU is a safe, easy to use, and effective method to identify local vasculature and anatomic landmarks during RARP, and can potentially be used to achieve greater nerve preservation.

'Trifecta' after radical prostatectomy: is there a standard definition?

OBJECTIVES: To determine the extent of variability in the definitions of the 'trifecta' after radical prostatectomy (undetectable PSA, urinary continence and potency) to be found in the literature. To establish a consensus definition of the trifecta in an effort to standardize criteria and reporting. MATERIALS AND METHODS: A systematic review of published articles found in the PubMed database for the period from January 2003 to March 2012 was performed. The search queries included the keywords 'radical prostatectomy,' 'prostatectomy outcome,' and 'trifecta'. RESULTS: A total of 86 publications were identified of which 14 were used for analysis. Eight different definitions of biochemical recurrence were reported, the most common definition being PSA ≥0.2 ng/mL. The definition of potency was the most variable. Ten different definitions of potency were found, with the most common being 'having erections sufficient for intercourse with or without a phosphodiesterase-5 inhibitor'. Nine different definitions of continence were found. The most common definition of continence was 'wearing no pads'. Only six of the 14 articles used validated questionnaires in their outcome measures. CONCLUSIONS: The definitions of trifecta reported in the literature are highly variable. We propose the following consensus definition based on our analysis: (1) PSA >0.2 ng/mL with confirmatory value; (2) attainment of erections sufficient for intercourse with or without oral pharmacological agents; (3) wearing zero pads. This consensus definition should be considered when designing studies and reporting outcomes of radical prostatectomy.

Findings of routine apical margin biopsy during robot-assisted radical prostatectomy.

INTRODUCTION: Intraoperative biopsy of the apical margin during radical prostatectomy has been recommended as a way to reduce the positive margin rate at this location. However, the enhanced visibility of the apex during robot-assisted radical prostatectomy (RARP) may obviate this need, allowing for the preservation of maximal urethral length. We assessed pathologic findings of routine apical margin biopsy intraoperative frozen section (IFS) during RARP. PATIENTS AND METHODS: The Columbia University Robotic Database was retrospectively reviewed to identify men who underwent RARP with biopsy of the apical soft tissue (urethroprostatic junction). Both IFS and permanent section samples were analyzed. The clinical characteristics associated with IFS and permanent section histological findings were assessed. RESULTS: In total, 335 men underwent RARP with apical biopsy from December 2007 to August 2011. Of these, 329 had IFS available for analysis. Median age and prostate-specific antigen level were 60 years (range, 42-78 years) and 5.2 ng/mL (interquartile range, 4.1-6.9 ng/mL), respectively. Of the 329 apical IFS cases, cancer was detected in 9 patients (2.7%), benign prostatic glands in 135 (41%), and nonprostatic tissue in 185 (56.3%). On permanent section, cancer was seen in 9 patients (2.7%), benign prostatic glands in 125 (38%), and nonprostatic tissue in 195 (59.3%). False-positive and false-negative rates of detecting cancer on IFS were 33% (3/9) and 1% (3/320), respectively. The overall positive surgical margin rate was 11%. CONCLUSIONS: Cancer is rarely detected by IFS analysis of routine biopsy of the apical margin during RARP. Although routine IFS may not be beneficial for all patients, selective utilization of IFS may be useful in directing apical dissection in men with apical tumors, allowing for the preservation of maximal urethral length.

Does hospital setting post robotic fellowship training affect outcomes? A multi-institutional comparison of initial outcomes between academic and community settings.

The effect of practice setting on skill development post robotic fellowship training is currently unknown. We sought to compare learning curves between a high-volume academic center and a similar volume community hospital, in the setting of building a new robotic prostatectomy program. In addition, we sought to characterize benchmarks for learning curve development for post-fellowship training in robotic surgery. At two institutions, one academic (AC) and the other in the community (CO), the first 150 patients who underwent robotic laparoscopic prostatectomy over a period of 1 year were evaluated. We compared the following outcomes, operative time (OT), estimated blood loss (EBL), and positive surgical margin (PSM) rates, by two surgeons. Both surgeons completed the same surgical robotic fellowship in the same year. Cases were divided by tertile and primary outcomes measures were compared. Demographic data were similar between the two groups. Statistical differences were seen in age, preoperative Sexual Health Inventory for Men score, clinical and pathologic stage, and bladder neck reconstruction rate (p < 0.05). Overall, there was no significant difference in OT between AC (174 min) and CO (181 min) (p = 0.1099). Both EBL and PSM were lower in the AC (155 vs. 197 ml, p < 0.001 and 10 vs. 26 %, p < 0.05). The difference in OT was significant only in the first tertile of cases (AC 168 min vs. CO 193 min, p = 0.002). However, OT increased by 13 min in AC and decreased by 22 min in CO, when comparing the first and last tertile. EBL was different between AC (161ml) and CO (212 ml) only in the first tertile of cases (p = 0.002). Both AC and CO had increased EBL over the last tertile of cases (16.2 vs. 26.5 ml, respectively). These results demonstrate minor differences in outcomes between the two practice settings. Fellowship training in robotic surgery demonstrates a shorter learning curve towards achieving proficiency. Larger and longer term series will be required to assess functional outcomes and time to proficiency.

