RESUMO

BACKGROUND: In this meta-analysis, we aimed to compare the hydrocelectomy versus aspiration and sclerotherapy for treating primary hydrocele. METHODS: We included randomized controlled trials (RCTs) and quasi-RCTs that compared aspiration and sclerotherapy with any type of sclerosants versus hydrocelectomy for primary hydrocele. Studies were identified via a systematic search of the Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, and ClinicalTrials.gov. Citation tracking of related articles was performed. Data extraction and quality assessment were performed independently by two authors. The primary and secondary outcome measures were compared and analyzed using the Review Manager 5.3.5 software. RESULTS: Five small RCTs were included in the present study. These 5 RCTs included 335 patients with 342 hydroceles, randomized to aspiration and sclerotherapy (185 patients; 189 hydroceles) and surgery (150 patients; 153 hydroceles). There was no significant difference in clinical cure between sclerotherapy and hydrocelectomy (RR 0.45, 95% CI 0.18 to 1.10). Meta-analysis revealed a significant increase in recurrence in the sclerotherapy group compared with the surgical group (RR 9.43, 95% CI 1.82 to 48.77). There were no significant differences between the two groups in assessing fever, infection, and hematoma. CONCLUSION: Aspiration and sclerotherapy is an efficient technique with a higher recurrent rate; therefore, we recommend aspiration and sclerotherapy for patients at high risk for surgery or avoiding surgery. In addition, included RCTs had low methodological quality, low sample size, and invalidated instruments for outcome assessment. Therefore, there is a great need for further methodologically rigorous RCTs with the registered protocol.

RESUMO

BACKGROUND: Delay of emergency surgery contributes to morbidity and mortality, and physiologic status affects outcomes of patients requiring emergent surgery. Our purpose was to determine whether delays to emergent surgery in children were associated with increased major morbidity or mortality in a risk-adjusted population. METHODS: We performed a retrospective review of class 1 (≤ 60 min to operating room) surgical procedures from July 11, 2011, to July 30, 2016, at BC Children's Hospital, Vancouver. Data sources included the operating room database, patient charts, American Society of Anesthesiologists classification, Neonatal Acute Physiology (SNAP II) and Pediatric Risk of Mortality (PRISM III) scores, time from booking to operating room and outcome. Patients were classified as being at low or high risk for death. We defined major morbidity as unintended loss of an organ, limb or function related to surgery, and delay to surgery as more than 60 minutes from booking to in room. We used the χ2 test for univariate analysis and logistic regression for multivariate analysis. RESULTS: There were 384 cases (367 patients), 223 high-risk and 161 low-risk. The median age was 4 years (range 0 d-18 yr). Overall, 184 cases (47.9%) were delayed. Major morbidity occurred in 94 cases (24.5%), and 28 patients (7.6%) (all in the high-risk group) died. The mean time to the operating room was 1.46 hours for patients with major morbidity/mortality and 1.17 hours for those without. After adjustment for risk level, multivariate analysis showed delay to surgery to be associated with 85% increased odds of morbidity and/or mortality (adjusted odds ratio 1.85, 95% confidence interval 1.20-2.94) compared to no delay. CONCLUSION: Delay to emergent surgery was associated with a significant increase in major morbidity and/or mortality. Children who require emergency surgery need their care prioritized by not only operating room teams but also hospitals and government; otherwise, they will continue to experience unintended consequences.

