Preoperative Cardiovascular Risk Assessment Prior Non Cardiac Surgery: A Case Series of Patients Undergoing Urological Surgery in Ngaoundere, Cameroon

Background and objective: Preoperative cardiovascular risk control is critical to reducing the frequency of perioperative cardiovascular events and improving the survival and quality of life of surgical patients. This study aimed at assessing preoperative cardiovascular of patients undergoing urological surgery in Ngaoundere, Cameroon. Methodology: A cross-sectional study was carried at the urological surgery department of the Ngaoundere Islamic Clinic. Participants’ sociodemographic, clinical and biological data were collected and analyzed using Sphinx V5 software. Results: A total of 58 patients were included in the study. Their mean age was 61.33 ± 16.16 years. The most represented age group was the one over 70 years (34.50%). In total, 50 (86.20%) patients had low risk surgical procedures and 20 (34.5%) patients had poor functional capacity. Lee score was calculated for all patients with low functional capacity. Of these patients, 17 (85%) had a low risk of cardiovascular events. Conclusion: The present study reveals a low preoperative cardiovascular risk in urological surgery in Ngaoundere, Cameroon;however, this observation does not exclude the need of systematic evaluation of preoperative cardiovascular risk for better prevention of postoperative complications, in surgical setting in our context.

Tunica albuginea versus buccal mucosa graft urethroplasty for anterior urethral stricture: A prospective randomised pilot study

Objective:The objective of the study was to compare the outcome of tunica albuginea urethroplasty(TAU)and buccal mucosa graft(BMG)urethroplasty for anterior urethral stricture.Methods:Thirty patients who met the inclusion criteria were randomised into two groups:TAU(Group A)and BMG urethroplasty(Group B).Surgical outcome was evaluated with pre-and post-operative work-up involving retrograde urethrogram,voiding cystourethrogram,uroflowmetry,and urethroscopy.Patients were followed up till 1 year.Results:Mean duration of surgery was statistically significant between two groups(p=0.0005).Maximum urine flow rate was comparable when compared between two groups(p=0.22)but statistically significant when compared pre-and post-operatively(p<0.001).At follow-up of 1 year,the successful outcomes were 80% in Group A and 87%in Group B.A total of five patients who had unsuccessful results required redo urethroplasty.Complications were minimal in both the groups.Conclusion:TAU provides outcomes equivalent to those of BMG urethroplasty.TAU has less operative time,easy to perform,and beneficial in patients with poor oral hygiene.

Performance in the Fundamentals of Laparoscopic Surgery: Does it reflect global rating scales in the Objective Structured Assessment of Technical Skills in porcine laparoscopic surgery?

Objective:To correlate the utility of the Fundamentals of Laparoscopic Surgery(FLS)manual skills program with the Objective Structured Assessment of Technical Skills(OSATS)global rating scale in evaluating operative performance.Methods:The Asian Urological Surgery Training and Educational Group(AUSTEG)Laparoscopic Upper Tract Surgery Course implemented and validated the FLS program for its usage in laparoscopic surgical training.Delegates’basic laparoscopic skills were assessed using three different training models(peg transfer,precision cutting,and intra-corporeal suturing).They also performed live porcine laparoscopic surgery at the same workshop.Live surgery skills were assessed by blinded faculty using the OSATS rating scale.Results:From March 2016 to March 2019,a total of 81 certified urologists participated in the course,with a median of 5 years of post-residency experience.Although differences in task time did not reach statistical significance,those with more surgical experience were visibly faster at completing the peg transfer and intra-corporeal suturing FLS tasks.However,they took longer to complete the precision cutting task than participants with less experience.Overall OSATS scores correlated weakly with all three FLS tasks(peg transfer time:r=0.331,r^(2)=0.110;precision cutting time:r=0.240,r^(2)=0.058;suturing with intracorporeal knot time:r=0.451,r^(2)=0.203).Conclusion:FLS task parameters did not correlate strongly with OSATS globing rating scale performance.Although FLS task models demonstrated strong validity,it is important to assimilate the inconsistencies when benchmarking technical proficiency against real-life operative competence,as evaluated by FLS and OSATS,respectively.