The first assistant sparing technique robot-assisted partial nephrectomy decreases warm ischemia time while maintaining good perioperative outcomes.

BACKGROUND AND PURPOSE: Prolonged warm ischemia time (WIT) and operative time (OT) during robot-assisted partial nephrectomy (RAPN) can adversely affect renal function and clinical outcomes. Minimizing the duration of WIT and OT is critical to achieving good results postoperatively. Our standard technique for RAPN has evolved into an intracorporeal preparation (ICP) that minimizes the reliance on the first assistant. The goal of the current study was to analyze outcomes after ICP RAPN compared with those of the standard RAPN. PATIENTS AND METHODS: A retrospective review of all patients who underwent RAPN was performed, comparing standard vs ICP technique. The ICP approach involves tacking of preprepared sutures along the abdominal sidewall adjacent to the kidney in preparation for hemostasis and renorrhaphy before arterial clamping, the use of robotic Scanlan(®) Reliance, bulldog clamps preplaced near the hilum of the kidney, and "sliding-clip" renorrhaphy. We compared intraoperative (OT, WIT, estimated blood loss [EBL]) and pre/postoperative outcomes (serum creatinine, glomerular filtration rate [GFR], length of stay [LOS]) of RAPN between the ICP and standard approach. RESULTS: A total of 44 consecutive RAPNs (18 ICP, 26 standard) were performed. Median nephrometry score was 7a, and mean follow-up was 13 months. Mean tumor size was 2.4 cm, and most common stage was T(1a). There was no significant difference between ICP and standard RAPN with regard to nephrometry score and stage. Mean WIT was significantly lower for the ICP vs standard RAPN (19 vs 23 min, P=0.049) as was mean OT (161 vs 204 min, P=0.027). On multivariate analysis, ICP RAPN was an independent predictor of WIT (P=0.02). There was no significant impact on preoperative and postoperative GFR for either approach. EBL and LOS were similar between the two groups. CONCLUSIONS: The ICP RAPN leads to a significant reduction in WIT and OT while maintaining similar perioperative outcomes compared with the standard approach.

Wounds measured from digital photographs using photodigital planimetry software: validation and rater reliability.

UNLABELLED:  Traditional wound tracing technique consists of tracing the perimeter of the wound on clear acetate with a fine-tip marker, then placing the tracing on graph paper and counting the grids to calculate the surface area. Standard wound measurement technique for calcu- lating wound surface area (wound tracing) was compared to a new wound measurement method using digital photo-planimetry software ([DPPS], PictZar® Digital Planimetry). METHODS: Two hundred wounds of varying etiologies were measured and traced by experienced exam- iners (raters). Simultaneously, digital photographs were also taken of each wound. The digital photographs were downloaded onto a PC, and using DPPS software, the wounds were measured and traced by the same examiners. Accuracy, intra- and interrater reliability of wound measurements obtained from tracings and from DPPS were studied and compared. Both accuracy and rater variability were directly related to wound size when wounds were measured and traced in the tradi- tional manner. RESULTS: In small (< 4 cm2), regularly shaped (round or oval) wounds, both accuracy and rater reliability was 98% and 95%, respectively. However, in larger, irregularly shaped wounds or wounds with epithelial islands, DPPS was more accurate than traditional mea- suring (3.9% vs. 16.2% [average error]). The mean inter-rater reliabil- ity score was 94% for DPPS and 84% for traditional measuring. The mean intrarater reliability score was 98.3% for DPPS and 89.3% for traditional measuring. In contrast to traditional measurements, DPPS may provide a more objective assessment since it can be done by a technician who is blinded to the treatment plan. Planimetry of digital photographs allows for a closer examination (zoom) of the wound and better visibility of advancing epithelium. CONCLUSION: Measurements of wounds performed on digital photographs using planimetry software were simple and convenient. It was more accurate, more objective, and resulted in better correlation within and between examiners. .
