A BURST-BAUS consensus document for best practice in the conduct of scrotal exploration for suspected testicular torsion: the Finding consensus for orchIdopeXy In Torsion (FIX-IT) study.

OBJECTIVES: To produce a best practice consensus guideline for the conduct of scrotal exploration for suspected testicular torsion using formal consensus methodology. MATERIALS AND METHODS: A panel of 16 expert urologists, representing adult, paediatric, general, and andrological urology used the RAND/UCLA Appropriateness Consensus Methodology to score a 184 statement pre-meeting questionnaire on the conduct of scrotal exploration for suspected testicular torsion. The collated responses were presented at a face-to-face online meeting and each item was rescored anonymously after a group discussion, facilitated by an independent chair with expertise in consensus methodology. Items were scored for agreement and consensus and the items scored with consensus were used to derive a set of best practice guidelines. RESULTS: Statements scored as with consensus increased from Round 1 (122/184, 66.3%) to Round 2 (149/200, 74.5%). Recommendations were generated in ten categories: consent, assessment under anaesthetic, initial incision, intraoperative decision making, fixation, medical photography, closure, operation note, logistics and follow-up after scrotal exploration. Our statements assume that the decision to operate has already been made. Key recommendations in the consent process included the discussion of the possibility of orchidectomy and the possibility of subsequent infection of the affected testis or wound requiring antibiotic therapy. If after the examination under anaesthesia, the index of suspicion of testicular torsion is lower than previously thought, then the surgeon should still proceed to scrotal exploration as planned. A flow chart guiding decision making dependent on intraoperative findings has been designed. If no torsion is present on exploration and the bell clapper deformity is absent, the testis should not be fixed. When fixing a testis using sutures, 3 or 4-point is acceptable and non-absorbable sutures are preferred. CONCLUSIONS: We have produced consensus recommendations to inform best practice in the conduct of scrotal exploration for suspected testicular torsion.

Practical recommendations of the EAU-ESPU guidelines committee for monosymptomatic enuresis-Bedwetting.

BACKGROUND AND AIMS: The objective of this update of the EAU-ESPU guidelines recommendations for nocturnal enuresis was to review the recent published literature of studies, reviews, guidelines regarding the etiology, diagnosis and treatment options of nocturnal enuresis and transform the information into a practical recommendation strategy for the general practitioner, pediatrician, pediatric urologist and urologist. MATERIAL AND METHODS: Since 2012 a monthly literature search using Scopus® was performed and the relevant literature was reviewed and prospectively registered on the European Urology bedwetting enuresis resource center (http://bedwetting.europeanurology.com/). In addition, guideline papers and statements of the European Society for Paediatric Urology (ESPU), the European Association of Urology (EAU), the National Institute for Health and Care Excellence (NICE) and the International Children Continence Society (ICCS) were used to update the knowledge and evidence resulting in this practical recommendation strategy. Recommendations have been discussed and agreed within the working group of the EAU-ESPU guidelines committee members. RESULTS: The recommendations focus to place the child and his family in a control position. Pragmatic analysis is made of the bedwetting problem by collecting voiding and drinking habits during the day, measuring nighttime urine production and identification of possible risk factors such as high-volume evening drinking, nighttime overactive bladder, behavioral or psychological problems or sleep disordered breathing. A questionnaire will help to identify those risk factors. CONCLUSION: Motivation of the child is important for success. Continuous involvement of the child and the family in the treatment will improve treatment compliance, success and patient satisfaction.

EAU-ESPU guidelines recommendations for daytime lower urinary tract conditions in children.