RESUMO

PURPOSE: Surgical site infections (SSIs) are a significant determinant of morbidity in the Neonatal Intensive Care Unit (NICU). Chlorhexidine gluconate/isopropyl alcohol (CHG-IPA) skin prep has demonstrated superiority over Povidone-Iodine (PI) in preventing SSIs in adults, however FDA labeling discourages CHG use in infants <2 months. This project aimed to i) create evidence for safe CHG skin antisepsis in neonates; and ii) evaluate the safety and effectiveness of CHG skin prep for neonatal surgery. METHODS: A literature review was conducted to assess the safety and effectiveness of neonatal CHG skin antisepsis. Following stakeholder engagement, a CHG surgical skin prep protocol and validated neonatal skin integrity tool to assess prep-associated skin injury were implemented in 50 consecutive, eligible neonates ≥1500 g and ≥34 weeks post conceptual age undergoing abdominal or thoracic surgery. SSI rates were compared to a matched, historical PI skin prep cohort. RESULTS: 2%CHG-70%IPA or 0.5%CHG-70%IPA were used based on gestational age cutoffs. None of the CHG patients experienced adverse skin prep outcomes while 8% developed SSIs, compared to 14% in the historical PI cohort. CONCLUSION: This project engaged NICU stakeholders in quality improvement work and informed the implementation of a safe and effective CHG skin prep protocol for neonatal surgery. LOE: IV.

RESUMO

INTRODUCTION: Access to pediatric urological surgery is low in low-and-middle income countries (LMICs). Pediatric Urological missions have often been undertaken without best practice guidelines. Many strides have been made in pediatric general surgery and other surgery but little in pediatric urology as a component of global surgery. STUDY AIMS: The purpose of this study was to identify challenges to delivery of pediatric urological care in LMICs and make recommendations for its advancement. STUDY DESIGN: An internet search for reports and websites was undertaken. Published surveys from Global Initiative for Children Surgery (GICS) and American Pediatric Surgical Association (APSA) were evaluated. We developed and administered an additional questionnaire. Respondents included LMIC pediatric surgeons, HIC pediatric surgeons and HIC pediatric urologists and LMIC urologists and general surgeons. RESULTS: Most global surgical visits were short one-time visit, and respondents citing complex pediatric urologic patients as most neglected in LMICs with the main challenge reported as a lack of specialist surgeons, poor communication between groups and poor infrastructure. Local specialist training was universally recommended as the most effective way to address unmet needs, although the form of training was not clear. DISCUSSION: Most published work has looked at global general surgery or pediatric general surgery [1][2][3][6][8][11][13] but little on pediatric urology. Most of the information provided was blog posts of social engagements but rarely did these websites provide information on the surgical experience, challenges and solutions gleaned overtime[41][43][44][45][56] It is recognised by pediatric urologists, general urologists and pediatric surgeons that complex urologic anomalies are the most neglected among children's surgical conditions with a higher disability weight attributed to urologic conditions compared to anorectal conditions. [6][8][14][27][31][36][46], yet there's little expertise on ground and many challenges to its advancement. This study was limited by the number of questions we could explore due to the need to make questions fewer and more concise. CONCLUSIONS: Pediatric urological conditions remain among the most neglected in global surgery. Current missions face significant challenges that may result in suboptimal outcomes. A comprehensive effort to establish guidelines for these missions is imperative.

RESUMO

BACKGROUND: Narrative data about the patient experience of surgery can help healthcare professionals and administrators better understand the needs of patients and their families as well as provide a foundation for improvement of procedures, processes and services. However, units often lack a methodological framework to analyse these data empirically and derive key areas for improvement. The American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) is aimed at improving the quality of surgical care by collecting patient data and reporting risk-adjusted surgical outcomes for each participant hospital in the programme. Though qualitative data about patient experience are captured as part of the NSQIP database, to date no framework or methodology has been proposed, or reported on, to analyse these data for the purposes of quality improvement. The goal of this study was to demonstrate the feasibility of using content analysis to empirically derive key areas for quality improvement from a sample of 3601 narrative comments about paediatric surgery from patients and families at British Columbia Children's Hospital. STUDY DESIGN: Thematic content analysis conducted on a total of 3601 patient and family narratives received between 2011 and 2018. RESULTS: Overall satisfaction with care was high and experiences with healthcare providers at the hospital were positive. Areas for improvement were identified in the themes of health outcomes, communication and surgery timelines. Results informed follow-up interprofessional quality improvement initiatives. CONCLUSIONS: Recording and analysing patient experience data as part of validated quality improvement programmes such as ACS NSQIP can provide valuable and actionable information to improve quality of care.

