FREQUENCY OF COMPLICATION OF ENDOUROLOGY PROCEDURES AND CLAVIEN GRADING

Objective: Purpose of this study was to establish supplementary criteria for the Clavien-Dindo classification to standardize the evaluation of postoperative complications. Methodology: This was a cross-sectional observational study using non-probability consecutive sampling in which 142 patients undergoing endourology procedures from 29th July 2015 to 28th January 2016 at the Department of Urology, Jinnah Postgraduate Medical Center, Karachi after taking ethical approval. Patients between the ages of 30 to 60 years of either gender undergoing endourology procedures in which duration of procedures was ≥4 weeks were included for this study after taking informed consent. Known diabetics, hypertensive or patients having cardiopulmonary diseases were excluded from the study. Post procedure patients were followed and the final outcome was recorded in terms of complications and grades of complications were reported. Data were analyzed on SPSS version 20. Descriptive statistics was performed. Results: Among the total of 142 patients of either gender with age between 30-60 years having a mean age of 48.72 ± 8.71 years, undergoing endourology procedures of 4 weeks or more were evaluated to determine the frequency of complications and different grades of complications using Clavien grading system. The results showed that there were 92 (64.8%) males and 50 (35.2%) female patients. Majority of the patients, i.e. 113 (79.6%) were found to have no complication after undergoing end urology procedures while 29 (20.4%) of the total patients had developed complications. (Figure 1) As far as complication grades according to clavien grading system are concerned, 05 (7.2%) were grade-1, 14 (48.3%) were grade-2, 04 (13.8%) were grade-3, and 06 (20.7%) were observed with grade-4 complications. Conclusion: The present study concluded that although majority of the patients recorded to have no subjective or objective complications. Those patients who experienced any complication, were classified according to clavien grading system which was beneficial in recognizing and managing the complications with regards to the degree of severity.