The objective is to review the literature related to lower urinary tract (LUT) conditions in children to conceptualize general practice guidelines for the general practitioner, pediatrician, pediatric urologist, and urologist. PubMed was searched for the last 15-year literature by the committee. All articles in peer-review journal-related LUT conditions (343) have been retrieved and 76 have been reviewed extensively. Prospective trials were few and the level of evidence was low. Most of the recommendations have been done by committee consensus after extensive discussion of literature reports. History taking is an integral part of evaluation assessing day- and nighttime urine and bowel control, urgency, and frequency symptoms. Exclusion of any neurogenic and organic cause is essential. Uroflowmetry and residual urine determination are recommended in all patients to evaluate bladder emptying. Urodynamic studies are reserved for refractory or complicated cases. Urotherapy that aims to educate the child and family about bladder and bowel function and guides them to achieve normal voiding and bowel habits should initially be employed in all cases except those who have urinary tract infections (UTI) and constipation. Specific medical treatment is added in the case of refractory overactive bladder symptoms and recurrent UTIs.Conclusion: Producing recommendations for managing LUTS in children based on high-quality studies is not possible. LUTS in children should be evaluated in a multimodal way by minimal invasive diagnostic procedures. Urotherapy is the mainstay of treatment and specific medical treatment is added in refractory cases.What is Known:• Symptoms of the lower urinary tract may have significant social consequences and sometimes clinical morbidities like urinary tract infections and vesicoureteral reflux. In many children, however, there is no such obvious cause for the incontinence, and they are referred to as having functional bladder problems.What is New:• This review aims to construct a practical recommendation strategy for the general practitioner, pediatrician, pediatric urologist, and urologist for LUTS in children. Producing recommendations for managing LUTS in children based on high-quality studies is not possible. LUTS in children should be evaluated in a multimodal way by minimal invasive diagnostic procedures. Urotherapy is the mainstay of treatment and specific medical treatment is added in refractory cases.

Impact of intraoperative distractions on patient safety: a prospective descriptive study using validated instruments.

BACKGROUND: There is emerging evidence indicating that distractions in the operating room (OR) are prevalent. Studies have shown a negative impact of distractions, but they have been conducted mostly with residents in simulated environments. We tested the hypothesis that intraoperative distractions are associated with deterioration in patient safety checks in the OR. METHODS: We assessed 24 elective urologic procedures. Blinded trained assessors (two surgeons, one psychologist) used validated instruments to prospectively assess in vivo frequency and severity of distractions (related to communication, phones/pagers, equipment/provisions, OR environment, other hospital departments, or a member of the OR team) and completion of safety-related tasks (related to the patient, equipment, and communication). Descriptive and correlational analyses were conducted. RESULTS: Mean case duration was 70 min (mean intraoperative time 31 min). A mean of 4.0 communication distractions (range 0-9) and 2.48 other distractions (range 0-5) were recorded per case (distraction rate of one per 10 min). Distractions from external visitors (addressed to the entire team or the surgeon) and distractions due to lack of coordination between hospital departments were most disruptive. Regarding safety checks, patient tasks were completed most often (85-100 %) followed by equipment tasks (75-100 %) and communication tasks (55-90 %). Correlational analyses showed that more frequent/severe communication distractions were linked to lower completion of patient checks intraoperatively (median rho -0.56, p < 0.05). CONCLUSIONS: Distractions are prevalent in ORs and in this study were linked to deterioration in intraoperative patient safety checks. Surgeons should be mindful of their tolerance to distractions. Surgical leadership can help control distractions and reduce their potential impact on patient safety and performance.

Adaptive strategies used by surgical teams under pressure: an interview study among senior healthcare professionals in four major hospitals in the United Kingdom.