RESUMO

BACKGROUND/PURPOSE: Elimination of unnecessary practice variation through standardization creates opportunities for improved outcomes and cost-effectiveness. A quality improvement (QI) initiative at our institution used evidence and consensus to standardize management of gastroschisis (GS) from birth to discharge. METHODS: An interdisciplinary team utilized best practice evidence and expert opinion to standardize GS care. Following stakeholder engagement and education, care standardization was implemented in September 2014. A comparative cohort study was conducted on consecutive patients treated before (n=33) and after (n=24) standardization. Demographic, treatment, and outcome measures were collected from a prospective GS registry. Direct costs were estimated, and protocol compliance was audited. RESULTS: BW, GA, and bowel injury severity were comparable between groups. Key practice changes were: closure technique (pre-88% primary fascial, post-83% umbilical cord flap; p<0.001), closure location (pre-97% OR, post-67% NICU; p<0.001), and GA avoidance (pre-0%, post-48%; p<0.001). Median post-closure ventilation days were shorter (pre-4, post-1; p<0.001), and SSI rates trended lower (pre-21%, post-8%; p=0.3) in the post-implementation group with no differences in TPN days or LOS. No significant difference was seen in average per-patient costs: pre-$85,725 ($29,974-221,061), post-$76,329 ($14,205-176,856). CONCLUSION: Care standardization for GS enables practice transformation, cost-effective outcome improvement, and supports an organizational culture dedicated to continuous improvement. LEVEL OF EVIDENCE: III.

RESUMO

INTRODUCTION: Anthropometric measurements can be used to define pediatric malnutrition. Our study aims to: (1) characterize the preoperative nutritional status of children undergoing abdominal or thoracic surgery, and (2) describe the associations between WHO-defined acute (stunting) and chronic (wasting) undernutrition (Z-scores <-2) and obesity (BMI Z-scores >+2) with 30-day postoperative outcomes. METHODS: We queried the Pediatric NSQIP Participant Use File and extracted data on patients' age 29days to 18years who underwent abdominal or thoracic procedures. Normalized anthropometric measures were calculated, including weight-for-height for <2years, BMI for ages ≥2years, and height for age. Logistic regression models were developed to assess nutritional outlier status as an independent predictor of postoperative outcome. RESULTS: 23,714 children (88% ≥2y) were evaluated. 4272 (18%) were obese, while 2640 (11.1%) and 904 (3.8%) were stunted and wasted, respectively, after controlling for gender, ASA/procedure/wound classification, preoperative steroid use, need for preoperative nutritional support, and obese children had higher odds of SSIs (OR 1.29, 95% CI 1.1-1.5, p=0.001), while stunted children were at increased risk of any 30-day postoperative complication (OR 1.16, 95% CI 1.0-1.3, p=0.036). CONCLUSION: Children who are stunted or obese are at increased risk of adverse outcome after abdominal or thoracic surgery. LEVEL OF EVIDENCE: III.

RESUMO

BACKGROUND: The prevalence of varicoceles is as high as 15% in children and adolescents. Optimal management of varicoceles has not been consolidated. Options include observation, radiological intervention, or surgical varicocelectomy. OBJECTIVE: Herein, we aim to assess the outcomes of radiological and surgical interventions for varicocele in children and adolescents evaluated by RCTs. STUDY DESIGN: The study subjects were children and adolescents up to 21 years old, diagnosed with varicocele and allocated to receive either "surgical or radiological intervention" or "no treatment". MATERIALS AND METHODS: We searched MEDLINE and EMBASE (Ovid platform), Web of Science, CINAHL, Cochrane Central Register of Controlled Trials, Google Scholar, ClinicalTrials.gov, and the World Health Organization International Clinical Trials Registry Platform for RCTs reporting on varicocele treatment in children and adolescents up to June 23, 2016. Only RCTs with patients aged under 21 years were included. Main outcomes of interest included changes in testicular size, semen analysis parameters, surgical adverse events and failures. RESULTS: Nine eligible studies were included in the systematic review. Meta-analysis based on available outcomes data demonstrated an improvement in testicular volume (mean difference 3.18 mL, 95% CI 1.94-4.42) and in sperm count (mean difference 25.54 × 106/mL, 95% CI 12.84-38.25) in patients who underwent radiological or surgical treatment compared with conservative management. CONCLUSIONS: Based on current available randomized controlled trials, there is low to moderate level of evidence that radiological or surgical treatment of adolescent varicocele is associated with improved testicular size/growth and sperm concentration. The ultimate effects on fertility and paternity rates are not known.

