RESUMO
Objective The aim of the study was to assess the safety of preserved renal function after standard percutaneous nephrolithotomy (PCNL) in patients with a single functional kidney. The main parameters to focus on were serum creatinine levels and any associated complications. Materials and methods This retrospective cohort study was conducted in an Eastern population in a single center from 2016 through 2023 at The Kidney Centre Postgraduate Training Institute, Karachi, Pakistan. Results Out of the total 1,550 PCNL procedures performed on adult patients, 47 patients had a solitary functioning kidney with stones, which were evaluated. The stone clearance rate was 95.74% (45 patients), with a mean operative time of 85.96 minutes. Most patients, i.e., 33 (70.21%), had an infracostal approach, and single tract management was sufficient for 45 (95.74%) patients. The most common complication was transfusion, which was required in five (10.64%) patients. Mean preoperative hemoglobin dropped by 1.43mg/dL postoperatively, and mean serum creatinine decreased from 2.45mg/dL to 1.97mg/dL. Among the 24 (51.06%) analyzed stones, all were calcium oxalate. Conclusion In challenging situations such as a solitary kidney with a large stone, PCNL is the procedure of choice. However, the refined technique is of paramount importance. Overall, the use of PCNL in these unique conditions is safe and rewarding.
RESUMO
Introduction Medical students choose to pursue their careers based on multiple internal and external factors. These factors, in turn, not only affect their personal future but the overall status of the health care system of their country. A recent decline in the interest of medical students towards the surgical career is being observed and, therefore, the factors influencing their choice need to be evaluated. We aimed to identify these factors in medical students of a public sector university of Karachi. Methods A cross-sectional study was conducted at Dow Medical College from April 2018 to May 2018. A pre-tested questionnaire was administered to a sample of 250 students. Besides sociodemographic factors, the choice of career was identified and the factors that influenced it were assessed. Students' opinions were collected using a Likert scale. Data were entered and analyzed using the IBM Statistical Package for the Social Sciences 23.0 (IBM, NY, USA). Frequencies were calculated for individual variables. The chi-square test was used to measure statistical differences between categorical variables and a p-value of <0.05 was considered to be significant. Results In this study, 224 out of 250 questionnaires were returned with complete data, yielding a response rate of 89.6%. We found that 48.2% of students reported a desire to pursue a career in surgery. Students whose fathers were more qualified and belonged to the field of health care were more likely to pick a surgical career (p-value of 0.034 and 0.039, respectively). Students who were willing to pursue a path in surgery more often thought that the social standing of surgeons had its importance (p=0.037). These students also agreed that high salary has a role to play in affecting the choice of career (p=0.023). The most common factors that encouraged students for the choice of a surgical career included the practical implication of skills (57.4%) followed by an academic interest in the field (53.7%), and high income (42.6%). The most common discouraging factors included lifestyle and long working hours (56.9%), followed by less academic interest (31%). Conclusion Our study provides a valuable insight into the factors that influence the choice of medical students for pursuing a career in surgery. We also identified the factors that demotivated them from doing so. In our opinion, better incorporation of surgery into the curriculum, proper attention given to students during their surgical rotation and restructuring of the surgical training program are some of the ways that may improve the interest of students in the field of surgery.