BACKGROUND: Healthcare systems are operating under substantial pressures, and often simply cannot provide the standard of care they aspire to within the available resources. Organisations, managers, and individual clinicians make constant adaptations in response to these pressures, which are typically improvised, highly variable and not coordinated across clinical teams. The purpose of this study was to identify and describe the types of everyday pressures experienced by surgical teams and the adaptive strategies they use to respond to these pressures. METHODS: We conducted interviews with 20 senior multidisciplinary healthcare professionals from surgical teams in four major hospitals in the United Kingdom. The interviews explored the types of everyday pressures staff were experiencing, the strategies they use to adapt, and how these strategies might be taught to others. RESULTS: The primary pressures described by senior clinicians in surgery were increased numbers and complexity of patients alongside shortages in staff, theatre space and post-surgical beds. These pressures led to more difficult working conditions (e.g. high workloads) and problems with system functioning such as patient flow and cancellation of lists. Strategies for responding to these pressures were categorised into increasing or flexing resources, controlling and prioritising patient demand and strategies for managing the workload (scheduling for efficiency, communication and coordination, leadership, and teamwork strategies). CONCLUSIONS: Teams are deploying a range of strategies and making adaptations to the way care is delivered. These findings could be used as the basis for training programmes for surgical teams to develop coordinated strategies for adapting under pressure and to assess the impact of different combinations of strategies on patient safety and surgical outcomes.

Development of a high fidelity, multidisciplinary, crisis simulation model for robotic surgical teams.

Immediate access to the patient in crisis situations, such as cardiac arrest during robotic surgery, can be challenging. We aimed to present a full immersion simulation module to train robotic surgical teams to manage a crisis scenario, enhance teamwork, establish clear lines of communication, improve coordination and speed of response. Start time of cardiopulmonary resuscitation (CPR), first defibrillator shock and robotic de-docking time from the first 'cardiac arrest call' were recorded. Observational Teamwork Assessment for Surgery (OTAS) scores were used in control and test simulations to assess performance along with a participant survey. Repeat scenarios and assessment were conducted at a 6-month interval for the same team to validate knowledge retention and an additional scenario was run with a new anaesthetic team to validate modular design. OTAS scores improved across all specialty teams after training with emergency algorithm and at retention validity re-test (p = 0.0181; p = 0.0063). There was an overall reduction in time to CPR (101-48 s), first defibrillator shock (> 302 s to 86 s) and robot de dock time (86-25 s) Improvement remained constant at retention validity re-test. Replacing the anaesthetic team showed improvement in time to CPR, first shock and robotic de-dock times and did not affect OTAS scores (p = 0.1588). The module was rated highly for realism and crisis training by all teams. This high-fidelity simulation training module is realistic and feasible to deliver. Its modular design allows for efficient assessment and feedback, optimising staff training time and making it a valuable addition to robotic team training.

Framework for incorporating simulation into urology training.

OBJECTIVES: • Changes to working hours, new technologies and increased accountability have rendered the need for alternative training environments for urologists. • Simulation offers a promising arena for learning to take place in a safe, realistic setting. • Despite its benefits, the incorporation of simulation into urological training programmes remains minimal. • The current status and future directions of simulation for training in technical and non-technical skills are reviewed as they pertain to urology. • A framework is presented for how simulation-based training could be incorporated into the entire urological curriculum. MATERIALS AND METHODS: • The literature on simulation in technical and non-technical skills training is reviewed, with a specific focus upon urology. RESULTS: • To fully integrate simulation into a training curriculum, its possibilities for addressing all the competencies required by a urologist must be realized. • At an early stage of training, simulation has been used to develop basic technical skills and cognitive skills, such as decision-making and communication. • At an intermediate stage, the studies focus upon more advanced technical skills learnt with virtual reality simulators. • Non-technical skills training would include leadership and could be delivered with in situ models. • At the final stage, experienced trainees can practise technical and non-technical skills in full crisis simulations situated within a fully-simulated operating rooms. CONCLUSIONS: • Simulation can provide training in the technical and non-technical skills required to be a competent urologist. • The framework presented may guide how best to incorporate simulation into training curricula. • Future work should determine whether acquired skills transfer to clinical practice and improve patient care.

Observational teamwork assessment for surgery: construct validation with expert versus novice raters.