RESUMO

INTRODUCTION: Lymph node counts have become a surrogate measure for the extent and quality of pelvic lymph node dissection (PLND) at radical cystectomy, but little consideration has been given to the methodology of lymph node processing. We report results from a prospective series comparing a conventional protocol for processing PLND specimens to a fat-emulsifying protocol. We hypothesized that the rate of node positivity would increase with the fat-emulsifying protocol. METHODS: Patients undergoing radical cystectomy for cTis-T4aN0-1M0 urothelial carcinoma of the bladder were eligible for this trial. Palpable lymph nodes were isolated from the PLND specimens in the conventional protocol. The remaining tissue was then processed with fat-emulsifying solution to identify further nodes visually. Nodal counts were compared between techniques. RESULTS: The median number of nodes counted in the PLND specimens of 26 patients was 24.5 (range: 20-40) with conventional processing and 37 (range: 24-52) with the fat-emulsifying solution (p < 0.001). Three patients had lymph node positive disease detected by conventional means, and a single patient was found to have a single positive node by the fat-emulsifying solution alone. The study was closed early after conducting a futility analysis. CONCLUSIONS: A fat-emulsifying protocol identified more lymph nodes than a conventional protocol and may be an appropriate method to standardize lymph node processing following PLND. However, we were unable to show that such a standardized approach significantly increased the rate of node positivity in patients undergoing radical cystectomy.

