Insights
Endourological surgery has rapidly advanced, becoming the dominant surgical approach over open surgery for urological procedures. This shift reflects significant progress in minimally invasive techniques for prostate, bladder, ureter, and kidney operations.
Area of Science:
- Urology
- Surgical Innovation
- Medical Statistics
Background:
- Analysis of inpatient and operational data from April 1971 to December 1986.
- Total of 4,984 operations were statistically analyzed over a 15-year period.
Purpose of the Study:
- To evaluate trends in urological surgical procedures over a 15-year period.
- To assess the shift in prevalence between endourological and open surgery techniques.
Main Methods:
- Retrospective statistical analysis of surgical case logs.
- Categorization of operations by anatomical site (prostate, bladder, ureter, kidney).
- Comparison of surgical approach percentages (endourological vs. open) across different time intervals.
Main Results:
- Prostate operations were most frequent (1,088 cases), followed by bladder (991), ureter (816), and kidney (719).
- Endourological surgery increased from 20.5% (1975-1977) to 62.6% (1984-1986).
- Open surgery decreased from 79.5% (1975-1977) to 37.4% (1984-1986), indicating a complete inversion of rates.
Conclusions:
- There has been a dramatic and rapid progression in endourological surgical techniques.
- Minimally invasive approaches like percutaneous nephrolithotomy (PNL) and transurethral lithotripsy (TUL) are increasingly favored.
- The data highlights a significant paradigm shift towards endourology in contemporary urological practice.
Abstract:
Statistical analysis of the inpatients and operations in our department from April, 1971 to December, 1986 revealed a total of 4,984 operations. Operations on the prostate were the most frequent (1,088 cases), followed by operations on the bladder (991 cases), on the ureter (816 cases), and kidney (719 cases). Among the operations, the percentage of endourological surgery and that of open surgery was 20.5% and 79.5% during the three years from 1975 to 1977, but in the recent three years from 1984 to 1986, these percentages were 62.6% and 37.4%, respectively, the rates being completely inverted. This shows that new endourological surgery, such as PNL, TUL, is progressing rapidly these years.