OBJECTIVE: To test the construct validity of the Observational Teamwork Assessment for Surgery (OTAS) tool. SUMMARY BACKGROUND DATA: Poor teamwork in surgical teams has been implicated in adverse events to patients. The OTAS is a tool that assesses teamwork in real time for the entire surgical team. Existing empirical research on OTAS has yet to explore how expert versus novice tool users use the tool to assess teamwork in the operating room. METHODS: Data were collected in 12 elective procedures by an expert/expert (N = 6) and an expert/novice (N = 6) pair of raters. Five teamwork behaviors (communication, coordination, leadership, monitoring, and cooperation) were scored via observation pre, intra, and postoperatively by blind raters. RESULTS: Significant and sizeable correlations were obtained in 12 of 15 behaviors in the expert/expert pair, but only in 3 of 15 behaviors in the expert/novice pair. Significant differences in mean scores were obtained in 3 of 15 behaviors in the expert/expert pair, but in 11 of 15 behaviors in the expert/novice pair. Total OTAS scores exhibited strong correlations and no significant differences in ratings in the expert/expert pair. In the expert/novice pair no correlations were obtained and there were significant differences in mean scores. The overall size of inconsistency in the scoring was 2% for expert/expert versus 15% for expert/novice. CONCLUSIONS: OTAS exhibits adequate construct validity as assessed by consistency in the scoring by expert versus novices-ie, expert raters produce significantly more consistent scoring than novice raters. Further validation should assess the learning curve for novices in OTAS. Relationships between OTAS, measures of technical skill, and behavioral responses to surgical crises should also be quantified.

Treatment of Varicocele in Children and Adolescents: A Systematic Review and Meta-analysis from the European Association of Urology/European Society for Paediatric Urology Guidelines Panel.

CONTEXT: The benefits and harms of intervention (surgical or radiological) versus observation in children and adolescents with varicocele are controversial. OBJECTIVE: To systematically evaluate the evidence regarding the short- and long-term outcomes of varicocele treatment in children and adolescents. EVIDENCE ACQUISITION: A systematic review and meta-analysis was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) statement. A priori protocol was registered to PROSPERO (CRD42018084871), and a literature search was performed for all relevant publications published from January 1980 until June 2017. Randomized controlled trials (RCTs), nonrandomized comparative studies (NRSs), and single-arm case series including a minimum of 50 participants were eligible for inclusion. EVIDENCE SYNTHESIS: Of 1550 articles identified, 98 articles including 16 130 patients (7-21 yr old) were eligible for inclusion (12 RCTs, 47 NRSs, and 39 case series). Varicocele treatment improved testicular volume (mean difference 1.52ml, 95% confidence interval [CI] 0.73-2.31) and increased total sperm concentration (mean difference 25.54, 95% CI 12.84-38.25) when compared with observation. Open surgery and laparoscopy may have similar treatment success. A significant decrease in hydrocele formation was observed in lymphatic sparing versus non-lymphatic sparing surgery (p=0.02). Our findings are limited by the heterogeneity of the published data, and a lack of long-term outcomes demonstrating sperm parameters and paternity rates. CONCLUSIONS: Moderate evidence exists on the benefits of varicocele treatment in children and adolescents in terms of testicular volume and sperm concentration. Current evidence does not demonstrate superiority of any of the surgical/interventional techniques regarding treatment success. Long-term outcomes including paternity and fertility still remain unknown. PATIENT SUMMARY: In this paper, we review benefits and harms of varicocele treatment in children and adolescents. We found moderate evidence that varicocele treatment results in improvement of testicular volume and sperm concentration. Lymphatic sparing surgery decreases hydrocele formation. Paternity and fertility outcomes are not clear.

Laparoscopy simulators.

To reduce the complication rate associated with laparoscopic surgery and to improve training, several simulators have been incorporated into training curricula and skills courses. We discuss the advantages and disadvantages and compare the different types of simulators available. We also reviewed the literature to assess the acquisition of skills using these simulators and their transfer to real operations. It is important to realize that currently, any form of simulation is merely an adjunct to, and not a replacement for, traditional methods of training and that supervision and feedback are essential. More collaboration is needed between urologists and simulator companies to produce operation-specific simulated modules for urologic procedures.

