Background and Purpose: Laparoscopic and especially robot-assisted minimally invasive prostatectomy (MIP) has increased in popularity over the past decade. We analyzed how the increasing prevalence of MIP has affected the outcomes of MIP and open radical prostatectomy (RRP). Methods: In the Nationwide Inpatient Sample, 23,473 patients undergoing MIP and 118,266 undergoing RRP between 2002 and 2008 are reported. We analyzed length of stay (LOS), hospital charges (THC), complication rates (CR), and socioeconomic characteristics. We used the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) to identify complication rates (RRP n=666, and MIP n=2205). Results: The proportion of MIP increased from 1.4% in 2002 to 29.5% in 2008. Mean LOS decreased for MIP (2.4 days in 2002, 1.6 days in 2008) and RRP (3.1 days in 2002, 2.1 days in 2008). Mean THC for MIP decreased ($46k in 2002, $34k in 2008) and increased for RRP ($18k in 2002, $32k in 2008). After 2005, overall CRs of MIP were lower than for RRP. High-volume centers reported lower CRs for both procedures. MIP was associated with fewer transfusions and wound complications. Men living in ZIP codes with the top quartile of yearly mean household income were more likely to undergo MIP than RRP (P<0.001). Although there were more white patients receiving MIP and black or Hispanic patients more frequently underwent RRP, there was no statistically significant difference. Conclusions: Increasing use of MIP led to decreased hospital stay for all patients, increase charges for RRP, and decreased CRs for both MIP and RRP. In recent years, MIP was associated with fewer complications. Charges for RRP have increased over time to approach those for MIP, and patients with increased socio-economic status were more likely to undergo MIP.

Stress urinary incontinence is a financially burdensome and socially isolating problem and can be experienced by men as a result of radical prostatectomy, radiation therapy, or other urologic surgery. Artificial urinary sphincter (AUS) placement for stress urinary incontinence is considered the ‘gold standard’ for male stress urinary incontinence. While initially only placed by specialized prosthetic surgeons, changes in urologic training have made implantation of the device by general urologists more widespread. Additionally, even though a minority of urologists place the majority of implants, many urologists may find themselves caring for patients with these devices even if they have never placed them themselves. For this reason, it is paramount that the urologic surgeon implanting the device and those caring for patients with prostheses are familiar with the various perioperative and postoperative complications of AUS implantation. This review discusses the most commonly reported complications of AUS implantation as well as those that are rarely described. Knowledge of these potential complications is necessary in order to care for patients with urologic implants.

Purpose To investigate how the extent of an ultrasound instructor’s clinical expertise influences the level of hands-on ultrasound competency achieved by clinicians after three-day ultrasound courses in abdominal and emergency ultrasound. The second goal was to determine how physicians in residency rate the sonographic and didactic skills of student instructors compared to medical staff instructors. Method A total of N = 100 residents participating in a 3-day ultrasound workshop were randomly trained either by 15 student instructors or by clinical staff physicians, both with > 2 years of teaching experience. Both instructor groups had previously completed 120 hours of didactic instructor training. Ultrasound competencies were assessed by a standardized objective structured clinical examination (OSCE) of healthy individuals. The sonographic and didactic skills of both instructor groups were rated by questionnaires with six-step Likert items (1 = excellent, 6 = poor). Results The cohort, trained by student instructors, achieved the same scoring level as the second cohort, trained by physician instructors (mean score 76.4, versus 73.7 of max. 100 points, p = 0.28) in the final OSCE. The sonographic qualification was rated for student educators as 1.44 (mean) [1.1–1.62], versus residents 1.46 [1.26–1.61], versus attendings 1.29 [1.05–1.61]. Didactic skill levels were rated without significant differences with means of 1.53, 1.57 and 1.53, respectively. Discussion & Conclusion The didactic competence of student instructors does not differ statistically from the competency levels of experienced physicians. In terms of the acquired ultrasound skills of trainees, our data indicate that student instructors can be as efficient as staff instructors. Therefore, student instructors can be employed as resource-saving ultrasound educators without decreasing the skills level achieved by course participants, provided that they previously underwent a comprehensive didactic and sonographic training program.