RESUMO

BACKGROUND: Hydrocoeles are common cystic scrotal abnormalities, described as a fluid-filled collection between the visceral and parietal layers of the tunica vaginalis of the scrotum. There are two approaches for treatment of hydrocoeles: surgical open hydrocoelectomy and aspiration followed by sclerotherapy.  OBJECTIVES: We compared the benefits and harms of aspiration and sclerotherapy versus hydrocoelectomy for the management of hydrocoeles. SEARCH METHODS: We searched the Cochrane Renal Group's Specialised Register to 2 August 2014 through contact with the Trials' Search Co-ordinator using search terms relevant to this review. SELECTION CRITERIA: Randomised controlled trials (RCTs) and quasi-RCTs comparing aspiration and sclerotherapy versus hydrocoelectomy for the management of hydrocoeles. DATA COLLECTION AND ANALYSIS: Two authors independently extracted data and assessed risk of bias in the included studies. Random effects meta-analyses were performed using relative risk (RR) for dichotomous outcomes and mean differences (MD) for continuous outcomes, with 95% confidence intervals (CI). MAIN RESULTS: We found four small studies that met the inclusion criteria. These studies enrolled 275 patients with 282 hydroceles. Participants were randomised to aspiration and sclerotherapy (155 patients with 159 hydroceles) and surgery (120 patients with 123 hydroceles). All studies were assessed as having low or unclear risk of bias for selection bias, detection bias, attrition bias and selective reporting bias. Blinding was not possible for participants and investigators based on the type of interventions. Blinding for statisticians was not reported in any of included studies.There were no significant difference in clinical cure between the two groups (3 studies, 215 participants: RR 0.45, 95% CI 0.18 to 1.10), however there was significant heterogeneity (I² = 95%). On further investigation one study contributed all of the heterogeneity. This could be due to the agent used or perhaps due to the fact that this is a much older study than the other two studies included in this analysis. When this study was removed from the analysis the heterogeneity was 0% and the result was significant (in favour of surgery) (2 studies, 136 participants: RR 0.74; 95% CI 0.64 to 0.85).There was a significant increase in recurrence in those who received sclerotherapy compared with surgery (3 studies, 196 participants: RR 9.37, 95% CI 1.83 to 48.4). One study reported a non-significant decrease in fever in the sclerotherapy group (60 participants: RR 0.25, 95% CI 0.06 to 1.08). There was an increased number of infections in the surgery group however this increase was not statistically significant (4 studies, 275 participants): RR 0.31, 95% CI 0.09 to 1.05; I² = 0%). Three studies reported the frequency of pain in the surgery group was higher than aspiration and sclerotherapy group but because of different measurement tools applied in these studies, we could not pool the results. Radiological cure was not reported in any of the included studies. There was no significant difference in haematoma formation between the two groups (3 studies, 189 participants: RR 0.57, 95% CI 0.17 to 1.90; I² = 0%). Only one study reported patient satisfaction at three and six months; there was no significant difference between the two groups. AUTHORS' CONCLUSIONS: Postoperative complications as well as cost and time to work resumption were less in the aspiration and sclerotherapy group; however the recurrence rate was higher. The cure rate in short-term follow-up was similar between the groups, however there is significant uncertainty in this result due to the high heterogeneity. There is a great need for further methodologically rigorous RCTs that assess the effectiveness of different type of sclerosant agents, sclerosing solution concentration and injection volume for the treatment of hydrocoeles. It is important that the RCTs have sufficiently large sample size and long follow-up period. Studies should evaluate clinical outcomes such as pain, recurrence, satisfaction, complications and cure using validated instruments. The protocols for all studies should be registered in clinical trial registries and the reports of these studies should conform with international guidelines of trial reporting such as CONSORT. Cost-effectiveness studies should also be undertaken.

RESUMO

PURPOSE: The pediatric NSQIP program is in the early stages of facilitated surgical quality improvement for children. The objective of this study is to describe the initial experience of the first Canadian Children's Hospital participant in this program. METHOD: Randomly sampled surgical cases from the "included" case list were abstracted into the ACS-NSQIP database. These surgical procedure-specific data incorporate patient risk factors, intraoperative details, and 30 day outcomes to generate annual reports which provide hierarchical ranking of participant hospitals according to their risk-adjusted outcomes. RESULTS: Our first risk-adjusted report identified local improvement opportunities based on our rates of surgical site infection (SSI) and urinary tract infection (UTI). We developed and implemented an engagement strategy for our stakeholders, performed literature reviews to identify practice variation, and conducted case control studies to understand local risk factors for our SSI/UTI occurrences. We have begun quality improvement activities targeting reduction in rates of SSI and UTI with our general surgery division and ward nurses, respectively. CONCLUSIONS: The NSQIP pediatric program provides high quality outcome data that can be used in support of quality improvement. This process requires multidisciplinary teamwork, systematic stakeholder engagement, clinical research methods and process improvement through engagement and culture change.

RESUMO

PURPOSE: VURD (posterior urethral valves, unilateral vesicoureteral reflux and renal dysplasia) syndrome is the combination of persistent unilateral vesicoureteral reflux associated with an ipsilateral dysplastic, poorly functioning kidney in patients with posterior urethral valves. It was postulated that this syndrome may result in preservation of long-term renal function due to a pressure release pop-off mechanism. We determined the effects of VURD long-term renal outcomes. MATERIALS AND METHODS: We retrospectively reviewed the records of boys diagnosed with posterior urethral valves between 1983 and 2009 at a single pediatric tertiary hospital. Patients were divided into those with and those without VURD syndrome. The outcome of interest was renal impairment, defined as stage 3 or greater chronic kidney disease (glomerular filtration rate less than 60 ml/min/1.73 m(2)). RESULTS: We identified 89 patients, of whom 23 (26%) had VURD. Median followup was 77 and 57 months in the VURD and nonVURD groups, respectively. Seven patients (30%) with and 26 (39%) without VURD had significant renal impairment. Survival analysis using a Cox proportional hazard model showed no association between VURD and renal impairment (HR 1.05, 95% CI 0.65-1.70). The main predictors of renal function were the creatinine nadir and patient age at diagnosis. CONCLUSIONS: VURD syndrome does not seem to have a long-term protective effect on renal function.