Recording of drug allergies: are we doing enough?

OBJECTIVE: To assess the implementation of local and national guidelines concerning documentation of drug/clinical hypersensitivities. DESIGN: Audit with retrospective and prospective components used to assess the process of drug hypersensitivity documentation. PATIENTS: Fifty surgical inpatients' notes were retrospectively analysed followed by 63 patients prospectively. SETTING: West London teaching hospital. MAIN OUTCOME MEASURES: Drug hypersensitivity status correctly indicated on clinical notes, drug 'Kardex' charts, and anaesthetic records; these three documents were to concur. Hypersensitivities qualified according to symptoms experienced. RECOMMENDATIONS: Standardization of preoperative clinical notes and multidisciplinary responsibility for records between doctor, nurse and pharmacist. RESULTS: Hypersensitivity documentation in clinical notes improved by 7% after the introduction of a formalized history sheet for preoperative clinics. These were based upon the anaesthetic charts, which had demonstrated 100% documentation previously. Considerable improvements (70.8%) in the clarification of adverse reaction symptoms post recommendation were shown; this was also attributed to the new history sheet. Concurrence improved by 2%. CONCLUSIONS: The original study revealed areas for improvement and provided part of the solution--a more standardized preoperative assessment tool. Multidisciplinary cooperation in addition to formalizing the assessment process has led to a more efficient and safer service for patient and medicolegally for health care professionals. KEY MESSAGES: (1) Standardized forms, for the recording of clinical information preoperatively, ensure relevant guidelines are implemented in practice. (2) Multidisciplinary teams provide a vital safety net for their patients and colleagues.

Role of antibiotic prophylaxis in antenatal hydronephrosis: A systematic review from the European Association of Urology/European Society for Paediatric Urology Guidelines Panel.

BACKGROUND: The benefits and harms of continuous antibiotic prophylaxis (CAP) versus observation in patients with antenatal hydronephrosis (ANH) are controversial. OBJECTIVE: The aim was to determine the effectiveness of CAP for ANH, and if beneficial to determine the best type and regimen of antibiotic and the most harmful to provide guidance for clinical practice. METHODS: A systematic literature search was performed in databases including Medline, Embase, and Cochrane in June 2015. The protocol was prospectively registered to PROSPERO (CRD42015024775). The search started from 1980, when maternal ultrasound was first introduced into clinical practice. Eligible studies were critically evaluated for risk of bias using Revman software. The outcomes included reduction in urinary tract infections (UTI), drug-related adverse events and kidney functions. RESULTS: Of 797 articles identified, 57 full text articles and six abstracts were eligible for inclusion (2 randomized controlled trials, 11 non-randomized comparative studies, and 50 case series). It remains unclear whether CAP is superior to observation in decreasing UTIs. No conclusion could be drawn for drug-related adverse events and kidney function because of lack of data. Children who were not circumcised, with ureteral dilatation, and high-grade hydronephrosis may be more likely to develop UTI, and CAP may be warranted for these subgroups of patients. A majority of the studies had low-to-moderate quality of evidence and with high risk of bias. CONCLUSIONS: The benefits of CAP in a heterogeneous group of children with ANH involving different etiologies remains unproven. However, the evidence in the form of prospective and retrospective observational studies has shown that it reduces febrile UTI in particular subgroups.

Training junior operative residents in laparoscopic suturing skills is feasible and efficacious.

BACKGROUND: Laparoscopic suturing has been regarded as an advanced operative task, and courses to develop this skill are aimed at senior trainees and consultants. This study evaluates the role of laparoscopic suturing courses in the modern operative training curriculum. METHODS: The performance of 9 senior operative trainees (course A) was compared to that of 14 junior operative trainees (course B) at identical, 2-day laparoscopic suturing courses. Pre- and post-course assessments measured time taken, dexterity, and quality for the placement of 1 intracorporeal suture on synthetic bowel. Post-course data was compared to the performance of a group of 6 experts. RESULTS: The median number of laparoscopic procedures carried out unassisted was 130 for surgeons on course A, and 0 for those on course B. At the pre-course assessment, senior trainees (course A) were significantly faster, more dexterous, and had higher checklist scores then those on course B. Both groups had improved significantly by the end of each the course. Post-course comparison between the 2 groups showed equivalent path length and checklist scores, although group A remained faster (P = .003) and made fewer movements (P = .033). Senior trainees had similar performance data to the group of expert surgeons, although this was not the case for junior trainees. CONCLUSIONS: Endoscopic suturing is a task that can be learned by operative trainees during short skills courses, regardless of baseline laparoscopic experience. Skills training in laparoscopic suturing should thus not be reserved only for those contemplating advanced laparoscopic operation.

Teamwork in the operating theatre: cohesion or confusion?

RATIONALE: The aim of the research that we report here was to empirically assess the cohesiveness of the multidisciplinary operating theatre (OT) team. METHOD: We used concepts from the team performance and team mental models literature to assess OT professionals' perceptions of their teamwork, the structure of their teams and their respective roles within them and their teams' performance. RESULTS: Team structure: OT professionals would welcome a change from the current structure of the team, although there was no agreement on what that structure is. Nurses perceived the team as unitary, surgeons and anaesthetists perceived it as comprising multiple subteams. Team roles: OT professionals tended to overrate their own understanding of their colleagues' role in the OT relative to the role understanding that the colleagues attributed to them. This tendency was especially marked for the surgeons. Team communication and team performance: OT professionals agreed on the relative importance of the various communicating pairs in the OT. Moreover, they were satisfied with the quality of communication among them, except for the communication between the surgeon and the anaesthetist, which received lower ratings. Finally, the quality of the teamwork in the OT was deemed acceptable, although there is room for improvement. CONCLUSIONS: The OT environment need not be as cohesive as previously assumed--a finding that carries implications for the effectiveness of team training interventions. Further research is needed in order to fully comprehend the dynamics of the OT as a working environment and, most importantly, their relation to patient safety.

Management of undescended testes: European Association of Urology/European Society for Paediatric Urology Guidelines.

CONTEXT: Undescended testis is the most common endocrinological disease in the male newborn period. Incidence varies between 1.0% and 4.6% in full-term neonates, with rates as high as 45% in preterm neonates. Failure or delay of treatment can result in reduced fertility and/or increased testicular cancer risk in adulthood. OBJECTIVE: To provide recommendations for the diagnosis and treatment of boys with undescended testes which reduce the risk of impaired fertility and testicular cancer in adulthood. EVIDENCE ACQUISITION: Embase and Pubmed were searched for all relevant publications, from 1990 to 2015 limited to English language. Data were narratively synthesized in light of methodological and clinical heterogeneity. The risk of bias of each included study was assessed. EVIDENCE SYNTHESIS: There is consensus that early treatment, by 18 months at the latest, for undescended testes is mandatory to avoid possible sequelae regarding fertility potential and cancer risk. The current standard therapy is orchidopexy, while hormonal therapy is still under debate. However, in some individuals the successful scrotal placement of previously undescended testes may not prevent potential negative long-term outcomes regarding fertility and testicular malignancy. CONCLUSIONS: There is good evidence for early placement of undescended testes in the scrotal position to prevent potential impairment of fertility and reduce the risk of testicular malignancy. No consensus exists on the various forms of hormonal treatment, which are assessed on an individual basis.

Assessment of psychomotor skills acquisition during laparoscopic cholecystectomy courses.