RESUMO

BACKGROUND: To introduce the role of fibrin sealant and preputial acellular matrix (PAM) as a new source of inert collagen matrix for urethral reconstruction. METHODS: A ventral urethral segmental defect was created in 24 male rabbits divided into four groups. In group 1 (G1), urethrotomy was closed in layers. In group 2 (G2), closure was followed by applying fibrin sealant. In groups 3 (G3) and 4 (G4), urethroplasty was performed with a patch graft of PAM, and in G4, fibrin sealant was also applied. Serial urethrography was performed before and after the operation. Then, the animals were euthanized, and their urethra was excised 1, 3, and 9 months postoperatively for further electron microscopic examination, terminal deoxynucleotidyl transferase dUTP nick-end labeling (TUNEL) technique, and immunohistochemical (IHC) staining with CD34, CD31, desmin, SMA, and α-actin. RESULTS: In G1 and G2, the fistula repair failed in all the time points. In G3 and G4, serial urethrography confirmed the maintenance of a wide urethral caliber without signs of strictures or extravasations. Satisfactory vascularity was observed in G3 and G4 during the whole study, which was more significant in G4 after 9 months of follow-up. The presence of a complete transitional cell layer was confirmed over the graft in G3 and G4 in all time points. IHC staining confirmed the effectiveness of fistula repair in G3 and G4, 3 months postoperatively. CONCLUSION: This rabbit model showed that PAM combined with fibrin sealant may herald a reliable option for repairing segmental urethral defects.

RESUMO

Neuroblastoma (NBL) of the urinary bladder is an extremely rare diagnosis, with only 6 cases reported in the literature to date. We report the case of a 3-year-old boy who presented with gross hematuria, and was diagnosed with bladder NBL after partial cystectomy. Two-year follow-up has been unremarkable. This case highlights a rare neoplasm of the urinary bladder in a pediatric patient.

RESUMO

Keloids are abnormal scar tissue growths that extend beyond the original area of injury, occasionally occurring post-surgery. Risk factors for keloids include skin trauma, infection, prolonged wound healing and individuals of certain ethnicities. Keloid formation on the penis, however, is a rare occurrence even among circumcised males, and can produce both aesthetic and functional complications. We document the tenth patient in the literature, to our knowledge, to present with a keloid of the penis.

RESUMO

BACKGROUND/PURPOSE: Intratesticular cysts are a rare clinical entity in the pediatric population. Recently, testes sparing surgery has been recommended. We share our experience with the management of pediatric testicular cysts. METHODS: A retrospective review of all pediatric patients referred for intratesticular cysts was conducted at a single pediatric institution from 2002 to 2010. Charts were evaluated for patient demographics, diagnosis, and management. RESULTS: Seven patients were identified and included in this series. After partial orchiectomy, the final diagnosis in three patients was epidermoid cyst. Three further patients were diagnosed as mature cystic teratoma, with two of these demonstrating adjacent intra-tubular germ cell neoplasia (ITGCN). One cyst in the series underwent spontaneous resolution after eight months. CONCLUSION: All of the cystic lesions in our case series were benign with one undergoing complete resolution. The remainder became smaller and developed a solid component prompting surgery. The pre-pubertal findings of ITGCN in two patients raise a dilemma regarding the optimal long-term management for these patients. Initial conservative observation is an option for the majority of pre-pubertal cystic testicular lesions until such time that testis sparing surgery is deemed technically feasible. Testes sparing surgery should be advocated in those patients undergoing surgical management.