BACKGROUND: Standardized short courses in laparoscopic cholecystectomy aim to teach laparoscopic skills to surgical trainees, although end-of-course assessments of performance remain subjective. The current study aims to objectively assess psychomotor skills acquisition of trainees attending laparoscopic cholecystectomy courses. METHODS: Thirty-seven junior surgical trainees had their laparoscopic skills assessed before and after attending 1 of 3 separate 2-day courses (A, B, and C), all with identical format. Assessments were comprised of a standardized simulated laparoscopic task, with performance measured using a valid electromagnetic hand-motion tracking device. RESULTS: Overall, trainees made significant improvements in path length (P=.006), number of movements (P<.001), and time taken (P<.001). Analyzing the 3 courses separately, only trainees attending courses A and C made significant improvements. DISCUSSION: Objective validated methods can be used to assess learning of psychomotor skills on courses. In addition to providing participants with an insight into their skills, these data can be used to demonstrate course efficacy.

Laparoscopic task recognition using Hidden Markov Models.

Surgical skills assessment has been paid increased attention over the last few years. Stochastic models such as Hidden Markov Models have recently been adapted to surgery to discriminate levels of expertise. Based on our previous work combining synchronized video and motion analysis we present preliminary results of a HMM laparoscopic task recognizer which aims to model hand manipulations and to identify and recognize simple surgical tasks.

Single incision prone retroperitoneoscopic paediatric nephrectomy.

OBJECTIVE: We have previously reported our early experience (2 patients) of single-incision nephrectomy via the retroperitoneal prone route using an advanced access platform (GelPOINT Mini). Here, we review our series to date and also present a detailed video demonstrating the technique. METHOD: In the prone position, a single transverse incision was made at the midpoint on a line along the lateral border of erector spinae bounded by the lower border of the 12th rib and iliac crest. Posterior abdominal muscles were split and the deep lumbodorsal fascia incised. The Alexis retractor was positioned and the Gel-Seal cap with low-profile sleeves locked in place. Hilar vessels were divided by endoclip application or harmonic scalpel. The kidney was retrieved directly or via an endobag. The Alexis retractor was removed and wound closed with absorbable sutures. RESULTS: Between July 2013 and March 2015, we have used this approach to perform 10 nephrectomies in nine patients (4 male and 5 female). The median age at nephrectomy was 10.9 years (range 2.7-15.9 years). The median kidney length was 7.5 cm (range 3.7-11.5 cm). No complications occurred and none converted to open procedure. CONCLUSION: Single incision retroperitoneal nephrectomy is feasible, safe, and provides excellent cosmesis.

"Pass the ball!" Simultaneous flexible nephroscopy and retrograde intrarenal surgery for large residual upper-pole staghorn stone.

Complex staghorn calculi have conventionally been treated with percutaneous nephrolithotomy, extracorporeal lithotripsy, or, occasionally, open surgery. Access to branched calculi is difficult through a single percutaneous track. We tested and make a case for a synchronous bidirectional technique combining the use of flexible instruments through percutaneous and retrograde approaches. We present a case of "pass the ball," which may have a place in tackling large, complex, or branched staghorn calculi without the need for multiple percutaneous punctures, removing larger fragments than is possible through the ureter and avoiding multiple passes through the ureter, saving time and decreasing the possibility of iatrogenic ureteral injury.

Using manual dexterity to predict the quality of the final product in the small bowel anastomosis after a period of training.

OBJECTIVE: The use of aptitude tests in the selection of surgeons has gained recent attention. Few have described its relevance in predicting the acquisition of surgical techniques. We aim to show whether assessing manual dexterity can predict the quality of the final product after a period of training. METHODS: Thirty-six medical students had their manual dexterity assessed completed bench model small bowel anastomosis in 8 consecutive sessions. The fine details (accuracy (number of sutures that traversed full thickness) and number of sutures placed) and gross details (bowel apposition) of quality of final product was objectively assessed. RESULTS: Manual dexterity correlated with grade only in the initial sessions (Pearson correlation coefficient, r = -.578, P < .01). There was no significant correlation with the fine details with any session. CONCLUSIONS: There was a correlation with manual dexterity and outcome measures in the initial sessions of training with grade only. This relationship was eliminated by the end of training sessions. This suggests that the outcome of procedures after a period of training cannot be predicted by measuring manual dexterity skills.