RESUMO

Large pelvic cysts and moderate to severe hydroureteronephrosis were found after investigating hypertension in a 16-year-old child with Marfan's and known pelvic dural ectasia. Follow-up magnetic resonance imaging demonstrated extensive ectasia of the dural sac at the sacral level with displacement of the bowel, bladder and bilateral ureteric obstruction with accompanying hydroureteronephrosis that was advanced compared to prior imaging. Postural headaches secondary to cerebrospinal fluid leak and progressive hydroureteronephrosis prompted a combined neurosurgical and urologic resection of the pelvic masses. In this report, we discuss the preoperative evaluation and management of this rare form of bilateral ureteric obstruction.

RESUMO

PURPOSE: Transrectal ultrasound guided prostate biopsy can lead to urinary tract infections in 3% to 11% and sepsis in 0.1% to 5% of patients. We investigated the efficacy of rectal cleansing with povidone-iodine before transrectal ultrasound guided prostate biopsy to reduce infectious complications. MATERIALS AND METHODS: Between 2009 and 2011, 865 men were prospectively randomized to rectal cleansing (421) or no cleansing (444) before transrectal ultrasound guided prostate biopsy. Patients received ciprofloxacin prophylaxis and rectal swab cultures were obtained before transrectal ultrasound guided prostate biopsy. Patients completed a telephone interview 7 days after undergoing the biopsy. The primary end point was the rate of infectious complications, a composite end point of 1 or more of 1) fever greater than 38.0C, 2) urinary tract infection or 3) sepsis (standardized definition). Chi-square significance testing was performed for differences between groups and a multivariate analysis was performed to assess risk factors for infectious complications. RESULTS: Infectious complications were observed in 31 (3.5%) patients, including 11 (2.6%) treated and 20 (4.5%) control patients (p = 0.15). Sepsis was observed in 4 (1.0%) treated and 7 (1.6%) control patients (p = 0.55). On multivariate analysis resistance to ciprofloxacin in the rectal swab culture (p = 0.002) and a history of taking ciprofloxacin in the 3 months preceding transrectal ultrasound guided prostate biopsy (p = 0.009) predicted infectious complications. CONCLUSIONS: Rectal cleansing with povidone-iodine before transrectal ultrasound guided prostate biopsy was safe, but the 42% relative risk reduction of infectious complications was not statistically significant. Patients who have received ciprofloxacin within 3 months of transrectal ultrasound guided prostate biopsy should be considered for alternate prophylaxis or possibly a delay of biopsy beyond 3 months.

RESUMO

OBJECTIVE: To interrogate case-log data for American and Canadian urology residents to define trends in minimally invasive surgery (MIS) and open surgery and compare operative experiences between these 2 groups. METHODS: Case-log data from 2004 to 2009 for American urology residents was compared with Canadian residents for 8 index cases, which are routinely performed in both an MIS and open approach. These included nephrectomy (donor, radical, simple, partial), prostatectomy (radical), adrenalectomy, pyeloplasty, and nephroureterectomy. RESULTS: Linear regression analysis demonstrated a significant increase in the percentage of MIS radical prostatectomies performed by American residents (11.2%-52%), compared with Canadian residents (0.74%-11.2%). There was also a significant increase in the percentage of MIS donor nephrectomies by Canadian residents (5.6%-68.7%), compared with American residents (70.1%-89.1%). For Canadian residents, exposure to the following 3 MIS procedures increased significantly over open approaches: adrenalectomy, radical prostatectomy, and donor nephrectomy. For American residents, all index procedures with the exception of adrenalectomy underwent a significant increasing trend (all p < 0.05). CONCLUSIONS: Trends for 8 index procedures confirm a continuing shift towards MIS for the majority of procedures in both countries. Differences may be only temporal and relate to dissimilar health care delivery models with a resultant lag in the adoption of laparoscopy and robotics in Canada. The impact of these trends upon ultimate surgical competence of graduates remains to be seen.
